Dong Qi was unaware that Liu Yi had deliberately concealed the combat power of his companion vines. He only thought that the growth Liu Yi mentioned was simply that the companion vines would grow more branch vines, allowing them to attack different targets each time.

Therefore, Dong Qi did not pay attention to Liu Yi's companion vines, which would occasionally attack those White Walkers who were crippled by laser cannons.

However, what Dong Qi didn't notice was that a touch of green had appeared on the ground within the laser cannon's attack range at some point.

Meanwhile, the weeds that had sprouted on the ground at some unknown time were gradually expanding their coverage, spreading across the entire battlefield.

The White Walker corpses that were killed or torn apart were pierced by weeds on the ground when no one noticed, and then the White Walker corpses, like deflated balloons, gradually began to dry out.

Fortunately, the battlefield was in the midst of its most intense melee, so few people noticed the changes in the White Walker corpses on the ground.

Even if someone happened to notice this anomaly, they would only think it was the work of someone on the battlefield.

After all, the combat methods used by the participants in this chaotic battle were varied and numerous, and no one knew exactly how many types there were.

At this moment, the attack of the White Walker army was just like a monster siege in a game, and Dong Qi and the other participants were like the players in the game.

Although they could kill a large number of White Walkers with each attack, the vacuum created by the death of those White Walkers was immediately filled by a continuous stream of new White Walkers.

As the cannon fire on the fortress walls had just ceased, all the combat personnel outside the city were in high spirits. Fueled by the high morale of the cannons, they were filled with fierce fighting spirit as they faced the White Walkers charging toward the fortress.

However, after this intense battle had lasted for more than an hour, most of the people outside the city were already exhausted.

After all, this is reality, not a game where you can control a little character on the screen to fight by clicking the mouse.

Each attack requires expending physical strength.

They also need to be careful and cautious when facing the attacks of the White Walkers.

After all, although the White Walkers' own combat strength was far lower than theirs, their sharp claws and fangs could still tear their clothes apart.

Therefore, even when they charge into the army of White Walkers and wreak havoc, they will still be careful to prevent the White Walkers around them from getting close and attacking them.

However, such behavior requires them to maintain a high level of concentration for a long time, so most people cannot sustain such a battle for long.

Even the more famous battles of World War I and World War II in modern times on Earth, although the records show how long the protracted battles lasted, actually did not take much time to escalate during the actual engagements.

The most time-consuming part of the battle was not the fighting between the two sides, but the transfer of positions, the setting up of trenches and a series of logistical tasks. The actual fighting usually ended in one or two hours.

This only involves using firearms for long-range combat, and does not require constant mental focus to defend against attacks from nearby enemies.

Meanwhile, the combatants on the battlefield had gradually shifted from charging directly into the White Walker army and slaughtering indiscriminately to retreating to the vicinity of the city walls and focusing on defense.

Perhaps the commander standing on the city wall noticed that the combat personnel below needed to rest, or perhaps the heavy firepower on the city wall, which had been overheated, had cooled down.

As a result, the heavy firepower that had stopped on the city walls resumed, creating a large vacuum area in the White Walker army once again.

While the long-range firepower on the city walls eliminated the White Walkers at medium and long range, the combat personnel near the city gates also suddenly began to exert their strength, and in just a few minutes, they wiped out all the White Walkers near the city gates.

After all the White Walkers near the city gates died, the previously tightly closed gates reopened, and then wave after wave of scythe-wielding mechanical wolves rushed out of the gates.

Instead of charging directly into the White Walker army to fight as before, the scythe-wielding mechanical wolves remained not far from the city gate, guarding it in a battle formation.

Once the scythe-wielding mechanical wolves ceased to appear at the city gate, the battle groups near the gate entered in an orderly but rapid manner and returned to the fortress.

Seeing this, Dong Qi patted Liu Yi, who was inexplicably excited, and casually asked, "What's wrong with you? Why are you so excited?"

Although Liu Yi was extremely excited at this moment, he did not directly confess when Dong Qi asked him, but he did reveal some of the truth:

"You should know that my companion vine needs to absorb the flesh and blood of monsters to become stronger. Although there were quite a few monsters in the secret realm of Blue Star, the battles ended quickly, leaving little time for the companion vine to absorb the flesh and blood of the monsters."

According to what I've heard, this war will last at least half a month and could last for more than three months.

Given the long duration and the fact that the ground is now littered with the corpses of those White Walkers, even absorbing a single White Walker wouldn't provide much strength for the companion vines.

But nothing can withstand such a large quantity. I reckon that once this war ends, my symbiotic vines will experience an unexpected boost.

Although Dong Qi sensed that Liu Yi wasn't telling him the truth, he wasn't curious about Liu Yi's hidden secrets and therefore wouldn't delve into it.

So he asked directly, "Now that the city gates are open, it seems that people are being allowed to go back to rest and for the rotation of combat personnel."

I'm planning to head back to the city first. Are you coming back with me, or will you stay here and continue fighting?

Hearing Dong Qi's question, Liu Yi looked at Dong Qi with some surprise, and then subconsciously blurted out, "You've been standing here the whole time, why aren't you taking advantage of this time to earn more contribution points? Why are you going back to the fortress so early?"

"You know perfectly well that after the city gates close this time, they won't reopen for at least two hours. Isn't it a bit too early to go back now?"

Dong Qi ignored Liu Yi's advice. This time, Dong Qi's return was not based on Li Peng's previous advice.

After all, Dong Qi initially thought Li Peng's advice was quite correct, but after seeing Li Peng off, he carefully considered it and found some problems.

For example, the city gates would return to the city for repairs every time they were opened. Simply put, the number of times the city gates were opened could be divided into odd and even numbers.

Dong Qi fights outside on odd-numbered days and rests in the city on even-numbered days.

If the city gates open on odd-numbered days and Dong Qi goes out to fight, but then close on even-numbered days, wouldn't Dong Qi still be left outside the city?

Once he understood this, Dong Qi immediately forgot about Li Peng's suggestion.

Dong Qi's return to the city this time was not out of boredom, but rather because he was preparing to use some contribution points to exchange for the remaining manufacturing data of the mechanical creations he had his eye on.

That's why it's easier to earn contribution points during wartime.

Dong Qi, who was originally just a private first class, has now unknowingly risen to the rank of sergeant first class.

To be promoted to a first-class sergeant, one needs to spend over 100,000 to nearly 200,000 contribution points.

This means that Dong Qi has killed at least a million Otherworlders during this period.

Dong Qi hadn't expected that in such a short time, the Starfire Flying Boat would be able to kill so many alien demons.

Although Dong Qi felt that such a high kill efficiency was somewhat abnormal, the actual situation was that the laser cannon could inflict fatal damage on a large area of ​​White Walkers every five seconds.

The mechanical wolves that were subsequently sent out could kill two to three White Walkers per second, on average, that were severely injured by the laser cannons.

Not to mention that each attack from the electromagnetic cannon can pierce through an entire straight line, blasting through countless White Walkers.

Therefore, only after all these factors combined could Dong Qi achieve such terrifying killing efficiency against the Otherworldly beings.

Logically speaking, knowing that the Starfire Flying Boat could harvest contribution points so quickly, Dong Qi should have continued to stay here to harvest contribution points and would not have needed to return to the city for rest.

But it was precisely for this reason that Dong Qi chose to return to the city at this time.

Don't forget that before the war started, Li Peng had already helped Dong Qi complete the procedures for automatic promotion of his military rank.

Therefore, if you don't spend all the contribution points you've accumulated right now after the upgrade, they will disappear instantly once you have enough to upgrade to the next rank.

Don't be fooled by the fact that the second batch of personnel who went out to fight were full of energy and high spirits. Don't forget the duration of this war, and that the White Walker army not only maintained this extremely high rate of troop production, but would even send even stronger giant White Walkers to join the war later.

Therefore, although the war seems easy now, it will become increasingly difficult as time goes on.

Therefore, Dong Qi needed to exchange the items he wanted in advance while the military supplies exchange office was still operating normally.

Otherwise, once the outer city falls and street fighting begins, even if you have a lot of contribution points, you won't be able to exchange them for any items.

Seeing that Dong Qi was ignoring his good advice and insisted on returning to the fortress at this time, Liu Yi didn't say anything more. However, after thinking for a moment, he still spoke up and made his request:

"Brother Dong, aren't you preparing to return to the city? Anyway, the city is very safe right now. Why don't you leave your car outside the city for the time being?"

"Just do me a favor. After all, even if you return to the city, this big guy can't drive into the city with you."

Upon hearing Liu Yi's request, Dong Qi did not refuse outright, but instead asked in return, "What is the maximum range of your companion vines?"

Upon hearing Dong Qi's question, Liu Yi instantly realized that he would no longer be able to comfortably stay in the Starfire Flying Boat.

However, Liu Yi understood the situation very well, and even if he had to leave the safe Starfire Flying Boat for a period of time, he did not complain about Dong Qi.

After all, Dong Qi's help was a favor, and not helping was his right.

After the two left the Starfire Flying Boat, they discovered that most of the lone wolves around them had already left the area.

Even those lone wolves who didn't plan to return to the city immediately didn't stay in this area any longer, but gradually shifted the battle zone towards the vicinity of the city gate.

After Dong Qi retrieved the Starfire Flying Boat into his sea of ​​consciousness, he assumed that Liu Yi would accompany him to the vicinity of the city gate.

Even though he wasn't planning to return to the fortress to rest, there were already quite a few White Walkers approaching because of the small number of people fighting there.

For safety, you can temporarily hide in a more crowded area and return here after the second batch of combat personnel arrives.

However, Liu Yi directly rejected Dong Qi's well-intentioned suggestion.

After learning of Liu Yi's choice, Dong Qi did not continue to try to dissuade him.

First, the city gates were only open for a short time, and so many combat personnel needed to enter and exit within that short period. Therefore, if Dong Qi returned a little later, the city gates might close directly, causing Dong Qi to miss this opportunity to return to the city.

The second point is also important: Dong Qi has always respected other people's choices. After all, interfering with other people's choices requires bearing the consequences for them.

Therefore, regardless of Liu Yi's thoughts, Dong Qi will firmly choose to provide support.

After a brief farewell to Liu Yi, Dong Qi rushed towards the city gate and then returned to the city with the others.

Upon entering the city gate, everyone, without exception, had to go through a scanner for inspection.

Seeing this action in the city, Dong Qi suddenly felt that perhaps this war was not as simple as others had described, and that the enemy participants were not just the ordinary White Walkers and giant White Walkers he had heard about before.

After all, every action or measure taken during wartime is never without purpose; they are all countermeasures devised after suffering losses.

Fortunately, it was early in the war, so all the returning combat personnel passed the instrument's detection smoothly.

Without much hesitation, Dong Qi went straight to the supply exchange office and spent the contribution points he had just earned to exchange for the blueprints for the Sniper Mechanical Wolf, the Self-Destructing Mechanical Wolf, and the Mechanical Flying Ant.

To reiterate, the cost of exchanging manufacturing materials for most standard products here is not very high.

Just like the carbonated drinks that used to be produced on Earth, both the formula and the process were essentially semi-public.

But why did counterfeit and substandard products appear in the early days, while with the improvement of technology, those counterfeit products have become less and less common?

It's not that the crackdown has become stronger, but rather that the price gap between genuine and pirated products is gradually narrowing, with genuine products even selling for less than pirated ones in some places.

When there's no profit to be made, all those pirated copies naturally disappear.

The same applies to these standardized mechanical creations in the fortress. In the city-states far behind the human borders, there are very complete manufacturing lines, and the purchase price of raw materials is much lower than that of the front-line fortresses.

Therefore, even with shipping costs and various miscellaneous additional fees, the official selling price is not much more expensive than buying materials and making it by hand.

Therefore, apart from a small group of people who want to assemble and practice on their own and want to learn more about modification, not many people will choose to buy the materials.
