My portable grandfather refreshes every week

"Gather, gather! The undead are coming! The undead are coming!" The old man's voice rang out instantly.

Dozens of people took up weapons. Some of them were emaciated and looked like bamboo poles, as if they could die at any moment. Others were extremely old, with wrinkled and withered faces like those of an old man. This was the backlash after their life force had been squeezed too hard.

But nobody cares here, because when survival is already a luxury, squeezing out one's life force to gain temporary strength is the ultimate training method.

However, the bone dragons did not stop advancing because of their reaction, and they didn't even care about the speed bump blocking their way.

There used to be many small settlements like this, but they were all occupied and controlled by warlords and became gathering places for farmers to produce goods. The fortifications built were not intended to defend against such a behemoth as the Bone Dragon.

However, at this moment, such a behemoth did not care about these small fry at all, but the skeletons following the bone dragon were like madmen chasing after the scent of the living.

"Get underground! Get down there and use shields and spears to hold off the skeletons and ghouls. That's our only way out!" he roared immediately.

The bone dragons were monsters they could not stop, but the bone dragons were not interested in them. Their only way to survive was to hide underground and block those low-level undead.

Only after the bone dragon has completely departed, and the vast majority of the undead have followed it away, leaving only a small number of undead, will they have their only chance to eliminate these undead and reclaim their settlement.

It was also the only chance to survive!
He gritted his teeth, sweat pouring down his body, once again squeezing out his life force.

I am grateful to the Empire for teaching me the basic magic refining methods in the academy, and I am grateful that I did not sleep in class but chose to study hard.

But if I could return to the era of the former empire, I would fight tooth and nail to learn as much as possible in the school! Even if I were to die, I would die in the school, dying amidst that knowledge!

Whether it's refining knowledge with magic or military formations.

I swear to offer my heart to the old demon king! I will defend the empire to the death, and I will never allow it to be destroyed by those pathetic insects in just 14 years!

"Roar!"

The ghouls and skeletons, these low-level undead, crashed into the ironwood fortifications. The young men in the front row desperately held their shields, not knowing how long they could hold out. Meanwhile, those behind them fought desperately, thrusting their weapons through the gaps in the shields again and again, piercing through the ghouls and crushing the spines of the skeletons.

The best solution is to build an extremely deep bunker, so deep that even the dead cannot sense the presence of the living below.

But that was too far-fetched for them.

They could only dig a small tunnel, and they had to leave a gap for the undead to attack, because only in this way would the undead gather in this gap instead of going crazy and digging three feet into the ground.

Otherwise, the few meters of soil above their heads would soon be dug through by the undead, and they would be trapped like turtles in a jar.

Those at the rear of the army desperately squeezed out their life force to generate a surge of adrenaline and temporary strength, pulling back their spears and piercing through once more.

It's incredible that such a disciplined military formation could emerge from such a small settlement, but this is what he learned in school. All the knowledge he once thought was insignificant has now become his trump card for survival.

"Crack!" The shield shattered.

"Hold on! Hold on! Don't let the ghouls catch you!" he commanded, thrusting his spear forward.

However, a scream rang out, the scream of a young man caught by a ghoul. In an instant, the army formation collapsed, and everyone around him abandoned him and prepared to flee.

Fear spread again in an instant. It wasn't because they were cowardly, but because anyone injured by the undead would develop a high fever after 10 minutes and die completely in about 20 minutes, turning into a monster no different from the zombies in the horde of undead!

Therefore, once scratched, there was no hope of recovery; this person could be considered another ghost!

Therefore, the already crumbling army formation collapsed in an instant, and the undead began to tear open from this opening, ignoring the infected person and rushing towards the others.

"Is it over?" These were the old man's last thoughts.

They're finished. They've been clinging to life until now. They should have died long ago, but they've been desperately trying to stay alive.

Just as the slaughter of the undead was about to begin, and he had completely given up resistance, preparing to pull out a dagger to commit suicide, the light shone brightly in front of everyone.

The next moment, in the light, the bone dragon's head was severed in an instant, and its massive body was also cut in half vertically in perfect symmetry. As if there were no obstacles, it was as if a hot knife was cutting into butter. The bones, which were far stronger than alloys, did not break at all, but were easily cut open.

After slicing through the bone dragon, the light wheel instantly shattered into billions of smaller light wheels, which, as if possessing a tracking function, sliced ​​through all the surrounding undead.

The low-level undead, enveloped by the bone dragon, didn't even have time to be cut by the light wheel; they spontaneously combusted and turned to ashes simply from the light's illumination.

As if they had met their nemesis, the next moment, the large horde of undead swept up by the bone dragon turned into burning ghost fire. They were unable to launch any counterattacks and were reduced to ashes.

Everyone stared blankly at the sky, but the light was so bright that they couldn't even see the figures within it. They could only see a demi-human that resembled a combination of a centipede and a lizard, a characteristic once unique to the demon race.

When there were hundreds of races, the demon race was just like that. Ugly yet powerful, it looked like a demon from hell, hence the name demon race.

But now, there are hardly any demons left in the entire world, perhaps only a handful.

Among the crowd, only the oldest man saw the old demon emperor in the light. He recognized the figure; it was the image that had appeared countless times in his dreams, the image that had been imprinted in various books when he was in school.

The first demon king to unify the entire world!

He would almost always return to the classroom in his dreams and see the emperor's portrait. And now, the emperor was actually standing in front of him, as if in a dream, as if in a fantasy...

The old man knelt on the ground, tears streaming down his face, burying his aged head deep in the earth. Tears and snot mingled together as he cried out, "Demon King, Vani, the first graduate of Imperial Capital Academy No. 4, respectfully welcomes the Demon King's arrival!"

At this moment, a towering defensive tower, formed from condensed light and resembling the sun, rose in the very center of the settlement. After witnessing this miracle, everyone burst into tears, and many even thought they were dead and that they were just dreaming.

And from the Demon King's mouth, they heard a sentence that would excite anyone.

"Empire, your emperor has returned!" the old demon emperor said, looking at the old man.

……

This was all just Xue's deliberate mystification. Whether it was the timed rescue or the old demon emperor's appearance to win people's hearts, it was all a plan discussed by the two of them.

The two of them had come here after seeing the bone dragon. They landed directly in the forest occupied by the undead. They didn't see any landmarks along the way, so Xue Lude also put his serious spirit into practice.

I don't know who I am or where I am, but I'm going to go on a killing spree!

So he went on a killing spree, and the undead were easily sliced ​​apart in his hands like tofu.

Strangely enough, even the undead of this world are completely suppressed by the Holy Light. In addition, Xue Law directly purchased a large amount of magma from the Holy Mountain at a high price. Therefore, the quality of Xue Law's Holy Light is now even better than that of Pope Alora.

Therefore, Xue's Law can now be described as a walking embodiment of divine light.

It is quite possible that these bone dragons did not migrate on their own, but were accidentally driven here by him and the old demon emperor, which is why the settlement here suffered this undeserved disaster.

The bone dragon showed no regard for the survivors in the settlement, perhaps because it had developed intelligence and understood that avoiding the glowing treasure behind it was infinitely more important than killing the survivors; if it was too slow, it would be waiting to die!
So it fled at top speed, but was still caught up by Xue Dinglu and the Old Demon Emperor.

However, after seeing how familiar the military formation of this settlement was, the old Demon Emperor stopped Xue Luding, wanting to observe what was going on.

Then, when he realized that this group of people were still using the military formations and magic refining techniques from the Imperial era, the old Demon Emperor's face showed three parts nostalgia, three parts dissatisfaction, and three parts emotion. At the last moment, he and Xue Luding worked together to save people at the last minute.

Perhaps, seeing that even under such circumstances, the academy he had built by sucking the blood of the empire could still be of use, the old Demon Emperor was perhaps feeling sentimental, reflecting that his former empire had not been completely destroyed, but had still left traces of it in this world.

The two had discussed it beforehand.

This time, the old Demon Emperor was in charge. After all, this was his own world, his home. Xue Luding was just a henchman, so he didn't stop the old guy from winning people's hearts in this way.

The old man only needs to put on a show and say, "Your emperor has returned." But Xue, behind the scenes, has to consider many more things: he needs to make it glow, instantly kill the undead, and quickly build this Tower of Light.

The old Demon Emperor looked as if he had come from Dandong and changed into a snow-white outfit.

The old Demon Emperor began questioning these people.

How long has it been since the empire fell? What happened afterward? And what is the current situation? Xue Daolu is seriously starting to build the Holy Light Defense Tower here.

The technology originated from interstellar corps, enabling the rapid deployment of automated sentry towers. It cost Xue's Law 998 credits, but for Xue's Law now, that's a drop in the ocean! Buy it!

Meanwhile, Xue's Law added a bit of holy mountain magma to the power supply system, giving the watchtowers' attacks a built-in holy light enchantment.

Thus, this magnificent Holy Light Watchtower, over thirty meters high, was completed.

Putting aside everything else, this thing was able to destroy the mythical bone dragon after recognizing its automatic attack.

Even faster, just after Xue Luding had set up the automatic attack mode of the watchtower, the old demon emperor returned to Xue Luding's side. His emotions seemed extremely complex, with both anger and a kind of indescribable sense of relief.

"What's wrong? Why do you look so complicated?" Xue Dinglu asked when he saw the old Demon Emperor.

The old demon king didn't answer directly, but instead asked, "Do you have a cigarette?"

"You've only been on Earth a few days and you've already picked up this bad habit?" Xue Dinglu rummaged through his consciousness space and indeed found a pack of Huangshan cigarettes. He handed the cigarettes to the old Demon Emperor.
He lit a cigarette, took a deep drag, and then cursed, "You damned bastards! You're dead!"

When the pure essence of Chinese culture was uttered by the people of this other world, Xue Dinglu had to exert all his strength to keep himself in check.

"What's wrong?" he asked in return.

The old Demon Emperor took another deep drag on his cigarette and said, "I originally thought that even if the empire fell, the concept of unification would still be deeply rooted in people's hearts, and there would definitely be successors to inherit my ideals and continue to achieve unification..."

"But now I realize that after unification, what awaits us may not be another unification, but rather the Five Dynasties and Ten Kingdoms period..." The old Demon Emperor silently told Xue Dinglu what he knew.

Xue Lude was stunned for a moment. This old man had attained enlightenment in Longchang on Earth, and his knowledge of Earth's history might even be stronger than that of Xue Lude, an Earthling who only knew history from literature and videos after middle school.

However, when he mentioned the "Five Dynasties and Ten Kingdoms", Xue Dinglu was able to roughly understand what kind of situation this world was in.

This is a unique language encryption system of Dongda University. A single idiom acts like a hyperlink, unfolding almost all the information in Xue's mind.

"How much stronger is it compared to the Five Dynasties and Ten Kingdoms period?" Xue Dinglu asked tentatively.

Although he didn't have a systematic understanding of this era, he knew that it was an era where humans were treated worse than pigs and dogs, and human flesh was the most popular food of the time. There really was a baby in the claypot rice.

In this day and age, exchanging children to eat is considered elegant; it's practically a group of cannibals among cannibals competing to see who is the worst, a truly glorious moment for humanoid apes.

Xue's Law thought, surely it couldn't be worse than the Five Dynasties and Ten Kingdoms period, right?
The old demon emperor stared at Xue Lude with a death stare, making Xue Lude feel embarrassed and offer him another cigarette.

"Even worse!"

Xue Law: "..."

How could they be worse than those ape-like creatures from the Five Dynasties and Ten Kingdoms period? Don't lie to me!

Unexpectedly, the old Demon King said, "Do you know how people in this world avoid becoming undead after death?"

"After death, everyone's corpse will be eaten, and everyone will share it..."

Xue Law: "..."

"Why not burn it?" Xue Luding's face began to contort as he voiced his question, because burning it would also prevent the birth of the undead.

"Your words are like those of that emperor who asked why he wouldn't eat minced meat." (End of Chapter)
