Infinite Sun in the East China Sea

Chapter 38 Breach of Contract
Covered in heavy snow, the New York City Public Library now has only a roof left.

However, guided by the taller buildings around them, the few of them still found their mission target.

Just as they were about to enter the library, Hanasaka Shoko, who had been wearing radio headphones to listen to various information about the disaster, suddenly told them a message.

After three major cyclones originating from the Arctic ended, three unprecedented tropical storms began to form in the tropical regions of the Pacific, Indian and Atlantic Oceans.

This climate change, triggered by the melting of polar glaciers, does not end with the freezing of the Northern Hemisphere.

Of course, this news has nothing to do with the three reincarnations who are about to complete their mission.

The tropical storm wouldn't affect New York for at least a week, and they had arrived here long enough in advance.

Without thinking any more, Xu Feng walked into the library.

After he slid down from the snowdrift, what he saw was Tifa with a worried look on her face.

He took Tifa's hand and turned to look at the others. "Are we the only three Samsaras left alive? It seems that the expert isn't as 'expert' as he said!"

According to the rules of the Lord God, even if the atmospheric science expert Fukuda Qingtai completed the task a few years after they left, he would still come to the Lord God space with several people, without a second's difference.

Now that he is not seen in the main god space, it can only mean that he is dead.

Xu Feng contacted the Lord God and learned that he had earned 1600 reward points in the last game.

A 1000-point reward for passing the level, a 100-point reward for explaining the game, and a 500-point reward for blowing up the toilet.

"It's really... pitifully little!"

Xu Feng couldn't help but shook his head. He took a look at the two worlds he could return to. Now, if he wanted to enter "Stranger" again, he would need a D-level side story to open the world, and 50 reward points were needed to redeem one day of survival time.

There will be no chance to enter again in the short term.

And the world of The Day After Tomorrow...

He could only say that there was almost no chance of scoring high points!

"Is there anything you want to exchange? I want to return the 500 reward points I owe you first." After returning to the main god space, Hanasaka Shoko took the initiative to mention the agreement in "The Day After Tomorrow".

"Are you in such a hurry?" Xu Feng was stunned.

He handed over the reward points without being asked. This teammate is so considerate!
When he was about to arrive in New York, he actually thought about what to exchange after returning to the main god space, and he also thought about what he wanted to buy during that time.

"I'm planning to upgrade the drone and jet wings. However, it's just an idea right now, and I'm not sure if it can be realized. After all, any kind of upgrade requires certain technical support." Xu Feng chuckled. "You've been tired for so long, don't you want to take a good rest?"

"You'd better tell me what you want to use, otherwise I'm afraid I can't help myself!"

Hanasaka Shoko looked distressed.

She said with great grievance, "I worked so hard to get 1000 points, and now I have to give up half of it. I really feel bad! But since we already have an agreement, and you saved my life, I naturally cannot break it."

Xu Feng smiled and shook his head. "My current plan is to weaponize the medium-sized drones and replace the jet wings with Hall thrusters with longer-range thrusters. The former is relatively simple and should take a few days to complete. In my plan, we need two six-rotor medium-sized transport drones and 24 arrows with +3 enchantment."

After hearing what Xu Feng needed, Hanasaka Shoko contacted the Lord God for a moment, and soon, a pile of items appeared in front of her.

She saw what Xu Feng was thinking: "Are you planning to install enchanted arrows on the wings of the drone?"

"Indeed, the wings of this medium-sized drone are already extremely lethal. When spinning at high speed, a person struck by the wings will either die or be crippled. But what if the wings were replaced with arrows imbued with magic such as sharpening?"

In the world of "The Day After Tomorrow", after flying with drones for several consecutive days, Xu Feng has a clearer understanding of rotorcraft drones.

As a means of transportation, it's barely adequate; but this inexpensive prop can be developed into a wide variety of uses.

Not to mention its main jobs like reconnaissance and long-range firepower, this thing can also exert considerable combat power in close combat!
The idea of enchanting the drone with arrows was to make it a melee weapon.

Enchanted arrows are very powerful!

The arrow with enchantment +3 can easily penetrate steel under the acceleration of gravity, and can annihilate the matter in the area of ​​passage into powder. The high-speed spinning enchanted arrow is an unstoppable super chainsaw!

Any matter that gets in its way is cut in two.

The drone is not very large. This drone, which can carry an adult male, is only the size of a suitcase after its wings are folded. To be specific, it is only 0.1 cubic meters.

His space bag is large enough to carry several drones.

Imagine that during a battle, there are drones everywhere in the space ahead, behind, left and right that can easily cut through steel. How can ordinary monsters sneak attack them?
After putting these materials into the space bag, Xu Feng picked up Tifa and walked towards his room while saying, "Shoko, you should first explain some of the rules here to Miss Yamaguchi. As for the more advanced Hall thrusters, let's talk about it after I finish modifying the drone..."

Hall thrusters are also known as current thrusters. Most science fiction aircraft engines are of this type. With the same amount of fuel, their endurance far exceeds that of jet engines.

In the real world, the principle of Hall thrusters has already appeared, but the thrust of the finished products is very small, which makes it impossible for people to fly in the atmosphere. Their significance only exists in space without resistance.

The main god space has a finished product of Hall current thruster with very strong thrust, but the price is a bit expensive.

In addition, assembling and utilizing this electric current thruster also requires relatively advanced knowledge, and Xu Feng cannot guarantee that he can complete the manufacture of this thing during this rest period.

In fact, he didn't put any trust in himself in the success rate of assembling this new flying wing.

——Although the world after tomorrow has suffered a great disaster, it is a modern world after all. Unlike the ancient world of foreigners, there are a large number of scientists and engineers in the world after tomorrow.

The high-tech materials here are very cheap. The manufacturing technology of efficient cold-resistant materials, nuclear fusion technology, artificial starch technology... these technologies that can play a huge role in natural disasters only have a dozen reward points in total.

With this information, he can definitely stir up enough storms in the future world to realize many of his ideas.

A hard night.

While Xu Feng was still in bed, Hanasaka Shoko knocked on the door of his room.

"Here's a drawing I made based on your first idea."

The girl walked into Xu Feng's room, carrying a laptop. "Simply fixing the arrows to the drone's wings isn't feasible. It won't unleash their maximum power, and it will also affect the drone's flight. The best way is to use the arrows as a skeleton to cast the blades. I think this is why you requested a larger medium-sized drone."

"But this requires us to redesign the blades. To be honest, we don't have this level of knowledge. This seemingly simple thing requires extremely advanced knowledge of physics." Xu Feng said, touching his chin.

He is well aware of his level of knowledge and practical ability.

"So I simply copied the various high-efficiency propeller wing designs from the Lord God, looking for the best design to incorporate the arrow into it."

Hanasaka Shoko opened a file containing the design drawings of some drones from the Lord God. The screen finally stopped at a somewhat odd-looking model: "This is the final product."

Xu Feng blinked as he looked at the model on the computer. "I've had this idea before, but isn't this kind of design a bit difficult to manufacture? If you're not careful, the arrow will be destroyed. Enchanted arrows are consumables after all."

"Using a 3D printer, it's not too difficult. In fact, I've already made a propeller blade."

Hanasaka Shoko took out a paddle with a slightly unusual shape.

The tips of the blades are very sharp and glow slightly.

Xu Feng stroked the half-meter-long blade. The ordinary material and the special arrow seemed to be one and the same. He couldn't help but sigh:
"You're so serious, it makes me look like a loser!"

He admired the girl in front of him more and more.

Hanasaka Shoko lowered her head and smiled: "Sometimes, the initial inspiration is the most important. You can also create this kind of thing without me."

Xu Feng also smiled: "Haha, no matter what, let's make this close combat drone first! It's a good opportunity to test the power of this thing."

Hanasaka Shoko nodded. "Well, this level of processing and modification won't take too long. We'll probably be able to see it in an hour or two."

She paused at this point and said casually, "By the way, Miss Yamaguchi has been strengthened."
