Regardless of who it is, Lu Ban must be prepared.

The demonic tide of the Kingdom of Darkness was already turbulent and dangerous, and could only be barely resisted by the burning wizard's torch, let alone completely eradicated.

Without the Grey Tower, the demon tide is like a devastating natural disaster, and humans have almost no way to fight against them.

But Lu Ban is the chosen one of the Land of Silence after all, and he can master some powerful weapons.

Based on the situation of the magic tide, Lu Ban summarized several possible effective methods to fight against the magic tide.

The first is to utilize the characteristics of the magic tide.

Last time, Lu Ban had a [Small-Scale Natural Disaster Generator] that could create a blazing sun for a period of time, but the Demonic Tide needs the light of the blood moon to exert its full power. If Lu Ban could get that radio again, or make something like an artificial sun, he would probably be able to restrain the monsters from a metaphysical perspective.

Lu Ban searched on Baidu for controlled nuclear fusion.

Unfortunately, there are not many countries that are currently working hard to develop this, and the fastest ones can only last for one thousand seconds.

Nuclear fusion itself can be accomplished using a tokamak device, but the high-energy neutron flow released during the process requires a shell made of special materials to block it, otherwise nuclear fusion will become a powerful weapon.

Today's technology is developing at a rapid pace. Even the reverse synthesis of starch from carbon dioxide can be achieved. What all kinds of black technologies lack most is energy. Everyone is eagerly looking at controlled nuclear fusion, and then the experts in the controlled nuclear fusion group can only talk about other things and ask those who are working on materials to speed up the progress, while those who are working on materials are looking at the sinkhole of biochemical and environmental materials and are in tears.

Lu Ban decided to help them.

He thought about it and took out a wrench from the toolbox at home.

[It is a wrench that plumbers carry with them, which makes sense]

[The quality is pretty good, three hits can make your head explode]

Words like these emerged, and Lu Ban believed that this was a very useful wrench.

His right hand manifested [Last Words] and wrote the words on the wrench.

[Made of materials that can withstand nuclear fusion, strong and durable]

As soon as he picked up the pen, the wrench looked brand new. Lu Ban touched the surface, but couldn't tell what material it was made of. It seemed to be somewhat different from metal, but also seemed to be non-metal.

It shouldn't be a big problem anyway.

Lu Ban made an appointment for a courier, and soon the guy came to pick up the package.

"Hello, I'm from Arkham Express. You have a package to send, right?"

The young man was wearing a red and black courier uniform and holding a cardboard box and bubble wrap in his hands.

"Yes, this one."

Lu Ban handed the wrench and a note to the young man.

When the young man saw the wrench, he was stunned for a moment, but out of professional duty, he carefully wrapped the wrench in bubble wrap, put it in the box, sealed it, and looked at the shipping address.

"Uh, Institute of High Energy Physics of the Chinese Academy of Sciences?"

Although he was not well educated, he knew very well that the wrench would be of no use to the Chinese Academy of Sciences.

But based on his professional qualities, the guy still placed the order.

Since it was an express delivery, the package was delivered to the Institute of High Energy Physics in Sichuan the next afternoon. It houses the No. 2 nuclear fusion device, which was also the one that recently broke through one thousand seconds.

However, the express package was not opened immediately because there were too many items delivered.

As we all know, there are many amateur scientists all over the world.

From the perpetual motion machines of the past to the controlled nuclear fusion of today, amateur scientists all want to make a difference in these groundbreaking fields and realize their ambitions. In addition to writing letters to express their opinions, they often mail some random things.

Some people printed out their monographs and sent them over, others sent their notes directly, and after learning about the material problems, some amateur scientists would even mail some miscellaneous materials.

Lu Ban’s package was also placed here, guarded by security guards and sorted by interns.

Intern Xiao Wang is one of them.

He opened a package addressed to the professor, which contained a metal plate and a bunch of printed materials.

After looking at the information and weighing it, Xiao Wang felt that it was just an ordinary stainless steel plate.

He turned it over and saw that there was still some paint on the board, which looked like a license plate number.

Xiao Wang put the "important material" back into the package and prepared to give it to the waste collector later.

He opened another package.

Inside was a thick document, which talked about everyone from Yuanshi Tianzun to Sakyamuni, from the universe to individuals. It was rich in philosophical thoughts and mixed with a little discussion on the current social situation, but I didn't find any connection with their scientific research.

Xiao Wang put the thing back and prepared to give it to the scrap collector for recycling.

He picked up the third package.

When he opened the package, he glanced at the sender.

"Lu Ban? Is that the director?"

Xiao Wang immediately became interested, but soon he changed his mind and thought that there was no need for Lu Ban to send things in this way. If he wanted to give something, he could just call the professor directly.

Maybe it's an imposter, or someone with the same name.

He looked at the shipping address, which was indeed Jiangcheng. Confused, Xiao Wang opened the package, unwrapped the bubble wrap, and found a... wrench?

"What do we need a wrench for?"

Xiao Wang thought it must be a prank.

He was about to put the wrench back when he saw the note at the bottom of the box.

【Shell material】

"What?"

Xiao Wang was totally confused.

He looked at the wrench carefully again and suddenly felt that something was wrong.

If you say it is steel, it is too light, and if you say it is aluminum, the hardness is not quite the same.

Moreover, the metal flashes with blurred colors under the light, as if there is a colorful light brewing in it.

Staring at the wrench, Xiao Wang was stunned for a moment.

He thought about it and decided that it was better to believe it.

He got up and went to the chemical analysis laboratory.

"Brother Zhao, here is a material. Please help me analyze it and see what it is made of."

Xiao Wang handed the wrench to his senior in the same laboratory.

Brother Zhao originally thought that Xiao Wang had taken something, but when he looked over, he saw that he was handing over a wrench. He subconsciously wanted to curse, but the light from the wrench immediately attracted him.

Based on his many years of experience, most materials that can emit dazzling colors have complex ingredients.

He immediately took the wrench for analysis, and a week later, when the comprehensive analysis results came out, the entire laboratory was stunned.

According to spectral analysis, more than 70% of the elements that make up this wrench are currently undiscovered elements. The discovery of any one of these elements is enough to win the Nobel Prize.

Even the known elements on Earth present unprecedented combination structures. This wrench alone is enough to advance materials science by more than 50 years.

"Who found this?"

The professors couldn't help but ask.

Xiao Wang then remembered that he should go find Lu Ban to ask.

However, when he called Silent Media, the person who answered the phone said that Lu Ban was out collecting materials and was not at home for the time being.

"Going out to collect materials?"

Xiao Wang couldn't help but suspect that Lu Ban was going to get the materials for the wrench.
