Millions of insect corpses, and finally Lin Han collected 10,500 tons of high-strength metal.

These metals were collected by Lin Han into the system space, stacked high together, and looked like a mountain from a distance.

After cleaning up the battlefield, Lin Han asked Taichu to write down the coordinates and locations here, and then he began to return to the convoy.

At present, the convoy has marched to the border of Mongolia and is staying in place according to Lin Han's instructions.

The large number of insect mutant creatures in Mongolia really made Lin Han worry about their safety, so Lin Han had to personally escort them over.

There is not much distance to get here, and I believe that the convoy will be able to reach this location by this evening, and then tomorrow they will have to prepare to establish this base city of their own.

The process of welcoming the convoy did not encounter too many difficulties, although there were several waves of insect attacks along the way, but the number was not very large, and Lin Han did not make a move, but let other superpowers adapt to some of the fighting methods of the mutated creatures here.

At first, it was a bit thrilling, but after everyone got used to it, it began to become methodical.

Before sunset, the convoy finally reached the area three kilometers south of the Benchagan River.

When they arrived here, Lin Han arranged for everyone to set up camp, and have a good night's rest today, waiting for the establishment of the base city tomorrow.

To establish the work of the base city, Lin Han also planned to come alone, and his telekinesis could easily cut the earth and cut out an area of his ideal size. His idea was that the ground needed to be reinforced with metal, and that the all-metal layer of the ground would have to be ten meters thick.

In that case, he would need lots and lots of metal. Ten meters later, the entire area of the foundation had to reach 100 square kilometers, and the amount of metal needed was completely more than all of Lin Han's metal reserves.

But fortunately, he could collect metal, which was not difficult. And if he uses the metal he reserves, it is really a bit extravagant and wasteful, after all, it is a scarce high-strength metal.

The all-metal foundation is mainly to resist attacks from underground, and he will also lay some early warning devices inside the metal, which can be handed over to the original design. Then let the tech guys he brought with him take care of the production.

The outermost layer of the entire base city wall must also be metal, and attack weapons must be added inside, and ground-to-air weapons need to be installed on the city wall to ensure the safety of the base city.

All night, Lin Han thought about these things. When it was dawn the next day, he first reconnoitred the surrounding situation and made sure that there were no mutated creatures coming here to build a nest.

When it was dawn, everyone got up and had breakfast, and Lin Han asked Louise to gather the people.

Lin Han walked in front of the more than three hundred people with a smile on his face.

"Everyone, from today. We're about to settle down here. You are the first batch of residents recruited by my Lin Han, and all of them are elites from all walks of life, and I hope that with the joint efforts of everyone. We can create a better future! ”

Applause rang out.

Lin Han paused for a few seconds and continued: "When I finish building the outer wall of the base city, I will assign the work, and I hope you can do your best to complete it, because we are not safe here." ”

More than 300 people nodded in unison, loudly promising that they would do their best to complete their work.

Lin Han nodded with satisfaction. Immediately, he opened his arms, and the whole person slowly flew into the sky.

Mental power gushed out like a tidal wave. Lin Han let out a roar from his mouth, and his outstretched arms rose up.

"Up!"

'Boom Rumble~~~~~~~'

The earth trembled desperately. Immediately after that, a 10*10*10 volume clod of earth broke free from the constraints of the earth and floated. Then, more clods of earth floated one by one, and with the support of telekinesis, they flew into the distance and piled up one by one.

More and more clods of soil fell out of the ground and fell into the pile, and more than three hundred people in the distance widened their eyes, ordinary people were amazed at the strength of the superpowers, and the superpowers were amazed at the terrifying power of Lin Han's telekinesis.

Soon, a 100-square-kilometer stretch of land was cut out, all at a uniform depth of 20 meters.

In the middle of his thoughts, Lin Han exchanged a circle of Mithril the size of a water tank from the system space.

Mithril is a magical metal, such a metal does not exist in the ordinary world, so Lin Han exchanged some directly from Boss Wang, and the cost of spars is not much, after all, if you don't have magic ability, no amount of Mithril is useless.

Using his telekinesis to control Mithril, Lin Han spread out this ball of Mithril, forming a curtain of 100 square kilometers, and Mithril was just a thin layer, very thin.

However, this is enough, the strength of Mithril itself is not high, and Lin Han mainly uses it to depict magic spells.

These are all things that have been seen from books in the Harry Potter world before, and Lin Han is also trying it for the first time.

He took out a small piece of Mithril and tried to carve it on it.

Lin Han's portrayal speed was very slow and careful, depicting the magic lines little by little, and every stroke was quite serious.

It wasn't until the last stroke was completed that the entire Mithril shone with a dazzling white light, and Lin Han smiled with satisfaction.

Strong enough mental power, coupled with Lin Han's seriousness and rigor, allowed him to succeed in his first attempt, he put away this piece of Mithril, which was originally an extra part, it was prepared by Lin Han for experiments, he planned to wrap that piece of Mithril on the surface of his Edelman metal longsword for a while, so that it has some magical lethality.

After completing the experiment, Lin Han is about to move seriously.

It is much more difficult to depict magic spells on a 100-square-kilometer Mithril than on a 1-square-meter Mithril just now, not only because it consumes more mental power, but also because the progress is very slow.

It took four and a half hours, from 6:30 a.m. to 11 p.m., for Lin Han to finish carving the magic spell.

The moment the last stroke was completed, the entire 100 square kilometers of Mithril radiated a dazzling white light, which seemed to be able to wash away the evil in the hearts of the world, with an awe-inspiring and inviolable majesty.

Lin Han also let out a long sigh of relief, and then he controlled this piece of Mithril to fall slowly, and finally covered the outermost layer of the 20-meter-deep underground.

This is also what Lin Han decided after all kinds of careful consideration last night, ordinary metals, even metals of the strength of gold and titanium alloys, those insects can eat them, even if there is an early warning device installed in it, it will cause huge losses.

Lin Han didn't want to fill in those gnawed parts every time, so he thought about it for a while before he came up with the magic spell. (To be continued)
