Passive defense is not as good as active attack, Lin Han only carved two magic spells on Mithril, one defensive and one attacking.

And once this place is attacked, as the portrayer of the spell, Lin Han will know it as soon as possible.

Of course, early warning devices still have to be installed, but this time not inside the metal, but outside.

Detect it early to respond effectively.

After laying this layer of Mithril, Lin Han put on his armor and left here.

Half an hour later, just as the others were enjoying lunchtime, Lin Han returned.

With a wave of his hand, a large pile of metal was taken out of the system space, and the dense metal fused together under the kneading of the telekinesis, and finally formed a whole.

Lin Han laid it layer by layer, and at the same time handed over the drawings that Taichu had already designed to Louise, and asked her to arrange scientific and technological personnel to be responsible for the production, and Lin Han had already prepared the materials according to Taichu's instructions.

The metal of the foundation, Lin Han changed his previous thoughts, and became a layer of metal and a layer of soil, the soil is not ordinary soil, but a high-strength soil layer formed after Lin Han's mental power is constantly squeezed.

Basically, a layer of 50 centimeters of metal and then a layer of 50 centimeters of earth, overlapping each other, covering the bottom ten meters.

Then Lin Han took out more metal and began to build the city wall.

The walls are truly all-metal, but hollow, with a variety of assault weapons and even armed men.

Lin Han connected the roots of the city wall to the foundation, and the four walls were eight meters wide, consuming all the metal that Lin Han had just dismantled from a nearby city.

After doing all this, Lin Han once again carved a magic spell on the inside of the city wall.

Because it's not Mithril. The effect of the spell is difficult to exert its full effect, but Lin Han himself does not portray any attack or defense, the effect of this magic spell is to conceal the aura.

First, it can protect the main station personnel within the city wall, and secondly, it is also to prevent those who can control metal or have the ability to control all things like Zhou Chen.

Magic spells can be effectively resisted for a while, but only for a while, of course. But at least it serves as an alert to them that there are people in the area who are trying to use the metal to attack them.

In the future, Lin Han will strive to go to some high demon worlds and learn some more powerful magic arrays to come back, so that he can truly protect his hard-built base city.

The walls were built, and the sky was already dark.

Lin Han let everyone enter the base city through the city gate on the north side.

He also hung a plaque on the top of the city gates on all sides, with three big characters written on it:

Metroidvania!

Hence the name. The main thing is that Lin Han has decided to form a team led by himself, and the current personnel of this team are, Louise, Gulatos and Enron.

More people will be added in the future, of course, Lin Han takes the elite route, and will never invite too many people to join his team.

He had already thought of the name of the team. It's called the Galactic League.

Well, Lin Han admits that he is a bit of an Avengers, but he thinks the name is pretty good anyway.

After inviting everyone into the city, Lin Han closed the city gates.

The 100-square-kilometre city is ...... Nothing.

However, the ground under his feet is silver-white metal, bright enough to be used as a mirror, and Lin Han also made the road in advance according to the plan made at the beginning, after all, the ground is too smooth to walk. Therefore, the real road of walking people is marked with anti-skid lines.

Looking at the city that could be seen at the other end of the city wall at a glance, Lin Han smiled and turned to look at the people behind him.

"Alright, from today. We are going to work hard for this metroidvania together, and I hope that in the near future, our metroidvania can truly resound throughout the galaxy. Lin Han said with a smile.

Others also mostly took this sentence as a joke, except for one person...... Gulatos.

Others may not understand how serious this disaster really was, but Gulatos does, because of his hometown. Already occupied by the evil spirits of time and space, he knew very well that this disaster would affect the entire galaxy and even more galaxies beyond the galaxy.

Lin Han's sentence that made the name of Metroidvania resound throughout the galaxy was just a joke in the eyes of others. But in Gulatos's heart, he felt that Lin Han was not joking. Instead, he was saying this very seriously.

Lin Han also saw their thoughts from everyone's faces, and he didn't explain, after all, he couldn't tell them that this disaster had affected the entire universe, right?

For many people, they may still have the confidence and motivation to fight against a catastrophe that will affect the entire earth, but if they know that this battle has already escalated to the level of the universe, I am afraid that they will suddenly feel hopeless.

Therefore, Lin Han did not intend to tell them this fact.

Many people shout all day long about the right to know, but when a cruel reality is really in front of people, in fact, what everyone hopes more is to be able to forget all this and still live happily, even if there are only the last days of life, at least they don't have to live in fear and nightmares even in the last few days.

The right to know should also be divided into situations, such as the current situation, Lin Han chose to hide this cruel fact.

On this night, everyone spent a happy night in the still deserted Metroidvania.

By the time dawn the next day, everyone got up and started working.

Lin Han was also busy again.

Today his mission is to travel around the world, dismantle some of his favorite buildings, and put them in his Metroidvania in their original form.

It was too much trouble to build the building by himself, so Lin Han figured it simple and fast, so he thought of this method.

There is no need to worry about the foundation at all, Lin Han directly moved the entire foundation of the building together.

What is madness?

Lin Han is really crazy when he does this.

The first thing he was worried about was some famous buildings in his motherland of China, those that were too big, he didn't care about it, anyway, the height was below 300 meters, and all the ones he liked were moved.

However, many buildings have been somewhat damaged or even directly destroyed, and in a situation like this, Lin Han has no choice but to give up and choose another one.

Running around one by one, looking at the high-rise buildings that kept appearing in the galaxy city, the more than 300 people were dumbfounded.

They've never seen a base built in this way.

And what is that? Isn't that the Eiffel Tower? This is not a fake, but it is a genuine product, which Lin Han moved directly from Paris.

Look over there, isn't that the Pearl of the Orient? I've moved this thing too!

This Oriental Pearl, but Lin Han took a lot of effort to move here, and the Oriental Pearl, which is more than 400 meters high, is really not good. (To be continued)
