Lin Tian agreed to Reina's proposal and began to issue orders to allow mechanics in the city to immediately repair the metal wall.

The crystals and resources consumed during the repair of the metal wall are provided by the Demon Curse Camp.

In the Metal Fortress, many mechanics and Earth Arrivals began to stand in the towering metal walls and activate their mechanics' maintenance skills.

These people do not have the skills to build this huge metal wall, but only repair and maintain the skills they have can still do.

With the addition of many mechanic professions, the metal walls damaged by demons and monsters began to recover quickly.

The demons and monsters outside were still trying to attack the metal city wall, but after the monsters and demons fought for more than ten minutes, they found that the recovery speed of the towering metal city wall was faster than that of their destruction.

The monsters gathered outside the city could only temporarily give up destroying the metal walls, and many monsters howled outside the city.

The monster with flying ability begins to try to fly into the metal fortress.

Archers and mages, shooting these enemies from the air on the walls.

Now there are enough magic recovery potion tubes in the Metal Fortress. Each mage is like a moving turret that is constantly firing. Its combat effectiveness on the battlefield is several times higher than before.

Lin Tian looked at the display screen of his metal tower main control room and shot many pictures.

Fortunately, I built this metal fortress myself and lived on the ground floor. The surface of the earth is also metal buildings. Even if monsters fly above the metal fortress, they will not be able to cause effective damage to the people in the city in a short period of time.

The ground height of the inner city of Metal Fortress is more than two meters, and there are many facilities similar to small canopies.

This is when the inner city of Metal Fortress was first constructed, it considered the defense method to deal with the attacks of air demons and monsters.

Under this small canopy similar to tempered glass, people standing on the ground can avoid most attacks from the air.

The monsters gathered outside were a little too anxious to wait, and found that after flying into the metal fortress, the human base did not destroy.

Humans stood on the metal wall and were constantly firing feather arrows and magic.

Because the power grid on the high metal wall is released intermittently. Demons and monsters began to try to jump quickly outside the metal wall, trying to jump into the wall.

As long as the speed is fast enough and the time is right, there is really hope to avoid the attacks from the power grid and jump into the metal fortress.

Some demons and monsters with ranged abilities began to try to shoot against the humans guarding the walls under the city walls.

The guards in the camp suffered casualties one after another, and Lin Tian began to mobilize some soldiers to go up to the city wall to help defend.

However, the number of casualties continues to increase.

The energy supply speed of nuclear-powered generator sets in metal fortresses is somewhat unable to keep up.

Now, whether it is the power grid or the electromagnetic pulse main gun, the camp relies on this nuclear-powered generator set.

In recent times of fighting, the electromagnetic pulse main gun of the metal fortress was fired several times a day, and almost no excess energy was accumulated.

Lin Tian wanted to increase the startup frequency of the power grid on the city wall, but he couldn't do it, and there was not enough energy.

The only 19-day super acceleration time is not enough, so a second nuclear-powered generator set cannot be created.

Even if you invest a lot of crystals to accelerate, it is too different.

Lin Tian thought of a solution. Before it was dark, he couldn't hold his metal fortress anymore.

Once dark, the strength of the demons and monsters will increase, and they will not be able to defend themselves.

Many analysts from the Earth Special Command previously should have estimated that based on the scenes taken back by the super mobile phone, millions of warriors need to fight against demons and monsters outside the city to be able to defend them.

Now these people were released back into the city by Lin Tian and left using the magic teleportation array, and the metal fortress became even more difficult to let go.

"By the way, I'll try it with the mechanical superbody skills to increase the power of the metal fortress. The metal fortress is also considered a mechanical and technological item, just a little bigger." Lin Tian suddenly thought of a solution and muttered to himself.

At the Earth Special Command, when I heard Lin Tian’s words, I quickly analyzed it and felt that it was really feasible and there was a high chance of success.

Lin Tian checked his introduction to his mechanical super-body skills.

Active skill: You can bless a mechanical item or weapon at close range to increase its power for a short time. Each use consumes 100 points of mental energy. The duration is proportional to the power enhancement effect and mental power attributes.

Warm reminder: Machinery also has life, please feel about machinery.

(After master level 6, super body skills can be superimposed twice, and the amplification will be increased twice in a short time for a single mechanical item or weapon)

This skill can also be used in one span.

[Lin Tian, ​​sitting on the command chair of the metal tower, tried to use the mechanical super-body amplification real metal fortress to increase the power of the nuclear power generator set first.] Liu Jiao's voice appeared in Lin Tian's Bluetooth headset.

Lin Tian walked over quickly, sat on the control chair, activated his mechanical super-body skill, and tried to sense the metal fortress.

As the skill was activated, Lin Tian instantly felt that he had completed some kind of connection with the metal fortress, and he was the metal fortress.

Mechanical superbody skills superposition.

Lin Tian activated the mechanical super-body skill again.

After the two mechanical superbody skills were superimposed on each other, Lin Tian felt that he could override everything in the metal fortress. This metal requirement was like there were many living organisms inside.

What are these small living organisms telling Lin Tian again!

The sound was too small and too noisy, and Lin Tian couldn't hear it clearly.

It is also possible that they are not speaking words at all, but the transmission of some kind of energy.

"The power of the nuclear power generator unit increases. When it moves, I need more energy!" Lin Tian thought silently.

After this awareness emerged, the nuclear power generator set on the second floor of the underground began to operate at an ultra-high speed, operating against common sense, without any signs of wear and tear.

The energy was quickly converted, and Lin Tian began to try to quickly transfer this energy to the power grid at the high metal wall.

Now using the mechanical superbody skill, Lin Tian is connected to the metal fortress. After closing his eyes, he can see everything inside and outside the fortress.

Just like having a God's perspective, you can quickly change the area where the metal fortress is in.

This should be done by the fortress’s own monitoring and radar equipment.

The blue light flashed on the metal high wall. Some monsters and demons who tried to jump onto the metal city wall were just glad that they found the starting frequency of the metal high wall power grid and could jump onto the city wall staggered.

As a result, the starting frequency of the power grid on the metal city wall changed rapidly under Lin Tian's control, and the release time was also extended.
Chapter completed!
