The metal walls with painted black are constructed.

Lin Tian felt a little small when he stood at the foot of this tall metal wall.

The Earth descenders and the indigenous people who were watching behind were surprised by the towering city walls that appeared in dozens of seconds. Although they were mentally prepared before, most of them were in a daze at this moment.

A few dozen seconds later, a first Earth descended first, reacted and cheered, "Wow!".

Then, more and more people shouted excitedly and cheered.

With this twenty-meter-high metal city wall, living in this crisis-ridden continent of gods and demons, the arrival of the earth finally felt a little safe.

Lin Tian began to issue orders:

"Twenty high-level crossbow rattles were transported to the city wall, with the turret position!"

"Bound arrows, bows and arrows are sent to the small towers on the city wall to pile up."

"The archers team, go up to the city wall, and be familiar with the metal wall environment."

"Big pots, oil, wood, etc. are transported to the city wall near the outside. The blacksmith immediately rushed to create a large shelf suitable for burning on the city wall, which can rotate and pour hot oil into the outer city wall."

"The warrior prepares shields and long swords, spear-like weapons."

"Tonight, prepare to stand on the metal wall to guard the Spiderman."

….

Lin Tian activated his laboratory skills and super acceleration time again.

[Made a flamethrower fuel tank (can be injected 3 times, each time lasts for 3 minutes, and the effective range is 100 meters): It takes 12 hours to manufacture. Required resources: Ore: 0.5 units. Wood: 0.5 units. Yellow sand: 0.5 units. Crystal: 5 red grade 2 crystals. Is it research and development and manufacture: Yes/No?]

"Made 18 flamethrower fuel tanks." Lin Tian immediately chose to manufacture.

The flamethrower has been developed before, so the fuel tank can be manufactured directly this time, and there is no need for research and development time.

As expected by the Earth Special Command, if only fuel tanks are made, the time will be reduced by half.

The yellow light flashed in Lin Tian's hands. After the supplies disappeared, 18 metal fuel tanks appeared beside Lin Tian.

Lin Tian checked his super acceleration time, and there were only 38 days left.

Alas, three years of super acceleration time seemed to be quite a lot before, but it was really not enough.

It took two and a half years to build a small skeleton nuclear bomb.

Recently, I have created some weapons and fragmented items, and after building the metal wall, I have only more than a month of super acceleration time left.

You must upgrade to level 60 as soon as possible, upgrade your special laboratory skills, and obtain more laboratory super acceleration time.

Lin Tian took out the flamethrower he had used and showed him how to replace the fuel tank to Lan Liu and other members of the guard beside him.

One person has two fuel tanks, first equipped with one can, and the other can is placed in the storage space.

Lan Liu, the eight members of the personal guards, were now extremely excited to look at the fuel tanks piled up in front of them, and carefully took out their flamethrowers that were like magical artifacts.

They watched the movements of Chief Lin Tian carefully and then replaced the fuel from their flamethrower.

Each person gets two cans of flamethrowers, which can release six hundred-meter-long flames, each time for three minutes.

It is equivalent to these semi-professional archers, who can release six advanced fire dragon magic.

Tonight, guarding the camp to fight against the Spider-Man invasion, they have hope of upgrading and becoming stronger.

Following Leader Lin Tian, ​​it’s true!

Five transfer tutors began to arrange combatants and non-combat elderly and children in the camp in accordance with the orders given by Lin Tian.

The thousands of people in the Demon Cursed Camp were soon busy.

Many combat professionals first climb up the towering metal wall and feel the scenery standing on the wall.

Lin Tian also climbed the metal wall to feel like such a huge thing he had built for the first time.

The ladders inside the metal city wall and the ten-meter-wide panels on the metal city wall give Lin Tian a feeling, which is somewhat similar to the feeling of stepping on the concrete of the building.

The materials of this metal wall are not all metal. The metal fortress designed by many top scientific researchers and engineers on the earth are also well done in terms of details.

The panels of non-metallic materials on the city wall are to prevent the existence of demons and monsters that can release lightning and lightning. Once attacking the camp, it may cause large-scale damage to the defenders standing on the city wall.

Therefore, the upper panels on the city wall and the stairs behind were changed to insulating materials with different conductivity and non-combustible insulation.

In addition, there are also multiple lightning protection and conduction systems on the metal city wall.

In the later stage, this metal city wall can also be equipped with weapons, power systems, etc., leaving many interfaces.

There is also a small tower every once in a distance, similar to a bunker.

Even those who guard on rainy days can stand guard or rest in the tower.

When foreign enemies attack, long-range troops standing in the tower can gain greater protection.

Lin Tian walked on the metal city wall with eight members of the personal guard for more than ten minutes.

Lin Tian is quite satisfied with the metal city wall created by the drawings provided by the Earth Special Command. Although it consumes more resources, it looks great value for money.

At this moment, non-combatants in the camp have already begun to carry metal racks, crossbow arrows, feather arrows and other supplies to the metal city walls.

The indigenous people set up ropes on the metal city wall and transported large pots and barrels of oil to the city wall.

The fat uncle Jet also walked with Lin Tian, ​​looking around, and from time to time he pointed his fat head.

"Jet, I'm still at level 9 and I'm going to level 60. At that time, I can make a transfer. Is there anything I can learn the skills of a mechanic and mage in the 1-turn transfer system?" Lin Tian turned his head and asked the indigenous mentor of his profession.

Lin Tian is not very clear about the professional system of the God and Demon Continent after 1 turn.

But in recent battles, Lin Tian found that the mage professional leveling speed was faster in the later stage. If a high-level fire dragon magic continues, it will cause group injuries.

The mechanic's skills are also good, and it can enable you to create earth-based technology weapons in the Gods and Demons Continent faster.

Of course, the survival ability of mechanics to directly participate in combat is a bit too weak.

However, in comparison, Lin Tian is more inclined to obtain the skills of a mechanic.

Although I already have special laboratory skills, I may be able to transfer to the 1st transfer thief of the mechanic category and learn more special mechanic skills.

Lin Tian doesn't understand the skills of mechanics in this God and Demon Continent.

After hearing this, Uncle Jeter looked thoughtful.

After a few seconds, Uncle Jet spoke, "Chief, there are actually few mechanic professions. Thieves can transfer to mechanics and promote the promotion system, but... I don't know much."

After saying this, the fat uncle Jeter laughed dryly, raised his fat hand with a little embarrassed look and scratched his head.

Lin Tian glared at Jet. This thief changed his job as a mentor, Jet was too unemployed.

Fortunately, Uncle Jeter continued, "Captain Lin Tian, ​​the former leader of our camp, Elena, after obtaining the death of the rebellious mechanic and those mechanical legs, he sent a thief to the nearest human city, Sky City. I have contacted the thief profession before using a scroll. The message I received was that in the near future, Sky City will send a mechanic transfer tutor who will be transferred to our camp. At that time, you can ask the mechanic instructor, who should be able to give better suggestions."

After hearing this, Lin Tian also remembered this.

As soon as he arrived in the Gods and Demon Continent, on March 2, he completed the mission of finding a mechanic and handed over the mechanical legs of the mechanics who rebeled from the human camp.

It's already the evening of March 7th, and more than five days have passed. Why hasn't a new mechanic transferred tutor sent here in the main city of humanity?

This human main city is too slow to work.

"When is expected that the mechanic's transfer tutor will arrive at our camp?" Lin Tian asked Jet.

Jeter doesn't know either!

In front of Lin Tian, ​​the fat uncle Jet took out his communication scroll and spent the crystal to start it up to communicate with the indigenous senior thief pros who were sent to the Sky City, the main city of mankind several days ago.

A few minutes later, the other side replied.

"At the fastest tomorrow, three days later, the mechanics transferred from the main city will arrive at our camp. The mechanics who come to our camp have been assigned to the Sky City. At that time, they will be on a crystal-powered airship and escorted by senior mages and warriors. However, the escorted team of senior professionals will not stay in our camp for too long. I guess they will stay for dozens of minutes after coming and will return before dark." Uncle Jet reported to Lin Tian.

After hearing this, Lin Tian realized that the sky city of the main city of the Gods and Demons, there were airships.

The airship with crystal as a power source can obviously transport people to quickly.

But with airships, why don’t you send mechanics here earlier?

"Let the mechanic go to set off tonight." Lin Tian said.

After hearing this, Uncle Jeter looked puzzled, "Unless an emergency situation, the airship will not take off at night."

Lin Tian wanted to try to urge him again, but Colonel Liu's voice came from the Bluetooth headset.

Strategic analysts at the Earth Special Command have analyzed the reasons why the mechanic has not arrived yet based on known information and Jeter's expression and reaction.

[No need to urge, useless. I think the reason why I arranged for the mechanic to change jobs to the camp tomorrow is to worry about the safety of the demon curse camp where you are. After all, the magic defense barrier in your camp will be repaired tomorrow. Before the magic defense barrier in the camp is repaired, it can block the attack of demon monsters in the wild, so the sky will be relieved to send mechanic to the mechanic to the camp. The number of senior mechanics is rare, and the human camp of the God and Demon Continent will not send mechanic to the camp that is obviously very dangerous.]

Lin Tian was a little angry after hearing Liu Jiao's analysis.

Lin Tian thought about it, although the truth is probably true.

But the people on earth were summoned and forced to fight on the continent of Gods and Demons, and many people who came on the earth were in danger every day.

This human main city of the God and Demon Continent is actually afraid of sacrificing their senior mechanics!

This is a bit annoying!

Lin Tian was so angry.

Humph, after solving the survival crisis in the camp and defeating the demons and monsters, then settle accounts with the human main city of the God and Demon Continent.
