When the convoy returned, she encountered a complicated-looking thug at the entrance of Dongcheng. She should have a way to roughly determine what happened?

"I killed three mysterious people in the fourth sequence, one is the human demon cultivator, the other is the human sword cultivator, and the other is the standard demon. They are all superb, so I think we can cooperate."

Zhang Yang stepped forward and said straight to the point.

The Qiang Knight was not surprised too much, but just looked at Zhang Yang with pity, "If you are willing to enter the fourth sequence now, you will find out how naive you are, so don't think of dragging me into the water, and let me guess, is it because you can kill these three extraordinary people because you suppress them at all costs and at all costs. How much does it cost for this?"

"Indeed, you gave those who were surprised by the existence and won a big victory in this way, but you were like that. Do you want to replicate this way again?"

"So I'll advise you at the end, stop tossing. After 30 days, I will activate the Xianxia Village Building Task and automatically leave this world. I suggest you the same thing. You will never complete this doomsday village building task, because you stabbed the hornet's nest."

The breach rejected Zhang Yang's request for cooperation, and the reason for rejection was so confusing.

"What the hell is going on in the fourth sequence?"

Zhang Yang frowned. He originally thought he was facing the demon clan, but two human clans popped up. The secret hidden in it was terrible. If you were not careful, you would be afraid that the corpse would be gone.

"Then let's do the construction for the time being."

Zhang Yang smiled casually, he would not be scared by the saying of Qianggang, but it did not mean that he would take it lightly.

At least, the harvest he gained in the past few times was dozens or hundreds of times higher than the harvest he gained by staying still, just guarding a city.

As the saying goes, a man cannot be rich without wealth, and a horse cannot be fat without grass at night.

He still wants to continue leaving the city, but not now.

“Recruiting: 200 armed mercenaries.”

“Recruiting: 50 mechanical engineers.”

“Recruiting: 100 skilled workers.”

“Recruiting: 50 construction workers.”

Zhang Yang recruited 400 people in one go, of which 100 were the daily routine side mission progress, while the remaining 300 people were recruited by completing world-class side progress.

From this point, we can see the advantages of leaving the city. If you don’t leave the city, you will not trigger world-class side missions.

"Upgrade, upgrade 143 ordinary armed mercenaries to captain level."

"Upgrade, upgrade 46 ordinary mechanical engineers to captain level."

"Upgrade, upgrade 54 ordinary construction workers to captain level."

"Upgrade, upgrade 63 ordinary skilled workers to captain level."

Zhang Yang has begun to deal with internal affairs again. Over the past ten days, with the development of various affairs, the upgrading of these construction workers and technical workers is inevitable.

So to date, the basic information of his doomsday fortress has been very considerable.

Doomsday Village Building Order: White Quality.

The bounder of the village building order: Zhang Yang, the owner of the second-level war badge, (200/500), the function of the war badge, the upper limit of time and space travel +10.

Ongoing village building mission: 100 million demon corpses need to be killed, 298760/100000000.

Mission progress: On the tenth day, there is already a level 3 Doomsday Fortress, and the village construction order can recruit 12,459 people.

Population has been recruited: construction workers (350), including 75 construction captains. Technical workers (400), including 95 technical captains. Mechanical engineers (120), including 1 mecha driver and 46 team-level engineers. Armed mercenaries (583), including 19 mercenaries, 183 team-level mercenaries, and 381 ordinary mercenaries.

The technology tree that has been mastered: Level 3 Doomsday Base Vehicle, Level 3 Charge Charge, Bullet Reload (-10% Power), Bullet Production (-15% Power), Automatic Rifle Production (-20% Power), Heavy Machine Gun Production, Vehicle-mounted Dual Six-Pipe Heavy Machine Gun Production, 65mm Caliber Rifted Cannon Production, Thermal Power Plant, High Voltage Power Grid, CNC Machine Tool (Note, this city already has it)

The technology tree under pre-research: Level 4 Doomsday Base Vehicle, Level 4 Charge Charge, Armor-piercing Bullet, Armor-piercing Cannonball, Compound Defensive Armor, Communication Tower, Small Radar, Rapiercing Cannon, Tank Warrior.

"Well, the level 3 Doomsday Fortress is too weak, so you will have to level 5 Doomsday Fortress."

After studying for a while, Zhang Yang said to himself that he has indeed ignored the construction of the Doomsday Fortress these days. There is no way. There are only so many construction workers in total. Even if he has to work 17 hours a day, he cannot achieve such a fast construction speed.

"Check it out."

With a smile, Zhang Yang clicked on the Doomsday Village Construction Order and began to use energy to purchase six types of building facilities attached to the Doomsday Village Construction Order.

He chose a special reinforced concrete structure with a thickness of 120 cm and a steel mesh density of 6. If you buy it, 500 points of energy per cubic meter will be formed instantly.

In the past few days, Zhang Yang has accumulated a total of 1 billion points of energy from killing ordinary demon corpses, elite demon corpses, and special demon corpses.

So now it is really a slight idea to use these energy to build the main body of the level 5 Doomsday Fortress.

A few hours later, when all the energy in Zhang Yang's hand was emptied, the main body of the Level 5 Doomsday Fortress was basically completed, saving at least ten days. The remaining corners could be taken over by construction workers, including installing a defensive machine gun tower, etc.

It is worth mentioning that each upgrade of the Doomsday Fortress is not expanded on the original basis, but spread out layer by layer like cabbage.

Each level of Doomsday Fortress is a line of defense. The defense strength of this line of defense is the same. There is no level 5 Doomsday Fortress stronger than level 1 Doomsday Fortress, but the area is larger.

The only difference is the defense tower.

Because in the future, you may have to face millions of demon corpses, or even millions of demon corpses, relying on one line of defense to block the firepower network is too thin.

Therefore, we need to build a defensive tower.

Each defense tower will be equipped with 10 heavy machine guns or anti-aircraft machine guns.

Each defense line will build the maximum number of defensive towers as much as possible, thus ensuring that once the tide of demon corpses arrives, there will be a massacre of at least five firepower networks.

"This kind of tower defense game is quite fun, but if you don't go out of the city to grab resources, even the most fun tower defense game will collapse. One hundred million demon corpses, and the demon corpses that can be upgraded over time will really destroy everything like snowballs."

Zhang Yang sighed, and became more determined to continue hunting in the city.

But before that, he still needs to repair those damaged mechas.

With the expansion of the territory, the number of mechanical modification workshops has increased to five, which are divided into No. 1, No. 2, No. 3, No. 4 and No. 5.

The No. 1, No. 2 and No. 3 mechanical modification workshops are responsible for the pre-research base vehicles and charge tanks, and No. 4 is responsible for the processing of the weapon modification workshop.

Then the No. 5 Machinery Renovation Workshop was newly built, responsible for repairing and studying those damaged mechas.

This is the most important thing, so Zhang Yang mobilized 50 technical captains and 50 engineering corps captains in one breath, and transferred Li Dong to try to get the results as soon as possible.

"Boss, you'd better be mentally prepared. Through our current disassembly analysis, I can be sure that this is a machine that exceeds the current world's technological technology level in all aspects. Replication is impossible, and it is impossible within at least a year, let alone understand these technologies. So the only way at present is to disassemble all of these 24 mechas, select their intact parts, and then reassemble them. This is the fastest way for us to obtain a complete mecha."

Li Dong introduced to Zhang Yang that because of his talent and professional level, he is now the one who has the most say in these mechas, and the technical captains can only be his subordinates.

"How long will it take?"

"Three days."

"Okay, then I'll give you three days. In three days, I hope you can drive this mecha to fight." Zhang Yang made the decision, everything for combat effectiveness.

After leaving the machinery modification workshop, Zhang Yang immediately went to the weapon modification workshop. Here, all the captain-level mercenaries who had not yet strengthened their guns were there, a total of 113 people.

"Oh, it's like going bankrupt again."

After sighing in his heart, Zhang Yang took out 30,000 units of vanishing iron, 10,000 units of copper, and 1,000 units of silver.

These are enough to strengthen one hundred and thirteen firearms to the critical point.

He was detrimental. Although the captain-level mercenaries are not as strong as the king-level mercenaries, as long as the weapon is strengthened to the critical point, as long as the volley is launched, it will be very terrible to the lethality above the extraordinary.

"Actually, I can choose to give up the Doomsday Village Building task now. As long as I start the Xianxia Village Building task, it will automatically terminate. This is the characteristic of the Xianxia Village Building task. After all, I have 60,000 units of vanish iron, 30,000 units of vanish copper, 20,000 units of vanish silver, and 2,000 units of vanish gold. With so many materials, the overall value is no less than the rewards given to me by the Doomsday Village Building Order."

Zhang Yang sighed in his heart, he was spending 150 yuan to win a reward of 100 yuan, which was so depressed.

This is what the Qiugu mocked him before.

"Forget it, it's better to have a good start and end well, and I'm not at a loss now. As long as I kill a few more mysterious people in the fourth sequence, I might be able to get a set of Xuan-grade sword techniques, money, and clouds!"

After thinking about it over and over again, Zhang Yang finally decided to stay. Now he grabbed a bug, a bug about the fourth sequence. As long as he didn't want to know the secret of the fourth sequence, the Doomsday Village Building Order could only keep replacing and compensating him.

It’s nothing to compensate for one replacement once, but it’s different for several consecutive replacement compensation. This is a set of Xuan-grade sword techniques.

As a new sword cultivator who is determined to enter the world of fairy tales, there is no doubt how important a set of Xuan-grade sword techniques is to him.

"It's just that the risk is too great. If I leave the city next time, I will either not meet the mysterious people in the fourth sequence, or I may encounter several at once, so be fully prepared."
