"I've seen the lord, my subordinates didn't take a good look at Jumu City, it's a dereliction of duty on my subordinates, please condemn your lordship. ”

As soon as they met, Dad knelt down on one knee, his face full of frustration and loss. Chi Nan didn't care either, and stepped forward to help him up with both hands: "You did a very good job, I'm afraid it's not as good as you if you were someone else, and the city is not lost, what a crime." ”

Without waiting for the bald father to speak, Chi Nan spoke: "This time I came to solve this problem, if my idea succeeds, then these bugs will not be a cause for concern in the future." ”

Hearing this, the bald father's eyes lit up, and his lord would not talk nonsense: "My lord, what is the way to have such an effect." "It's incredible. There are a lot of these insects, and they are all over the place, and they can't be killed.

"Well, I just have an idea, and I haven't tested it yet. But anyway, let's renovate Giant Wood City first. Also, our airship has arrived, and the Spider Tank will arrive later. ”

"I want to open up an area here dedicated to growing spider tanks and airships, and when the time comes, some nature mages will be stationed here, as long as there is enough strength, the giant wood city will not be damaged. ”

Although the bald father was a little confused, he still nodded to show that he understood. As a subordinate, being able to follow Chi Nan with his current status and strength, the bald father is no longer satisfied.

After introducing Orna and asking them to temporarily cooperate in cleaning up those beetles, Chi Nan began to transform the giant wood city.

In the past, a layer of hardwood had been built into a wall from the cornerstone, but now to be strengthened, the area has been re-enhanced with a layer of diamond wood. And the previous cannons were also eliminated one by one and replaced with fully automatic ones.

The neural brain on the bald father is the main controller, and many other soldiers and officers also have neuro-brain links in their hands, and Chi Nan has already built this place as a military region. These neural brains alone took Chi Nan a whole day to make.

The installation was left to the half-elf nature mages who came together. At the same time, the area where the Spider Tank, the Airship, and the Stamina Beans are planted to sprout seeds and spawn them by the Nature Mage. These half-elves aren't here all the time, but rotate every once in a while.

Anyway there is an airship, which is very convenient. After reaching the silver level, it is much faster than before to transform the city and grow plants. Coupled with the help of the Nature Mage, it was largely done before the Spider Tank arrived.

The entire Giant Wood City has now been completely transformed into an intelligent giant city fortress. There are all kinds of pneumatic cannons around, and when encountering an enemy, the plant brain will distinguish the enemy type, and then automatically select the corresponding type of cannonball for a targeted attack. Through the plant brain, you can feel that aiming is much more accurate than that of a soldier.

Even in the event of a big war, the plant brain has no way to control the details, and those soldiers who use the nerve brain can control the corresponding cannon to attack.

For this reason, Chi Nan's group of neurobrains has added a new rule. That is, an ordinary soldier stands on the face of the cannon, and after verifying his identity, he intelligently controls this plant weapon.

Each control is temporary, and the next time it needs to be revalidated. In this way, the soldier does not have to choose a cannon and can only control this one, avoiding wasted time and some confusion.

This method was conceived by Chi Nan on the airship before he came here because of some confusion he encountered before. Now it's easy to get rid of it. Of course, the shells in this place are mainly beetle poison shells. Because only beetle poison bombs can create enough damage to those beetles.

Just because he was worried that the beetle poison shells would be cracked by the power behind those bugs, there were also a lot of various other shells that Chi Nan had prepared here. With intelligent network control, the work of the soldiers is much reduced.

In normal times, the soldiers are basically exercising and improving their strength, but now Chi Nan has popularized the cross sword technique to the entire army in Hongshaling, and every soldier can get the cultivation method of the cross sword technique.

And the civilians here are busier than before. Because the matter of transporting the shells to the corresponding ammunition silos was handed over to these civilians. As long as there is enough ammunition, even if the beetle is increased several times, don't think about breaking the defenses of Giant Wood City.

Looking at the mountains on both sides, although the beetles were not able to climb the mountain for the time being, Chi Nan still used this place as one of the main lines of defense. Use the wind cannon to break some cover positions, and the defenses on both sides are not weak.

The moat cannon was remodeled by Chinan, and the main body is a large rat trap, and the wind cannon grows in the bud of the head of the rat trap. When used, the wind element will be condensed inside the flower bud.

When the condensation is completed, the bud opens its mouth, and a wind cannon attacks out. The bud itself has become a layer of protection for the body of the cannon. In order to fully protect it, Chi Nan also added a layer of adamantium wood scales around the large rat trap grass. Even a silver-level warrior would have a hard time destroying these wind cannons with a single blow.

Because of the activity ability of the rat trap, the coverage area of these cannons is very large, with a total of 360 degrees, and they can even be attacked in the air or around themselves.

These cannons, Chi Nan connected them to the city wall, there were many above and below the city wall, and the watchtower and arrow tower were also transformed, all of them were this kind of thing, and the entire giant wooden city was once again armed to the teeth.

"This kind of defense, even a gold-level master doesn't want to approach at will. If this can still be breached, then it really deserves it. Chi Nan thought as he looked at the airships flying in the air, as well as the spider tanks that had climbed to the mountains on both sides.

"It's just a pity that the carcasses of those beetles are basically useless. "After Chinan's experiment, the carcass of the beetle cannot be eaten because it is poisonous inside. The whole beetle, only a layer of hard shell, is still a little useful.

But this layer of hard shell is at most about the same as its own red sand steel, and it is far worse than the blood cloud steel. And it is very heavy, and the freight of transporting it back to sell it is not low, and it can only be burned in the end. Only part of it is left, and when the supplies are delivered, they are delivered by the way, and go back and see if anyone likes it.

These beetle hard shells, sent back, are basically bought as a kind of collectible.
