While imagining the power of the new cannonballs across the battlefield, everyone didn't know how to express their expressions. On the one hand, it is because the weapon is too terrifying, and on the other hand, it is also excited.

With this kind of weapon in his own territory, he will definitely be far superior to any other territory in terms of combat effectiveness. But with this weapon, the situation on the battlefield has completely changed.

Thinking that they might have to face this weapon in the future, all the people were in awe.

Think about it again, with such a powerful weapon, what is the purpose of your hard cultivation. If there are a large number of weapons like this, not to mention that these black iron warriors who have worked hard to cultivate themselves are useless, even if they are bronze level warriors, it is a question of whether they can retreat under this kind of attack, it is really terrifying.

Could it be that the senior warriors will be completely removed from the frontal battlefield in the future, several guards glanced at each other, and they all saw the helplessness and admiration in each other's eyes.

But fortunately, he was originally a guard and protected the lord. In terms of protection, no matter how powerful these cannons are, they are definitely inferior to their warriors, and this is where their value is reflected.

"My lord, with these cannonballs, our strength will definitely be greatly improved, and those berserkers will definitely not be able to break through our Giant Wood City. It's just that we don't have enough pack horses. ”

"Pack horses? Is the price of pack horses going up again?"

"It's not a matter of price increases, but money can't buy them, and the current pack horses have either been booked by the major nobles, or have been hoarded by those merchants, and they want to wait for the price to continue to rise before selling. ”

It's really a bunch of profiteers, Chi Nan scolded in his heart, not realizing that he was also a profiteer, nor did he realize whose fault it was all about. Not its own pneumatic cannon, how could a pack horse have such a high price.

"Now the pack horses are not enough to arm our army in Hongshaling, and we don't have any of them here in Jumu City. ”

Chi Nan waved his hand: "The situation here in Jumu City is even more severe, you let someone go and inform one leg, he can leave one-third of our army's pack horses, and send the rest over for the time being." As for the problem of not having enough pack horses, I'll figure it out. "I was in a good mood just now, but I was ruined by this bad news.

The bald father nodded hurriedly, and Jumu City will be in charge of it in the future. Leaving with the others and letting people start collecting the shells here, Chi Nan left the place on his own.

Usually, while strengthening the city wall, I have time to study the problem of pneumatic cannons.

"With such a large cannon and no horse-drawn baggage, how can we achieve rapid transfer on the battlefield? There are cannons on the earth, too, and how do they move them? ”

"It's no different from a pack horse, and there's no car among the plants. And what is left...... Wait, tanks, yes, how did I forget about this king of land warfare. ”

Chi Nan's eyes suddenly lit up, since the earth can make tanks with industrial machinery, then why can't he make them from plants. It's just plants that need to move.

Wheels, tracks or something, just plant them yourself. Forget it, the tracks are not needed for the time being, so let's make the wheels thicker first. Under Chinan's control, a six-wheeled chassis was built.

"But how do you get the wheels to turn? "After fusing a pneumatic cannon with this chassis, Chi Nan found that there was no way to make this thing work, after all, it is impossible for a plant to grow into an engine.

"Since I can't, let the plant push it by itself, the plant has no legs, I seem to be able to make it." ”

Chi Nan thinks and makes at the same time. Next to the cannon, get out a lot of roots, these roots are the legs of plants. But this root has no point of focus, so it can't push the wheel.

After thinking about it for a long time, Chi Nan finally added a lot of gear-like things to the bearings linked by the two wheels. These are also small wheels, but the wheels are uneven. Then, a large number of fibrous roots were wound up and began to move. Pushed by Chinan, the root moves in one direction and finally turns the wheel.

For the first time, this man-made strange tank was running. "Stop. Chi Nan suddenly realized something, but the order was given a little late. This "tank" crashed into a tree at once.

No way, this new tank won't bend yet, it seems that a little more design will be added to make the tank bend. I'm not a person who learns mechanics, so I really don't understand these things.

However, for the powerful control ability of plants, Chi Nan can use strong means to add a design that can make the wheels turn to the plants. There are not many plants that can move, and if it weren't for the special rhizome structure of the rat trap, there really would be no way to make the plant so flexible.

Under Chinan's control, this large toy can finally move freely. Forward and backward and turning, the fastest speed is faster than the speed of a pack horse. And the barrel can be adjusted by itself, firing shells at any time.

Such a large tank, if all used to load shells, can hold more than 50 of them. This kind of bomb load, this kind of combat flexibility, far exceeds the average pneumatic gun.

"It's a pity that this tank can only move and launch when I am in control, and it can't be done without my control. Hey, when will we be able to let plants have some wisdom of their own? It doesn't matter how smart they are, they can fight according to the program just like in the game. Chi Nan sighed.

This tank looks good and powerful, but after all, it is only a prototype and an experimental product made by itself. With the plant materials and abilities that I have now, it is impossible to complete the design.

"Forget it, the model is also a model, design it first, maybe you will use it one day. Chi Nan simply no longer regards it as a subject for himself, but as a toy for himself when he has nothing to do.

With the careful carving and manufacturing of Chinan, this tank toy is getting better and better day by day, and the shape is getting closer and closer to the tank in the original memory. Even a lot of performance was forced to come out by Chi Nan using his own methods. Under the control of Chinan, when people see it, they will really think that this is a tank.

Perhaps because of the Great Migration, during this time, there were very few berserkers in this place. It's just that the other fortresses are not fully built, and Chi Nan is not allowed to leave Jumu City.
