After thinking about it carefully this time, Chi Nan was really taken aback. He really didn't expect that these princes and princesses would actually infiltrate their power to this point.

Even the people on Rhamas's side can be divided into several factions. The first is the Imperial Army here, and there are definitely Imperial troops stationed in the border area. At the beginning, the three major legions were, and these legions were subordinate to the military and supported the Great Prince.

And the aristocratic groups led by the governor supported the second prince, which can be seen by looking at the words they wooed.

What Chi Nan didn't expect was that many of the caravans of Ruimas actually belonged to the second princess, and many of these caravans had joined the business alliance. There is also such a existence within his own business alliance. It's a pity that although they are only businessmen, they are too deeply involved in the business alliance, and when they find out, it is not easy to deal with.

Unless, Chi Nan has to risk offending most of the nobles, and he has to take on the name of going back on his word to clean them up. Besides, once they're cleaned up, there's no telling what they're going to do.

In the end, Chi Nan had no choice but to let people clean up the scope of his Hongsha Ridge and try to find out these existences that did not belong to him.

No one is courting herself on behalf of the Celestial Princess, but there are people who represent the Celestial Princess to discuss cooperation with her. This made Chi Nan understand that the eldest princess was not just looking at her own territory.

In other places, the power of Princess Celestia is also extraordinary. Before, there was no way to trade, but now with airships it's different. Chi Nan can only use a small number of airships, and temporarily needs to support the internal to delay. What the hell is this eldest princess thinking, Chi Nan really doesn't understand.

While thinking, Chi Nan remodeled his own tank. At this time, Hemila went to play with the other noble ladies, so only Romilia still played by her side.

Romigara doesn't seem to be as wary of herself as she used to be, otherwise Romilia wouldn't have just left Romigara's sight. In front of Chi Nan, a huge tank was slowly crawling.

This kind of slow speed made Chi Nan frown, and the motivation never went up.

Romelia, on the other hand, was bouncing around the tank, seemingly very interested in the big toy.

"Brother Lord, how does this thing move, I heard that it can also fire cannonballs, is it true? Romilia, who was looking around, still had time to go back and ask.

Chi Nan replied the same as before, and said with a flat and natural face: "Of course it can be launched, and it can also break the city wall." How do you say you moved? Of course, you use your legs to move. ”

"But where are the legs, aren't they wheels? Romilia's little head spun around with the wheels.

Chi Nan exhaled, it seems that it still can't work. With a single tap, a layer of wood shell next to the tank fell. "You see, that's how it moves, using the roots of the tree to push the gears, and then the wheels turn. ”

Chi Nan simply didn't continue to study, this power problem, he has been studying for a long time, unless he makes a steam engine, or finds a more dynamic plant, otherwise this is basically the end.

Romilia lay in Chi Nan's arms, her big purple eyes looking at the things moving inside. If you have a phobia of intensity, it may be very unbearable to see such a scene.

Suddenly, Romelia said curiously: "This thing has legs, why don't you just use your legs to walk, and you have to push the wheels with your legs, it's so stupid." Chi Nan's body stiffened suddenly.

"You, what did you just say?" Chi Nan felt a spiritual light pass through his eyes.

"I said stupid. Romilia's innocent eyes stared into Chi Nan's eyes.

"No, no, no, it's not this sentence, it's the one above. Chi Nan looked at Romelia very anxiously.

Romilia put her finger next to her mouth and tilted her little head to think, "I said, why don't you just walk on your legs, it seems like this sentence." Romelia said with a wink.

Chi Nan's eyes lit up, and he quickly kissed Romelia: "Great, this is it." ”

Romilia giggled and pushed Chi Nan's head away: "Brother Lord, it's so itchy." Romilia was very happy when she saw Chi Nan's smile.

"yes, my brother is so stupid, he didn't even think of this. Since you have legs, why not use them to walk. Chi Nan found himself in a misunderstanding.

I have never wanted to develop industry, but because of the relationship between the previous living environment, it is natural to want to imitate scientific and technological products, and this problem cannot be changed. While some things can be very useful to imitate technological artifacts, there are other things that are imitated and cause problems for themselves, like a tank.

These plant rhizomes don't have that much power, they are so short, and they have to be used to push gears, and it's strange that the tank can be so fast. If you use too much force, you may even break the gears.

However, how can plants and animals be the same as the products of science and technology, these are natural creatures. For nature, it's best to walk directly on your legs, rather than with a wheel or something.

Chi Nan put Romelia aside, and then the green light in his hand flashed, and a model of a wooden tank that was not too big slowly appeared. Only this time instead of tracks and wheels underneath, the legs are stretched out.

While thinking about it, this thing naturally grows like a kind of insect that he is familiar with, that is, spiders. Exactly eight legs, nimbly crawling around on the ground. Seeing this thing, Romilia immediately focused on this little thing, which in Romilia's opinion was a toy.

"The roots can't be that thick, so to make a leg that works, you have to weave and fuse it together. It seems that the position of this joint still has to refer to the structure of animals and welcome flowers. ”

Chi Nan muttered to himself while considering the bearing capacity of the plant's legs. "Then the tank can't be too big, otherwise it won't be able to run if it's too heavy, and it's easy to sink in. ”

"By the way, it's not big, so it looks like the shells have to continue to shrink, otherwise it will affect the ammunition load. For unmanned tanks, the bomb load is an important indicator of combat effectiveness. I am so clever that the air compressor can be adjusted to be a little larger to make the shells more powerful and penetrating. ”

After a problem is solved, the ideas in front of you are connected into a line, and there are more and more ideas.
