After formally reaching an agreement with the Huaxia Alliance, the Dabei Tushan clan and Wenzai Bai Ze left Niu Hump.

Because their kingdom is still dominated by free trade, as long as the restrictions are lifted, then nothing will happen to them, and the owners of the property will decide for themselves.

The same is true for Li Qi, once he starts trading, the power of his alliance leader gradually decreases, according to the rules of the alliance, the alliance leader does not have much power to interfere in the trade of the owner, and only when the alliance is with the outside world, the power of the alliance leader will be unprecedentedly improved.

Actually, they don't need to care about anything, because they both need each other very much.

The highest record, in one day, the two sides have reached more than 100 cooperation.

It's pretty amazing.

Li Qi stayed in Niu Hump for a few days, more on behalf of the Huaxia tribe to negotiate with those large producers about cooperation matters, because the Huaxia tribe is not a free economy, but a social economy, this kind of large-scale cooperation, Li Qi has to talk about it personally, mainly around the kitchen, if not export industrial products, the Huaxia tribe will only have to engage in the food industry.

After reaching an agreement with Black Sheep Jiuzhen and them, Li Qi did not return to Cabinet Mountain, but returned to the Huaxia tribe.

He hadn't been back for a long time, and he had been staying in Cabinet Hill all the time.

But he did not go back to Washington directly, but went to Zhangguo Mountain first.

"Great Chief!"

"Great Chief!"

Li Qi, who was still in the air, was surrounded by a large number of Bi Fang, followed him, and landed in the central town of Zhanggu Mountain.

At this moment, Zhangguo Mountain has been lined with buildings, all kinds of strange-shaped buildings, between the buildings, it is lush and lush, very beautiful, Li Qi no longer knows the road.

"Great Chief!"

As soon as they landed, they saw Ershun and them coming over.

"You're in good spirits!"

Li Qi looked at Ear Shun and smiled.

Er Shun nodded again and again: "It's okay, it's okay." ”

"That's good." Li Qi nodded, and then admonished, "You must pay attention to your body." ”

He looked at Ershun's wrinkled face, and he was really a little worried, the current talent of Ershun was very important to him.

"Thank you for your concern, I'll pay attention."

Er Shun said and said, "Great Chief, please in the house, please in the house." ”

Li Qi followed Ershun to a large room, and the living room was very spacious and bright.

"What's going on?"

Li Qi suddenly frowned and said very dissatisfied.

Er Shun was surprised: "Big Chief, is there anything wrong?" ”

Li Qi said: "Why do you live so simply? This is outrageous. ”

Simple... Shabby?

Ear Shun raised his eyes and looked around, and then thought about the small cabin he used to live in, where was this shabby? But he immediately understood what Li Qi meant, and hurriedly said: "Great Chief, we are already very satisfied, we have never lived in such a big house. ”

"You can't say that." Li Qi waved his hand and said: "Life must be better and better, we must not be satisfied with the status quo, rest assured, I will let you live in a better house in the future." ”

"Thank you, Great Chief, thank you, Great Chief." Ear Shun is flattered.

But this kind of trick is a bit naïve for him.

Li Qi is only habitual to say this, saying this will not be offensive, just sat down, Li Qi couldn't wait to ask: "About the new fire fruit has been practiced for many days, I don't know how the situation is?" ”

Er Shun immediately said: "Great Chief, please rest assured, we are very cautious about the practice, and we have been observing, at present, only about five thousand Bi Fang have been consuming the New Fire Fruit, and no side effects have been found for the time being." ”

Li Qi breathed a sigh of relief when he heard this, and said with a smile: "I'm relieved, but I still have to be cautious, I have to wait until the death of Bi Fang, who has been eating new fire fruits, to be able to determine whether these new fire fruits have any side effects." ”

"I know, I know."

Er Shun nodded, and said: "But the Great Chief, the Guangxin Fire Fruit can't completely give Bi Fang freedom, after all, they still have to come back to eat the green water of Zhangguo Mountain, but the Great Chief doesn't have to worry, we are now developing a fire fruit that grows in green water, we hope that the fire fruit is born with the ingredient of green water, so that Bi Fang can be completely liberated." ”

Li Qi said: "It seems that I am really worried, you are much more careful than me!" ”

Speaking of this, he paused, and then said, "You should all know about the steam car. ”

Ear Shun nodded.

Li Qi smiled: "Then you should also understand why I asked you to find out the mystery of the fire fruit." ”

"Understood, understood."

Ershun suddenly stood up and said, "Great Chief, please wait a moment. ”

With that, he left the hall with the cane.

Don't....! Li Qi was overjoyed.

After a while, Er Shun returned to the hall with Zhu Xiang, only to see Er Shun holding a bottle made of peacock dung stone, while Zhu Xiang was holding a small brazier with some dry firewood in the basin.

Richie's eyes kept on the small iron bottle.

Wait until the cane township places the small brazier in the hall.

Ear Shun tried to pry open the stopper, only to see a shiny blue liquid coming from inside.

Li Qi faintly smelled a pungent smell, although it was not good, but he still twitched his nose a few times, as if he was enjoying it.

After pouring it, he took out a very short rope and threw it into the basin.

Whew.

A fire immediately ignited in the small brazier.

Li Qi stood up directly excitedly, walked directly to the brazier, looked down, and when he saw that blue liquid burning, his gaze was fanatical.

A strange light flashed in Ershun's eyes, and he said worriedly: "Great Chief, this... Is this the fuel you want? ”

"Nine out of nine yes."

Li Qi responded excitedly, and suddenly looked at Ershun and said, "This... How did you get this fuel? ”

Ershun opened his mouth, and suddenly stretched out his hand to the door, and said, "Great Chief, you come with me." ”

He led Li Qi to a large cave-shaped house, which was their laboratory.

I saw that there were long tables on both sides, on which were all kinds of bottles and cans, and there were some strange mechanical equipment in the middle, all of which were made of black iron, and were also equipped with some steam power.

There are rules for furnishings and everything, and it is a very formal laboratory.

This wasn't something that Richie designed for them.

What a talent! Li Qi couldn't help but sigh in his heart.

Er Shun first took Li Qi to a table, held a bottle and said, "Great Chief, this is the juice squeezed from the new fire fruit." ”

As he spoke, he picked up a very small bottle and said, "This is the unique green water of Zhanggu Mountain." After we dissected Bi Fang's corpse, we all thought that Bi Fang himself did not have all the elements that breathed fire, and Bi Fang, as a monophre-eating race, must have something to do with fire fruit and green water, and the Great Chief should think the same way. ”

Li Qi nodded and said, "But I found that the fire fruit and green water can't ignite." ”

"We've done a lot of experiments, and we've found nothing." Er Shun said: "Later, I thought, maybe Bi Fang doesn't have all the elements of fire, but they may have one or two of them, so we used Bi Fang's saliva to experiment, but we didn't get anything until ....... ”

He picked up another peculiar dry wooden box and said, "This contains the powder made from Bifang manure." ”

Oh, my God! Why is it feces again, can't you change the routine? Li Qi hummed with a strange face: "In other words, this secret is in Bi Fang's feces?" ”

Er Shun nodded and said, "We thought at the time that the dung was sent out in Bi Fang's body, and it must be mixed with the substances needed to breathe fire, but it didn't work out at that time, and it didn't work at all, which made me not make any progress for a long time, and we even thought that our previous speculations were wrong." It wasn't until one day, when I saw a tanuki beast slaughtering a pig on the side, and I saw that the pig's internal organs were still beating, that I thought that Bi Fang's air sac was moving, just like our stomach. ”

As he spoke, he walked over to a small piece of equipment, the main body of which was an oval, about twenty centimeters in diameter, very small, with a very delicate model of a steam engine on the side.

From this point, it is not difficult to see the talent of the beasts, as soon as the steam engine came out, they used it, they have a natural sense of these mechanical equipment, because they are short in stature, too weak in strength, they can not live without tools.

Li Qi said: "This equipment is made by you imitating Bi Fang's airbag. ”

Ershun nodded and said, "We also make the order of experiments according to Bi Fang's habits. Because Bi Fang can drink green water once every other time, the green water stays in Bi Fang's air sac for a long time, which means that this green water reacts with some substances in Bi Fang's body first, so we first fuse the green water with feces. ”

He said as he demonstrated himself.

"This amount is also formulated by us according to Bi Fang's eating and bowel movements." Ear Shun said again.

Li Qi nodded, thinking, I didn't expect that the experiments of this era were full of natural atmosphere!

"Add the fire juice at the end."

As he spoke, he poured the juice into the oval, and then said to Li Qi, "Great Chief, please take two steps back." ”

Li Qi subconsciously took two steps back, and then wondered: "Why?" ”

Er Shun said: "This device just simulates the principle of Bi Fang's fire, and it will breathe fire directly." ”

"Really?"

Richie took two more steps back.

Ear Shun smiled innocently, and then started the steam engine.

I could hear a few puffs of air.

I saw that the elliptical device swayed up and down from side to side, not very fast, but very regular.

It turns out that it takes shaking to be able to react, which I probably won't be able to think of for the rest of my life. Li Qi muttered to himself, if it was a study of dishes, he would definitely be able to think of this, but chemical experiments, he really couldn't think of it, he didn't have the talent for this.

After a while, I heard two sounds, and I saw a fire erupting from one end of the elliptical device.

Richie was amazed.

Er Shun explained: "Under this shaking, the juice and green water in it will react and become a gas with heat, and once this gas is exposed, it will burn immediately, in fact, Bi Fang spit out a gas, not fire, which is why Bi Fang must breathe fire, because when the gas in the air bag reaches a certain concentration, it must be released, but once the gas leaves the closed air bag, it will burn immediately, so it looks like it is breathing fire." ”

"I see."

Li Qi nodded, and said curiously: "That... And what about that blue liquid from before you? ”

Ear Shun said: "The blue liquid is because too much green water is added. ”

Li Qi was confused: "What do you mean? ”

Er Shun said: "Although we found out the secret of Bi Fang's fire-breathing, this gas is inconvenient to preserve, and it is even more inconvenient to use, we have tried many ways, but they have failed." Until one day, we learned from the chief of Nabifang that they must not eat too much green water, otherwise they will become ill and unable to breathe fire. We have previously proved that Bifang spews out gas, which means that too much green water, even if it is shaken, it will not produce gas. So we added too much green water, and after many experiments, we finally found a suitable recipe to add a certain amount of green water to ensure that it does not produce gas and can be ignited with fire. ”

"I see."

Li Qi nodded, looked at Ershun excitedly, and said, "This is really hard for you." ”

Er Shun said: "No, no, no, this is what we should do, we are very grateful to the Great Chief for winning an identity for us." ”

Li Qi laughed: "This is as it should be. ”

In fact, this fuel is the last step in Richie's plan, why he is so happy to give the mystery of the steam engine to the kingdom and other second-class races, it is not that he is generous, but he knows that this is just an excessive device, and he must make an internal combustion engine.
