In fact, as soon as Bai'er appeared, Zhang Nan saw that Bai'er's eyes were a little different, because his eyes always gave people a blurry feeling, which was obviously astigmatism. The eyes that were not concentrated must look more blurry, and when Bai'er looked at the steam train he made, Zhang Nan obviously saw that Bai'er was putting his whole face up, so Zhang Nan was very sure that Bai'er's eyes must have problems.

"You, how do you know that my eyes have eye disease?" Bai'er was a little surprised. Although everyone in the Mo family knew about it, Zhang Nan was just an outsider after all, and it was the first time he met. Zhang Nan said his eye disease with one word, which really surprised Bai'er.

"The Buddha said, you can't say it. I'll ask you if you bet or not. I'm sure there is something wrong with your trick." Zhang Nan said with a smile, shook his head and said.

"I don't believe it. My tricks are absolutely fine. If you say there is a problem, you can prove it to me." Bai'er still didn't believe that there would be problems with what she did.

"I don't believe it, right? OK. You can start this thing now and I will find the problem for you immediately." Zhang Nan smiled. However, although Zhang Nan said that, Zhang Nan was still a little confused in his heart. Although Zhang Nan was sure that there was a problem with this thing, it would take a little more to say whether he could find it.

Mo Zu also wanted to know the problem of this trick of not running fast, so he called Ada Er and said, "You two, go find some carbide."

Not long after, Ada and A Er each brought a bag of coal to Mo Zu.

Before Mo Zu could speak, Bai'er started stuffing coal into the machine by herself.

"No, don't you use something to lure the coal inside first? How do you ignite the fire after you stuff it all up? So much coal will definitely not be able to burn it." Zhang Nan looked at Bai Er who was constantly stuffing coal into the boiler and said with a strange look on his face. Didn't this steam engine come up with her? Why can't she even make a fire?

"You don't have to worry about it." Bai'er said viciously. After that, he continued to stuff coal into the boiler. Soon, the coal in the boiler was stuffed to the furnace entrance.

Bai'er saw that it was almost enough, so she ran to Mo Zu's room. Soon after, she took out a gourd, opened the gourd bottle, and Bai'er walked in the things inside the gourd.

Although Zhang Nan had never seen what oil crude oil looked like, when he saw the black, shiny and very viscous liquid, Zhang Nan quickly thought of oil.

"Oh, I said Bai'er, you don't have to spend so much money on this. It's so wasteful. You don't know how much effort I have been wasted on finding such pure tinea oil." Mo Zu said with regret.

Bai'er obviously ignored Mo Zu, but took out a fire note from her waist, and quickly poked the fire note on the coal that had been soaked in oil, and the fire immediately started to grow.

The ignition point of crude oil is not high, and the fire starts before the fire breaks even when it touches coal.

Seeing that the fire was born, Bai'er looked at Zhang Nan provocatively, and Zhang Nan had no choice but to ignore it.

Soon, the water in the water tank was heated to boiling, and steam continued to leak out of the gas tank. Zhang Nan saw this and knew in his heart that the problem with this thing was.

The gas tank of the steam engine must be well sealed, otherwise the steam will scatter before it can push the machine. Not to mention the power, it is already very difficult to activate this thing.

"Okay, I know the problem is there. If you listen to me to improve it, you can make sure that this trick can run fast." Zhang Nan arrived.

"Oh? Qingquan, you discovered the problem so quickly? Old man, I have been looking for everyone from the Mo Sect for a long time, but I didn't find the problem." Mo Zu obviously didn't expect Zhang Nan to discover the problem so quickly.

"Of course, this problem is actually very simple. The problem occurs on this gas tank. The steam engine relies on steam as the power, but the steam has long been scattered from the beginning of water boiling until it starts to work. The sealing of this gas tank is really poor, and the steam has run away, so it is normal for the machine to run fast." Zhang Nan arrived.

"This...but it took a long time to build this gas tank. This gas tank is the best that Bai'er can build. We really have no choice." Mo Zu spread his hands and said, obviously Mo Zu had tried his best.

"Oh? You can still make irons?" Zhang Nan didn't expect that a woman who looks soft and weak can actually make irons. Isn't it appropriate to make irons like Ada?

"Don't underestimate me, I can make irons, and my skills are the best in the Momen. For me, things made of iron are all my good friends." Bai'er said seriously.

"Oh, then congratulations, your friend was leaking." Zhang Nan said expressionlessly.

Obviously, Bai'er's seriousness did not bring about Zhang Nan's seriousness.

"You..." Bai'er was so angry that she didn't know what words to use to retort Zhang Nan.

"Okay, OK, Qingquan, don't joke with Bai'er anymore. Can you solve the problem of air leakage in the air tank like a way?" Mo Zu asked.

"Well, to be honest, I don't know much about ironwork, so I definitely can't do the improvement of ironwork technology." Zhang Nan spread his hands and had to tell the truth.

"Look, ancestor, I just said this person is definitely not good. If you ask him what he is doing, give me some time and let me solve this problem." Bai'er snorted softly.

"I can't?" Zhang Nan pointed to his nose with his finger. Zhang Nan now wanted to go up and pat Bai'er on the shoulder and told her that men can't say no.

So Zhang Nan put his hands on his chest and said, "Although I can't make a blacksmith, I can get a gas tank with good sealing. Unlike some people, if she waits for her to study the gas tank, I guess my hair will turn white."

"You..." Bai'er pointed to Zhang Nan with his hand, and was about to say something, but suddenly Bai'er thought of something and said, "Okay, didn't you say you could get a good gas tank? Then you can take out one and let me see. If it's really better than mine, then I won't say anything."

"If you can't get it out, hum." Bai'er came sarcastically.

"If it doesn't work, then what?" Zhang Nan asked back.

"If you can't, if you can't... I haven't thought about it yet." Bai'er finally didn't think about what to do if Zhang Nan couldn't do it.

"Okay, you don't have to waste your brain anymore. What I took out is definitely OK." Zhang Nan said.
