Zhang Feng was made to laugh by the appearance of these three guys. There was no way. These three guys changed their faces too quickly. They were still dying in the last second. Now they surrendered. He couldn't help but give the three superficial guys a thumbs up: "uh huh, you have this awareness. After the successful transformation of the hot-air balloon, I promise to send you to heaven together."

Send us to heaven?

Chumo frowns.

That

It feels a little strange.

But there seems to be no problem with careful taste.

Hot air balloons are heaven.

After thinking fruitlessly, he showed a silly smile: "well, well, as long as it's Fengzi, you must listen."

"Yes, we must listen."

Chang sun Chong quickly agreed.

"In that case, gather around all of you."

Zhang Feng glanced at the crowd, then looked at Ma Zhou and said, "Ma Zhou, go and get me some salt water and start the experiment."

Ma Zhou was so fast that he brought salt water in less than a cigarette.

"Teacher, here comes the salt water."

He had a basin with a lot of crude salt in it.

Zhang Feng nodded, turned around, took a piece of cotton cloth, invaded all the cotton cloth into the salt water, took it out slowly after fully absorbing the salt water, then twisted the cotton cloth dry, put it aside, picked up the small iron jar, checked it, and began to wrap it after confirming that there was no problem.

"You all look carefully now. Although you can't use it, it's good to learn more knowledge."

He said to the crowd as he wrapped his bags. He didn't forget to impart knowledge. He was really tireless.

While talking, the cotton cloth had been wrapped on the small iron jar layer by layer until it was wrapped for three layers. Then the wrapped small iron jar was put into the big iron jar. All the preparations were finally completed. Smoke a cigarette to reward yourself.

Zhang Feng took out a cigarette from his waist, and the fire fold automatically handed it over. He turned his head and saw that it was Chang sun Chong. Since someone handed the fire, it was not polite. He stretched out the cigarette end, lit it, took a deep breath, took it in his hand, looked at Chang sun Chong and smiled: "you go and pour the coal into the big iron jar, and the small iron jar will also pour, remember?"

My parent sun Chong just handed over the fire. He had no choice but to wrong the boy.

Chumo doesn't talk nonsense. He nods like a chicken pecking rice. He quickly takes the coal and goes in. He doesn't give up until he is full.

"Teacher, what should I do now?"

Ma Zhou tilted his head and asked curiously.

Zhang Feng didn't answer. Instead, he looked at Chumo with a sly smile on his mouth: "go and put those two iron rods into the coal outside the small iron jar."

Chumo frowns with a foreboding feeling.

"Why did I go?"

He was dissatisfied and pointed to Ma Zhou: "didn't he ask just now? Why didn't you let him go?"

"If you go, you go. Where's so much nonsense?"

Zhang Feng raised his eyebrows and kicked Cheng Chumo's fart.

Chumo groaned a little wronged, but he went to get the iron rod as ordered. This guy was strong. He seemed to want to take all the anger Zhang Feng received from the iron rod and insert it with the iron rod until he heard the sound of carbon breaking.

"Teacher, this..."

Hao Chujun points to Chumo and looks at Zhang Feng. He is too anxious to speak for fear that the other party will destroy the experimental equipment.

Zhang Feng didn't care. He waved to show that there was nothing wrong, because he knew that the tighter the coal, the better, so that the resistance would be large. Moreover, in case of a call, the injury was not himself. Why are you so nervous.

Hao Chujun and Ma Zhou, as students, had no choice but to stand aside and watch. However, the sound of cat obstruction was heard all the time. It was really uncomfortable. They simply covered their ears and ignored the rampant killing in front of them.

After about a cigarette, Chumo stops. The coal is smashed. None of it is complete, and the iron rod is completely inserted. It looks good.

"How's it going? Am I doing ok?"

He wiped the sweat on his forehead and looked proud. He felt that he had completed all the experiments.

Zhang Feng skimmed his mouth and came forward to sweep it. It looked good, but he didn't know what happened to the voltage.

"Iron cow, touch your hand on two iron bars to see the effect."

He looks at Chumo with a malicious smile.

But Chumo is not stupid. He seems to see the truth and quickly waves: "I've done so much work just now. Should you change someone? Can't you hold on to one person? Even if it's a cow, you have to rest."

After that, he sat on the ground and looked like he didn't want to remember. He was not interested in the experiment. He just wanted to show off. Of course, he didn't remember to do such a thing now, let alone Feng Zi's smile just now. Eh, there would be no good thing if he thought about it.
