The two of them looked at each other and were overjoyed. They quickly took the lead and led the way: "Teacher, this way please."
The onlookers took the initiative to make way. What came into view was a roll of coarse cloth, iron wire, brazier, coal and so on. However, the experimental equipment this time was somewhat different from the previous experimental equipment. This made Zhang Feng a little surprised.
He pointed at the experimental equipment in front of him and wondered: "Ma Zhou, Hao Chujun, why is the experimental equipment a little different this time?"
"Teacher, we found that the iron wire is more stable than the hemp rope, and it is not easy to be broken by fire, so we made some changes. Also, the brazier has been increased in weight, and the coarse cloth has been increased in thickness."
Ma Zhou cupped his hands and replied.
Hearing this, Zhang Feng stepped forward and touched the coarse cloth to check. Sure enough, as Ma Zhou said, the experimental equipment had been changed.
"Well, you can give it a try."
He glanced at the crowd and signaled to start.
Originally, he wanted them to improve the hot air balloon, so there should be some changes. There was no dissatisfaction in his heart.
"Yes, teacher.
Ma Zhou nodded. After he finished speaking, he called everyone to start preparing.
"You guys hold up the coarse cloth."
"You guys go and strengthen the rope."
After he finished speaking, Ma Zhou and Hao Chujun personally went to start the fire. Usually, when Zhang Feng was here, they did the experiment by themselves. This was an important experimental equipment, so there was no room for any carelessness.
The others busied themselves according to Ma Zhou's instructions.
Zhang Feng took out a cigarette from his waist and went to Ma Zhou and Hao Chujun's side. He picked up a piece of coal that had just turned red and lit the cigarette. He took a deep breath and smiled: "You two brats, now you are a lot more sensible."
It seemed that the reprimand in the morning had some effect. Otherwise, why would these two be so obedient? Why would they do everything by themselves?
"Teacher, you must be joking. Student is not setting a good example for junior brothers."
Ma Zhou scratched his head and showed a silly look.
Zhang Feng smiled and did not speak. He knew that these two guys humbly accepted the reprimand in the morning. He was about to comfort them when there was a roar not far away.
"Dean, everything is ready. Should we start the experiment now?"
Zhang Feng slowly turned his head to take a look. Sure enough, the coarse cloth had been propped up, and even the iron wire had been fixed. Everyone was very familiar with the process, because Ma Zhou had led them to experiment once before. This was the second time, so the operation speed was very fast.
"Okay, get the live pig over here and get ready to start."
Zhang Feng stood up and glanced at the crowd.
The experiment had to use live pigs, otherwise, the effect would not be achieved.
"Yes, teacher."
Ma Zhou cupped his hands and replied.
After saying that, he led the two men to pull the live pig.
Obviously, the live pig this time was much bigger than last time. It seemed that Ma Zhou and Hao Chujun had put in a lot of effort.
The live pig was quickly subdued and tied to the ground. Then, they hung the live pig and the brazier up. The coarse cloth was propped up as they waited for the wind to blow.
Zhang Feng put the cigarette in his mouth, looked up at the sky, and said to himself, "What can make the wind come?"
"Teacher, a gust of wind blew before we prepared to do the experiment. I believe the next gust of wind will come soon."
Ma Zhou put his hand in front of his forehead and looked like a monkey looking at the sea. He looked while answering Zhang Feng's question.
"Yes, teacher. Now that the equipment has been set up, we can only wait."
Hao Chujun narrowed his eyes. As he spoke, he intentionally or unintentionally glanced at the group of coolies behind him.
These students were invited by Ma Zhou and Hao Chujun. Last time, the two of them held the rope and it could be said that they were suffering, so this time, they thought of this method. It was a pity that these guys did not know the mystery. When they heard that they could participate in the Dean's flying experiment, each one was happier than the other.
Now, they were holding the iron wire, and their hands were sore. Only they knew how uncomfortable it was. Finally, one of them could not stand it and said with a constipated face, "Dean, what wind is this? I can't stand it anymore. "
The person who spoke was Pi Hou, who was hung up on the tree last time. He did not see the spectacular sight of the hot air balloon with his own eyes last time. He was a little unwilling, so he followed. He did not expect the iron wire to be so heavy.
Zhang Feng took out the cigarette in his hand and glanced back, "How would I know? Ask the person who dragged you here. "
He very naturally threw the question to the pot. He was really smart. He was secretly happy.
It was not that he did not want to say it, but he was not a god. How could he control the air?
Pi Hou saw that his questioning was fruitless, so he turned his gaze to Ma Zhou and Hao Chujun. He looked troubled, "Seniors, we can't stand it anymore. Can you put it down first?"
After saying that, Pi Hou prepared to put the iron wire in his hand on the ground.
Seeing this, Hao Chujun's face changed. He hurriedly went up, "Don't, please don't. What if the wind picks up as soon as you put it down?"
Now that he was in front of his teacher, he did not dare to mess things up.
Pi Hou was a little embarrassed. Putting it down was not right, but not putting it down was not right either. "Then what do you think we should do? In any case, I can't lift it up. "
"Come, come, come. Give me the iron wire. I'll hold it."
Hao Chujun took the iron wire and prepared to take it.
