"Since you two have understood, then go and prepare some coal, iron basins, basins, coarse cloth, live pigs, and thick ropes. I will teach you how to make a heat conduction device. When you are ready, wait for me at the sports ground."
Zhang Feng smiled with satisfaction and waved to the two. When he was about to turn and walk to the sports ground, he suddenly thought of something and turned to look at the two. "By the way, the pig must be more than 100 pounds, or else it won't work."
After that, he turned and walked to the sports ground.
Live pigs?
More than 100 pounds?
Ma Zhou and Hao Chujun were confused.
They could understand other things, but what was with a live pig?
Could it be that their benefactor wanted to eat pork? Then he didn't need to kill the pig on the sports ground.
Although they didn't know what their benefactor wanted to do, they always thought that their benefactor was right.
Their benefactor asked them to touch the iron wire for their own good. Hao Chujun didn't have the good fortune to remember this experiment forever.
Ma Zhou glanced at Hao Chujun, and then went to prepare the materials.
Hao Chujun was like a monk. He didn't know what was going on, but he also went to prepare.
After a while, the two came to the sports ground with the live pig.
This scene attracted the attention of a group of students. They frowned and looked at them with puzzled expressions. They were just short of saying that they were a disgrace to the educated.
"Benefactor, we have brought the materials. And this live pig, how do you want to kill it?"
Ma Zhou put the rope and other things on the ground and looked at Zhang Feng, panting.
How to kill it?
Zhang Feng curled his lips.
So these two guys thought that he wanted to eat pork?
"Who said we want to kill it? Tie the pig up. We will use it for the experiment later. "
He rolled his eyes at the two of them.
The two of them heard the dissatisfaction in Zhang Feng's tone. They quickly pulled the pig and tied it up.
"You two put the coal into the iron basin, then ignite it and tie the rope."
Zhang Feng glanced at the two of them and said with a smile.
The two of them didn't suspect anything and quickly followed Zhang Feng's instructions.
Ma Zhou had experience in burning coal before, so he did it quickly and ignited the fire in a moment.
"Benefactor, the fire has been lit. What should we do now?"
Ma Zhou squatted on the ground and looked up at Zhang Feng.
"Now, hold up the cloth and place it above the brazier. Then, hang the pig under the brazier and see if the cloth can rise."
Zhang Feng looked up at the sky, a little worried.
In fact, this was the only way he could think of right now.
Without any other materials, he could only use coarse cloth and hemp rope as a substitute.
Ma Zhou nodded his head and hurriedly tied the pig under the brazier. The coarse cloth had also been tied. Now, he was waiting for his benefactor to tell him to fly.
The two of them held on to the rope, trying not to let it get burned by the fire.
Unfortunately, the coarse cloth didn't move at all. It didn't even move. If it weren't for the two of them supporting it, it would have been burned away long ago.
"Benefactor, when can this coarse cloth fly?"
Ma Zhou held onto the rope and looked at Zhang Feng.
He couldn't hold it in any longer. Ever since they had brought the pig over, many students had come over to watch. Now, more and more students had come over. Their gazes were as if they were looking at monkeys.
"Wait here."
Zhang Feng took out a cigarette from his waist and then looked up at the sky.
In fact, he had no idea when this thing would be able to rise.
It was just that there was no ball bag, hanging basket, heating device, or strengthened nylon. Otherwise, it could fly at any time.
The three of them waited in the playground. After about half an hour, the students slowly dispersed.
"Benefactor, I can't hold on any longer."
Ma Zhou's face was constipated. He couldn't hold on any longer. His arms were already sore.
"Wait a little longer. It will be done soon."
Zhang Feng said impatiently.
As soon as his voice fell, a gust of cold wind came.
He was delighted. Once the wind blew, the hot air balloon would float easily.
"Hold up the coarse cloth, quick."
Zhang Feng looked back at the two of them and said in surprise.
"Oh."
Ma Zhou quickly called Hao Chujun. Each of them pulled a corner and held up the coarse cloth.
At this moment, a strong wind blew and directly lifted the coarse cloth. The hot air balloon began to float in the air.
However, the hot air balloon was a little crooked as if it was about to fall down. The pig was also kicking its legs in the air, making the hot air balloon look more unstable.
However, this did not affect Ma Zhou's curiosity. He ran to Zhang Feng's side and exclaimed happily like a child.
"It's flying, benefactor, it's flying."
Zhang Feng took a deep puff of his cigarette and nodded, putting on the look of an elder.
"See, this is a piece of cake. You can make it in the future."
As soon as he finished speaking, the hot air balloon fell to the ground with a bang. Even the pig let out a scream and fainted.
"How did it fall?"
Zhang Feng looked at the fallen hot air balloon and was a little confused. Although he knew it wouldn't fly for long, he didn't expect it to fall so soon. He threw away the cigarette butt in his hand: "Let's go and see what's going on."
After that, Zhang Feng strode toward the hot air balloon. Ma Zhou and Hao Chujun followed closely behind.
The fallen hot air balloon was not far away, about ten meters away. The three of them quickly walked to it.
