He demonstrated by digging out a small bamboo shoot.

Zhang Yixuan, He Jiong and Huang Lei are in a group, Qin Shu, Peng Yuchang and Zhang Zifeng are in a group.

Peng Yuchang picked up the hoe and dug the mud vigorously, again and again, Qin Shu and Zhang Zifeng watched from the side holding the small hoe.

"Hey..." Peng Yuchang suddenly took two steps back, as if frightened by something.

"What's the matter?" Qin Shu asked, and looked carefully at the ground, but found nothing unusual.

"What a big earthworm." Peng Yuchang pointed to the ground.

"What?" Qin Shu was dumbfounded. There was indeed a long and fat earthworm turning over and swinging in the mud that was dug out. "Are you afraid of earthworms?"

Peng Yuchang laughed in embarrassment. Although it was a bit embarrassing, he was really scared.

Qin Shu smiled badly, bowed and picked up the earthworm with two fingers.

"Brother Qin, what are you doing?" Zhang Zifeng couldn't help taking two steps back.

Qin Shu chuckled and said nothing, and suddenly turned around and sent the earthworm to Peng Yuchang.

"Hey..." Peng Yuchang was taken aback, and quickly took a few steps back, looking cowardly.

Qin Shu laughed out loud, it's so funny, a big man is afraid of earthworms.Frightening Peng Yuchang away, he immediately sent the twisting earthworm to Zhang Zifeng.

"Ah..." Zhang Zifeng screamed and ran away.

Qin Shu laughed again, it was so funny, a single earthworm could scare them and screamed, "Peng Peng, Zi Feng, it said it likes you? It wants to hug you...Look how cute the earthworm is, give it a kiss."

While speaking, he trotted towards the two of them.

"Don't." Peng Yuchang ran away.

"Ah...don't come here." Zhang Zifeng also ran away.

Qin Shu showed a wicked smile, chased after them and continued to frighten them. Peng Yuchang and Zhang Zifeng were chased by him and wandered around in the bamboo forest.

Huang Lei, He Jiong and Zhang Yixuan discovered the situation here and saw Qin Shu chasing the two of them like a bad guy.

"Qin Shu, what are you doing? Don't bully my sister." Huang Lei shouted.

"Brother Qin used earthworms to scare us." Zhang Zifeng complained.

"Earthworm?" The three of Huang Lei were stunned, and then couldn't help laughing. The two were chased by the earthworm, which made people laugh and cry.

Qin Shu stopped, raised the fat earthworm in his hand, and said with a smile, "Mr. Huang, are you afraid of earthworms?"

Huang Lei smiled and said, "It's really big, throw it over here and let me have a look."

"Okay." Qin Shu threw it over, Huang Lei caught it, and suddenly stretched it out in front of Zhang Yixuan.

"Master, what are you doing?" Zhang Yixuan tilted his head slightly and responded calmly.

Huang Lei originally wanted to scare him, but seeing that he was not afraid at all, he smiled and said, "It's okay, I'll let you have a look." Immediately, he suddenly stretched out the earthworm in front of He Jiong.

He Jiong's reaction was similar to Zhang Yixuan's, with a calm smile, "Childish! The two of you are enough." He said Qin Shu and Huang Lei.

Huang Lei chuckled, put the earthworm on the ground, and said, "Keep it, it can be used for fishing in the future."

After the earthworms were released, Peng Yuchang and Zhang Zifeng were relieved and continued digging bamboo shoots.

While digging, the stem and blade of the hoe suddenly separated. Peng Yuchang looked at it blankly for a while, and said, "It's broken, and the quality is too bad."

Take the broken hoe back and put it away, and get a new crowbar to continue digging.

Peng Yuchang dug up the head of the hoe to send some signal, Zhang Yixuan's crowbar was also dug up, the steel was directly cracked, and it was directly scrapped, and it was impossible to repair it.

After a while, Huang Lei's and Qin Shu's crowbars also disconnected back and forth.

Qin Shu joked: "Director, the quality of the tools you bought is too poor. I suspect that the props team got kickbacks."

He Jiong smiled and said: "The things prepared by the prop group are really props, whether they can be seen or not used." He looked at the dug bamboo shoots and said, "Let's stop digging, it should be enough. Pry all dug out."

Everyone is happy, the quality of things is really bad.

Taking the dug bamboo shoots back to the kitchen, they talked and laughed and walked towards the river, where the electric boat was parked.

"This is an electric boat? Isn't it just an extra motor?" Qin Shu complained. A wooden boat was quietly parked by the river. The only difference from the previous boat was that there was a motor installed in the back.

"Come on, go up and try." Huang Lei is a pragmatist, and he will know if it is good or not.

Several people boarded the boat one by one, Huang Lei sat at the stern to drive, turned on the switch to power on, twisted the 'throttle', the electric motor whined, driving the propeller to rotate at a very high speed, and the water flow rolled.

As the boat slid forward, Huang Lei stepped up the throttle, and the speed became faster and faster, creating wide water marks in the water.

"This thing is really useful."

Qin Shu, who was complaining just now, did not escape the "True Fragrance" theorem. Compared with the previous boats with motors, no matter in terms of speed, strength, maneuverability or work efficiency, they are not the same, and there is a qualitative leap. .

Crossing the river is no longer a problem.

The clear river water reflected the green trees on both sides, and Huang Lei steered the boat upstream. At this moment, they were not working, but playing.

He Jiong sounded the advertisement of the gold master's father, and said: "Peng Peng, I have a question for you.... A river, the two opposite banks are 350 meters apart. It takes 11 minutes for a boat to go down the river to the opposite bank, and it takes 16 minutes to go upstream. What is the velocity of the water in this river in [-] minutes."

Peng Yuchang cooperated with He Jiong in advertising. He thought about it for a while, but didn't say anything right away.

Qin Shu interrupted and teased: "Mr. He, there is something wrong with your question."

"what is the problem?"

"The width of the river is known, and the speed of the water flow is not rigorous. The water flow flows up and down, not left and right. The time for the boat to go to the other side of the river is not affected by the water flow. No matter how much the water flow is, the time for the two sides of the river to go back and forth is the same. Same.

Also, you didn't say that the speed of the boat is constant, it can be fast and slow for a while, and the speed of the water flow is the same.Two unknown variables, impossible to figure out. "

"Ah?" Peng Yuchang and Zhang Zifeng were dumbfounded, they didn't understand what he said.

Huang Lei understood, and said with a smile: "Qin Shu is right, the question is not rigorous, and the time for the boat to go back and forth between the two banks is not affected by the current."

He Jiong thought for a while, but he couldn't figure it out. He just read it. Since there is a problem, he can broadcast it so as not to mislead the students. He smiled and said, "Qin Shu, how do you change it? Just cut it out."

Qin Shu thought for a while and said: "On a river with a uniform flow of water, there are two points ab. The two points are located upstream and downstream, with a distance of 352 meters. It takes 11 minutes to travel upstream from point b to point a, what is the speed of the river?"

"Yo ho, amazing!" Zhang Yixuan joked, although he didn't know right or wrong, but compared with what He Jiong said before, there were more words and more clarity.

Qin Shu said modestly: "What's so great, it's just an elementary school problem." This time he told the truth without showing off.

Peng Yuchang joked with a smile: "Primary school questions? Do you mean that we are not even as good as primary school students?"
