After ending the conversation with the architect, according to Xu Yiyi's instructions, Dai Huadong found the place where Xu Yiyi and the others were, and after shopping for about an hour, Dai Huadong resolutely abandoned Zimu and left him alone to accompany these girls who were full of energy as soon as they went shopping.

[Hmm...... I'm kind of craving to buy something. The outlying islands, which have been watching from the sidelines, said in the deep-sea network.

[Woo...... I just wanted to buy some essentials to go back to...... But it's not good to refuse it directly......] Xu Yiyi said.

Dai Huadong, who had been relieved, rolled his eyes: [Anyway, I have already run away. Speaking of outlying islands, you actually like to go shopping? Do you still need to buy things in the deep sea? 】

[Your human books are still quite useful, I used to read human strategies to make up for my shortcomings. 】

【…… I'm curious how your world hasn't been dominated by your deep sea. Dai Huadong complained, [Hmm, I seem to have seen Wang Dong. 】

【Wang Dong...... Who's here? The outlying island said that he had forgotten about this person.

[It's our classmates...... Aren't we still in the same class of martial arts? Xu Yiyi said.

[I haven't seen it for a long time, I forgot, it's not an important person anyway.] 】

【…… People are also a protagonist, right? Dai Huadong complained.

"Hey! Wang Dong? What are you doing here? Dai Huadong greeted them.

"Second brother?" Huo Yuhao, who was with Wang Dong, saw Dai Huadong.

"I said why didn't I find you before, so you were wandering outside. It's been a long time, and that schoolgirl named Xuedi misses you very much. Wang Dong looked at Dai Huadong and smiled.

"Eighty percent because I have toffee and chocolate that aren't available in the store." Dai Huadong spread out his hands, and then looked at Wang Dong carefully, "It's that you have long hair and look more like a girl." Either I'll give you an operation and turn you into a girl, and then you can marry Huo Yuhao. ”

Wang Dong's face turned red at a speed visible to the naked eye, but he didn't shout like before, but pretended not to care and said, "Come on, I don't want to change gender." And how can a man become a girl? ”

"That's it, second brother, don't be kidding." Huo Yuhao said.

Dai Huadong showed a sly smile: "I still know a lot about the structure of living organisms, and it is not impossible to turn a man into a girl." Why don't I do an operation on Yu Hao and marry you after turning him into a girl? ”

"Absolutely not!" Wang Dong said loudly, startling Dai Huadong next to him, and the passers-by around looked at Wang Dong who made a movement.

"Why are you so excited? Scared me. Huo Yuhao said, "And if you keep quiet, everyone else is looking at you." ”

"Uh......" Wang Dong saw the strange gaze cast by the people around him, covered his face and ran away.

Huo Yuhao shrugged helplessly and followed him. Dai Huadong followed unhurriedly.

The three of them came to a park, where Wang Dong stopped.

"Hmm, I was just kidding, how could I have that kind of surgery, but it seems that our proposal to change Yuhao into a girl has a lot of opinions." Dai Huadong looked at Huo Yuhao with a smile.

"Second brother...... You're not kidding. Huo Yuhao said helplessly, "By the way, I heard Wang Dong say that the soul guide department seems to have encountered a problem on a project proposed by you, second brother." ”

"Huh? What is it? Dai Huadong asked.

"Dean Qian Duoduo of your soul guidance department said that it seems to be a rocket? When he knew that I was coming to Mingdu, he called me to come over. Wang Dong said.

"What's the problem?" Dai Huadong was stunned for a moment.

"Dean Qian Duoduo's original words are like this: Wang Dong, you have a good relationship with Yu Hao, you should know his second brother Dai Huadong, right? When you go to see Yu Hao, by the way, you can help me give Dai Huadong a message, just say that there is a problem with our rocket research, and the range and speed can no longer be improved, and ask him what he can do. Wang Dong's imitation is vivid.

However, Dai Huadong didn't laugh, he frowned and said, "What's the specific situation?" ”

"It seems to say that because the speed is too fast, the outer layer will explode in mid-air due to the high temperature melted due to air friction, and then it can't last too long if you use the soul guide shield, and the speed is reduced after using the soul guide shield, but the metal that can withstand that high temperature is quite expensive, and Shrek doesn't have much, so it's not realistic to apply, so I hope you can find a way to solve this problem. That's what he said. Wang Dong said, "Anyway, I don't know much about this, so it's better to cultivate hard if you have the heart to do this." ”

"You can't understand the fascination of science with only muscles in your head." "Because of the high temperature of friction, the shell melts...... Speaking of which, I don't think I forgot to tell them about thermal coatings. ”

“？？？” Wang Dong and Huo Yuhao don't know why.

"Speaking of thermal coatings...... I don't know how to get it. When you go back, tell Dean Qian Duoduo and say that I will study this kind of thing, and let those chemistry students try to make a good quality thermal insulation coating that is easy to mass-produce and can be. Dai Huadong said, "By the way, how is the research progress of other projects?" ”

"How do I know that?" Wang Dong rolled his eyes, "I'm from the Martial Soul Department, and those are the secrets of your Soul Guide Department." Coupled with the fact that those exchange students from the Sun Moon Royal Soul Master Academy came to Shrek, we are even less clear. ”

"Well, I shouldn't have counted on you, we'll be back in a few months, and we'll be able to understand the situation then." Dai Huadong waved his hand.

"Okay." Wang Dong said, "Speaking of the drawings sent by Yu Hao to Tangmen, the first batch of finished products has been highly praised, especially the Zhuge God ballista, and the academy has specially placed a batch of orders. Although the rifle you made is not bad, the power is not at the same level as the Zhuge God Ballista. He said with a proud expression.

Dai Huadong thought about it, and felt that it was better to ignore him, this product would be a thug in the Tang Sect, his IQ was too low, and he had the ability to enlarge this thing in equal proportions to the same caliber to see who was more powerful.

But Huo Yuhao said: "This thing is not so compared, Wang Dong, I have also seen the kind of weapon of the second brother, even ordinary people can make and use it." And my Zhuge God Ballista can only be made by a soul master, and the cost is quite expensive, although it is powerful, but the cost performance is not as good as the second brother's rifle. And if you want to say that the design is smart...... It's still the second brother's cleverness. Huo Yuhao remembered the weird weapon that Dai Huadong had used before to create terrifying high temperatures, and it seemed that he didn't need soul power......
