"Yo! Why did it take so long to come out? What's going on? You can't be scared stupid by those vicious guards, right? As soon as he came out of the arena, he was greeted by a young man with flaxen, fluffy hair.

"You are?" Lin Feng asked.

"Oh, I'm the one who just drove Peace." The young man laughed. "Sure enough, it's you, a powerful boy who defeated the attack with a pile of broken copper and iron!"

"You know me?"

"Well, I was there for that game of yours." The young man replied, reaching out and patting Lin Feng on the shoulder again. "Young people, it's a good thing to know the times, it's the right choice to give up the challenge, you have to keep working hard!"

"Well, I challenged it, and it seems like I succeeded......"

"It's normal for a challenge to succeed, and it's important to recognize that there are gaps...... Wait, it worked? The young man was stunned.

"It's identification." Lin Feng took out the foreign guard's identification certificate with his name printed on it and put it in front of the young man.

"How is that possible! Were you too lucky to pick the weakest? No, you shouldn't be able to win even the weakest...... Who did you challenge? The young man scratched his hair in a tangled way.

"Tampa." Lin Feng was very happy when he looked at the young man's incredible appearance. "The outer guard is number one, driving Ivan's one."

"Tampa! Are you kidding me? You beat Tampa? The young man froze in shock.

"Hey, are you alright?" Lin Feng was stunned when he saw the young man, and patted him on the shoulder with concern.

"Don't touch me!" The young man suddenly jumped in place, turned around and left, and whispered to himself as he went: "I must have been dreaming if I succeeded in the challenge and defeated Tampa...... I must be dreaming......"

Lin Feng watched him walk away in a daze, shook his head and sighed, and walked towards the residence in the opposite direction. "What a young man, he went crazy......"

After Bai learned that Lin Feng had successfully advanced to the outer guard in the challenge, he gave Lin Feng another list of materials.

"This is the list of materials for the second-order gene enhancer, and it must be collected before the Hongwu Dojo comes to the Wang family to assess the enrollment." Bai commanded. "Advancing to the second level of physical fitness score can increase your likelihood of passing the Hongwu Dojo assessment by 24.32%."

Lin Feng was in trouble. Now with Lin Feng's strength, he can already hunt in the wild D-class dangerous area, but at least half of the materials in this list are not produced near South Wind City. And to buy these materials, it costs at least the money to buy two green wolves!

Lin Feng was promoted very quickly along the way, but there was no accumulation at all, and his wealth was only enough to maintain a slight surplus in his daily expenses. And even if he didn't eat or drink, Lin Feng would need at least two years to accumulate all the second-order gene enhancer materials.

What to do? Lin Feng began to struggle.

The next day, after Lin Feng finished his training at the God of Machine Warfare, he walked around the Internet, intending to relax.

"Huh? Navy Club? Lin Feng moved to a secluded corner of the community, in front of a building like a bar. Let's go in and have a look......"

"Therefore, there is no way for biocalcareous materials to polymerize and deteriorate! Your conjecture is absolutely wrong! ”

"I've thought about what you said for a long time, but have you ever thought that in the state of absolute zero, all the molecules and atoms that make up matter stop moving, and you can completely control the potential energy of manipulating calcium atoms!"

"This situation simply doesn't exist, and even if you can achieve an experimental environment of absolute zero, how do you operate it? What tools to use? You're a fantasy! ”

"It's just conjecture! We are arguing for the possibility of a conclusion, not the feasibility! ”

"Fart! How can a conjecture without feasibility come to a conclusion that is truly realistic! ”

……

As soon as he stepped into the gate of this building, five old men who were blowing their beards and glaring at him appeared in front of Lin Feng. After Lin Feng appeared, the five old men just glanced at him, ignored him, and continued to devote themselves to the state of war.

Lin Feng was not angry, he felt that such an environment was quite comfortable. He casually found a seat and sat down, watching the five old men quarrel with great interest.

At first, Lin Feng just watched the excitement, but when he listened to it, he was interested. The problem they discussed was actually the content of mecha engineering! Although there was a lot of content that he couldn't understand, the knowledge contained in it made Lin Feng very interested.

So Lin Feng developed such a habit, every day after training in the God of Machine War game, he would come to this small club to listen to the five old men discuss or quarrel. The five old men also noticed that this patient young man, when he encountered some basic problems and technical terms in discussions or quarrels, he would say two more words of explanation and explanation, which made Lin Fengmao pause.

On this day, one of the old men named Aldo pulled out a mecha engine blueprint.

"See what I've gotten on? Stark's original manuscript from that year! Zero-heat engine! He shook the blueprint in his hand triumphantly and showed it off to the other four old men.

"Zero-heat engines have proven impossible, and Stark's design is just a possibility, and it can't be built at all!" One of the old men raised his beard and said mercilessly.

"The hotter the engine, the higher the energy loss rate, but the real 100% energy utilization rate is simply not possible. Even Stark's design only makes the energy loss rate infinitely close to zero. An old man suddenly explained. Lin Feng knew that this was these old men guiding himself, so he hurriedly wrote it down by heart.

"Well, I agree. But how about we perfect him? He shook the blueprint again and showed off to the old men. Discuss some things all day long, why don't you take something practical and do it! ”

"That's a great idea to pass the time!" The four old men's eyes lit up and nodded in agreement.

Then, the five old men threw themselves on this design drawing, studying, discussing, and arguing, and Lin Feng sat and watched, listening, and learning. Four or five days passed like a white horse.

"We can add an additional partition to divide the warehouse into two, one primary and one secondary. The medium inlet of the evaporator is connected to the secondary bin of the impeller silo, and the outlet of the primary silo is connected to the import of the secondary silo. Add a conversion step to make the most of the heat dissipated. ”

"No, the diameter of the impeller shaft will be greater than the inner diameter of the inner cavity of the warehouse, and one side of the impeller shaft and the side of the inner cavity of the warehouse will produce empty heat storage!"

"How about the blades pass through the blade perforation in the impeller shaft and are in close contact with the chamber cavity? Form an isolation place, and the conductivity will go up a notch! ”

"But the friction on the blades is too great! The service life will be shortened to an unacceptable extent! A day or two to change an engine, who can stand it? ”

……

The five old men threw themselves on this design drawing, not thinking about tea and food, scratching their ears and cheeks all day long, but the plans were put forward one by one, and one by one they were rejected, and after four or five days, none of them were feasible.

Lin Feng looked at it for four or five days in a row, and felt that this design was becoming clearer and clearer in his mind. There seemed to be a flash of inspiration, but I couldn't catch it. He looked at the five old men who were still discussing the research in full swing, and involuntarily stood up: "Or, let me try?" ”
