After listening to Yuan Fang's words, Yang Xing didn't want to leave, he stayed here to learn to drive an airship, but the imperial capital still had a lot of things waiting for him to deal with, and he couldn't go back if he didn't go back.

This is the same as driving, no matter how rich you are, when you just have a car, you are eager to experience the thrill of driving in person, and now those luxury cars have a full-time driver and a big boss who sits in the back seat, and it is estimated that there are few who can't drive.

Yang Xing and the others left, and the others who should have left were also withdrawn, and the base returned to its former tranquility, only the workshop was still full of enthusiasm.

In the cave halfway up the mountainside, the guards at the entrance of the South Gate Yang saw that the guards at the entrance of the cave left, and pulled the boss Nanmen Tie to the entrance of the cave: "Big brother, what do you say they are going to do?" If you don't let it out, it doesn't matter, and the hole is sealed at every turn, and you can't even breathe, by the way, and what was the movement just now, as if something exploded. ”

Nanmen Tie said casually: "Don't think about it, remember, let's just do our own work, don't ask or guess the rest." Nanmen Yang looked at the eldest brother thoughtfully, nodded and said no more, the two came to the entrance of the cave, took a deep breath greedily, and let the cold air pour into the lungs, that feeling was very comfortable.

On the way up the mountain, Yuan Fang saw the two brothers Nanmen Tie and Nanmen Yang at the entrance of the cave at a glance, and he smiled and waved to greet him: "Are the brothers busy?" ”

Nanmen Tie said with a smile: "Ah, I just finished burning a furnace and came out to breathe." ”

Seeing such a large number of people going up the mountain, Nanmen Yang couldn't help but ask curiously: "Lord Yuan, you are." ”

Without waiting for Nanmen Yang to finish speaking, Nanmen Tie coughed lightly to remind his extremely curious younger brother, and then smiled and said, "Lord Yuan, have you eaten?" ”

Yuan Fang was speechless for a while, asked Lin Mengsheng and them to go back first, and went to chat with the two brothers of the Nanmen family for a while, asked about the production progress of the gas stone, and looked at it casually, skillfully avoiding the exploration of the iron words of the South Gate, and only left with Sang Rou and them at dinner time, and went up the mountain to return to the base.

Today's test was very successful, according to the usual practice, the chef prepared a sumptuous banquet, as the chief creative and technical director of the base, Yuan Fang naturally became the target of public criticism, not long after the banquet was surrounded by a large number of wine glasses, Lin Mengsheng, the black boy who faintly became the director of the base, was not much better, after a while, the two of them were roasted with fire-like enthusiasm on the outside and tender on the inside, and they were put down and carried back to the room before they could eat. Lin Mengsheng was really happy, and when he was sent back, he was still yelling to continue drinking, saying that this was the first time in his life that he had drunk and was happy.

Yuan Fang was different, although he also shook his tongue and didn't obey the call, but, when he returned to his room, he sat on the sofa as soon as the door was closed, sighed and said, "I'll take it, this won't let people eat well, Jingqiu, have you eaten enough?" ”

Ouyang Xianxue's eyes widened, and she said in surprise, "Brother-in-law, you haven't drunk too much?" ”

Yuan Fang said smugly: "This little wine wants to put me down, it's still far away." ”

Ye Qingru looked at Yuan Fang in surprise: "Brother-in-law, this is not like your character, aren't you addicted to alcohol?" Why did you hold back this time? ”

Yuan Fang said depressedly: "I want to have a good drink, there are still a lot of things at hand, who will do it if I drink too much?" Sang Rou, you don't have to accompany me, you didn't eat much just now, let's go back, I'm still waiting for you to bring me something to eat, by the way, it's better to get more elbows back, as well as pig's trotters, and the pig's ears that were mixed. Sang Rou didn't want to leave, but when she heard Yuan Fang say this, she couldn't help but laugh, discussed it with Yu Jingqiu and them, leaving Yu Jingqiu and Huo Bingyan to take care of Yuan Fang, and the remaining six people set off with high morale and went straight to the banquet, and a big sweep was about to begin.

Yuan Fang sat at the desk and pondered, in the sofa not far away, Yu Jingqiu and Huo Bingyan whispered about the experience of driving a fog balloon, and after a while, Yuan Fang sighed, picked up the tea and took a sip.

Yu Jingqiu looked back at Yuan Fang: "Brother-in-law, did we quarrel with you?" ”

Yuan Fang shook his head: "No, it's just that my brain is a little messy." ”

Yu Jingqiu and Huo Bingyan got up and walked to Yuan Fang's desk, each moved a chair and sat down, Huo Bingyan asked curiously, "Brother-in-law, do you have any plans?" ”

Yuan Fang nodded: "The speed of the fog balloon is still too slow, I plan to improve it." ”

Yu Jingqiu asked with great interest: "Do you have a clue?" ”

Yuan Fang said distressedly: "No, I don't have a clue at all. ”

Huo Bingyan thought for a moment and said, "Actually, I think the fog balloon is already very fast, although it is not as fast as an airship, but it is much faster than running on the ground on horseback." Brother-in-law, if you don't want to use fog balloons, just use airships. ”

Yuan Fang shook his head: "The speed of the airship is fast, but there are also many drawbacks, that thing is large and inflexible, and it consumes too many fog stones, let's just point to the bottom of the family, what fog balloons or airships are used up by fog stones, all of them have to become waste." ”

Yuan Fang took precautions and made careful calculations, but Huo Bingyan didn't care and said: "Don't lie to me, didn't the fog stone mine send news a few days ago, the reserves of fog stones are very large, I calculated, according to the consumption of two hundred airships and two hundred fog balloons, even if it is a non-stop flight day and night, it is enough for us to use it for ten or eight years, this is still a conservative estimate." ”

Yuan Fang spread his hands and said: "No matter how much, this kind of non-renewable energy will always run out one day, we can't patronize ourselves, and we have to leave something good for future generations." ”

Yu Jingqiu suddenly said: "Brother-in-law, do you plan to develop new power energy?" ”

Yuan Fang did not deny it, nodded and said, "I have this idea, but I don't have a clue at all." ”

Yu Jingqiu reminded: "Didn't you say to use heat at the beginning? I think the air stone should be fine. ”

Yuan Fang said with a bitter face: "The gas stone is a good thing, but that thing is a bit dangerous, if you don't get it right, it will explode, and the result will be that the machine will be destroyed and people will die, and then there is, although the heat also has a certain amount of buoyancy, but the effect is far inferior to the fog, alas, forget it, I don't want to think about it, let's solve the current problem first and get through the difficulties." Bing Yan just reminded me that we can make a batch of miniature airships, and if they are also suitable for fog stones, their own weight is light, and their speed should be increased a lot. ”

Yu Jingqiu wondered and asked, "Brother-in-law, why do you keep insisting on fog balloons or miniature airships with strong maneuverability?" If you want me to say, if you have the materials to make those things, you might as well make a few more airships. Huo Bingyan nodded in agreement, looking at Yuan Fang with the same confusion, they really couldn't understand why they had to make a miniature airship in such a good move.
