"Master, there is a big problem now. We have solved the power, but we can't solve the transmission system." An old craftsman said to Lu Jun with some collapse. The model and reality are still different. When all other problems are solved, the transmission is completely unable to solve it, which can damage the breakthrough of the sky...

The gears in mechanical transmissions are a big problem, the biting performance is a very critical project, and the ball is also a very important thing.

The problem is that the former is barely able to solve it. Well, it is really barely possible. The latter, who can tell me how to make a metal ball of a circle enough, and a large number of metal balls of the same size? This is simply unsolvable. I didn’t consider transmission at all when I was modeled before. As a result, the transmission became an indispensable part.

Lu Jun saw the power simulated by 100 high-quality war horses and wore the non-compliant transmission device in a short time, Lu Jun felt a little broken, but this was nothing, there must be other solutions.

"You make the hull and keel first. I will solve the problem." Lu Jun is basically impossible to turn back at this time, so even if he knows that something is wrong, what he thinks about is not to stop work, but to continue to advance, and he will solve the problem.

"Owner of the family, why don't we try to use impellers as propulsion device?" a master craftsman who knows about machinery hesitated, "In the past, we have designed human-stamped wooden wheel propulsion in the fifth and sixth generations of ships, so it's okay not to drive trains."

"When accelerating, turn in the positive direction, and when decelerating, the ship we designed is too big, and the steam engine you like, you cannot be installed in the original position. Moreover, although the ship has an advantage in speed, it has an obvious disadvantage. The impeller is outside, and our ship will be destroyed after being attacked." The master said with a little headache.

"This is also a solution. As for the problem that the ship is destroyed after being attacked, I would like to ask, can our impeller be installed in the ship?" Lu Jun thought for a while and asked, "How about the sealed cabin designed in a semi-opening?"

"It may cause water in the power system to enter during naval battles." The master said with a headache. "If you don't have a transmission and only use impellers, there is another problem with how to adjust the direction of the rudder, or the power source of the rudder."

Lu Jun looked at the hull deeply, then withdrew his eyes, "Two masters, ten craftsmen who know how to use machinery and seals, follow me to solve this problem. This ship is made, and each master is rewarded with one million yuan!"

By this time, Lu Jun had no choice but to bet on his head and he could not choose to give up his seventh-generation ship. Therefore, even if he encountered any problems, he had to come up with a solution.

Fortunately, the hull structure, due to the great material strength, has been successfully verified that the ship can be made, but other aspects seem to be very problematic.

Therefore, what Lu Jun can do now is to continuously increase the rewards, so that all craftsmen can use their brains to solve this problem with him.

[If this continues, it seems that the problem will not be solved in a short while. There are too few masters here and my level has not reached a high level. If it doesn’t work, it will be mingled with Ma Jun. Zheng Hun’s words are within the system. It is easy to be exposed if you say it. See if you can find Ma Jun.] Lu Jun thought with a confused look on his face, transmission, this is a pit!

On the other side, Zhao Yun, who was far away in Yecheng, was sitting cross-legged on the ground, and the green light sword was placed on his legs. With one breath and one breath, the inner air slowly flowed into the dragon gall spear and the green light sword. An inexplicable slight pulsation appeared in Zhao Yun's heart.

"Finished..." Zhao Yun, who was wrapped in many bandages, suddenly opened his eyes, and his powerful internal energy, with the same pulse as the dragon gall spear, and the blue light sword, poured into his weapons frantically.

At this moment, the blue light sword and the gentian gun were like electric lights when they were incoming calls, and suddenly burst out with a dazzling glow. Then, when the light rose to its limit and was about to jump into another existence, the silver-blue light flashed twice and disappeared completely from the weapon.

"Failed again." Zhao Yun sighed. Zhao Yun's special training ended two days ago. And according to the time when Lu Bu's clone disappeared, Lu Bu's true body should have arrived that day. As a result, Zhao Yun calmly regulated his breathing for a long time that day, and his energy and spirit reached its peak. As a result, it snowed until the evening, Lu Bu did not come.

The next day, even because of Lu Bu's situation in the future, Zhao Yun's mentality fluctuated a little. This situation where he was not up or down, and he didn't know when Lu Bu would come to cause trouble, made Zhao Yun very uneasy.

After all, just thinking about the opponent is Lu Bu, even if it is a top master like Zhao Yun, he feels guilty. Although after a month of special training, Zhao Yun said that even if it is Lu Bu, he has the courage to fight one-on-one, but courage is courage, and whether he can win is the question.

"Brother-in-law, did you succeed?" Ma Chao, who had a faint light on his body, asked at Zhao Yun sitting cross-legged on the ground.

"No, I still failed. At the same time, letting the green sword and the dragon gall spear enter the divine weapon, it is indeed very difficult to condense the spirit." Zhao Yun shook his head and said, "Why haven't Wen Hou come yet?"

"You actually hope that Marquis Wen will come now?" Ma Chao said with a look of surprise, "Are you sure you can beat Marquis Wen? Although you were in the west of the city before, your performance was already amazing and you could face two masters who broke the boundary at the same time, this was not a death battle. When Marquis Wen ascended, he faced six or seven masters."

"Ha, it's nothing. Since you have to do something sooner or later, it's better to come early. It's not a big deal to always be like this, right?" Zhao Yun smiled heartily and slowly released his internal energy. This month was the longest high-level battle he had lasted in so many years.

What Ma Chao thought was just facing Guan Zhang. In fact, when Zhao Yun entered the field, an attack had been locking on Zhao Yun. It was Huang Zhong's arrow. From the beginning, it brought great pressure to Zhao Yun like the sword of Damocles.

It is obvious that Tong Yuan asked Huang Zhong to create a psychological burden on Zhao Yun. The strength of Guan Yu and Zhang Fei is extremely terrifying, especially Guan Yu. If anyone in this era can kill Lu Bu with one knife, it will definitely be Guan Yu.

If Lu Bu had not survived the mental disaster, his divine will had completely transcended the constraints and had no limits, Guan Yu's current level of essence of will would definitely be the most terrifying.

The will of a normal warrior, facing Lu Bu, is just like the will of wood facing metal and iron. Guan Yu's will is almost clear. If Lu Bu's divine will is a divine sword that has been tempered for thousands of times, then Guan Yu's will is at least the level of a steel needle.

Although there is some difference in quantity, in terms of quality, Guan Yu's will is not inferior to Lu Bu. More importantly, Lu Bu's tactic is to cut the opponent to death by flat chopping. Guan Yu's tactic is to break through the limits of humanity in an instant, and the attack intensity is increased to a nonsense level of any defense. No matter if you are in the god mode or the god-demon posture, you will have a knife on the front and cut directly to death.

This is also an important reason why when Lu Bu came to Yecheng, when Guan Yu faced Lu Bu with his sword, Lu Bu would give Guan Yu a face, because Guan Yu was so strong that even Lu Bu could feel danger in Guan Yu.

As for Zhang Fei, the three ways of combining energy and spirit, and powerful attacks, even Zhao Yun’s God mode cannot be resisted. Huang Zhong, the previous one, was beaten to the star.

Including Huang Zhong, who has been attracting no news, if Zhao Yun doesn't show all his strength, he will really kill someone if he accidentally does it.

Especially Tong Yuan could see that his closed disciple was not lacking in strength, but his mentality, so he just told Guan Yu and Zhang Fei to take ruthlessness.

As a result, Zhao Yun, who had basically not been injured on the battlefield in the first 30 years, was carried to Hua Tuo too few times this month.

In addition, Tong Yuan means constant fighting, and it doesn't matter who the opponent is until Zhao Yun is fighting. Therefore, Hua Tuo cannot apply special medicine to Zhao Yun. Most of the time, hemostatic drugs are added with bandages to ensure that the combat power is not lost, and then he throws Zhao Yun back to continue the competition.

After a month of special training, Zhao Yun's strength has made great progress. In Zhao Yun's words, he can beat two or three of him now. Of course, Tong Yuan is just Xiaoxiao, and there are still two or three. Your strength has not changed from a month ago, but you have barely exerted your normal level of strength.

As for whether this level is enough to deal with Lu Bu, Tong Yuan still doesn't have much hope. Even if Tong Yuan is powerful, even if Tong Yuan is a little numb, the blow to break the void makes Tong Yuan a little difficult to face, but Tong Yuan is still very satisfied with his apprentice being beaten by Lu Bu.

"Why, you have to condense two weapons into spirits at the same time? If you are one at a time, you should have succeeded now." Ma Chao held his chin and thought for a long time, and finally confirmed that Zhao Yun was right. If Lu Bu didn't come, it would be okay for them to be worried every day!

"Intuition, my intuition tells me that if I come one by one, no matter which one of them is allowed to have a spirit first, there will be no hope of achieving a spirit in the next one." Zhao Yun shook his head and said, "I don't know what level of Wen Hou is, but I will be stronger if I use a gun and sword relatively, and I will not be able to win if I use any weapon alone."

"You don't think you can win, do you?" Ma Chao looked at Zhao Yun in shock.
