Having said that, Tong Yuan is actually very clear that someone in the Central Plains can solve this problem, and even the other party's technical level is enough to push the range of this secret technique to fifty kilometers in one breath, but Tong Yuan really doesn't want to deal with the other party.

Because the other party is called Nandou, an immortal who is a psychopath in Tong Yuan's concept. When facing creatures like immortals, Tong Yuan has never been able to regard them as human beings. Including Nanhua, Zuo Ci, Zixu, etc., Tong Yuan doesn't want to deal with them.

[You have to think of a solution, otherwise, you really can't explain it to him.] Tong Yuan was inexplicably sighed, [This type of secret technique can be solved by finding an immortal. Even if you don't have the level of Nandou, it can be expanded by more than ten times. I really don't want to find it!]

Tong Yuan and the immortals have fought many times, so he knows very well what the immortals can do, what light they can disperse, what they can become qi, and what long-distance communications can be.

"Brother Tong, Brother Tong..." The second uncle of the Zhang family greeted him twice before Tong Yuan reacted and coughed twice with a little embarrassment. "I just remembered some things, so you can continue talking."

"If this doesn't work, it's always possible to convert the essence of heaven and earth into motivation." The second uncle of the Zhang family didn't care too much about Tong Yuan's distractedness, but naturally changed the topic.

"Don't you have a heaven and earth essence engine? The powerful power is shocked to me." Tong Yuan asked in confusion. Tong Yuan had also felt the heaven and earth essence energy-steam hybrid system, which was very powerful.

"Only that one is far from enough." The second uncle of the Zhang family sighed, "That thing is not easy to make, it is basically something that can be used for one thing."

"Is this true?" Tong Yuan was really not very clear about this, "But the transformation of the essence of heaven and earth into power also requires a support, and it is impossible to directly convert it!"

"Well, I think about it." The second uncle of the Zhang family frowned. Since he could not achieve what he wanted, it was important to choose an adaptable thing.

"Second Grandpa, the test site is ready. Can't you go?" Just as the second grandfather of the Zhang family was thinking, the junior of the old Zhang family greeted outside.

"Brother Tong, I will think about it first, and then go back to design a transformation device and then consider how to convert power. Let's go to the test site first. Haven't you always wanted to feel the power of the naval gun?" The second uncle of Zhang family said with a smile, "Although this thing is not a single weapon, you can also feel it."

Tong Yuan has always been very interested in the power of naval guns. In addition, the Zhang family has always said that this power is particularly powerful, and Tong Yuan inexplicably wants to experience it himself.

"Can the naval gun be tested?" Tong Yuan touched his beard, "Then let's take a look and see what the so-called unparalleled power is."

"Dangdangdangdang!" Yang Jian beat the gong in Yecheng Prison, making Lu Jun and the other two quarrel, so that the three guys had already taken out their things and threw them towards Yang Jian from the gap in the prison's wooden pillars.

"Yang Mingtong, if you do this, we don't even have to do friends when I go out." Lu Jun was the most irritable. He grabbed the wooden pillar in the prison with one hand, reached out with the other, holding the screwdriver, and seemed to want to teach Yang Zhu a lesson.

"Lu Jicai, if you do this, I won't let you let the news today." Yang Fei said dissatisfiedly. Although he didn't want to mess with these three bastards, if he underestimated him, Yang Fei felt that it was necessary to teach these three guys a lesson.

"When we were studying early in the morning, you came to beat the gong. Do you need to beat the gong when you let the air?" Lu Jun's head was almost squeezed out of the wooden pillar in the prison, pointing at Yang Wei and shouting angrily, "What's more, do you think the three of us need to let the air when we let the air?"

"Okay, Lu Jicai, you are really good." Yang Jian ran over quickly, and knocked Lu Jun, who was squeezing between the wooden pillars of the prison with a gong, which made the other party's eyes shook.

"Yang Mingtong, you wait!" Lu Jun angrily scolded Yang Feng.

"I'm afraid of you?" Yang Jian was not a fuel-saving lamp. "I'm here to inform you to let you go and see the seventh-generation ship and cannon evaluation. You've treated me like this. Well, wait. Even if you escape from prison today, I'll catch you back."

Yang Fan said while running out. Lu Jun and the other two were stunned when they heard this, and immediately roared and asked Yang Fan not to run away.

"Let me go out. It was the seventh generation ship and naval gun structure design I carried out. I want to participate in the evaluation!" Ma Jun stretched out his hand from the pillar of the black prison and roared angrily.

"This is a plan I proposed. I have also promoted the seventh generation ship. The naval gun evaluation cannot be without me!" Lu Jun also shouted, completely forgot that there was something else.

While Ma Jun and Lu Jun were roaring, the sound of sawing wood was already heard on the wooden pillars of the black prison on the other side. Lu Jun and Ma Jun turned their heads at the same time and found that Zheng Hun had his legs pressed against the wooden pillars of the black prison. He was holding a wire saw in his hand and was driven by mechanical hybrid power, and was sawing the wooden pillars of the prison at an extremely high speed.

It was estimated that with the power of this thing, at most, the wooden pillar would be sawed off by Zheng Hun. Ma Jun and Lu Jun immediately lowered their heads and untied the string as decorations on their shoes, and then pulled out their props.

Ma Jun quickly took apart the rope as decoration, pulled out the chain with irregular blades inside, then took the previous materials on the spot, quickly assembled it into a chain saw, then quickly turned the mechanical wind to accumulate mechanical energy, and then pulled it suddenly, with a buzzing sound, Ma Jun held the chain saw and started to saw the wooden pillars of the prison directly.

This is a high-speed chain saw combining the operating principles of the mechanical clock, the principle of naval gun potential energy conversion, and the original production of the Tiandi Jingqi-Vapor hybrid engine.

On the other hand, Lu Jun used the same technique to quickly combine a rope saw and whimpered at the prison wooden pillar in front of him. For the three mechanics masters who learn from each other's strengths and weaknesses, the prison wooden pillar was nothing. If they hadn't been to hide in the black prison, they wouldn't have been locked up here.

The three of them quickly dealt with the prison wooden pillar in front of them. After ten breaths, Ma Jun, who had the most noise, had directly sawed off a whole wooden pillar with a chain saw. Then Zheng Tai and Lu Jun also destroyed the prison door in front of them almost at the same time.

Then the three of them rushed out of the prison door with their own weapons in one hand. The prison escape was a ghost, wasn’t it just an increase in the punishment time? The three of them still cared about this, because they were in a black prison because no one disturbed them when they studied here.

However, when the three of them rushed out of the prison with their own tools, they were facing them. More than 300 soldiers around the sheep were guarding a semicircle and observing the three of them with large shields. Lu Jun and the other three were extremely embarrassed.

"Yang Mingtong, what do you want to do?" Lu Jun saw this posture and knew that it would be impossible if he wanted to run today. However, now the naval gun needs to be evaluated. If the three of them do not participate, then they are still humans? Therefore, no matter what, this level needs to be passed.

"It's less than thirty breaths." Yang Wei said as he looked at Lu Jun.

"What did you say that you are less than thirty breaths?" Lu Jun didn't understand what Yang Zi was talking about.

"You three, from the time I walked out of the prison to the time you three demolished the prison and rushed out, it took less than thirty breaths. Let me take a look, chain saw, wire saw, rope saw, it should be said that the prison itself cannot hold you back, right?" Yang Wei stared at Lu Jun and asked.

"Cough cough!" Lu Jun coughed. Although they were willing to stay in prison and find such a quiet place to study, they also had the ability to leave at any time.

"Since this prison cannot hold you, and there are so many witnesses, I plan to send you to another place for imprisonment. I have applied for you. Come and sign each person." Yang Jian took out three pieces of paper from his sleeve and shook it at the three of them. He didn't want any of these three guys to stay with him at all.

"Sign it." Zheng Hun glanced at the content and knew what Yangzi meant, but the time was too good now, and they were unreasonable, Yangzi also gave him a step forward.

Lu Jun looked at the content in anger, and directly touched some ink and pressed a mark, "It's OK now, let the three of us leave."

"These people are here to pick you up." Yang Wei put away the documents with satisfaction, then pointed to the soldiers beside him and said, "Don't come back if you go."

After saying that, Yang Fei left without looking back. Recently, many people came to him to inquire about Lu Jun. Although he could not go to prison because of the rule, he was also very annoyed by Yang Fei. Now that he solved the problem in one breath, it is also a good thing for Yang Fei.

As for repentance, sheep is not afraid at all. As long as you sign something, sheep has the means to drive these three guys away. No matter how bad it is, it has the power to make them out of a place they think no one will disturb, and that is enough.

"Three, please come with me. The place where the naval gun experiment is still very far away from here. Please go to the inn to transfer to the carriage first." After Yangzi left, the leading captain saluted Lu Jun and the other two, and then made an invitation.

Lu Jun and the other two knew that they had been fooled by the sheep, but now that things have come to this point, it is hard to say anything, not to mention that the major events such as naval gun experiments do have extraordinary significance for the three of them, so the three of them no longer say anything and follow the other party quickly forward.

At this time, the younger generation of the Zhang family was gradually assembling the naval guns of the seventh-generation ships based on various equipment.
