It is precisely because of Zhang Tianyou's instructions that there were no outsiders to disturb during the renovation and decoration of the martial arts hall, even if it was a fully enclosed operation during the renovation, no one cared about it, which is why Zhang Tianyou issued a guarantee.

"It's still Lao Zhang's family's problem for a long time, you have to introduce it later, we have to have a good relationship with your nephew's family!"

The adult laughed, and asked Li Qing to come over to greet the adult, and it was an honor for the adult to come. Zhang Tianyou, who didn't know why, said hurriedly.

"Hehe, Zhang Zhutou, don't you want to make trouble for your family, don't you understand when you look at the height of the flying fortress?" Huang Dali reminded.

"Is there anything wrong with the height? Zhang Tianyou didn't react.

"The air defense system of the old metropolis did not respond. Deputy Chen Dayong reminded.

"Lao Zhang, you! How shrewd people are on weekdays, why are you confused when it comes to your own family, you and I don't know about the flying fortress, but it is already below a thousand meters altitude, and the air defense system doesn't even have an early warning?"

"What adults mean that it didn't pass through our direct authorization by Skynet to go up and down freely without security checks, right? But how is this possible, I knew Li Qing when I was very young, almost I watched her grow up, her work and marriage were all facilitated by me, how could I recognize the big people at that level. Zhang Tianyou retorted incredulously.

"Isn't this obvious? What's the fuss, it's just that the difference between before and after is too big for you to accept it for a while, and it's a good thing for you to calm down!"

"Congratulations and congratulations! In the future, this SY county will be taken care of. Huang Hai said politely.

"Let's wait for Li Qing to come out, I'll ask you later, because I've treated him a lot over the years, and he's really hidden deep enough. Zhang Tianyou said angrily.

Everyone on the side smiled, and they all understood that Zhang Tianyou was just angry with his relatives for concealment. But the worry in my heart can't be hidden.

The speed of the flying fortress descending more and more slowly, everyone below had a feeling of being overwhelmed by a mountain, and the dark metal shell made the castle-shaped fortress add a solemn aura.

"Although it is not the first time I have seen the Flying Fortress, I still feel so apprehensive about goodbye, and the deterrent power created by that kind of technology is still so palpitating. Huang Dali said with emotion.

"What the Ancestor said is! From my own point of view, this kind of self-customized flying fortress can't be built without a billion yuan! In addition, this launch base doesn't cost billions of gold coins, don't even think about it. I didn't expect that there was an invisible giant in our SY County. Li Xianling said in amazement.

"How can adults be so expensive, can't they be bought in tens of millions of dollars?" Chen Dayong asked in disbelief, and Zhang Tianyou on the side also looked listening and waiting for Li County's answer.

"Haha! The kind of flying fortress you are talking about is just an ordinary transport type flying machine, do you know what a fortress is? It is a combat unit, it is almost impossible to conquer it in this flying fortress soul refining realm, as for the supernatural power period, you have to ask Huang Lao Zu. Li Xianling said happily, he was very happy in his heart, and now with the existence of this flying fortress, the security level of SY County has been directly increased by more than two stars.

In this way, no matter what crisis arises in Datang, SY County will have an air strike force. Moreover, it is also a heavy firepower strike force of super three products and one star, and the top-level weapons of the second grade of air technology are equivalent to the deterrence of the middle and late stages of supernatural powers. Li Xianling, who was born in a wealthy family, was reluctant to tell the truth, just to take care of Huang Laozu's face.

"Haha! The county order is to take care of the face of this seat, just now I checked it with my divine sense, and it is indeed as Li County Commander said, the second-grade top-level air armament, and the military industry under the Datang Academy of Sciences is produced. A few supernatural powers can't take it in the early and middle stages, and it will only pose a threat to it in the later stage, and there is little chance of keeping it. I'm not afraid of everyone's jokes, and I've always wanted to have such a flying fortress as my own air palace. Huang Dali said directly and heartily.

"In front of this big guy, the siege tactics below the supernatural power period are basically blind, and if there is enough ammunition, the county town of SY will be completely at ease. Li County Ling then added.

"Hehe! There is plenty of ammunition to cover the attack, which can last for up to two months without interruption, and there will be ammunition that has been ordered for a year. Welcome to the Jingwu Fighting Gym, please wait a while for the Flying Fortress to complete the landing before inviting everyone to visit. Yu Zhifang walked out of the main gate and said politely to everyone.

"Brother Yu doesn't know where my nephew is now, I have something I want to ask if I can let him out. Zhang Tianyou stepped forward and asked, because he was entertained by Yu Zhifang when he didn't visit here a year ago, so he was no stranger to him and asked directly.

"Hehe! The hall owner will also complete the handover of the flying fortress, and Mr. Zhang can ask someone if he has any questions, and the hall owner has explained, and he will not hide it from you too much. Yu Zhifang replied with a smile.

"Can you tell us more about the situation of this flying fortress? And where did Li Qing get the gold coins to buy such a valuable battle weapon? He didn't do anything stupid!" Zhang Tianyou asked with concern.

Li Xianling and Huang Dali behind Zhang Tianyou, as well as his subordinates, were silent on the side, and they were also curiously waiting for Yu Zhifang's answer.

"The owner of the museum is very good now, and he has not done anything stupid, as for this flying fortress, it was specially ordered last year for the owner's family to have a safe living environment, and now it has finally been delivered. As for the source of the owner's gold coins, it is better for Mr. Zhang to ask in person. Yu Zhifang explained.

Everyone knew that the two questions they were concerned about were shirked by the other party, and it was normal to think about the scene, except for the fact that more and more nearby residents gathered behind them to come and watch, how could they be so mindless to answer private questions.

At the foundation of the Jingwu Fighting Gym, Qianlong and his father Li Qing's subordinates, Tiansheng, as well as the old pig and the big head, are all waiting for the lower and lower Flying Fortress to seamlessly connect and set the foundation.

"This gold coin is not spent in vain, every penny is worth the price! Mighty and domineering! Dad, with this guy guarding you, I will feel a lot more at ease when I go out." Qianlong exclaimed happily.

"You kid is too loser, such a big guy is not customized, now those students who pay so much tuition to learn martial arts are going to be happy, and they are excited to get close to this kind of big killer every day. Li Qing spat happily.

"Dad, this money is gone, and then you can earn it, as long as you can ensure your safety, it is worth spending more gold coins, you are always waiting to enjoy the blessings. Wait for you to use your personal mobile terminal to accept the highest control of the flying fortress, give my mother and me a second-level control authority, and Yu Zhifang is born with third-level permissions. ”

"No, how can I ask for the highest authority, this should be given to Aaron! Dad won't operate this big guy. Li Qing hurriedly excused himself and said.

"Brother Li Xian, you still take over the supreme command, the boss will go to the super ruins to experience in a few days, and there will be no time and conditions to control the flying fortress at that time, as for the problem of not worrying, the boss will install virtual intelligence for the flying fortress, and you can directly command by voice at that time." "Born to persuade.

"That's what Dad said by nature, my experience will take a year and a half, and when the child is not by your side, there is this flying fortress to guard, so that I can devote myself to the experience, Dad don't let the child worry about it!"

Li Qing finally accepted the highest authority, and after the flying fortress landed, the virtual projection appeared in front of Qianlong and others to teach how to hand over, this kind of thing Zhiqing'er explained how Qianlong operated during the day. Li Qing followed the instructions and connected the highest control authority of the Flying Fortress to the personal mobile terminal, so that he became the sole owner of the Flying Fortress.

In the lounge next to the large laboratory of the Datang Academy of Sciences, the prince and Yue Lan made the final confirmation of the research results of this ingots refining stock solution.

"The refining essence has reached its peak after the efforts of thousands of our people day and night, and I believe that with the current amount of knowledge in biology and genetics, ten times the refining efficiency is the best result that can be done at present, which is completely consistent with our prediction at the beginning. Yue Lan said affirmatively.

"How cost-effective is Aunt Lan, and when will it be mass-produced?"

"Ten times the need for two common third-grade spirit materials, plus any kind of third-grade demon beast blood, although the amount needed is relatively small, but according to the calculation, every 10,000 people need two kinds of third-grade spirit materials each, plus all the blood of any medium-sized three-grade supernatural demon beast.

It is not realistic to promote ten times the refining body liquid in the whole territory, and there is only five times the level that can be promoted, and the cost performance is the most suitable, and it is a common material that can make a refining catalyst. Yue Lan replied.

"Five times is not bad, this can already greatly accelerate the speed of body refining, who knows the final formula of Aunt Lan now? I can let the official secretly purchase the materials needed for the formula, but I can't let those profiteers disrupt the plan of refining the body." Li Yang asked with concern.

Do you think that Aunt Lan will only do experiments and research and development work, rest assured that all the final formula information is in my hands, and the final summary verification is verified by Aunt Lan herself, people with ulterior motives don't know what the result is, let alone know the final formula. Yue Lan gave the crown prince Li Yang a big roll of his eyes and said.

"Aunt Lan, I'm not worried, I don't need to say the seriousness of the matter, once it leaks out, it will really cause turmoil, and now in this special period, let civilians improve their strength faster, so that they can better survive in the next unknown crisis. Qianlong sighed solemnly.

"You don't have to worry about the formula, as for the crisis that you predicted from those veterans, it's ridiculous, there is no basis at all, and you still think about it as something that is about to happen, have you ever thought that there is no power that can see through the future, just rely on a few fortune-telling props?" Yue Lan asked disdainfully after assurance.
