Soon Nie Chen arrived at the Yanhuang Treasure House, and eight magnetic field weapons were packed and transported out. According to the Chief No. 1, four of them were fixed at the fixed location and buried deep into the ground.

The other four pieces were carried by four military aircraft, and the military opportunities flew across the country.

Assuming that the speed of a military aircraft is 1,000 kilometers per hour and a magnetic field weapon with an impact range of 100 kilometers, the area affected in one hour can reach 200,000 square kilometers.

Twenty hours, four million square kilometers!

In theory, the range of influence of four aircraft can reach 16 million square kilometers!

The territory of Yanhuang Kingdom is less than 10 million square kilometers, and four aircraft can completely affect the entire Yanhuang Kingdom in one day, causing all nuclear bombs within the Yanhuang Kingdom to be invalid! -

The areas affected by the four aircraft will overlap, but the minimum impact of those magnetic field weapons can reach 100 kilometers, and the total impact area is much more than 10 million square kilometers.

Therefore, as long as the plane does not fly randomly and is scheduled to fly, its impact can cover the whole country.

However, there is a problem with flying like this. If the plane flies past and the people from Tianyin Demon Sect arrive later, the nuclear bombs brought over will have effect.

Therefore, it is still necessary to have a level 4 magnetic field weapon. In the future, a level 4 magnetic field weapon must be arranged to affect all areas of the entire Yanhuang Kingdom at any time.

Time passed half a day without realizing it.

For half a day, Nie Chen was practicing in the Yanhuang Treasure House practice area.

"Siying, a semi-finished product of the fourth level, give it." Nie Chen said.

This four-level semi-finished product was built for nearly two days, and the length and width were about four meters, which was very complicated. If it weren't for Songdo Qing, the factory would not have been able to succeed in a year or two.

And even if it succeeds, the quality will be much worse than this.

"Siying, don't worry, it's a little damaged. Songdaoqing will not be able to recover after a long time." Nie Chen said with a smile.

It is very troublesome to make such a big guy, but it is easy to recover by just breaking some damage! And if it is produced by a factory, it will have to start over if it is damaged and it will take a lot of time.

"Um."

Guan Siying nodded. She was quite confident. Her understanding of this aspect has been greatly deepened during her time here.

An hour passed.

Nie Chen looked at Guan Siying, and slight sweat came out of Guan Siying's forehead. The level 4-level array was quite troublesome, but she had already reached the end.

As long as there is no problem in the end, Guan Siying, a level 4 magnetic field weapon, will succeed once!

One minute, two minutes... Five minutes passed, Nie Chen's eyes lit up, and he saw the light flashing on this magnetic field weapon, and he succeeded!

"call!"

Guan Siying let out a long breath and smiled on her face. When she started to do it, she was not sure, but the result was very good, and she succeeded!

Moreover, this level 4 magnetic field weapon is quite good.

Guan Siying estimated that the scope of influence exceeded one thousand kilometers.

It should be able to reach 1,100 kilometers!

What is this concept?

This means that the area affected by this magnetic field weapon can reach nearly four million square kilometers!

The population of Yanhuang Kingdom is concentrated in the central eastern part. This magnetic field weapon is well placed, which can benefit more than 80% of the entire Yanhuang Kingdom. With some third-level magnetic field weapons, it can definitely benefit more than 90% of the entire Yanhuang Kingdom.

"Siying, you are so awesome!" Nie Chen kissed Guan Siying excitedly on the face.

Guan Siying looked at Feng Yingtong and the others with a slightly red face. Although she had all had the closest relationship, Guan Siying and the others were still relatively shy.

"Nie Chen, the country does not intend to compromise with the Tianyin Demon Sect, right?" Guan Siying said.

Nie Chen nodded: "Of course! The Tianyin Demon Sect wants to get 20,000 spirit stones from me, and it is simply a delusion to get 50,000 spirit stones from our Yanhuang Kingdom!"

"Nie Chen, even if the nuclear bomb cannot be used, the Tianyin Demon Sect may use other methods to threaten it. It still has to solve this problem from the root." Guan Siying said.

Nie Chen nodded: "You are right, but the Tianyin Witch is everywhere. As the Yin Demon Sect is very powerful today, it is not so easy to solve it!"

"Using the rest of the methods to obtain spirit stones is not as effective as a nuclear bomb. If I were from the Tianyin Demon Sect, I would rather go to another place to threaten!"

Guan Siying nodded slightly: "That's true, if it's just an ordinary bomb or something, it's impossible to get a large number of spirit stones! They won't be so naive either."

"Siying, we did what we should do... You have a good rest, this is a very tired moment." Nie Chen said with some pain.

"It's okay... It's a pity that there is no semi-finished product anymore, otherwise I can continue. There were still some minor mistakes in some places just now, and the accumulated effect was much worse." Guan Siying said.

Nie Chen sighed lightly: "Siying, you are already extremely powerful! Even if I understand this aspect on this side, I will probably be able to create a second-level magnetic field weapon!"

"You are already level 4! Songdo Kei is working on the second level 4 semi-finished product, and the second time will be a little faster, but it will take a day later, so let's rest and practice first."

"I have to go back to Rongcheng now. The side of Rongcheng is in the central area of ​​Yanhuang Kingdom. This level 4 magnetic field weapon is placed there to benefit more people."

Guan Siying nodded.

Feng Yingtong suddenly came out of the Qing Emperor Cauldron: "Nie Chen, Shen Chenxue's parents, Bai Yun's parents, Li Zhengdao, Zhou Yi, and Luo Yang have all been strengthened and ended."

"Zhou Yi Luo Yang Li Zhengdao has reached the early stage of the Heaven Realm. Shen Chenxue's parents and Bai Yun's parents are now at the peak of the Earth Realm. This time they are a bit reluctant to directly strengthen to the Heaven Realm."

Nie Chen nodded slightly: "The peak of the earth realm is not bad. At least if a monster encounters danger, it will run faster than most people."

"Yingtong, it's not convenient for them to appear outside here directly. You can take me into the Qing Emperor Cauldron. I'll let them enter the Xiaoyao Ring and take them away!"

"good."

Soon, Luo Yang and the others appeared in the Xiaoyao Ring. Nie Chen left this side and headed for Rongcheng. The fighter plane was not comfortable. This time, Nie Chen did not drive the fighter plane and left on his special plane.

Inside the Xiaoyao Ring.

Luo Yang and the others were training, and their strengths were greatly improved. If they didn’t train well, they would easily injure others, and their combat power might be much lower than their cultivation level.

In the past, they had low strength, and there were formations for practicing in the Xiaoyao Ring. These were extremely secret matters and could not be passed on from outside. Therefore, at the beginning, Guan Siying and the others did not enter the Xiaoyao Ring to practice.

Nowadays, with the continuous improvement of strength, this issue is gradually no longer a big problem.

With Nie Chen's current strength, even if Ice Emperor and the others know it, so what?

Of course, Nie Chen tried his best to keep it confidential. It was impossible for Luo Yang and others to say about the Qing Emperor's Ding to refine the body and the training space inside the Xiaoyao Ring.

Luo Yang and the others have been hypnotized and will not disclose information about this.

Moreover, even if a powerful man caught them for hypnosis, it would be extremely difficult to know the information about this. Guan Siying took action to hypnosis.

Although Guan Siying is only half a step into the Dan Realm, her ability in this area is even stronger than Nie Chen.

"Everyone is working very hard." Nie Chen smiled slightly.

The next second, Nie Chen's spiritual sense scanned Han Yushan.

"Nie Chen, kill me, kill me!"

Han Yushan wailed weakly. Since he was arrested, Han Yushan has been in pain. Sometimes he fainted, but it didn't take long to wake up again.
Chapter completed!
