If you can't figure it out, let go of it for the time being. There are many troubles in front of you, but Yao Xian did not intend to devote his extra energy to these unknown aspects.

Back at his temporary room, Yao Xianxian contacted his hometown and her lair.

Nowadays, two satellites in humans in the sky are knocked out from time to time, and remote communication becomes extremely unstable. Relatively fewer and fewer communication resources are given priority to the military, but the telephone contact between cities is still relatively stable.

He did not intend to use the precious communication channel, and it was not convenient for Yao Xian to contact him for several weeks, so he didn't know anything about his family's situation. Now that he has spare time, he naturally needs to communicate more.

As expected, Mo Hanmei complained a lot as usual, but things went quite smoothly.

The formation of the S7 mercenary army was still quite smooth. According to this time progress, at most half a month, the upper limit of the 30,000 troops of the legion will be broken. Now we have to consider the matter of selecting the best from the best.

Yao Lingling had already returned to Penglai College in advance to report her recent gains to the hospital. Her sister also conveyed the relatively stable status of Penglai College, which made Yao Xian feel at ease.

"The San San Demon Zone is relatively stable. The Martial Arts Academy has just been transferred back from the front line. The battle loss ratio is less than 4. The students are full of fighting spirit and are very effective in training. It is not yet time for the decisive battle. Brother, please concentrate on bringing Sister Natasha back first."

The environment behind it is good and there is no worries, so Yao Xian is determined to continue to stay on the front line of this insect area.

"Since that's the case... let's speed up the next step of practice. The hard bones are right in front of you. Before you get the information, you can improve as much as you can."

The front line of the insect area was originally expected to be even more dangerous, and the strong enemy without fear was more difficult to deal with than expected. Although the chaos of high-level demon insects is not difficult to deal with, the mass-produced medium and high-level demon insects are enough to exhaust the physical strength and internal energy of any strong man.

In the pursuit battle, Yao Xian killed a total of eleven natural disaster Murphy Zergs and four catastrophe demon insects with level 8 chaos. Their record was amazing, but behind it, they used frequent ultimate moves, exchanging injuries for life, and almost exhausted.

All internal energy was exhausted in the pursuit battle. If it weren't for the companions whom Yao could trust, Yao Xian would never have come back.

Of course, if it weren't for the drag of his companions, he would have teleported away continuously and would not have been exhausted by endless oil-adding tactics.

"Learn from the lessons... At the moment when the terrestrial realm is still very rare, quantity can easily overwhelm the quality. Besides, other people's top combat power has not yet appeared. It's strange, why is it useless? It's obviously a level nine power..."

Yao Xian would not be stupid. He would think that the Murphy swarm that could not move his doomsday powerhouses would not have doomsday-level war insects. If he wanted to go deep into the insect nest to save people, the peak powerhouse in the human realm, or even the super troubles of the half-step realm, would be the barrier that he had to cross.

Therefore, it is imperative to go into seclusion again, and to turn the accumulation of this period of time, combat experience and cultivation gains into real combat power.

After simply setting up the defensive magic circle and instructing the military to go into seclusion, and do not disturb yourself before getting Natasha's information, Yao Xian began his retreat practice.

In the life-and-death battle with Anya Li, he achieved a breakthrough and became a true innate warrior. Yao Xian's has been in natural disaster for three years.

Although three years of hard work, compared to those old monsters whose average breakthrough time is calculated in a hundred years, they are often stuck in bottlenecks until they die.

But since he turned around and rebuilt, the three years of his journey have gained, which are incomparable to those veteran strong men who have been in seclusion for decades.

Unlike those old-fashioned natural disasters that have been passed down intermittently, Yao Xian has a complete and detailed development route for his future route. Many of the bottlenecks stuck in key areas are just natural things for Yao Xian.

He didn't have to worry about getting into a stubborn and going into a dead end. From the beginning, after entering the natural disaster stage, he was building his own realm of the Heavenly Punishment Thunder Pool.

From a level 7 natural disaster to a level 8 catastrophe, it is to combine your lifelong learning and life experience, and turn the inside out into a real field, the work that belongs to your own world.

Domain power is the fundamental difference between catastrophes and natural disasters, and it is also the reason why catastrophes can easily crush natural disasters without domains.

Unlike other strong people who need experience and knowledge to build their own fields, and with experience in previous life practice, Yao Xian knew from the beginning that the templates and postures of the field that suit him the most, and he had a lot of time left to explore.

The existence of Penglai Immortal Island is even higher than the concentration of spiritual energy gradually thickened by the outside world, which has allowed his predecessors to accumulate internal energy, nourish qi and preserve momentum in dozens of times, and lay a solid foundation.

Now Yao Xian has reached the peak of the seventh level natural disaster and has gradually reached the threshold of the next step.

Coupled with the advantages of vision and experience, the construction of the most difficult-to-understand areas is extremely smooth. It is not wrong to say that it is the peak of natural disasters and a half-step catastrophe.

Yao Xian was able to defeat his opponent by relying on the large amount of internal energy consumption, more because he had a pseudo-domain that could fight against the realm.

However, using the moves of a level 8 strongman with level 7 power is equivalent to loading a car engine on a tank. It is good to be able to start, so don't expect to run as fast as possible.

This is a waste of money, and the power is discounted, and there are many problems.

But now, facing more and more difficult endless insect swarms, the consumption of pseudo-fields with a large range and a small range are becoming less and less than enough.

Therefore, it is urgent to take that critical step and become a true catastrophe powerhouse.

"Food is eaten step by step. There are enough troubles encountered in rushing forward... As much as you can build, you can count as much as you can. Even if you cannot form a complete field, you must at least build a pseudo-domain of the Thunder Pool that is not much worse than the Chaos Domain."

The two sleeves danced lightly, and the wind and thunder were scattered with swords. Three hundred and seventy-six feather crystal swords were suspended in the narrow room. The hissing lightning turned the whole room into a sea of ​​thunder and lightning.

With a light touch on your right hand, a large amount of clouds and true energy overflowed from a purple-lighted alchemy furnace. The purples and clouds in the room made people unable to see the current situation of the house, but the ever-increasing crystal sword and the illusory clouds made the standardized and templated hotel rooms become like clouds and fairy palaces.

However, Yao Xian was like a tourist who was dozing in the salt water of the Dead Sea, lying naturally in the clouds and thunder, as if he had fallen into sleep.

However, the clouds that were constantly pouring in and out of the five orifices of the face, and the crystal sword that flew to Yao Xian one by one, flashing light, showed that he was practicing in a deep mind.

The lightning was absorbed by Yao Xian, and the Yunxiao kit gradually lost its light, and this alternative natal magic weapon began to become dull.

The crystal swords that lost all the support for lightning and became dull were gradually melted by the clouds and mists. They were integrated into the realm of the Heavenly Punishment Thunder Pool and became the cornerstone and backbone of it.

Yao Xian used his natal magic weapon as the cornerstone and backbone, which greatly reduced the difficulty and time required for the construction of the domain, and also improved the affinity of the domain to the master and the damage to the enemy.

This is a different sense of trickery and shortens the accumulation time required.

However, Yao Xian is not the only one who uses the power to build the field with the help of natal magic weapons. Mo Hanmei is able to become a level eight-level strongman so young, and it is also a field built by the Thunder Whip.

Of course, it is not just that the rare treasures in the construction field can be obtained to turn them into magic weapons. What is needed is not just a simple time.

Yao Xian patiently integrated the crystal swords with his own field one by one, just like building a house, gradually building various steel skeletons and pillars, and then pouring cement and bricks into it.

Building a field means building a world that belongs only to oneself and not being careless.

This is a water-mix kung fu. When all the crystal swords are fused by the domain, it is the day when Yao Xian truly enters the catastrophe.

"All 376 have been fused 130... Try to fuse another 50 before the end of retreat. After half of the skeletons of the field are formed, you should be able to use some domain abilities. That way..."

A familiar face suddenly appeared before him. Perhaps, Yao Xianyuan attached more importance to an unworthy disciple who always sang against him than he had expected.

"………………If you save Natasha, you will have more chances of winning!" (To be continued. Please search for Astronomy, novels are better, updated and faster!)
