"It's amazing, not only can't you see what is inside, but your spiritual power can't detect it, it will pass by, and you can't explore the actual situation."

Wang Dong probed and couldn't help but change his face.

Gao Ming stretched out his hand and pressed it, and a rebound force appeared, shaking his arm to pain, and he said unexpectedly: "There is also a special defense, amazing." ”

"Let's go, this time I will go back and upgrade the base to this formation, which will cover a larger area, but it will take a lot of effort."

Xiao Mu was not prepared to let people stay here, it was enough to have a formation to protect it.

Everyone took a flying car back to the base, did not come back for more than a month, the base has changed a lot, the previous stone wall has been poured on the original foundation, reinforced concrete, the defense has been greatly increased.

In the wall, a lot of modern weapons are arranged in the holes, although there are no large missiles, but small missiles, laser shells, machine guns and the like are already available, which are enough to deal with ordinary insects.

"Modern weapons are powerful, but they can be easily dodged except for lasers, and most of them can only threaten aliens below the third order."

Xiao Mu shook his head, unless it was a nuclear bomb and carpet bombing, when attacking alone, the disadvantages of modern weapons were obvious.

"We can continue to develop laser weapons, one at a time."

Xiao Li'er was a little unconvinced.

"Yes, it can be like this, but the laser is too energy-intensive, and it may not be used when it is developed."

Xiao Mu pointed out the Achilles' heel of laser weapons, because of the need to condense the power of the rays, the energy consumed is very terrifying.

And these energies are not like explosives, which can be stored for a long time, and it is difficult to replenish them in time when they are used up.

"All that's left is hand-to-hand combat." Xiao Li'er wrenched her fingers, a little helpless.

"Martial arts evolution is the mainstay, supplemented by technology, this is the only way out, so you all work hard, otherwise the next crisis, your lives will be in danger."

Xiao Mu glanced at everyone, everyone's hearts were slightly cold, and they subconsciously became urgent.

"Wow!"

Rhubarb jumped on the city wall and wagged his tail, like a golden lion, his body was already more than a zhang high, reaching five meters, which was much larger than the size of the same level of alien insects.

Seeing the sharp flickering in the big yellow eyes and the condensation of the aura, Xiao Mu knew that the other party had successfully broken through, condensed the inner dan, and completely embarked on the path of alien cultivation.

"Starting today, upgrade the formation of the base, and strive to upgrade to the second order within a year."

Xiao Mu waved his hand and ordered the next big thing, that is, to upgrade the formation.

Under his guidance, the base began to refine the Yin and Yang Reversal Array.

Since the base was larger, more than ten times larger than the area under the canyon, the required array eyes were naturally not as few as eighty-one.

Xiao Mu first asked people from other bases to come over to learn how to refine the new formation eye, and then went back to prepare.

There is no way, the diameter of the base is more than 400 meters, and the array eyes required are as many as thousands, which cannot be completed in a day.

Under normal circumstances, the best material for the array eye is naturally the second-order alien wood, but unfortunately the alien fruit is not enough, where is it willing to cut down the tree to make the array eye, so it is refined with the bones of the second-order alien insect.

There are not many second-order insects, and there are only about a dozen in stock in the major bases, and Xiao Mu's base here is a little more, but there are less than thirty.

He arranged the bones of third-order insects to protect the fourth-order insects in the canyon, and they were small enough, if they used second-order insects, it would take at least ten to refine eighty-one pieces, which was not a failure.

The inventory of the base is still too far from the amount required to arrange the base, and the major bases need at least a hundred second-order alien insects to be enough, so they can only hunt second-order alien insects while refining, and strive to complete the upgrade within a year.

Fortunately, the different levels of the reversed Qiankun formation are of the same origin, and they can be upgraded little by little, and they don't have to be completely prepared in one go.

Every time a batch of formation eyes is refined, the formation power of the major bases will increase a little.

The power of the formation was increasing every day, and it was only a matter of time before it reached the second order.

Once the second order is reached, the power of the formation alone is enough to resist ordinary insects, and with the assistance of modern weapons, the defense of the base will be a little stronger than that of the heavenly city.

As for arranging the second-order reversal formation for the Heavenly City, it is basically impossible at this stage, the area of the Heavenly City is more than ten times larger than the base, and the required array eye is not ten times higher, but a hundred times higher.

He could only arrange the first-order formation first, and then slowly upgrade later, even so, it took a month to complete, and the rest still had to be done slowly.

Fortunately, Xiao Mu's upside-down Qiankun formation system has been promoted, and more and more cities have begun to adopt it, but it is not so simple to learn it, so many cities have offered him a high price to arrange the formation.

At this time, Xiao Mu was not in the mood to do this for the time being, so he sent his men who would arrange the formation to assist, so that he could also earn a lot of resources.

His attention was now on the cities that had been destroyed by the insect infestation, and it had been more than three months since the first city was destroyed, and the survivors inside were in terrible condition.

Many cities even offered to sell themselves for help, but unfortunately no one dared to save people, because everyone was facing the threat of insect infestation at the moment.

According to Superbrain, there are more than 10,000 insect tides on the earth today, and there are an average of 30 around each city, but fortunately, most of them are in the wilderness, and they are generally only a single digit close to human cities.

But even a single-digit insect tide has made human beings miserable, and the most powerful of them is Tiancheng, who only dares to hunt insects within a hundred kilometers nearby, and out of a hundred kilometers, the density of insects will increase greatly, and they dare not go out at all.

Humans should be glad that these insects are also victims, and they were thrown by the Eight Royal Clans, and most of them were not ordered by the Eight Royal Clans.

Only a small number of alien insects that have been controlled by the eight royal families in advance and have been driven by distraction will attack humans, which is why only a single percent of the insect tide besieges humans.

After all, this is a very good habitat for alien insects, and there are not many natural predators, so why bother to fight and kill? Therefore, even if most insect tides are formed, they are just developing separately and occasionally competing for resource territory, just like in the other world.

And the eight royal families are different, they want valuable things in the hands of human beings, and if they want to get the cultivation civilization of this star, they will want to destroy the city.

Xiao Mu knew these truths, so he had the idea to save the destroyed city.

Because he knew that as long as he killed the third-order alien insects, in a short period of time, the eight major royal clans would not have so many third-order alien insects that could be controlled, so they would naturally not be able to launch a counterattack quickly.

The insect is still smart, if it is not controlled from the beginning, how can it choose to be driven by a distraction that is not too strong.

"Prepare the materials for the first-order reversal formation, and tomorrow we will set off to save the survivors of this city."
