Next, Xiao Mu took the Faun and others to familiarize themselves with the six nodes, and after a few people wrote them down, he taught them the operation methods.

"Faun, you try."

Xiao Mu pointed to the node, as long as there is one person in the church, the people of the major forces here don't want him to care.

"Hmm."

The faun nodded, walked to the node, and a white light appeared in his palm, and he gently placed it on the ground in a circle specially drawn by Xiao Mu.

After the power of light was injected into the ground, the white formation on the circle began to absorb his power.

In fact, with the strength of the third order of the Faun, it can only be regarded as a drop in the bucket for the formation of the Bright God Ruins at this moment, but the formation is a leverage, and the Faun God injects a point of strength, which can assist the formation to absorb more aura, and the power is ten points.

This is the terrible nature of the formation, as long as you understand the formation, you can easily mobilize ten times your own strength, so that you can cross a class to fight the enemy.

That is to say, the third-order can play a role equivalent to the fourth-order existence under this formation, if the fourth-order natural energy can be comparable to the fifth-order effect, if there are six fifth-order sits in this ruin, even if the king comes, he will not easily open it.

In Xiao Mu's heart, this is much safer and stronger than a city, enough for humans to have enough self-protection power when the alien ontology descends in the future.

The premise is that it can't be broken, otherwise there is nothing.

After the Faun God injected strength, the light of the entire formation was slightly brighter, and it was obviously effective.

"Next, you try to inject power in turns, to ensure that it can speed up at any time to regain its strength, if it can fully recover, it will be difficult for those guys outside to break through."

Xiao Mu spoke, with the passage of time, a large number of third-order masters have emerged from the major forces in Europe, and there are many who are in line with the restoration of the formation here, which is enough to rotate.

"Understood, but the other three points have to be handled by your people."

The Faun did not forget this until this time.

"You are worried, I am not a person who eats and drinks for nothing!" Xiao Mu shook his head helplessly, there were already hundreds of third-order people under his command at the moment, and he still lacked this manpower?

He turned around and called Ding Yongyuan and the others out and said: "In the future, you need some people to be on duty to cultivate here, to maintain the operation of the formation, three groups of people every day, three people in each batch, in turn, if you encounter a large-scale attack formation by an alien race, you must do your best to assist those guys to strengthen the formation, and you can't let this place be broken, otherwise our God Killing University will have one less place to cultivate." ”

Xiao Mu explained simply, and asked Ding Yongyuan and others to try to inject strength into the node they were responsible for, so that this operation could be over.

After doing this, he left straight from the tunnel and returned to Huaxia.

At this moment, the attention of the various ethnic groups was gradually attracted by the Miao Jiang Poison Land and the Netherworld Yellow Spring, which contained greater value, and began to invest a large number of people to investigate, but the result was still heavy casualties, but they still found out something, and determined that there were indeed more valuable relics in these forbidden places.

This turned their fear into a frenzy, and they didn't care about this attrition, but they didn't enter on a large scale, but stationed nearby, choosing to occupy the territory first.

However, the area of these forbidden lands is very large, and since the manpower of one clan is simply not enough at this moment, it is destined to be difficult to occupy, so that all clans can send people to investigate.

After the failure, those who originally wanted to compete for the relics of the God of Light also began to focus on these two relics, and as for the relics of the Earth Emperor, the various clans were at a stalemate for a while, but they were the quietest.

"Brother, it's not good, one of our transport planes was destroyed, and it was the hands of an alien race."

Not long after she came back, Xiao Li'er came over in a little anxious.

"What about people?"

Xiao Mu's face changed slightly.

"Dead."

Xiao Li'er sighed: "I don't know what those aliens are doing with our transport plane, and they can't use the materials on it." ”

"It's just curiosity, if it's us, when we see this kind of thing, we might also explore it."

Xiao Mu shook his head, not too surprised.

"But doesn't this incident indicate that the air will not be safe in the future, after all, there are more and more alien races, the more likely they are to destroy the transport plane, and we will lose a lot of resources."

Xiao Li'er said slightly heavily.

"It's inevitable." Xiao Mu nodded, this situation was also in the previous life, and even later when the alien race did it to humans, it was difficult for the flying machine to leave the city too far.

"Land transportation is more dangerous, air transportation will also be affected, and it will be very troublesome for our major cities to circulate resources in the future."

Xiao Li'er became sad, resources can be circulated, in order to give full play to the effect, once the connection is broken, the major cities will become isolated islands.

"There is also a solution, which is to build a transportation network underground, like the two tunnels we are currently building."

Xiao Mu shook his head.

"The price is too great, if you want to not be detected by the aliens, you have to be at least a hundred meters deep, like the two leading to the ruins, it is hundreds of thousands of meters, it took a lot of resources to build, we can't afford it."

Xiao Li'er's eyes widened, feeling that this method was too difficult, even in the previous earth era, the cost of building a subway per kilometer was hundreds of millions, even if the current level of science and technology has improved a lot, but if you want to open a tunnel in hundreds of meters underground, the cost is also very large, and it costs hundreds of millions of points to spend one kilometer, which is enough to kill 10,000 alien insects.

And the insects killed by the entire human race in a day are only about 100,000, that is to say, even if these resources are converted into tunnels, it will be about ten kilometers, more than 3,000 kilometers a year, in fact, most of the human beings themselves consume, and there is no way to leave so much.

"With the current savings of human beings, it is not realistic to build tunnels in major cities, but some main roads can be built."

Xiao Mu looked at the situation for a while, and finally decided to build tunnels between the major main cities, and he planned to gradually make a tunnel network to connect the ruins and cities, so that he could not only monitor his own situation, but also facilitate the circulation of resources.

"Brother, you're not kidding, this is just like the dungeon back then, you have to exhaust all the resources of the human race, and if it is discovered by a foreign race, it will be easily destroyed." Xiao Li'er didn't quite agree with this choice.

"Just take precautions, and even if you destroy it, it won't all break."

Xiao Mu shook his head and made up his mind: "Let's build the tunnel network between the six major cities of Huaxia first, I don't care about the other regions for the time being, my nest must ensure the circulation of resources, so that it can become monolithic." ”

Originally, he didn't think much about the tunnels, the tunnels of the two ruins were built to make use of the ruins, each of which was more than a hundred kilometers long and connected to the nearest city.

But when the transport plane was destroyed by aliens, he thought of the situation in his previous life, this time the human race still has some resources to use, and it is necessary to establish an underground network to ensure the circulation of resources in future wars.
