The two of them naturally would not refute Bai Mo's decision, or it should be said that they had the idea of taking a risk to find out from the moment they noticed the change in aura.

The two mechs swept into the distance one after the other, bringing up the yellow sand all over the ground, and by the time the yellow sand landed, they had long been out of sight.

Most of the Zerg were slow to react, and they deliberately avoided it, so it didn't cause a big stir.

But Lu Mobai still stopped perceptively.

"What's wrong?" White ink stopped at her side.

"Something isn't right." Lu Mobai manipulated the mecha to check the surrounding situation, "I have been to the border a few times when I was a child, and I have seen a lot of Zerg, and the Zerg here seem to be bigger. ”

"Bigger?"

"Well, the body length of adult soft-shell insects like the one over there is generally within two to four meters, and about three meters is the most common, but there are no adults here below three meters."

Bai Mo looked in the direction she was pointing, and a large gray worm close to four meters was wriggling towards them: "Could it be because of the aura?" ”

"Maybe."

During the conversation between the two, Yan Hua had already jumped out of the cabin and walked towards the soft-shell worm, but in just a few breaths, there was an extra gray crystal nucleus in his hand.

He returned to the cabin: "You can really feel a little aura in the crystal nucleus. ”

Lu Mobai asked: "What about those crystal nuclei before?" ”

Yan Hua shook his head: "No, none of those." ”

Bai Mo: "Maybe it has something to do with the concentration of aura. Let's look deeper, if not, we'll go back. ”

The three of them continued to go deeper, but this time they were not as busy as before, but cleared the Zerg as they went.

Bai Mo's guess was correct, as the concentration of aura increased, the number and volume of the Zerg increased, and the aura in the crystal nucleus also increased.

Thankfully, not all Zerg can be affected by the aura, at least only one or two of the ten they encounter.

After clearing out a clearing again, the three of them decided to leave, after all, there were only three of them, and the Zerg army in the depths was no longer something they could deal with, although they did not find the source of the aura, but with the discovery of the Zerg mutation, it was not empty-handed.

They told the soldiers guarding the border about this discovery, and hurried back to the school to report the situation, and by the way, Lu Mobai also told his old father.

Of course, they concealed the presence of Reiki.

There was nothing trivial about the Zerg, and the decision-makers at the top quickly responded and immediately launched a series of policies to strengthen military training.

Although the people at the bottom did not know what was happening, they could feel the tension of the atmosphere.

However, this did not have much impact on Bai Mo, except for a few times asked by the principal and teachers at the beginning, the rest of the time they were going to school step by step.

Time is half a year, the aura of this world has spread to every corner, Bai Mo they are quite stable in the military academy for half a year, in addition to class practice, is to go to the mercenary union to take over a little inspection task, dangerous things do not need them, the flowers and bones of the motherland, so the days are calm like a lake.

Until the news came from Xiaobai, who had disappeared for a long time.

I don't know where it has gone these days, but when it came back, it was a big circle, standing on Bai Mo's shoulder and chattering non-stop, which made her shoulders sore.

"Do you see where the spirit beast appeared?"
