For now, the cave on the other side of the passage is safe, and the vultures are far away from the cave.

According to the information fed back by the explorers, the diameter of this aerial island is about 400 square kilometers, which is equivalent to half of Beiguang County, and the area where the vultures live is more than 100 square kilometers away from the cave.

Therefore, Gu Qing relieved to let all the collectors enter the Lingyun world, and then let the explorers be distributed on the periphery to be on guard, in addition to guarding against the group of vultures, but also to guard against other dangers that may arise at any time.

The cave was very large, and the spatial passage was opened on a huge rock, and after all the gathering sappers had entered the Lingyun world, Gu Qing also followed.

Standing in this world really down-to-earth, Gu Qing realized how wonderful everything was here, the true qi in his body seemed to be boiling, and it could flow automatically without even his traction, at first he was worried about going mad, but after a period of time, there was no discomfort at all, and because of the relationship between Lingyun, the already pure blood energy true qi in his body even had a tendency to be purified again.

When he was still immersed in the beauty brought by the spiritual essence, the system sent a message: "Host, the air here contains a very rich spiritual essence, and no harmful substances have been detected for the host for the time being, but for foreign beasts, it seems that it cannot be affected by spiritual essence." ”

When Gu Qing heard this, he frowned slightly: "Huh? Can't affect alien beasts? Could it be that the alien beast is immune to this kind of Lingyun? ”

If that's the case, it's really bad, in addition to Gu Qing's zombie army infected with the zombie virus, the corpse beast army, the skeleton zombie army and the terminator army that has not yet been officially produced, only the alien beast army belongs to the category of living beings, if Lingyun has no effect on the alien beast, then the effect of the alien beast army on Gu Qing in the future will definitely be reduced to a very low level, and some of his plans will also fail.

"I can't say that, I just can't react to the spirit that pervades the air in this world."

Gu Qing thought for a while, there were still three units of refining spirit essence in the energy oven, and said to the system: "Test it, find a combat type alien beast to fuse the refining spirit essence of those three units and try it." ”

After receiving Gu Qing's order, the system officially began to operate, and the sappers on this side were also busy searching for energy everywhere.

The collectors had already memorized the smell of red and white energy before, and after careful search at this moment, Gu Qing saw that many collectors were flying deeper into the cave, so he also followed in.

The cave was trending downhill, and Gu Qing could see that the rhizomes of many large trees were deeply rooted in the soil, like a tight network, entangled with each other and stretching into the distance.

Gu Qing frowned and looked at it, the trees in this world seemed to be a little more vigorous, the lowest height was seven or eight meters, and the height was even dozens of meters, and the underground rhizomes covered the range can be imagined, even if the trees on this sky island are not as vigorous as those on the ground, but they are not bad, I am afraid that the entire interior of the island is covered with these tree rhizomes.

Walking to the end of the cave, Gu Qing finally saw something that attracted the collectors, it was the red and white energy that flowed like an underground dark river, these red and white energy were not as distinct as the one left by Chang Hate Jun, divided into red and white, but mixed with each other, forming a red and white river, which slowly flowed deeper into the island.

At the same time, he also found that most of the rhizomes of those trees also extended into these red and white energy, which couldn't help but make Gu Qing have more guesses, it seems that the trees here are grown with red and white energy as nutrients, so they can grow so tall.

The sappers collected these red and white energy in an orderly manner, and then returned to the underground cavern of Shenlong Mountain Villa to inject it into the energy oven.

Gu Qing also walked back, and at this time, the production center had already completed the test of strengthening the spirit of the alien beast.

This is a humanoid beast, with a diamond-shaped head, the edges seem to be very sharp, the end of the arms does not have palms, but two long blades, the blades can be ejected out, the impact is very strong, at least a hundred meters range, the lower limbs are strong claws, and there is even a slender tail behind it.

The system said: "This was originally an intermediate-level alien beast, which belonged to the combat specialty, and the combat power was regarded as a middle-level alien beast in the current intermediate alien beast, and after the perfect fusion of the spirit essence of the three units, it had already undergone a combat test before teleporting to the host, and it was confirmed that it could completely defeat the top combat-type alien beast among the intermediate-level alien beasts." ”

Gu Qing said: "Oh? That is to say, the spirit essence refined through the ability oven can be used to strengthen the alien beast army, but the spirit essence that exists in the spirit world itself cannot be absorbed by the alien beast, do you know why this is? ”

The system said: "According to the analysis, it may be because the alien beast itself is a manufactured product, not a natural creature. ”

Gu Qingmo rubbed his chin and nodded: "Well, but fortunately, it can still be strengthened through the base, as long as there is enough spiritual essence, my World Destroying Legion will definitely be able to be reborn." ”

Then Gu Qing said to the system: "Let's do this first, recycle this alien beast, and then mass produce it after genetic locking, here not only do you need explorers and collectors, but you also need a certain garrison force to ensure the normal operation of this resource chain, and there are some unexpected situations, if you are discovered by the local natives whether they have the strength to kill it before it leaks out." ”

After the comprehensive selection, Gu Qing decided to use this strange beast, because it was fused with spiritual essence, it could completely defeat the top intermediate combat type beasts, and most of the top intermediate combat type beasts were huge, and it was not suitable to become a garrison here at this time.

But if you want to use high-grade alien beasts, the price of mass production is too expensive, even if Gu Qing has a large amount of kill points in the account now, but there are more places to spend money, and you still need to save some.

Only this strange beast was the most cost-effective, and in the end, Gu Qing named it Blade Warrior, becoming the third class option.

Things in the Lingyun world seem to have gradually stabilized, Gu Qing has already let the system produce a production center in this world, as long as the Lingyun is enough, there can be a steady stream of explorers, gathering sappers and blade warriors from the production center and put into the great cause of development.

All that is needed now is accumulation, and when Gu Qing has enough strength to eliminate the only threat on the island with the power of thunder, and that group of vultures, he can start large-scale development, accumulating more spiritual essence for insect eggs to absorb and hatch.

After the alien beast class system and the Zerg were mature, Gu Qing could prepare to make great strides to carry out his great plunder plan in this high-energy world.
