The eight- and seven-level underground beasts on the periphery were all staring at the mutated level-6 underground beast, and at the same time some subtle changes occurred in their auras.
If everything was calm and nothing unusual just now, now every breath has begun to converge and hide. Generally speaking, if a beast or human being deliberately restrains its aura and hides its presence, it will either be ready to start hunting or prepare to make other reactions.
However, they did not take action right away, as if they were still waiting for something.
"The other high-level underground beasts began to put away their breath, and they were ready to take action." The people watching from a distance also noticed the changes in those high-level beasts.
"But they seem to be waiting for an opportunity."
"What are they waiting for? Are they waiting for the promotion of the sixth-level beast?"
"Maybe that's the case, maybe there are other circumstances."
Everyone began to speculate on various possibilities for this situation.
And just as the humans at the base were staring at the overall situation over there, the high-level underground alien beasts over there were staring at the killing alien beasts, as if waiting for an opportunity to appear.
Qian Xiaoai and others vaguely felt that there would be no emergency so soon, but there would definitely be some special situation later.
However, the wait turned out to be three or four days.
Before the first six-level underground creature started to advance, other advanced beasts appeared. There are different levels, from level six to level three or four, etc.
And those high-level underground beasts have finally stopped sitting quietly and watching in the past few days, because they have begun to take action.
For example, a level 4 underground beast was in the process of advancing, and a level 5 underground beast suddenly appeared from the side to attack it. So at this moment, among the seven- and eight-level high-level alien beasts watching from the outside, a level-7 one suddenly jumped down and instantly pounced on the level-5 underground alien beast that was about to attack.
Because when the fifth-level alien beast that was preparing for a sneak attack had just taken action, it attracted the attention of those high-level underground alien beasts. Therefore, with two levels higher strength, the speed, movement power, precise reaction, etc. of the seventh-level underground beast are much stronger than those of the fifth-level underground beast.
So before the fifth-level sneak attack could succeed, the high-level underground beast had already pounced him down and pinned him down under his claws, and was bitten to death before he could react.
The level 5 underground beast that was bitten to death in this way, the level 7 underground beast that bit it to death, did not eat it, but threw it there and turned around and left.
Soon, this fifth-level underground beast will be picked up and eaten by other beasts that have no opponents yet.
So it can be seen from this point that these high-level underground beasts seem to be doing guard work to maintain order. Of course, they should not only do this, there may be other things.
While humans were speculating on the meaning of the actions of these advanced underground creatures, they finally waited until one was ready to advance.
That piece of land was already covered with scars and was destroyed in a mess. The strong smell of blood filled the air, and the roars of beasts were still noisy and intertwined.
And this one that has been promoted is not the first level six underground beast, but a level five. It successfully advanced to level six, and the aura on its body suddenly increased, and its body began to stretch and deform with a crackling sound.
Soon it entered the ranks of the sixth level, but then it did not continue to join the ranks of killing each other, but turned around and quickly left the field.
Those senior people didn't stop it and left with it.
However, after another one failed to advance to level 5, its aura became chaotic and somewhat uncontrollable. Then the energy in his body began to shrink and then grow sharply, shrinking and then rising. This means that its promotion has failed, and its next outcome will be a direct energy explosion and death.
The energy explosion will not explode their entire bodies, but it will deform their bodies somewhat.
After this fifth-level promotion failed, the surrounding fifth- and sixth-level underground beasts that had been waiting for the opportunity immediately rushed forward. Whoever gets there first gets another round of chaos.
But such a situation is allowed, and no advanced underground beasts will appear to stop them.
However, when a sixth-level underground creature failed to advance, the surrounding underground creatures did not dare to rush up and grab it. Anyway, even if they rush up, they won't be able to grab it, because there will be a level seven underground beast that is faster than them.
The surrounding seventh-level underground beasts seemed to be waiting for this moment, but those of the eighth-level ones did not move. However, the number of eighth-level underground beasts appearing here is not large, only one-tenth of the seventh-level ones.
And those who successfully advanced from level 6 to level 7 did not leave like those who successfully advanced from level 5 to level 6. They will move to the edge of the battlefield and continue watching.
"Doesn't it mean that the highest level can only be broken through to the seventh level? Don't these seventh levels need to be promoted in the same way as those?" After watching it for a few days, Luo Yuanjun also said in confusion.
"Perhaps the seventh level should be a special level. Maybe they will use another way to advance. But this method must be the same as killing each other. After all, even if they eat this one on the ground now, Even if you breed a seventh or eighth level mutant beast, you won't be able to advance." Li Yueshan said next to him.
"Do they count as internal consumption? I thought these things have no natural enemies and will continue to wreak havoc on the surface of the earth. In less than ten years, the entire earth will become a Death Star." Qian Xiaoai said with emotion at this time.
Although their base and Haicheng have recently been researching a herb that is very effective against these underground creatures, the number of these ghosts is still there. Even if humans have herb that is effective against them, it will take decades to eliminate them all. Came down. After a few decades, we don’t know how many mutant plants, mutant beasts, zombies, etc. will be left on this earth.
After considering the future of the entire earth, the emergence of these things is even more terrifying than the impact of zombies that not only eat people, but also eat their own kind.
After all, zombies only eat people, they don't eat plants.
If there are no more plants, then the various biological chains on the earth will only become disconnected. If this continues for a long time, wouldn’t the earth really be doomed
