The Mother Emperor, as the most critical combat unit of the Zaka Zerg, is strictly speaking, just a creature that acts according to a fixed program, much like a computer in Earth technology. The Mother Empress herself does not possess the same intelligence as humans. If the Mother Emperor is left to act freely without any external interference, then everything it does will only follow the principle of colonization with the most efficient action.

Therefore, theoretically speaking, the Mother Emperor herself will not make the move of transforming or even strengthening the creatures of the other planet, because the gene pool of biochemical creatures carried by the Mother Queen herself already has enough combat creatures to cope with all situations and have the highest efficiency, and there is no need to waste energy to transform and strengthen the creatures of the other planet.

Unless, there are other creatures with higher intelligence who are manipulating the actions of the Mother Emperor.

The first thing He Zhiyuan thought of was the high-level Zerg.

The high-level Zerg are the rulers of the Zaka Zerg, they are very few in number, but they have a high intelligence that is completely different from the mother queen. If there is a Mother Emperor and Zerg base in this Great Terre Valley, then it seems that it is very normal for one or several more high-level Zerg to appear.

If He Zhiyuan's guess is true, then the situation of these human teams in the Great Valleys is extremely dangerous! If these mutated Qingfeng beasts are just the mother emperor's independent resistance when she discovers that there is an invasion of foreign enemies, then the human race can still have a chance to win, because the mother emperor only acts according to the degree and resists the invasion by instinct, and does not analyze the strength and weakness between the enemy and us. But if the Mother Emperor's behavior is controlled by a high-level Zerg with advanced intelligence, then the situation is completely different. Since this high-level zerg who has been dormant for a long time has made a move, he must have the certainty of victory!

As if to confirm He Zhiyuan's conjecture, as soon as this group of larger, large-scale mutant Qingfeng beasts joined the battle group, the situation immediately took a sharp turn for the worse.

These large mutant Qingfeng beasts are not a little stronger than the ordinary mutant Qingfeng beasts. In addition to having higher offensive and defensive stats and faster speed, these large mutated Aominemon have also evolved extremely terrifying corrosive acid attacks!

The vanguard of this group of large mutant Qingfeng beasts first rushed to the left side of the human team, and at the forefront in that direction was the old man who used the heavy sword of the Beast War Association, one of the three top masters who had appeared in the Beast War Association at the moment.

In the face of these guys who were much larger than ordinary mutant Qingfeng beasts, the old man didn't dare to slack off, he let out a loud shout, and swung the heavy sword in his hand and slashed continuously, instantly condensing more than a dozen light curtains in front of him!

The faces of the large group of adventurers who followed behind the old man also changed from nervous to calm. You must know that just by using a light curtain before, it blocked the bite and impact of dozens or hundreds of mutant Qingfeng beasts, and now although these guys are a little bigger, their strength is estimated to be one or two times stronger than ordinary mutant Qingfeng beasts, and more than a dozen light curtains are enough to resist these guys for a long time.

Then, in the calm eyes of everyone, this small group of large mutant Qingfeng beasts that arrived first launched an attack on the more than a dozen light curtains in front of them. Instead of the impact and bite that people expected, the large mutant Qingfeng beasts opened their dark mouthparts at the same time, spewing out a large pool of caustic green acid.

The sturdy light curtain that could resist the simultaneous impact and bite of dozens or hundreds of mutant Qingfeng beasts was as fragile as if it did not exist in front of these corrosive acids! More than a dozen light curtains shattered into a pile of glittering fragments one after another like glass, and the corrosive acid in the big beach was almost not consumed and hindered in the slightest, and it pounced on the human beings hiding behind the light curtain like a torrential rain.

Unexpectedly, these dozen or so light curtains would be so vulnerable The human team suddenly wailed, the miserable green corrosive acid was both fast and covered an extremely large area, it was already extremely difficult to dodge, let alone in a sudden situation?

Almost all of the human teams hiding behind the light curtain were hit, and in just a few minutes, the terrifying corrosive acid corroded these people, even the belt bones, and even the human belt equipment into a pile of acid water! The area covered by the acid was almost instantaneous, and even the ground was corroded into a huge hole.

At this moment, everyone's faces had a look of panic. A group of flying demonic beasts that were overwhelming were already very difficult to resist, and if these monsters rolling in like dark clouds had an invincible corrosive acid that could pour down like a torrential rain, it would be a disaster! No one could escape such an attack!

Before they even had time to shake their hearts, this small group of large mutant Qingfeng Beasts that had annihilated an entire human phalanx had already stopped and crashed headlong into another human phalanx at a speed that made it impossible to retreat and dodge.

That small phalanx was a Vajra formation formed by about a dozen Cangyue Palace disciples, as well as five or six Guiyun Sect disciples who were assisted by them. When this small group of large mutant Qingfeng beasts collided, everyone in this phalanx couldn't help but let out a frightened scream - they didn't think that they could be stronger than the human phalanx with a master old man in charge.

But what people didn't expect was that this small group of large mutant Qingfeng beasts actually did not use their terrifying corrosive acid again, but swooped down and used their scale armor and forelimbs to engage in hand-to-hand combat with humans.

"The acid of these monsters must only be used once in a short period of time!" "The human elites present were all experienced in combat, and there were naturally many people with great vision and dexterity, and immediately some people guessed the flaws of these large mutant Qingfeng beast acid attacks, and shouted loudly, boosting everyone's morale.

This inference was obviously the most plausible explanation for the behavior of the large mutant Aominemon, and it also allowed the panic that had spread through the crowd to be slightly contained. The human phalanx, which had already been entangled with the large mutated Aomine beasts, also began to resist tremblingly, and as expected, as the people who shouted just now, these monsters just swooped down one by one to fight the humans hand-to-hand, and did not use acid to attack again.

In terms of hand-to-hand combat ability alone, these large mutated Qingfeng beasts are several times stronger than ordinary Qingfeng beasts, but this is not unstoppable.

"Those who have long-range weapons, those who can summon soul creatures, all rush up to block those big monsters, and can't let them rush in!" The voice that shouted just now sounded again, and suddenly everyone woke up, the most important thing at this time was not to kill the monster in front of them, but to block the large mutant Qingfeng Beast that still had the ability to attack with acid in the distance! The only weakness of the acid attack was probably the range.

Someone in the well-trained human team immediately turned their bows and crossbows and began to prepare to intercept the large mutant Aominemon in the distance, and those soul creatures that were not afraid of acid also began to shake off the Aominemon beside them and head into the distance.

"Whoa......" And at this time, more large mutant Qingfeng beasts had also arrived quickly.
