Zhang Mu walked around the mutant beast's corpse and began to look at the things inside the colorful light shield.

After seeing it clearly, Zhang Mu confirmed again that what was inside was the treasure in his memory, the mother-and-child gourd.

The old white fox seemed to have missed a trick. It thought that this defensive circle was enough, but unfortunately it encountered Zhang Mu and his team.

Even if they are mutant beasts at the peak of the first level, even if they have already become the kings of the first level, they are still vulnerable under the suppression of their level, and they still encounter freaks like Zhang Mu and the obsidian worm.

Even the mutant wolfhound, under Zhang Mu's generous feeding, has been fed with the purest earth-type beast cores. Until now, it has not eaten beast cores of other attributes that would affect the purity of the elements in its body. Therefore, the mutant wolfhound's use of the earth element is far stronger than those mutant beasts that rely purely on energy accumulation to reach the peak of the first level.

Looking at the corpses scattered on the ground, the Blood Vine Lotus had already begun to devour the corpses silently, and Zhang Mu didn't care anymore. These blood and flesh essences could no longer have much effect on the obsidian worms, and now they could only be provided to the Blood Vine Lotus.

Zhang Mu cast his gaze on the colorful light shield not far away and fell into deep thought.

The older the fox gets, the more cunning it becomes. Zhang Mu feels that its intelligence has surpassed that of a normal human. This is just an intuition. Even in the novels or myths of his previous life, foxes that become spirits are famous for their cunning tricks.

Although the dozens of mutant beasts just now were already very strong as the first line of defense, now it uses this light shield to protect the mother-and-child gourd. It must be its last resort and should not be underestimated.

Suddenly, the blood vine lotus shrank back, and a dozen vines placed a bunch of high-energy beast cores in front of Zhang Mu, signaling Zhang Mu to take them back.

This time, Zhang Mu woke up from his contemplation, subconsciously tapped the Era Merchant Ring, and put the beast cores into his pocket.

But now the sound of bombing outside the city has weakened a lot.

This is amazing! Zhang Mu felt that it should be the human army retreating. Time might not be enough. No matter whether Long Qi could deal with or delay the old white fox, when all the mutant beasts come back, Zhang Mu will miss the mother-and-child gourd in the colorful light shield completely. He can only escape with the help of the obsidian worm, and he also has to consider whether he will be seen by Long Qi or the white fox.

He looked at the shriveled corpse on the ground that had been sucked dry by the blood vine lotus, and suddenly an idea came to him. Until now, he didn't know what the defensive means of this colorful light shield was, so he decided to give it a try first.

Zhang Mu summoned a vine of the blood vine lotus and directly controlled it to pierce into a leather bag. He swung it hard and threw it into the colorful light shield.

What shocked Zhang Mu was that the moment the corpse was thrown in, it began to disintegrate.

Soon, the corpse turned into a ball of blood and essence, and slowly, as if by attraction, it was pulled towards the roots of the mother-and-child gourd.

Zhang Mu was stunned to see that under the exploitation of the Blood Vine Lotus, a body that had dried up to this state could still be squeezed out of all its value. Moreover, he did not see clearly how the colorful light shield could decompose it so thoroughly.

Moreover, Zhang Mu had a unique feeling that this might be the defensive ability of the mother-and-child gourd itself, otherwise the energy obtained would not flow towards the mother-and-child gourd after decomposition.

This made sense, why the old white fox hadn't gotten the mother-child gourd yet. Zhang Mu originally thought it was waiting for it to mature, but now it seemed that it couldn't break through the colorful light shield.

No wonder it was so confident staying here. It originally thought that even it could not break through the light shield, so there was no need to send too many troops to guard it.

So he threw in a few more bodies, but still did the same thing as before.

For example, the decomposed essence and blood condensate slowly flowed towards the mother-and-child gourd.

Zhang Mu didn't believe it, he still didn't see clearly how it was done. Even though he focused all his attention and concentrated all his mental energy, he didn't find the strange name of this power.

Looking at the corpses on the ground, Zhang Mu was also annoyed. He directly used all the vines of the Blood Vine Lotus and threw all the corpses on the ground into the colorful light shield one by one.

However, Zhang Mu still couldn't see clearly. Even if more corpses were thrown in at the same time, they would all have the same fate, being completely decomposed without leaving any trace.

"What on earth is this?"

Zhang Mu stamped his feet suddenly, looking at the colorful light shield, but he didn't dare to go forward. The thing that the leader of the second-level mutant beast couldn't handle was indeed too difficult to crack.

He tried to touch it with his mental power, but it was devoured without leaving any trace. He was so scared that he quickly retracted it. As for the wind blade of the obsidian worm, it couldn't cut it at all, and the earth spikes of the mutant wolfhound were ground into pieces the moment they left the ground.

He didn't dare to try using the Blood Vine Lotus. Energy attacks were fine, but if it came to physical contact, he didn't know what would happen. It was really no use. Zhang Mu felt that he had already used up all his strength, and he began to think of retreating.

"Xiao Hei, let's go. The complexity of the matter is beyond my imagination. It is not so easy to solve. Let's go. If the white fox or Long Qi comes, I will be in trouble. Since there is no way, forget it and go."

Zhang Mu turned his head and looked at the black worm that kept releasing wind blades and was unwilling to give up. It was even more stubborn than him and said.

However, Zhang Mu did not get the response he wanted. The obsidian worm remained silent, and after a while, it slowly sent this message to Zhang Mu's mind link.

"Look carefully, I feel that the color of the two gourds is darker, right?"
