This efficiency, I don't say.

However......

Although the zombies in front of them were frozen, the zombies in the distance also blocked the way of the two people.

And the low roar in the tunnels has not stopped, which means that there are more zombies rushing towards them in the deeper places.

Seeing this, Xia Lu no longer hesitated, took Han Xiao's hand and said, "If you can't finish killing, rush over first!" ”

He opened the spatial barrier and wrapped the two men, and the figure quickly rushed to the depths of the crypt.

Click, the spatial barrier swept ahead, smashing all the zombies frozen into ice sculptures to pieces.

After a while, the world of ice and snow disappeared, and it entered the tunnels filled with zombies.

The more he rushed inside, the more zombies there were, and Xia Lu almost used the spatial barrier to push a bunch of zombie corpses forward.

At this time, Xia Lu's speed slowed down, and the pace of progress became more and more difficult.

"Protect me!"

At this time, Han Xiao suddenly said.

Xia Lu looked at her suspiciously, but saw that her eyes suddenly glowed white.

He realized something and hurriedly opened the spatial barrier.

The moment the spatial barrier disappeared, Han Xiao suddenly raised his hand, and an angry ice tornado roared forward.

A powerful cold snap filled the tunnels, as if time was about to freeze.

An ice tornado of biting cold winds and countless ice picks froze everything in front of it, and then swept the shattered ice forward like a flushing toilet.

Call......

The howling cold wind lasted for two minutes before it stopped.

After the cold wind dissipated, Han Xiao's hands hung down weakly, and his body seemed to be drained of all his strength and collapsed to the ground.

Xia Lu hurriedly helped her up and blocked the two of them with a spatial barrier.

At the same time, he was extremely surprised.

When she first met Han Xiao, the level of her abilities was many times stronger than now, but at that time she didn't have anything to do.

How could she use such a little ability, she can't do it.

In other words, the current Han Xiao has cut off the connection with those above and can only use his own abilities.

Han Xiao, who was supported by Xia Lu, was panting, her body was as soft as cotton, and she couldn't hold it.

Xia Lu had no choice but to squat on the ground and let her sit on her lap.

"Don't stop, the next wave of corpses will come soon."

Han Xiao was angry, but he still urged the next road to hurry forward.

There was no other way, Xia Lu had no choice but to take her whole person on her shoulders and continue to charge into the depths of darkness.

Inside, the ground beneath my feet became more and more slippery.

Moreover, Xia Lu clearly felt that the soles of his feet were softer, and the wall in front of him was no longer covered with a film, but a wall of flesh and blood.

This wall of flesh is different from the phagocytosis xenomorphs, not a single city, but a spiderweb-like segment, like the musculature growing out of the body of a giant creature.

This had to surprise Xia Lu.

It takes a long time to grow so many hyperplasias, at least a month or two.

In other words, before he arrived at the Suppression Tower last time, there had already been a corpse owner infiltrating the Suppression Tower.

What the hell is the corpse master doing in the Zhensha Tower for so long?

Continuing inside, they were again confronted with a wave of corpses.

However, this time there was a much smaller wave of corpses than last time.

Han Xiao could no longer fight, and Xia Lu could only rely on himself to keep rushing and killing.

Fortunately, the number of corpses is small and does not cause road congestion.

In the roar of the zombies, Xia Lu killed all the way to the end of the road.

A strange dark red light shone in front of him, like the huge mouth of some terrifying beast.

After a rush, he finally arrived at Yongdaokou, and the scene in front of him shocked Xia Lu.

Beyond the corridor is a large space that resembles a vase-shaped space formed by metal and rock.

In the middle of this space is a large metal structure in the shape of a cone, like a machine.

The upper end of the machine reaches the top of the space, and the lower end extends to the bottom of the space.

And on this machine is covered with a layer of biological constructs.

The structure is like a structure created by a machine, which is closely connected to the machine, and the original structure of the machine is changed, and other structures are grown in some operating parts.

There are a lot of bumps on the walls of the space and the machine growth, and zombies are hatching inside.

The metal surface of the machine was engraved with countless ghost runes, which were flickering at this time.

As the machine operated, the ghost runes emitted bursts of cyan lightning, hitting the zombie eggs one by one, as if to stimulate the eggs to hatch.

As far as the eye can see, there are at least tens of thousands of eggs here.

And around the entrance of the Yongdao, countless zombies are climbing towards the entrance of the Yongdao.

Xia Lu hurriedly blocked the Yongdaokou with a spatial barrier to prevent other zombies from entering, and at the same time overlooked the entire circular space, frowning.

There is no doubt that the corpse owner is transforming the operation of the Suppression Tower.

In other words, the energy fluctuation that attracted Qi Qi was caused by this group of corpse masters.

However, looking closely at these hyperplastic tissues, Xia Lu couldn't help but wonder.

According to what Han Xiao said, the corpse master can theoretically study the formation, but he can't change it.

Their own mutations do not produce useless hyperbiotes, and there are no genes in their genes that can grow them.

How do they grow these growths?

Any variant is the result of genetic optimization, for example, any animal is very different.

Man can use tools to achieve the possibility of surpassing animals in strength, but it is impossible to achieve this effect on his own.

The mutation of the corpse owners determines that they can only optimize and improve their own genes on the basis of their own genes, but cannot modify their genes and grow tissues and organs that are not used to them in the first place.

So far, the only person he knows who can change genes at will and create new mutants is Han Xiao in his arms.

For a while, countless doubts and doubts filled his heart, directing his gaze to the woman in his arms.

Han Xiao seemed to realize that he was suspicious, and his face stiffened.

However, she seems to have anticipated this for a long time, and there is no superfluous explanation.

"I know what you suspect, you're not calm enough now, it's useless for me to tell you more, you just need to know that I've never cooperated with the corpse master."

Xia Lu raised his eyebrows.

"Oh? Are you saying that the Corpse Master Council accidentally obtained the Alienation Organizations you cultivated, accidentally learned to use them to transform the Suppression Tower, and accidentally used them to raise a large group of zombies? ”

Xia Lu said coldly.

Han Xiao's face stiffened again, lowered his head, and snorted and spit out four words: "It's not an accident!" ”

"That's premeditated!"

Xia Lu sneered.

After receiving the other party's affirmative reply, he already had murderous intent towards Han Xiao in his heart.

If you think about it carefully, the zombie army raided the Beicheng base some time ago, and it was probably due to this woman's handiwork.

The hatching of tens of millions of zombies requires a lot of energy and time, and the only one who can do this in a short period of time is this suppressive gluttonous suppression tower.
