Xiaotuanzi knew that as long as he retreated again, the opponent's high-level zombies would come on stage again. More importantly, because of the effect of the last attack, the controller would arrange at least three level 5 zombies for the next attack!

And seeing the current attack form, Xiaotuanzi can be sure that there is not one controller of this zombie wave.

At least two. Because the attack rhythm of the zombie tide is really too tight, the mutual replacement of low-level zombies and high-level zombies cannot be completed by a controller at all.

My current physical condition cannot swallow the crystal core too quickly, but the big cat can.

Swallowing crystal nuclei of the same level does not require a deep sleep compared to swallowing higher-level crystal nuclei, but the absorption time still takes a long time.

At least one crystal core of the same level requires two hours of digestion and absorption.

Do not swallow it again midway, otherwise Tieniu's current situation may occur.

Big Cat's current progress is 27/100, and it still needs 73 crystal cores. If this is counted as time, it will be 146 hours or just over six days.

Xiaotuanzi was calculating quickly in his mind.

Xiaotuanzi’s current goal is to eat the entire zombie wave!

The layout of high-voltage power lines takes ten hours.

It's been two hours now,

But they cannot be expected to complete the work on time.

This thing is really no joke.

If an accident does occur, the electricity will not be divided into friend and foe. The electricity coming out of the power station is about 10kv. It needs to be transformed through several stages before sending out the side voltage equipment, which is definitely not available on site.

So Xiaotuanzi didn't think the other party could complete the work within ten hours.

Before my body becomes as bad as it was at first, I can last about a day. After the power grid is installed, I will have some breathing time, but it is better than nothing.

If it was completed twelve hours ago, then you still have a chance to maintain your physical condition.

The only problem now is how to collect 72 crystal nuclei, because the big cat has already obtained another one just now, and now it needs 72 more.

With the people behind her holding her down, it would be impossible for her to kill into the zombie swarm.

The risk of using booby traps is extremely high, because only when you are truly out of the attack range and on top of the controller will the opponent send out a team of level 5 zombies and level 4 zombies.

This also means exchanging human lives for level 5 crystal nuclei.

The point is, there aren’t that many human lives to exchange for!

Do we have to carry it on ourselves until the power grid is completed?

Time passes little by little.

There was no need for Xiao Tuanzi to make any decision at all. When Xiao Tuanzi looked weaker and weaker, the warriors who were killing the zombies next to him directly and unanimously attacked the battlefield in front of the little Tuanzi in the middle!

"kill!"

They all pushed it forward.

There are really no orders from anyone.

When the first person moved, the rest of them all moved. They were brave and fearless! Fearless!

The entire team seemed to have become one person, and the tacit understanding among them was impressive.

None of the level 1 or 2 zombies can even cross the pond.

Among them, the third-level zombies were also eliminated by them.

But before Xiao Tuanzi could take a breath, four level five zombies and a large group of level four zombies had already rushed in front of Xiao Tuanzi's team.

But at the same time, Xiaotuanzi's pupils suddenly widened, and the energy fluctuated! She knew what this meant!

The big cat and the male tiger dropped the zombies in front of them and pounced on two level five zombies respectively.

But there are still two Level 5s left, and countless Level Cs.

The frequency of Xiaotuanzi's mental power release suddenly increased.

To deal with two fast-moving level 5 zombies, it is impossible to calculate the movement trajectories of thousands of level 4 zombies and attack them accurately. Although their speed is slower than that of level 5 zombies, her body cannot support the huge calculation.

.

At the same time, she cannot use indiscriminate attacks because the people on her side are also within the attack range!

They have a good tacit understanding, but the level gap is really too big! It's so big that the tacit understanding can no longer make up for it.

Death is inevitable.

But at the moment when they rushed up, those people had already anticipated the current situation. So as soon as those high-level zombies appeared, they chewed up the crystal cores that had been prepared in their mouths.

A person with special abilities cannot accomplish "self-exposure" by himself, but it can be accomplished indirectly.

Swallowing the crystal nuclei will decompose quickly after entering the human body. If the human body cannot bear it at the first moment, then the crystal nuclei will release all the energy instantly.

In fact, Xiaotuanzi also used his own mental power to detonate the controller in his previous life, and then the controller's instantaneous ability to explode the crystal core detonated Xiaotuanzi's crystal core, resulting in the complete destruction of the zombie tide.

When some people swallowed the crystal core, it proved that they had no intention of coming back alive.

With a slight sound, flesh and blood turned into powder, and a circle of energy waves with a diameter of two meters was visible to the naked eye.

All level 4 zombies in the energy circle died.

Xiaotuanzi killed all the remaining level 4 zombies.

The next wave was still level 4 zombies, so the team had to retreat to the rear to rest.

A total of 300 people, 10 of whom were sacrificed in this wave, were distributed one after another in a circle around the Xiaotuanzi battlefield. It looked like they were well prepared, and they exchanged the opponent's combat power at the minimum cost.

But Xiaotuanzi was in a very bad mood!

But there is no time for you to feel sentimental on the battlefield!

Four crystal cores are enough for eight hours of use. All the crystal cores are inside Xiaotuanzi's claws. Because there are too many zombies, the male tiger has no time to collect the crystal cores.

After stabilizing the entire battle situation for two hours, Xiaotuanzi felt a breath.

Promoted!

Tieniu is advancing to Class B!

Success!

Xiaotuanzi killed the fourth-level defenders who were like piles of flesh in front of him. The flames of the hurricane burned a layer of the piles of zombie corpses on the ground. However, because there was a steady stream of zombies behind them, the flames were extinguished by them.

The zombie corpses on the battlefield were too thick, and Ren Yiqing's soil spikes and ground sinkers had no effect at all.

Because there are too many zombies buried underground.

Tieniu's aura of promotion did not cause an outbreak of zombies.

On the contrary, it was quite peaceful.

Tieniu's talent was created by Xiaotuanzi, and others had no idea how powerful it was.

Because there is usually no room for him to perform.

What a talent for one person to guard a city!

Tieniu directly joined the battlefield immediately after the breakthrough.

What is rampage, what is invincible defense!

The moment Tieniu joined the battlefield, everyone's pressure was relieved a lot.
Chapter completed!
