Tianlan returned to her home with the hedron in the monster's head.

As soon as he arrived at home, he felt that his home was still too weak.

Level 3 zombies have evolved the ability to fly, but there is no air defense field in the sky above their own home, so it is necessary to strengthen it.

Tianlan, who was thinking like this, noticed the spar in her hand.

Since the hedron contains a huge amount of energy, why not use it to make a weapon?

Thinking of Tianlan here, he immediately started to make it.

As for how to activate the ability in the spar, this is very simple, as long as someone is next to the spar, the ability in the spar will be activated.

So how to gather the power of the hedron and use it as a weapon is not a problem.

The main thing is how to use the spar to create an automatic protection system, which is a big problem.

As a student of the Department of Mechanics, and in the past three years of continuous learning and growth, Tianlan can more or less make some machinery alone.

How to use the spar in his hand, he basically has a general direction of thinking, and the rest is left to act.

There are still a lot of things waiting for Tianlan to do.

Tianlan flattered everything and paid attention, before he was absolutely sure, he would not rush forward without a brain, even if he had superpowers and the assistance of the system, he would not be like this.

I am not the chosen one, and I don't have so many hole cards, so I have to be careful everywhere.

Lewd development, try not to wave.

In this way, Tianlan once again immersed herself in experiments, using hedron to develop various weapons.

As for the tasks issued by the system, he is saying that he is sure that he will not take that risk without that certainty.

However, Tian Lan, who was immersed in experimental development, did not know that great changes were taking place outside at this time.

The five people who had been injected with the blood essence of the zombies before, two were killed by Tianlan, and three were killing at this time.

Ordinary zombies are not opponents who have become third-level existences at all, and zombies have no hostility towards this kind of monster, even if their companions around them are killed, they will not do anything, at most they will go to get a piece of the pie and eat away at the corpses of their companions.

Strange to say, even if some zombie companions devoured themselves, he would not resist and let the other party eat his body.

Tianlan has also done research on this, even if zombies don't kill each other, but the dead are different.

And the vast majority of those zombies who take the initiative to devour their companions will evolve into second-level zombies.

The current situation is that the third-level ones are devouring the second-level ones, and the second-level ones are still not resisting.

This is probably the class suppression between zombies, and the low-level ones are not allowed to do anything to the high-level.

However, at this time, those monsters may be third-level zombies, but they are not complete, and they still have to make themselves exist by devouring their heads.

Gradually, the surrounding second-level zombies had been basically wiped out, and they shifted their attention to the nearby shelter.

And at this time, the human beings in the shelter are not so comfortable.

The zombies suddenly evolved in an all-round way, originally all first-level zombies, and the second-level ones were very rare, and among a hundred zombies, there was only one second-level zombie.

It's different now, all the first-level zombies have evolved into second-level zombies.

The quality of all zombies has been significantly improved.

The zombies move extremely fast, their strength becomes stronger, and their defense is amazing.

Although it can still be solved with a single headshot, it is not so good for headshots now.

The mobility of second-level zombies is not in vain, although human superpowers can be killed alone.

But the danger is too great, and it is easy to be counter-killed, so usually, two or three superpowers take action at the same time to deal with the second-level zombies.

Fortunately, the number of second-level zombies is not large, and guns can also play a role.

But now it's different, there are second-level zombies everywhere, and ordinary pistols can't do anything at all, unless one shot hits the vital point.

Some second-level zombie attribute special attacks, which specifically strengthen their speed, are more difficult to deal with.

Now almost all of their shelters are facing the siege of second-level zombies, the attack is very fierce, and the ordinary walls can't resist it at all, and they will soon collapse.

The human side is miserable, and sends a plea for help to the alliance through the Internet, but there is no response, and it can only face this crisis alone.

Hundreds of zombies surrounded his shelter, fearless in the face of machine-gun fire, and rushed forward on the corpses of their companions.

From a distance, the scene looks like the cafeteria is open, but it is also the same, for the zombies, it is the opening of the meal.

And for human beings, it is simply a catastrophe, no matter how you kill, you can't kill it all.

The leader finally couldn't sit still, sent all the superpowers, and sent a cry for help to the wandering superpowers in the outside world.

Such things happen everywhere, and for a time the whole world is lively, and everywhere is in full swing.

A shelter not far from the shelter where Tian Lan was before was also under attack at this time.

Compared to them, it's easier here.

The front is also resisting the second-level zombies, but there are people in the back helping them destroy the zombies.

As for the person who helped them, it was the monster created by Tianlan.

No zombie has any ability to resist, it's basically a small zombie, very simple, very fast.

In a short time, the number of zombies was reduced by more than half.

However, seeing such a result, the leader here did not feel excited, but gradually became bitter.

Because those strange-looking monsters have started to attack them.

No machine-gun fire did anything, and every bullet did indeed enter their bodies.

But with little effect, and in a short time, the wound from the bullet healed.

Seeing this, the leader did not hesitate, and asked everyone to replace the machine guns in their hands, it was time for a weapon of mass destruction.

RPG！

With a bang in the RPG, half of the monster's body is gone.

While they were rejoicing about it, a terrifying scene happened.

I saw that the monster's body was regenerating at a speed visible to the naked eye, first the bones, then the internal organs and muscles, and finally the skin.

In less than a minute, the monster was back to its original state, as if it had never been injured.

Seeing such a result, the leader frowned, commanded his men again, and continued to bombard the monster with RPGs.

The monster that had already eaten damage once, this time it did not hard-connect, but dodged the oncoming rocket launcher at a very fast speed.

The damage of RPG is indeed high, but in front of the monster, it seems a little chicken, and it is very easy to dodge the shells.

The monster quickly dodged the oncoming rocket launchers and quickly approached the humans.

After a shot of the RPG, before they had time to reload new shells, the monster was already in front of them.

Looking at the bloody mouth that could swallow the entire head, the entire brain was occupied by fear in an instant, and any action of fear could not be made.

At this moment, a bright red light flashed, and the monster froze in mid-air, and its head slowly fell to the ground.

The leader immediately pulled his men back and ordered them to retreat.

The first wall has been lost, and it is necessary to hurry back behind the second wall and regain its strength.

After doing all this, the leader looked at the figure wrapped in red light in the distance, saluted, and left.

It was none other than Yu Ling, who had told Tianlan the mystery of the spar three years ago.

During these three years, she has been wandering to this day, without joining any shelter.

But its great strength is known to everyone, and it is known as the crimson feather spirit.

At this time, she completely changed her appearance, and her original black and bright hair had turned into a bright fiery red.

The whole body was wrapped in bright red light, and the intense heat distorted the air around it, like a little human sun.

However, at this time, she is not as calm as she seems.

Because the monster who had just been beheaded by her was still moving, and it was clear that the head had been cut off, and it was not even dead, which was completely beyond her cognition.

No matter how powerful a creature is, if its head is destroyed, it will die.

But this monster is different, not only does it not die, but it is still groping for its own head.

Finally, under the continuous groping, he picked up his head and returned to its original state again.

The people in the shelter were stunned and couldn't believe it.

Is this really still a zombie? Why can I still pick it up if I lose my head?

Although Yu Ling didn't know the principle, she still knew one thing very well. If you let these monsters go around hunting, it will definitely be a disaster, and it must be dealt with here.

Thinking like this, Yu Ling no longer had any hesitation, and immediately condensed the red light in his hand.

At this time, the monster also felt threatened, spread its meat wings behind its back, flew into the air, and began to condense its superpowers.

A green light also condensed in the monster's mouth.

Seeing that the condensation was almost complete, both sides released their abilities at the same time.

The two rays of light collided together, and the green light directly canceled out the rays of the feather spirit, and the speed shot towards the feather spirit without slowing down.

At a glance, it can be seen that Yu Ling's superpowers are inferior to this monster.

The feather spirit who dodged the ray was depressed, what kind of monster is this, even if the recovery power is strong, it can fly, and the most unacceptable thing is that it will shoot lasers.

And this laser is even more powerful than the superpower ray that he has condensed, which makes people play.

Although I am very depressed in my heart, I still have to face it, otherwise, the human shelter behind me will be destroyed.

This is simply not a monster that ordinary superpowers can deal with.

The resilience is too strong, you have to find a flaw, and you have to kill with one hit.
