Chapter 15： Evolution Tail Spike

"Rats are gregarious animals, can't there be just one mutant mouse? And I just saw more than one."

Just when Luo Fan killed the mouse, he heard movement again.

"really!"

There was another movement not far away, and Luo Fan hurriedly retracted his body into the foam box.

Immediately afterwards, a second mouse appeared.

The mouse also got up and stuck its head into the foam box.

The foam box is full of rotten meat, but at this time, these rotten meat are like mashed meat, and they are still agitated mashed meat, bulging.

On the top of the rotten flesh, there was the corpse of a huge rat.

Apparently, the mouse noticed its dead companion.

Perhaps because it is an extraordinary creature, this mouse has a certain wisdom, at least when it sees the corpse of its companion, it is a little dazed.

He seemed to be thinking about why his companion died here.

And just when it was in a daze, three tail thorns suddenly came out of the muddy flesh and pierced into the mouse's brain in an instant.

The second mouse, died.

Curiosity not only kills the cat, it kills the mouse as well.

Luo Fan's eyeball emerged from the mud, and turned his eyeballs to look at the dead mouse.

"Kill another one, I don't know if there are any more. For the time being, let's absorb them first."

Immediately afterwards, several of Luo Fan's intestines began to eat away the mouse that died first.

The flesh of the mouse was bit by bit eaten clean by Luo Fan.

After a long time, there was no sound.

"Maybe there are only these two mice here."

Rowan thought so:

"After all, I also opened a box of rotten meat here two days ago, and I didn't encounter a mouse after absorbing it for two days. If there were a lot of mice, I would have encountered it long ago, and I wouldn't have seen it today. Maybe it came out because there was not enough food stored in the mouse hole."

The more he thought about it, the more Luo Fan felt that his guess was right.

There shouldn't be many mice here, at most a few more.

Although mice are social animals, there are not too many mice in a mouse hole.

"Absorb first, and try to strengthen the tail thorn."

Luo Fan set a target and strengthened his attack methods.

He had a hunch that in this dust-shrouded city where the fire had just been put out, there must still be some extraordinary creatures that did not die.

That will be a potential danger, and he needs to face it carefully.

Then, part of the energy began to converge on the tail spine, proliferating the cells on the tail spine.

At the same time, Luo Fan also transmitted biological energy to the tail spine.

At the very tip of the tail spine, there is a bone spur, which is the best way to penetrate the enemy's body.

On the one hand, Luo Fan began to evolve some cells on the bone spur at the tip of the tail spine into level 3 cells.

On the other hand, he is still lengthening the length of the bone spur, trying to pierce the enemy with one stab.

Soon, some of the cells in the tail spine evolved into level 3 cells.

【Grade 3 bone spur cells】

Function: sharp, hard, with weak neurotoxin.

"Weak poison, my tail thorn can release poison now."

Luo Fan was overjoyed for a while, so his attack method was even more powerful.

"Level 3 cells are really powerful, but there are still too few level 3 cells to be upgraded, and biological energy is still needed."

Immediately afterwards, Luo Fan stopped being stingy with biological energy, and began to transfer all the biological energy absorbed by his body to the tail thorn, which was to make his attack ability stronger.

On land, in this ruin, an extraordinary creature jumped out at no time.

Therefore, what Luo Fan needs most at the moment is the ability to protect himself.

A large amount of biological energy was extracted from the mouse's body, and then transported into Luo Fan's cells.

Soon, under the collective action of the eight intestinal tracts, a mouse nibbled cleanly.

In the end there was only one white bone left.

"Alright, nearly 1 gram of bioenergy was absorbed."

In the corpse of this mouse, Luo Fan absorbed almost 1 gram of bioenergy.

At that time, he absorbed more than 20 grams from the body of the black fish, but he did not absorb the body of the black fish at that time.

But Luo Fan always felt that the black fish was not an ordinary extraordinary creature. At this time, it was quite satisfactory to absorb 1 gram of biological energy from this mouse.

One gram of bioenergy can evolve one million cells.

Although it looks like a lot, it is not even a single bone spur that has evolved, and it has evolved to a point with a length of one centimeter at most.

However, Luo Fan turned his attention to the second mouse.

Here's another one.

"Continue to evolve."

The biological energy began to be transmitted to the tail spine again. In addition to absorbing the mouse, Luo Fan also accumulated a lot of biological energy on the black fish.

In the same way, he put those accumulated bio-energy to use.

After about half a day, the eight intestines were eating together very fast, and the second mouse was only left with bones.

"The bioenergy of the second mouse was also about 1 gram."

Luo Fan transfers all the bioenergy absorbed to the bone spurs on the tail spines.

With the biological energy of these two mice, and the biological energy extracted from the body of the black fish, Luo Fan finally evolved a bone spur on a tail spine to a length of about three centimeters.

It was a twelve-centimeter-long bone spur, like a straight fishbone.

The ground at the front three centimeters is completely composed of level 3 cells.

But this bone spur is much harder, and the hardness brought by level 3 cells is no less than steel.

In addition to this bone spur, the other two tail spines have not evolved.

Luo Fan gathered all the energy of his body to create this bone spur.

"Now I'm not afraid of confronting the mouse head-on. My bone spurs are enough to kill the mouse with one blow."

Luo Fan is very confident, and this bone spur has become the source of his confidence.

Immediately afterwards, Luo Fan absorbed the rotten flesh in the foam box. He no longer needed these rotten flesh as disguise to kill the enemy.

Maybe it was not needed in the first place, but Luo Fan overestimated the combat power of the mouse and underestimated his own ability.

It took another two days for Luo Fan to completely absorb the rotten meat here.

At this time, Luo Fan had been in this supermarket for five days.

His size has grown again.

The eyeballs got bigger again, and the various organs on the body also got bigger.

The mass also came to 3.2kg.

"There are no more foam boxes with food here. Then I can explore that mouse hole. I need bioenergy to complete my physical evolution."

Luo Fan realized how powerful the Level 3 cells after the evolution of biological energy was, and at this time he was full of desire for this kind of energy.

According to his conjecture, there should be biological energy in that mouse hole.

Immediately afterwards, Luo Fan started to move.

The whole eyeball came out of the empty foam box.

The octopus legs supported Luo Fan's body and let him go to the hole.
