"Rats live in packs. There can't be just one mutant rat, can there? And I saw more than one just now."
Just when Luo Fan had killed the rat, he heard movement again.
"Indeed!"
Not far away, there was another stirring. Luo Fan quickly retracted his body into the foam box.
Immediately after, a second rat appeared.
The rat also got up and stuck its head into the foam box.
The foam box was filled with rotten meat, but at this moment, the rotten meat was like meat puree. Furthermore, it was like pureed meat which had been stirred and was a bulging mush.
At the top of the rotten meat floated the carcass of a huge rat.
Clearly, this rat had noticed its dead companion.
Perhaps because it was a supernatural creature, this rat had some intelligence. At least, when it saw the carcass of its companion, it was a little stunned.
It seemed to be considering why its companion had died here.
Just as it was in a daze, three spiked tails suddenly sprang out from the meat puree and pierced into the rat's brain in an instant.
The second rat died.
Curiosity would not only kill the cat but the rat too.
Luo Fan's eyeball emerged from the mud and turned to look at the dead rats.
"I've killed another one. I wonder if there's more. I shall not worry about that for now. I'll absorb them first."
Immediately, Luo Fan's few intestines began to devour the rat which had died first.
Bit by bit, the body of the rat was fully ingested by Luo Fan.
After a long while, there was no sound.
"Maybe there were only these two rats here."
Luo Fan thought to himself, "After all, I had opened a box of rotten meat two days ago and had been absorbing it for two days without encountering a single rat. If there were many rats, I would have encountered them a long time ago, and would not have seen them only today. Perhaps they had come out because there was not enough food stored in the rat hole."
The more he thought about it, the more Luo Fan felt that his guess was right.
There should not be many rats here. At most, there would be a few more.
Although rats lived in packs, there would not be many rats in a rat hole.
"I'll absorb them first and try to strengthen the spiked tails."
Luo Fan set his goal to strengthen his means of attack.
He had a hunch that in this city enveloped in ash and which just had a big fire put out, there must still be some supernatural creatures that had not died.
Those would all be potential dangers, and he had to face them cautiously.
Then, a portion of energy started to converge on the spiked tails to increase the cells on the spiked tails.
At the same time, Luo Fan had also transmitted bio-energy to the spiked tails.
At the very tip of the spiked tails, there was a bone spike. That was the best means to pierce the enemy's body.
On the one hand, Luo Fan had started to let some of the cells on the bone spike at the tip of the spiked tails evolve into level-3 cells.
On the other hand, he was also increasing the length of the bone spike so that it could pierce the enemy with one stab.
Soon, some of the cells in the spiked tails had evolved into level-3 cells.
[Level-3 Bone Spike Cells]
[Function: Sharp, hard, and contains weak neurotoxin.]
"It's a weak toxin. My spiked tails can release toxins now."
Luo Fan was overjoyed. This way, his means of attack would be even stronger.
"Level-3 cells are indeed powerful, but currently, too few cells have been upgraded to level-3. I still need bio-energy."
Immediately after, Luo Fan was no longer stingy with his bio-energy. He started to transfer all the absorbed bio-energy in his body to his spiked tails to increase his attacking ability.
On land, there was no telling when a supernatural creature would leap out from the ruins.
Therefore, Luo Fan needed the means to protect himself most right now. Currently, the spiked tails became the organs where his resources were skewed.
A large amount of bio-energy was extracted from the rat's body and delivered into Luo Fan's cells.
Soon, under the collective action of the eight intestines, a rat had been nibbled clean.
In the end, only a skeleton was left.
"It's not bad. I've absorbed almost 1 gram of bio-energy."
From this rat's carcass, Luo Fan had absorbed almost 1 gram of bio-energy.
Previously, he had absorbed more than 20 grams from the black fish, but he did not finish absorbing the black fish's carcass.
However, Luo Fan had a feeling that the black fish was not an ordinary supernatural creature. At this moment, he was rather pleased to have absorbed 1 gram of bio-energy from the rat.
1 gram of bio-energy could evolve a million cells.
Although it looked like a lot, it was not sufficient for a single bone spike to evolve fully. At most, it had evolved a sharp point of a centimeter long.
However, Luo Fan turned his attention to the second rat.
There was another one here.
"Continue to evolve."
The bio-energy started to be transmitted to that spiked tail again. Apart from absorbing that rat, Luo Fan had also accumulated a lot of bio-energy from the black fish.
Similarly, he applied the accumulated bio-energy.
Another half a day had passed, the rate at which the eight intestines were feeding together was very fast, and only bones too were left of the second rat.
"The bio-energy of the second rat is also about 1 gram."
Luo Fan transferred all the absorbed bio-energy to the bone spike on the spiked tail.
With the bio-energy of the two rats, coupled with the bio-energy extracted from the black fish's body, Luo Fan had finally evolved a bone spike on a spiked tail by a length of about three centimeters.
It was a twelve-centimeter long bone spike, like a straight fishbone.
The bottom of the most proximal three-centimeter segment was completely made up of level-3 cells.
However, this bone spike was much harder. The hardness brought about by level-3 cells was no less than steel.
Apart from this bone spike, the other two spike tails had not evolved.
Luo Fan had gathered all the energy in his body to create this bone spike.
"I'm not afraid to fight that rat head-on now. My bone spike is enough to kill that rat in one blow."
Luo Fan was very confident, and this bone spike had become the source of his confidence.
Immediately after, Luo Fan absorbed all the rotten meat in the foam box. He no longer needed the rotten meat to camouflage himself to kill the enemy.
Perhaps he did not need it in the first place. However, Luo Fan had overestimated the combat ability of the rats and looked down on his own ability.
It took another two days to absorb all the rotten meat here.
At this moment, Luo Fan had already been in the supermarket for five days.
His body size increased again.
The eyeball had once again become bigger, so did the various organs in his body.
The mass had come to 3.2 kg.
"There are no more foam boxes with food here. I can go and explore that rat hole next. I need bio-energy to complete the evolution of my body."
Luo Fan had experienced how powerful the level-3 cells evolved with bio-energy were. At this moment, he was filled with desire for such energy.
According to his guess, there should still be bio-energy in that rat hole.
Then, Luo Fan started to move.
The entire eyeball emerged from the empty foam box.
The octopus limbs supported Luo Fan's body and got him to that hole.
