The mutation was a very tedious process, but Wu Zhi did not feel too much discomfort. Pen & Fun & Pavilion www.biquge.info

Except for a faint warmth churning in his body and a slight pain in his muscles, everything went smoothly and ended quickly.

"Through the measurement of the potholes, my body has grown by about five or six centimeters on the original basis. The fangs in the mouth are also much denser, and the direction of evolution is really related to the food that has been digested......

Wu Zhi, who swam quickly from the pit, was very satisfied with his physical condition, perhaps inheriting the agile swimming ability of the slender black fish, and now his speed in and out of the sea water was greatly increased compared to before.

In appearance, his physique has not changed much, but his originally strong body has been elongated a little, and the fish's tail has also become slender.

The tail, which is closer to the popular shape, is the main reason why he swims faster.

The skin blended with the scales reveals the characteristic black color of deep-sea fish, like a flexible shell that protects the internal organs and flesh inside.

The bones on the mouth stretched to the sides again, and the sharp teeth on it were all over the place. It is closer to the giant mouth of the shark, and I believe that the bite force should also be enhanced.

Speed, defense, and bite force, as the most basic things of a deep-sea fish, Wu Zhi already has almost everything.

Now he can be said to really have the ability to protect himself!

"It's a nice feeling to be so light."

"Although I digested two slender black fish this time, the overall change was smaller than that of a large fish with a large skull. Could it be that the evolution of my body is not only related to the amount of food eaten, but also affected by the food genes, and the same gene will become ineffective if you eat too much? ”

Wu Zhi swam out of the cracks in the rocks and swam in a spiral between the seawaters, familiarizing himself with the mutated body and discovering problems at the same time.

In terms of physique, the two slender black fish add up to a slightly larger fish than the large skull fish, and the changes in the body of eating two slender black fish are not so much two as one and a half as one.

In other words, when Wu Zhi ate the second slender black fish, the energy that the black fish could provide to his body was reduced by nearly half!

In this direction, if you eat a third slender black fish, the evolution of the body is only a quarter of that of the first.

In fact, if you think about it, there is already such a pattern in the kind of small black fish that you eat at the beginning.

Obviously, Wu Zhi at that time ate dozens of small fish to survive, but the changes in his body were very limited, far less obvious than the big fish in the skull!

"It seems that if you want to become stronger, you have to eat more, but you also have to pick and choose different genes to eat, which is really troublesome......"

Wu Zhi, who was wandering in the seawater, seemed a little distressed, so he had to find all kinds of deep-sea creatures to take a closer look.

The infinite cycle of "eating and digesting, and getting stronger after digestion" that I imagined at the beginning became difficult.

After all, under normal circumstances, it is unlikely that the species living in the same sea area will be so numerous that they will overflow!

"If you want to find different kinds of creatures, you have to constantly move around the deep sea......

"When I think about it this way, the environment of the rock wall is really kind of tailor-made for me."

Wu Zhi let out a heavy sigh.

Based on the available information, the Rock Wall, which is inhabited by a variety of different creatures, is indeed an excellent place to evolve.

But the more this was the case, the more Wu Zhi's instinct told him that it would be very dangerous to stay in the rock wall for a long time!

"Forget it, let's go to the top of the giant wall first and see what we find."

In the end, Wu Zhi shook the fish's head and put away his complicated thoughts.

Looking up the huge rock wall, the black plants covered in it stretched like a pitch-black carpet and disappeared into view.

Instead, there is pure darkness, unpredictable of what will suddenly appear there, full of unknown horrors.

After a slight hesitation, Wu Zhi flapped his strong and powerful tail, flapped his fins, and swam towards the top of the rock giant wall.

When he first came into contact with the Rock Wall, he had already swam some distance. It's just that at that time, he didn't know anything about the rock wall, and his body was not as strong as it is now, so he didn't explore too deeply.

According to Wu Zhi's estimate, the top of the rock wall should not be too high, after all, the top layer of the crater is there, no matter how you say it, it will not be high to the sea.

I have to say that the feeling of swimming in the slender body is extremely pleasant, and the water that has been pushed away is instantly left behind, and the water pressure felt by the head has become much smaller.

The distance that used to take ten minutes to reach, now Wu Zhi may be able to easily reach it in seven minutes!

On the way upstream along the rock wall, from time to time there are familiar skull fish and black fish in the field of vision.

Wu Zhi, who had digested the slender black fish, had stabilized his field of vision at about thirteen meters, which could be regarded as a slight increase.

Of course, I have seen a lot of strange small fish and suspended matter. Perhaps it's because it's far from the dangerous craters in the rocky walls, and there are plenty of small fish, with the occasional smaller school of fish.

It has been maintaining a balanced speed upstream, and after ten minutes, the top of the rock wall has not been seen.

Just as Wu Zhi began to question his guess, cylindrical black shadows appeared on the smooth and steep rock face.

The snake-like body writhing in the shape of an "8" made Wu Zhi stop and look at this new deep-sea creature.

The creatures writhing against the rock wall were not too large, about the size of slender black fish. However, there are no dorsal and pelvic fins that ordinary fish should have, and the tail is slender and has short barbs. The head of the fish is pointy, and it is not possible to see that there are long tusks common in deep-sea fish in the mouth. The eyes are small, but they are a bit like eels.

But unlike eels that live in freshwater, these creatures that appear in the deep sea have faint white spots all over their bodies.

Overall, it shouldn't be too aggressive.

And it was precisely this kind of docile appearance that attracted Wu Zhi's attention, because he found that even if there were relatively large fish such as skull fish around him who saw this creature, they swam away in a daze, without the slightest intention of attacking and predating.

"Is there anything special about this kind of guy, is it poisonous in the body? Or is there a long thorn hidden in the conical mouth? ”

The long swimming time made Wu Zhi feel a little boring, and it just so happened that this group of cylindrical fish writhing their bodies against the huge rock wall was an object to pass the boredom.

So, Wu Zhi slowly swam over to approach the fish, wanting to see what special things existed on them.
