As the net was in hand, dusk soon fell.
Seeing that there were no more tourists in the park, Yang Lin returned to the artificial lake again.
Before long, the mutated seven-gilled eel emerged from the lake once more.
After activating its electric discharge talent, its body shape did not change significantly. The only difference might be that its body color deepened slightly.
However, it was clear that Yang Lin had not found it again to observe changes in its body shape.
As Yang Lin silently uttered the name "Evolutionary Light," a seven-colored light, invisible to ordinary people, shone upon the seven-gilled eel.
At the same time, Yang Lin opened its talent panel.
Under his gaze, the seven-gilled eel's talent panel underwent a slight change.
[Mutation (Gold Talent) is currently activated. The characteristics of this life form will gradually change with environmental shifts.]
Looking at the "Mutation" talent, which had been promoted from a green talent to a gold talent, Yang Lin couldn't quite understand the meaning of the latter sentence.
"Changing with environmental shifts? Is this the effect of the Mutation talent after upgrading?"
At this moment, Yang Lin felt that he understood, yet he also felt that he didn't.
According to his understanding, this talent should be similar to survival of the fittest; if placed on land, it would grow lungs, and if placed in water, it would grow gills.
If that were the case, this talent would indeed be quite monstrous.
"I wonder if it can adapt to seawater?"
Temporarily setting aside these thoughts, Yang Lin quickly found a pre-prepared aquarium and placed the seven-gilled eel inside.
After transferring the seven-gilled eel, he drove his car to the construction site next to the zoo.
Since it was already after working hours, the construction site was deserted.
Before long, Yang Lin dragged the seven-gilled eel to the side of the large hole dug during the day.
After a series of operations, the man and the eel soon appeared in the cave.
Compared to the daytime, the cave seemed unchanged. More precisely, there was no concept of day or night in this cave at all.
By fixing lighting sources in various corners, the previously dark cave was immediately illuminated with a touch of brilliance.
The reason for doing this was not because Yang Lin was afraid, but because he worried about accidentally stepping on and killing some small animals.
If he killed them, it would be quite a mess.
Discovered during the day, extinct by night.
Moreover, he had already decided to preserve this place intact and develop it into a separate cave exhibit in the future.
Of course, before developing the cave exhibit, the most urgent task was to eliminate all unstable factors.
Thinking of this, Yang Lin, pulling his small cart, quickened his pace.
Five minutes later, he appeared by the underground river.
As soon as the flashlight beam shone into the river, a series of ferocious heads immediately surfaced.
Seeing these enthusiastic little fellows, Yang Lin really wanted to take out his new fishing net, but for the sake of caution, he ultimately gave up.
"You'll have your turn soon."
As he spoke, he took out a bag of bloody beef chunks from the small cart behind him.
He casually tossed a beef chunk into the underground river, and the next second, countless knife-toothed viperfish swarmed towards it.
In less than a tenth of a second, this palm-sized piece of beef, which could sell for more than ten yuan outside, was completely devoured.
Seeing this, Yang Lin's scalp tingled, and he quickly tossed another piece towards the farther surface of the river.
After continuously tossing more than ten pieces like this, there were no longer any knife-toothed viperfish in the river in front of him.
Seeing this, Yang Lin quickly opened the aquarium containing the mutated seven-gilled eel.
As the aquarium was opened, the mutated seven-gilled eel slid into the underground river with the flow of water.
When the mutated seven-gilled eel entered the underground river, the knife-toothed viperfish seemed to sense it and immediately turned to swim towards the seven-gilled eel.
Instantly, the surface of the river seemed to boil.
Yang Lin glanced over and saw that the river surface was full of knife-toothed viperfish, tens of thousands of them.
If it were before, he might have turned and fled at a glance, but now, a sinister smile appeared on his face.
"Yongxin! Shock them with electricity!"
As Yang Lin's words reached the mutated seven-gilled eel, Li Yongxin, blue electric sparks began to flash in the river water.
When the electric sparks reached their peak, they immediately spread out into the river channel like a spiderweb.
The previously aggressive swarm of knife-toothed viperfish, upon contact with these electric sparks, flipped over onto their backs.
In less than a minute, the surface of the underground river was covered with a thick layer of stunned knife-toothed viperfish.
This was even when Li Yongxin was not going all out.
According to Yang Lin's estimation, if the mutated seven-gilled eel Li Yongxin unleashed its full current, the voltage should reach over 2000 volts.
Let alone these knife-toothed viperfish, even sharks would be electrocuted into confusion.
Seeing all the knife-toothed viperfish electrocuted, Yang Lin immediately took out his large fishing net.
At the same time, he also took out the snake-skin bag he had prepared.
As his large fishing net went down, net after net, a large number of knife-toothed viperfish were scooped out of the underground river.
Except for a small portion that he put back into the aquarium, most of them were placed into the snake-skin bag.
As for how many would survive, that would depend on their luck.
In any case, he dared not keep such troublemakers.
It took Yang Lin a full half hour to clear all the knife-toothed viperfish from the underground river onto the shore.
To his disbelief, in just this short period, the knife-toothed viperfish that had been stunned and flipped over had already recovered their vitality.
Even those in the snake-skin bag began to twitch.
Startled, Yang Lin quickly picked up another fishing net and smashed them a few times.
Seeing that they had stopped thrashing, he finally breathed a sigh of relief.
"This fishing net is indeed very effective."
While marveling, he said to the mutated seven-gilled eel Li Yongxin in the underground river:
"You stay here for now, and help me check if there are any other stray fish in the underground river."
"I'll take you back next time I come."
With that, Yang Lin headed towards the exit with his haul.
By the time he had transported all the knife-toothed viperfish back to the Xi Hong Zoo, it was unknowingly deep into the night.
As a precaution, he even moved the aquarium containing the knife-toothed viperfish into his room by himself.
This was the best arrangement before he figured out how to deal with these creatures.
Not long after returning to his room, he fell into a deep sleep, exhausted.
As soon as the next morning arrived, he was awakened by a noisy commotion.
