The bottom of the sea is a colorful world, with colorful fish swimming in gorgeous corals, strange underwater creatures and seaweed of various colors floating on the bottom of the sea, forming a beautiful picture.

Mu Xiyan's nerves were tense, and his eyes glanced vigilantly at the unusually good-looking underwater creatures floating around his body.

The more beautiful things are, the more poisonous they are!

There are many varieties of jellyfish, most of which are translucent, pink, or light green or blue. Half-open mouth spit out a bubble, two sesame-sized eyes are in a circle, the body flutters, and the slender tentacles are entangled, stupid, silly, very cute, right?

If it weren't for the bloody paradigm ahead, who would have known that this adorable creature was highly poisonous?

Isn't it cute when it spits bubbles?

What if you were told that once the human body gets into this bubble, it will lose its mobility?

When its glowing tentacles are entangled, do you want to touch its clumsy and silly appearance?

What if you were told that these fragile-looking boneless tentacles could puncture the skin and cause the heart to fail quickly?

Do you still think these things are cute?

Danger lurks all the time!

Mu Xiyan carefully avoided a brightly colored puffer fish beside him, and felt that the water on someone's back was moving, so he turned his head sideways.

A person who is not a stranger, he has had several cooperation on the strategy, called ...... Mu Xiyan thought for a while and couldn't remember his name, but he remembered the code name clearly, 5354.

For this reason, Mu Xiyan nodded slightly to him, which was regarded as a greeting, and then continued to swim forward, who knew that his arm was pulled by the person behind him.

Mu Xiyan unloaded the force in her hand and rolled her eyes angrily, this kind of sneak attack was very dangerous, if she hadn't reacted quickly, this palm would have been split.

"Is there something wrong?" Mu Xiyan turned around and asked in sign language.

5354 smiled shyly, and he slowly stretched out his hand, a colorful gem in his palm.

Mu Xiyan looked at him puzzled, and gave her the gems?

5354 danced with his hands, and then put the gem into her hand while Mu Xiyan was stunned, and swam away as if fleeing.

Belch......

Mu Xiyan stared at the gem in her palm, and then looked at the fleeing figure, was she confessed ......?

Although he felt a little incredible, Mu Xiyan did not forget what a dangerous environment he was in and the heavy responsibilities he was having.

After such a delay, she had already fallen a short distance from the others, Mu Xiyan restrained her excess emotions and swam towards her destination with her limbs open.

On this trip, they were targeting the slippery toothfish.

The slippery tooth fish is generally two meters three in length, with sharp and slender teeth, and can bite adults in two in one bite, which is a very ferocious fish. Even if all the students in the large class kill the slippery fish, if they don't cooperate well, they will all be wiped out, this is a graduation ceremony of blood baptism!

The final battle of the graduation ceremony is not destined to be ordinary!

Brother Ren, who was swimming at the front, stopped swimming and floated on the bottom of the sea, carrying a long-lost telegraph on his wrist.

This communicator has only one function, positioning the tracker.

This was handed over to him by Yan Chenghui in front of all the students this morning.

The red dot on the screen flashes, which means that the slippery tooth fish is nearby.

He made a gesture, and the students stopped. Brother Ren is their leader this time, and they absolutely obey his orders.

The bloody experience of the past has taught them that the more dangerous the task, the more they must cooperate and obey!

Mu Xiyan quietly swam to Jiang Danqiu's side and quickly stuffed something into her hand.

Jiang Danqiu looked down and saw that it was a miniature syringe, only a finger long, and there was a tube of potion in it.

She clenched her fists, hid the syringe, and winked at Mu Xiyan: "What do you mean?"

Mu Xiyan looked directly at the brother in front of him who gave orders, and quietly wrote three words on her arm.

"Anesthetics. ”

Jiang Danqiu's hand holding the syringe tightened, and Xi Yan, who never took shortcuts, actually prepared the anesthetic......

Mu Xiyan smiled bitterly, she also had no choice, the locator in this slippery tooth fish was installed by her last night.

According to the data, the smoothtooth fish is a solitary fish, so Yan Chenghui set it as a graduation task, but things always develop towards the unexpected.

Last night, after she installed the locator, she was almost attacked by another slippery toothfish, if she hadn't been cautious, intuitively dangerous approaching, and feeling the fluctuation of the current, her life would have been confessed here last night.

The smoothtooth fish installed the locator was anesthetized and incapacitated, and Mu Xiyan fought with the sneak attack of the smoothtooth fish for more than ten minutes before she was seriously injured by the smoothtooth fish, of course, she herself was seriously injured and went ashore.

After going ashore, she reported the following situation to Yan Chenghui, and although he was surprised, he still did not change the final result.

The graduation task needs to be approved unanimously by all tutors, and it is not something that can be changed if you want to.

In the end, Mu Xiyan, who had walked half the way, went home again, and asked Yan Chenghui for a half-tube of anesthetic, which was the one in Jiang Danqiu's hand.

"Is it dangerous?" Jiang Danqiu asked in the same way.

Mu Xiyan didn't have time to answer, Brother Ren had already assigned the task, she and Jiang Danqiu became the captains of the team at the same time, and they had to go over to discuss.

Brother Ren's strategy was to become three squad leaders, including him divided into four squads, east, west, north, south, and four sides, and he had to wait until all the people from all four sides arrived before attacking together.

This time, each of their tools is a fighting knife, and the battle time can only be twenty-five minutes, and it must not exceed half an hour, and the smell of blood here will attract other underwater creatures for a long time, and then it will be a bitter battle.

After negotiating, the four of them led their teams to act separately, and before leaving, Mu Xiyan glanced at Jiang Danqiu.

Mu Xiyan was the first team to arrive at the habitat of the slippery fish, and she explored the road last night, and she was not the first to be sorry for the injury she suffered last night.

Among the colorful corals, two brown spotted slippery toothfish were very conspicuous, and Mu Xiyan sighed, although he had long known in his heart that this would be the result, he was still very disappointed. The slippery toothfish that attacked last night really didn't die!

There are many kinds of creatures in the water, I haven't paid special attention to them, and I don't know much about their personalities, Mu Xiyan looked at the five people behind him, they are nothing unusual, I guess I haven't paid attention to it!

The second team to arrive was Brother Ren, who was guided by a locator, a little faster than the other two.

Mu Xiyan saw Brother Ren's changed face and knew that he understood the habits of the slippery toothfish.

The third team to arrive was another student, Mu Xiyan didn't know his name, but he knew his number, the martial arts had been hovering in the top three, and the last one to come was Jiang Danqiu.
