But in the next moment, Xiao Yi suddenly understood the good intentions of the system.

The reward for signing in today may be for this undersea trip.

After realizing this, Xiao Yi no longer hesitated and said, "Don't follow me next, there may be more advanced marine creatures appearing later, the two of you get on the ship first, hold this contract card, always Get ready and use it as soon as you hear my order."

After the two of them heard Xiao Yi's order, they were stunned for a moment, and then immediately responded: "Yes!"

The two soldiers returned to the ship with the contract cards.

Xiao Yi is also a little helpless to do this, because the contract card can only be used on the island tablet.

With the dive, the level of marine creatures gradually changed to SS level, but Xiao Yi had Xuanyuan Sword, and he still had an advantage against these marine creatures.

Those SS-class marine creatures were beheaded one by one.

When he obtained the SSS-level contract card before, Xiao Yi's own level was relatively low, and he could not find SSS-level animals or humans to contract.

Even if they met at that time, Xiao Yi guessed that he was instantly killed by the opponent before he got close to him.

But today is different from the past. With the improvement of medicinal pills, Xiao Yi can even wrestle with SSS-level animals.

Therefore, those SS-class marine creatures can no longer enter Xiao Yi's discernment.

After about five hours of diving, Xiao Yi finally saw the rough seabed.

About five hundred meters in front of him, there is a green stone.

In this dark seabed, the green stone is very conspicuous.

"I found it!" Xiao Yi secretly said.

This kind of stone is the energy spar, and the one that the Spirit Aberdeen gave him last time is this kind of stone.

But Xiao Yi did not rush forward, but looked around vigilantly.

It was very quiet here, and there seemed to be no marine animals, but Xiao Yi felt a tinge of heart palpitations.

He slowly swam forward, getting closer and closer to the energy spar, and suddenly the entire seabed moved slightly, and a huge long black shadow rushed towards Xiao Yi.

The Violent Pill that was originally placed in his mouth, swallowed it instantly, and at the same time stabbed the Xuanyuan Sword in his hand forward.

Pfft!

Xiao Yi felt that he had stabbed the opponent and hurt the opponent.

At this time, the entire seabed was turbulent, Xiao Yi immediately went upstream, and out of the corner of his eye, he saw a huge black shadow chasing him behind him.

"What is this? It was a long strip just now, but now it has become a big piece?" Xiao Yi muttered in his heart.

At this time, the system prompt sounded: "Turtle snake (SSS level): It is formed by the symbiosis of sea snakes on sea turtles. It has strong defense and attack, and it is more dangerous!"

Because Xiao Yi has already swallowed the Violent Pill, for the current Xiao Yi, this turtle snake is just more dangerous.

"Isn't this the image of Xuanwu in the legend?" Xiao Yi thought in shock, but his hands and feet did not stagnate at all, and he went upstream frantically.

There is a strong defense in the system prompt, which should refer to sea turtles, and the sea snake parasitic on it has limited defense.

Xiao Yi's sword should have hurt the sea snake just now.

This also angered Turtle Snake, chasing after Xiao Yi frantically.

How can Xiao Yi's speed be comparable to the turtles and snakes in the water?

Soon, he was caught up by the turtle snake!

"Bang!"

The sound of the crash in the water was unusually dull.

Although the impact was huge, the jumpsuit blocked the direct damage of the impact. Xiao Yi just felt a little uncomfortable from the shock and didn't suffer much damage.

Instead, because of this impact, Xiao Yi floated to the sea more quickly!

The turtle and snake behind saw Xiao Yi going upstream more cheerfully, and he was willing to let him go, and continued to follow.

After chasing and fleeing like this, after chasing and fleeing for a full two hours, Xiao Yi was almost vomited by the back and forth impact, and finally he had seen the light of the picture.

Bang!

This collision directly pulled Xiao Yi out of the water. Xiao Yi, who flew out of the water, saw that the big boat was still quite a distance away from him.

"It seems that the swim is crooked!" Xiao Yi was helpless. After falling back into the water, he frantically wanted to swim to the big boat.

Turtle Snake seemed to see Xiao Yi's purpose and immediately began to block it.

The huge sea snake pulled Xiao Yi in another direction, Xiao Yi was pulled out of the sea again, the resistance in the air was much smaller than that in the sea, this time Xiao Yi flew directly out of forty or fifty meters!

Pfft!

Xiao Yi fell into the sea!

This time Xiao Yi did not continue to escape, but immediately inspired Huicheng Stone!

Seeing the light from the Huicheng Stone, the turtle snake seemed a little curious, and they were not in a hurry to attack the next time.

As a result, it just gave Xiao Yi time to motivate back to the city stone.

Twenty seconds later, Xiao Yi immediately appeared on the big boat. He immediately ran to the deck and shouted to the turtle and snake, "Hey, here!"

Turtle Snake looked back and saw that Xiao Yi appeared on the big boat, and immediately felt that he was being tricked, and swam frantically towards the big boat.

"Use the SSS-level contract card on the turtle and snake!" Xiao Yi immediately used the contract card on the island tablet!

A golden chain wrapped around the turtle snake, but the turtle snake had no resistance.

Soon the contract was completed, and the turtle became Xiao Yi's pet.

"Great!" Xiao Yi was already in a weak state at this time, but he was still excited, "You will be called Xuanwu in the future!"

Turtle snake responded: "Yes, master!"

"As expected, it is an SSS-level contract card. You can successfully contract an SSS-level turtle and snake with your own SS-level level, and there is no mutiny yet!" Xiao Yi secretly said.

At this time, he was in a weak state, and he was not even as good as an S-rank master. The turtle snake was still so respectful, which showed that it was definitely the role of the contract card.

With Xuanwu, it was much more convenient for Xiao Yi to go into the water again. Sitting on the back of the turtle snake, the symbiotic sea snake fixed him, and then quickly swam to the bottom of the sea.

When I came to the spar lode again, Xiao Yi discovered that the lode was very large. I believe that as long as it was mined, there would be no need to worry about the energy spar for a long time!

"Xuanwu, you are here, is this thing useful to you?" Xiao Yi asked curiously.

"Yes, if you want to break through the SSS level, you need a lot of energy!" Xuanwu replied.

Xiao Yi's heart moved, he even mentioned breaking through the SSS level!

"Can you use the energy in this energy spar?" Xiao Yi asked curiously.

"Not currently, there needs to be a specific method." Xuanwu replied.

"Do you know how to do this?"

"Won't!"

Xuanwu's answer was unusually straightforward, making Xiao Yi speechless: "No, you are still guarding this."

"Always prepare for the future!" Xuanwu replied.

Xiao Yi was at a loss for words, Xuanwu thought well, he really needs to prepare for the future!
