Behind Gate 6 was Gate 7, and Charles found it quickly. If Tuba is right, then 319 should be in it.

"Huh~" Charles's black blade slashed through the wall with trembling force, and to his surprise, such a sharp blade actually only left a gap on it, and the defense here was stronger than he imagined.

When he broke through Laboratory No. 3, it was made of explosives, but he guessed that if he still took the same explosives and put them here, it probably wouldn't work for the house.

Charles could feel that his oxygen was being depleted, and he had to find a way before it was depleted, or the mission would be a complete failure.

"Bump!!" Charles fired a shot from the muzzle of the gun to the lock of the door, and since the knife would not work, he would try the gun.

Seeing the white bone bullet trapped in the metal gate, he was overjoyed and kept pulling the trigger at the doorway.

Just as Charles was about to break the door, a cloud of red blood shot straight into his eyes from behind.

He quickly turned his head. A large piece of the shark on the right side of his body had been bitten off by a black mass.

It was a monstrous beast face floating in pitch-black water, it had no body, its scarlet eyes surrounded by a hazy black mist, and its yellowed fangs were all it was.

Charles quickly turned, raising his gun and shooting directly at the thing.

I don't know if it's because of the underwater reason, or if it's the special body of this thing, the bullet passed through its mouth and didn't hurt this thing in the slightest.

Although the attack did not work, Charles succeeded in drawing the opponent's attention to himself.

The thing shook the black mist off its body and rushed towards Charles with its hideous fangs.

The situation was very unfavorable for Charles at this time, and perhaps he was not worthy of this strange thing on shore.

But under this extremely strong water pressure, he didn't dare to fight with this thing at all, as long as a small hole was cut in the leather diving suit on his body, then he would be in big trouble.

Charles hurriedly swung his feet, brought up the billowing bubbles, and dodged upwards.

Fortunately, Charles didn't come alone this time, just as he was dodging the other party's attack, the sharks around him rushed up, opened their bloody mouths with three layers of sharp teeth and frantically bitten at the thing.

However, this thing does not seem to be afraid of how to physically attack, and all kinds of things that are torn off its body will quickly return to the black mist and condense again.

As long as the sharks slow down a little, the sharp teeth will leave marks on them.

Charles looked at the black mist as if he thought of something, and he took out a mirror box directly from his back, since it was black, then try white.

The dazzling light shone on everything in an instant, and Charles guessed right.

When the sunlight was gone, the mass was gone, leaving only a few scattered teeth floating around in the water.

"It's ...... Relic?" Charles looked at the teeth, and a question popped into his head.

It turns out that it is possible to drop relics if something in the water is killed?

Seeing Feuerbach picking up one with some curiosity, Charles didn't dare to delay, took out the black blade and turned around and began to pry No. 7 continuously.

After a lot of effort, the door finally opened, and the sea water rushed in, filling it to the brim. But the view inside the door surprised Charles and Feuerbach.

The printer-like 319 in Tuba's mouth was not inside, behind the door was a small room that looked like only 5 square meters, and on the wall directly opposite them, there was also a door open.

It was an ordinary wooden door, and at the top of that door shone a faint red light.

"Captain, target, door, back?" said Feuerbach, gesturing quickly at Charles.

Charles behind the leather coat frowned slightly, Tuba didn't say that he had to reopen the door, could it be that 319 needed extra protection for special reasons?

Feuerbach glanced at Charles, who was stunned, and swam into the room.

However, just as he was about to go inside, Char suddenly grabbed him.

Without waiting for Feuerbach to ask, he saw his captain pointing to the open door next to him, and at some point, the huge No. 7 on the door had become No. 3.

A chill rushed to the back of Feuerbach's head, and he turned his head and looked horrified at the door in the wall, it was not a door, it was a relic behind the containment of Door 3, which had bewitched them and made them open Door 3.

"Damn, when the hell did you get scammed by it!" the ugly Charles slammed the door shut.

Feuerbach next to him was terrified, if he had just gone over and opened the door, what would happen to them?

He didn't know, but it was definitely not going to be a good thing.

"Wow~" The icy sea water was pushed away by Charles, and he walked towards the third door to the left of Gate 3.

But just when he thought he would see Gate 7. only to find that the door No. 8 appeared in front of him.

"That door is still working?" said Charles, looking at the messy iron door in the distance.

Gate 3 was motionless, that is, there were no monsters or any really terrifying scenes. But that's it, Charles felt that the thing was even more weird.

Maybe it's not the anomaly caused by Gate 3, it doesn't seem to move, as long as you are vigilant and don't fall into its trap.

Charles quickly thought about it and pointed to the distant depths next to him, Feuerba nodded tacitly, and immediately sent a shark to rush over.

Soon the shark returned, this time swinging its fins beside Feuerbach, as if to signify something.

Feuerbach understood what the shark meant, nodded at the shark, and finally touched its white belly with his hand.

Charles immediately asked Feuerba what was there.

But at this time, the green-haired young man's face was a little hesitant, his hands waved randomly, it was not a flag language but more like body language, fiddling for a long time but never expressing the specific meaning.

Flag language can only mean simple words, and even complex things are not easy to express.

In the end, Feuerbach didn't bother to talk nonsense, pointing into the distance while pushing Charles forward.

As he made his way down the tunnel, Charles quickly understood why Feuerbach couldn't express it.

As they go deeper, they slowly rise up in front of them to form a slope.

As soon as he entered the water of the slope, he could feel the pressure in the water around him rapidly decreasing, and at the end of the slope there was a white line that twisted with the waves, which was the surface of the water.
