In the deep sea.

Lin Qiye and Amamiya Haruki dived slowly, and the beam of the flashlight passed through the dark sea and landed on the reef at the bottom.

They stayed close to the seabed and searched the surroundings. Lin Qiye stretched his mental power to the extreme, monitoring the surrounding environment at all times like a radar. Finally, he seemed to sense something and made a gesture to Amamiya Haruki.

Amamiya Haruki nodded, followed Lin Qiye, and swam in a certain direction.

After the two swam on the seabed for a long time, the flashlight beam suddenly became deeper, and the underwater reefs beneath them disappeared, replaced by a huge underwater pit with a radius of hundreds of meters.

The outline of the pit is a circle that extends towards the bottom. Standing next to the pit and looking down, the flashlight beam shines into the dark sea water, making it impossible to see the situation at the bottom of the pit clearly.

The two looked at each other, nodded at the same time, and then jumped to the bottom of the pit.

In the endless darkness and sea water, the two people didn't know how long they had been falling. Since entering this pit, the laws of physics seemed to have changed mysteriously. The buoyancy of the sea water did not slow down their falling speed, but made their speed faster and faster.

In the end, Lin Qiye and Amamiya Haruki were unable to control their diving speed, and they didn't even have a way to judge how deep they had sunk.

Time passed by minute by minute, and suddenly the two felt dizzy, and the whole person was ejected from the sea, drawing an arc in the air, and fell heavily to the ground.

Amamiya Haruki frowned, wearing heavy diving equipment, and slowly climbed up from the ground, his eyes scanning the surroundings in confusion through the diving goggles.

The surrounding environment was pitch black, but through the illumination of the flashlight beam, he could basically make out that they were in a low cave, and the place where they had just jumped out of the water was a vast deep pool about thirty meters away.

"call……"

Lin Qiye took off his mask, took a light sniff, and after confirming that there was enough air here, he began to take off his diving equipment.

A moment later, the two men walked to the deep pool and carefully scanned the deep pool surface with flashlights.

"This deep pool is connected to the sea area we came down from?" Amamiya Haruki said with some confusion.

“It should be.” Lin Qiye nodded slightly. “After passing through that strange deep seabed pit, we were thrown directly here... But I always feel that we sank very deep in the pit. This may not be just the seabed anymore, but more like another independent space.”

"My master also said so." Amamiya Haruki sighed, "However, he himself has not figured out what this relic is."

"This is our mission." Lin Qiye looked up at the road on the other side of the cave and said, "Anyway, let's move forward first."

The two of them walked slowly forward along the narrow cave. Amamiya Haruki hung [Rain Beng] around his waist and placed his hand on the hilt, keeping an eye on his surroundings at all times.

Although the Kakuzu sword cannot be used here, if one only draws the sword and uses swordsmanship instead of using the Kakuzu sword's ability, the sword will not be sucked away by the mysterious force. Although this is just a rumor that Amamiya Haruki heard from his master, he has no intention of trying it out.

After all, there is only one [Yubeng], and once the sword is sucked into the depths of the ruins, it will not be easy to get it back.

Fortunately, we didn't encounter any enemies along the way.

"It's almost the end."

The two walked along the cave for a long time. Lin Qiye's spiritual power sensed the changes ahead and he spoke up to remind them.

Amamiya Haruki nodded and was about to say something when Lin Qiye's expression suddenly changed and he stretched out his hand to stop Amamiya Haruki from moving forward!

"Wait! Don't go any further."

Amamiya Haruki raised his foot in the air, then slowly put it back down, and asked in confusion, "What's wrong?"

Lin Qiye did not answer, but walked to one side of the cave corridor, slowly squatted down, and shone the flashlight on the corner of the wall. There was a thumb-sized miniature laser emitting device hidden in the groove, and on the other side of the wall opposite it, there was also such a device.

The two transmitters were small and black in color, making them difficult to detect in the pitch-black cave. If it weren't for Lin Qiye's mental perception, he would have definitely ignored their existence.

Amamiya Haruki squatted down and asked curiously, "What is this?"

"Infrared alarm." Lin Qiye recognized this type of equipment and explained with a frown, "Once someone passes by here, an alarm signal will be sent to the person who set it up."

“Was this placed artificially?”

"Of course, and it won't be left there for too long." Lin Qiye said confidently.

He looked up at the end of the cave not far away, paused, and spoke slowly, "It seems that someone came to the ruins before me, and also has professional anti-tracking knowledge and capabilities..."

"Is it the mysterious man who bought the diving equipment?"

"It's most likely him, and he's quite alert. When we noticed his abnormality, he should have already started to suspect us. This alarm should be prepared to guard against us."

Amamiya Haruki frowned slightly, feeling that something was not right.

In such a dangerous relic, there is a mysterious man who seems to be an enemy but not a friend, and he also possesses extremely strong combat capabilities... This is definitely bad news for him who cannot use the Huojin Sword.

If he hadn't brought Lin Qiye this time, he would have been completely exposed by now.

"So what should we do now?"

"Tear it down without alerting the enemy." Lin Qiye said calmly, "I learned about this in the training camp. Give me two minutes."

Next, Amamiya Haruki watched with his own eyes as Lin Qiye used an ingenious method to dismantle the infrared alarm device. He slowly stood up, looking at the end of the cave not far away, and spoke thoughtfully:

"Since we haven't triggered the alarm, he shouldn't be too alert. Now we are both in the dark...it depends on who reveals himself first."

After disabling the alarm, the two continued to move forward, passing straight through the narrow passage, and stepped on the ground covered with scorch marks and wasteland. The surrounding environment had completely changed.

In the gloomy sky, a hazy light blue glow twisted like the aurora and poured down from the cloud top. One broken high-rise building after another was buried in the wasteland. Some were half submerged, while others were directly turned upside down, sticking into the ground like barbs.

Gravel on the asphalt road, broken glass shards, shattered tables and chairs, dried deep-sea corals...the densely packed debris seemed to have completely escaped gravity and were hovering in the air inexplicably.

This place is like a chaotic and disordered garbage can, filled with fragments of the city and corpses from the deep sea, yet strangely integrated together.

It seems like the remains of human society were washed here by some mysterious force and should have sunk to the bottom of the deep sea.
