Reborn: I Stock Up and Bully the Trash to Dominate the Apocalypse

"How much oxygen is left?" Zhou Jianghai asked in a low voice.

Mu Mu quickly checked: "Less than twenty minutes!"

This number made everyone's heart sink.

Twenty minutes means they must find a safe surface point within this time, otherwise they will suffocate on the cold seabed.

"Wanwan, what did you find in the waterway ahead?" Qi Mingyu asked, his eyes fixed on the dark waters ahead.

Zhou Shuwan closed his eyes again and concentrated his mind. "This waterway winds forward and enters a larger underground cavity after about a hundred meters. There seems to be an upward passage on the other side of the cavity, but..."

"But what?" Zhong Tiyun asked anxiously.

"But that passage is blocked by a lot of rubble, seemingly caused by a recent landslide." Zhou Shuwan opened his eyes, brows furrowed. "However, I can feel water flowing above, which means there's an exit leading outside."

"As long as there's an exit, it'll be fine." Qi Mingyu's eyes flashed with determination, "We can clear the rubble and force our way through."

It’s better than being trapped here to death!

The submarine continued to move forward and soon entered the underground cavity that Zhou Shuwan mentioned.

This is a huge underwater lake, surrounded by towering rock walls, which flicker dimly in the light of the submarine lights.

"It's right there!" Zhou Shuwan pointed to the other side of the lake, where there was a hole blocked by rubble, and water was slowly seeping out from the cracks in the rubble.

Qi Mingyu piloted the submarine closer to the cave entrance and after careful observation said, "It looks like a landslide caused by the recent earthquake. If we can remove the rubble, we can open a passage leading upwards."

If anyone else were here, they would be at a loss.

But they have Zhou Shuwan...

"Okay, let me try." Zhou Shuwan said immediately.

She could use space to try to move some of the rubble out.

The submarine docked at the landslide site. Zhou Shuwan placed his hands on the bulkhead and collected the rubble in the passage into the space as if collecting supplies.

No moving, just collecting, the time and energy spent are minimal.

But she couldn't be too reckless or collect too quickly, causing another landslide in the already unstable passage.

As time passed, oxygen reserves became less and less, and everyone felt like a huge rock was pressing on their hearts.

"There are only ten minutes of oxygen left!" Mu Mu's voice broke the silence with a hint of anxiety.

Zhou Shuwan took a deep breath and quickened the cleaning process.

As more and more rubble was removed, the hole widened and the water flow became more turbulent.

"I can feel the water pressure changing above!" Zhou Shuwan said excitedly, "The exit is not far away!"

Suddenly, the entire underwater lake shook violently, and gravel fell off the rock wall.

"Oh no! The aftermath of the earthquake!" Zhou Jianghai exclaimed.

Zhou Shuwan gritted his teeth and tried his best to clear the last obstacle.

Finally, as a huge rock was moved into the space, the entrance of the cave suddenly became clear, and a strong current of water rushed in from above, pushing the submarine to the side.

"Success!" Mu Mu cheered, but was immediately interrupted by Qi Mingyu's voice.

"Don't be too happy! We have to surface immediately! We only have five minutes of oxygen left!"

Qi Mingyu quickly adjusted the position of the submarine and aimed it at the passage above.

With the roar of the thrusters, the submarine began to rise slowly.

The passage was narrow and winding, and the submarine had to move forward cautiously.

Every turn presented a new obstacle, but fortunately, they encountered no major landslides along the way.

Finally, they emerged from the passage.

This was the first time anyone had seen such a long, narrow and deep underwater passage.

However, before the end of the world, humans had only developed 5% of the ocean, not to mention that even technological means have degraded now.

No one knows how many disasters have occurred in the seabed in the past few years.

Therefore, it is normal that no such channel was found.
