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

Submarine spare parts were rare before the apocalypse, let alone after it.

So, even though they knew the sonar system was damaged, they couldn't repair it.

Qi Mingyu pondered for a moment, then turned his gaze to Zhou Shuwan: "Wanwan, how is your injury? Can you still sense your surroundings?"

The others looked at her nervously and expectantly.

Zhou Shuwan smiled and said, "My injury is just a minor skin injury. It won't affect my perception of space."

"Okay, let's rest here for two days and wait for Wanwan to recover. We'll set out again in two days."

If there is no sonar system at that time, we will have to rely entirely on Zhou Shuwan.

As they traveled along, they actually relied on Zhou Shuwan to guide them in the direction of the fish school.

But after all, there is still the sonar system to rely on. Now we can only rely on it, which makes people feel more stressed!

Zhou Shuwan didn't feel any pressure at all and nodded, "Okay, then we'll stay for two more days. We can also use these two days to carefully inspect the submarine."

Qi Mingyu, wearing a diving suit, swiftly crawled out of the submarine's hatch.

The cold sea water instantly enveloped his entire body, and the temperature regulation system in his diving suit immediately activated to resist the coldness of the deep sea.

He held a flashlight in his hand, and the beam of light drew a bright light in the dark deep sea, shining towards the tail of the submarine.

The outline of the propeller gradually became clear under the beam of light, and several tiny cracks and slight deformations came into view.

"Sure enough..." Qi Mingyu frowned slightly.

He carefully inspected the propeller. The deformation was not too big, but it might affect the high-speed operation of the submarine.

He sighed, patted the propeller gently, as if to comfort his old friend, then turned and swam back to the submarine.

Inside the submarine, Zhou Jianghai and Mu Mu were squatting in a corner of the cockpit, holding wrenches and circuit boards in their hands, trying to repair the sonar system.

Mu Mu carefully removed several damaged circuit boards and turned to look at Zhou Jianghai: "Dad, this board must be burned out. We don't have a spare one, so it probably can't be repaired."

Zhou Jianghai frowned, squatted down, carefully examined the circuit board, and shook his head: "There's really no other way. We can only wait until we get back to the island."

Qi Mingyu needs someone to go out with him to help him repair the propeller.

Naturally, Mu Mu was the one who took on this task.

He has only been learning mechanical maintenance from his father for a few years, but he has some experience.

He thought the same as his mother and sister: the seabed is full of dangers, and they didn't want their elderly father to bear that pressure.

The two put on their diving suits and went outside together.

The cold sea water instantly enveloped their entire bodies, and the flashlights shone towards the tail of the submarine.

Under the beam of light, the outline of the propeller gradually became clear, and several tiny cracks and slight deformations came into view.

Mu Mu took out underwater welding tools from the tool bag on the waist of his diving suit and handed them to Qi Mingyu.

Qi Mingyu took the tools, skillfully adjusted the power of the welding gun, then aimed at a crack on the propeller and began to weld carefully.

The sparks from welding emitted a faint glow in the deep sea, illuminating the two men's focused faces.

Mu Mu watched Qi Mingyu's movements closely from the side, handing him tools or adjusting the power of the welding gun from time to time.

The two of them worked together so well that they hardly needed to communicate verbally.

The cracks on the propeller were gradually repaired in Qi Mingyu's hands. Although the welding marks were not very beautiful, it at least ensured that the propeller could work normally on the return journey.

Mu Mu carefully checked the propeller and after confirming that there was no problem, he gave Qi Mingyu a thumbs up to indicate that the repair was complete.

Qi Mingyu nodded, put away the welding tools, then patted Mu Mu on the shoulder, indicating that they could return to the submarine.

The two-day rest period passed quickly and the inspection of the submarine was basically completed.
