"Huh? I spent half a day and only got to 40% progress. This is a truly hopeless upgrade," Li Changge said with a crestfallen face.

Li Changge glanced at the mission's time.

Hmm, there are still eighteen hours left.

"Forget it, I'll go to sleep after dinner. I can't take it anymore. I'll get up early tomorrow to do it. I'm so tired," Li Changge said weakly.

He quickly finished his work, got everything done, and then went to sleep.

As for the two strange beasts, he didn't plan to bother with them, since they couldn't go anywhere anyway.

………

The next morning, Li Changge got up and started working before the sun had risen.

After a night of exhaustion, he didn't have much time left.

Li Changge silently repaired, reinforced, and expanded the bottom, front, and middle sections of the raft.

"Task completion progress: 60%"

"Task completion progress: 80%"

"Task completion progress: 90%"

As Li Changge's work progressed, the completion rate of his tasks increased, until...

"Smack!"

After Li Changge repaired and reinforced the last damaged section, the system sent him a message that surprised and delighted him.

"Mission completion progress: 100%!"

"Ding! Congratulations on completing the mission. You will receive the mission reward after the raft is successfully upgraded."

As soon as the system's voice finished speaking, Li Changge's raft suddenly emitted a bright light, so intense that neither of the two strange beasts could open their eyes.

Li Changge quickly closed her eyes, feeling a ticklish sensation in her heart.

In fact, he really wanted to witness the raft's upgrade process, but the bright light made it impossible for him to open his eyes, which was very uncomfortable.

The bright light lasted only about three minutes before gradually disappearing.

Li Changge quickly opened his eyes, eager to see what the upgraded raft would look like.

"Wow, is this a three-masted sailing ship? I love it."

The simple wooden raft had long since disappeared, replaced by a small, all-white boat.

The small boat has three masts erected in the middle section, allowing it to sail in winds up to 65 degrees. The front section has a considerable area, enough to hold a large amount of daily necessities.

Three-masted sailing ships can travel at very high speeds, and as long as the sails on the masts are unfurled, one can experience the joy of sailing at sea.

"Wuhu, is this a three-masted sailing ship? I love it."

Li Changge walked into the driver's seat, facing the sea, and revealed an excited smile.

"Ding, the raft upgrade is complete. The host will receive the mission reward: explosion-proof glass."

A flash of white light, and three thick panes of glass appeared beneath Li Changge's feet.

Li Changge jumped up and trampled on the glass repeatedly, only to find that there wasn't a single mark on it.

"A product of the system, truly excellent, not bad." Li Changge nodded in agreement.

Li Changge then installed the three pieces of glass on the left, right, and front sides of the driver's cab.

By noon, Li Changge had finished arranging everything on the small boat.

"Not bad, not bad, finally a place to shelter from the wind and rain."

Li Changge sat on the deck, suddenly overwhelmed with emotion.

Thinking about the various life-and-death trials he had experienced this week, he felt a chill run down his spine.

"Thankfully, we've all made it through, and things will get better in the future."

Li Changge raised the wooden cup in his hand, touched it to the air, and then drank it all in one gulp.

"The easy time is over, it's time to get back to work."

Li Changge rested for only a few minutes before standing up, finding a thick hemp rope in the cabin, tying one end around his waist and the other end tightly to a corner of the boat.

"You two keep an eye on this rope and don't let it come loose, or I'll die, understand?" Li Changge said sternly.

The two strange beasts rarely saw their master so serious, so they naturally dared not be careless and nodded hurriedly.

After giving a few more instructions, Li Changge looked into the sea, leaped into the water, and swam into the depths of the ocean under the watchful eyes of the two strange beasts.

After gaining affinity with the water element, Li Changge wanted to go underwater to explore the resources in the sea, but he just didn't have the time.

Now that he finally had some free time, he jumped into the sea without thinking.

Diving into the deep sea, Li Changge saw a landscape different from that on the ocean surface.

There are all kinds of marine life on the seabed, such as tuna, sharks, and jellyfish, which constantly pass by him.

The entire deep sea was like a blue sky, and Li Changge fell in love with the environment at first glance.

Soon, as the rope was nearing its length limit, Li Changge finally reached the land on the ocean.

Strictly speaking, this is just a coral reef in shallow waters.

Li Changge took out his toolbox, pulled out a hammer, and started hammering at a small patch of coral reef in front of him.

Clang, clang, clang.

Li Changge exerted even more force, and sparks even flew from the surface of the coral reef.

bite!

A piercing sound rang out, and the coral reef, unable to withstand the pressure, began to crack open from the middle.

Aquamarine Ore: A primary material for forging heavy weapons

"really."

Li Changge's eyes lit up, and he pocketed the palm-sized blue ore.

Li Changge's ambition was not merely to build a small boat, but to create an unprecedented weapon ark.

After collecting the ore, Li Changge swam to the right.

Not far after swimming, Li Changge discovered another ore blank.

Clang, clang, clang.

Li Changge quickly stepped forward, smashed the coral reef again, and took out a dark ore from inside.

Obsidian: A primary material for manufacturing small arms.

Within just ten minutes, Li Changge had found two main pieces of ore, which made him very excited.

With the added benefit of its affinity for water, Li Changge doesn't even need to worry about not being able to breathe in the sea.

This greatly improved his work efficiency.

Over the next half hour, he ransacked the entire coral reef area.

[Obtain 10 Glass]

Obtain 100 seaweed

Obtain 5 Coral Reefs

After scavenging along the way, Li Changge had acquired quite a lot, but unfortunately, he could no longer find any more ore.

"Two ores at the start, and not a single one in half an hour, this is really unlucky," Li Changge muttered to himself, his heart filled with resentment.

After searching for ten minutes and confirming that there were no more resources left, Li Changge reluctantly swam out to sea.

As he swam upstream, another group of sharks lingered nearby, their eyes filled with hostility as they looked at Li Changge.

The shark's gaze sent chills down Li Changge's spine.

Li Changge admitted that he was very good at fighting underwater, but that was only in one-on-one situations.

If a team of sharks has at least three or four, then there's really nothing we can do.

Knowing when to stop, Li Changge accelerated upstream again to avoid any unnecessary accidents.

The sharks were hesitant at first, but just as they were about to make their move, they found that their target had disappeared, so they had no choice but to give up.

Wow, that's some speed...

Absolutely top-notch...
