In the early morning, Xingyu and Mia, who were sleeping in the cockpit, heard Xia Xue's cry from the studio downstairs. Xingyu and Mia, who were awakened by the crying voice, looked gloomy after looking at each other. They guessed that the old scholar was no longer good. Before the old scholar could come out of the pain of losing his wife, he encountered the end of the world, and then he was thrown into the sea and drifted. The old man, who is already in his last years, can't stand such a turbulence at all.

Xingyu once again held his breath and walked into the crew's bedroom, and quickly took a clean sheet. Xia Xue wrapped the old man's body with this sheet. After that, Xingyu, Miya, and Xia Xue worked together to release the old man's body to the sea. Xia Xue and Xiaoxi knelt and wept, while Xingyu and Miya silently watched the old man's body drift away with the waves.

Xingyu didn't want Xia Xue and Xiaoxi to be indulging in sadness all the time, so after they rested for a while, Xingyu taught Xia Xue and Xiaoxi to fish with fake bait. Xingyu doesn't care if they can catch a fish or not, he just wants Xia Xue and Xiaoxi to have a sustenance, and they won't be cranky.

When Xingyu and Miya wanted to turn around and walk to the cab, Xiaoxi saw three black dots on the horizon. Xingyu knew at a glance that it was the barge he was looking for. Xingyu excitedly ran to the wheelhouse and drove the engineering ship towards the barge.

After the engineering ship approached one of the barges, Xingyu jumped out of the barge. As soon as Xingyu stood still, he found a thin layer of black sand on the bilge of the barge, and Xingyu guessed that the three barges were originally transporting sand pumped from the bottom of the sea. The sand carries the silt of the seabed, so it looks like black sand.

Although it is only a thin layer of black sand, the area of the barge is equal to four long containers. The amount of black sand in the three barges is also considerable. Xingyu thought to himself: "I boarded the barge before and only cared about searching the lounge. Unexpectedly, the real treasure is at the bottom of the empty ship. Xingyu then worried about whether the black sand could be used for planting. Xingyu remembered that Xia Xue had said that she was a student of the Department of Botany. Xingyu immediately turned around and raised his head and shouted, "Xia Xue, can this kind of sand mixed with silt grow potatoes, peppers or small tomatoes." Xingyu nervously waited for Xia Xue's answer, afraid that Xia Xue's answer was suitable for growing peppers...

Xia Xue replied hesitantly: "You can grow potatoes, but potatoes don't have high requirements for soil." But peppers and cherry tomatoes can't. After listening to Xia Xue's answer, Xingyu breathed a sigh of relief in his heart.

After Xingyu moved the black sand from the three barges to the engineering ship, he began to prepare to change the barge. In the past two days, when Xingyu was driving the boat to find the barge, he had been secretly thinking about how to modify the barge. So Xingyu will be able to start refitting immediately. But before starting work, Xingyu first taught Miya and Xia Xue to operate the boom. The task of operating the boom was left to these two girls.

Xingyu first hoisted the drifting ship onto the deck of the engineering ship. The oil tank is then separated from the base frame, and then the base frame composed of steel pipes is divided into four pieces. Xingyu placed the four underframes in the four corners of the bilge of a barge, and then welded and fixed them. Then Xingyu stacked another barge on top of the four underframes. It is too difficult for a novice driver to get two booms to fit the barge into the other barge accurately. Xingyu frowned, looking like a barge smashing another barge again and again. Xingyu was worried that the barge would be smashed before it could be put in. Thankfully, it was always a success. Xingyu hurriedly climbed into the middle of the two barges and welded the barges above to avoid moving again.

Xingyu stacked two barges like this, mainly to increase the weight of the bottom of the ship. In addition, the barge underneath can be used as a protective layer. The barge above is the real hull. This increases the weight of the bottom of the boat without being afraid of running aground.

Next, Xingyu flipped the third barge over and built it on top of the second barge. Then Xingyu started to weld and seal the two barges. This is a big project, and it took Xingyu three days to weld it. Fortunately, there are enough welding rods in the construction ship. After that, Xingyu painted all the welding points with anti-rust paint. Xingyu, who studied mechanical engineering, knew that after steel welding, the carbon content of steel increased, and it was easy to rust. Therefore, you must do a good job of rust prevention, otherwise you will rot in a few months if you soak it in the sea.

After Xingyu made sure that the anti-rust paint was dry, he began to fill the barge at the bottom with water. Let the protective layer sink into the sea. Xingyu found that the bottom of the ship was indeed heavy, and the waterline almost reached the junction of the second and third barges.

Xingyu looked at the barge on the engineering ship, and the barge had begun to take shape at this time. Mia was surprised and said, "This ship is very similar to Ark One!" It's just a little ark! Xingyu replied with a smile: "All changes are inseparable, the design principle is light at the top and heavy at the bottom, and then the full cover is sealed." The refrigerators and lifeboats we used before were based on this principle. ”

After Xingyu rested, he began to remove the railing of the engineering ship. The railing was then installed on the outer edge of the deck of the small ark as a deck fence.

After that, Xingyu cut out the raised circular passage of the oil tank, which they originally used as the hatch of the drifting ship, completely. Heung-woo made a hole in the front of the deck of the small ark to install the hatch. Then install the ladder. This is the entrance and exit of the little ark. Then Xingyu cut out a pair of two-square-meter double-open hatches on the deck of the engineering ship, and then installed them at the back of the deck of the small ark. The round small hatch is to facilitate people to enter and exit, but the small hatch is inconvenient to carry things, so it is necessary to have a square hatch cover to facilitate the movement of large items.

Then, Mia and Xia Xue were surprised to see Xingyu dismantling the boom. Miya asked Xingyu in surprise: "Do you want to even move the boom?" No, the engine has to be moved over, right? Xingyu replied angrily: "What do you want an engine for?" When an engine runs out of fuel, it's waste. ”

Xingyu installed the boom attached to the turntable slightly forward in the middle of the deck of the small ark. Then use another boom of the engineering ship to straighten the boom on the small ark upwards, and then weld and fix it. At this time, Mia saw that Xingyu was modifying the sailpole. Xingyu then mounted a chain block on the top of the sail pole and prepared to use the chain block to raise the sail.

After this step was completed, Xingyu took the rain covering canvas he had found in the three barges to the deck of the engineering ship, and after drawing the dimensions, he asked Miya and Xia Xue to sew a spinnaker. Six layers of canvas are sewn into a spinnaker, which is also strengthened by net-like rope. It took Mia and Xia Xue two days to complete the spinnaker.

In the past two days, Xingyu has not been idle. Xingyu moved the items in the engineering ship and the drifting ship into the cabin of the small ark. It only took a day for Heungwoo to finish moving his belongings. The next day, Xingyu installed an iron frame on the deck of the small ark to fix the ice bucket, ready to be planted later. Xingyu installed ten ice buckets on the deck, in fact, the black sand collected in the barge can fill at least thirty ice buckets. But they only had sixteen ice buckets. In addition to planting, it is also necessary to store water.
