After knowing from Dr. Ho that it was the end of the world, both Xingyu and Mia felt that their mindsets had changed. In the past, I still had the mentality of being rescued by luck, but now I know that it is impossible. In the future, the sea will be their home, so they should seriously plan for their future.

After discussing with the two, they agreed that the biggest concern for surviving at sea is vitamin C. This is the most difficult vitamin in the sea to obtain. Now the tomato tree and pepper tree are their main source of vitamins. Now they are planting on the platform of a drifting ship, which is actually dangerous. The weather at sea is changeable, and a storm is enough to leave them with nothing. So be sure to improve the planting method and find a place where it can be planted safely. But in the sea, how can there be no wind and no waves? Heung-woo quickly thinks of the drifting boat left behind by the old man and Xijia. Since meeting the old man and Xijia, they have kept their promise and never boarded the lifeboat. So they don't know what's going on in the lifeboats either.

Xingyu and Mia walked into the lifeboat and saw that it was clean and tidy. Inside, there are six Styrofoam incubators, which are simple Styrofoam boxes for fishermen. Next to the Styrofoam box, there are five 20-litre oil drums. They had already known from the old man's mouth that the old man and Xijia lived on the water in these oil barrels. Heung-woo walked over and shook the bucket and found that all 5 buckets were filled with water. Then Xingyu saw a folded canvas next to the bucket. Xingyu guessed that the old man was like them, using a canvas to catch the rain and putting it in a bucket. In the lifeboat, in addition to the Styrofoam box and bucket, only the old man's fishing rod and a double-barreled shotgun were seen. The two couldn't figure out why there were shotguns in the lifeboats. It's a pity that I forgot to ask Xijia before.

Then, Xingyu and Miya open the Styrofoam box one by one to see what the Styrofoam box contains. Six Styrofoam boxes, three stacked in a row in two. The Styrofoam boxes on the upper floor are all empty, and the two Styrofoam boxes on the left and right on the lower floor are also empty. Only the Styrofoam box in the middle of the lower level contained the contents. Xingyu smiled bitterly in his heart, understanding that this was the old man guarding against them. But looking back, this is also human nature.

When the two opened the only Styrofoam box containing things, they were surprised to see that there were fishing nets inside. Fishing nets are faster than fishing, but before they had only seen old men fishing. It seems that this is also the vigilance of the old man, who dare not use good things in front of them. In addition to the fishing nets, there is only a knife.

Xingyu took out the fishing net and studied. Miya saw Xingyu staring at the fishing net in his hand, and asked curiously, "Do you know how to fish?" Xingyu replied with a wry smile on his face: "I haven't even touched a fishing net, let alone fishing." Xingyu continued: "But I have never eaten pork, and I have seen pigs walk." I've never fished, but I've seen how to fish in movies and on TV! Xingyu began to say to Miyakop: "There are no more than four ways to fish. Casting nets, pulling nets, trawling nets and releasing nets. The nets cast are cast like umbrellas to the surface of the sea to catch fish. The nets that are pulled are like sharp-tailed bags and are pulled by boats. Trawling is the most common method used by fishermen, with two boats towing a rectangular net. And the easiest way to put a net is a rectangular fishing net. A row of floats is tied to the top of the net, lined up in the sea, allowing the fish to crash into it on their own. After Xingyu finished popularizing science, Miya glanced at Xingyu and said, "Ask if you know how to fish." You talk about popular science at length, I really haven't watched TV and movies! I also know it's a fishing net! ”

Mia was right, this was indeed a fishing net with a cast net. Usually small boats use this method of casting nets that can be caught by one person. This kind of fishing net is surrounded by lead blocks. When the nets are cast, the lead falls apart and falls in an umbrella shape. Therefore, it is necessary to cast the net with skill, otherwise the net will not be opened. Xingyu was on the inflatable boat, tried many times, and the fishing nets fell like a shot put. Seeing Xingyu's embarrassment, Miya couldn't help but laugh and lie on the boat.

Xingyu roared angrily: "You think it's easy!" You try it. I saw Miya happily take the fishing net from Xingyu's hand. Mia poses and throws it, and the net falls in perfect umbrella shape. Xingyu stared at the sinking fishing net in amazement, almost unable to believe his eyes. "You're pretending to be a pig and eating a tiger!" Xingyu complained dissatisfiedly. Miya looked at Xingyu proudly and said, "I asked you if you could fish!" Xingyu asked curiously: "Why do you cast a net?" I remember you saying that you have always lived in the city! Mia explained, "Hey, hey! I studied biology. In addition to fishing, you can also catch animals. But we're using mosquito nets, not fishing nets. But the way to cast the net is the same. Xingyu said teasingly: "Since you are a god of netting, then the task of fishing will be handed over to you." When Mia heard this, she glared at Xingyu angrily. The frightened Xingyu ran to Miya's side and cast a net from Miya.

Mia demonstrated and explained: "There are two ways to cast a net. Let's teach you the first method, open the mouth of the fishing net and harvest one. Hold the middle of the harvest net with both hands apart. The ring finger and tail finger of both hands clasp the edge of the net on the same side. Then he threw it out, and then the index and middle fingers of both hands also clasped the rim of the net with the ring and tail fingers. When the net is opened, let it go. Usually small nets will cast their nets in this way. After Miya closed the net, she continued to teach Xingyu the second method: "The second method." Divide the mouth of the net into three ties, the first tie is hung on the outward shoulder, and the second and third ties are grasped in order with both hands. Then turn around and throw out the fishing nets that you are holding with both hands as far apart as possible. In this way, the second and third pieces of lead will open the net, and when the first net slides out of the shoulder, it will be in an umbrella shape. Large-scale fishing nets are usually cast in this way. After Mia cast the net, she felt a vibration in her hand. Mia was stunned for a moment, and then shouted happily: "The net has caught the fish." Xingyu helped Mia and carefully pulled the net onto the inflatable boat. The two saw four fish jumping in the net. Xingyu roared excitedly: "Haha! Sure enough, casting a net is more efficient than fishing. The fish we caught twice in the net was enough for us to eat for a day. Mia dispensed a fish on the spot and cut it into fillets for snack. The two of them were excited to enjoy the fruits of their first fishing.

In the afternoon, Xingyu continued to learn to cast a net. Xingyu, who mastered the essentials of casting nets, quickly mastered these two methods of casting nets. And in the middle of learning to cast nets, you will also catch fish. In the evening, when the two returned to the drifting boat for dinner, Xingyu remembered that they wanted to see if the lifeboat was suitable for planting this morning. As a result, after discovering the fishing net, the two cast the net happily. I forgot about it.
