The four-pointed star had been on a lonely voyage at sea for three days, resting during the day and passing south at night, according to the guidance of the stars as the island's mysterious engineer had said. They weren't sure it was the right method, but the charts weren't in their hands, and now they had the only one they could use.

In the past few days, Zhang Xiaohu has observed and found that in the southern sky, there are three bright stars that always point to the south, and as long as he follows them, he will definitely not lose his way. However, there are still doubts about whether they can reach Tianzhu Mountain smoothly.

As for those people in the Chishui tribe, it was handled more smoothly than Zhang Xiaohu expected, and the villagers in the Chishui tribe were all extremely simple people, they didn't listen to Zhang Xiaohu's too many explanations, and only asked three questions: first, how Zhang Xiaohu was going to settle them; second, the future direction of the four-pointed asterisk; Third, did Zhang Xiaohu hurt the goddess.

Zhang Xiaohu answered these three questions sincerely, he didn't intend to hurt anyone, so naturally there would be no harm to these villagers; There is only one goal for the future, which is to return to your own world with your partners; As for hurting the goddess, it is even more impossible, how can that mysterious woman be so easily hurt by others. After taking care of the affairs of Chishui Village, everyone on the four-pointed star has put down their burdens and can work together to drive towards Tianzhu Mountain.

Zhang Xiaohu relied on his own memory to draw a sea chart by hand. He remembered that before he arrived at Tianzhu Mountain, he would pass through an island, but they were not following the correct route now, and there was a high chance that they would miss this island. In that case, their fresh water and food will be a big problem, and the food can also be solved by fishing, but in terms of fresh water, Zhang Xiaohu has not yet come up with a solution, so he can only control everyone's water consumption first, and then find a solution as soon as possible.

Time at sea passed exceptionally fast, and another seven days passed in the blink of an eye. During this time, everyone on the ship concentrated their daily work on the deck, using various ways to catch fish, half of the daily catch was used for the day's food, and the other half was used for drying and storage. The fish in this sea are abundant, and everyone can catch a full harvest every day.

The drinking water problem that has plagued Zhang Xiaohu for many days has finally been solved. Last night, when a few of them were eating a stewed fish pot, they saw the rising heat, and Yichen suddenly thought that they could use distilled water to purify fresh water from seawater that could be used for drinking. Today they tried it, and sure enough, they were able to collect some fresh water. He estimated that about 1 liter of water can purify about 450-500 milliliters of fresh water. However, this process requires continuous heating of seawater, and the demand for fuel is relatively high. Fortunately, there are many things on the ship that are not needed, which can be disassembled and burned. And Zhao Zixuan said that in the warehouse at the bottom of the ship, there are about three or four barrels of that kind of black grease, which are smeared on the wood, which can increase the burning time.

Zhang Xiaohu and Li Yichen have calculated that they can probably use this method to collect about 400 liters of fresh water, plus the original 200 liters of fresh water, which is enough for the four-pointed star to use for 45-50 days, and it is enough for them to reach Tianzhu Mountain in such a long time.

It's the sunniest time of the day, and the sea is shining golden as the sun reflects the sun's rays. It was hot and humid on deck, and everyone went back to their rooms for a nap. Zhang Xiaohu wore a sunhat and came to the deck to inspect the dried fish.

A gust of sea breeze blew, bringing a comfortable cool breeze, Zhang Xiaohu wiped the sweat on his face, turned over all the dried fish, and found a white object floating up and down on the sea surface. In this area, any abnormalities on the surface of the sea are worth noting.

Soon Zhang Xiaohu took Zhao Zixuan and Yan Dacang to get into the boat and row towards the white object.

"Lao Zhang, what do you think that is?" Zhao Zixuan found that the white object seemed to be constantly changing its shape as it rose and fell.

"Hmmm! I look like a coffin! ”

"How dare you think about it!" Zhao Zixuan said, and looked at Yan Dacang again: "Uncle Yan, what do you say?" ”

"I don't say it, I'll know in a while, so I won't bother with that brain!" Yan Cannon lowered his head and rowed the oars, unwilling to look out at a glance.

Just like Yan Cannon said, soon, they saw the appearance of the white object, but everyone's brows were furrowed, and even Yan Cannon couldn't help but wonder, "What is this?" ”

The object was a metal cuboid covered in a layer of brown glass, about 5 meters long, 1 meter wide, and 2 meters high, with a smooth surface and a row of strange codes on the side. This is clearly a precision instrument made by artificiality.

"Bring it back to the ship first!" Zhang Xiaohu hesitated for a moment, thinking that it was better to take this thing to the ship and study it carefully.

Yan Cannon threw out the fishing net, covered the whole machine, carefully checked it, and quickly dragged it back to the boat. When carrying it to the deck, everyone realized that the machine was very heavy, and it took a lot of effort to pull it to the deck.

Zhao Zixuan sat on the deck, gasping for breath, and said with emotion: "Damn!" What is this? Dead and sunk! I'm tired of the master! ”

Yan Cannon was shirtless and said with a smile: "Haha! It looks like a big box, could it contain some weapons? ”

Zhang Xiaohu ignored a few people, staring at the machine, his eyes constantly scanning. I thought to myself: Why does it look more and more like a coffin, will it contain a person? But he also thought about it in his heart, and didn't express his opinion casually.

At first, everyone on board was quite interested in getting together to study the purpose of the machine, and everyone expressed their opinions, of course, more unreliable. But after three days, no results were found. There are no gaps or buttons on the exterior of this machine, and they have no place to start. Everyone's interest slowly faded, except that it was an unidentified object found at sea. Four days later, only Zhang Xiaohu and Li Yichen will continue to study.

"Yichen, do you think this machine really can't be opened?" Zhang Xiaohu put down the Uzi knife in his hand, he also wanted to give up a little, he tried to slash it with the Uzi knife just now, but he didn't even leave a trace. I don't know what kind of metal this machine is made of, how it can be so strong.

Li Yichen gently stroked the glass substance with his hand, and said suspiciously: "From the appearance, we have concluded that this must be artificially made. Since it is manufactured, there may be various structures inside, and traces of splicing or installation should be found on the appearance, how can it not be found at all, is this the beginning of the design of this thing? Her hand unconsciously slid over the glass, drawing various shapes.

Suddenly, a row of symbols flashed on the glass substance, and it kept shining.

"Ahh The two of them exclaimed at the same time, those symbols were very similar to the symbols on the side, but they were not the same content, and there was still a difference.

"Yichen, what did you just do?" Zhang Xiaohu said excitedly.

"I just drew some symbols on it!" Yichen recalled

"Do you remember what was the last drawing? Try again! Zhang Xiaohu said excitedly.

"Hmmm! It seems like this..."Li Yichen said as he drew a triangle on the glass with his hand. Sure enough, a blue light flashed on the glass, and all the symbols from the moment disappeared and returned to the original brown glass.

Zhang Xiaohu also tried to draw a triangle, and the symbols reappeared. They wrote down these symbols in a notebook, tried several other symbols and characters, and found that they had not changed at all, and that the glass matter seemed to be able to recognize only triangular symbols.

They changed their mindset and tried various symbols in different positions of the machine, but nothing else happened.

"Yichen, it seems that we have to crack the secret of these symbols, otherwise we won't be able to continue!" Zhang Xiaohu sat helplessly on the deck and knocked the machine hard.
