Everyone's hearts trembled, and their expectant eyes fell on Ling Xi again.

She has already given them too many surprises, and perhaps there will be more unexpected things in this little head.

Yunfei asked: "What can I do?"

"You can use sunlight to evaporate seawater and turn it into distilled water. Distilled water is drinkable and is no different from the water we usually drink."

Knowing that her words made them confused again, she smiled slightly and said: "Let's not talk about it for now. I will think of a way tomorrow to see if there is any way to achieve this."

No one said anything, they just fell into deep thought.

She said tomorrow, then wait patiently for tomorrow.

If they can even solve the water source, then they may really be able to break through this road of death.

Murong Yunfei looked at Ling Xiao who returned to the cabin with a basin of sea water and said calmly: "Let's take a look at Li'er's so-called compass first."

No one said anything, everyone's eyes were focused on Ling Xi.

She picked up Ming Ye's long needle, tore off a piece of tissue paper, and placed the paper on the water in the basin to let it float.

She handed the silver needle to Ming Ye and looked at him: "Cut it off for me. I only need a small section."

She indicated the position with her fingertips, and Nangong Mingye took it and pinched it gently, directly breaking the silver needle.

"Leng Qing, let me lend you your sword." She said again.

Leng Qing took out the sword from his waist and handed it to her: "Be careful."

His sword was too sharp, and there was a chill in the blade, so he was afraid that he might hurt her accidentally.

"Don't worry, it's not like I've never used a sword before." She smiled and pulled the long sword out of the scabbard. As soon as she took it out a little bit, she felt a cold air approaching.

She calmed down and couldn't help but mutter: "Things are like masters."

Leng Qing just pursed his thin lips and said nothing.

Ling Xi only pulled out a small section of the sword, and then took the silver needle and sharpened it on the sword.

After grinding for a while, she loosened the silver needle and touched the sword body with the silver needle. She felt a magnetic force between the silver needle and the sword body, so she returned the sword to the cold air and placed the silver needle on the paper.

On the surface.

"Can you guarantee that this table will not move around?"

As soon as she finished speaking, Chu Han's palm fell on the table.

Because there were wind and waves on the sea, you could still see ripples visible to the naked eye in the water in the basin ahead of you. But after Chu Han put his palm on the table, the ripples disappeared, and the water surface became completely still, leaving only

The piece of paper with the silver needle floating on it is still slowly fluttering.

After turning for a while, the note and silver needle stopped.

"Look," Ling Xi's long finger pointed at the tip of the needle, "This direction points to the south. This is the principle of the compass. You are much more familiar with the sea area in this area than I am, so you should be able to judge where the compass is pointing.

The South is not correct."

"Correct." Zongzheng Chuyang is quite familiar with this sea area, and the end pointed by the fine needle is indeed the south.

Not only Zongzheng Chuyang, but also Chu Han nodded: "The direction you are pointing is correct."

"That's it. If you lose your way in the future, use this method. If you are afraid that you can't tell which is south and which is north, you can make a mark on the needle."

She could tell the difference at a glance because when she put it down, she knew which side had been rubbed, but the thickness of both ends of Mingye's silver needle was the same, so people might not be able to recognize it if they were different.

"Why did you keep sharpening the silver needle on the deserted sword surface just now?" Murong Yunfei looked at the small silver needle and looked very interested in what she said.

"Grinding it for a while can make the silver needle magnetic." Seeing their confused faces, she added: "If the needle becomes magnetic and then it comes into contact with something like cold iron, there will be a force between the two objects."

Just like what she just showed, if you touch the silver needle to the sword surface, there will be a magnetic force between the silver needle and the sword surface, driving the silver needle back to the sword.

When she did all this, they also noticed this process. They were not stupid people. Listening to what she said, everyone probably understood this principle.

"Are all needles okay?" Yunfei asked again.

"Basically, it's okay. Anyway, you can grind it and see if there is a driving force between the two objects. If there is, then it's fine."

Yunfei nodded and said nothing more.

"Now that we have thought of a way to indicate the direction, we will just wait until tomorrow to see if Li'er has a way to solve the water source problem for us."

Zongzheng Chuyang looked at Ling Xi, with more than pity but also appreciation in his eyes: "I didn't expect our little woman to know so much."

Ling Xi pursed her lips, feeling a little guilty: "I didn't invent these, I just picked them up based on existing theories."

"So, were these so-called theories common in your era?" Chu Han began to be a little curious, what kind of world was they in that era?

Ling Xi nodded and said truthfully: "It is indeed very common. The era you are living in now is indeed much behind our time."

As soon as she finished speaking, she hurriedly explained: "Don't be angry, I didn't mean to slander this era, but what I said is true."

No one spoke, no one was angry. The progress of an era cannot be changed by them alone.

"Anyway, after the sun comes out tomorrow, I'll try to see if I can get some distilled water. However, using the heat of the sun to heat the sea water is possible, but it's too troublesome and not very efficient." She looked again.

Looking at everyone, he suddenly smiled sweetly: "Maybe I will need your help then."

They are all martial arts masters. Everyone has profound internal skills. Isn't it easy to get some heat?

"In this case, let's call it a night." Chu Han did not forget what she just said.

Mingye said he would give her acupuncture that night, and he didn't want to delay them.

Everyone understood what he meant, and no one said anything. As long as Ling Xi's body was involved, everyone was extra cautious.

Nangong Mingye stretched out his hand to hold Ling Xi in his arms and returned to the cabin.

Even if he couldn't be sure whether she was pregnant, he would still have to inject needles into her abdomen from tonight to force the poison in her body into the uterine cavity bit by bit.

There can be no hesitation in doing anything, no matter how cruel it is, it must be done.

After everyone dispersed, the entire cabin fell into silence again, and the wind occasionally blew by, bringing a cool breath.

People's hearts are still impetuous, but with this breeze, their restless hearts have finally calmed down a bit.

No matter how many dangers and difficulties await them ahead, they can only keep their heads down and keep going. After all, the road is still long.
