With the help of Kong Ling'er, after a few hours, a large pile of vegetation that had been cut down was consumed, and the medicine bottles containing the spirit beans were piled up in a small pile, and the number of spirit beans refined was huge, and there were more than 100,000 grains.

"Okay, Ling'er has worked hard, you go and rest."

Xu Zhexin didn't expect that Kong Ling'er would be able to accompany her and complete all the boring refining work.

But seeing her tired and bored, she was very distressed, so she told her to go and rest.

"Sister, you can rest together."

Ethereal greeted as she sat on the wooden bed.

In this camp, because of the existence of the little one and the second, there are no insects and ants to make trouble, although those beasts occasionally sway outside the camp, but maybe it is the protection of the formation, maybe it is because they know that the people here are not easy to mess with, and there are no fierce beasts that do not have long eyes to dare to come in to forage, and there do not seem to be too powerful spirit beasts around, so the safety of this night should not be a problem.

"Okay, you go first. I'll finish refining the last thing and go to sleep."

Xu Zhexin smiled at her, put away all the spirit beans, and then took out a few simple materials one by one.

"Sister, do you need my help?"

Ethereal Ling'er looked at these simple and shoddy materials curiously and asked, in fact, she was not tired, but refining spirit beans was too boring, at this time, seeing that Xu Zhexin seemed to be making new things, she wanted to watch it very much, and was not in a hurry to rest.

"No help, it's a simple thing, and it'll be ready in a while."

Seeing that Kong Ling'er refused to leave, Xu Zhexin was not reluctant, knowing that it didn't matter if she took a break or not, so he watched with her.

She used the Dan Fire to refine a few things into liquids, shape them after people, polish them, and assemble them, and soon a small object was made.

She shook the pointer in the middle slightly, and saw that the pointer was spinning up and down, and then slowly froze, and the red and blue pointers pointed in one direction each.

"Sister, what is this?"

"Sinan, also known as a compass, is used to distinguish directions, walking in this dense forest, in the dark, it is easy to get lost, it will be much easier to do with this thing, you wait for me."

Xu Zhexin explained first, then took the compass and rose into the air, straight up to a height of 10,000 meters, and fell down after distinguishing the position represented by the direction of the pointer, and then introduced to Ethereal Linger:

"The red hand refers to the south, and the blue hand points to the north, so it's clear."

"Sister, is it that simple? Show me."

The curious Ethereal took the compass and fiddled with it, and found that no matter how many times she turned the pointer, it would never be convenient to point in the direction, and couldn't help but admire: "Sister, such a simple thing, but the effect is not small, you Blue Star people are very wise, this compass is so easy to use, I will also make one to play with."

Ethereal said as she returned the compass to Xu Zhexin, and then sat down and used the rest of the materials to figure it out.

Xu Zhexin also went with her, this kind of simple thing is for Ethereal Ling'er, she will definitely be able to make it successfully after reading it once, but she still explained:

"Ling'er, this compass is simple to make and the principle is simple, but not all places are easy to use, and it will lose its effect when it encounters a place where the magnetic field is chaotic, you have to remember."

"Magnetic field? What does magnetic field mean?"

Ethereal asked puzzled.

"A magnetic field is a field that transmits magnetic forces between physical objects. It is a special substance ...... that cannot be seen or touched, so when it encounters a geomagnetic anomaly or other magnetic thing, the compass will be disturbed by it and lose its effect."

Xu Zhexin briefly explained the magnetic field and the principle of the compass.

"I see, this compass is based on magnetism, I see, sister."

As she spoke, Ethereal had already made another compass.

After the compass was made, Xu Zhexin and Ethereal Ling'er rested separately.

Lying on the wooden bed, looking up at the starry night sky of Jun Tianxing, Xu Zhexin's mood was very excited, and he did not feel the slightest sleep.

Seeing the ethereal child who had fallen asleep quickly on the side, she was very envious, carefree people, life must be very easy and simple, and they can sleep and eat well.

Sleep is no longer a necessity for her, since she can't sleep, let's study the information left by Lord Tianjun.

After coming to Jun Tianxing for so long, except for specific information, she hasn't read the information left by Lord Tianjun well.

In fact, there are not many materials left by Lord Tianjun, and the main records are the information about their exploration of Jun Tianxing and the surrounding starry sky after leaving Blue Star, as well as their return to the cultivation realm.

One night was enough for Xu Zhexin to finish most of it, just looking at it, Xu Zhexin, who was still interested, gradually became heavy.

Then, she began to read the information about Lord Tianjun's search for the way back from the cultivation realm, and as she saw more and more information, her heart sank more and more.

In the second half of the night, when the sky was dark red and the animals in the forest were more active, Xu Zhexin put down the jade book in his hand, his expression was sad, and his emotions were desperate and collapsed for a moment.

However, she was used to being strong, and finally held back and did not let the tears burst, but her eyes were still dazed and depressed.

Her thoughts were mixed, and in the message left by Lord Tianjun, she found that the method she had once wanted to go to the cultivation realm for help would not work.

Because, the cultivation realm is very far away from the starry sky here, and it may take decades or nearly a hundred years to make a round trip.

In other words, to deal with the apocalyptic insect tribulation, we can only rely on the strength of the Blue Star people themselves.

And as the most powerful first person on the Blue Star, she knows the future situation and the situation of the Blue Star people best, and according to the current method, the apocalyptic insect tribulation is almost incomprehensible.

Because of the environment and resources of Blue Star, there are very few Jindan Stage monks who can be cultivated in a few decades, and only those who have entered the Jindan Stage have the opportunity to further their studies through the interstellar teleportation array.

If you can't enter the Jindan period, everything will be in vain, and the cultivation of the foundation building period has no chance of winning in the face of insects, and at most you can only rely on the tactics of 'ants bite to kill elephants" to exchange the sacrifice of human lives for the elimination of insect lives.

But there are only so many Blue Star people, and they can bite a few bugs to death.

It is not feasible to rely on her to collect resources and send them back to Blue Star, after all, she also needs time to concentrate on cultivation, so she can't spend all her time collecting and delivering resources.

This situation... Almost... There is no solution!

Could it be that Blue Star really can't be saved?

Will the brilliant civilization of mankind and her friend Xiaolan disappear?

Xu Zhexin fell into brainstorming, no matter how many possibilities she thought of, she always felt that there was little hope.

More than ten years have passed in the blink of an eye, and the apocalyptic insects are approaching step by step, and for Xu Zhexin and the Blue Star people, what is lacking is the time for them to grow.

But time is relentless, and no matter how people hold on, the pain still flows unwaveringly towards the front.

......

It's dawn.

The hazy light woke up the ethereal child who had a good night's sleep.

In a comfortable mood, when the ethereal Ling'er who got up and stretched turned her head to see Xu Zhexin on one side, she... Stunned.

Because at this time, her sister's eyes were tangled, distressed, anxious, trance, and even empty, which she had never seen before, and this was also the appearance that rarely appeared on monks.

This looks very bad, and if you don't do it, you'll go crazy.

"Sister, has something happened? What's wrong with you?"

Ethereal Ling'er turned over and came to Xu Zhexin's side, grabbed her tightly and clenched her somewhat cold fist, and asked worriedly.

Ethereal Ling'er's voice and movements woke Xu Zhexin into despair.

She looked up at the sky, came back to her senses slowly, and said bitterly, "Ah... It's dawn, Ling'er, you're awake, my sister is fine, it's just in... I am sad about the things of my hometown."

Something about my sister's hometown!? Bugs again?

Ethereal Linger didn't know why overnight, Xu Zhexin suddenly became so worried about things in his hometown.

Could it be that when she was asleep, something happened that she didn't know about, or was there bad news from her sister's hometown?

"Sister, is something happening in your hometown? We have an interstellar teleportation array, if you really have something to worry about, just go back and take a look at it at any time."

Ethereal comforted.

Ethereal Ring's perception of Blue Star was obtained from the books and cartoons Xu Zhexin gave her, and in her heart, Blue Star was a beautiful, rich and interesting world, which made her yearn for it very much.

It's just that this beautiful planet is now facing the danger of being attacked by the Zerg, and that's why my sister and brother came to Jun Tianxing to find a way to eliminate the Zerg.

She especially remembered that when Xu Zhexin told her about herself and Lanxing, she was full of plans and hopes, which made her really admire.

At this time, for some reason, my sister's mood suddenly became decadent.

Although the universe is vast and the starry sky is vast, if there has never been contact between two planets in different locations, it is indeed very difficult to find each other and communicate with each other, but now between Juntian Star and Blue Star, since there is an interstellar teleportation array, it is not a very simple thing to come and go.

She still couldn't understand why her sister was always worried when she mentioned her hometown, but she refused to go back to see it.

"Ling'er, you don't understand, the affairs in my hometown are too complicated, and I can't solve them when I go back."

Xu Zhexin reluctantly smiled and explained to Ethereal Linger.

After listening to Xu Zhexin's words, Ethereal Ling'er turned out to be serious and upright, she looked at Xu Zhexin and said sincerely:

"Sister, you and I will be together for a lifetime in the future, for a long time, and with one benefit. I don't understand something you have to teach me, although I don't have a lot of experience, but I also have some skills, I want to be able to share your worries and solve problems, and I'm not a child anymore, you don't want to tell me nothing."
