Travel through the 90s with the system, dig your own grave first at the beginning

Since there is no rush in terms of time, just take it slow. Things have already been decided, so just take it one step at a time.

Gu Zishu was not in a hurry to go back. He couldn't let his skin become better and his hair become shorter after a night's sleep. The other people in the family would probably be thinking about what to do in the evening.

Fortunately, there are not many people in the mountains here, but there are quite a few spiritual plants, magical herbs, monsters and so on. Gu Zishu thought about the alchemy and weapon refining he had been thinking about, and he might as well stay here for a while. By then, his hair will grow longer and his skin color will be a little more tanned. Even if there is a little difference from before, this can be explained by makeup. Anyway, he wears a lot of clothes in the winter, so it doesn't matter what's on his skin.

Gu Zishu picked some spiritual herbs, took some time to go down the mountain, exchanged some spiritual stones, bought a cauldron for refining medicine, and turned back up the mountain.

As for the rumor about the girl who had transcended tribulation that was spreading like wildfire down the mountain, Gu Zishu was not afraid at all. With her current level of cultivation, basically no one could see through it. Moreover, her face was covered with blood scabs at the time, and the onlookers didn't even see what she looked like.

However, despite this, Gu Zishu still had to use a mask to slightly change his face.

After buying what she needed, she didn't stay at the foot of the mountain for long and went straight back into the mountain.

He injected spiritual energy into a house-shaped magic tool he had bought, and suddenly a two-story bamboo building stood up on the spot.

It has everything you need for the kitchen and bedroom, which is simply a must-have for home and travel.

Gu Zishu carried food with her, and she lived a peaceful life in the mountains. She went into the mountains to pick herbs, hunt, and occasionally fight with a powerful monster to practice her skills and make pills. Although there was no one to guide her, after dozens or hundreds of times of practice, Gu Zishu was able to make basic pills very well.

As the days passed, Gu Zishu originally thought that his hair would grow as long as before in ten days or half a month. However, a month passed, and although Gu Zishu's alchemy skills had improved slightly, his hair showed no sign of growing longer, and his skin was still as fair and tender as before.

"Ji Liang, when can I go back? If I stay here for a few more months, I might fail the exams." Gu Zishu was very worried. Even though she was Tiandao's biological daughter here, she still had to take exams when she went back.

"The hair of high-level cultivators is a magical tool for cultivation. You think it is like that of ordinary people, and it can grow as you wish. However, although your hair cannot grow long, you can use illusion to change your appearance. With your current cultivation level, you will still look the same after thousands of years, so you must learn illusion in advance. Otherwise, in the real world, people your age will have wrinkled skin, while you still look like 18 years old. This is not justified."

Only then did Gu Zishu realize that it was so difficult to grow hair.

However, this illusion does need to be practiced, but I don’t have such a thing on hand.

Gu Zishu thought about the token of the library in his backpack, wondering if he could summon it here. He prepared the food in the backpack and cooked a few dishes. Then he took out the token and started calling people.

She originally thought that she might not be able to call the person over, but before she had to wait long, the familiar child appeared in front of Gu Zishu, and he looked a little taller.

The other party came over and saw Gu Zishu and was obviously stunned for a moment, "You little errand boy?"

"Yes, long time no see. I have something delicious to treat you." Gu Zishu said with a smile.

The spirit of the weapon looked at Gu Zishu. The last time they met, he could still tell the depth of this girl, but now he couldn't. After several years, she still looked the same as before, without any change.

Sure enough, Tianji was right when he said that this girl had some connection with this world. Thinking about the thunder not long ago, the spirit of the weapon was moved. It seemed that Tianji was not fooling around. Things had already come true, so it was understandable that this girl was like this now.

"Okay, it's rare that you think of me when you have something good." Qi Ling sat next to Gu Zishu with a smile, followed Gu Zishu's example, and started to eat the food on the table.

Halfway through his meal, Gu Zishu spoke up, "I came here to ask you to help me with something. I want to learn something, but I don't have a master. Can you let me go into your library and take a look?"

"Okay." The spirit of the weapon responded readily. The contribution value for saving the world was definitely enough.

"Hey, is it so straightforward now?" Gu Zishu was surprised for a moment.

"I can't help it. I've already eaten half of this thing. I have to be grateful for what I have received. But you can only read it in the library. You can't take it out." The spirit of the weapon emphasized.

"That's for sure." Gu Zishu agreed immediately.

If you don’t want to take it out, then don’t take it out. You can remember it in your mind anyway.

The spirit of the weapon waved its hand, and a miniature version of the library appeared not far away. "Go ahead."

Gu Zishu nodded at the other party and walked directly into the library. It looked small from the outside but very large on the inside. The large shelves were filled with jade slips and books.

When Gu Zishu walked in, there were other disciples of Qingyang Sect reading books inside, and no one was surprised to see Gu Zishu come in.

Gu Zishu heaved a sigh of relief when he saw that no one was paying attention to him. He first went to the alchemy area to select a jade slip book and read it, and then went to the weapon refining area.

Staying in the library, she felt calmer and no longer restless. She was immersed in the different books. She no longer felt hungry or sleepy, and there was no day or night in the library.

Gu Zishu didn't know what time it was while reading the book. At the beginning, he read books selectively, but later he read them one by one in order. The things in this immortal cultivation plane were all very interesting. Anyway, when he finished the last book, Gu Zishu was stunned.

"Is that all?" Gu Zishu muttered.

"What can I have? How long have you been here? A little bit of food. I've shown you all the books I've collected over the years. These are not common things in here. They are all treasures, you know." The weapon spirit's angry voice sounded in Gu Zishu's ears.

"I know, I know. Thanks to you. Next time when I have something delicious, I will definitely not forget you." Gu Zishu said quickly.

"Okay, get out of here." After the spirit of the weapon said that, Gu Zishu was thrown out of the library by the spirit of the weapon. Gu Zishu looked at his small bamboo house. The things he had packed up were now overgrown with weeds. The peach trees he had planted with peach seeds had now grown into many trees.

"Ji Liang, how long have I been in the library?"

"10."

……

Gu Zishu really didn't expect it would take so long, more like 10 years. He hadn't eaten, drunk or slept. Gu Zishu, who had originally felt nothing, suddenly felt very greedy and sleepy.
