Chapter 252 Processing Ore

When several people got closer, they discovered that a large hole of more than one meter had appeared in the original place.

"There may not be enough oxygen underground for a while, so bring this with you."

As he said that, Feng Yuchen gave everyone something like a water cup. The difference was that this one was made of an unknown metal, and there was a small hole in the bottom of the cup. There is also a strap on the water bottle so it can be worn cross-body. When the lid was opened, there was a breathing tube. Xueyin couldn't help but take a sip out of curiosity, and then her eyes lit up.

"Master, I like this."

Hearing what it said, Lin Xi also tried it. Isn't this an oxygen tank?

"Let's go."

Feng Yuchen took the lead and walked towards the entrance of the cave.

This hole allowed Lin Xi to stand up straight when walking in it, but it was a bit narrow for Feng Yuchen and Ye Xi, so they had to keep their bodies down.

Fortunately, the speed of the few people was not slow. After walking for a long time, the field of vision gradually broadened, and the place in front of them could be seen clearly at a glance.

A space of about twenty square meters has been dug out of the ground here, and there is a passage in front that leads to nowhere.

"Xixi, take out the ore."

Lin Xi heard this and took out all the space buttons containing interstellar ores. Feng Yuchen took them and took more than ten or twenty pieces of the same ore. Then he took out two large bottles of unknown black substances from his space. of liquid.

He handed one of the bottles to Yexi, "Spray these on the surrounding mountains."

He also sprayed it on the pile of ore and the ground. After finishing the work, the two bottles of black liquid were also used up.

"Let's go."

Feng Yuchen continued walking along the cave with two people and one pet.

Lin Xi asked curiously: "What is that black liquid?"

"It is specially used to grow ores in the interstellar world. Some ores are also in short supply in the interstellar world. The interstellar people have developed this kind of ore growth liquid. However, the structure of some ores is too complicated and it does not work.

The ores Long Aotian gave you are very common in the interstellar world, and their structures are simple. It is more than enough to use this ore growth liquid. "

Lin Xi: It seems that this was changed from the interstellar system again.

They walked for about ten minutes. The further they walked, the oxygen content inside became less and less. Lin Xi and Xueyin couldn't bear it at first and put on breathing tubes.

This breathing cup may not look big, but it contains a lot of oxygen. Not only that, the small holes at the bottom of the cup can absorb gas and turn it into oxygen. In this way, it is really an inexhaustible "oxygen tank."

After walking for a while, a small space similar to before appeared.

Feng Yuchen and Ye Xi followed the same pattern and arranged another type of ore here.

In this way, the three pets walked and walked. When they came out of another cave, the sky had darkened.

The group of mini robots were also waiting at the entrance of the cave. Feng Yuchen took out a small controller and pressed it, and the group of robots quickly gathered together and transformed back into small balls in the blink of an eye.

"Go back today and come back tomorrow."

The return trip was much faster. It was not so noticeable when it was dark, so Ye Xi took them to a place not far from the parking lot, observed that no one had landed, and walked quickly towards the car.

While still in the car, Lin Xi informed Du Lei to prepare food and bring it to the villa. When they arrived, there was no one in the villa, but the food was already on the dining table.

We walked a lot underground today and the three of us were very tired. After dinner, we went back to our rooms to rest.

Seeing that it was too late, Lin Xi just sent a message to Mother Lin and went to bed.

The next day, when Lin Xi woke up, it was already eleven o'clock. She opened the curtains, and a large swath of golden sunlight shone in through the floor-to-ceiling windows, which made her feel a little dazzling.

"System, sign in."

"Ding, on the 497th day of signing in, you will be rewarded with a deodorant pill."

She opened the box containing deodorant pills, and inside was a snow-white pill. She had gotten one before. She closed the box and sent it into the space.

Ever since Tiantian had a body, Lin Xi always felt as if the system had lost its soul and returned to its original program. It is no longer about what you think about and what you will be rewarded the next day.

There was a suspicion in her mind that maybe Feng Yuchen was not a system, but a truly thoughtful and soulful person.

However, she quickly rejected this idea, how could it be possible.

After gathering her thoughts, Lin Xi washed herself and went downstairs.

Two men were drinking tea in the living room. I didn't know what they were talking about, but the atmosphere seemed pretty good. When they heard the noise, they all looked towards Lin Xi. Xue Yin had already run over and nuzzled Lin Xi.

Ye Xi said: "Get up."

"Ah."

"Are your legs and feet sore?" Feng Yuchen asked with concern.

"She's still sore. She's been practicing for nothing for so long."

Lin Xi smiled and said, "Uncle Master is right."

Then, Ye Xi said: "I just asked Xiao Chen that there isn't much going on over there. We just need to wait for the end. So, I won't go with you today."

"Then where are you going? It's boring to be in the villa all the time."

"I'm going to visit your master's tomb."

After hearing what Ye Xi said, Lin Xi said nothing more.

After dinner, Ye Xi took them to the cave where they were yesterday and left alone.

Feng Yuchen and Lin Xi took Xue Yin into the cave. When they arrived at the first open space, they found that the ore had doubled in size, and the originally empty place suddenly became crowded.

Feng Yuchen took out the ore auxin as usual and handed a bottle to Lin Xi, "Just spray it again like yesterday."

Lin Xi took over and did as he was told, and just like that, the two of them walked along the passage and sprayed without stopping at all. By the time they came out, it was still early.

"Will you come again tomorrow?"

According to the rate of ore growth, I'm afraid those spaces will be blocked tomorrow.

"No, just wait now."

"High technology is indeed useful." Lin Xi couldn't help but sigh again.

"Come up."

"what?"

Lin Xi looked a little confused as Feng Yuchen lowered his body and stood in front of her.

"It's not convenient to walk in a cave, and we still walked so far."

On the way back last night, they had studied it. The hole dug by the robot was almost crossing the small mountain where the forest was located. It was only a few of them who had some skills, otherwise they would not have been able to finish it so quickly.

"It's okay. Didn't we walk so far yesterday? And you're tired too."

"You don't believe me? We're still some distance away from the edge of the woods. You lie on my back and have a rest."

Seeing Feng Yuchen's serious and determined eyes, Lin Xi couldn't refuse anymore, so she climbed on his back.

At such a close distance, she could smell the cold fragrance on the other person's body, and she blushed unconsciously.

This is the first time in her life that a man has carried her on her back.

Feng Yuchen's steps were fast but steady, which made people feel reassured. After a while, she fell asleep on his back.
