Lin Lei returned to her room, plugged in the door, and silently said, "Return to space."

The moment the pet cat entered the space, it sensed Lin Lei's aura and rushed towards her.

The pet cat used its body to rub against Lin Lei's push and sweetly said, "Master, I missed you so much. Why have you only just come in?"

Lin Lei picked up the kitten with both hands and walked back to the bamboo house.

"I have to find time to come in. Do you have a name? Let me give you a name!"

The pet cat happily said, "Master, I don't have a name. Master, please help me choose a name."

Lin Lei pushed the door open and carried the kitten to the bed. She touched the pet cat and said, "Are you a boy or a girl?" The kitten's cute voice was like a girl doll.

The kitten said shyly, "Master, I'm a girl! The space is low-level now, there's no way to transform."

It could even transform into a human. This was really not good. Upgrading the space was a big deal.

"How about Xiao Mi?" Lin Lei touched the kitten and said, "This cat is so soft!" She had always wanted to have a cat in the past!

The pet cat was touched and turned over. It replied lazily, "Well, I'll listen to Master."

"Then Xiao Mi, what is an energy stone?"

"Master, come here." Xiao Mi jumped down. She slowly walked to the bookshelf and picked up a green book, placing it in Lin Lei's hand.

Lin Lei picked up the space upgrade guide written on the book, turned around, and sat down on the bed, reading it.

Space was divided into five levels. It could be upgraded with blue, green, red, gold, and black stones.

The so-called energy stone was the stone in the bottom layer.

Wasn't that similar to jade? Then where could she find it? Earth was so big, and there were so many countries...

Xiao Mi sensed Lin Lei's thoughts and said, "Master, if I sense the stone, I will tell Master."

Lin Lei raised her head in surprise and said, "Xiao Mi, can you sense my words?"

"Yes, I can sense Master's thoughts in space." Xiao Mi looked at Lin Lei proudly.

Lin Lei remembered that she had come in to look at the materials she had collected in the past. It was difficult to collect food in the post-apocalyptic era, and there was basically no food in space.

"Xiao Mi, give me the list to see."

Xiao Mi jumped out of bed and went to the bookshelf to fetch it. It was a big folder.

Lin Lei looked through some of the clothes and weapons she had collected. The weapons from the apocalypse were no longer useful. Lin Lei took the opportunity to collect a batch of them. There was also some medicine and quite a number of antibiotics.

But they're not for sale. The clothes need time. The drugs and the guns are too much.

Lin Lei looked at Xiao Mi with Shining Eyes.

"Xiao Mi, can you plant the land outside? And can the spring water wash the meridians?"

Lin Lei was so excited that she thought that this body was very strong. If she were to be baptized by the spring water, she should be able to go to the next level.

If she could plant the land, the time here and the time outside would be 100:1. Anything would be fine.

While Lin Lei was daydreaming, Xiao Mi had already placed what she needed on the bed.

"Master, the spiritual spring is at the primary level now. It can wash away the toxins in Master's body and beautify her face. When she upgrades in the future, she can still maintain her youth and increase her strength."

"As for the land outside, it can be planted. Right now, the primary level can only be planted with vegetables and grains. It will mature very quickly. Master can plant it as long as you have the will to plant the seeds."

Xiao Mi thought for a moment and added, "Master can eat things from the space for a long time to increase the spiritual energy. In the future, there will be all kinds of books to guide master when the space upgrades."
