At this moment, Song Chenxi and Yu Ying had already placed all the crystal cores on the table. They were categorized by color.

There were 1,000 red crystal cores, 800 orange crystal cores, 600 yellow crystal cores, 400 Green Crystal Cores, 200 Green Crystal Cores, and 50 Blue Crystal Cores... ... ​​

Yu Ying: "I never dreamed that I would be able to see so many crystal cores.

With all these added up, I feel like I can buy the INN."

"Is it really that valuable? " Song Chenxi looked at the pile of crystal cores on the table. At first, she was quite shocked. After a long time, it would just be like that.

Yu Ying said, "Chenxi, to recover spiritual power, you have to extract the power from the crystal cores.

"The first time you use it is a red crystal core, and so on.

"Try it. How much can you use the first time you use a crystal core? "

Song Chenxi picked up a crystal core. "How do you use this thing? "

Yu Ying said, "put them in your palm and refine them with your mind.

"If there is no power in them, the crystal cores will automatically disappear and turn into a pile of powder. "

Song Chenxi nodded. Following Yu Ying's instructions, she placed a red crystal core in her hand for the first time.

It could be said that with a single breath, the crystal core turned into white powder.

"Chenxi, your body is too strong. This is too fast. With your speed, the crystal cores on the table might not be enough for you, " Yu Ying said. She also wanted to use the crystal cores. However, she did not dare to take one. Chenxi seemed to be easy to talk to. However, when they really came into contact... They realized that she had a cold personality.

If they angered her, they might be able to leave. It wasn't easy for her to live a peaceful life. Yu Ying decided to hug song Chenxi's thigh and never let go.

Song Chenxi Smiled faintly. "How many crystal cores do I need to absorb before my spiritual power recovers? "

Yu Ying shook her head. "I'm not sure about that. The spiritual power in my body has only recovered by 20% .

"I accidentally obtained a lot of red crystal cores, about a few thousand of them. "Then, I refined them all, and only then did I recover to my current state. "

Song Chenxi pointed at the Crystal Cores on the table. "take a few high-grade ones and try them out. I'll take a look at your results. "

Yu Ying was overwhelmed by the favor. She took two yellow crystal cores from the table and placed them on her palms to refine.

Song Chenxi watched from the side and realized that Yu Ying's refining speed was really very slow. For a full two hours, the two crystal cores turned into powder.

Yu Ying opened her eyes. "Chenxi, I feel like I have endless energy in my body now.

My spiritual power is much stronger than before.

Perhaps it's because I didn't cultivate much when I was young, so I don't have much spiritual power.

Even if I recover, it won't be of much use. After all, here, besides cultivating spiritual power, you can also cultivate Mana.

Mana is directly converted from Crystal Cores, so it's easier to cultivate than spiritual power."

Song Chenxi: "Is Mana really easier to cultivate than spiritual power? "

Yu Ying nodded. "But there's a requirement to cultivate Mana, which is that the cultivator must leave two Dantian.

Otherwise, it would be very difficult to achieve. "there must be a place to store Mana before it can be used by others. "

Song Chenxi Really did not know much about cultivation. She used her clone to check her Dantian.

She discovered that there were two Dantian, one was pure white. The other was black. Could it be that she could cultivate Mana?

"Yu Ying, I have a black Dantian. Can I train Mana? "

Yu Ying was shocked. "Chenxi, are you joking with me?

You are from the spirit world. The probability of having two Dantians is one in ten thousand."
