100,000 mountains, underground rivers.

With the help of Lei, Si Si moved all the spirit stone mines near the underground river to his bracelet space.

To put it simply, Lei used his great magic power to dig out the spiritual stone mine, and Si Si used spiritual power to put it directly into her bracelet.

In fact, it is already very simple, but the spirit stone mine is really not small, and after a few days, Si Si's spiritual power is almost exhausted.

What's more, because of his humble strength, Si Si's mastery of the bracelet space is not complete, and now it is only with the help of Lei that the entire spirit stone mine is put into the space.

In order to better control the bracelet space and the spirit stone mines in the space in the future, Lei decided to let Si Si be promoted to another level.

In fact, Si Si actually started cultivating not long ago, and it was only a few months since he cultivated to the late stage of foundation building, and now it is a little too fast to upgrade, but Lei still asked Si Si to give it a try.

Every time you raise one level, the spiritual power in your body will also increase exponentially, and with the strength of the current Si Si in the late stage of the construction period, you can barely master the bracelet space, and it should not be reluctant to raise one level more.

Of course, Si Si is the most concerned about this Aitu Lei, and naturally he doesn't want to watch her upgrade fail and her skills are damaged.

In the process of upgrading the division, Lei not only prepared the Nether Grass for her, but also prepared the Gathering Spirit Pill and Nirvana Pill, which were very helpful for upgrading.

These pills were all brought from the Middle Earth Continent back then, and although Lei, who had lived for more than a thousand years, had an understanding of all aspects of knowledge, he was not very proficient in alchemy, and these pills were also used one less than one.

A foundation building period monk was promoted to a junior level and used so many precious pills to help, and only Si Si had such a good life.

And Si Si also lived up to his high expectations, and successfully reached the great consummation of foundation building from the late stage of foundation building, and directly skipped the peak of foundation building, you must know that Aluo's good qualifications also stayed at the peak of foundation building for a long time.

The Si Si, who had successfully upgraded, also complained about this: "Master, since you have such a good elixir, why didn't you take it out earlier, it would have been so hard for us to upgrade before." ”

"A small foundation building period also needs the help of pills, you are embarrassed to say that it is hard."

"Anyway, if there is a shortcut, why don't we take it, or Master, you can give me a few more."

For Si Si's words, Lei must have reprimanded before, but this time in the face of the Scorpion King, the ice wolf, whose strength was not much worse than him, was defeated, and Si Si found another way to put the Scorpion King down.

Therefore, Lei just shook his head helplessly and said, "Your master and I don't know how to refine pills, these are still practiced by Ming Xuan when he was in the Middle-earth Continent before his death. In Middle-earth, these elixirs that can help upgrade are also hard to buy, so don't think about it. ”

"Oh." Si Si didn't force it, and said sweetly, "No matter what, I still have to thank Master and Uncle Mingxuan for allowing me to be promoted two levels in a row." ”

"You don't have to thank us." Lei thought for a while and said, "The peak of foundation building and the great perfection of foundation building are actually similar in strength, and it is more about the pursuit of perfection in the state of mind, and you can be promoted two levels in a row because of your good quality in your heart." ”

"I have a good quality in my heart, how can I not know" Si Si was still a little ignorant.

"Directly speaking, you don't want to be motivated, but you don't have the psychological pressure to escalate. As a result, the cultivation of the foundation building period quickly reached perfection. ”

"In that case, then I won't have to work so hard in my cultivation in the future, just let everything take its course, right," Si Si said happily.

"Are you cultivating hard?"

"Hey, hey, hey"
