As long as Song Xiaoxiao was still by his side, Dugu Mo's heart was half relieved and turned around.

It's just that he can't figure out what's going on, Dugu Mo has read no less than 100 ancient books since he was a child, but he still hasn't found the root cause.

Song Xiaoxiao is by his side, but he can't see it, is it invisible? This idea shocked Dugu Mo a little, even how to cultivate to a profound person, he has never heard of anyone who can be invisible, so Dugu Mo has been reluctant to think in this direction, it is incredible.

Dugu Mo simply sat down and waited for Song Xiaoxiao to appear.

As expected, two hours later, Song Xiaoxiao appeared in the position where she was standing before, and her figure changed from illusory to real.

Seeing Dugu Mo's dumbfoundedness, Song Xiaoxiao couldn't help waving his hand in front of his eyes, "Big brother!" ”

"What skill did you trigger, you can actually become invisible." There was a hint of joy and a hint of envy in Dugu Mo's tone, but it was only for a moment.

Maybe he was afraid that Song Xiao would be too strong in the future and didn't need his own protection at all.

Sure enough, Song Xiaoxiao knew the truth.

"Big brother, thanks to you, I can have such a big opportunity, I have a hidden exercise, but this invisible ability can only be used once a day, and each time it does not exceed twenty minutes." Song Xiaoxiao's face was filled with a bright smile, like a hundred flowers blooming.

"But you just disappeared for more than two hours." Dugu Mo was a little puzzled.

"Just now thanks to you, you gave me the opportunity, I was able to have an epiphany, and it was in the epiphany that this exercise was triggered, and I only discovered it in my consciousness, this invisible need for spell casting, the duration of time, including what kind of person can see through, is as if engraved in my mind, listed in my mind."

Song Xiaoxiao breathed a sigh of relief, looked at Dugu Mo and continued, "It's just that I'm only in the initial stage now, so the time for invisibility is limited, and I can't use it as I like, but now this has given me a big surprise." This exercise seems to have a lot to do with the wood attribute in the five elements, and as long as I cultivate and improve in the future, I can continue to be invisible for more time. ”

"Treasure hunting, stealth, it's a miracle." Dugu Mo muttered.

"Girl, have you ever heard of the Sumeru Stone?"

"Sumeru Stone? No. ”

"Yesterday you saw that I took out a lot of things in my hand, and you once asked me how I was like a treasure, and I could catch something at the touch of a hand. That is the Sumeru Stone, which contains the universe and can contain all things in the world, excluding living things. The space of low-level Sumeru stone is limited, and the high-level Sumeru stone evolves by itself, and the space for improvement will be broader with evolution. As long as a person in the practice refines the Sumeru stone, and his mind moves, the things at hand can be included in the Sumeru stone. Therefore, the Sumeru Stone is also known as the Space Stone, and only the Great Gate Sect has heard of this concept, but there are very few owners. ”

"In this way, the Sumeru stone is particularly precious." Song Xiaoxiao listened to Dugu Mo's brief description, and had a desire to get the Sumeru Stone in her heart.

"Of course, because I am the next head of the Dugu family, I can get a Sumeru stone, and when I go to Changbai Mountain, I can give you one."

"Such a precious thing, if you give it to me, I'm afraid you will be blamed by the family." Song Xiaoxiao naturally knows the intrigue and power that exist in everyone's organization.
