Su Shu asked a lot about the ancient world, and he didn't know where he was, he only knew that he was underground, but this underground was not necessarily in the terrestrial secret realm, so he asked:

"And how do I leave?"

The ancient man was a little depressed when he heard this, it could speak when it had a memory, but Su Shu was the first person to chat and talk with it, and it liked the smell of Su Shu very much, so it asked a little reluctantly:

"Are you leaving?"

Seeing that the flames in its eye sockets became very weak, Su Shu couldn't help but touch its little head comfortingly, the touch was not cold, but there was a strange warmth, she nodded and said:

"Yes, I have friends waiting for me, and if they can't find me, they'll be in a hurry. ”

Seeing that she was very firm, Shen Gu sighed and said in a lost tone: "Okay, you come with me, I'll send you out!"

Stygian Gu closed the door of the Dark Moon, and then took Su Shu to open another cave door, and clusters of green flames burned in the cave door, illuminating the entire stone cave as if it were day.

Su Shu followed the Styx for a while, and when she saw a small pool in the cave, she felt a strong aura fluctuation.

Feng Yu had already flown out of the sea of knowledge, he looked at the white thick liquid in the waterhole in disbelief, and shouted very excitedly:

"Sister, there are so many spiritual milks here!"

Su Shu was slightly stunned when she heard this, is it a spiritual milk? That is an extremely rare treasure of heaven and earth! It can be said that there is no bottleneck in cultivation, and there is no need to worry about the instability of cultivation, but how can there be spiritual milk here!

Su Shu walked quickly to the waterhole, and the rich aura rushed to his face, with a fatal attraction, Su Shu suddenly felt that he couldn't move his feet.

One drop of spiritual milk can be sold for a sky-high price, but there is a small pool in front of her, and Su Shu feels that she may not have woken up.

Su Shu was still just staring at the spiritual milk with red eyes, but Feng Yu didn't care so much, he stood directly next to the waterhole and drank it, his excited eyes were red, after drinking it, he would be able to advance again, and then he would be able to help his sister more!

Seeing Su Shu staring at the waterhole motionlessly, his expression was very excited, so he asked with some curiosity:

"Is there anything nice about this water?"

"Water?" Su Shu forcibly looked away at the Immortal Gu, unable to understand how the spiritual milk that could make the entire immortal cultivation world flock to it had become worthless water in the eyes of the Immortal Ancient!

"yes, isn't this just water? I use it every day to bathe!"

Feng Yu, who was originally eating happily, heard that the little skeleton was bathing in it every day, and he didn't stand firm and fell into the spiritual milk all of a sudden, which was also too disgusting, so didn't he eat the little skeleton's bath water?

But when he felt the surging aura in his body, Feng Yu's nausea dissipated instantly, the bath water was a fart, and he drank the bath water with this spiritual milk.

Su Shu ignored Feng Yu's fluttering in the spiritual milk, she was angry with the internal injuries of the ancient world at this time, it was too tyrannical, can you be a little more arrogant?

"Don't you think there's a lot of aura in here, if you eat it, it's very beneficial to cultivation!" Su Shu tried to take a class with the Immortal Gu, it was not good to be so extravagant........

The Ancient Immortal tilted its head, and it spread its hands helplessly:

"I don't rely on aura to cultivate! Also, although I have a mouth, I can't eat it!"

Su Shu looked at the empty stomach under the ribs of the Underworld, and suddenly felt embarrassed, she smiled and said:

"Also, you're different from humans in the first place, but I think it's worse. ”

After finishing speaking, she turned her head to look at the spirit milk, she squatted down and looked at the Ancient Dao:

"Since this is useless to you, can you give me some?"

Shen Gu nodded without the slightest hesitation, and waved his little hand very arrogantly: "Naturally, you can bring as much as you want!"

Su Shu couldn't help but bend her eyebrows when she heard this, the corners of her mouth rose to reveal eight teeth, and she stretched out her hand and touched Minggu's little head: "Thank you!"

"Sister, sister, come here, this spiritual milk is so delicious. Feng Yu's excited voice sounded, urging Su Shu repeatedly.

Looking at the phoenix feather soaked in the viscous spiritual milk, Su Shu couldn't help but smile again, stretched out her finger and scraped a small piece of spiritual milk and put it in her mouth, and the rich spiritual energy instantly filled the entire mouth, completely melting in the mouth.

Before Su Shu had time to reminisce, the aura in her whole body suddenly exploded, and a severe pain swept through her body, making Su Shu can't help but want to shout out in pain.

"Su Shu, what's wrong with you?" Seeing that her face suddenly became distorted, Shen Gu couldn't help but be a little frightened for a while, and it didn't dare to touch Su Shu, so it could only be anxious.

Feng Yu heard the anxious voice of the Stygian Ancient, and hurriedly got out of the spiritual milk, he flapped his wings and flew over, standing on the head of the Immortal Ancient, looking at Su Shu worriedly, and said in an anxious tone:

"Oh no, my sister is a human being, and she can't bear the aura in the spiritual milk at all, and the aura in her body is rioting. ”

It was the first time that Ying Gu heard Feng Yu speak, so he raised his hand and grabbed him from his head, looking at him curiously.

Feng Yu was already very worried about Su Shu, and at this moment he was pinched in his hand by the Stygian Gu, and his heart suddenly became angry, he twisted his body desperately, trying to break free from the clutches of the Immortal Gu, but it was useless, and finally he had to shout loudly:

"What do you want to do with this little skeleton? Release me, I'm going to be pinched to death by you!"

Only then did he realize that this little skeleton was so powerful, and he didn't even have the slightest chance to resist in front of it. He looked at Su Shu even more anxiously, what if this little skeleton wanted to hurt his sister!

Hearing this, the ancient world immediately let go of its hand, and it touched the back of its head a little embarrassedly, and said apologetically:

"I didn't mean to, I just didn't control the dynamics. ”

Feng Yu hurriedly flapped his wings and flew up, not even paying attention to his feathers falling on the hands of the Immortal Gu, he flapped his wings in the air, blocking in front of Su Shu:

"Forget it if you didn't mean to, I forgive you. ”

After observing for a while, seeing that this guy really didn't mean to hurt them, Feng Yu couldn't help but quietly breathe a sigh of relief, and then continued to look at Su Shu worriedly.

Su Shu's current situation is very bad, the tyrannical aura is rampaging through her body, frantically destroying her veins, and she has to endure the severe pain while running exercises to guide these aura.

But there are too many of these auras, and they can't fit in the body at all, if there is not enough space to accommodate these auras, Su Shu's body will be blown up by these aura.

Now the only way is to force the foundation.

But Tsukiki is the most taboo to be disturbed, she doesn't even have the most basic defensive formation around her now, if someone interrupts halfway, then she is basically useless, but she can't manage so much now, she can only fight.

After making up his mind, Su Shu no longer paid attention to the tyrannical aura in his body, but concentrated on compressing the aura in the dantian.

The process of building the foundation is to compress all the spiritual energy in the dantian into spiritual liquid.

This process is simple and simple, difficult to say, simple is to keep compressing the aura, the difficult thing is that there is no Zhuji Dan's auxiliary foundation building success rate is only fifty percent.

Su Shu didn't think about it so much, all her thoughts were now focused on compressing the aura.

After repeated compression and tempering, the aura finally turned into a drop of spiritual liquid and gathered in the dantian.

Su Shu was slightly happy in her heart, she successfully compressed the first drop of spiritual liquid, and with experience, the rest will be much smoother.
