It's just that he didn't expect the power of this soul stone to be so amazing, if it wasn't for Guiguzi just now, he was afraid that he would have been completely eroded by the power of that soul.

"This soul stone is pale black in color, and there are many mottled surfaces, it is not pure, it is just a low-grade soul stone!" Guiguzi said lightly: "Take out the remaining two!"

Hearing this, Han Chen couldn't help but be a little disappointed, speaking of which, although this soul stone has a strong danger to the soul, it is an out-and-out treasure.

As long as it is used properly, he can use the soul power in it to refine and improve his soul power, and at this time, Han Chen felt that his soul power, after the impact of the soul power just now, not only improved slightly, but also refined by a few points.

His gaze lingered slightly on the inferior soul stone, and then turned to the other two cold tide stones, both of which also had soul stones hidden inside, but they didn't take them out, but they didn't know the quality.

Han Chen grabbed a cold tide stone with some anticipation, and with a strong grip on his five fingers, he slammed it, and with a 'click', cracks appeared.

With his previous experience, this time Han Chen learned his lesson and slowed down a lot.

Every time you clench hard, it will be accompanied by a crisp 'click' sound, and the cracks on it continue to increase.

It was also five times later, the Cold Tide Stone shattered open, looking at the pale black, Han Chen didn't wait for the Cold Tide Stone fragments to fall, and directly raised his hand and threw it on the table with the broken stone chips.

Guiguzi waved his arm, the strong wind blew, and the debris of the cold tide stone was blown apart. A pale black crystal emerged.

This Soul Stone, compared to the first one, is slightly larger, and the color is a little darker, but it is not too obvious.

Han Chen was slightly disappointed.

Sure enough, I only heard Guiguzi say, "The quality is slightly better than the first one, but it's still a lower grade, let's take a look at the third one!"

Nodding, he reached out and grabbed the third Coldtide Stone. Hold it firmly. After five times.

Bang!

With a muffled sound, the gravel slid down, and Han Chen's gaze vaguely saw a rich black, and he raised his hand to throw it on the table.

Guiguzi waved his hand to sweep away the rubble. A richly colored Soul Stone appeared.

Han Chen immediately set his eyes on it. This Soul Stone was completely different from the previous two. It is three times larger, and the color is even darker, which is extremely pure. It's like a black pearl.

"It's actually a mid-grade soul stone!" Guiguzi said in surprise.

Although he had already guessed before, hearing Guiguzi say this at this time, Han Chen was finally sure, and his face suddenly showed a look of joy.

The difference between the medium-grade Soul Stone and the low-grade Soul Stone is ten times the difference in both the quantity and quality of the Soul Stone, but the value of a medium-grade Soul Stone is higher than that of ten lower-grade Soul Stones.

"Hehe, two low-grade soul stones, one medium-grade soul stone, the harvest is not bad!" retracting his gaze, Guiguzi smiled slightly.

After a pause, Guiguzi continued: "With these three soul stones, plus the small blood demon array, your soul power should soon be able to break through and reach the level of a third-grade alchemist!"

Han Chen's face was a little excited and nodded, for such a long time, the improvement of soul power had always been a headache for him, and the difficulty of his ascension was not inferior to the cultivation of Samadhi True Fire at all.

If it weren't for the sake of being able to improve quickly, he wouldn't have worked so hard to comprehend the formation, and he wouldn't have used all of the blue sky and dark bamboo essence to comprehend the small blood demon array.

And after so long of hard work, he has completely mastered the Little Blood Demon Array, and now he has obtained these three Soul Demon Stones, and next, he will officially start to improve himself.

Raise your hand and take out two jade boxes from the empty ring, put a low-grade soul stone and a medium-grade soul stone into it, and put it away, leaving only the first one, which is the lowest quality soul stone.

Then he turned around and walked out of the hut, came to the gate of the courtyard, and said to the guard who led him the way yesterday: "Brother Xiao, I am going to retreat for a few days, please help me pay attention to it, don't let people disturb me!"

This guard's name is Xiao Hu, and he is also very respectful to him, Han Chen naturally doesn't put on any shows, so he directly calls him Brother Xiao.

"Don't dare to be!" Xiao Hu hurriedly waved his hand, then patted his chest and said: "Brother Ye Yun, although you are in retreat, I will tell the sixth master about this later, and I will not let anyone disturb you!"

"Then there is Brother Lao Xiao!" Han Chen nodded with a smile, then turned around and returned to the small courtyard.

In the next few days, he wants to arrange a small blood demon array to improve his soul power, and he doesn't want to be discovered by others, so he can only do this.

Back in the hut, Han Chen first put all the tables, chairs, furniture, etc. in the room into the empty ring, and looked at the empty room, he nodded with satisfaction.

Then, with a flick of his fingers, he saw demon cores of different colors flying out of his empty ring, controlled by him with his soul power, and suspended in the air.

There are a total of seventy-two demon cores, all of which are first-order demon cores, and there are all kinds of attributes.

In fact, speaking of which, the best arrangement of the formation is not the green jade stone, but the magic core, after all, compared to the green jade stone, the aura in the magic core is more intense, far from being comparable to the green jade stone.

After taking out all the demon cores, Han Chen scattered the seventy-two demon cores around the hut one by one according to some mysterious direction, although the area of this hut was not large, but for Han Chen, it was more than enough to arrange a small blood demon array.

After placing the last demon core, Han Chen walked to the center of the hut, turned his head to look at Guiguzi and said, "Teacher, help me cover my breath later!"

The small blood evil array is formed by gathering the yin and evil qi and endless resentment between heaven and earth, and when the array is arranged, it will cause visions, and if it is detected by others, it will inevitably cause some trouble.

"Hmm!" Guiguzi nodded and smiled.

Seeing that Guiguzi agreed, Han Chen didn't say anything more, retracted his gaze, and exhaled softly.

Immediately, his face froze, his hands were folded in front of his chest, and his fingers changed, and he quickly formed a knot.

Compared to the basic formation of the entry, this small bloody formation is relatively much more advanced, and the seal knots required for the formation are also a lot of dodge, with a total of one hundred and eight seal knots, not only must they be completed in one go, but there must be no difference in the middle.

After this period of comprehension, Han Chen has already mastered this array seal, and he usually practices diligently, and at this time, the seal is not only extremely smooth, but also fast.

The fingertips changed, and one by one the knots were completed, and after ten breaths, Han Chen's fingers paused, and the last knot was completed.

"Little Blood Formation, Condensation!"

With a soft drink, Han Chen's soul power rushed out from the center of his eyebrows like a flood that opened the floodgates, scattering in the air around him.

And the next moment, the seventy-two demon cores around the hut quickly faded until they were completely illusory. (To be continued......)
