Zeng Cheng entered Baicaoju, went straight to the second floor, came to a door with the word "Spirit Stone" written on a small seal, opened the door and walked in.

Entering the room, inside is a vast space.

In fact, Baicaoju is not as simple as it seems. Many of the rooms in him were built using the space formation, and they were the real Nasumeru mustard seeds, and the space inside didn't know how wide it was.

Take this room where the spirit stones are stored as an example, according to Zeng Cheng's estimates, the area inside is not less than 100,000 square meters, and the height is a full 100 meters.

As an immortal emperor who is not short of money, the spirit stones in the hands of the Baicao Monk are naturally extremely numerous. So it's no surprise to store in such a huge space.

It's just that this room is very empty now, just in a corner, there are so many piles of spirit stones, and the space occupied by these spirit stones is not even one ten-thousandth of the entire space.

There are four piles of spirit stones, and the largest pile has about ten cubic meters, which is a pile of pure white medium-grade spirit stones. Judging from the relevant records obtained by Zeng Cheng, there are a little more than 100,000 pieces of this kind of spirit stone.

The second is a pile of milky white lower-grade spirit stones, with five or six cubic shapes, and the number is more than fifty thousand.

Again, there is a pile of colorless top-grade spirit stones, with a volume of only a little more than a cubic meter, and the number is more than 10,000.

These three grades of spirit stones are basically useless with the cultivation of the peak of the Hundred Herb Immortal Emperor, because such spirit stones are almost useless to him, so they are stored very little. What is left behind is basically all his inventory.

And the least is the innermost small pile of colorless and pale gold superlative spirit stones, Zeng Cheng counted carefully, just a thousand pieces, neatly stacked in the corner. This grade of spirit stone was needed for the cultivation of the Baicao Monk, and although it was originally stored a lot, it was basically used up by him, and only the last thousand pieces remained.

Looking at the few spirit stones left, Zeng Cheng couldn't help but think of the helplessness of the Baicao Monk when he chose to feather. Because for him, a powerhouse at the peak of the Immortal Emperor, these spirit stones were not enough for him to cultivate once.

In fact, in the last few hundred years of the Baicao Monk's life, he did not use spirit stones to cultivate again, otherwise his cultivation would not have fallen from the peak of the Immortal Emperor to the early stage of the Immortal Emperor.

In the face of the powerful laws of the universe, even a strong person standing at the pinnacle of civilization is still so powerless.

Baicao Jushi is a proud person, and when the end of his life is about to come, he does not choose to linger or be hysterical, but chooses to feather himself and end his life early.

Zeng Cheng couldn't imagine what kind of disaster his encounter would be for the earth if Baicao Jushi was an evil person, or a person who was not strong in self-control. Because for an immortal emperor-level powerhouse, it is not difficult to destroy a galaxy, let alone destroy a small earth.

Therefore, Zeng Cheng was full of respect for this strong man of a different civilization who he had never met, not only did he not destroy this small planet, but also left him a great opportunity.

Suppressing the thoughts in his heart, Zeng Cheng stepped forward quickly, first picked up a top-grade spirit stone casually, and then selected some other grade spirit stones, and then left the Baicao House and walked out of the Baicao Space.

To arrange this mixed element qi array, more than one spirit stone is needed. Zeng Cheng chose a top-grade spirit stone, but it was used to suppress the array eye.

Returning to his bedroom from the Baicao Space, Zeng Cheng put the spirit stone he took out into a basket prepared in advance. Don't look at these spirit stones are only the size of a fist, and their weight is not light. The spirit stones that Zeng Cheng took out included one top-grade spirit stone, and the rest of the upper, middle and lower grade spirit stones were four each, a total of thirteen, but according to Zeng Cheng's estimate, the total weight would not be less than fifty kilograms.

Zeng Cheng went out to see that the light in his parents' simple room had been extinguished, and it seemed that he should be sleeping, so he went out with a basket and came to the spring.

Zeng Cheng didn't start arranging the formation right away, because even arranging the simplest mixed element formation was a very difficult thing for him now. He has to adjust his condition to the best and grasp it to the maximum.

Running the Qi Technique, the True Qi was running slowly in the body, and when he completed the operation of a big week, Zeng Cheng opened his eyes. At this time, his spirit reached its peak.

The next moment, Zeng Cheng began to set up the formation.

Zeng Cheng used his true qi with all his might, and used his divine sense to pull the spirit stone in the basket and beat it into the ground.

The first to be driven into the ground were four lower grade spirit stones, and the place where they were driven into the ground was about three meters away from the spring, roughly in the shape of a square.

Then there were four medium-grade spirit stones, which were still driven into the ground in a square position, but they were staggered by an angle of thirty degrees from the previous four lower-grade spirit stones, and the distance from the spring was about two meters.

Next, Zeng Cheng once again drove the four high-grade spirit stones into the ground, they were still square, and the direction was staggered by thirty degrees from the low-grade and middle-grade spirit stones, and the distance from the spring was one meter.

Then it was time for the most critical time, that is, to beat the best spirit stone into the ground and suppress the array eye.

It's just that Zeng Cheng already felt a little struggling at this time. He was sweating profusely, as if he had been fished out of water. Moreover, he felt that his brain was already feeling a little dizzy, which was a sign of overuse of his divine sense.

However, he couldn't stop, because stopping at this time would mean that all the previous efforts would be wasted, and the twelve spirit stones that were driven into the ground would explode in an instant, including himself, and the family's lives would be over.

Zeng Cheng bit the tip of his tongue hard, and with the instant sobriety brought by the stimulation of his body, he tried his best to use his true qi and smashed that superb spirit stone into the eye of the entire formation.

The next moment, Zeng Cheng fell by the spring, and the whole person collapsed, not wanting to move.

However, Zeng Cheng's heart was happy, because this lowest-level spirit gathering array had been successfully arranged by him. He even felt the strong aura of the newly gushing water in the spring. Stimulated by the aura, the 36,000 pores on his body seemed to be stretched, and he breathed in the aura emitted hungrily.

Moreover, Zeng Cheng also felt that he seemed to have touched a breakthrough barrier. Since he had cultivated the Qi Cultivation Technique, he had never had this feeling of breaking through, so during this period of time, he had been in the early stage of the first level of Qi cultivation, and he had not been able to break through to the middle stage for a long time.

Now this feeling makes him very happy.

It's really a double happiness, he not only successfully set up a mixed yuan array, so that his family can always enjoy the spring water full of aura, so that his business has the greatest guarantee, but also successfully touched the barrier that broke through to the middle of the first layer of qi training.

The opportunity was rare, Zeng Cheng immediately sat cross-legged, ran the Qi Technique with all his might, and entered the cultivation realm of forgetting both things and me.
