All realms have enabled me to achieve the Great Dao.

Seeing that the mining of spirit stones was progressing slowly, Zhou Yongcheng took out several thousand more robots and had them join the army of spirit stone miners.

The spiritual energy deep inside the mine is very dense. I can't even imagine how dense the spiritual energy would be if I dug into the center of a spirit stone vein.

Zhou Yongcheng found a spot and began his cultivation.

For the next two weeks, Zhou Yongcheng spent his time cultivating. Since reaching the Refining Spirit and Returning to Emptiness realm, he felt that his cultivation progress had slowed down by at least a hundred times. To this day, he was still stuck in the early stage of the Refining Spirit and Returning to Emptiness realm.

Keep in mind that he absorbed an entire Mind Stone from the Marvel universe, yet he didn't even break through a minor realm, which shows just how difficult cultivation is.

If he hadn't felt his primordial spirit and magical power slowly increasing, he would have started to suspect that there was something wrong with his body.

Half a month later, the hundreds of robots finally dug up a top-grade spirit stone. He had thought that this spirit stone mine didn't have any top-grade spirit stones.

A few more days passed, and the robot mined hundreds of thousands of top-grade spirit stones, millions of high-grade spirit stones, tens of millions of mid-grade spirit stones, and billions of low-grade spirit stones.

Now Zhou Yongcheng felt confident again, so he didn't take the robots back and let them continue digging.

Upon arriving in the City of Freedom, Zhou Yongcheng entered the Treasure Pavilion.

He went straight to the third floor, where he was greeted by the same beautiful nun.

Zhou Yongcheng asked with a smile, "What's on the fourth floor?"

Since this building has six floors, what are the things on the floors above the fourth floor?

"Senior, the fourth floor contains a quasi-immortal artifact."

"What about the fifth floor?"

There's nothing on the fifth floor.

Zhou Yongcheng nodded. It seemed that the fifth and sixth floors were Baoqige's private premises.

"May I go up to the fourth floor?"

"Sure, but to buy a quasi-immortal artifact, you'll need to use top-grade spirit stones for the transaction," the beautiful saleswoman reminded Zhou Yongcheng.

"How can there be such a rule? Can't we use high-grade spirit stones?"

The saleswoman was somewhat surprised. Didn't this senior colleague know?

"Senior, the number of top-grade spirit stones produced by the spirit stone mines in the cultivation continent is getting smaller and smaller. Therefore, no matter what kind of cultivation resource it is, the higher the grade of the item, the more it can be traded with top-grade spirit stones."

Zhou Yongcheng nodded. In that case, top-grade spirit stones must be very valuable.

"Okay, I'll go upstairs and take a look first, then come back down to buy some things I need."

Zhou Yongcheng went up to the fourth floor.

There were very few things on the fourth floor, and even fewer people, with only an old man guarding the place.

Upon seeing the old man, Zhou Yongcheng sensed danger. The old man's cultivation was very high; he was at least a Void Returning Realm expert.

The old man saw Zhou Yongcheng, but he couldn't see through him. He was a Three Tribulation Loose Immortal, yet he couldn't see through the cultivation level of a young man. Could it be that this person had something on him that was hiding his cultivation level?

Zhou Yongcheng ignored the old man and examined the near-immortal artifacts inside the display case.

The quasi-immortal artifact on the counter is an ancient zither. He doesn't know how to play it, and even if he could afford it, it would be useless to him.

Let's look at the next item. On this display case is a clock, somewhat like the bells that monks used to ring in ancient temples.

This thing is interesting; it can be used for defense or against enemies.

Look at the price, over ten thousand top-grade spirit stones. The price difference is quite large. Top-grade spirit weapons only cost tens of thousands of high-grade spirit stones, while quasi-immortal weapons cost over ten thousand top-grade spirit stones. The difference is not ordinary.

"Old sir, why is there such a huge difference between a quasi-immortal artifact and a top-grade spiritual artifact?" Asking questions when you don't understand is a good habit.

"Because quasi-immortal artifacts are forged by Ninth Tribulation Loose Immortals, some materials do not meet the standards of immortal artifacts, so the immortal artifacts are not forged. However, some materials are between top-grade spiritual materials and immortal-grade materials, so they are called quasi-immortal artifacts. Top-grade spiritual artifacts use top-grade spiritual materials, so the difference in material grade is huge, and the restrictions are even more different, which is why there is such a big difference in price." The old man explained to Zhou Yongcheng very carefully.

Quasi-Immortal level materials? What kind of materials are they? Did they fall from the Immortal Realm?

Zhou Yongcheng then went to look at the other two items: a knife and something that looked like armor.

After inquiring, I learned that the armor-like thing was actually worn on the Nascent Soul to protect it. It was a pity that Zhou Yongcheng did not cultivate the Nascent Soul, otherwise he could have bought it.

There were only four items on the fourth floor, and Zhou Yongcheng only took a liking to the clock.

"Sir, I'll take this clock."

Upon hearing this, a glint of light flashed in the old man's eyes, and he took the clock down from the display case.

Zhou Yongcheng took out more than 100,000 top-grade spirit stones and gave them to the old man. The old man took them, glanced at them, and found that the quantity was correct, so he gave the bell to Zhou Yongcheng.

Zhou Yongcheng took the clock and put it into his storage space. This action startled the old man.

What kind of storage space can hold a quasi-immortal artifact? Only an immortal-level storage space can hold a quasi-immortal artifact. It seems this young man has quite a background.

Upon arriving on the third floor, Zhou Yongcheng wandered around and bought a pill furnace, which could be used to refine pills and craft weapons.

I bought a Taoist robe. The robe can change its appearance at will, even its color.

I bought a flying boat and several storage rings.

He originally wanted to buy a three-story house, but there were no three-story houses available, only six-story and nine-story ones, so he bought a small house instead.

Next to the small building I bought, there were several palace-like houses. When I asked, I found out they were houses that could be transformed at will.

All the items he bought were top-grade spiritual artifacts, which made the beautiful saleswoman very happy.

After finishing his shopping, Zhou Yongcheng went downstairs and bought another batch of low-grade spiritual artifact-level storage rings. When buying the storage rings, he remembered that he had promised Tony that he would help him prepare a space, so he bought some low-level storage rings.

After leaving the Treasure Pavilion, Zhou Yongcheng strolled around Free City. He came to a shop that sold pills and bought a few pills used by cultivators in the Returning Void Realm and Integration Realm. He didn't know if these pills would be useful to him, so he only bought a few.

Instead of buying many pills, Zhou Yongcheng found a shop that specialized in selling array plates and bought a lot of them, including spirit-gathering arrays, killing arrays, trapping arrays, and illusion arrays. These were quite useful.

He then saw a shop selling spirit tea on the street. He was surprised that people in the cultivation world actually drank tea. Zhou Yongcheng looked at the two kinds and took a liking to them. One was the most expensive Gathering Spirit Tea, which was said to enhance the primordial spirit. The other was ordinary spirit tea.

Zhou Yongcheng asked the boss if ordinary people could drink the spiritual tea. The boss said that ordinary people who drink the spiritual tea regularly can not only refresh their minds and strengthen their bodies, but also gradually increase their lifespan.

Zhou Yongcheng neither confirmed nor denied what his boss said. Whether what his boss said was true or not, only after drinking it would one know; his boasting was useless.

Both tea shop owners let Zhou Yongcheng try the tea. It was alright, especially the owner's Spirit Gathering Tea, which could indeed enhance his spiritual energy. Although the ordinary spiritual tea had no effect on Zhou Yongcheng, he could feel the effect of the spiritual tea after tasting it.

Zhou Yongcheng looked at the spirit stones in his storage space. He bought 100 catties of ordinary spirit tea and used the rest to buy Gathering Spirit Tea. He didn't even manage to buy more than a few catties. He would drink this tea from now on and would change it if he came across a better one.

After exhausting his spirit stones, Zhou Yongcheng left the cultivation world.

The spirit stones that so many robots spent so much time mining were all spent by Zhou Yongcheng in less than a day.
