After all, it takes a considerable amount of time for the energy in one's body to be released and then replenished.

Although this world does not have a separate energy entity like a spirit model, it possesses a wide variety of materials, most of which can be catalyzed by cultivators using their spiritual power.

Guan Wen had already found out most of these things when he was inquiring about the Divine Ring.

He placed the mold inside the room, then went out to the market to buy refining materials.

In this world of cultivation, the materials for crafting divine rings are not purchased from designated malls like in the world of supernatural abilities. There are many shops selling divine rings in this market, and many cultivators frequently visit these shops, so these places are not monitored.

Guan Wen randomly picked a shop that sold refining materials and went inside. As soon as he pushed open the door, he saw a lot of cultivators looking around inside, and the shop assistants and the owner were busy serving customers.

Upon seeing this, Guan Wen began to look around on his own, and soon noticed several materials on the shelf that looked quite good.

Just then, the owner, who had finished serving the other guests, hurried over to Guan Wen and asked, "Sir, is there anything you've taken a fancy to?"

"What's that?" Guan Wen pointed to a transparent box on the shelf that emitted a pale blue light. The light emanating from it was clearly released by the powder inside.

"Sir, you have excellent taste." Upon seeing this, the shop owner immediately stepped forward, took the transparent box from the shelf, and placed it on the counter in front of Guan Wen, saying, "This is a second-grade divine ring refining material, Magic Light Powder. It's an excellent material for refining divine rings. Besides providing a considerable amount of spiritual energy, during the refining process, you can first construct the shape of the divine ring, and then sprinkle this powder on the outline of the construction. This powder will automatically absorb the spiritual energy you release, making it quite useful."

The people in this world call all energy spiritual energy and spiritual power. Although the terminology has changed, Guan Wen found it familiar and nodded slowly.

According to the shop owner, the material used to refine this so-called Magic Light Powder is indeed quite good. After all, this kind of material is used to replace the energy in one's own body, and it is not expected to do much more. However, this Magic Light Powder can be absorbed by spiritual power, that is, energy, thereby playing a role in some layered structure and form structure, which is quite important to him.

So he nodded and said, "That's right. In that case, how much does this magic powder cost?"

"Fifty mid-grade spirit stones per box."

"Okay, in that case, give me a hundred boxes!"

"What! One hundred boxes!" Upon hearing Guan Wen's words, the shop owner's eyes widened in surprise. Although he had served at least eight hundred to a thousand cultivators since he opened his shop, he had never seen a cultivator as generous as Guan Wen, who actually asked for one hundred boxes of magic light powder.

After the initial surprise, a look of wild joy immediately appeared on his face. He quickly instructed the other shop assistants to bring out all the remaining eye powder from the store. At the same time, his smile became even wider as he hurriedly invited Guan Wen to sit down and served him a cup of spiritual tea.

This spiritual tea is a vibrant green color, emanating an aura of spiritual energy. It is a beverage highly favored by cultivators in this world, and it is quite expensive. Ordinary cultivators are reluctant to drink it on ordinary days, only bringing it out to entertain guests.

Guan Wen took a sip of spiritual tea. The spiritual energy dissipated quickly as soon as it entered his mouth. Spiritual energy is a rather complex aggregate of energies, but he only possesses time-based and fire-based abilities. Furthermore, these abilities do not exist simultaneously; they need to be switched. Therefore, this kind of spiritual energy is completely useless to him.

So after taking a few sips, he stopped touching the cup of spiritual tea.

Soon, the shop assistants placed one hundred boxes of Magic Powder in front of Guan Wen, stacking them up like a small mountain.

After Guan Wen paid the spirit stones, the shopkeeper looked at him with a big smile, thinking that he would wave his hand and put all these things into the Sumeru Ring.

But after waiting for a long time without Guan Wen making a move, Guan Wen simply threw the boxes of magic powder into his pocket, slung them over his shoulder, and walked out, leaving the boss behind him dumbfounded.

It's strange that such a wealthy cultivator doesn't use a Sumeru Ring!

After Guan Wen returned the refining materials to the inn, he went to the market again. This time, he wanted to buy a star chart and wooden rails.

The astrolabe is what is called the celestial disc in the world of supernatural abilities. The celestial disc is a disc machine that can be inverted onto a mold and injected with energy, and then automatically constructed.

This is much more convenient than constructing them one by one by hand. However, there are obviously drawbacks to using this kind of celestial plate. After all, a machine is a machine. It cannot replace human labor. In many details, it cannot achieve the same level of creativity and attention to detail as humans.

After all, the Tianwu Ring is a three-dimensional structure. No matter how precise a human machine is, it is impossible to consider every detail of a three-dimensional structure, because the human body is the most precise machine for perceiving the three-dimensional world.

The natal chart is similar to the celestial chart, but it is more primitive and cannot be automatically constructed. However, the divination tool can perform a simple semi-automatic construction based on the natal chart. In other words, the divination tool can manipulate the other party to construct the chart, which is much more efficient than constructing it directly.
