All realms have enabled me to achieve the Great Dao.

These meteorites are extremely pure, with all impurities burned away. Furthermore, they have been transformed by the power of the stars, making them even more potent.

If used to forge a weapon, it could be considered an unparalleled divine weapon. This material could even be used to refine magical artifacts, but Zhou Yongcheng didn't think much of it.

Upon returning to Xianyang, Zhou Yongcheng went to Cui Wenzi's residence.

"senior."

"I have obtained the Heavenly Star. Write down the remaining ingredients for the elixir of immortality, and I will have the First Emperor search for them."

Zhou Yongcheng took out paper and pen and pushed them to Cui Wenzi.

Cui Wenzi took the paper and pen and wrote down all the remaining materials for the elixir of immortality. He then pushed the paper and pen next to Zhou Yongcheng, who didn't even glance at it. He threw the list of materials written by Cui Wenzi into the palace and simultaneously sent a telepathic message to the First Emperor, instructing him to collect more.

The next day, the materials were delivered. Zhou Yongcheng took the materials to Cui Wenzi's residence and took out the Heart of the Stars to remove a lot of powder from it.

Cui Wenzi didn't shy away from Zhou Yongcheng. He took out a cauldron and went to the courtyard to start refining medicine.

After watching for a while, Zhou Yongcheng realized that Cui Wenzi's actions were not alchemy at all, but rather medicine making.

After some time, Cui Wenzi used up all the materials and refined thirty-six elixirs of immortality.

"This thing doesn't seem to grant true immortality," Zhou Yongcheng said, examining a pill.

"My knowledge is limited, and I am unaware of the secrets involved. I would be grateful if you could enlighten me, senior."

"Everything in the universe has its limits and cannot remain unchanged forever. Even the world is like this; there will come a day when it returns to chaos. The same is true for the elixir of immortality. The real active ingredient in the pills you refine is the celestial powder. The other ingredients only lock in the energy. After a person takes the pills, they will disperse throughout the body, thus maintaining the body's stability and preventing aging. However, if the energy is completely depleted one day, the person will die."

There was another hidden danger that Zhou Yongcheng didn't mention. If the celestial star shattered, as the energy inside the celestial star dissipated, the energy in their bodies would be attracted by the dissipating energy of the celestial star and thus dissipate as well. However, since the celestial star was taken away by Zhou Yongcheng, this hidden danger was resolved.

"How many years can one pill keep someone alive?" Cui Wenzi asked.

"It can only last for about ten thousand years at most. After that, the energy inside will be completely exhausted."

"Thank you, senior, for informing me."

"How many pills do you want?" Zhou Yongcheng asked.

"Will eating two pills allow me to live for 20,000 years?" Cui Wenzi asked.

"It's useless. One pill or two pills make no difference. The pill takes effect from the moment you make it, and it has a shelf life of ten thousand years. That is to say, the pill will be useless after ten thousand years, and the energy inside will be completely destroyed."

"I'll just take one; there's no point in taking more."

Cui Wenzi took a pill and swallowed it directly. As soon as he swallowed the pill, Zhou Yongcheng saw Cui Wenzi's body emit a white light, which was the light emitted by the power of stars. Then, the light merged into all parts of Cui Wenzi's body, and the elixir of immortality began to take effect, which could keep Cui Wenzi's body unchanged for ten thousand years.

"Do you feel anything?" Zhou Yongcheng asked.

"I don't feel anything, my body hasn't changed, and my cultivation level hasn't increased. It seems that the elixir of immortality can only keep the body unchanged."

"What, you still want to use it to increase your cultivation level?"

"That's the idea," Cui Wenzi chuckled.

"If your cultivation reaches the Nascent Soul Realm, you can absorb the energy from the elixir of immortality, but by then, that energy will have no effect on you."

"Senior, what are the different realms of cultivation?"

"What realms are included in the inheritance you received? After all, I come from another world, so my cultivation realms may be different from the inheritance you received."

"The inheritance I received was incomplete, with only three realms: Qi Refining, Foundation Establishment, and Golden Core."

“That’s about right.” Zhou Yongcheng then explained the different levels of cultivation to Cui Wenzi.

After chatting with Zhou Yongcheng for a while, Cui Wenzi took his leave. He had achieved his purpose in coming to Xianyang. He had ten thousand years, and he didn't know if he could cultivate to the Golden Core Realm. The spiritual energy in this world was slowly fading, and he was afraid it would be a bit too difficult.

Zhou Yongcheng suggested to Cui Wenzi that with his cultivation and medical skills, he could serve the First Emperor.

Cui Wenzi said he didn't like the imperial court, and Zhou Yongcheng didn't say much. Everyone has their own personality, and you can't force them.

Zhou Yongcheng gave Cui Wenzi a medical cultivation technique, a basic storage ring, and a lot of spirit stones. He mainly did this because he saw that Cui Wenzi possessed merit, and people with merit deserve to be helped.

Cui Wenzi bowed deeply to Zhou Yongcheng, expressing his gratitude for Zhou's guidance, and then left.

Zhou Yongcheng returned to his mansion with the elixir of immortality. He had already obtained the Heavenly Star from the mythical world, so there was no need for him to remain in this world.

Upon arriving at the palace, Zhou Yongcheng gave the First Emperor twenty-eight elixirs of immortality, along with the meteorite iron, and then bid him farewell.

Before leaving, Zhou Yongcheng told the First Emperor about Yi Xiaochuan's background, as well as Gao Yao's background, but he didn't know how the First Emperor would treat the two of them.

As for Gao Yao, the First Emperor probably won't care about him, since Gao Yao was brought to Xianyang by Zhou Yongcheng. It's just unknown how Yi Xiaochuan will be treated.

Zhou Yongcheng gave three of the remaining pills to Lü Gong, two to Gao Yao, and then gave the remaining two to Lü Gong after some thought, as he had no use for them.

Having given away all the elixir of immortality, and with that, the world was essentially over. Zhou Yongcheng then took Lü Su and bid farewell to Lü Gong and the others before returning to the real world.

In the Xianyang Palace, the First Emperor summoned Yi Xiaochuan.

"I have met your Majesty."

"Meng Yi, Yi Xiaochuan, can you tell me your true origins?" the First Emperor asked, posing a soul-searching question.

Yi Xiaochuan's heart skipped a beat. Why would the First Emperor ask such a question? Did he sense something?

"Your Majesty, I am a member of the Meng family. I was separated from my family in my childhood and only returned to my clan last year," Yi Xiaochuan replied, forcing himself to speak.

"Do you know what crime it is to deceive the emperor? Gao Yao has told you everything." The First Emperor's lips curled up slightly.

Yi Xiaochuan inwardly cursed Gao Yao as a swindler. He had only been in Xianyang for a short time when he found Gao Yao in the restaurant he owned. He learned about Gao Yao's experiences over the years from Gao Yao, but he found that Gao Yao was not as familiar with him as before, and there was a deep estrangement between them.

All of this was because of Zhou Yongcheng. When Zhou Yongcheng had nothing better to do, he told Gao Yao about his fate, saying that if he hadn't met him, Gao Yao would have been tricked by Yi Xiaochuan into becoming a eunuch in the palace, and so on. Gao Yao believed Zhou Yongcheng's words without question, so he developed a bit of a dislike for Yi Xiaochuan.

"Your Majesty, please ask whatever you wish to know. I will answer everything I know." Yi Xiaochuan had no other choice but to save his life. There was a beautiful girl waiting for him at home, and he couldn't afford to die.

"Where are you from?"

"The world more than two thousand years from now."

"If I hadn't asked you, would you not have revealed that you came from the future, and would you have watched helplessly as the Qin Dynasty perished and was replaced by the Han Dynasty, and would you have joined the Han Dynasty?" the First Emperor asked in an icy tone.

Yi Xiaochuan was drenched in sweat, beads of sweat forming on his forehead. The First Emperor actually knew about the Han Dynasty? Gaoyao didn't seem to have such a high level of culture.

"Your Majesty, minister..."

"You are not my subject, and I cannot afford to use a subject like you. Go back; I do not want to see you."

After Zhou Yongcheng revealed Yi Xiaochuan's background and combined it with his knowledge of Yi Xiaochuan's actions in the Qin Dynasty, he saw through Yi Xiaochuan and concluded that this person was not capable of great things and was only suitable to be an ordinary commoner.

After that, Yi Xiaochuan withdrew from the Qin Dynasty's political arena and went into business.
