All realms have enabled me to achieve the Great Dao.

In the unknown world, Zhou Yongcheng was overjoyed to see the robot dig up so many spirit stones again.

He arrived at a cave, took out a high-grade spirit-gathering array plate, placed a top-grade spirit stone on the plate, and then pointed at the plate with his finger. The array plate was activated, and the spirit-gathering array spread out. Zhou Yongcheng adjusted the array plate to reduce the range of the spirit-gathering array until it only covered the cave where he was.

The concentration of spiritual energy within the area covered by the Spirit Gathering Array was increasing rapidly. Zhou Yongcheng sat cross-legged in the middle of the array and took out all the top-grade spiritual artifacts he had purchased to begin refining them.

Two or three months passed in the cultivation world. Zhou Yongcheng refined everything and put the Daoist robe directly on his body. He wouldn't need to change his clothes anymore.

The bell can be stored inside the body for defense.

As for other items, store them in the storage space and take them out when needed.

In these two months, not only have I refined all the equipment, but I have also raised my cultivation level to the mid-stage of the Refining Spirit Returning to Emptiness Realm. This is all thanks to the Spirit Gathering Array. This thing is really good.

After finishing their training, the robot reported something to Zhou Yongcheng: they had dug a cave in a certain place, and there was a pool of water inside the cave.

Upon hearing this, Zhou Yongcheng scanned the area with his divine sense and instantly disappeared from his original spot, arriving at the pool the robot had mentioned.

"Spiritual liquid, top-grade spiritual liquid. This stuff is even more advanced than top-grade spirit stones. With this, cultivation will be much faster."

Zhou Yongcheng burst into laughter, feeling his luck had finally turned around.

Zhou Yongcheng searched for containers, but there were none in his space. This wouldn't do. Zhou Yongcheng went to the cultivation world and bought several top-grade spiritual artifact containers from the Treasure Pavilion. The containers were originally used to hold pills, but Zhou Yongcheng used them to hold spiritual liquids. As long as he could hold something, it didn't matter what he put in them. Zhou Yongcheng didn't care about those things.

The spiritual liquid in the cave was only a little over two cubic meters, and each container was only half full.

"You should dig outwards from this center."

"Yes, Master."

Zhou Yongcheng returned to the real world, where it was late at night. He checked the time and realized it was almost May.

After looking at this two-story building, it's time to eliminate it.

Zhou Yongcheng put everything on the second floor into his spatial storage, flew out of the small building, and with a thought, put the small building back into his spatial storage.

Zhou Yongcheng took out the six-story building he had purchased from the cultivation world. With a thought, the building in his hand slowly grew larger. He threw it back to the original location of the building, and it became the same two-story ancient building that sat in the original spot.

The exterior of the building remained unchanged, looking exactly the same as before, but the interior space was completely different. Only two floors of the interior were visible, while the other four floors were hidden. Only Zhou Yongcheng could go up to the top, and no one else could see them.

Upon arriving on the second floor, he took out all the bookshelves in the space and rearranged them according to his own preferences.

The space is now dozens of times larger than before, and it's not as crowded as it used to be.

There are no lights on the second floor right now, and the power lines connecting the two corridors to the building are disconnected. The lines will be reconnected tomorrow, so the building won't need any lights; we'll use the lights from the cultivation world for illumination.

After arranging all this, Zhou Yongcheng arrived in the world of Iron Man.

Inside Tony's lab, Zhou Yongcheng noticed that Tony didn't seem to be studying his Iron Man suit, but rather something else.

Jarvis told Tony about Zhou Yongcheng's arrival.

"Zhou, it's been a long time."

"Long time no see, what are you researching?"

"I'm researching body enhancement. Ever since I started practicing the techniques you taught me, I've felt that researching the Iron Man suit doesn't give me a sense of security, and the Iron Man suit can't increase my lifespan or anyone else's. So I'm researching methods to enhance the human body."

This Iron Man has turned out awful.

However, Zhou Yongcheng felt that his research on human enhancement methods was better than his research on Iron Man suits. After all, Iron Man suits are ultimately external objects, while true strength lies in one's own physical power. If the two were combined, it would be even more perfect.

"Any results have been achieved?"

"The first generation of human enhancement drugs has been developed, and it's not bad. After ordinary people use human enhancement drugs, their strength can be comparable to that of special forces soldiers, and special forces soldiers are even stronger when they use them."

"That's not bad. How's the second-generation research going?"

"The formula is still being improved, and it won't be long before it's developed."

"You're a genius. Have you ever used any human enhancement drugs yourself?"

"It's useless to me. It might be because I've been practicing a technique that has already strengthened my body. If I want my body to be strengthened, I might need to use a fourth-generation, fifth-generation, or even sixth-generation enhancement potion. It's hard to say. We'll only know after we research and use it."

Zhou Yongcheng nodded. "Decades ago, a man named Erskine developed a drug called the Super Soldier Serum. He used it on Steve, which enhanced Steve's body. Now, compared to Steve, can you beat him without using the Iron Man suit?"

“No, his strength is immense, reaching ten or twenty tons. Even without the Iron Man suit, he only has a strength of a few tons,” Tony said.

Has the formula for the Super Soldier Serum been passed down to us?

"No, but I have Steve's blood. I'm researching it. His blood has given me a lot of information. I believe I can develop a human enhancement drug that is even more powerful than Erskine."

“You will succeed because Erskineer’s super soldier serum is only usable by a very small number of people, while the human enhancement drug you developed can be used by anyone. You are better than him,” Zhou Yongcheng said with a smile.

"Zhou, thank you." Tony hugged Zhou Yongcheng.

"You're welcome. I'll also use what you've researched."

"Zhou, you're already this strong, why would you need the enhancement potion I developed?" Tony didn't believe Zhou Yongcheng's words at all.

Zhou Yongcheng smiled and said, "Tony, you have to consider that I will go to many worlds. Not everyone in every world is a strong person. Most people in many worlds are ordinary people, and they cannot cultivate to become stronger. So I will trade your human enhancement serum for you to use in other worlds."

"Zhou, you are a great philanthropist."

Zhou Yongcheng smiled but didn't say anything. A good person? He killed a lot of ordinary people.

Zhou Yongcheng took out a low-grade spiritual artifact-level storage ring and handed it to Tony, saying, "This is a spatial ring. You only need to drip a drop of blood on it to use it."

Tony took the ring and examined it in his hand. Such a small thing was a spatial treasure, an Eastern magic trick, it was truly amazing.

He pricked his finger with a needle and dripped a drop of blood onto the ring. Instantly, Tony felt a subtle connection between himself and the ring.

"If you use your mind to sense the ring, you will find a space, which is the storage space where the ring is located."

Tony had cultivated internal energy, and now possessed substantial spiritual power. He sensed a large space, at least a hundred cubic meters in size.

Zhou Yongcheng then taught Tony how to use the storage ring. After learning how, Tony put the things in his laboratory into the storage space, and then took them out and put them away again, having a great time.

Watching Tony having fun, Zhou Yongcheng thought of when he first got the cheat code. He felt the same way. After all, such a magical thing was always very strange when you saw it for the first time.

Zhou Yongcheng bid farewell to Tony, not wanting to disturb his research on the human enhancement drug. Before leaving, Zhou Yongcheng said he would come back in a while to pick up the formula for the human enhancement drug.
