All realms have enabled me to achieve the Great Dao.

"Sir, you have come to my Sui Dynasty and shown me the changes that followed. You must also want to change the fate of the Sui Dynasty. Now that I know my own destiny, I will not let it repeat itself. The Sui Dynasty will not perish in my hands, Yang Guang." Yang Guang said firmly.

Zhou Yongcheng said nothing and led Yang Guang back to his office.

Yang Guang looked at the familiar surroundings; he was back again.

"Sir, you can come to me for anything in the future. I will do my best to help you with anything I can." Yang Guang clasped his hands in a salute to Zhou Yongcheng.

"Nothing else, I just took a liking to the books in your office."

"Please feel free to take it, sir." Although Yang Guang was somewhat reluctant, he still generously gave it to Zhou Yongcheng.

Zhou Yongcheng chuckled and unceremoniously took away all the books from the surrounding study rooms, leaving only empty rooms.

"I've taken your books, but I'll give you some gifts in return. I have some martial arts manuals here that you can use to train your subordinates. One of them is the Sunflower Manual that eunuchs can practice."

Zhou Yongcheng used his divine sense to enter the storage space, took out a martial arts manual, and placed it on Yang Guang's desk.

Yang Guang walked to his desk, picked up the secret manuals, and began to read them. Some of the manuals were profound, while others were ordinary.

Zhou Yongcheng then said, "I see that you have already cultivated to the late stage of the Acquired Realm, but your body is somewhat lacking. I will give you some meat from other worlds to strengthen your body."

Zhou Yongcheng took out a large piece of giant beast meat and placed it on the ground; it looked to be over a ton.

"Thank you sir."

"You're welcome, let's exchange."

"I go first."

Zhou Yongcheng glanced at the eunuch lying on the ground, withdrew the magic from the eunuch, and the eunuch immediately woke up. Then Zhou Yongcheng disappeared.

Seeing Zhou Yongcheng disappear, Yang Guang became convinced that Zhou Yongcheng was an immortal. Even the three grandmasters could not disappear into thin air.

The eunuch immediately knelt down upon waking, "Your Majesty."

"Get up. Have someone take this piece of meat away. No one is allowed to steal a bite of this meat. If I find out that even a tiny bit of meat is missing, the entire family will be exterminated."

The eunuch's heart skipped a beat, realizing the importance of this piece of meat.

As Yang Guang sat in his chair, he pondered the scenes he had witnessed. He hadn't expected so many people to rise up against the Sui Dynasty. From the scenes, he realized that he himself had caused it all. He had abused the people's labor, launched wars without allowing the people to recover, and he had also seen that in his later years, Yang Guang had become extravagant and imposed excessive taxes. These were all reasons for the downfall of the Sui Dynasty.

Yang Guang was very fortunate that his son had arrived early; if he had arrived a few years later, he would probably have been beyond saving.

Now that we know the trajectory of future developments, we need to carefully consider what to do.

Zhou Yongcheng arrived in an unknown world, collected the items from the cave, and began searching for a place to cultivate.

After a day of searching, they found a decent cave on the other side of the lake. Inside the cave was a giant beast, the appearance of which Zhou Yongcheng had never seen in the real world, so he killed it on the spot.

Zhou Yongcheng carefully examined the cave. Inside, there were some spirit jades, which were excellent materials for carving talismans, more than ten times better than talisman paper.

In the days that followed, Zhou Yongcheng began to study supernatural powers and techniques. The first thing he studied was teleportation. He had used the Five Elements Escape Technique before, but although it was good, it was not as fast as teleportation.

After meditating for several days, Zhou Yongcheng used teleportation to arrive at the lakeside. Teleportation is great; as long as one's divine sense can reach a place, one can arrive instantly. If one is bold enough, one can also use all one's magical power to teleport at will. However, the location is uncertain, and there may be unexpected surprises at the destination.

Therefore, one's spiritual power and cultivation level determine the distance of teleportation.

Several robots stood motionless beside the machine, and the room was filled with weed powder.

Zhou Yongcheng cleared the weed powder from the room and came to the real world. He disappeared directly from the room and went to the warehouse, where he piled all the weed powder in the warehouse.

Standing inside the warehouse, Zhou Yongcheng looked at the weed powder inside. He couldn't keep an eye on this stuff every day; someone had to manage it. After thinking for a while, he decided to automate the warehouse and hand it over to Hong Houhou for management.

Without hesitation, Zhou Yongcheng contacted the automatic door vendor and asked them to bring over a set of equipment to modify the warehouse door, handing over control to Honghou.

If the feed mill in town runs out of raw materials, Honghou can simply place an order online and have a driver come and pick them up. She also has the loading person's phone number, so Honghou can contact them directly. Perfect.

Zhou Yongcheng spent most of the day converting the warehouse into a smart control system. He also installed several high-tech cameras inside the warehouse, allowing the Queen to observe the situation inside and outside the warehouse through the cameras.

With everything settled, he no longer needed to worry about the feed ingredients.

Zhou Yongcheng arrived in the Sui Dynasty and appeared in Yang Guang's office. The office was empty at the time. He scanned it with his divine sense and saw that Yang Guang was in a meeting.

He disappeared from Yang Guang's office and arrived above Cihang Jingzhai.

He didn't know if the He Shi Bi was at Cihang Jingzhai at this time. He scanned Cihang Jingzhai with his divine sense but didn't see what he wanted. However, he did see the Cihang Sword Manual and put it away without any hesitation.

Since the He Shi Bi jade was not at Cihang Jingzhai, it was likely at Jingnian Zen Temple, so he appeared in the sky above Jingnian Zen Temple.

The He Shi Bi jade contains mysterious energy that can enhance a person's spirit, but it's unknown whether it can enhance a person's primordial spirit. Zhou Yongcheng wants to take a look.

Zhou Yongcheng scanned the Jingnian Temple with his divine sense and saw the He Shi Bi jade placed in a bronze hall.

He used his divine sense to take the He Shi Bi jade directly, and examined it in his hand from the air.

There is indeed a mysterious energy inside the He Shi Bi jade, but it is unknown whether it can be absorbed.

Zhou Yongcheng arrived at an unknown world, a place for cultivation.

He began to absorb the mysterious energy within by circulating the Heavenly Origin Technique. After entering Zhou Yongcheng's body, the mysterious energy went straight to his Purple Mansion and was used entirely to enhance his primordial spirit.

In no time, the mysterious energy within the He Shi Bi was completely absorbed, causing Zhou Yongcheng's primordial spirit to double in strength.

After completing his cultivation, Zhou Yongcheng looked at the He Shi Bi jade in his hand, which no longer contained any mysterious energy.

He felt it was a bit of a pity that there was too little mysterious energy inside.

What Zhou Yongcheng didn't know was that the energy inside the He Shi Bi had accumulated for hundreds of years, and now he had absorbed it all.

They arrived in the Sui Dynasty, and Zhou Yongcheng went to Yang Guang's office.

Yang Guang was working, and the eunuch next to him was the same one as before.

"Your Majesty, the master has arrived," the eunuch reminded Yang Guang.

Yang Guang looked up and saw Zhou Yongcheng. He stood up happily and led Zhou Yongcheng to the room next door.

"Sir, you have come at just the right time. I have some questions I would like to ask you," Yang Guang said respectfully.

At this moment, the eunuch poured Zhou Yongcheng a bowl of tea.

Zhou Yongcheng picked up the bowl and looked at the tea soup, but had no desire to drink it. Was this tea? It was probably more like tea porridge.

Setting down his teacup, Zhou Yongcheng said, "Go ahead and speak."

"After careful consideration, although I have discovered that I was responsible for the downfall of the Sui Dynasty, I have also found that there were many behind-the-scenes manipulators, namely those powerful clans. Although some members of those powerful clans hold official positions in the court, they are not working for the Sui Dynasty, but for the development of their own families. May I ask, sir, how can we weaken the power of those powerful clans?"
