"If we don’t resist, when Blue Star is swallowed by the Void Demon Realm, our entire Human Race will be relegated to a lower class, becoming nothing more than slaves, toys, and pets to the powerful Void Demon clans."

"If we can produce a few Divine-level Powerhouses, then even if our world is swallowed by the Void Demon Realm, the Human Race can still secure a place for itself there. We won’t be completely at their mercy."

"Furthermore, while the Void Demon Realm is vast and resource-rich, the competition is also incredibly fierce. All those abundant resources already have owners. If we want to advance to the Divine Spirit rank, our only option is to fight the Void Demons and contend for the world’s resources."

"Ascending to the Divine Spirit realm is not so simple!"

The Four Extremes Spirit Saint Wu Zhongchao let out a soft sigh. Although he had already advanced to the Spirit Saint Level in four different worlds, earning him the title "Four Extremes Spirit Saint," and his combat prowess could even rival a Demigod-level powerhouse, he still felt that ascending to the Divine Spirit realm was fraught with difficulty.

Shu Feng became pensive.

Wu Zhongchao smiled faintly. "I came this time to tell you that I’ve already found your other self in the Black Tortoise Realm. As long as you go over and replace him, you’ll be able to integrate seamlessly into that world."

Shu Feng frowned slightly. "Do I have to kill him?"

"Killing him is one way. Ordinary Void Demons are just that simple and crude. They kill their other selves to absorb everything from them and evolve."

"However, the best method is fusion and absorption. You use a Secret Technique to merge with his soul, fulfill his dying wish, and absorb his soul and Life Essence. This will allow you to undergo a metamorphosis on a fundamental level."

"Some of the top figures in the Void Demon Realm evolve this way. It’s said that Gulondo World was able to defeat the Void Demon Realm’s invasion because one of their top figures descended upon Gulondo World. It was all a grand scheme for him to devour his own soul in that world."

"This method is considered a top secret in the Void Demon Realm. Only a few Divine Spirit-level figures use it. I myself was able to become the Four Extremes Spirit Saint by using this Secret Technique."

Wu Zhongchao smiled faintly, his eyes landing on Shu Feng.

Shu Feng’s eyes lit up. "Sir, I ask that you teach me this Secret Technique! If I become a Divine-level Powerhouse in the future, I will certainly come back and help you ascend to the Divine Spirit realm!"

"Very well. I hope you remember the promise you made today."

Wu Zhongchao gave a faint smile. With a spread of his fingers, a blue crystal materialized and floated steadily toward Shu Feng.

This was a knowledge crystal from Gulondo World. It could only be used once and contained all the knowledge infused into it by its creator.

Shu Feng crushed the blue crystal in his grip, and the text of a profound and mysterious Secret Technique instantly flooded his mind.

"Thank you, Sir, for bestowing this Secret Technique upon me!"

When Shu Feng perceived the profound and mysterious Secret Technique, his eyes lit up, and he gave Wu Zhongchao a deep, formal bow.

Wu Zhongchao waved his hand dismissively. "All right, you may go."

Shu Feng smiled. "Yes, Sir!"

In the days that followed, Shu Feng left the Mire Dragon Territory in the care of Li Xuan Yi and Zhu Chenyu. He then announced that he was entering secluded cultivation and vanished from public view.

「Erosion Realm, Xuanlei City.」

This city was controlled by the Blue Star Human Clan and was the closest city to the Black Tortoise Realm.

’So this is Xuanlei City, the only city that trades with the Black Tortoise Realm! It really is bustling!’

As Shu Feng walked through Xuanlei City, he saw a mix of people on the streets: some were dressed in the style of a wuxia world, while others wore modern, fashionable clothing.

Xuanlei City was the closest city connecting the Blue Star Realm and the Black Tortoise Realm. Many specialty goods from both the Black Tortoise Realm and Blue Star were traded here, making the city exceptionally prosperous.

Shu Feng had already used the Hundred-Night Illusion Transformation, one of the Nine Great Divine Techniques of the Prison Skull Sect, to alter his appearance. He was preparing to infiltrate the Black Tortoise Realm through Xuanlei City and find his other self.

Both the Fang Clan and the Zhu Clan had their own factions within the Black Tortoise Realm. But Shu Feng had made countless enemies and had no intention of letting them know his whereabouts.

Shu Feng was now a Spirit Venerable Realm powerhouse with combat strength comparable to a Half-Saint. He needed to prepare for a direct breakthrough to the Spirit Saint realm. His goal was to acquire the top Secret Techniques within the Black Tortoise Realm.

The Hao Wei Escort Agency was one of the ten largest escort agencies in Xuanlei City, specializing in transporting goods and escorting people between the Black Tortoise Realm and Xuanlei City.

"Welcome. How may I help you?"

The moment Shu Feng stepped into the Hao Wei Escort Agency, a lovely woman in a blue dress approached him, her face bearing a professional smile.

Shu Feng said, "I need an escort to the Black Tortoise Realm."

The lovely woman smiled faintly. "May I ask if you have any enemies in pursuit? If so, please state their level of strength. If you lie about this, our agency reserves the right to hand you over should we encounter danger."

Shu Feng replied coolly, "I have no enemies. If we run into any, you can hand me over."

The woman in blue said, "Understood. Do you wish to travel with the main caravan or opt for a private, customized escort? Traveling with the main caravan to the Black Tortoise Realm costs 3,000 Gold Coins, or 300 million Qianyuan. A private escort costs 300,000 Gold Coins, or 30 billion Qianyuan."

’Travel in the Otherworld is just this expensive, with costs easily reaching the hundreds of millions. If you don’t hire a major agency like the Hao Wei Escort Agency, you’re bound to run into all sorts of danger on the road.’

Shu Feng said, "I’ll go with the main caravan."

’Although the main caravans are large, their defensive power is also far greater than a private escort’s. Besides, if something really goes wrong on the road, the others can serve as cannon fodder, buying me more time to respond.’

The woman in blue handed him a contract. "Here is the contract. Please look it over. If there are no issues, you can sign it and then submit payment."

Shu Feng took the contract, glanced over it, and saw no issues. He promptly signed a fake name and handed over a bank card. "I’d like to leave for the Black Tortoise Realm as soon as possible."

The woman in blue handed Shu Feng an identification token. "Be at the city gate at 8 AM tomorrow. A large caravan is preparing to depart for the Black Tortoise Realm. This is your identification token. Please keep it safe!"

Shu Feng turned and left.

「The next morning, at 8:00 AM.」

When Shu Feng arrived at the gates of Xuanlei City, a massive caravan of about three hundred people came into view.

Although the Hao Wei Escort Agency was an escort agency by name, it was also heavily involved in inter-realm trade. They could make a fortune just by selling various specialty goods from Blue Star in the Black Tortoise Realm. Naturally, their escort services were just one part of their business.

’This caravan isn’t weak! It’s actually being guarded by two Spirit Sect Level powerhouses!’

Shu Feng glanced over the caravan, his gaze briefly sweeping past a bearded, world-weary middle-aged man and an elderly, white-haired man.
