The Swift Walker and the Gun Spirit King are two renowned grandmasters in the Iron Dimension, and their heroic deeds are widely known.

But at some point, he forgot about the Gun Spirit King and only remembered that he had a very good old friend.

He has no peers left, so naturally he has no one to ask for information...

Fortunately, he wasn't the type of person who liked to overthink things.

Time passed uneventfully, and he was exceptionally happy during his cultivation and apprenticeship training... Little did he know that his old friend was using his skin to bully his young apprentice...

Young Xia Xiang had no idea why her kind master, who had been so gentle in the morning, would keep giving her extra lessons in the afternoon for various reasons. She thought that this was how Jiu Wu had been taught.

...

One day later, that familiar figure appeared in his mind, bringing back some things he had forgotten.

Back then, at the height of their confidence, they made a pact to defeat the greatest demon threatening the twelve timelines—Diablo, the Demon Lord.

Their tacit understanding throughout the journey boosted their confidence, leading them to defeat Diablo.

However, they only destroyed Diablo's physical body, while the Gun Spirit King's will was corrupted because he shielded Diablo from harm.

To prevent himself from becoming a demon, the Gun Spirit King abandoned his original body, sealed all his energy and soul within him, erased his memories, and fell into silence.

Then, the Gun Spirit King explained to him everything about Xia Xiang and the Divine Realm...

He knew the seriousness of the matter, so he strongly supported it, but he never expected that he would survive in the end.

...

"Master, how are you feeling?"

When he woke up, he saw Xia Xiang and Jiu Wu looking worried.

"I feel alright," the Walker said softly, then realized something and asked, "What's wrong with me?"

Xia Xiang and Jiu Wu exchanged a glance, their expressions becoming even more worried. Then Jiu Wu spoke up.

"Master, you've just exhausted your energy. You'll recover after proper rest."

The Swift Walker lay on the bed with a blank stare, as if he hadn't heard what Jiu Wu said.

"Xiangxiang, where is your other master? Why isn't he responding when I call him?" The Swift Walker looked at Xia Xiang with some anxiety in his eyes.

Xia Xiang pursed her lips nervously, then honestly replied, "Master never had a physical body; he disappeared after his energy was exhausted."

Shenzhou Xing's throat tightened, feeling dry and his gaze unfocused. He looked at Jiu Wu, then at Xia Xiang.

"But he might come back, just like before," Xia Xiang comforted him.

Jiu Wu echoed with concern, "Yes, Master, don't worry too much."

"Hmm," the Swift Walker's expression gradually calmed down, and he gave a faint "hmm," saying nothing more, silently digesting everything.

"You guys go ahead and get busy, I want to rest."

Xia Xiang and Jiu Wu could only leave with worries, and helplessly continued to busy themselves with their work, taking time out of their schedules to visit him every day.

Although the Swift Walker had returned to his previous state, cultivating daily and even joking with them, they still had a bad feeling, until—

After leaving a note, the Swift Walker disappeared...

“He went to find someone,” Xia Xiang said, holding the note.

“Master has almost recovered, it’s good for him to go out and about,” Jiu Wu said without any worry. “He’s over two hundred years old, he’ll take good care of himself, don’t worry.”

Jiu Wu patted Xia Xiang's shoulder to comfort her.
