If the old man was three points younger, he would look exactly like the old man whom the Human King Bai Cang entrusted his son to before his final battle in the Human King's Tomb.

Boom! Boom! Boom!

At this moment, a series of thunders, like thunder across the sky, exploded one after another from Xu Feng's body.

Xu Feng let out a long roar, and his fighting spirit soared into the sky, transforming directly into a deep blue flame-like column of air, reaching a height of nine feet, nine feet, nine inches, nine points, nine centimeters, and nine millimeters! !

However, seeing this scene, the old man shook his head, seeming a little dissatisfied.

It seemed that in his opinion, this blue fighting spirit was not perfect!

However, the next moment, a look of surprise suddenly appeared on his old face, and he looked at Xu Feng with relief.

Xu Feng, who was originally sitting cross-legged on the ground, suddenly changed his hand gestures, and the whole person was lifted up by the blue fighting spirit. A vast and ancient aura quietly emerged. This aura was older than that of the old man, the human race, and even seemed to be older than this mysterious world!

"Wild pattern!"

"Congeal!"

A loud voice came out from Xu Feng's mouth, and a wisp of fighting spirit like a purple flame was suddenly born in the blue ocean. At first it was just a tiny bit, and then like a drop of ink dripping into clear water, the entire ocean of fighting spirit turned purple in an instant.

Colorful purple is supreme!

The height of the air column increased by one millimeter out of thin air.

Ten feet in an instant! Perfect!

The purple gas column above Xu Feng's head broke through the limit and was ten feet high at this moment!

A relieved smile finally appeared on the old man's face, and his posture even straightened a little.

"Yes, the purple aura is ten feet high, and it is the appearance of an outstanding person."

Just like that, the old man stood there quietly, watching the purple fighting spirit on Xu Feng's body gradually extinguish and converge into his body.

A breath of perfection emanated from Xu Feng, but soon disappeared, as if it had been hidden, and a new breath reappeared from Xu Feng.

Then, a purple vertical line flashed between his eyebrows, and Xu Feng slowly opened his eyes.

The first blood tempering was completed!

An excited smile appeared on his face.

Finally, after absorbing the qi and blood in the bodies of the three immortals, these eight bloodlines were finally complete.

One hundred and eight blood vessels ran through his body, connecting heaven and earth, like one hundred and eight avenues to heaven, instantly connecting with Xu Feng's body.

For a moment, his fighting spirit surged, his blood rushed to the sky, and even the fighting spirit that he had already tempered with great difficulty to blue was directly catalyzed into purple.

Xu Feng felt as if he had infinite power for a moment, and his heart was so excited that he could hardly control himself.

However, he soon calmed down, because in addition to being a cultivator who had reached the great perfection of Blood Tempering, he was also a Yuan cultivator who had reached the eighth level of He Dao.

With the aura of the Dao in his body and his mind protected by the Dao, he is much more peaceful than other low-level cultivators.

After calming down his qi and blood, Xu Feng slowly stood up and clasped his fists towards the old man in the courtyard and said, "Junior Xu Feng, nice to meet you, senior."

The old man nodded slightly: "Not bad."

Xu Feng clasped his fists and said, "Thank you for your praise, Senior."

The old man looked at him and smiled, "Come in and talk."

Xu Feng nodded and strode towards the courtyard. The huge pressure seemed to blow away like a breeze, and he walked into the courtyard easily.

Then, he turned to look at Zi Buyu and said to the old man: "Senior, this is my friend, and he is also one of the talents of the human race today. I wonder if he can come in as well? Oh, by the way, he also has the battle weapon Cangmang left by Senior Ren Wang!"

Xu Feng winked at Zi Buyu.

Upon hearing this, Zi Buyu quickly took out a broken gun from his storage bag and showed it to the old man.

The old man suddenly raised his eyebrows and raised his hand. The broken gun flew directly into his hand, and Zi Buyu did not intercept it.

Touching the broken gun, the old man's face showed a trace of nostalgia and emotion: "Alas, in the blink of an eye, you have ended up like this."

He sighed, shook his head, and threw the broken spear back into Zi Buyu's hand: "Hold Cangmang and enter. This formation recognizes the aura of this spear."

Watching Zi Buyu cautiously walk into the courtyard, Xu Feng suddenly became curious. Can this formation recognize people?

The old man seemed to have sensed his curiosity and explained, "This formation has spirits. It was set up by the Human King himself back then to suppress the gray fog in this area, so the Human King's soldiers will naturally recognize it."

"Gray fog?" Xu Feng looked at the gray fog around him in surprise. Was this thing suppressed by the Human King himself? In other words, was this gray fog so powerful?

"That's right," the old man nodded, looking at Xu Feng with a kind look, "Back then, this gray fog came from nowhere and swept across the entire Red Region, so the Human King had to set up a large formation to suppress it. This fog is extremely dangerous. Otherwise, he would not have gone up to the sky to fight without fully recovering..."

"Forget it. We'll have plenty of time to talk about these past events later. I see you came here today because you have something important to discuss with me?"

The old man waved his hand and said lightly.

Xu Feng didn't expect the old man to be able to see this. He took a deep breath and said respectfully, "I haven't asked for your name yet, senior."

"As the old saying goes, the Emperor of Mankind personally appointed the human race's divine general."

The old man smiled.

"Greetings, Senior General." Xu Feng and Zi Buyu bowed together.

The old man shook his head and said, "Forget it. The human race's tradition has collapsed. There are no gods left. They are just half-dead people trapped in the ghost den. If you have any questions, just ask."

"Senior Gu, do you know what a fairy is?"

Xu Feng looked at the old man with burning eyes.

"Immortals?" The old man raised his eyebrows. "Are you talking about the remnants of the immortals or the immortals from outer space?"

Xu Feng and Zi Buyu looked at each other and asked in surprise, "There are immortals from outer space?"

General Gu Yan nodded and said, "This world... is called Xuantian Star. It is a huge sphere. The human race only owns one-tenth of this wild star. In addition, a large number of worlds are shrouded in this gray fog."

"When the Human Emperor opened up a piece of pure land for the human race, he used the Red Territory as the foundation and expanded to eight surrounding regions. However, it was still less than one-tenth of this world. One day, an immortal descended from the sky, and the human race realized that this world was just a remote corner of the star field."

"Some immortals who descended from heaven left descendants in this world. These people wanted to occupy this world and drive out the human race. They are the so-called remnants of the immortal race. And those immortals who occasionally passed by from the outside world without any ill intentions are called immortals from outside the sky."

"But they are actually just monks from another cultivation system."

The old man looked at Xu Feng and asked, "So what kind of immortal are you talking about?"

Xu Feng understood and said, "What I'm talking about is the remnants of the immortal race!"

The old man snorted coldly: "How far have these damn guys progressed now? Is there any royal tribe left in the human race?"

Xu Feng and Zi Buyu looked at each other blankly again: "What is Wangbu?"

The old man was startled for a moment, then said with a gloomy expression: "The Wang tribe is gone......"

"Forget it, let's not talk about this anymore. Just tell me your request. I think you came here desperately, not just to get your doubts resolved, right?"
