Longevity: Starting from Refining Gu

```

If Chen Qing was the most dazzling person of this era,

then Dan Yunzi was the most dazzling person of the era he lived in.

Brilliant against brilliant.

The only issue was that though Dan Yunzi had a thousand years of cultivation, Chen Qing didn't even have a hundred.

Dan Yunzi, with the Martial God's possession, fiercely battled Chen Qing in front of Haoran Temple.

Waves of punches like rain, two giants attacked each other relentlessly.

Chen Qing took two punches, his body resounding with thuds.

He thought to himself, "What True Monarch cultivated was indeed stronger than my own wild path."

Though Chen Qing's Heavenly Earth Transformation Skill didn't compare to Dan Yunzi's, relying on his possession of the Six Dao Ghosts made him equally matched in strength with Dan Yunzi.

Occasionally, he would manage to exploit Dan Yunzi's unfamiliarity with the Sky Splitting Skills, delivering a punch, but under the influence of This World Restless, Dan Yunzi instantly returned to peak condition.

The effect of This World Restless was even more formidable than his Emperor Earth.

Emperor Earth only granted an Undying Body, but This World Restless was more domineering, healing any injury in an instant, unless the opponent was killed immediately.

Chen Qing asked himself if there was no conflict of interest with Dan Yunzi.

Dan Yunzi was a Daoist Lord, while he was a King, completely different paths.

Thus, Dan Yunzi purely felt that Chen Qing was a threat, which was why he acted this way.

Chen Qing sighed to himself, this battle could only be fought with full strength, though he regretted having to hold back and not use the power of the Void River.

If he could use the Void River to enhance his Sky Splitting Skills, Chen Qing had confidence he could surpass Dan Yunzi.

But since it was just a spar, Chen Qing had no interest in revealing too much of his power.

At most, he might use the power of the Six Dao Ghosts and Emperor Earth.

Dan Yunzi descended like a Martial God, his massive body agile, landing three punches on Chen Qing in a swift motion, causing him to cough up blood.

Chen Qing assumed the Six Dao Demon God Form, four arms swinging, tearing dozens of cracks in the surrounding space, frequently clashing with Dan Yunzi.

Chen Qing also felt a sense of dissatisfaction, thinking that if he had a King-level Weapon, it would not be so troublesome.

Dan Yunzi seemed to be a weapon in himself, whether fists, kicks, or body, everything was a terrifying weapon in his hands.

This was a Great Grandmaster whose mastery of Fist Skills, Leg Skills, and Body Cultivation was all at the Grandmaster Realm, seamlessly integrated.

Chen Qing had always used his Martial Arts realm to suppress others, but this time, he felt suppressed.

Dan Yunzi was like a larger version of Chen Qing, with skills similar to Gu's and Chen Qing's, and a thousand years more experience in cultivation.

Seeing Dan Yunzi was like seeing his own future.

After three days of relentless combat, Chen Qing wiped the blood from his face.

Dan Yunzi looked at Chen Qing, who was still eager to fight despite being covered in blood, and suddenly remembered when he first came to this mountain.

At that time, he also stirred up endless turmoil, carrying grudges behind him.

Yet, Master still took him in.

How similar he was to Chen Qing at this moment!

Dan Yunzi punched Chen Qing back, waved his sleeve and said, "After fighting me for three days, haven't you thought of using the Azure Darkness Eye to observe my mana flow path?"

Chen Qing immediately realized, activating the Azure Darkness Eye to observe Dan Yunzi's mana flow, then internally examined himself to find that the opponent's mana flow was much more complex than his own.

Was this the complete pathway of the Heavenly Earth Transformation Skill?

Chen Qing tried to imitate it, and indeed, after optimizing parts of his flow, his strength increased, improving by 4.5 times compared to before.

Dan Yunzi, seeing Chen Qing had adapted, gestured for him to continue, "Again!"

Chen Qing, now interested, engaged Dan Yunzi once more. As they exchanged blows, Dan Yunzi shouted, "Strike with all your might, understand?"

"You are a pure body cultivator, your entire strength lies in your Gu and physical power, so you must move like lightning, act like Mount Tai pressing down!"

"Find ways to mobilize all the Gu on you to serve your actions!"

"If it can't be used, what use it is?"

Listening to Dan Yunzi's guidance, Chen Qing suddenly thought of the Feather Transformation Immortal Tree. If he could cultivate beneath it for some time, integrating his mana and Gu, his power would significantly improve.

Unceasingly battling Dan Yunzi, he gained more insight, gradually familiarized himself with his power, and became more adept at using it.

Dan Yangzi opened the main gate, strolled out, "This is how it should be, you're all brothers, where does all the grievance come from?"

Dan Yunzi responded, "Master brother, have you and Master thought it through to take Chen Qing in?"

"The karma he carries is vast, his mind complex, there will be endless trouble in the future!"

Dan Yangzi waved his hand, "As if you weren't a bundle of trouble when you first came to Haoran Temple, didn't I help settle it?"

Dan Yunzi sighed deeply, "If it weren't for seeing that he's half a point stronger than I was when I first entered the Mystic Gate Realm back then, why would I give such advice?"

Dan Yangzi said, "All right, stop this before you wake Master, neither of you will have a good ending then!"

"Since you've come to understand Chen Qing's foundation, let's put an end to this!"

Chen Qing saw Dan Yunzi withdraw from his Martial God state and returned to his human form.
