A man from the Big Dipper, starting his charlatanship at Mount Tai.

"Hmm, this child is teachable."

"However, before that, you need to improve your strength further. The Fourth Level of the Four Extremes is already quite good, but you are still a bit short of being able to sweep away your peers."

"Does Little Ancestor mean... to go into seclusion and cultivate asceticism?" Yan Ruyu asked.

"There's no need for you to go into seclusion. Next, I'm going to take you to find something, or rather, to find a secret technique."

"Secret technique? What secret technique? Is it related to the gathering?"

"It's related, and it's not," Lin Xiu explained.

"That secret technique is incredibly profound, and it has miraculous effects in both offense and defense. If you can comprehend it in advance, you will naturally have a better chance of winning at the gathering. However, this secret technique is hidden deep within a special terrain, and whether you can comprehend it depends more on your personal opportunities and comprehension."

Yan Ruyu understood the implied meaning.

"Does the young master mean that Ruyu might not be able to comprehend it?"

"Who can say for sure about matters of chance? Judging from your foundation, you have a good chance of comprehending it. But if you ultimately fail to comprehend it on your own initiative, it's alright."

"Are you alright?"

Yan Ruyu felt it was still quite problematic, after all, this was a powerful technique certified by Lin Xiu.

"If you can't understand it, it means you don't have enough comprehension."

If you lack understanding, make up for it with hard work.

“I have a course here called ‘Innate Dao Diagram Stress Resistance Training’. If you can pass it, I will give you a graduation reward.”

"Innate Dao Diagram Stress Resistance Training?"

Yan Ruyu frowned, realizing she didn't quite understand Lin Xiu's meaning. She remembered that the Innate Dao Diagram was something descended from heaven, wasn't it? Could Lin Xiu possibly control the Heavenly Dao and make it send down the Innate Dao Diagram?

.......

"That's right, the Innate Dao Diagram Pressure Resistance Training."

Lin Xiu smiled and nodded.

"Do you know what kind of tribulations one will encounter when the Holy Body breaks through to the Four Extremes?"

"I have heard that when the Holy Body breaks through the Four Extremes, a Primordial Dao Diagram will descend to suppress the Holy Body's Dao Foundation, cutting off its path forward."

As Yan Ruyu spoke, her expression suddenly became somewhat subtle, as if she had remembered something.

She recalled that when Lin Xiu brought Ye Fan to find her, he had completely fooled her with the reason that "the curse of the Holy Body has become stronger with the times."

Lin Xiu noticed her expression and coughed tactically:

"There's no need to dwell on the past... In short, the Primordial Dao Diagram does indeed exist, and it's extremely troublesome."

"The Innate Dao Diagram Pressure Resistance Training I mentioned means having you stay by my side and endure the suppression of the Innate Dao Diagram at all times."

"You'll pass when your resilience reaches 200% of your current level."

"what?"

Yan Ruyu's beautiful face paled slightly.

She had heard that the Innate Dao Diagram was an insurmountable barrier, even for those with exceptionally talented bodies. Countless brilliant individuals with such bodies had fallen before this obstacle.

Now Lin Xiu wants her to use the Innate Dao Diagram to cultivate?

“Little Ancestor…” Yan Ruyu hesitated.

"The Primordial Dao Diagram was bestowed by the Heavenly Dao to obliterate the foundation of the Sacred Body, and its power is terrifying beyond compare. Although Ruyu has some confidence, she knows that among those of the same level, she is still inferior to the Sacred Body. If even the Sacred Body cannot overcome this tribulation, how can Ruyu withstand it?"

At this point, Yan Ruyu suddenly remembered something:

"By the way, how did you manage to pass through the Innate Dao Diagram back then, little ancestor? Your realm is clearly above the Four Extremes."

"I?"

“I have encountered the Innate Dao Diagram twice. The first time, I relied on the divine sense of the Great Accomplished Sacred Body to make a move, and the second time, Senior Azure Emperor made a move. Neither of them relied on my own efforts to get through.”

"........"

Upon hearing this, Yan Ruyu was left speechless, unsure whether to laugh or cry.

After all that, Lin Xiu couldn't force his way through using his own strength?

"Then...why did the young ancestor still ask Ruyu to cultivate using the Innate Dao Diagram?"

"Even you couldn't overcome this calamity, yet you expect Ruyu to face it? Isn't that... a bit too harsh?" Yan Ruyu felt that Lin Xiu's expectations of her were too high, and she truly couldn't bear them.

"No, no, you've misunderstood." Lin Xiu waved his hand.

"The innate Dao diagram that I made you endure was not the one that was descended by the Heavenly Dao, but... one that I copied myself."

"Huh? You copied it yourself?"

"Young Ancestor...you can even copy the Primordial Dao Diagram?!"

Yan Ruyu knew that Lin Xiu possessed the talent to replicate Dao essence, as evidenced by the Dao essence within the roots of the Chaos Green Lotus. But she never imagined that Lin Xiu could even replicate a calamity like the Innate Dao Diagram, a tribulation bestowed by the Heavenly Dao.

Lin Xiu shook his head helplessly as he looked at Yan Ruyu's shocked expression.

It seems Yan Ruyu's vision isn't very broad either.

The next second, Lin Xiu had a thought.

"Om~"

On Lin Xiu's white Taoist robe, the black and white Tai Chi diagram on his chest suddenly shone brightly and slowly floated out from the surface of the robe.

The Tai Chi diagram grew larger in the wind, instantly transforming into a shape about ten feet in diameter, hovering above Lin Xiu's head. The yin-yang fish in the diagram slowly rotated, emanating a terrifying aura that suppressed all paths.

"This is... the Primordial Dao Diagram!"

Yan Ruyu's breath hitched.

"To be precise, it was a copy I made, specifically to suppress my own Innate Dao Diagram," Lin Xiu corrected.

"I've been cultivating with it under my influence ever since I started talking to you."

Yan Ruyu looked at the slowly rotating Tai Chi diagram, then at Lin Xiu who remained calm, and felt that her worldview had been greatly impacted.

"Little Ancestor...you've been cultivating with it on your head all this time?" Yan Ruyu's beautiful eyes opened slightly.

Chatting? Cultivating? Is this something a human would do?

"Otherwise what? Is there anything in this world that can make one's Daoist cultivation more perfect than the Primordial Dao Diagram?"

"The Primordial Dao Diagram is extremely wondrous. It was designed by the Heavenly Dao to obliterate a person's path to Dao. It can completely ignore and restrain all of that person's Dao techniques, and obliterate their very essence."

"But... on the other hand, if a person completes the trial of the Innate Dao Diagram, it means that he has eliminated the weaknesses and shortcomings of his own Dao techniques and completely surpassed his former self."

"This is an extreme test. If you can get through it, you will be completely transformed."

"Are you... confident?"

......

Feeling Lin Xiu's gaze fixed on her, Yan Ruyu took a few deep breaths and tried to calm herself down.

She looked at the Innate Dao Diagram, then at Lin Xiu, and suddenly a question came to mind.

“Young Master, there is something Ruyu still doesn’t understand.”

"The Primordial Dao Diagram was bestowed by the Heavenly Dao to obliterate the foundation of certain human beings. Even if you have the ability to copy it, the Primordial Dao Diagram you copy should be targeted at you personally."

"Is it inappropriate to use it to suppress Ruyu?"

"Ruyu knows that her cultivation level is far inferior to that of the young ancestor. If this diagram is truly designed for you, I'm afraid... Ruyu won't even last a breath."

Upon hearing this, Lin Xiu burst into laughter.

"You are indeed meticulous. But you are overthinking it. The Innate Dao Diagram that I copied was indeed originally designed for myself."

"But... I can adjust its power."

"The power of the innate Dao diagram descended by Heaven is fixed and will automatically adjust according to the strength of the person undergoing tribulation to ensure that it can be completely obliterated."

"But the one I copied can be controlled at will. I can adjust it to only exert 30% or 50% of its power, and use it to hone the skills of cultivators of the same level."

"As for the targeted issues you're worried about... I also have a way to solve them."

Yan Ruyu blinked: "What method?"

“I can replicate your human form and Daoist aura,” Lin Xiu explained.

"Humanoid Daoist Aura?" Yan Ruyu was slightly taken aback.

“That’s right, the humanoid Dao Aura. Because your strength is below mine, I can completely replicate your humanoid Dao Aura. Then, I can use the innate Dao diagram I replicated to approach your humanoid Dao Aura and push the innate Dao diagram to evolve on its own, gradually adjusting it to the state most suitable for suppressing you.”

Yan Ruyu was stunned.

Can you do this?

"and many more!"

Yan Ruyu suddenly thought of something, and two blushes instantly appeared on her cheeks.

“Little Ancestor… the humanoid Daoist aura you spoke of, could it be that it replicates my complete human form?” Yan Ruyu fully unleashed her imagination, and her face immediately turned red.

.......

Lin Xiu was taken aback at first, then realized what was happening and was left speechless with a mixture of amusement and exasperation.

What are you thinking?

"What I copied was only your recent state of Dao, your Dao rhythm, your flow of magical power, your bloodline Dao... not your whole person."

Yan Ruyu breathed a sigh of relief upon hearing this, but her cheeks remained bright red.

"I'm...I'm sorry...Ruyu misunderstood and misunderstood Xiao Zu."

Lin Xiu waved his hand, indicating that he didn't care.

A few seconds later, Lin Xiu looked at Yan Ruyu again and said seriously:

"So, Yan'er, are you willing to begin this Innate Dao Diagram stress resistance training?"

Yan Ruyu took a deep breath, a determined look flashing in her eyes.

"Ruyu is willing."

"Okay." Lin Xiu nodded.
