The sign-in opportunity surprised Lin Jiufeng.

But he looked forward to what he would receive.

After all, this was the door to the Mountain Sea Realm—the door to a hidden world.

It has been so long since the door to this hidden world was opened.

Hence, Lin Jiufeng judged that he would receive a unique and rare reward upon signing in.

Lin Jiufeng had long figured out the reward patterns for signing in.

The more dangerous a place was, the greater the reward would be for signing in.

The more unique a place was, the more precious the reward would be.

As for some places that could be repeatedly signed in, only the first time was the best. The repeated sign-ins yielded worse rewards than the first.

This should be the first time in 15,000 years that the door to the Mountain Sea Realm was opened.

It didn't even matter whether they knew where the door was—as long as they didn't have the key to open it. They could only take a look at the door, not beyond it.

Today, Lin Jiufeng stood in front of the door and signed in.

He was the only one that could do this.

Lin Jiufeng really looked forward to the reward he would receive from his sign-in here.

[Sign-In successful. Received the One Spirit Into Three Pure Ones Skill!]

"One Spirit Into Three Pure Ones…"

"This is the supreme treasured skill of Daoism." Lin Jiufeng was pleasantly surprised.

He was familiar with all sorts of books…

This One Spirit Into Three Pure Ones happened to be recorded in one of the books he had read.

The book said that it was tremendously powerful Daoist treasured.

But there were no detailed records of just how powerful it truly was.

Boom!

A stream of memories rushed into Lin Jiufeng's head. The information made him understand just how exactly strong was this One Spirit Into Three Pure Ones treasured skill.

The One Spirit Into Three Pure Ones would initially be as strong as a cultivation technique. But as the practitioner's comprehension deepened and he found his own conclusion about the charm of the Great Dao, its might would increase to that of a treasured skill.

After comprehending the charm of immortality, it would become an immortal technique.

Considering how the treasured skill scaled with the practitioner's cultivation base and comprehension, it was understandably a precious skill that could be in a cultivator's arsenal for his entire life.

After the sign-in process was over, Lin Jiufeng now had a supreme Daoist treasured skill in his arsenal.

"Miss Hong, you can go back now. I want to stay and observe this door for a while."

Lin Jiufeng suddenly spoke up.

"Okay!" Miss Hong was straightforward.

She decisively left without disturbing Lin Jiufeng.

After Miss Hong left, Lin Jiufeng said to the white cat, "I'm going down to investigate and also to cultivate for a while. Keep an eye out for strangers and don't let anyone disturb me."

"Okay." The white cat immediately agreed.

Thump!

Lin Jiufeng jumped down and dived into the water.

He then sat cross-legged and meditated.

Rumble!

Waves of powerful energy surged out of his body.

They penetrated through his entire body, nourishing his limbs and bones.

Especially his divine soul, his divine soul split into four pieces.

One controlled the main body, the other three transformed into the Three Pure Ones.

Lin Jiufeng slowly cultivated in the One Spirit Into Three Pure Ones Skill

The price that one had to pay to cultivate this treasured skill was indescribably high.

Of course, the higher the risk, the higher the reward…

This treasured skill could eventually become an immortal technique.

Right now, Lin Jiufeng's Three Pure Ones could independently exercise his full might.

They were fragile compared to his main body…

Nevertheless, the fact that three other Lin Jiufeng's could appear on a battlefield at a moment's notice was a terrifying enough fact that no one could possibly ignore.

The stream of information that he received from the sign-in opportunity made it so that he instantly reached the highest peak possible with his current cultivation base and comprehension.

A large amount of spiritual energy entered his body, increasing his cultivation base.

Lin Jiufeng began to climb rapidly on the 33 steps of the Boundless Realm.

Tonight, he sat cross-legged in meditation under the water.

The absence of sunlight made the water too dark for anyone to see anything in it.

But Lin Jiufeng's body was glowing.

Not only his body, but his three other souls were also giving off light.

The Three Pure Ones was formed using Lin Jiufeng's main body as the base.

They weren't an avatar or something like the Death Surrogate Puppet.

The One Spirit Into Three Pure Ones allowed one's divine soul to split into three other parts, each of which had the full combat power of the main body.

In this aspect, this treasured skill was unprecedented and unique.

In the depths of the vast lake, the four sources of light gathered together to form a small and resplendent circle.

If someone was nearby, they would immediately notice such a glaring light.

Fortunately, this happened at night.

Fortunately, the white cat was around to scare off unwanted strangers.

She looked at her surroundings warily, her claws ready to spring out at any moment.

The white cat hadn't been idle during this period of time.

She was about to make a breakthrough into the Supremacy Realm.

She also had her own domain.

In short, she was very powerful by today's standards.

Protecting Lin Jiufeng was no problem at all.

Fortunately, the night remained calm throughout.

No one came, nor did anything unexpected happen.

It was a peaceful night.

The next morning, the small resplendent circle had already disappeared.

Lin Jiufeng was currently making a breakthrough.

The Boundless Realm was a long staircase that meandered upwards.

There were a total of 33 steps in the long staircase.

A gargantuan effort was necessary to take another step.

Even Miss Hong—someone from the previous era was currently only on the tenth step.

Of course, one could also blame the sluggish recovery rate of the world's spiritual energy.

If it recovered faster, Miss Hong's cultivation base would've been higher today.

But unfortunately, the recovery rate has slowed down to a crawl so none of them managed to arrive, let alone, break the boundary of the Boundless Realm.

But Lin Jiufeng broke it.

He was already at the fifteenth step, but after obtaining the One Spirit Into Three Pure Ones skill, he became even more powerful. The world's spiritual energy converged on him and pushed him even further beyond.

After a night and a day, Lin Jiufeng arrived at the 33rd step.

The peak of the Boundless Realm.

The realm afterwards was the King Realm.

When the sky darkened again and the night fell once again, Lin Jiufeng, who was at the bottom of the lake, opened his eyes.

His aura was restrained in his body.

He became akin to that of an ordinary young man.

But in fact, he was like a volcano…

Silent, restrained, but ready to erupt and surprise the world once he made his move.

Lin Jiufeng raised his head and looked toward the starry sky.

The resplendent stars flickered in the night sky.

The night was beautiful.

Lin Jiufeng leaped and directly flew out of the water.

The moment he flew out of the water, his body looked dry as if he never dived into the water.

Meow~

The white cat called out and flew into Lin Jiufeng's arms.

She said curiously. "Your smell changed yet again."

"How did it change?" Lin Jiufeng asked.

"You smell better, like 10,000-year-old agarwood. I didn't think so at first, but then the fragrance got deeper tonight. You smell like a peerless treasure." The white cat buried her head in Lin Jiufeng's arms and sweetly replied.

She was burying her head in Lin Jiufeng's chest!

But Lin Jiufeng was never wary of the white cat's actions.

What evil intentions could the white cat have?

She just wanted to get closer to him.

Lin Jiufeng was still thinking about his cultivation base. "It's a pity that I didn't comprehend the charm of immortality. Otherwise, the One Spirit Into Three Pure Ones would have already become an immortal technique."

Lin Jiufeng's current cultivation was at the Boundless Realm, 33rd step.

This realm was neither high nor low.

He was in a relatively awkward spot.

The charm of the Great Dao that he comprehended wasn't the charm of immortality.

In that case, the One Spirit Into Three Pure Ones became a treasured skill, not an immortal technique.

'But even if it's just a treasured skill, it's still a supreme treasured skill. Amongst the treasured skills that I have, it's worthy of being number one.' Lin Jiufeng thought to him.

'Let's just wait until I've got some clues about the charm of immortality. Once I've comprehended the charm of immortality, the One Spirit Into Three Pure Ones would then become an immortal technique.'

'There's no need to hurry. I'll take this step by step.' Lin Jiufeng comforted himself.

It wasn't like he couldn't improve anymore.

Looking down, the white cat seemed intoxicated by his thick and broad chest.

"All right, that should be good now…"

"I'm going to open the door to the Mountain Sea Realm now."

Lin Jiufeng raised the white cat and said with a doting smile.

The white cat looked reluctant to leave his chest. "You're opening it right now?"

"Of course…"

"Go stand to the side. I'm about to insert the key."

Lin Jiufeng put the white cat down and accurately hurled the key down.

It directly flew to the center of the door.

Click!

The key was inserted.

Dong!

The door of the Mountain Sea Realm trembled and slowly opened.

The entire Northwest Territory vibrated.

Many people could feel the vibration, but they had no idea what was going on.

As a result, they could only frown at the vibration in confusion.

Only Miss Hong stood in the oasis city and looked at the huge lake with a grim look.

With the door opened, no one knew if what was about to happen next was a blessing or a curse.
