"He who possesses the Bixu Mirror can control all the waters of the world."
Xu Xian muttered the words to himself. If he could control all the waters of the world—rivers, lakes, seas, and even this nether water—couldn't they all be used for his own purposes?
The little book spirit suspended itself before the mirror, flying back and forth as it continued, "If I haven't guessed wrong, that giant tortoise phantom from before was likely an illusion projected by that old turtle using the Bixu Mirror and the water marsh beneath its feet. It wasn't its own power of delusion; that old tortoise is already at its wit's end. Otherwise, it wouldn't have ended up in such a miserable state at Master's hands."
Xu Xian's mind was not on that, however. The old tortoise was already in his grasp anyway.
He only wanted to know how to use this thing more effectively.
He had tried before, but after retrieving it, he couldn't use it anymore.
He followed up with a question, "Can I do what it did?"
"Of course!"
"Is it really possible?"
"It really is!"
The little book spirit told Xu Xian the method, and Xu Xian tried to establish a spiritual connection with the Bixu Mirror once again.
Once an invisible link was re-established, Xu Xian stood before the mirror and resonated with it using his divine sense.
At the same time, outside this space, the ten-colored sky above the water marsh began to churn with colorful clouds.
Then, a phantom of a white-haired demon was projected across the heavens.
It stood there, lifelike, overlooking the world between heaven and earth.
Xu Xian raised his hand, and the phantom followed suit. Xu Xian pressed his palm downward, and the phantom's massive palm also pressed down.
Though it was merely a projected illusion, the visual impact was no different from reality. It was as if a saint had descended to the mortal realm, pressing down a palm that could blot out the sky and sun.
The sense of oppression was immense.
It was even more realistic than before.
"Tsk, impressive!"
This move could be used anywhere there was a water marsh.
Large lakes, rivers, or the vast sea would all work. Of course, even in mountains or deserts where there was no water, one could call for a great rain and perform this move within the curtain of rainfall.
"This move is called the 【Bixu Phantom】, and it can be used to intimidate others," the little book spirit said. "If the day comes when Master fully gains the recognition of the Bixu Mirror and possesses enough strength, you won't just be able to bluff; you'll actually be able to suppress all things with the 【Bixu Phantom】."
Xu Xian felt a surge of anticipation and hurriedly asked, "What else is there?"
The little book spirit didn't hold anything back, revealing all the functions of the Bixu Mirror that Xu Xian could currently use.
Besides projecting phantoms, the Bixu Mirror could be used to see things beyond one's line of sight.
For instance, if Xu Xian thought of a person, as long as that person was near a river, stream, or sea, they could be simultaneously projected into the mirror.
It was like a surveillance system, turning the world's rivers into his eyes.
"Currently, Master's divine sense is too weak, and your bond with the Bixu Mirror isn't deep enough, so you can only use large rivers and lakes for spying. In the future, as Master's strength grows, a rain shower, a cup of water, or even a single drop of dew can become your eyes."
"One day, if you can reach the level of an immortal king or even an immortal emperor, what you see will no longer be limited to a single world or plane, but the entire Cangming galaxy. Any place, any plane—as long as Master wishes, all the waters of the world can become your eyes."
"In the truest sense, you can sit before the mirror and still know everything happening under heaven."
Xu Xian expressed that he liked this function very much; it was truly to his heart's content. It was practically a god-tier skill for peeping on others while they bathed.
Of course, Xu Xian wasn't that kind of person. He definitely wouldn't use this function to watch others bathe, right?
However.
If he could truly use a drop of dew as his eye in the future, there would be no one in the world he couldn't find.
An essential god-tier skill for scouting and eavesdropping.
By then, he wouldn't just rely on the Pupil of Insight for a bird's-eye view warning within a certain range; he could also rely on the Bixu Mirror to predict dangers far beyond his sight.
If a war broke out in the future, he could even know the enemy's movements and intentions in advance.
On a small scale, he could watch people bathe.
On a large scale, he could anticipate the enemy from a thousand miles away.
Truly not bad.
In addition to this function, the Bixu Mirror could also control water. Similarly, in the early stages, water control was limited to a certain range around the Bixu Mirror.
He could create waves, stir surges, and make rivers and seas churn.
In the future, as his cultivation improved, he could summon rivers and lakes within ten thousand miles with a single thought to submerge everything.
Likewise, he could use the Bixu Mirror to drain a lake or a large river in an instant, or even make a vast ocean disappear.
Naturally, the strength of these abilities depended on the improvement of Xu Xian's own realm.
The higher his realm and the stronger his power, the more he could unleash the Bixu Mirror's greater potential.
It was only logical; dharma treasures were ultimately external objects. In the end, they required the support of one's own strength.
He had to walk his own dao.
However.
One ability of the Bixu Mirror particularly appealed to Xu Xian: when encountering danger, he could dive into the mirror, and the Bixu Mirror would take him to any random water marsh within a thousand miles.
A true god-tier escape skill.
Currently, Xu Xian possessed the ability to predict risks, the Sword Tower, and powerful finishers like the little book spirit's move for direct confrontation.
A Heaven-Sealing Trapping Formation also made his accomplishments in formations respectable.
But if he encountered an irresistible risk, he had almost no means of escaping to safety. Take this trip to the Demon Abyss, for example.
First, he was targeted by an eighth-rank greater demon king and couldn't shake them off after running all night, forced into a last stand using the little book spirit's move.
Later, after entering the Nether Capital, he was targeted again and found it equally difficult to escape, forced to take the risk of throwing himself into the tiger's den.
Although both crises were resolved, Xu Xian had to admit that luck played a significant role.
Moreover.
He was never in full control of the risks, and instead, he had placed his life and death in the hands of others.
More often than not, he felt like a lamb waiting to be slaughtered.
If any part of the process had gone wrong or if a small hiccup had occurred, his life would likely have been lost.
Even though he had hidden trump cards every time, the risk still existed.
Ultimately, it was because he only had the ability to predict risks, but once he was passively caught in danger, he lacked the means to break free from it.
But things were different now. This function of the Bixu Mirror perfectly made up for his shortcoming.
In a single thought, he could appear a thousand miles away. Although he couldn't predict where he would appear, the enemy couldn't predict it either.
Furthermore.
A thousand miles was not a short distance. Without a teleportation formation, even a saint couldn't cross a thousand miles in an instant, and searching for him would also take time.
Most importantly, this ability could be used repeatedly.
This gave him a sense of confidence—the confidence to return to the Demon Abyss and get enough shadow soul stones. At least with this ability, he could ensure that he wouldn't die in the face of unknown risks.
