Mortal: I became invincible after becoming sworn brothers with Han Li.

After leaving the Yan Yang Palace, Wu Qingming bowed and took his leave, returning to the main hall of the mountain.

Li Yunfan then released the Cloud Piercing Boat and circled Fire Cloud Peak alone, trying to find a suitable location to open a cave dwelling.

About the time it takes for an incense stick to burn, Li Yunfan was already sitting cross-legged in the newly opened cave dwelling. At the same time, he set up a defensive formation with warning function that he had obtained from Xin Ruyin outside the cave dwelling.

Now that he is inside the Luoyun Sect, there is no need to worry about anyone invading, so he only set up a simple formation.

His cave dwelling not only had a front hall that was five or six zhang in size, but he also prepared a cultivation residence and a small insect chamber for himself. He modified it according to the insect breeding experience of that Spirit Control Sect cultivator, set up restrictions, and then put the captured illusion insect into it.

At this moment, Li Yunfan was holding a green jade slip, examining the secret methods for repelling and raising insects recorded within.

"Divine Control Array... Essence Blood Nourishment... Soul Imprinting..."

According to the secret techniques recorded in the jade slips by the cultivators of the Yuling Sect, for a spirit insect to recognize its master, a spirit control array must be inscribed on it when it is still an egg, and the cultivator must drip their own blood into it. In this way, once the spirit insect hatches, it will immediately recognize its master.

However, this method is obviously not applicable to the shapeshifter, a hermaphroditic insect that lays only one egg in its lifetime. Therefore, the only option is to use the simple and crude method of soul imprinting.

Having made up his mind, Li Yunfan immediately got up and left the cultivation room, going to the outside of the insect chamber where the illusion insects were kept.

However, the insect chamber was empty at this time, with no sign of the shapeshifters.

"At a time like this, you're still trying to be clever..."

Li Yunfan chuckled inwardly and scanned the insect chamber with his divine sense. He immediately discovered that the shapeshifting insect was lying motionless on the stone wall above his head.

If it were someone with an impatient temperament, they would have opened the barrier to check after seeing the shapeshifter disappear inexplicably, which would have given the shapeshifter the opportunity to escape.

However, this insect encountered Li Yunfan, who was able to detect its hidden figure with his divine sense when it was in the mid-Foundation Establishment stage, and now it could no longer hide from him.

He glanced up at a spot on the top of the insect chamber, then spread his fingers and the Purple Nether Heart Flame appeared instantly with a "poof." He flicked it gently towards the top of the chamber, and the flame flew towards the shapeshifting insect.

Sensing the dangerous heat, the shapeshifter ceased its concealment and quickly fled to the other side of the chamber.

With a thought, Li Yunfan unleashed his Purple Nether Heart Flame, which transformed into a curtain of fire and pounced on the Illusionary Insect, forcing it into a corner of the insect chamber.

He then formed a strange hand seal with both hands, chanting incantations. After a moment, the hand seal changed, and his divine sense rushed into the body of the illusionary insect. He opened his eyes wide and cast several spells in succession, beginning to condense a divine sense imprint within its body.

"Sizzle... sizzle..."

The intense pain caused the shapeshifter to let out a grotesque cry, its plump body writhing incessantly. But the pain not only failed to lessen, but instead penetrated deeper into its body, even causing its very soul to tremble.

A full quarter of an hour passed before Li Yunfan withdrew his divine sense, dispersed his hand seals, and showed some fatigue on his face, but his eyes were full of excitement.

The Soul Imprinting Technique is extremely taxing on one's spiritual sense. Moreover, since this was Li Yunfan's first time using it, he proceeded with extreme caution and slowness, which further exacerbated the consumption of his spiritual sense. Fortunately, his spiritual sense was exceptionally strong, which allowed him to succeed on his first attempt.

At this moment, the shapeshifter was already exhausted and lying on the floor of the insect chamber. If Li Yunfan could not still sense its breathing, he would have thought that he had accidentally killed it.

Fortunately, everything went very smoothly. The next step was to nourish him with his essence and blood every day until his own aura was completely imprinted in his soul.

After dealing with the matter of the shapeshifting insect recognizing its master, Li Yunfan returned to the cultivation room, sat cross-legged on the futon, and began to regulate his breathing to recover his depleted spiritual energy.

As the saying goes, cultivation knows no time; a thousand years have passed in the blink of an eye!

Before anyone knew it, one year and three months had passed since Li Yunfan joined the Luoyun Sect.

On this day, Li Yunfan, who was cultivating, suddenly sensed something, opened his eyes, and probed out of his cave with his divine sense. After seeing the person standing outside the formation, he couldn't help but murmur.

"Could it be that the sword-testing tournament is about to...?"

With these thoughts flashing through his mind, Li Yunfan immediately got up and left the cultivation room. After arriving outside the cave, he took out a dark yellow array plate, raised his hand and made a few gestures on it. The array plate immediately emitted a yellow beam of light, which shot into the array in the air.

Then the light curtain surrounding the cave disappeared at a visible speed, revealing the entire cave and Li Yunfan's figure.

"Junior Brother Li, your formation is quite impressive. Could it be that you are also an expert in this art?" Wu Qingming walked up to Li Yunfan as soon as the formation dissipated and said with a chuckle.

"I wouldn't call myself an expert, but I did study it for a while in my early years. I hope you'll forgive my ignorance, senior brother," Li Yunfan replied with a slight smile.

A hint of surprise flashed in Wu Qingming's eyes. This was quite unexpected for him. He hadn't expected that the other party not only had a fast cultivation speed, but had also studied formations.

"Senior brother, is it because the Sword Trial Tournament is about to begin?" Li Yunfan didn't offer any further explanation but asked directly.

"That's right, I'm here to remind you, junior brother, that the Ancient Sword Sect has already issued a notice that the Sword Trial Tournament will be held in six months." Seeing that the other party was unwilling to say more, Wu Qingming did not press further and nodded.

Li Yunfan's expression remained unchanged upon hearing this, but he secretly thought to himself, "Six months from now... then I'll take advantage of this time to further cultivate my physical body!"

Just as he was pondering to himself, Wu Qingming spoke up again.

"Although Junior Brother has agreed to participate in the Sword Trial Tournament, he probably doesn't know the specific rules yet, right?"

Without waiting for Li Yunfan to speak, he immediately began to explain.

"Each sect can register only thirty disciples to participate in the Sword Trial Tournament, for a total of ninety, and only the top ten will be selected. Furthermore, both Qi Refining and Foundation Establishment stage disciples will participate, among whom..."

Li Yunfan listened quietly to Wu Qingming's explanation. Although he knew some of the rules, it was still beneficial to listen to the other party's explanation.

The rules of the entire Sword Trial Tournament were not difficult, and Wu Qingming finished explaining them in no time. He even reminded Li Yunfan not to be careless, as the sword cultivators of the Ancient Sword Sect were quite strong, and he should be careful even if his opponent was not at the late stage.

Li Yunfan humbly accepted this. After Wu Qingming left, he raised the formation again and returned to his cave to begin cultivating the Spirit Devouring Undying Body.

Yue Tian also cultivated this technique, and even the accelerated method within it. Naturally, his storage bag contained some demon beast essence blood, which now conveniently benefited Li Yunfan.
