In the underground cave, Lin Chuan urged the sword technique at will, and suddenly a silver light flashed in front of his eyes, and disappeared into the rock wall in an instant, leaving a smooth sword hole, which was bottomless.

A moment later, a silver light shot out from the rock wall, appearing in front of Lin Chuan's eyes like a silver dragon, and it was the Heaven Splitting Sword that had been re-refined.

At this time, the Sky Splitting Sword looked like it had changed a lot, the silver sword body was still only one foot long, but there were countless small silver spirit patterns on the surface, which looked very mysterious.

Bursts of strong sword qi fluctuations emanated from it, Lin Chuan was very satisfied with the power of the Heaven Splitting Sword after the re-refining, with the current Sky Splitting Sword, how strong the sword qi could burst out, Lin Chuan was not very clear, but his heart was full of expectations.

"Hehe, your kid's strength has improved again, what a monster, not only is he a powerful physical cultivator, but he also cultivates kendo, you must know that powerful sword cultivators are all very terrifying guys" Kaishan in Zhihai couldn't help but let out an exclamation when he saw the Sky Splitting Sword in front of Lin Chuan.

"Have you ever seen a powerful sword cultivator?" Lin Chuan asked curiously.

"I've seen a very terrifying guy, the cultivation of the merger period, but he can kill most of the masters of the Tribulation Period in seconds, fortunately, that guy has no hostility towards me, otherwise ......" Kaishan seemed to think of something fearful, and there was a faint fear in his tone.

"How powerful is it?" Lin Chuan heard the fear in Kaishan's tone for the first time, and he was a little concerned, not knowing what level of the powerful sword cultivator who was so praised by Kaishan.

You must know that with the improvement of cultivation, the gap in strength between each realm in the future is very large, don't look at the current Lin Chuan has been able to defeat most of the out-of-body stage cultivators, but when it comes to the merger period, it is difficult to say whether he can resist the tribulation period, and there is almost an unbridgeable gap between the two.

"Forget it, that realm is too far away from me now, the most important thing at the moment is to find the true spirit bloodline in it" Lin Chuan shook his head and took back the Sky Splitting Sword, although the power of the Sky Splitting Sword has increased a lot, but the disadvantage is that the mana consumed by each urging has increased a lot.

The sword fetus on his body had all been devoured by the Sky Splitting Sword, and he still hadn't made the Sky Splitting Sword reach perfection, Lin Chuan thought in his heart, after going out this time, he must find a way to get some more sword fetuses from the Sky Sword Gate.

After making up his mind in his heart, Lin Chuan cleaned up his mood, and then fell into contemplation, the power of the Sky Splitting Sword increased, but it still couldn't make Lin Chuan feel at ease, in this misty canyon, there were distraction period demon beasts, I am afraid that there are many big demons in the merger period like faceless demon beasts, and it is not realistic to want to enhance their strength to deal with such a big demon in a short time.

Lin Chuan thought about it, and finally discussed with Xiao Yin for a while, before deciding to refine a few hidden runes, of course, this time refining is not an ordinary hidden rune, but a powerful spirit rune that can conceal the spiritual sense of the demon beast during the merger period, and the difficulty of refining is self-evident.

"I didn't expect you kid to be a talisman maker, it's really a bit of a surprise" Kaishan saw Lin Chuan tinkering with talisman tools, and said with some surprise, a powerful monk like Lin Chuan, where does he have other energy to study the way of talismans, you know, the way of talismans, the way of Dan, the way of refining, and the way of formation are all broad and profound, and if you want to make achievements on it, you must spend a lot of time and energy, and it is impossible for ordinary monks to spend time and energy on this.

This is also the reason why there are very few alchemists, talisman masters, array mages, and refiners in the cultivation realm, most of the monks devote their energy to cultivation, and occasionally dabbling in this knowledge is also very limited.

Hearing that Lin Chuan was preparing to refine a talisman that could be concealed by the demon beasts of the merge period, Kaishan knew that Lin Chuan's attainments in the way of talisman were definitely not shallow, so he was surprised.

Lin Chuan didn't bother to pay attention to him, and concentrated on preparing, the talisman to be made this time is called the Void Talisman, which is an extremely difficult talisman to make, and there are many materials that need to be prepared alone, and they are scarce and difficult to collect.

However, in terms of Lin Chuan's treasure, it is not difficult to gather the materials for refining the Void Talisman, and Lin Chuan has been preparing since he arrived in the Ascension Immortal Continent, the original rune pen has been replaced with a higher-grade purple jade rune pen, and even the rune ink has prepared a higher-grade Tianling Sand, and the materials for making the rune are also the skin of a powerful demon beast that Lin Chuan exchanged for high points.

You must know that just collecting these things, Lin Chuan spent a lot of spirit stones, and at the same time, the sect points also consumed a lot, but everything was worth it, without these things, Lin Chuan would not have been able to make a void talisman at all.

Preparing talisman pens, talisman ink, and various tools, Lin Chuan spent a lot of effort, and Kaishan also came over with great interest, wanting to see Lin Chuan's talisman making ability.

But Lin Chuan left a sentence to cultivate and study the Void Rune and pulled Xiaoyin into the virtual space-time, to study the high-level spirit rune like the Void Talisman, it takes a lot of time, and the time acceleration of the virtual space-time has reached twenty times, and it is the time to use it.

Lin Chuan and Xiaoyin entered the virtual space-time together, this place has to be kept secret from the mountain, and the anti-heaven function of this virtual space-time is the biggest secret of Lin Chuan.

Once someone knows that Xiaoyin has such a terrifying ability, it will definitely cause a catastrophe, and being known by a giant like Kaishan will definitely cause him to covet it.

"Young Master, let's start now"

In the virtual space-time, a courtyard with a beautiful environment appeared out of thin air, Lin Chuan and Xiaoyin were busy inside, and an extremely complex rune was carved on the ground by Lin Chuan.

The twisted runes looked like countless small snakes were entwined together, which was many times more complicated than the ones Lin Chuan had originally made, and it made people's scalps tingle to look at.

Lin Chuan and Xiaoyin stood on the rune, and began to study and scrutinize little by little, gathering the knowledge of the two of them, and slowly analyzing the rune of the void rune, which was absorbed by Lin Chuan.

Fortunately, Lin Chuan originally had a lot of attainments in the way of the talisman, so it was easy to study, although it took a lot of time, but in this virtual time and space, time was Lin Chuan's biggest advantage, and he slowly analyzed the mystery of the void talisman.

Time passed quietly, Lin Chuan sat cross-legged in the cave, looking like he was cultivating, a month had passed, and Lin Chuan had no sign of waking up at all.

"That's it, a high-level talisman like the Void Talisman, he must need to study it for a long time, I'm afraid it will take at least a few years" Knowing the sea, Kaishan saw Lin Chuan entering the cultivation state, and muttered to himself, after all, it is a very difficult talisman, and with his knowledge, it must take a lot of time to study it.
