The use of vine confinement primarily involves wood-based spiritual energy and the real vines that are induced. Yi Jue changes this by first using Gang Qi to restrain the enemy, then simulating and transforming into vines, and finally using the induced vines to confine the enemy. There is a process of transitioning from illusion to reality.

This transition from illusion to reality demands high control over spiritual energy, requiring at least a high-rank cultivation level to skillfully master. However, only with such transformation can Yi Jue achieve the goal of fast spellcasting.

Therefore, the Qingmu Prison Cage technique can be considered an upgrade of vine confinement, though the changes are indeed significant. Tiegu regarded it as an ordinary wood-based technique, defending as usual and unexpectedly suffering a hidden loss.

But how could Tiegu be an easy opponent? Realizing this technique had little impact on him, he swiftly cast another teleportation spell and hurled it at the Jade Spore Skyworm again—it had forcefully broken out of the previous teleportation, so he cast it once more, seemingly with the intent to prioritize eliminating it.

Yi Jue’s lips curled into a cold smile, controlling the transformation of the vines, "Confinement!"

She possesses the power of confinement, but this technique involves spatial rules. With her cultivation level at the Nascent Soul stage, she could hardly master many spatial rules. Controlling a Golden Core is no problem, but against Tiegu, who is also at the Nascent Soul Peak, only close-range casting has a chance of success.

At this moment, the vines confining Tiegu were transitioning from illusion to reality, quite close to him.

Tiegu smirked slightly, a white flash at the center of his brow, "Retribution Causality!"

"Art of Causality..." The observers couldn’t help but exclaim, "It’s actually a Fate Talisman... Does Lingmu Sect possess such a great power?"

The mystery of the Art of Causality surpasses even spatial techniques, yet their difference isn’t much. However, the Art of Causality involves destined secrets, greatly harming one’s fortune—not only injuring the user but also severely impacting those who developed the causality technique.

As a result, throughout the Tianqin Plane, there are hardly any causality techniques. Some cultivators develop abilities and occasionally achieve insights, but mainly keep it to themselves, because once it spreads, the backlash they face greatly increases, essentially harming both oneself and others.

Suddenly realizing Lingmu Sect has a Fate Talisman, many people opened their mouths in disbelief—this is not merely the Art of Causality!

Regardless of the technique, generally, the talisman comes after the existing technique. The technique provides the foundation, while the talisman simulates the casting process, ultimately being copied onto talisman paper.

Of course, some miraculous phenomena arising from the Heavenly Dao are termed Innate Talismans, which can be exceptions.

Actually, another reason well explains which is rarer between techniques and talismans—one can only use a technique once learned, but anyone who can activate a talisman can use it.

Anyway, the causality symbol at Tiegu’s brow truly startled many people.

Yet at this moment, someone snorted coldly; it was Elder Chiang Mai from the Jinwu Sect, who had lived for over two thousand three hundred years, "It’s not that scary. Playing with spirit plants and spirit wood... improving the natural environment and receiving feedback from the Heavenly Dao is also Retribution Causality!"

Upon these words, others instantly understood—so that’s the "Retribution Causality"!

Chiang Mai indeed spoke correctly. Tiegu obtained this talisman from a True Sage of the Lingmu Sect who enjoyed cultivating spirit wood. Through feedback from the Heavenly Dao, he comprehended "Retribution Causality" and, being fond of talismans, wanted to challenge himself.

Ultimately, he succeeded, but dared not make more. He created only three in total, each disciple receiving one—fortunately, it’s a feedback-type talisman, otherwise making even one would be excessive.

This True Sage ventured out a thousand years ago. Tiegu became good friends with one of his disciples and knew of the existence of the Fate Talisman. Engaging in this battle with Yi Jue, he specially sought out that disciple to borrow the talisman—when life and death are at stake, one must use connections, lest it be too late.

This "Retribution Causality" talisman, though bearing the word feedback, doesn’t sound harmful. However, as causality dictates, there must be an outcome for every cause! There is no distinction of right and wrong, good or bad!

Tiegu received an immobilizing strike from Yi Jue, without even defending, because his intent to kill the Jade Spore Skyworm was false; he aimed to injure Yi Jue!

Experts in the Earth Martial Arts World battle with a notion of "feigning weakness"; so, digging traps in battles between Nascent Soul cultivators is similarly normal.

He chose this moment to retaliate because, during a focused duel between Nascent Soul individuals, finding an opening is extremely difficult. As long as there’s a sliver of chance, one must seize it, even if it means using the precious Fate Talisman.

Lo and behold, Yi Jue never anticipated his plan, thus unguardedly suffering a solid confinement backlash—ultimately, her combat experience was a bit lacking, though intrinsically strong, she hadn’t encountered enough of such crafty tricks.

Tiegu also suffered from the confinement, and the causality talisman merely ensures feedback, unable to prevent injury. However, his body was strong enough. Upon succeeding, he decisively issued a command with his mind, "Break confinement!"

Nearby, a spatial node suddenly opened, and a vine shot toward Yi Jue like lightning. Others couldn’t identify this thing, but how could it escape Elder Yu Teng of the Spirit Plant Sect? She cried out in shock, "It’s actually the Transpatial Vine, has it finally succeeded?"

As she spoke, she was about to dodge outside the defensive formation, because she knew very well what this was.

She had heard of this vine long ago. When the Lingmu and Spirit Plant sects hadn’t split, they had accidentally obtained a small piece of Jian Mu, which refused to thrive. The upper tiers dared not speak publicly about it but privately deliberated several times on how to use this Jian Mu.

The final decision was to use Jian Mu to cultivate spirit plants, first planting spirit fungi on it, then using spirit insects to gnaw on the fungi, and finally using spirit plants that can consume the insects to eat them...

By that time, the bloodline of Jian Mu might have already been very diluted, but it would eventually mutate into a new spirit plant.

To speak of the Lingmu Sect, they are indeed quite crazy; truly a group of experiment maniacs, wasting the famous Jian Mu in such a manner. But cultivators are sometimes really obsessive, no less than regular scientific zealots.

As for why not use spirit insects to directly gnaw on Jian Mu? Instead, adding an extra step, because... it can’t be gnawed at.

Jian Mu is a natural wonder, capable of supporting a universe; how could little spirit insects possibly gnaw through it? If such insects existed, wouldn’t some universes easily collapse?

However, spirit fungi can grow on Jian Mu because it also develops dead bark, and many spirit fungi favor this growth environment, while Jian Mu does not suffer much substantive damage.

Yet, even so, it took the Lingmu Sect three thousand years to cultivate the first spirit fungus.

Then there was a long experimentation process to cultivate spirit insects capable of gnawing on the fungi, which also took quite a bit of time.

When the experiments reached the third step, the stage of finding spirit plants to prey on spirit insects, the Lingmu Sect fractured, and there was a great cataclysm, with many things disappearing without a trace, including Jian Mu.

Over ten thousand years later, the Lingmu Sect finally confirmed that Jian Mu had fallen into the hands of the Lingmu Sect, due to too many prior experiments, Jian Mu had somewhat collapsed, and could no longer be cultivated; the Lingmu Sect could only continue these kinds of experiments.

Reportedly, the Lingmu Sect’s hatred of the Lingmu Sect deepened because of this piece of Jian Mu. They believed such a treasure should be diligently cultivated; the Lingmu Sect destroyed this rare treasure—if it were alive, used as spirit wood for fighting, who could possibly contend?

Later, there was news that the Lingmu Sect had already cultivated a plant with the bloodline of Jian Mu, but it wasn’t spirit wood or something like Man-Eating Grass, but a vine.

Elder Yu Teng’s master did not harbor significant animosity towards the Lingmu Sect, so there were also good friends within the Lingmu Sect who shared this information, which was passed on to Yu Teng later.

Yu Teng learned that the vine was called Transpatial Vine, and even knew some of its shape. However, according to reports, this thing’s divine sense was pitifully small, making it difficult to control. It still needed improvement, and careful screening was required before use, with a chance that was less than one in a hundred.

Upon seeing a plant that seemed familiar, she finally realized—had it truly succeeded?

She hadn’t interacted much with Yi Jue, but at this moment, she had to step in; she really understood the terror of the Transpatial Vine.

However, just as she was about to teleport, Elder Kumu grabbed her, speaking coldly, "In a life-and-death battle, just watch, Lingmu Sect cannot afford to lose face."

Kumu hated the Lingmu Sect even more than she did, and was eager to act right then, but they were surrounded by onlookers, "You have to trust her."

"What’s the harm in conceding?" Yu Teng, as a common mindset among female cultivators, thought, even though her relationship with Yi Jue was very ordinary, "At worst, others say we are unreasonable, but we can’t just not care about Yi Jue."

Kumu pointed in a certain direction, smiled bitterly, and said, "Look over there... Feng Jun has gone out."

Sure enough, Feng Jun stepped out of the Jinwu defensive formation, a cultivator at the Initial Golden Core Stage, appearing abruptly in the True Immortal battlefield.

Elder Yu Teng was not young, but sometimes quite stubborn, "If an outsider can go out, why can’t I?"

Elder Kumu rolled her eyes at her and asked sternly, "Do you know how to deduce battle situations? Or do you think your deduction skills are higher than his?"

He was right; Feng Jun indeed deduced that the battle situation would be unfavorable to Yi Jue, which is why he stepped forward.

Regarding the Transpatial Vine, Feng Jun had received a warning from the big boss earlier, knowing that there was a variant of Jian Mu here, but he believed it was meant to deter him from suddenly entering and considered it a tactic by the Lingmu Sect.

This time, the big boss did not detect the Transpatial Vine, and Feng Jun’s deduction relied on distance; he was not qualified to inspect the battlefield mid-fight, so he did not discover the Transpatial Vine’s ambush.

As it happens, Tiegu also made a lot of effort in this regard, at least managing to hide the Transpatial Vine from the big boss—during a life-and-death situation, he undoubtedly chose the most reliable method, no matter how many Spirit Stones were spent, it was a minor issue.

In the on-site deduction, Feng Jun repeatedly discovered the presence of the Transpatial Vine, but alas, his cultivation level was too low. During battles at the Nascent Soul Peak, he couldn’t even issue a warning with divine sense.

He could ask others to issue a warning, but in a Nascent Soul battle, outside prompts would be looked down upon, and Yi Jue couldn’t afford such disgrace!

Thus, in a critical moment, he could only step out of the Jinwu defensive formation!
