Han Li calmed himself, glanced at the Hot-Fire Immortal carrying the remains of Mu Yan beside him, and then swept his gaze slightly forward.

The underground hall was dim and silent, the front dark and unknown where it led.

"Fellow Daoist Li, let's go."

Hot-Fire Immortal said, walking ahead, flipping his hand to take out a walnut-sized, bright pearl, and throwing it casually.

A white arc of light flew up to the dome and embedded itself in it.

The pearl released a snow-white light above their heads, illuminating the entire underground hall.

Han Li's eyes narrowed, and he saw the entire hall was empty, with only a strange wooden chair in the center, shaped like two intertwined dwarf tree branches, half green-black and half withered yellow.

"I thought this place was where Martial Uncle Mu Yan stored elixirs and immortal herbs, but I didn't expect there to be nothing at all." Hot-Fire Immortal said, a hint of regret flashing in his eyes.

"Since this secluded place was established independently, it must have its unique features. Perhaps something else is hidden here." Han Li said, withdrawing his gaze from the wooden chair.

"Not bad."

Hot-Fire Immortal nodded and continued walking forward with Mu Yan's corpse on his back, stopping beside the green-black wooden chair. He used his immortal spiritual power to help bend the corpse's limbs, so that it sat upright on the wooden chair behind the table.

After that, he respectfully bowed to the corpse.

Han Li was not in a hurry to search, but waited for Hot-Fire Immortal to do everything before searching the hall with him.

After a while, the two walked over from both sides of the hall, exchanged a glance, a trace of disappointment flashing in their eyes, and shook their heads at the same time.

"Judging from the situation here, no hidden compartments or secret restrictions have been found." Hot-Fire Immortal said.

"It seems that this place has probably been searched clean." Han Li also sighed.

As they were talking, his gaze suddenly jumped, and the corner of his eye caught Mu Yan's corpse seeming to move slightly.

Han Li's heart tightened, and he quickly turned his head to look. Mu Yan's remains were sitting quietly on the strange wooden chair, without any movement, but that moment just now did not seem like an illusion.

"It shouldn't be, I was just trying my luck, and others are even less likely to know that there is an underground palace here..." Hot-Fire Immortal obviously didn't notice any movement and continued to say.

"Perhaps it was already looted when the True Word Sect was destroyed..."

Halfway through Han Li's words, his expression suddenly changed, and he exclaimed, "Fellow Daoist Hot-Fire, be careful..."

As soon as his voice fell, Mu Yan's corpse suddenly lit up with a strange green light. Black evil energy condensed at the huge wound on his abdomen, and in just an instant, it had formed a grape-sized black round bead.

The surface of the bead was surrounded by black gas, which looked quite strange.

Immediately afterwards, the strange wooden chair under Mu Yan's corpse suddenly seemed to come alive. The branches on it suddenly scattered to both sides and grew wildly, sweeping towards Hot-Fire Immortal like vines.

All of this seemed long, but in reality, it only happened in an instant.

Although Hot-Fire Immortal was reminded by Han Li, his reaction was still a beat slow. Just as he pulled himself away to dodge, he was swept by several withered yellow vines, and his arm was instantly entangled.

"Ah..."

Only a scream was heard from his mouth. The robe on his arm instantly turned to ashes, and black scorch marks appeared on the exposed skin. The flesh instantly became dry and shriveled, and the skin became as dry and ugly as bark.

Hot-Fire Immortal immediately opened his mouth wide, and a raging crimson flame spewed out from his mouth, spreading towards the wooden chair along the withered yellow vines entangled in his arm.

However, for some reason, this seemingly extremely fiery flame seemed to be poured with nectar when it landed on the wooden vines. It just dripped down and couldn't burn the withered yellow vines at all.

At this moment, a sound of piercing through the air rang out, and a blue sword light suddenly lit up, wrapped in strands of golden lightning, and slashed down from the air.

With a "chi la" sound!

The withered yellow vines broke in response, spurting out gurgling dark green liquid and bursts of fierce black smoke.

After Hot-Fire Immortal escaped, he immediately retreated and stood side by side with Han Li. He raised his other palm and pinched out a golden rune with blue patterns, which he stuck on the wound on his arm.

"Si si si..."

Accompanied by bursts of slight sounds, bursts of fishy white steam began to emerge from the rune.

"Fellow Daoist Li, what's going on?" Piercing pain struck in waves. Cold sweat broke out on Hot-Fire Immortal's forehead, but he had no time to care and hurriedly asked.

"I'm not sure either, but judging from the situation, your Martial Uncle Mu Yan seems to be turning into a fiend..." Han Li frowned and said.

He stared at the strange wooden chair, seeing that the vines on it had all retracted, shaking like the disheveled hair of a demon, but no longer actively sweeping towards the two of them.

"This...how is this possible? So many years have passed, why didn't he turn into a fiend earlier or later, but now?" Hot-Fire Immortal said with a face full of disbelief.

"I'm not sure about the specifics, but it seems that it's mostly related to the strange wooden chair under him..." Han Li said, his gaze falling on the wooden chair as he pondered.

Hot-Fire Immortal was momentarily stunned when he heard this.

After a moment, his eyes flashed, as if he had suddenly woken up, and he hurriedly shouted, "That's not a wooden chair, that's..."

His words were interrupted by Han Li's exclamation:

"Not good, he's about to form a fiend embryo... Fellow Daoist Hot-Fire, quickly help me to block those strange vines."

Mu Yan, who was sitting on the wooden chair, was shaking violently at the moment. Under his eyelids, the two eyeballs that should have been decayed were shaking violently, moving back and forth as if trapped in a nightmare, as if they were about to open in the next moment.

At the same time, Han Li's figure had already leaped forward, and he directly summoned nine Azure Bamboo Bee Cloud Swords, merging them into one and stabbing straight at the place where the evil energy was condensing into an embryo in Mu Yan's corpse's abdomen.

As soon as his figure entered the area of tens of feet near the corpse, the green-black and withered yellow vines immediately twisted wildly, enveloping him from all directions, whipping and entangling him.

Seeing this, Hot-Fire Immortal quickly summoned the golden ancient mirror, threw it forward, pinched a magic formula with one hand, and shouted loudly:

"Freeze!"

After this shout, the entire golden ancient mirror trembled violently, and a complex rune appeared on the surface. The mirror released countless golden rays of light, covering all the space around Han Li.

Under the dazzling golden light, a clear fluctuation of the law of time immediately rippled out. The vines that were shooting towards Han Li instantly seemed to be trapped in a quagmire, and their speed became slow.

The Mantra Treasure Wheel in Han Li's body instantly reversed, and his speed suddenly increased. He flashed into the dense vines, and the golden light shone on the blue long sword. The Evil-Warding Thunderball condensed by the Thunder Summoning Technique directly broke through the barrier formed by the intertwined green-black vines and pierced into the hollow abdomen of Mu Yan's corpse.

With a "boom" sound, thunder roared!

The dazzling golden electric light instantly bloomed, turning into countless tiny golden snake-shaped electric currents and shooting in all directions, tearing the evil embryo that had barely taken shape into pieces.

The broken evil embryo turned into thick evil energy, which evaporated and dissipated completely in the Evil-Warding Divine Thunder.

Han Li was in a trance in the brilliant golden electric light and saw Mu Yan's corpse open its eyes. In the pupils, a figure was reflected, but it was not Han Li, but Qi Mozi.

In an instant, the golden thunder light surged again under the **** of ten thousand strands of sword energy, not only tearing Mu Yan's corpse into pieces, but also blasting the Two-Life Tree below to pieces.

"Don't..."

"Alas..."

A cry and a sigh sounded in Han Li's ears and heart, respectively from Hot-Fire Immortal and Demon Light.

Han Li's figure landed, and he put away the long sword in his hand. Demon Light sighed again in his heart: "Fellow Daoist Han, what a pity... I just closed my mind for a moment, alas..."

Han Li naturally knew that what he regretted was the evil embryo that was about to take shape. With this thing for him to devour and absorb, his cultivation would definitely increase by another level, but Han Li didn't want that to happen in his heart.

A Demon Light in the early stage of Grand Luo was already a bit difficult to control. If he continued to widen the gap, who knows what other problems would arise.

"Fellow Daoist Demon Light, the situation is urgent, and it was an expedient measure..." Han Li responded with his mind.

"The opportunity has not arrived, it is just not meant to be..." Demon Light could only sigh quietly.

Hearing this, Han Li stopped talking to him, temporarily isolating the connection between the Flower Branch Space and the outside world, and turned to ask Hot-Fire Immortal:

"What's wrong, Fellow Daoist Hot-Fire, why did you speak out to stop me just now?"

Hot-Fire Immortal had already put away the ancient mirror and walked over in a hurry, looking at the strange wooden chair that had become scorched black, with a face full of regret: "Fellow Daoist Li, you this...alas..."

"What exactly happened?" Han Li frowned and asked.

"This thing is not a wooden chair, but an immortal plant called the 'Two-Life Tree'. It is said that Martial Uncle Mu Yan relied on this thing to survive the tribulation of evil decay back then." Hot-Fire Immortal pointed at the "wooden chair" with only half of its scorched trunk left and said.

"What..." Han Li's heart was filled with remorse when he heard this, but there was nothing he could do.

He bent down, wanting to check carefully to see if there was any way to save the Two-Life Tree. As a result, he found a section of green branch inside the withered black tree trunk. After pinching it out with two fingers, he found that it was a jade slip in the shape of a branch.

"Could this be..." Hot-Fire Immortal raised his eyebrows and hurriedly asked.

"Whether it is the *Grand Five Elements Illusory World Sutra*, Fellow Daoist, you will know if you check it yourself." Han Li generously handed the jade slip over and said.

Seeing this, Hot-Fire Immortal was a little embarrassed to take it. After thinking for a moment, he said:

"Forget it, Fellow Daoist Li has saved my life several times, and I have always held on to sect prejudices, it's really... Whether the *Grand Five Elements Illusory World Sutra* is inside or not, Fellow Daoist Li will check it, but after that, this thing..."
