Lu Yuan's arms were clamped tightly and he could not swing his sword at all.

The space was too small and Guo Pu couldn't get out.

The vine demon's chest kept rising and falling, making a human-like laugh.

The laughter was so gloomy that it made people shudder.

He struggled to push open the vines, but with a pair of outer walls, most of the force was dissolved by the slippery vines.

Lu Yuan gradually felt short of breath and his consciousness began to blur.

The little vine demon actually wants to use such despicable means to control me!?

Lu Yuan slightly bent his fingers, and five rays of white light flew out from the Rong Ring.

Flying Borer Knife!

This set of flying knives was damaged in the battle before, and was later given to Lin Fuzhang together with Guo Pu for repair.

It is now completely repaired.

When Lin Fuzhang gave it to Lu Yuan, he told him that the Feiji Dao can be made large or small, and can be used both offensively and defensively.

Now in such a narrow environment, this is where it comes in handy!

The flying knives pierced the vines and quickly formed a cylindrical shape.

Then it turned suddenly.

The flesh and bones of the vines inside the column were twisted into green mud by the crazy rotation.

The vine demon was in pain, and the strength of Lu Yuan's chest restraint was reduced.

The flying knife immediately merged into one and turned into a metal drill.

Lu Yuan's consciousness moved, and the drill bit was aimed at the heart of the vine demon and suddenly pierced it.

"Hiss, hiss..."

The vine demon let out a strange cry, quickly opened its chest, stretched out its hand and threw Lu Yuan out.

The other hand dug into his heart, trying to pull out the drill bit.

In just two breaths, the vine demon pulled out the drill bit and his heart together!

The heart is dark green and only three fingers thick.

But the vine demon did not die after the heart was dug out.

Green mud surged up in its hand again, covering the Flying Borer knife.

Then his arms stretched out rapidly and wrapped around Lu Yuan.

Lu Yuan understood. This monster has multiple hearts!

"Qilin Thorn!"

A powerful straight line attack.

The sword blade suddenly became longer, and the sword light was as fast as lightning, causing a series of explosions in the air.

A sword hit the vine demon's fist and the blade was gone!

The vine demon was injured, but it was born with strange strength and directly raised its fist to lift Lu Yuan into the air.

Lu Yuan quickly drew out his long sword in the air, gathered his strength and slashed down.

"Falling Lin Slash!"

The sword blade was not mixed with any elemental power, and he poured the purest profound energy into it.

"Boom!"

There was a loud noise, and one of the vine demon's arms was cut off!

The cave's rubble flew and huge holes were cut into the ground and cave walls.

But the fairy sword spirit embryo on the ground was not affected much.

However, the vine demon just screamed strangely and watched as another arm grew out of the broken arm.

Endless growth is the characteristic of plant monsters.

Lu Yuan released a blazing fireball from his left hand.

This fireball has been strengthened by the "Fire Essence" method, and its power has been greatly increased.

The vine demon started to burn, but was quickly swallowed up by its juice.

This attack was just a feint from Lu Yuan.

He quickly threw out the Heart Refining Flag, and a magic circle was immediately set up.

The fingers were slightly bent, and the formation mirror flashed into his hand.

Lu Yuan sensed the mysterious energy of heaven and earth, silently recited the incantation, and shouted:

"cut!"

As soon as he finished speaking, the edge of the array lit up a strange purple-red color. The vine demon was right in the center of the array.

The "Gangfeng Formation" rolled up hundreds of blades, constantly cutting the monsters inside.

"Swish, swish, swish!" The sound of the wind blade breaking through the air can almost burst the eardrums.

The cave floor was also cut into pieces.

The vine demon was crushed to the ground by the huge force of wind, unable to move for a moment and could only howl miserably.

But its vitality is extremely tenacious, and in the blink of an eye it can slowly lift its arms against the wind pressure.

"I'll give you another ride!"

The Demon Sword of Annihilation swung rapidly, weaving a red and white web of light.

The sword skill "Snow Dragon" and the Gangfeng Formation were intertwined, completely ruining the illusion of the vine demon's escape.

The howl of the vine demon gradually became weaker, and the strength of its struggling and beating gradually became smaller.

All the branches, leaves and vines were twisted into thick black and green grass pulp.

After a few breaths, everything returned to tranquility.

The air is mixed with the fragrance of vegetation and putrid evil spirits.

The ground and cave walls were covered with shocking sword marks.

A large pool of sap on the ground is slowly flowing into the pond.

The pond was originally full, but in the battle just now, all the water in the pond had evaporated.

Lu Yuan looked at all this and felt extremely depressed:

I couldn't hold back my energy just now, and all the spiritual embryos must have been destroyed by me!

I am still too impulsive and reckless. If Master were here, I would never be like this!

While blaming himself, he searched for the remaining spiritual embryos with a sense of luck.

When he turned over a few rocks, a surprising scene appeared!

Many spiritual embryos were lying on the ground in a mess, with their roots protruding.

But they were almost not cut off by the sword energy, there were just slight marks on them.

It is indeed a fairy tree!

Lu Yuan was overjoyed, and immediately carefully picked six spiritual embryos and wrapped them in the special talisman given to him by Lin Fuzhang.

If these precious materials are directly put into the Qiankun Bag or Rongjie, the medicinal properties and effects will quickly decrease.

The weapon refiner has special bags, rings, and talismans, all of which are used to keep them fresh.

Although part of the spiritual energy of the spiritual embryo was absorbed by the vines, fortunately the loss was not much and it can still be used.

There are no guardian beasts here. They should have been driven away by the vine demon. No wonder there are many vines growing on the spiritual embryo. Lu Yuan thought.

He immediately searched for the demon elixir of the vine demon. But the elixir was of wood and water attributes.

While putting away the demon elixir, he thought: It's a pity that sword making requires a metallic demon elixir... But good things come hard, and I should be able to encounter it next time.

After checking around again, Lu Yuan sensed Liu Yuansi with his consciousness and immediately sent a message to him: "Yuansi, come on."

Liu Yuansi suddenly heard Master's call in his mind and was startled.

After confirming that it was Lu Yuan's voice, he felt relieved and ran over with his head in his hands.

Seeing what he saw in front of him, he was stunned and couldn't take a step forward.

"Teacher...Teacher...Master, that big guy was killed by you...?" He made a gesture of cutting his throat.

Lu Yuan moved his neck: "Well, I almost caught it."

"Master, master, let me help you hammer your shoulders!" Liu Yuansi trotted over.
