This sudden turn of events caused Lin Xie and the rest to be shocked. If not for them forming a battle formation, they might have already been killed by this mysterious existence.

"Crack!"

The sound of glass shattering caused Lin Xie and the rest to come back to their senses, their faces turning pale.

This was because their ever-victorious battle formation's protective barrier was only able to obstruct for a single breath before shattering.

Without the protection of the light screen, the black light continued to shoot towards them.

Within those ten or so beams of black light, every single one of them shot towards a youth or girl. As fast as lightning, they rapidly entangled them, then pulled them off the ground and returned them to the direction where the black light had come from.

Ling Yun looked up, and saw through the essence of the black light with his sharp eyes. It was a bunch of black vines as thick as an arm, and there were also many sharp thorns on them.

The youths that were entangled by the vines had pale, immature faces, but they did not panic. They circulated the spiritual energy in their bodies and brandished the weapons in their hands. The weapons ruthlessly slashed at the vines with sharp wind.

However, to their disappointment and despair, the powerful attack that even the Martial Masters did not dare to face directly did not cut through the black vines. There was only the sound of metal colliding with metal accompanied with the sputtering of sparks.

It did not even have a scratch on its skin. The vine's defensive power was incredibly strong. Even a Martial Master would not be able to cut it off.

Swoosh swoosh!

Just as the young boys and girls were about to be swept away by the black vines, streams of sword lights wrapped with scarlet flames tore through the air with a terrifying aura that seemed like they could burn everything down.

The scarlet sword flashed past the vines, and with a "pu" sound, the vines, which the youngsters weren't able to cut through even a layer of skin, were actually forcibly chopped apart.

With a 'shua' sound, the knots around the youngsters loosened. The youngsters fell to the ground, panting heavily. Their faces showed the joy of surviving a calamity.

As for the other end, it was actually entangled by the scarlet flames on the sword aura. The scarlet flames were like maggots on the bones, burning towards the vine, as if they were going to burn the entire vine along with its roots.

"Hiss, hiss, hiss!"

From afar, it seemed as if there was a strange, blood-curdling screech, and soon after, the burning vine suddenly shrank back into the pitch-black forest, disappearing without a trace.

Lingyun and the others looked towards the direction of the vine's escape. They wanted to see where its roots were, but they were disappointed to discover that the darkness in the forest seemed to have a miraculous effect. Even the flames were hard to see.

"Can you sense it?" Lingyun turned his head to look at Ling'er who was holding the Scarlet Feather Sword, and asked gently.

Although the defensive power of these vines was astonishing, they were as fragile as paper and easily chopped off under the sharp edge of the Scarlet Feather Sword.

However, these things were impossible to defend against and were extremely troublesome to deal with. Hidden in the pitch black forest, they had no other choice but to passively defend against it.

Ling'er frowned slightly as she nodded and shook her head. She said uncertainly, "There is a reaction, but it's very vague. I can feel that my flame is weakening at a rapid pace. It seems to have been extinguished by those vines."

Lingyun frowned and let out a bitter laugh, "Whatever, as long as we leave this forest, as long as it doesn't cause trouble for us, then we won't cause it any trouble."

"I'm afraid that's impossible!" Qin Feng shook his head with a bitter smile. Suddenly, his pupils contracted as he pointed to the severed vines, "There seems to be something strange with these vines!"

Ling Yun and the others immediately looked over, and saw that the vine's cut, which was as smooth as a mirror, was actually bleeding out a black, stinky liquid, as if it was injured …
