Mulberry Island is a large island in the East China Sea, located close to the coastline of the Dragon Sparrow Empire, where an Imperial Legion was once stationed, but recently it has been found to be completely lifeless.

The Xuanyuan Ancient Clan has close ties with the Dragon Clan's royal family, and today they received a request for help to assist in the investigation of the Sangyu Island incident, and after the Battle of the Dragon Head, they decided to send the top ten disciples of this year to investigate.

Tang Yin followed Xuanyuan Nishang's side, riding a huge flying demon beast, looking down from the sky above Sangyu Island, and there was no life at all.

What kind of power can rob the whole island of life?

Tang Yin couldn't figure it out, with his experience in the Spirit Sword Continent, it was really hard to imagine what would be caused by the destruction of such a large-scale vitality?

"Let's go down and take a look, everyone hold your breath first, don't come into contact with the outside air!"

After the monster mount landed on Sangyu Island, Xuanyuan Nishang reminded everyone to be careful that the air could be poisonous.

The ten people in this group are all extraordinary, and they don't even need to be reminded by the fairy in neon clothes, they all suspect in their hearts that this place must have been released with poison.

Except for the intense poison, no human force can do such serious damage.

Falling to the ground, scorched earth everywhere. Plants wither, shatter at the touch of a button, and even a slight wind blow away a dead tree that remains its original type.

Tang Yin lowered his head, squatted on the ground and grabbed a handful of soil, put it in front of his nose and sniffed, he couldn't help frowning, as an alchemist, his sense of smell was far from being comparable to that of ordinary sword masters.

There is a faint imperceptible smell of sulfur in the scorched earth, but this smell is very light and difficult for ordinary people to detect.

If this kind of thing was found above the Nine Heavens, Tang Yin would definitely think of the consequences of the bomb explosion at the first time, but this is the Spirit Sword Continent, although gunpowder is also used as a material for the production of "Lei Zhenzi", but he does not have such power, and he cannot cause such serious damage consequences.

"What the hell is it?" Xuanyuan Yulong couldn't help but exclaim.

"Then ask our dragon head, Senior Brother Tang Yin doesn't know what you have discovered?" Xuanyuan Undefeated saw Tang Yin squatting on the ground and asked with a little schadenfreude.

Although he lost to Tang Yin in the individual competition, he still ranked 10th in this year's dragon head.

At this moment, he directed everyone's attention to Tang Yin, undoubtedly wanting to see the other party make a fool of himself.

But he didn't expect that Tang Yin just smiled faintly, raised the scorched earth in his hand, and said: "I don't know if you senior brothers and sisters have noticed that there is a smell of burning sulfur in this soil, although it is a little light, but as long as you smell it carefully, it is not difficult to find!" ”

"Huh?" Listening to Tang Yin's words, the fairy was the first person who did not question it, she personally grabbed a handful of scorched earth and put it in front of her nose and smelled it, "Sure enough, there is the smell of burning sulfur." ”

Everyone was sure that what Tang Yin said was an important clue, sulfur was not abundant on Sangyu Island, so such a large-scale sulfur smell must have been brought by outsiders.

"But what does that mean?" Xuanyuan was undefeated and continued to be unrelenting, although he was unwilling to lose to a newcomer, but he couldn't see Tang Yin singing and harmonizing with the goddess he admired.

"Senior brother, this is your mistake. Doesn't such a large-scale arson that burned Sangyu Island to the ground overnight, and no one escaped alive? Xuanyuan Qingwu said lightly, "The one who can do this is definitely not a person, let alone an ordinary person, and Qingwu dares to guess that there must be thirty or fifty powerful sword masters at the same time." ”

"But these are all ordinary people, and the sword master can't make a move on ordinary people!"

"For whom does such a provision work?" Xuanyuan said disdainfully, "There are so many crazy people in this world, it's hard to guarantee that there won't be a few scum among the sword masters." ”

"Senior Sister Light Mist is talking about the Evil Sword Master?" Xuanyuan asked.

"Evil Swordsman?"

Everyone was shocked, but only Tang Yin was an exception.

Tang Yin scratched his head and asked embarrassedly, "Senior sister, what is an evil sword master?" ”

"In the process of the sword master's advancement, the spirit is controlled by the evil spirit, and he will become an evil sword master, losing his rationality and being extremely cruel." Xuanyuan Nishang quietly explained to her little junior brother.

The Evil Swordsman is an unspeakable secret, though he has been with him since the appearance of the Sword Master.

But in the world outside the Sword Master, he didn't know about the existence of the Evil Sword Master, otherwise it would seriously shake the Sword Master's esteemed status among ordinary people.

Tang Yin had only been a true sword master cultivator for less than two years, so he naturally didn't know about the existence of the evil sword master, but he didn't have anything to make a fuss about it.

As the leader of this trip and a candidate for the next patriarch, Xuanyuan Nishang must still have a secret that others can't know about the strange disappearance of the 300,000 army.

Seeing everyone's eyes, Xuanyuan Nishang had no choice but to speak: "The matter is more serious than you imagined......

It turned out that before this, in addition to being the naval base of the Dragon Bird Empire, Sangyu Island also imprisoned a powerful evil swordsman a hundred years ago.

And that evil sword master was not only from the Xuanyuan Ancient Clan, but also a senior of the Xuanming Island lineage.

"What?"

"I see!"

"In this way, there is no life here, it must be related to the predecessor of the Xuanyuan Ancient Clan, no wonder the Dragon Clan let the Xuanyuan Clan deal with it on their own!" Tang Yin smiled coldly in his heart.

"In that case, let's find the dungeon where the seniors of the clan are imprisoned." Xuanyuan Yunyang said.

Xuanyuan Nishang shook her head, "The above is just Nishang's own speculation, as for the entrance to the dungeon, I don't know, and the elders didn't tell me before they came." ”

Soon, everyone walked all over Sangyu Island, a small island with a radius of only more than ten miles, and no living creatures were found, not even a bird stopped here.

But at this moment, the ground under Tang Yin's feet was weak, and one leg actually fell into the ground.

Touch!

Tang Yin reacted very quickly, and as soon as he slapped the ground with his palm, the whole person rose into the air, but the two people who didn't react fast enough had already completely fallen into the ground.

"Storm and dragon clouds!"

Tang Yin shouted violently, and with a wave of his palm, a tornado suddenly rose on the ground, sweeping away all the soft dust, and an entrance to the underground tunnel was presented in front of everyone.

"Could this be the entrance to the dungeon?"

The two children of the Xuanyuan clan who were in a panic, after being rescued from under the ground by the Xuanyuan Jade Dragon, stood at the entrance of the tunnel and looked down and said.

"I'm afraid this is it." Xuanyuan Yulong glanced at the ground and said.

"Let's go down and see what secrets are in this underground prison!"

Xuanyuan Nishang said and walked down the passage first.
