To cultivators, the Boundless Valley actually wasn't that deep. Even in the areas that Lin City had explored, it was only a few hundred feet deep. As long as one was careful, they could easily descend from the cliff.

However, although the deep valley wasn't very tall, it was very wide.

For example, the current location of Lin City was about a few miles wide.

Therefore, when Lin City seemed to sense that someone was approaching from behind, he immediately and stealthily left his position, and went around to carefully investigate.

Although this place was outside of the range of the azure flame's explosion, the scorching and berserk flames still burnt all the nearby grass and trees. However, it gave Lin City the condition to hide its traces.

He quietly leaned behind a large tree that was half burnt, looking towards the direction of the elemental energy fluctuation. Immediately, he saw a few figures slowly moving forward. The direction they were moving towards was precisely the direction of the Azure Flame's direction.

"As expected! Not a demon beast, but someone is coming! "

There were many fierce beasts in the deep valley as well, and there was no lack of Demonic Beasts. However, ever since they came down from the Lin City, they had never seen even a single mouse.

Thus, when Lin Cheng felt the fluctuations of elemental energy, he immediately realized that someone was coming.

Not long after, these figures appeared clearly in Lin Cheng's line of sight. He immediately furrowed his brows, "Are they students from the Eastern Region Academy?"

He was slightly curious. Why would it be students that came down?

Logically speaking, since this strange phenomenon had occurred, it was obvious that a strange treasure had appeared. Then, there would definitely be experts from the Eastern Region Academy. Why were the first ones to arrive instead of a few students?

"Could it be that these students were in the middle of training in Boundless Forest, and they saw that something was amiss over here? That's why they decided to rush over here first?" This thought flashed across Lin Cheng's mind. He wondered if he should knock these people out before hearing the sounds of their conversation.

"The azure flames are right in front of us. Everyone, be careful. Be on high alert!" Don't just focus on collecting the flames, be careful of wild beasts and demon beasts attacking you. "

"Brother Chen, if there really is a demon beast ambushing us, then it's useless to be on guard no matter how much we try. The only thing we can do is die!"

"That's right!" The elders of the academy do not take us seriously at all. Such a dangerous place, even if they, as cultivators, do not come, they still want us little martial artists to come down. "In my opinion, this must be the idea of that cultivator from the Myriad Sword Sect. Otherwise, the elders of the academy would never have let us throw our lives away!"

"Shut up!"

Senior Martial Brother Chen who spoke earlier shouted, "You dare to speak out against the experts of the Myriad Sword Sect? Do you not want to live?!"

"What are you afraid of!" It's true that the experts of the Myriad Sword Sect are terrifying, but right now, he's probably busy choosing his personal maid, so he doesn't have the time to pay attention to us! "

"That's right. Speaking of which, that expert from the Myriad Sword Sect is too arrogant. If he sees a woman, he can just make her his personal maid …" It's really a pity that that beautiful girl jumped down just like that. She definitely fell to her death! "

"Don't talk so much, hurry up and prepare to collect the blue flames. After completing the mission, hurry back!" Senior brother Chen said in a deep voice.

"I didn't expect that even the experts of the Myriad Sword Sect would be here. To be able to join a sect, one must be at least at the Danhai Realm. It seems that it will be difficult to get the Azure Flame this time."

Seeing that those people had already taken out jade bottles and were preparing to collect the tongues of flame, Lin Cheng no longer hesitated and quietly approached them. After that, he quickly circulated the Yuan Li in his body and displayed the Cloud Stepping Technique under his feet.

"Bang bang bang!"

The three of them were knocked out instantly by Lin City. By then, the remaining two people had already noticed the sneak attack and cried out in alarm, "Who is it …"

Lin Cheng didn't even give them time to react before he struck out one after another with his Fierce Demon Palm.

"Bang!" "Bam!"

The remaining two people didn't even have the strength to resist as they were knocked unconscious.

Lin City didn't try to kill them. They only removed the joints of these martial artists, so that they wouldn't be able to move their fingers even if they woke up.

Then, Lin City only left the thinnest martial artist to hang the others on a tree because he had just discovered that this thin martial artist seemed to be extremely nervous, constantly looking around. Carefully, he knew that this martial artist was very timid, making it easy to interrogate him.

"Ugh …"

The thin martial artist slowly woke up and found himself lying on the ground. He couldn't move his body, and besides his head, he couldn't move at all. But in his line of sight, there was a strange young boy, and he was immediately shocked, "You, who are you?"

Lin Cheng coldly stated, "Who I am is not important. What's important is why you want to invade my territory!"

"Your territory?"

The thin martial artist was startled. "That's impossible. It's impossible for anyone to survive in the Boundless Valley. This is a masterless land, how could it be your territory …"

After saying all that, he seemed to have thought of something and his expression changed drastically. His voice began to tremble, "You … you are … A transformed demon beast? "

"Humph!"

Lin Cheng coldly snorted, "Now I'm the one asking you, not you asking me! If you don't honestly answer my question, I will make you the same as your comrade, a cripple! "

Seeing that Lin Cheng did not deny it, the thin martial artist became more convinced that Lin City was the demon beast in human form. He had heard that when the high level demon beasts reached a certain level, they could take human form.

All the demonic beasts that could take human form were all powerful experts with great abilities. It was said that even ordinary cultivators did not dare to provoke them.

Thinking up to this point, he panicked, "This …" Senior, this junior definitely does not have any intention of offending you, but I was ordered to come down to collect the blue flames. I did not know that this is senior's territory, so I hope senior would forgive me! "

Lin Cheng coldly snorted: "You little warriors want to refine the azure fire? "It seems like this East Region Academy is only just in name."

The thin martial artist quickly said, "This junior does not dare to lie to Senior. Naturally, we do not have the ability to refine the Blue Flames. Thus, the mission that the Elders have given us is to take the Blue Flames with us and hand them over to Senior."

"That being the case, why didn't your elders come over personally and instead let you ants come down to die?" Lin Cheng coldly asked.

"Senior's reply …"

"It's not that I want to die, but the elders said that the Boundless Valley is an ancient battle ground. There is a strange power here, and once a Dan Hai warrior or warrior enters, they will be greatly suppressed. On the other hand, the warriors below Dan Sea Realm will not be affected, so the elders sent us here to collect the Azure Blue Flames …"

Lin Cheng couldn't help but be a little surprised. There was actually such a strange power in this deep valley that could suppress powerful warriors of the Danhai Realm and above?

This was the first time he had heard something like this!

However, he was relieved. No wonder why this deep valley was filled with all kinds of rare and precious herbs. However, he had been here for such a long time in his previous life and had never seen anyone come to pick those herbs.

It turned out that cultivators would be suppressed here, but martial artists were not. However, there were not only all kinds of ferocious beasts in the valley, but also some Demon Beasts. It was no difference if ordinary martial artists came here to die, so naturally no one would dare to come here.

"Looks like the legend is true. Only the supreme elders of that level are capable of such terrifying and transcendent means. Even after a long period of time has passed, such a strange power still remains!"

Lin Cheng's thoughts raced, "This way, those cultivators will not dare to come down so easily. That's why they sent students to collect the Azure Blue Flames …"

Thinking of this, he could not help but sneer. He was already prepared to leave, but now it seemed that the chances of him taking the blue flames were rather high.

"How many of you have come down?" Lin Cheng asked again.

"Except for the servants and martial artists who were staying in the academy, all the students at the Arterial Circulation Realm and above have come." The thin martial artist hurriedly replied.

Lin Cheng secretly let out a sigh of relief when he heard this. It seemed like Bamboo Hill didn't need to come down to take the risk. Lin City had personally experienced just how dangerous the deep valley was.

"The Ten Thousand Sword Sect also came?" Lin Cheng suddenly asked.

"Reporting to Senior, yes, several experts from the Myriad Sword Sect have come, and I've heard that one of them is the personal disciple of an elder of the Myriad Sword Sect." The thin martial artist firmly believed that Lin City was in the form of a demon beast. He panicked and didn't dare to hide anything from her.

Lin Chen nodded his head, looks like the experts are gathering at the top of this cliff, it was truly fortunate that the azure fire was in this Boundless Valley, if it was elsewhere, even if he cultivated to the pinnacle of the Pulse Rotation Stage, it would still be difficult for him to gain the upper hand under the encirclement of so many experts.

But now, these experts did not dare to come down easily. This was his chance!

"Senior … "Junior already told you everything I know. Senior, please forgive me …" The thin martial artist could not help but cautiously ask as he saw Lin Cheng frowning without saying a word.

"I can spare you, but I can't let you go now!" After Lin Cheng said this, under the fearful gaze of the thin martial artist, he slapped him unconscious and hung him on a tree.

Even if Lin Cheng did not kill these students, he would not let them go so easily. Otherwise, once the upper echelons knew that he was down there, they might descend.

Lin Cheng wasn't naive enough to think that these experts would be like this thin martial artist, treating him as a demon beast in the form of a human.

After taking care of these warriors, Lin City immediately entered into the green light. He knew that this was only the first batch, and there would be a large number of martial artists coming down. He had to make preparations in advance.
