"Wait for me to return with peace of mind!" Zhao Chen turned to leave, leaving a word with a relaxed expression, and his and Yan Rutian's figures disappeared in place.

With Zhao Chen's departure, the two people who stood in place were left stunned.

"Senior Gu, do you think I should report this matter to my father?" asked Mei'er a little confused.

Gu Chengfeng pondered for a moment, "Now that we are all in the same boat, this matter should be told to the emperor, perhaps...... The emperor knows more about the Houshan Spirit Cave. ”

"Also, my father must know more than we do. Mei'er nodded and muttered in a low voice.

"That'...... Senior Gu thinks Senior Zhao can come back from the Spirit Cave in the back mountain?" Although Mei'er said in her heart that she believed that Zhao Chen would definitely be able to come back, she still asked with a little worry.

This time, Gu Chengfeng did not hesitate, and said with great certainty: "There is nothing in this world that the master cannot do, even the sect master of the Martial Emperor realm can be killed, what can the mountain spirit cave do to him?"

This is Gu Chengfeng's absolute trust in Zhao Chen!

"I think so too!" Gu Chengfeng's words made Mei'er feel deeply and couldn't help but resonate!

At the same time, Zhao Chen took Yan Rutian on the way to the Spirit Cave of Xianghou Mountain.

The mountain behind the Demon Fire Sect is also the only place in the entire Demon Fire Sect that has not been affected by that battle, and it is not an exaggeration to call it a ruin by the Demon Fire Sect at this time. "Such a fierce battle has not affected this place, it seems that this place is really not as simple as they said, and there is a good chance that the Demon Gate is also here, but it's a pity...... Why didn't I discover this place earlier?" It was also strange to say, Zhao Chen's perception of the power of heaven and earth

He was particularly perceptive, but he didn't notice the place at first.

"In this way, this should be inseparable from the sect master, after his death, this place gives me a completely different feeling. Zhao Chen thought about it carefully and finally determined the reason.

Zhao Chen and Yan Rutian looked at the incomparably strange back mountain in front of them, and walked in without hesitation.

"I don't know where the spiritual cave in the sect master's mouth is, that place is the key to this trip. Entering the back mountain, Zhao Chen did not feel any discomfort, but this did not make Zhao Chen relax his vigilance.

The top priority is to find the Spirit Cave first, in Zhao Chen's opinion, not only Yan Tianyu and a few people are over there, but the Demon Gate is also near the Spirit Cave.

"Senior Zhao, this place is not as terrifying as they say. Unlike Zhao Chen, Yan Rutian at this time completely relaxed his vigilance.

Zhao Chen shook his head and reminded: "No! this place is not as simple as you think, they are right!"

Immediately, Zhao Chen pointed to the grass next to him, "What do you see is that?"

"Bones?" Yan Rutian said with a frown as he recognized the origin of the pile of white bones in the grass at a glance.

"It would take at least ten people to have so many bones. As he spoke, Zhao Chen slowly approached the pile of bones, and then felt a great sense of resentment and fear.

Zhao Chen looked up at Yan Rutian beside him and asked, "Do you feel it?"

"What?" Yan Rutian only had a bunch of white bones in his eyes, and he didn't feel anything else, but he was a little inexplicable when he was asked by Zhao Chen.

"Take a closer look to see if there is a trace of black line on these white bones......" Zhao Chen said, pointing to the black lines on the white bones.

Sure enough, being reminded by Zhao Chen, Yan Rutian really found a trace of black line on the white bones, and there was it on every white bone.

"No, there are still lines on this?" Zhao Chen took a closer look, there were still small lines hidden between the black threads of those white bones, but this pattern made Zhao Chen feel very familiar, and he couldn't help but fall into deep thought.

After some contemplation, Zhao Chen finally remembered where he had seen these lines before, "I said why is it so familiar, it turned out that this is the pattern on the miniature version of the Demon Gate after a long time." ”

"So...... The death of these people has nothing to do with the Demon Gate?" Zhao Chen guessed in his heart.

Zhao Chen stared at the white bones in the grass again, but he really didn't find anything, and then continued to walk towards the mountain with Yan Rutian.

Along the way, Zhao Chen found a lot of bones, and the situation was similar to the first time he found it, which made Zhao Chen even more sure that the deaths of these people were inseparable from the Demon Gate.

"There are so many white bones, at least a thousand people must have died here, right?" Yan Rutian finally raised his vigilance, where is this back mountain, it is almost like a mass grave, and bones can be seen everywhere.

"So this place is not simple, these people all died very miserably, and the resentment on the bones is very heavy...... "Zhao Chen and they didn't encounter any danger when they entered the back mountain, and they often had a trace of expectation for unknown things.

However, just when Zhao Chen and the others were halfway through the back mountain, a sudden change occurred, a yin wind suddenly blew, the sky instantly darkened, and the originally sparse woods suddenly became lush, instantly blocking all the light.

"Be careful, danger is coming!" Zhao Chen cheered up and reminded Yan Rutian beside him.

Although there was no light at this time, Zhao Chen could still see everything in front of him clearly.

I saw a bright light suddenly appear in the darkness, and as time passed, these bright lights became more and more numerous.

It turned out that the bright light that appeared just now were all tiny insects, and if it weren't for the flames on their bodies, it would be difficult to detect them with the naked eye.

"Hmm, Senior Zhao, what are these things, why does the light they emit make me feel so uncomfortable?" Yan Rutian only felt that his heart was unconsciously full of fear, and subconsciously took a few steps back.

Looking at Zhao Chen again, he didn't receive any influence, his eyes were as sharp as a blade, with a hint of grief and indignation, and he said in a deep voice: "These are Heavenly Demon Insects, which are characteristic of the Heavenly Demon Clan, and they specialize in absorbing the soul and power of human beings......

Zhao Chen recognized their origin at the first glance when he saw these insects, and it was precisely because of this that Zhao Chen felt angry.

Zhao Chen finally knew the reason for these people who died in the back mountain, no wonder they had so much resentment and fear, and those who were contaminated by the Heavenly Demon Worm had to bear the pain of devouring their hearts......

"With so many Heavenly Demon Worms, there must be at least tens of thousands of deaths here, right?" Zhao Chen looked at the dense Heavenly Demon Worms in front of him, and said extremely angrily.

"Senior Zhao, what is the Heavenly Demon Worm?" Yan Rutian asked in confusion.

Zhao Chen couldn't explain clearly to Yan Rutian for a while, "You just need to know that this thing is the most evil thing." ”

"Isn't that rain going to be dangerous now?" Yan Rutian frowned and asked nervously. "No, they are all people brought by the sect master himself, and they can be said to be the prey of the sect master, and the demon insects will not touch them these days. Zhao Chen said categorically.
