Hearing what Ye Xiao said, Zhao Yufei also began to search for something that can provide enough energy to this barrier to continue its momentum from thousands of years ago till now.

They both searched for quite a while but did not find anything.

"What should we do now?" Zhao Yufei looked at the young man in front of him. This young man, from the moment she saw him, has always surprised her with everything he does.

Those memories were still fresh in her mind when all the stone statues chased after Ye Xiao because he used himself as a bait in order to open the iron door of the room they were currently in.

She didn't know how but she believed that Ye Xiao will certainly find a solution on how to crack the barrier that protects the wall.

They both were curious about what was behind the strange wall that required a barrier of this level to protect it.

Ye Xiao was silent for a moment then looked at the barrier that was protecting the strange wall.

"I think I should try that thing. Let's see what will happen." Ye Xiao thought and said, "Let me give it a try."

Ye Xiao came near the barrier and put his hands on it and started to circulate the First Layer of Nine Dragon Universal Circulation Technique.

"What is he doing?" Zhao Yufei was confused when she saw Ye Xiao putting his hand on the barrier. She doesn't understand what Ye Xiao was trying to do now, but still, she was staring him very carefully. She did not want to miss anything. She had a strong feeling that Ye Xiao will again do something that will surprise her.

"Devour! " Ye Xiao shouted in his heart.

"Roar!"

A dragon's roar echoed in the sea of his consciousness and suddenly all the energy from the barrier begun to pour in his body like a flood.

"Aah!"

He groaned in pain. There was too much energy there and if this continued for a long time, his body will surely explode.

"Ye Xiao, what happened?" Zhao Yufei got scared due to Ye Xiao's painful scream. She hurriedly made her way to him.

"Nothing, You stand there, don't come here." Ye Xiao endured the pain and said with great difficulty.

He was currently circulating the First layer of the Nine Dragon Universal Circulation Technique and trying to absorb the energy coming into his body.

"BOOM!!"

Third Stage of Qi Condensation Realm

After some time he breakthrough once again and reached the Third Stage of Qi Condensation Realm from the Second Stage of Qi Condensation Realm.

Seeing Ye Xiao breaking through in this kind of situation, Zhao Yufei could not help but be astonished.

"How can it be? He brokethrough to Third Stage of Qi Condensation Realm just now. He was still groaning in pain a while ago but now..."

Ye Xiao was constantly devouring the energy and when he reached the peak of Third Stage of the Qi Condensation Realm, he lifted his hand from the barrier.

"Too much energy. After devouring so much, there is still some energy left." Ye Xiao thought.

"Ye Xiao, are you alright?" Zhao Yufei asked worriedly when she saw Ye Xiao lifting his hand off from the barrier.

"Hmm, I'm fine. Don't worry." Ye Xiao smiled. For sme reason, he felt warmth in his heart when he saw Zhao Yufei's worry for him.

From the very start, he never felt the care of others for him. One day, Fifth Elder Ye Fan of the Silver Moon Sect came and took him in. That was the first time when he felt warmth in his heart. He took Fifth Elder Ye Fan as his father but after the death of the Fifth Elder Ye Fan, he was once again abandoned.

Now seeing Zhao Yufei worrying about him, he really felt warmth and smiled looking at her from the bottom of his heart.

When Zhao Yufei saw Ye Xiao smiling at her sweetly, she felt her heart throbbing and blushed. Her fair white cheeks turned slightly red.

"You, What happened to you at that time. You were groaning in pain and suddenly brokethrough to the next stage of your cultivation realm." Zhao Yufei hurriedly turned around and asked while looking at the wall being protected by the barrier.

She, at this time, for an unknown reason, did not dare to look at Ye Xiao's eyes directly.

"It's nothing. I was just trying to see if I can break this barrier with a secret method or not. I am currently weak and unable to use that secret technique. So when I forcefully used it, it backfired and caused me some pain." Ye Xiao made a random answer and give it to Zhao Yufei. After all, he could not say that he has the ability to devour anything that has energy.

Ye Xiao did not continue to devour the energy from the barrier because he was levelling up too fast. Although his foundation was very solid but cultivating too fast has its own setbacks.

"Well, I found out where that thing is, that is constantly providing energy to this barrier." Ye Xiao smiled. When he was devouring the energy from the barrier, he noticed from where these large amount of energy was coming from. And that was the source of barrier's energy.

"Where?" Hearing Ye Xiao say that he has already found out where the source of energy is, her eyes lit up. It is needed to know that the energy was continuously pouring into the barrier to strengthen it for thousands of years. That thing definitely is a treasure.

"It is inside that wall. It is because of that thing, the wall looked so strange." Ye Xiao pointed at the wall.

"So that's how it is. No wonder, even after searching for a long time, we didn't manage to find anything here." Zhao Yufei suddenly comes to a realisation.

"We have to first break this barrier. But how?" Zhao Yufei once again began to think for a solution.
