The green sword hanging on Ye Yan's chest floated up. The green light emanated from the scarf and shot towards the surrounding walls. Then it disappeared into the wall. Although there was no change on the surface, it actually strengthened the wall and at the same time strengthened the way to hide the breath here.

At this time, Liu Yiyi was immersed in the refining of the Martial Saint's heart, and she was unaware of all this happening.

"It's already done!" Qing Ling's voice sounded in Ye Yan's mind.

Ye Yan nodded, and after seeing Qing Ling take action, he felt relieved.

A large amount of blue light emanated from the heart of the Martial Saint, and the wind-attribute energy in the room became more and more intense. Then, the heart of the Martial Saint flew up from Liu Yiyi's hand, and the body slowly rotated in Liu Yiyi's chest. The color light and the true energy emitted from Liu Yiyi's body were completely merged together.

"It's almost done, it's going to succeed!" Qing Ling shouted excitedly.

Ye Yan's face was full of joy. Yiyi was about to succeed, which means that it would not take long to become a strong man at the level of Martial Saint. He couldn't help but be happy for Liu Yiyi.

However, at this time, the change produced a strong blue light that suddenly burst out from the heart of the Martial Saint. Suddenly, the wind-attribute energy in the room became violent. ▲Yiyi's face also showed a look of pain.

"What's going on? Qing Ling, what's going on!" Ye Yan was anxious and asked loudly.

"Liu Yiyi's strength is still too weak to bear the heart of the Martial Saint. That's why this happened!" Qing Ling replied.

"What should I do? Didn't you say there was no problem before?" Ye Yan asked anxiously.

"I didn't expect such a situation to happen. Yiyi's preparations were already very sufficient, and the Martial Saint Heart completely accepted her. Logically, such a problem should not occur!" Qing Ling was also a little confused about the situation. After all, he was just an introduction. Although he was knowledgeable, he didn't know everything. He just knew a lot when he was following the Qing Emperor.

"Stop talking about these useless things? How can we solve this situation?" Ye Yan was so anxious.

"I have no choice but to do anything. We can't help her, we can only overcome it by relying on her own!" Qing Ling said helplessly.

"Damn it!" Ye Yan cursed. Seeing Liu Yiyi's face full of pain, big sweat dripped from her face, Ye Yan felt very distressed. If Liu Yiyi had a mysterious accident, he would never forgive him for his whole life.

The blue light emitted from the heart of the Martial Saint is getting more and more intense. Yiyi seems to be getting more and more painful. She seems to realize that something is wrong. However, she still did not give up, and Yinya clenched and persisted hard.

With a "touch", a big hole was cracked in the window of the room. The rich wind-attribute energy in the room seemed to have found a catharsis port, and it rushed out quickly.

"Oh no, I forgot to strengthen the window. Ye Yan, block that hole quickly!" Qing Ling shouted.

Ye Yan did not dare to be negligent, so he hurried to the window. He used a wooden board to block the hole with such a strong wind-attribute energy in the north, which would definitely attract others' attention. If so many strong people in the Northern Academy knew about it and deliberately came to mess with the heart of the Martial Saint, it would be bad. Now, I can only pray that the wind-attribute energy that had just leaked was not discovered by anyone. Otherwise, the love would be bad. Ye Yan kept complaining to Qing Ling in his heart. Qing Ling knew that he had done something wrong and kept apologizing to Ye Yan.

The pain on Liu Yiyi's face was relieved immediately. Not long after, her face became positive. When the heart of the Martial Saint floating on her chest began to slowly move towards her.

Ye Yan felt relieved when he saw this scene.

"Ye Yan, where did you get this Martial Saint Heart?" Mu Sheng asked.

"In the ancient battlefield of the Six Saints, it should be left by the wind-attributed martial saint He Yiming. It's just that I happened to get it. Grandpa Xiaomu, you can keep it a secret for me!" Ye Yan said.

Mu Sheng nodded.

Soon, the heart of the Martial Saint touched Liu Yiyi's chest. Under the influence of a large amount of wind-attribute energy, it flashed and went directly into Liu Yiyi's chest, and merged with her whole body.

"It's successful, Liu Yiyi has successfully merged with the heart of the Martial Saint." Qing Ling's voice sounded in Ye Yan's mind again.

Ye Yan nodded and said nothing.

Then, a large amount of wind-attribute energy in the room rushed towards Liu Yiyi. Her cultivation level immediately increased. From the middle stage of the Great Martial Arts, she broke through to the late stage of the Great Martial Arts, and along the way, she broke through the peak of the Great Martial Arts. She crossed the bottleneck of the Great Martial Arts to the Martial Arts, and broke through to the early stage of the Martial Arts, the middle stage, and late stages, and continued to stabilize to the peak of the Martial Arts.

It was not until this time that Feng Yu took back the hand that covered Liu Yiyi's head.

"Hu!" After letting out a long breath, Feng Yu seemed very tired.

"What's wrong?" Mu Sheng couldn't help asking with concern.

"The energy left over from the powerful martial saints of the ancient times is too huge. I used a lot of effort to suppress it. Otherwise, this little girl would probably have to break through to the Martial Emperor. But in that case, she would have to spend decades laying a solid foundation. If she wanted to break through to the Martial Emperor, she would probably have to spend more time!" Feng Yu replied.

After hearing Feng Yu's words, Ye Yan couldn't help but feel a little grateful to her. Everyone knows that if the breakthrough is too fast, it will cause unstable foundations. It will be very difficult to break through to a deeper level, and it may also be insane and endanger life. Feng Yu's move just now undoubtedly eliminated Liu Yiyi's future troubles.

"Why, I saw the good seedlings and got the idea of ​​collecting disciples?" Mu Sheng said with a smile.

"I think so! But I don't know if they want it or not!" Feng Yu also said with a smile.

Ye Yan heard some of the names. This old woman looked very powerful. If she could accept Liu Yiyi as her disciple, Liu Yiyi would definitely be able to go further and better in the future.
