With a loud noise, the energy cover covering the book was completely shattered and dissipated.

An ancient brown book appeared in Bai Yifeng's hands.

Advanced human-level martial arts: Explosive Fist.

After turning it over for a few times, Bai Yifeng sighed lightly and put the book helplessly back. Obviously, this was not what he wanted.

After five hours of searching, Bai Yifeng was also a little tired. In that morning, he smashed at least thirty energy covers of martial arts. The highest was the lower-level martial arts in the Earth level, but it was not suitable for him. He still wanted to try his luck.

Sitting on the ground, trying hard to absorb the Hunyuan Qi and recovering its consumption. The stronger the martial arts energy cover, the harder it is to break. These five hours almost exhausted all the Hunyuan Qi in his Hunyuan body.

After nearly an hour of recovery, Bai Yifeng also opened his eyes. Although he had not fully recovered, he had also recovered five or six levels.

He stood up and shuttled between the bookshelf again. Suddenly, Bai Yifeng's body paused, and a strange feeling breeded, as if attracting him to take something.

His right hand couldn't help but grab the middle level of a bookshelf.

Bang!

With the loud bang, Bai Yifeng took two steps back due to shock.

After frowned slightly, he looked at the technique that shocked him with interest.

His right foot suddenly stepped towards the floor, and his body shot out. At the same time, a layer of white light was covered with his right hand, and he slapped the technique sharply again.

boom!

With all his strength, the energy cover only cracked a small crack, and the rebound force caused Bai Yifeng to retreat a few steps, and a sweet throat and blood from the corners of his mouth were overflowing.

Old Dong and Old Mu stood in the yard, both of them were looking at the small building. After a long time, Old Mu murmured: "I was actually hit by that kid, but it is unknown whether it can succeed..."

After erasing the blood from the corner of his mouth, Bai Yifeng took a few deep breaths, and a solemn look surged on his face.

He took a strong breath, and the Hunyuan Qi in his body surged along the specific tendons and veins. The milky white light of his hands appeared again, smashing towards the energy cover.

"Xuanyuan Palm"

The two palms hit the light yellow energy cover heavily, and the crack spread a little, but it still did not break.

Bai Yifeng's chest was shaken tightly, and he spurted out a mouthful of blood.

"Sure enough, although this kid is very talented, his cultivation is too weak. He still has to break the energy cover of the advanced earth level." Old Mu looked towards Xiaolou and said with some regret.

The cold old man beside him also looked towards Xiaolou and said lightly: "I think he can get it."

"Huh?" Old Mu turned his head in surprise and looked at the old friend who had known him for decades and asked, "How can I see it?"

"Let's watch."

After hearing Mr. Dong's extremely perfunctory answer, Mr. Mu had to smile and turned to look at the little building, but he looked at Bai Yifeng a little higher.

He has known Mr. Dong for more than 40 years. This guy has always been cold and cold. Even if he is to him, he rarely speaks. He didn't expect that he would speak for a boy today and give him a good evaluation, which is extremely strange.

While gasping in a mess, Bai Yifeng narrowed his eyes and stared at the energy cover with a few more cracks. He was not in a hurry to continue attacking, but sat down directly, absorbing the remaining medicine in his body, and recovering his injuries from the shock.

An hour later, Bai Yifeng stood up again, retreated two meters, narrowed his eyes into a slit, and looked coldly at the energy cover with several cracks, looking for the weakest defense.

Suddenly, his right foot thrust the ground suddenly, flashed towards the bookshelf, and said lowly: "Xuanyuan Palm!"

"boom."

The moment the palm collided with the center of the crack on the energy cover, a huge sound came out. After two lessons, Bai Yifeng hurriedly used the Hunyuan Qi to defend himself. Although he was still shocked a few steps away and there was another sweetness in his throat, it was undoubtedly much better than the previous two times.

The number of cracks has not increased, but it has expanded a lot.

After carefully examining the energy cover, Bai Yifeng sighed helplessly. In this case, he would probably have to attack at least dozens of times before he could barely break the energy cover.

Just when I was hesitating in my heart whether to give up, the faint sound of the colorful phoenix egg suddenly appeared in my mind.

"Don't be afraid of trouble, be sure to get it."

After leaving a sentence, no matter how Bai Yifeng said, the colorful phoenix egg did not reply again.

Bai Yifeng patted his forehead helplessly, took a few deep breaths, and flashed out again like thunder, slapped out with one palm again...

The sun sets.

Wiping the sweat off his forehead with his sleeve and looking at the energy cover covered with cracks, a curve appeared on the corner of Bai Yifeng's mouth.

Finally, it's going to succeed.

After soothing the excitement, the Hunyuan energy surged in my palm...

"Bang."

As the palm of his strength fell, a huge sound rang out, and the cracked energy cover finally burst.

The moment the energy cover burst, a strong aftermath of energy also came suddenly. Under almost exhaustion, Bai Yifeng was shocked and fell to the ground without any precautions.

Bai Yifeng also smiled as he raised his head in embarrassment and looked at the yellow book that had no energy cover.

He slowly stood up on the ground and grabbed the book into his hand.

Advanced skills of the Earth-level: Rapid Thunder Death!

The corners of his mouth were raised, and he held it tightly in his hand with satisfaction, and then he slowly walked downstairs.

After stepping out of the gate of the Treasure Pavilion, a figure also came over and asked with a low smile: "Why have you used it for so long? How are you doing?"

Looking at Wancheng with a smile, Bai Yifeng raised the yellow book in his hand.

After looking at the yellow book in Bai Yifeng's hand, Wan Cheng thought quickly in his mind. After a moment, he laughed a few times and said with great satisfaction: "Good boy, you have broken the energy cover of the advanced earth-level martial arts. Not bad, not bad!"

After Bai Yifeng came out, two unfathomable old men did not appear, but Wancheng still said respectfully in the direction of Xiaolou: "Old Mu, Old Dong, let's go first."

After Wancheng said that, the gate of the small building was closed by itself.

As the father and son left, two figures also landed in front of the small building. The old man called Old Old, smiled rare and said, "Old Man Mu, I'm right."

The hot old man Mu nodded helplessly and replied: "You old ghost still have a vicious eye."

Walking on the stone road back to the yard, Bai Yifeng asked curiously: "What are the two old men guarding the treasure pavilion? Why do my father value them so much?"

Wan Cheng explained: "The one who makes people feel cold is Dong Lao and Dong Bai, who are from the same family as your mother, and one is Wu Duan Yuanling, and the other is Mu Lao and Mu Cheng, who is a little weaker than Dong Lao, and is the fourth Duan Yuanling. They guard the Treasure Pavilion and also guard the City Lord's Mansion. Before I became the City Lord, they would be here. If it weren't for the City Lord's Mansion facing life and death, otherwise, even I would not have the right to order them to do anything."
