Qin Feng rode the teleportation array and arrived at the twentieth floor.【】

At this moment, he was in a cave, and in front of him was a black cave wall as smooth as a mirror.

"Let the cave wall make thirteen bell-like sounds in succession, and you will pass."

Information about this level emerged in Qin Feng's mind.

"Is it that simple?"

Qin Feng was shocked.

However, when he thought about it calmly, he realized that this matter was definitely not that simple.

Being able to serve as the twenty-first level is enough to prove that the difficulty of this level is by no means lower than the levels he has experienced.

Qin Feng used his Tianpu eyes to detect it, but found nothing.

Qin Feng opened his lunge, gathered strength with his right fist, and suddenly punched out.

"Boom."

"Bang."

An explosion resounded, but what Qin Feng didn't expect was that the wall was intact, but he was blown away. Moreover, even then, the wall did not make a bell-like sound.

It can be seen that this level is not easy to pass.

Qin Feng used his breathing skills to recover from the minor injuries he had suffered previously.

Immediately, he looked solemnly at the smooth cave wall in front of him.

"This stone wall is indeed not simple. Although I did not use all my strength just now, but my strength was not small, I was unable to hit it. Sure enough, there are some tricks."

Qin Feng pulled out the Ghost Dragon Sword, unfolded it in a killing sword style, raised the sword and slashed down, touching the cave wall.

"when."

A bell-like sound sounded from the cave wall, but the next moment, a force bounced off the cave wall, which was exactly the same as the sword power produced by Qin Feng.

Qin Feng was on guard and used his energy to resist, but he was still knocked out. Qi and blood in his body were churning, and all his internal organs were damaged.

"It's amazing."

Qin Feng covered his chest and looked at the cave wall, his heart extremely heavy.

This cave wall is so weird that it can bounce back all the energy that the warriors have blessed on it.

Moreover, he just performed a powerful sword move and let it ring once, but to break this level, he needs to make thirteen consecutive rings.

Thirteen rings means using powerful force to bombard the cave wall for thirteen times in a row. Not to mention whether one's own physical strength and profound energy can withstand it, but more importantly, who can withstand the thirteen force rebounds.

Qin Feng Yungong adjusted his breath and continued to attack the cave wall. If he wanted to find out the doorway, he had to keep trying, exploring and summarizing in the attempts.

He kept attacking the cave wall. Every time his power rebounded, Qin Feng specifically dodged it. However, after dozens of attempts, the cave wall always only made a sound, and sometimes he failed to dodge and was hit. He was seriously injured.

.

However, his efforts were not in vain. After hundreds of attempts and three days, he finally discovered the rules and mastered the mechanism of energy rebound after each attack landed on the cave wall.

Time and location.

In this way, he can avoid the energy rebound in time after attacking the cave wall.

"call."

After Qin Feng finished adjusting his breath, his eyes gleamed with energy, and he suddenly attacked the cave wall.

Dangdangdang...

Qin Feng used his sword skills and stabbed with lightning speed, but when he left five sounds on the cave wall, suddenly, the sounds produced powerful sound waves, which bombarded Qin Feng's Niwan Palace.

Unexpectedly, Qin Feng was attacked immediately. He screamed and flew backwards as if he had been hit hard.

In the end, his body hit the cave wall hard, with several cracks appearing on it, and Qin Feng's appearance was even more miserable, with bleeding from seven holes and a pale complexion.

"I didn't expect...this cave wall could be so attacking!"

Qin Feng looked ferocious, endured the severe pain, forced himself to sit cross-legged, and used Qigong to regulate his breathing. With the powerful recovery ability of Shengsheng Xuanqi, his injuries were improving rapidly.

At the same time, I was also thinking about how to deal with the sonic impact from the cave wall.

"After the fifth ring, the rebound is no longer the warrior's energy, but converted into sound waves to carry out soul attacks, and there is no delay, it is instant!"

"The sonic attack just now has probably reached the level of a small heaven, and I am also a small heaven now, so I should be able to withstand it!"

Qin Feng took the lead in using his powerful mental power to form a light film to protect his Niwan Palace. In addition, he condensed sword energy and mysterious energy into a protective shield to protect his body.

After making all these preparations, Qin Feng immediately launched an attack.

Dangdangdangdangdang...

Qin Feng drew out his sword and stabbed continuously, and a sound like a bell sounded from the cave wall. Just as Qin Feng expected, with the mental power of his little heavenly position, he was indeed able to withstand the fifth and sixth bells.

The seventh ring, but after the eighth ring, the sonic attack instantly increased to a level that exceeded Qin Feng's recognition range. Even if he swept out, he would vomit blood.

"hateful."

Qin Feng got up and looked at the black cave wall. He was so angry that his teeth itched. He did not expect that the power of this sound wave would become stronger and it had already reached the early stage of Zhongtian.

"Looks like I need to improve my mental strength again."

Even with his mental strength and profound energy, he couldn't withstand the sonic impact of the eighth or the ninth or tenth ring.

Only by improving your mental strength can you have hope.

After understanding this, Qin Feng sat cross-legged and began to practice the 'Heavenly Soul Art'.

Everything became silent as Qin Feng practiced quietly.

As the days passed, Qin Feng's mental power continued to increase.

Two months later, suddenly, a powerful golden energy surged out of the Life Soul Pearl. On this energy, Qin Feng smelled a familiar smell. He understood that this must be extracted and refined from Sima Changfeng.

Essence and blood.

Originally, he thought that all the essence and blood had been completely absorbed by the Life Soul Pearl, but he didn't expect that there was still some retention.

In any case, this is a great thing for Qin Feng. The essence and blood energy of a strong man in the Divine Soul Realm is no small matter. After refining and absorbing it, Qin Feng's own soul realm has directly impacted the middle stage of the Small Heaven Realm.

Early stage of the middle heaven position.

His mental strength has been greatly improved, and Qin Feng is even more confident.

After getting ready, he stabbed again with his sword.

Bang bang bang bang bang...

Dangdangdang...

The ear-splitting sound of the bell kept ringing. Qin Feng gritted his teeth and waved the Ghost Dragon Sword against the violent impact of the sound waves. Finally, after a few seconds, thirteen sounds were heard on the cave wall.

"call."

After doing all this, Qin Feng stood with his sword in hand, a smile on his extremely pale face.

"Congratulations on passing the test, please receive the Holy Baptism."

"Baptism?"

Qin Feng was shocked and didn't know what this holy baptism was, but he soon found out.

What I saw was that as soon as the other party finished speaking, there was a ray of light shining down.
Chapter completed!
