"Bang ......"

The fist mark hit the wooden wall on the right, causing it to ripple again and rattle.

However, the wooden wall soon regained its calm and was unscathed.

Han Feng put away his fists, a little disappointed, and didn't know how to break into this secret room for a while.

"Perhaps, it is really only possible to get out if you understand those runes thoroughly. Han Feng thought secretly.

He raised his hand and pinched the trick, his eyebrows scorching, releasing a tumbling soul power, dividing thousands of wisps out, like needles, extremely slender, constantly piercing those runes, trying to merge with them so that he could comprehend the mysteries within.

However, as soon as his soul power pierced those runes, they immediately collapsed, so that his soul power could not merge with those runes at all, and he could never capture their rune veins.

Han Feng tried dozens of times to no avail, so he could only give up temporarily.

He thought about it carefully, changed the method, spread out his soul power, and covered these runes like soft water, and observed their runes up close.

He was secretly happy, and he did see the veins of these runes, but they were different and varied, and it was impossible to generalize the rules at all, which was extremely difficult.

"There is a huge amount of information, and it is impossible to decipher it at all!" Han Feng worried.

Han Feng sighed and gave up this method, if he continued to use this method, he would definitely consume himself to death!

Taking 10,000 steps back, even if he can see through the mystery with this method, he doesn't know that it is the Year of the Monkey, and at that time, I am afraid that he himself will decay.

He retracted his soul power and didn't waste any more time.

"What should I do?" Han Feng stood in front of the wooden wall, wandering, thinking hard.

Time passed quickly, and another half an hour passed, and Han Feng still didn't come up with any good solutions.

He returned to the middle area, sat down, and decided to break through the formation confinement in the secret room first and restore his mana.

In the process of breaking through the middle stage of dragon descent before, he was able to release some of his mana, and it was obvious that it was still effective to forcibly break through the confinement with brute force.

He has always been a resolute character, and when he thought of this, he immediately began to implement it.

Han Feng immersed himself in his dantian, looked inside, and found that the Heavenly Dao Jin Dan was still imprisoned in place, only a little mana seeped out, and almost nine percent of the mana was blocked in the Jin Dan.

Chains of pale cyan light bound to his Heavenly Dao Golden Pill, firmly locking its operation.

He cast the Soul Alchemy Vajra Technique, mobilizing the power in his body to continuously impact those pale cyan rays.

But this cyan light was indestructible, and no matter how much he attacked, it would not help.

Han Feng was secretly anxious, his hands were closed, his ten fingers were linked, and those spirit refining powers suddenly turned into five-clawed golden dragons, biting into the pale cyan rays one after another, but they couldn't tear them apart.

It was just a little bit of a loss of them, and they were soon replenished by the runes that had infiltrated from the outside world, and they were repaired again, shining brightly and with brilliance.

Han Feng looked at all this and felt helpless, but naturally he would not give up, and continued to urge the five-clawed golden dragon to attack these pale cyan rays.

After a few rounds, he gradually discovered that these pale cyan rays were specific runes, forming a group of brilliant runes, wrapping the Heavenly Dao Jindan like cotton cloth, sealing its connection with the outside world, so it could not release mana.

Han Feng's eyebrows glowed, and his soul power gushed out, not scattered everywhere, but gathered in the dantian, turning into a ball of water, gently covering this talisman, and seriously contemplating.

He immersed himself in it and slowly fell into a state of selflessness.

Time seemed to have lost its meaning at this moment, and Han Feng was completely unaware of the passage of time.

Seven days and seven nights, just like this, Han Feng's understanding gradually deepened, and his whole body was actually emitting bursts of rune light on its own, one by one runes appeared, the five elements of yin and yang, the gossip of Xuanmen, all kinds of runes were staged in turn, and so on.

Suddenly, these runes disappeared in an instant, and suddenly a dazzling ball of light appeared, the whole body was pale cyan, and the runes on the surface flickered, and the forms were different, which were similar to the runes in the secret room.

The tiny runes floating in the air seemed to be summoned, and they were immediately attracted by this ball of light, and like mosquitoes seeing blood, they rushed one after another, surrounded it, and rushed into it like moths to fire, and disappeared in an instant.

With the nourishment of these runes, the ball of light became stronger and stronger, and its brightness was extremely high, reflecting the entire secret room, and even Han Feng's body was transmitted, faintly showing his muscles, bones, veins, and internal organs.

At this moment, Han Feng opened his eyes, crossed his hands, formed a special seal, pressed it to his chest, and the ball of light behind him immediately shot back, submerged into his body, shrunk at the first time, entered his dantian, and then expanded back, enveloping the Heavenly Dao Golden Pill from the periphery.

The ball of light rotated, as if it was unlocking, unscrewing the talisman that originally sealed the Heavenly Dao Golden Pill, and the two energies hedged against each other, and with a muffled bang, both of them were annihilated and disappeared without a trace.

The Heavenly Dao Golden Pill suddenly released a thousand zhang of golden light, and bursts of cyan Heavenly Dao aura diffused, spreading out from the inside out, flooding the entire secret room.

Those tiny runes that were invisible to the naked eye were shocked, and they rolled up one after another, colliding with these heavenly Dao breaths, inspiring a series of sparks, which were extremely bright.

Han Feng's mind moved, and the runes on his body surface flashed, and as the mana of his Heavenly Dao Golden Pill seeped out, they expanded together, turning into an existence that was roughly the same as these runes, but its essence was completely different, and it swept through the runes in the secret room like the scorching sun melting ice and snow.

These runes were the unique aura emitted by the cyan wood strips, and at this moment, they were retreating, and when Han Feng's rune light power came to the cyan wood strips, they immediately dissolved, one after the other, leaving holes of different shades.

Han Feng laughed, the gloomy look on his face was swept away, he stood up suddenly, raised his feet and walked to the wooden wall on the left, put his hands together, grasped the magic trick, and combined the three powers of soul power, physical strength and mana, condensed the power of the mighty special rune light, hitting the wooden wall like a wave, and in a few breaths, it melted into a hole the size of a zhang, communicating with another secret room.

Han Feng frowned, a little puzzled, secretly thinking that there are many secret rooms here, how long and what month will it take to crack this?!

He put away his suspicions, walked quickly through the hole, and really entered another secret room that was also the size of a hundred zhang.

Moreover, this secret room was also surrounded by cyan wooden strips, and it was also filled with endless runes, but under the sweep of the special rune light power released by Han Feng, there was no power to stop it, and it quickly melted and dissipated.
