Han Feng's soul power has been shrouded in all directions, heaven and earth, everything is under his surveillance, only to see that those true demon qi is very slippery, and in a flash, it disappears into the depths of the earth and disappears, and that layer of mysterious diaphragm resurfaces at some point, preventing him from exploring at a deeper level.

Han Feng thought for a moment, then suddenly rushed down, the light on his body flickering, directly through the swamp, deep into it, and followed closely.

Those sealing wrestlers didn't know what to do for a while, and they rioted for a while, but they quickly regained their composure, and they exited the swamp in a uniform manner, staying outside, as if waiting for Han Feng's return.

Soon, Han Feng went to a depth of more than 1,000 zhang, and that layer of diaphragm blocked his way, he didn't say a word, he pinched his fist mark and attacked fiercely, but after fighting for a while, he couldn't break it.

He raised his hand and took out the Sky Breaking Sword in the storage ring, without delaying time, it was directly a sword split, and with a snort, it actually cut a hole, which could accommodate one person in and out.

He immediately turned into a streamer and rushed down like lightning.

It's still muddy and muddy, and all kinds of smells are permeating, and if a mortal comes here, he will definitely be nauseated, and may even faint.

Han Feng's body was surrounded by light, naturally there were no such problems, his body was like a swimming fish, and he dived down rapidly, the speed was fast, and after a few breaths, he went deep into the bottom of thousands of zhang.

At this moment, wisps of black qi suddenly emerged from all directions, turning into thousands of black long knives, stabbing straight ahead, making him have no way to retreat.

Han Feng sneered, and the Broken Heaven Sword in his hand shook, and the sword qi was like silk, rising into the sky suddenly, successfully resisting the attacks of these long knives like the tip of a needle against Mai Mang.

"Dingding......

The sound of a rain hitting bananas spread, and all the black long knives shattered, turning into wisps of black qi again, but they couldn't escape, they were entangled by the sword qi like silk threads, pulled to Han Feng's side, and were once again swallowed by the white light emitted by his body.

Han Feng's soul power was displayed, spreading to a radius of thousands of zhang, and he went around in a big circle, but he couldn't find the source of these demonic qi, so he could only continue to rush down.

After a while, a lot of black gas came from all directions, transforming endlessly, with knives and guns, and even black flames that burned the surrounding swamp to the ground, presenting a large space.

As soon as Han Feng's mind moved, countless black fire marks appeared around him, so that the strong firepower confrontation smoothly burned those black qi to nothing without any accidents.

He descended again, all the way down, and passed three interceptions from unknown enemies in succession, but after he penetrated three thousand feet again, there was another mysterious diaphragm below.

The more this happened, the more certain he became that there was something unimaginable underneath, maybe it was someone from the Demon Clan, or it could be a treasure of the Demon Clan.

He clenched the Broken Sky Sword, and without hesitation, another sword slashed, and under the infusion of three powers, a layer of snow-white light appeared on the Broken Sky Sword, which successfully split through the obstacles and broke another hole.

He cut into it like lightning, and with a twist of his body, the whole person rushed down hundreds of feet away.

In the next stick of incense, Han Feng encountered more and stronger interceptions, but he broke through them three times and divided them by two, and rushed down without stopping.

When he broke the barrier of the third invisible barrier, he came to a huge underground space, thousands of feet high, and I don't know how it was formed.

In the center of this space, there is a lamp, the lamp is as white as jade, but the wick is as black as black jade, emitting bursts of black light.

These black lights are like spirituality, and from time to time they evolve into various forms, from demons to strange birds and beasts.

Then these images shattered, and everything turned into thousands of wisps of true demonic qi, rising in a curling manner, and then disappearing out of thin air, as if passing through space and going to the outside world.

Han Feng was stunned, he didn't expect that there would be such a magical existence, it was simply a great treasure, and it could actually derive the true demonic qi on its own.

Of course, he also knew that it should still absorb the power of the origin of the Demon Mountain World, otherwise how could it transform an endless stream of true demonic qi.

He tried to move forward, but he only moved a distance of more than a thousand feet, and was blocked by an invisible diaphragm, and no matter how hard he tried, it was useless.

He didn't dare to exert more powerful power, because even here, he was still suppressed by this world, and he couldn't burst out of his full strength.

In his mind, this lamp was so strange, most of it was also suppressed by the Magic Mountain World, and it was even very likely that it was taken care of by the ancestral talisman back then, and it was also sealed.

But even so, this thing was still infinitely powerful, and in the end, it still blocked Han Feng, making it impossible for him to get close.

Han Feng secretly pondered in his heart, thinking about how to break through the defense of this lamp, but he thought about it and didn't come up with a good solution.

He held the Heaven Breaking Sword, and in the case of suppressing cultivation, slashing horizontally and vertically, it was to no avail.

The colorful light at the center of his eyebrows flashed, and the five-element sigil appeared, blasting indiscriminately at this invisible diaphragm, but it did not break it.

Han Feng didn't toss for the time being, but he didn't give up either, silently immersed himself in the sea of souls and communicated with the remnants.

For a while, the remnant of the talisman has not moved at all, and I don't know what it is up to.

He communicated for a long time, but the remnant charm still didn't react at all, which made him very helpless and had to give up temporarily.

He sat in front of this invisible diaphragm in the air, silently thinking about countermeasures, and under the condition of being limited by the prohibition of this heaven and earth, he could not use many methods.

Han Feng's eyebrows suddenly bloomed with colorful light, and he comprehended the mystery with his heart, and before he knew it, he saw the form of this invisible diaphragm, which was actually densely formed by pieces of runes.

This was already the limit of what he could do, and in this state of suppressing his own cultivation, he couldn't last long, and after only a dozen breaths, he couldn't see the introverted rune of the invisible diaphragm.

With a quick glance, it was impossible for him to see any clues, so he pondered for a while, continued to expand his soul power observation, and examined it carefully.

In just half an hour, he watched it twelve times, but he only saw some clues, and there was still a long way to go to break this diaphragm.

Instead of being impatient, he took this obstacle as a perfect opportunity to hone his rune skills, and continued to observe the mysteries with great patience.

......

Time flies, and half a month has passed in a blink of an eye.

Han Feng also sat in front of this invisible diaphragm in the air, and did not hesitate to use the origin power of the soul bead to check the runes on its surface, and after countless studies, he finally cracked it.
