Two days later, Lu Feng, Xu Man, Liu Ling'er, Dao Maniac, Wu Maniac, Han Yue, Ye Chenfeng and others returned to the stronghold established by Tianxuanzong on the edge of the Wasteland.

If there were no Lu Feng, Xu Man, and Liu Ling'er, it would be difficult for the other people to break out of the wasteland safely and arrive at the stronghold of Tianxuanzong.

Through the formation of that giant city, back to Tianxuanzong, several people parted ways, and Lu Feng returned to Yangmen.

The faces of Han Yue and the others have always been ugly, envious of Lu Feng's transformation, and their eyes are red at Lu Feng's creation.

After a long drive, Lu Feng went straight to the deepest part of the Yang Gate and headed towards the Burning Valley.

The Burning Valley is the core area of the Yang Gate, and the people who can enter the Burning Valley are all strong people in the Qi Domain Realm, and they are qualified to be the elders of the Yang Gate.

Lu Feng has reached the peak of the Gang Qi Realm, he has the strength to leapfrog the challenge, he can fight with the real Qi Domain powerhouse, his body has been washed by the spiritual liquid of heaven and earth, and he is extremely tough, it should not be a problem to enter the Burning Valley.

Soon after, flying over the Earth Flame Array, passing the ranking stone tablet, a thousand-zhang high fire ridge appeared in front of Lu Feng's eyes, and a monstrous fire was burning on it, extremely hot, starting from this fire ridge, the aura was more than ten times more violent, burning mountains and boiling the sea, and the space was boiling.

There is a special formation here, you can't fly, you can only climb the fire ridge step by step, and endure the burning of the fire, this is undoubtedly an extremely painful test, but for Lu Feng, it is a kind of training.

Soon, Lu Feng stood on the top of the Fire Ridge, and he came to a vast valley, where the earth was fissioning, and there was magma flowing everywhere, and the temperature was terrifying.

This is a valley surrounded by volcanoes, it can be said that it is the most dangerous place in the region where the Yang Gate is located, the violent fire attribute aura is even more terrifying than the Earth Flame Array, if you can break into here, the speed of cultivation is even faster than the Earth Flame Array.

The entire valley is a huge formation, specially designed for the strong people of the Qi Realm, after reaching the Qi Realm Realm, each small realm is a hundred times more difficult than the Gang Qi Realm, and it requires a more majestic heaven and earth aura.

Lu Feng jumped down from the mountain, only to notice that in many places here, small formations were paved with high-grade spirit stones, forming a large formation, releasing a majestic aura like the sea, and only then did it form a burning valley of Yangmen.

This is too surprising, to maintain such a huge formation, covering such a vast valley, the number of high-grade spirit stones to be consumed every day can only be described by two words: terrifying, over the years, the consumption of spirit stones is an unimaginable number.

In the hundreds of states covered by Tianxuanzong's strength, all the spirit mines are under the control of Tianxuanzong, and in the regions outside these large states, some of the great spirit mines are also occupied by Tianxuanzong, and there are strong people guarding them, and in the wasteland, there are also many spirit mines mined by Tianxuanzong.

Only a big sect like Tianxuan Sect, with a strong foundation, could establish such a huge formation and cultivate a strong Qi Realm within the sect. The more powerful the martial artists in the sect, the more cultivation resources they can compete for for the sect.

If it weren't for the great sects in the human realm, it would be too difficult for the powerhouses of the Qi Domain Realm to cultivate to the peak of the Qi Domain Realm, and it would be almost impossible to even reach the Great Percent of the Qi Domain Realm, and there would simply not be enough Heaven and Earth Spiritual Qi for them to cultivate.

Lu Feng also noticed that those spirit stones that had been depleted of spiritual energy were piled up on top of the Fire Ridge, and under the burning of the surging fire, those abandoned spirit stones gradually merged with the Fire Ridge.

He thought of a very terrible thing, the heavy fire ridge that surrounded the entire valley, could it be that it was made up of abandoned spirit stones, if that was the case, the foundation of the Xuanzong that day was really jaw-dropping.

In the center of this vast valley, there is a splendid temple, resplendent in gold, as if immortal, the land wind jumped down the mountain and swept towards the palace.

At the speed of stepping on the snow and stepping on the clouds, in a moment, Lu Feng came to the front of this palace, more than a dozen halls are magnificent and ancient, each one is ten zhang high, the years have not left too many traces on the temple, ** heavy, exuding a suffocating coercion, ordinary warriors do not dare to approach at all.

There is a square where you can play with the square circle, paved with special jade, not afraid of high temperatures, you must know that ordinary stones will gradually melt away here.

The square exuded a gentle glow, and Lu Feng saw many martial artists sitting in the center of the square, and one of them, a red-haired old man, sat in the air, teaching the others the cultivation method.

After reaching the Qi Domain, the True Qi forms a special field outside the body, and the martial artist is almost the only master in his own field, and the formation of the field, with the formation, will increase the power exponentially.

It can even be said that every Qi Domain powerhouse is a formation master. The formation can only exert the true power of the formation in the hands of the powerhouse of the Qi Domain Realm.

There were more than 100 people sitting on the ground listening to the lecture, all of them were over thirty years old, and there were even old people over sixty years old, they listened attentively, and they didn't even notice that Lu Feng stepped on this square.

The red-haired old man's status in the Yang Gate was obviously extremely high, and he must be the top powerhouse of the Yang Gate to be qualified to teach other martial artists the cultivation method, and everyone looked at the red-haired old man with a trace of respect and awe.

Lu Feng walked straight over, and heard the voice of the red-haired old man, what the old man taught, in Lu Feng's opinion, was of no value, when he was in the cultivation world, he traveled through three thousand states, as long as he survived the catastrophe, it was possible to leave the cultivation world and ascend to the broader upper realm, his understanding of the formation was far beyond any qi realm powerhouse in the human realm.

Soon, Lu Feng approached everyone, and they listened attentively, not noticing Lu Feng's arrival.

The red-haired old man closed his eyes and taught the cultivation method, but he was the first to notice that someone else was here, but he didn't open his eyes.

"I'm almost done talking, and you're only here now, so it's a little late. The red-haired old man said lightly.

Everyone was slightly shocked, and even some people's faces were flushed with anger, those who came to listen to the old man in red teach the cultivation method knew the time in advance, and at the end of the day, someone came, which was simply a great disrespect to the old man in red.

Everyone turned around, and they saw a young face that was beyond everyone's imagination, and their expressions were stunned.

With such a young face, it didn't look like a powerhouse of the Qi Realm at all.

"Is it a young disciple who has just stepped into the Qi Domain Realm and broken into the Burning Valley?"

Someone asked, this is what other people think, but they can't think of a second possibility.

Even if he has just stepped into the Qi Realm, his face is a little too young.

"No, he hasn't reached the Qi Realm yet, and he is a disciple at the peak of the Gang Qi Realm!"

A master found a trace of abnormality, judging from the true qi fluctuations faintly emanating from Lu Feng's body, this son definitely did not reach the Qi Domain Realm.

As soon as these words came out, a look of disbelief swelled in the eyes of everyone in the square.
