Although Luo Zheng slowed down, his speed was actually extremely high. After three hours, he had already penetrated seventy or eighty thousand miles underground.
At this time, his aura had completely disappeared, just like a tiny pebble in the underground mud.
"Fu Canghui's method of concealing breath is indeed wonderful. Using this method of concealing breath, even a strong person in the middle stage of Heaven's Dao will have a hard time sensing me!"
At that time, Luo Zheng accidentally entered the world of Cang Ning, met Zhao Qian, the leader of the Fucang Society, and obtained the unique hidden breath method of the Fucang Society from him.
Luo Zheng didn't pay too much attention to it before, but as his cultivation level improved, he discovered the benefits of this hidden breath method.
As long as this hidden breath method is used, it will be difficult for even the best experts to detect it.
However, the only disadvantage is that when operating the Hidden Breathing Technique, the true energy cannot be violently activated, otherwise it will affect the Qi in the body and render the method ineffective.
"Look, this must be the gathering point of Guixian Tower. It's actually protected by a heaven-level formation!"
Luo Zheng entered the 90,000-mile underground and immediately discovered that wherever he looked, there was a huge formation in motion.
This formation emits terrifying flame energy, like a huge fireball, which is much more powerful than any earth-lung fire.
Judging from the power of this formation, it is at least the third level of heaven level.
"I didn't expect that the defense of Guixian Tower would be so tight, and a powerful formation would be deployed. This would be a bit troublesome."
Luo Zheng looked bad. He didn't expect that after sneaking here, he couldn't enter the gathering point of Guixian Tower.
Originally, he hoped to find some evidence from here to prove the connection between Guixian Tower and the Giant Spirit Clan, so that he would be more confident in convincing the Longzun Immortal Emperor.
But now it is impossible. Luo Zheng cannot forcefully break the formation, and it is almost impossible for such a powerful formation to have any flaws.
"Now that we're here, let's take a look before talking."
Luo Zheng thought for a while, then walked around the formation to observe.
Anyway, it doesn't take much time to walk around the formation, and no matter what happens in the future, this Guixian Tower will definitely be removed. Understanding the power of the formation first can also help you know yourself and your enemy.
"The flames of this formation seem to be some kind of yin fire. Once it touches the body, it is very difficult to put out and is extremely dangerous!"
When Luo Zheng got close to the formation, he felt not high temperature, but a cold and cold atmosphere. This kind of yin fire was more difficult to deal with than the yang fire and was extremely difficult to deal with.
Although the Thunder of Destruction has a huge power that can break through this formation, it will definitely be sensed by the masters in the formation.
"Hey, what is that?"
Suddenly, Luo Zheng sensed that there seemed to be a flaw at the bottom of this huge formation. Although it was only extremely subtle, it could not escape his sense.
As soon as he moved, he immediately sneaked towards the bottom of the formation.
"Well, what is this? A sapling!"
If there was any flaw in the formation, Luo Zheng saw from a distance a small green tree as thick as an arm growing out of the ground.
Except for the roots and a very small part of the trunk, the other parts of this small tree are wrapped in the formation, and the gap where the formation appears is where the formation contacts the trunk.
What surprised Luo Zheng even more was that this small tree looked ordinary, but it was unscathed by the formation's yin fire and looked completely full of life.
"This little sapling must be of great importance. It seems that the secret gathering place of Guixian Tower is established here, and I'm afraid it has a great relationship with this little sapling!"
Luo Zheng felt that he might have discovered a huge secret.
He browsed through the Tongtian Record in the Divine Sea, but found that there was no record about Xiaoshu in the weapon refining volume.
Originally, the Tongtian Record Refining Tool Volume recorded a large number of various magical weapons, Taoist weapons, and artifacts, and the heavenly materials and earthly treasures for refining the weapons were all-encompassing and included.
This small sapling has not been recorded in the Tongtian Lu, which proves that the value of this object may even exceed the artifact.
"Is it a sacred tree?"
Luo Zheng's heart skipped a beat, but it was a pity that Xuan was not there, otherwise Xuan might be able to prove it given his vast knowledge.
"By the way... Luo Riyue is the son of the God King. He must be well-informed in the divine plane. Maybe he can be recognized!"
Thinking of this, he called Luo Riyue out of the door of no return, "Luo Riyue, we are in danger now. You should be careful to restrain your breath. Don't be discovered by others, otherwise it will be very troublesome."
"This is underground, Master. This is a formation of the third level of the Heavenly Realm. It is difficult for a strong person in the late stage of the Tianxuan Realm to escape from it. Could it be that this place is the secret gathering place of the Guixian Tower?"
Luo Riyue immediately became lifeless, like a piece of dead wood. He looked around and saw a look of wonder.
"Yes, this is the gathering point of Guixian Tower, but now the focus is not on Guixian Tower, but on that small tree."
Luo Zheng stretched out his hand and said.
"That's...the World Tree!"
Luo Riyue looked in the direction pointed by Luo Zheng and immediately exclaimed.
