Yin Yang Dongtian and others left, but Gu Tiange stayed.
Just when he was about to leave, the God's Eyes of Destiny, which was deducing at a high speed, discovered that there was something abnormal in the space here, and it was suspected that a big secret was hidden.
"Buzz buzz..."
Gu Tiange sat cross-legged on the ground, running the Great Destiny Technique at a very fast speed, releasing powerful soul power to cover the surroundings, sensing changes in the surrounding space.
About a day or so later, Gu Tiange suddenly opened his closed eyes and locked onto a certain space.
"Break it for me!"
The Sixteenth Soul Palace broke out of his soul sea and attacked the space where his soul was locked, tearing a gap in the space.
The next moment, his body flashed slightly, passed through the gap in space, and came to a space filled with terror and majesty.
"That's... the Nine Heavens Boundary Monument!"
In this mysterious space, Gu Tiange discovered a stone tablet nearly a hundred feet high, carved with mysterious ancient patterns, and filled with the power of the world.
After repeated deductions with the Divine Eye of Destiny, Gu Tiange discovered that the stone monument in front of him was most likely the legendary Nine Heavens Boundary Monument.
"It seems that the secret realm of the ancient Fire City was reproduced through the Nine Heavens Boundary Monument!"
Gu Tiange murmured to himself, enduring the overwhelming space pressure and arriving at the foot of the Jiutian Boundary Monument that was nearly a hundred feet high.
"I wonder if this third secret realm will collapse if I take away the Nine Heavens Boundary Monument!"
Gu Tiange is well aware of the value of the Nine Heavens Boundary Monument. If it can be moved to the Hongmeng Middle World, it will greatly improve the stability of the Hongmeng Middle World and accelerate the evolution of the Middle World.
"No matter, let's try it first!" Gu Tiange took a deep breath and said, "Maybe there is more than one Nine Heavens Boundary Monument in this secret realm."
As he spoke, Gu Tiange released powerful soul power to cover the surrounding area, and found that there was no abnormality around him. He ran the Hongmeng Heavenly Dao at an extremely fast speed, continuously shooting out streams of Hongmeng Immortal Power and Hongmeng Qi, breaking into the Nine Heavens Boundary Monument.
"Buzz buzz..."
Soon, the Nine Heavens Boundary Monument began to vibrate, filled with the terrifying power of the Nine Heavens, trying to refine the Hongmeng Immortal Power and Hongmeng Qi.
However, the levels of Hongmeng Immortal Power and Hongmeng Qi are far superior to the power of Nine Heavens, and the Nine Heavens Boundary Monument cannot refine them at all.
"Puff!"
A moment later, Gu Tiange was injured by the power of the Nine Heavens erupting from the Nine Heavens Boundary Monument, and a large amount of blood sprayed from his mouth.
"Devouring the body's defense!"
Gu Tiange took a deep breath, quickly evaporated his remaining blood on the ground, evolved a powerful devouring phenomenon, and continued to inject the Hongmeng Qi and Hongmeng Immortal Power into the Nine Heavens Boundary Monument.
As more and more Hongmeng Immortal Power and Hongmeng Qi broke into the Nine Heavens Boundary Monument, the resistance of the Nine Heavens Boundary Monument became stronger and stronger, constantly aggravating Gu Tiange's injuries.
"seal!"
Gu Tiange, who was seriously injured, struggled for about four days. He controlled the Hongmeng Immortal Power and Hongmeng Qi and finally sealed the Nine Heavens Boundary Monument.
"It's done!"
After successfully sealing the Nine Heavens Boundary Monument, Gu Tiange summoned the world in Hongmeng without hesitation, releasing a powerful devouring force and absorbing the Nine Heavens Boundary Monument with all his strength.
But the nearly 100-foot Jiutian Boundary Monument is too heavy, and the world in Hongmeng cannot absorb it at all.
"Could it be that we can only take it away by refining it?"
After trying several times to no avail, Gu Tiange's brows knitted together tightly.
"Forget it, let's try refining it first. If it doesn't work, then think of a way!"
After pondering for a while, Gu Tiange decided to stay here and refine the Nine Heavens Boundary Monument with all his strength until he could leave the border in the last month.
After making the decision, Gu Tiange ran Hongmeng Heavenly Dao at an extremely fast speed and began to refine the Nine Heavens Boundary Monument bit by bit.
Soon, a month passed.
Gu Tiange's ranking dropped from more than 8,000 to more than 40,000...
"Huh, this Nine Heavens Boundary Monument is really powerful, but in another month, I should be able to refine it!"
Gu Tiange took a deep breath, calculated the time, and continued to eliminate all distracting thoughts and refine the Nine Heavens Boundary Monument.
"Buzz buzz..."
As two months approached, the Nine Heavens Boundary Monument emitted a huge resonance and was basically refined by the Hongmeng Heavenly Dao.
"The world in Hongmeng, take it in!"
With a thought, Gu Tiange once again summoned the Hongmeng Middle World, and took the nearly 100-foot-high Nine Heavens Boundary Monument into the middle world.
Suddenly, the world in Hongmeng changed a lot. Not only did the world become more consolidated, but the rules of the world became closer to the fairy world.
However, a huge earthquake occurred in the third secret realm, and the blue sky burst with countless cracks, as if it wanted to collapse, frightening many disciples in the third secret realm.
"Walk!"
After successfully taking away the world in Hongmeng, Gu Tiange did not dare to wait for long, and directly tore the space apart, flying out of the mysterious space at an extremely fast speed, and quickly disappeared.
"What happened to the third secret realm?"
The incident in the third secret realm also alarmed the palace of the city lord of the ancient city of fire. Several immortal emperors of the Yan Clan immediately found the city lord who was wearing a fiery red robe and was in the five-star immortal emperor realm and asked about the situation.
"Why did the Nine Heavens Boundary Monument in the third secret realm disappear?"
The ancient city lord of Fire City knitted his brows tightly together and said solemnly.
"What, how is this possible..."
The Immortal Emperors of the Yan Clan said in disbelief.
They are well aware of the power of the Nine Heavens Boundary Monument, and even they cannot take the Nine Heavens Boundary Monument away.
"City Lord, do you know who did it?"
Yan Nanfei, who had just been promoted to the Grand Elder of the Yan Clan, asked in a low voice.
"I don't know..." The city lord shook his head and said, "That man reacted very quickly. He took away the Nine Heavens Boundary Monument and left immediately, so that I could not catch his figure."
"Give me the information about the disciples in the third secret realm quickly, I want to check it out!"
Yan Nanfei sensed the seriousness of the situation and shouted an order.
Soon, information about all the disciples in the third secret realm appeared in his hands.
Since Yan Buzhi was not conspicuous among these disciples, Yan Nanfei could not suspect him at all.
"Great Elder, are there any suspicious people on this list?" the Lord of Fire City asked in a low voice.
"No!" Yan Nanfei shook his head and said, "No matter how I look at it, I can't believe it. Some of them took away the Nine Heavens Boundary Monument."
"Could it be that the Nine Heavens Boundary Monument was not taken away by someone, but that something else happened?" The Immortal Emperor of the Yan Clan speculated.
"This is also possible!" Yan Nanfei was silent for a few breaths and said: "Everyone, let's quickly go to the space where the Nine Heavens Boundary Monument is sealed to see what happened there."
"Let's go!"
The Lord of Fire City directly opened the domain gate, led Yan Nanfei and others into the third secret realm, and arrived at the Nine Heavens Boundary Monument space at an extremely fast speed.
But Gu Tiange did not leave any clues. They searched hard for a long time but failed to obtain any valuable clues.
The disappearance of the Nine Heavens Boundary Monument has also become a mystery in their hearts.
In desperation, they could only inform Emperor Yan of this situation.
Soon, another three days passed.
The first round of the preliminary round has finally arrived in the last month.
