I, the Emperor of Heaven return

Nie Tian remained calm and continued walking forward. He would not attack rashly until he knew the opponent's strength.

However, he guessed that this person's strength could not be too strong, otherwise there would be no need to hide his strength and he could just kill people directly.

After all, this is Tianhuang City. If the Shura Sect sends a peak expert, it will definitely alarm other people, which is not good.

"Sir, what is that?" At this moment, Han Ling's voice suddenly sounded, with a hint of surprise.

"Huh?" Nie Tian's eyes narrowed slightly, and he was immediately attracted by a red boulder in front of him.

The boulder was ten meters in diameter, red as blood, and exuding a strange blood-colored light. There was a faint force surging in it, like water flow, with continuous threads surrounding the boulder in circles. You could actually see blood. The ripples spread out.

"What kind of stone is this?" Pu Feifan was also stunned and extremely happy. He actually took a step forward and wanted to touch the bloody boulder.

"Be careful!" Nie Tian shouted in shock when he saw this scene.

Han Ling was right next to Pu Feifan, and he immediately reacted and caught Pu Feifan.

"What, what's wrong?" Pu Feifan was so frightened that his face was as white as paper and his forehead was covered with beads of sweat.

"This blood stone is weird. It seems to be the eye of a certain space-time spiritual formation." Nie Tian said solemnly, motioning for everyone to retreat.

He felt a strong space-time aura from the blood stone. He screamed just now because he was worried that the blood stone would release powerful space-time pressure like the Gate of Nothingness and crush Pu Feifan directly.

Just now, Nie Tian's entire attention was focused on the person following him, so he didn't pay much attention to his surroundings.

Only then did he realize that he had walked into a spiritual formation unknowingly.

"Ren Yihang, pay attention to the man in green behind us. He doesn't have any breath on his body." Nie Tian sent a message to Ren Yihang to remind the latter to pay attention.

Ren Yihang reacted quickly, with a calm expression on his face. He glanced at the man, and his eyes couldn't help but flicker. The man in green didn't have any energy fluctuations on his body, just like an ordinary person.

This is so weird!

You know, even for a peak Heavenly Emperor, it is extremely difficult to completely hide the energy aura around him.

This person must know some weird method to control his aura to the extreme.

Ren Yihang secretly paid attention to this person, but he always remembered that his mission was to protect Nie Tian!

After Nie Tian told Ren Yihang, he spread out his spiritual consciousness. The holographic divine patterns were like invisible tentacles, carefully sensing the atmosphere of the surrounding space.

On the holographic projection, many runes are surging, very faint, but it gives people an extremely vast feeling.

These runes must have been very powerful originally, but after hundreds of thousands of years of erosion, they slowly became weaker.

"This is an ancient time and space spiritual formation, but it has existed for too long, and less than 1% of the power of the spiritual formation is left." Nie Tian said secretly in his heart, and then his eyes were focused on the bloody boulder in front of him.

He could sense that the blood-colored boulder in front of him was the center of the spiritual formation!

Nie Tian controlled the holographic divine pattern and carefully sensed the breath inside the blood-colored boulder. Slowly, his expression became complicated.

"Huh?" Nie Tian frowned. He actually felt another breath of time and space on the blood stone. It seemed that there was also a time and space spiritual formation inside the blood stone.

"Array within array!" The next moment, a name appeared in Nie Tian's mind, and he was extremely surprised.

He once heard that there are spiritual array masters who can set up spiritual arrays in spiritual arrays, and the power of built-in spiritual arrays is stronger than external spiritual arrays!

Nie Tian felt that the air of time and space inside the blood stone seemed to be stronger than the air of time and space in the outside space, which was very strange.

"Could this blood-colored boulder be a door to some time and space, like the door to nothingness, leading to another world?" Nie Tian speculated in his heart, his eyes flashing continuously.

There is most likely a time and space master hidden within the bloody boulder, and this boulder has withstood most of the time and space pressure, so even if you are close to the boulder, you will not feel too strong time and space pressure.

Nie Tian hesitated whether to enter the bloody boulder in front of him and test it out.

This move was very dangerous. If the bloody boulder released strong space-time pressure and Nie Tian tried to retreat, it would be too late.

"Master!" At this moment, the voice of Lord Shelob sounded, with a hint of excitement.

"She Luo, did you find anything?" Nie Tian asked in surprise.

"Master, do you feel that the aura of this blood stone is a bit special and seems familiar." Demon Lord Shelu said with a smile.

"Seems familiar?" Nie Tian was stunned for a moment, sensing it with his spiritual consciousness, and then his eyes trembled. He immediately thought of something and exclaimed in his heart: "The Alchemist Guild's Alchemy Soul Stone!"

After being reminded by Demon Lord Shelu, Nie Tian immediately remembered that there was an aura in the blood stone in front of him, which was similar to the aura of the Core Soul Stone he had encountered in the Three Thousand Little World.

Nie Tian once used the Danxin Soul Stone to improve his mental power, but later he never had the chance to understand the Danxin Soul Stone.

He still remembered that there were many strange runes on the Danxin Soul Stone. Now that he thought about it, they were some kind of divine runes.

The blood-colored boulder and the Danxin Soul Stone have similar auras. The two stones should be made of the same material, but they have different divine patterns carved on them.

"Master, in addition to having a breath close to that of the Core Soul Stone, this blood stone seems to have an aura as well." Lord Sheluo smiled again and said hehe.

"There is another breath?" Nie Tian was stunned for a moment, and then he sensed the blood-colored boulder again, and his expression gradually became extremely strange.

"It seems to be..." Nie Tian's voice trembled slightly, and he could not believe the breath he felt, and his expression was a little stiff.

"Yes!" The Demon Lord Shiluo knew what Nie Tian felt, and he smiled and said, "It is the breath of Sansheng Grass!"

Sansheng Grass!

Nie Tian felt the breath of Sansheng Grass on the blood-colored boulder, which was too weird.

It was obviously a piece of stone, how could there be the breath of Sansheng Grass?

Just now, Nie Tian's attention was all on the blood-colored runes on the blood stone, and he did not pay attention to the breath of the blood stone itself. After the reminder of the Demon Lord Shiluo, he noticed the weirdness of the blood stone.

The next moment, Nie Tian suddenly thought of something, his expression was stunned, and he froze completely.

Others saw the change in Nie Tian's expression, and they were all stunned, but they did not dare to disturb Nie Tian.

After more than ten seconds, Nie Tian finally reacted. Looking at the blood-colored boulder in front of him, his eyes flashed with an extremely hot look, like a hungry man seeing delicacies.

"Shiluo, you mean, this blood stone is..." Nie Tian calmed down a little, his forehead was full of sweat, and his voice was shaking uncontrollably.

"Yes." Shiluo Demon Lord nodded solemnly, his small body dancing almost excitedly, and said with a smile: "If I guess correctly, this blood stone is what old man Jian said, the Three-Life Stone!"

"Three-Life-Stone!" Hearing these three words, Nie Tian's pupils trembled violently, and the whole person stiffened again.
