Hearing the words of the red-robed man, Gu Xu nodded and walked straight towards the formation.

Although he had a deep attainment in the path of the rune array, when his gaze fell on the intricate diagrams on the surface of the boulder, he couldn't help but feel a slight feeling of dizziness in his mind for a moment.

He had to admit that the knowledge of the Rune Dao Formation Realm was like a vast and deep sea, and he was still far from touching its boundary.

For example, the "Tower of Babel" in front of him, which can help practitioners cross the two realms, involves a lot of advanced knowledge and skills that he has not yet mastered.

If he had time, he would have sat here for several hours, figuring out the principles of the diagrams—he believed that if he could fully comprehend every detail of the diagrams, his sigil skills would be taken to the next level.

It was only at this moment that a gray-white mist appeared in his field of vision again.

He will soon leave this era under the influence of the "Mixed Element Qi".

"It's strange," he thought silently, "I've been in the first era for days. But after the second and third time travel, they only stayed for a short time of less than a day."

If he remembered correctly, according to the description of the astrolabe machine spirit, those predecessors who traveled through the "return to the ruins" had only traveled once and returned to the original era.

Shuttle like him three times in a row is obviously a special case.

But he didn't have time to dig into why.

He held the "Brilliant Pen" in his hand, and under the reinforcement of the "Bright Candle", he once again unleashed the "Glowing Flame".

The sky suddenly flashed with firelight, like a fluttering firefly.

Immediately afterward, these orange-red rays of light joined together, completely enveloping the entire formation, like a hungry beast, greedily gnawing at the marks on the boulder.

The temperature of the air rose sharply, and Gu Xu's figure became more and more turbulent.

Not far away, the red-robed man looked at the bright and dazzling flames, and then looked at Gu Xu's gradually transparent figure, as if he suddenly remembered something, and his expression was a little dazed for a while.

When the formation patterns on the surface of the boulder basically disappeared, Gu Xuche completely disappeared under the foot of Kunlun Mountain.

His vision was once again filled with gray-white "Mixed Yuan Qi".

…………

Gu Xu held the "astrolabe" in his hand, walking in the misty world, as if he was in a dream.

There was nothing around him, and he couldn't tell the way.

Suddenly, a quaint, slightly rusty bronze shard appeared in front of his eyes.

The shard, as if it had been subjected to a strong gravitational pull, was flying towards him at a rapid pace.

He reached forward and grabbed the shards effortlessly.

At this moment, the "astrolabe" in his other hand suddenly began to tremble violently, and the surface became as hot as fire, as if he couldn't wait to become one with the fragments.

Gu Xu frowned slightly.

He thought that it would take a lot of extra effort to find the "Green Dragon" fragment of the astrolabe in the "Return to the Ruins".

I didn't expect it to come to the door on its own.

As if sensing the confusion in his heart, a white-haired, handsome machine spirit reappeared on the surface of the astrolabe, and said to him with a smile, "Master, have you forgotten that the rules of time and space in the "Return to the Ruins" are different from those in the outside world? This is where the laws of the world come to a long way—each one like a thread of silk, tightly intertwined, twisted by interfering with each other.

"This fragment of the 'Green Dragon' actually found you by following cause and effect."

"Cause and Effect ......"

Gu Xu nodded, and slowly spliced the fragments of the "Green Dragon" and the astrolabe.

Suddenly, at their joints, an extremely dazzling bright light and blazing temperature were emitted, as if they were welded together by an invisible force.

After a few seconds, the light faded.

The fragments merged with the "astrolabe" as a whole, and there was not the slightest crack in the surface that could be seen, as if it had never cracked.

The size of the machine spirit

It also seems to have grown a little taller, and his expression has become more and more vivid.

At this time, Gu Xu felt that countless new information was pouring into his mind from the "astrolabe" like a flood that burst the embankment, further enriching and perfecting the knowledge he had previously mastered.

His three powers were also greatly strengthened at this moment-

While "Wisdom" gives him a keen mind and the ability to remember, it also strengthens his perception, allowing him to not only detect hostility from a distance, but also enhance his intuition in battle.

In addition to pausing time, "Time" has added a way to speed up the flow of time, which can quickly age enemies during battle.

The distance that Qiankun can construct a spatial passage has increased from the original "within a hundred miles" to five hundred miles, and at the same time, it also allows him to use the laws of space to construct a "trapped array" and trap the enemy in it.

Even if it is an enemy with a higher realm than him, if he doesn't know anything about the laws of space, he may be hit.

Gu Xu took a deep breath and tried to digest these new skills.

He clearly felt that he was becoming stronger at a speed that was visible to the naked eye—a feeling that gave him a joy that came from the bottom of his heart.

…………

After about a few hours, the gray-white "mixed element qi" around it finally dissipated.

Gu Xu found that he was still riding on the small boat turned into a talisman seal, sailing on the endless sea, tossing and undulating in the rolling waves.

Jumping in the "Guixu" waterfall, the encounter with Xi in the primitive era, the battle in the Yaowang Sect, and the "Babel Tower" large array destroyed at the foot of Kunlun Mountain...... It's like it never happened.

It's like a dream of Nanke.

He took the copper coin out of his coat pocket and used divination to verify that he had successfully returned to his old era.

The copper coin was face up, giving him an affirmative answer.

"Now, I have to find the last fragment of the 'White Tiger' of the 'Astrolabe'," he thought to himself silently, "Boss Luo once said that as long as the 'Astrolabe' is made whole, I will awaken the unimaginable power that belongs to the 'Emperor Ziwei'.

"This will become my capital to deal with Emperor Tianxing in the future."

As he thought, he closed his eyes and threw his consciousness into the "astrolabe", trying to sense the direction of the last fragment.

…………

At the same time, in the basement of the "Green Shadow" organization.

Luo Chuan, the head of the exorcism division, was sitting cross-legged on the futon, closing his eyes and practicing.

Suddenly, a strange sensation arose in his consciousness - as if a pair of invisible hands had opened his eyes and made him see a wider and more real world.

Luo Chuan knew that his Heavenly Deduction Technique had improved again.

A smile appeared on the corner of his mouth, and he muttered to himself, "It seems that the great cause of the emperor has taken another step forward."
