In the blink of an eye, Wuji had been in the Sun Moon Star for nearly a hundred years.
In the past hundred years, Wuji had told Xi and Chang Xi some interesting stories about Untainted Land from time to time, which made the two girls yearn for the lively Untainted Land. Chang Xi, in particular, was eager to try it out.
If Xihe hadn't stopped her, she would have asked Wuji to take her to the Untainted Land.
Of course, in the past hundred years, not only were Xi and Chang Xi interested in the Untainted Land, but they also had the intention to explore Wuji.
The two of them could clearly sense that Wuji was only in the Primordial realm, but for some reason, they could feel a trace of pressure from Wuji.
One had to know that there was a huge difference between a Primordial Unity Golden Immortal and a Quasi-Sage. There was no comparison at all.
Although Xi and Chang Xi were only at the Early Stage of Sage-to-be, they were still Sage-to-be!
As a result, out of curiosity, the two women unexpectedly let Wuji stay in the Sun Moon Star as a guest.
This was exactly what Wuji wanted.
The Lunar Star contained an extremely magical moonlight spiritual energy, which had a miraculous effect on cultivation.
At this critical moment, Wuji was naturally unwilling to let go of this opportunity.
On this day, Wuji was sitting cross-legged in the courtyard that Xihe had specially prepared for him. He was holding the Wuji Sword that was emitting a faint light, and his brows were tightly knitted.
To be honest, if he wanted to advance to the Zenith Heaven Golden Immortal Realm, Wuji would probably be able to do it immediately.
However, if he wanted to successfully upgrade the grade of the Infinite Sword, it would take quite a bit of effort.
All of a sudden, a light flashed in Wuji's mind. His eyes lit up, and with a thought, a bead that was emitting a chaotic light appeared in the air.
"System, if I fuse the Chaos Pearl into the Limitless Sword, will it be able to increase the grade of the Limitless Sword?
Was the Chaos Pearl suitable, or was the Jade Creation Butterfly fragment more effective?”
"Ding! Whether it was the Chaos Pearl or the Jade Creation Butterfly, as long as there was enough Great Dao Origin, they could be fused into the Wuji Sword and even reach the level of a Connate cardinal treasure.”
"That should require a lot of Great Dao Origin, right?!!”
"Ding! The Chaos Pearl and the fragment of the Jade Creation Butterfly each had 100 million Great Dao Origins, which could promote the Limitless Sword to the Connate Cardinal treasure level.”
When Wuji heard this, he could not help but choke. He did not even have 10 million Great Dao Origins on him now, let alone 100 million.
"Then should I only fuse with a small part of it? As long as the main body of the Limitless Sword could advance to a supreme-grade Connate Numinous treasure, it would be fine. There was no need for it to become a Connate cardinal treasure for the time being. There would be plenty of opportunities in the future!”
The most important thing for Wuji now was to complete the system side quest.
"Ding! It depends on how much Great Dao Origin is consumed. The host can explore it on his own!”
Hearing the system's reply, Wuji could not help but relax. As long as it was feasible, everything would be easy.
Thinking of this, Wuji's eyes focused. With a thought, he instantly controlled the Chaos Bead and began to slowly fuse it into the Wuji Sword.
However, things were not that simple.
Even though the Chaos Pearl was damaged, it was still a Connate cardinal treasure. How could the Limitless Sword, a mere superior-grade Connate spiritual treasure, withstand it?
If there were no other supplementary means, it would not take long for the Infinite Sword to explode completely from the Chaos Bead.
Fortunately, Wuji was prepared. He gritted his teeth and instantly took out one million Great Dao Origins, smashing them into the Wuji Sword.
A light "buzz" sounded.
The entire Wuji Sword emitted a dazzling glow, and the light of the Chaos Pearl began to blend with each other.
" It's starting to fuse together. It's indeed effective. Continue…"
Seeing that one million Great Dao Origins had been exhausted, Wuji took out another two million Great Dao Origins and continued to smash them in.
Time passed quickly.
A thousand years passed in the blink of an eye.
On this day, a huge explosion suddenly erupted from Wuji's location.
A powerful aura quickly spread in all directions.
"Hahaha, I finally succeeded!"
Wuji's hearty laughter spread.
After a thousand years, he had consumed millions of Great Dao Origins and finally integrated the Chaos Pearl into the Limitless Sword. Thirty percent of the Origins had fused into one, allowing the Limitless Sword to successfully advance to the level of a supreme-grade Primordial Spiritual Treasure.
The Chaos Pearl seemed to have become an inconspicuous "sword pellet" at the hilt of the Wuji Sword. However, Wuji did not dare to underestimate it in the slightest.
Whether the Limitless Sword could become a Connate cardinal treasure in the future depended on it.
"My main body, the Infinite Sword, has successfully advanced. Now, my potential has taken a qualitative leap and I have the potential to become an upper-level innate god.
"The only thing I lack now is some foundation.
However, as time passes, I will definitely be able to catch up and surpass them.”
Wuji carefully felt the changes in his body and was extremely excited.
"Before I advance to the Zenith Heaven Golden Immortal Stage, I still have to continue to strengthen my foundation and foundation to the maximum.
In this way, once he advanced to the Zenith Heaven, he would be far from what ordinary Zenith Heaven Golden Immortals could compare to!”
The Ultimate Sword returned to his body. With a thought, a ball of liquid that emitted a shocking blood-red light suddenly appeared.
Pangu blood essence!
Back then, Wuji had obtained ten drops of Pangu's blood essence as a reward after completing the system's side mission.
At that time, Wuji did not refine it immediately because his own potential and foundation were enough for him to consume.
But now, he had reached a limit. In order to strengthen his foundation and maximize his potential, Wuji finally decided to refine the ten drops of Pangu Blood Essence.
Pangu was the leader of the 3,000 Chaos Demon Gods, the son of the Great Dao, and the controller of the Great Dao of Force.
Even the entire Primordial World was created by him, and only after his body transformed into all things did it have boundless vitality.
The Primordial Spirit transformed into the Three Pure Ones. Even Emperor Jun and Taiyi, who were as powerful as Emperor Jun, were only two innate creatures, the Three-legged Golden Crow, born from the sun star transformed from Pangu's left eye.
Even the hair on Pangu's body would eventually turn into some extremely precious spiritual roots and spiritual treasures.
One could imagine how valuable ten drops of Pangu's blood essence were.
