Seeing Mo Lin come over, the Bull Demon King smiled faintly and said,""Old Master is just recuperating for a period of time. You can go and do your own thing.”
During this period of time, the Bull Demon King did not cultivate at all. He was completely relaxed.
Occasionally, he would watch the sunset and give Mo Lin some pointers on his cultivation. After relaxing, his days were extremely pleasant.
Ever since he came to the Wilderness, the Bull Demon King had always felt a sense of urgency after learning about his current situation. His low cultivation made him lack a sense of security.
He knew the cruelty of the Primordial World because he had always been on tenterhooks, urging himself to move forward.
Now, after breaking through to the Zenith Heaven Golden Immortal and becoming the personal disciple of Sect Master Tongtian, he was finally no longer so panicked.
For several months, Bull Demon King had been living like this.
During this relaxing process, the Bull Demon King also recovered. His essence, qi, and spirit had all recovered to their peak.
On this day, the system upgrade was completed.
That familiar voice rang out in the Bull Demon King's mind.
"System upgrade complete, access to the Platinum Treasure Chest unlocked.”
"In view of the host's breakthrough to the Zenith Heaven Golden Immortal realm, the inferior-grade Connate Numinous treasure, the Mixed Iron Rod, has been upgraded to the middle-grade Connate Numinous treasure.”
After these two voices, the system fell silent.
Bull Demon King was already used to the system's method. It seemed that he had to find out the specifics himself.
"Platinum treasure chest?" The Bull Demon King muttered to himself.
Since it was only unlocked after the system upgrade, then the level must be higher than the Golden Treasure Chest. The Golden Treasure Chest had already obtained a god-level cultivation technique like the Nine Revolutions Mysterious Art. The Bull Demon King was instantly filled with anticipation towards the Platinum Treasure Chest.
However, anticipation was just anticipation. Only after obtaining the Platinum Treasure Chest would he know what he could get from it.
Right now, he was more interested in the system's second sentence.
"The Intrinsic Numinous treasure, the Iron Stick, has been upgraded to a middle-grade Connate Numinous treasure.”
The Bull Demon King had never heard of such a situation before. It seemed that it was a function of the system.
In Untainted Land, there was no way to upgrade a Primordial Spiritual Treasure. Primordial Spiritual Treasures were born from heaven and earth. Since they were born, the quality of Spiritual Treasures had been determined. There was no such situation where they could be upgraded later.
The only thing that was similar was the Cauldron of Heaven and Earth used by Goddess Nüwa when she created humans.
Speaking of the Cauldron of Heaven and Earth, its origin was quite mysterious.
In the chaos, there were 3,000 gods and devils. At the same time, there were four treasures called: The Heaven-Opening Divine Axe, the Chaos Green Lotus, the Jade Creation Butterfly, and the Chaos Pearl.
Great God Pangu was one of the gods. When Pangu opened the sky, the other gods came to stop him. He held the Heaven-Opening Axe, stepped on the Chaos Green Lotus, and fought with the other gods with the Jade Butterfly of Fate above his head.
The other gods were naturally no match for God Pangu. However, he was alone and dominated the group of gods. Although the other gods were all killed, Pangu was also heavily injured.
The battle was so intense that the sky turned dark. The Chaos was shattered, and the blood of the Chaos Godfiends splattered in the Chaos. Huge corpses that were thousands of feet tall floated everywhere.
However, at this moment, the world had already been created. Seeing that the Chaos Qi was about to devour the newly created world, Pangu, who was seriously injured, looked at the broken Heaven-Opening Godly Axe in his hand and could no longer split the Chaos.
Pangu sighed and stepped into it alone. He used his body to support the entire world.
As the heaven and earth opened up, the Chaos power was in chaos. The broken Heaven-Opening Axe in Pangu's hand was divided into three parts. The blade of the axe turned into the Pangu Banner, the back of the axe turned into the Taiji Diagram, and the handle turned into the Chaos Bell.
The Pangu Banner and the Taiji Diagram were obtained by Dao Ancestor Hongjun. After preaching in the Purple Cloud Palace, they were given to the Primordial Heavenly Venerate and the Grand Supreme Laozi respectively.
The Bell of Chaos transformed into Donghuang Taiyi's accompanying spiritual treasure.
The Jade Butterfly of Fate above his head also shattered. The largest part was taken by Hongjun, the Ancestor of Dao, while the rest were scattered all over Untainted Land.
As a supreme treasure that contained 3,000 Great Dao mysteries, Hongjun had even become a Saint with the help of the Jade Butterfly of Fate.
As for the Chaos Green Lotus under his feet, it directly disintegrated.
The Chaos Green Lotus had twelve leaves and twenty-four petals. At the center of the lotus, there were five lotus seeds.
After the Chaos Green Lotus disintegrated, the five lotus seeds turned into five twelfth-grade lotus thrones.
The petals turned into twenty-four Sea Calming Pearls.
The two largest lotus leaves turned into the River Map and the Book of Luo. The five lotus leaves fused with the innate five elements and formed the innate flags of the five regions: Wuji Apricot Flag, Green Lotus Flag, Floating Flame Flag, Plain Cloud Boundary Flag, Xuanyuan Water Control Flag; Five small lotus leaves transformed into five great spirit lamps: Eight Scenery Palace Lamp, Golden Cloud Lamp, Green Wandering Palace Lamp, Lotus Lamp, and Vulture Palace Lamp.
The root of the Chaos Green Lotus absorbed the Innate Slaughter Qi and turned it into the God Slaying Spear, which was obtained by the Demon Race's Luohou.
The lotus seed of the Chaos Green Lotus absorbed the power of the Origin and transformed into the Cauldron of Heaven and Earth.
The Cauldron of Heaven and Earth was first obtained by Dao Ancestor Hongjun and later given to Goddess Nvywa.
After absorbing the original power of the Green Lotus of Chaos, the Cauldron of Heaven and Earth had the ability to return to its original state and improve the quality of Spiritual Treasures and weapons. However, the Cauldron of Heaven and Earth could only transform Postnatal Spiritual Treasures into Primordial Spiritual Treasures at most. It was impossible to improve the level of Primordial Spiritual Treasures.
Back when he obtained the mixed iron rod, due to his low cultivation, a low-grade Primordial spirit treasure was already quite good for the Bull Demon King. It was also a great boost to his combat strength.
However, after advancing to the Zenith Heaven Golden Immortal Realm, although a low-grade Connate spiritual treasure was not bad, the increase in combat strength was not so obvious.
During this period of time, the Bull Demon King was still thinking about this problem. How could he obtain a higher-quality Numinous Treasure, or rather, how could he be thick-skinned enough to ask his master to bestow him one?
In the end, he never expected that the mixed iron rod he had obtained from the system was not an ordinary Connate Numinous treasure. It could actually be upgraded.
This made Bull Demon King extremely happy. Back then in Green Touring Palace, Sect Master Tongtian had said that he would reward him with a Spiritual Treasure. However, he had only wanted to break through to Zenith Heaven Realm and had not chosen a Spiritual Treasure.
Now that the mixed metal rod had been upgraded to a middle-grade Numinous treasure, he no longer had this worry.
Moreover, after such a long time, he had become very familiar with using the iron rod. It felt like a good killing weapon.
The Bull Demon King took out his iron rod and looked at it, which had been upgraded to a middle-grade Primordial spirit treasure. A faint smile appeared on his face.
Then, he suddenly thought of something.
