Generally speaking, man-made spiritual treasures were acquired, while primordial spiritual treasures were nurtured by heaven and earth. However, this was not absolute. Acquired things could also reverse the primordial, and the most important one was the Cauldron of Heaven and Earth.
The Cauldron of Heaven and Earth was a pre-world supreme treasure. Its function was to return to its source and transform the post-world into the pre-world.
In fact, the power of a Postnatal Spiritual Treasure was not weaker than a Primordial Spiritual Treasure. This was because a Primordial Spiritual Treasure could suppress providence and possess the laws of heaven and earth. It could also be used to cut corpses, while a Postnatal Spiritual Treasure did not have this function.
Didn't you see that during the God Sealing War, the Heaven Flipping Seal was also a Postnatal cardinal treasure, but it needed to borrow the Connate Five-Element Flags to resist it?
In addition, the Heaven and Earth Black Yellow Exquisite Pagoda and the Heaven and Earth Primordial Sky-measuring Ruler were also Postnatal Merit Cardinal treasures, but their power was not inferior to Connate Cardinal treasures. They could even suppress providence.
Li Tian had the Cauldron of Heaven and Earth, so he could refine Primordial Spiritual Treasures as he pleased.
The Primordial Five-Element Flags were formed by the five lotus leaves of the Chaos Green Lotus. They were all top-grade Primordial Spiritual Treasures. If the Primordial Five-Element Flags were combined, they could naturally become a Primordial Supreme Treasure.
Although there was only one word difference between a Primordial Supreme Treasure and a Primordial Spiritual Treasure, hundreds of Primordial Spiritual Treasures could not compare to a Primordial Supreme Treasure. Although there were not many Primordial Spiritual Treasures in the Untainted World, there were only a handful of Primordial Supreme Treasures, which showed how rare they were.
Li Tian took out the Cauldron of Heaven and Earth and the Primordial Flags of the Five Regions. He threw them into the Cauldron of Heaven and Earth, then lit the Primal Spirit Fire and started refining.
The Primordial Flags of the Five Regions had the same root and origin, so it was not troublesome to combine them into one. However, what Li Tian wanted was not a pure defensive supreme treasure, but a supreme treasure that combined defense and attack.
With the Primordial Flags of the Five Regions as the main body, Li Tian took out countless heavenly and earthly treasures, such as the essence of stars, the essence of Geng Xin, the divine sun stone, the essence of Tai Yin, the essence of Wu Tu, and other spiritual materials to refine.
After the Spiritual Treasure was formed, Li Tian took out the Evil Qi, Vengeful Qi, Murderous Qi, and so on that he had collected during the Dragon-Phoenix Tribulation to enhance the power of the Spiritual Treasure.
After an unknown period of time, the supreme treasure in the Cauldron of Heaven and Earth gradually took shape. At this time, countless dark clouds began to gather in the sky above the Three-Immortal Island.
"What happened?"
"What happened?"
The living beings on Three Immortal Island looked at the dark clouds that were gathering in the sky and were terrified. The pressure brought by the dark clouds was so heavy that they could hardly breathe, as if a disaster was coming.
In the Holy Zhi Palace, Li Tian did not care about the upcoming Heavenly Tribulation. Whenever a Primordial Spiritual Treasure was artificially refined, the Heavenly Dao would send down a test. If one could pass it, they would naturally succeed. If they could not, they would be destroyed by the Heavenly Tribulation.
Li Tian sat cross-legged in mid-air and focused his mind. His hands moved continuously, forming a seal. Now that he was at the final juncture, he was not allowed to relax at all. Otherwise, all his previous efforts would be ruined.
"Out!"
Li Tiandao shouted and patted the Cauldron of Heaven and Earth. A large flag rose from the Cauldron of Heaven and Earth and flew out of the Dao Palace.
Li Tian followed closely behind and arrived in front of the main hall of the Holy Zhi Palace with the flag. At this time, the tribulation clouds in the sky had already finished brewing, and a destructive aura came head-on.
With the combination of the Primordial Flags of the Five Regions and Li Tian's refinement with the Cauldron of Heaven and Earth, the flag had already reached the level of a Primordial Supreme Treasure. It was no worse than the Taiji Diagram, the Pangu Banner, and the Bell of Chaos.
For such a Connate Cardinal treasure, the test of the Heavenly Dao was naturally the highest. It was the ninety-nine tribulation, which meant that it had to experience the refinement of the ninety-nine eighty-one bolts of heavenly lightning.
Even Li Tian couldn't interfere with this lightning tribulation. The Spiritual Treasure had to survive it on its own.
"Boom!"
A bolt of purple lightning struck down, striking directly at the flag in the air, as if it wanted to destroy it.
However, when the purple lightning struck the flag, it did not suffer any damage at all.
After all, the Primordial Flags of the Five Regions were the main body, and each of them was a top-grade defensive treasure. A mere heavenly lightning naturally could not destroy them.
"Boom! Boom! Boom!"
As the heavenly lightning struck down one after another, the flag remained motionless.
The color of the heavenly lightning gradually darkened, and its power gradually increased. The later it went, the stronger the heavenly lightning became. Even Li Tian did not dare to underestimate it.
"Boom!"
The 80th bolt of lightning struck down. The color of this bolt of lightning had completely turned black. Its power even shocked Li Tian. According to his observation, this bolt of lightning could completely kill a Quasi-Saint.
Even he would be severely injured if he did not have a spiritual treasure to protect him. It was comparable to a casual strike from a Merit Saint.
Unfortunately, the heavenly lightning was still unable to cause any damage to the flag. This made Li Tian very satisfied. It was not in vain for him to spend so much effort and precious materials to refine this treasure.
"Boom!"
Finally, the eighty-first bolt of lightning, which was also the last bolt of lightning, struck down. The color of this bolt of lightning was black and red, and its power frightened even Li Tian. If he was struck by this bolt of lightning, he would probably immediately turn into a pile of ashes, or perhaps not even leave behind ashes.
The power of this lightning bolt was comparable to the full power of the Three Separations Saint. Even a Great Perfection Pre-Saint would die without a defensive treasure.
Li Tian couldn't help but clench his fists. Although he was very confident that the flag wouldn't be destroyed by the heavenly lightning, he was still very nervous.
In the void, the black-red lightning struck the flag, but its terrifying destructive power did not destroy the flag. It could be seen that its defensive power was amazing, not inferior to the Xuanhuang Pagoda.
The eighty-one bolts of heavenly lightning had passed. Logically speaking, the tribulation should have ended. However, the tribulation clouds in the void still did not dissipate, as if they were hesitating.
However, before the tribulation cloud dispersed, the flag in the void seemed to be a little impatient. It directly soared into the sky and swept across, directly absorbing the huge tribulation cloud into the flag.
After breaking through the tribulation clouds, the flag continued to soar into the sky. It swept across the starry sky and absorbed an ancient star system.
It seemed to be used to announce its appearance.
"From now on, you will be called the Great Flag of the Primordial World!”
