After Di Jun and Tai Yi returned to the Demon Court's great hall together, Di Jun looked at Tai Yi, pondered for a moment, and then spoke:
"Tai Yi, our Demon Court's top-tier combat power is insufficient compared to the Wu clan. While our bottom-tier combat power surpasses theirs, it cannot control the overall situation. I want to create a grand formation to integrate the Demon Court, so Brother wants to enter seclusion for a period. Bai Ze and Kun Peng are busy teaching the demons to learn the demon script, and I don't entirely trust Kun Peng. This period, the Demon Court will be entrusted to you!"
Tai Yi looked at Di Jun, knowing that Di Jun was aware of his dislike for managing the Demon Court. Now, Di Jun was making this request, which meant there was no other choice. Tai Yi nodded and said:
"Big Brother, rest assured!"
Seeing Tai Yi agree with a nod, Di Jun's face broke into a smile. He nodded and said:
"Don't worry, it won't take long. I already have some ideas! You'll have to endure this for a while. Brother knows you don't like these things, but for your and my Great Dao, you'll have to bear with it for a bit!"
Tai Yi heard this and replied:
"It's not a hardship. Many people desire this position of Demon Emperor but can't attain it. Big Brother, don't think this way!"
Di Jun nodded and then returned to his secluded chamber to begin his retreat.
Upon returning to his secluded chamber, Di Jun took out the River Diagram and Luo Book. Di Jun accidentally discovered the trajectories of celestial bodies within the River Diagram and Luo Book.
Di Jun attempted to comprehend it, but it proved incredibly profound, with hints of formation operation within.
After discovering the planetary movements in the River Diagram and Luo Book, Di Jun wished to see the difference between the star movements within this spiritual treasure and those in the Primordial World.
Under Di Jun's careful observation, he found that the star movements within the River Diagram and Luo Book were indeed consistent with the star movements in the Primordial World.
Di Jun knew this was his fortune. He was proficient in the Way of Formations. If he could create a formation that could harness the power of the stars in the sky, its offensive capability would be terrifyingly immense.
Di Jun believed his mastery of formations was no weaker than Tongtian's. From his previous discussion on the Sun Star with Tongtian, Di Jun had already coveted Tongtian's Immortal Slaying Formation.
That formation not only could be used against enemies but also, if arranged in advance with sufficient time, would unleash terrifying destructive power.
So much time had passed, and with Tongtian's capabilities, that Immortal Slaying Formation must have become even more formidable!
The moment Di Jun thought of discovering the trajectories of the Zhou Tian stars, he gained confidence that he could evolve this grand formation, and it would surely not be inferior to Tongtian's Immortal Slaying Formation!
Di Jun meticulously studied the method of star movement. Gradually, a rough blueprint formed. It was unrealistic to command all the stars in the Zhou Tian by himself. Di Jun pondered for a moment and decided to choose the Tai Yin and Tai Yang stars as the formation eyes, the three hundred sixty-five main stars as the roots, forming the Great Zhou Tian.
Then, choose fourteen thousand eight hundred minor stars as branches, forming the Minor Zhou Tian.
Finally, incorporate the myriad demons of the Demon Court as the leaves and branches.
After resolving the method of star movement, Di Jun pondered how to draw down the power of the stars from the heavens to be used for his own benefit.
Di Jun contemplated for a long time but still could not find a solution. Thus, he emerged from seclusion to seek out Tai Yi.
Seeing Di Jun emerge, Tai Yi happily said:
"Big Brother, you've been in seclusion for a thousand years. Have you solved the formation you spoke of?"
Di Jun sighed and replied:
"Little Brother, Brother still has a problem to solve! I've pondered tirelessly but still cannot find a solution!"
Tai Yi responded with an "Oh" and asked:
"Big Brother, what problem can you not solve? Why don't you tell me?"
Di Jun replied:
"Your brother is pondering how to draw down the power of the stars from the heavens!"
Upon hearing this, Tai Yi pondered for a moment and then said:
"Big Brother, perhaps I have a way!"
Di Jun's eyes lit up, and he asked:
"What way!"
Tai Yi lowered his head for a moment and then said:
"When I was in Kunlun, Master told me that by forging flagpoles with Star Steel and weaving banners with Star Threads, one could form Star Banners capable of mobilizing star power!"
Di Jun's eyes gleamed with joy, and he asked:
"Can you forge these Star Banners!"
Tai Yi nodded and replied:
"Yes, Master taught me during my time in Kunlun!"
Di Jun was overjoyed and exclaimed:
"Tai Yi, then help Brother forge three hundred sixty-five Great Star Banners, one hundred eight thousand four hundred Minor Star Banners, and additionally, two Star Banners for the Sun Star and the Tai Yin Star!"
Tai Yi's mouth gaped in astonishment, and he exclaimed:
"Big Brother, why are you forging so many Star Banners? This will be the death of me!"
Di Jun knew it was indeed a lot and said somewhat sheepishly:
"Tai Yi, just help Brother out!"
Tai Yi pressed his hand to his forehead, sighing wearily, and said:
"Big Brother, you're bullying your brother!"
"Alright, you want Star Banners for those stars. For these Star Banners to be able to draw down star power, they must be made with Star Steel exclusive to that star, and the same applies to the Star Threads!"
Upon hearing this, Di Jun informed Tai Yi of all the stars he needed. Tai Yi noted them down one by one and then prepared to go out in search of materials.
Seeing Tai Yi about to leave, Di Jun called out:
"Tai Yi, wait!"
Tai Yi stopped and looked at Di Jun. Di Jun walked to Tai Yi's side and said:
"Thank you! Tai Yi, come, Brother give you a hug!"
Seeing this, Tai Yi replied:
"It's nothing, Big Brother. We are brothers!"
After Di Jun and Tai Yi shared a hug, Tai Yi left the Demon Court and headed straight for the Sun Star.
As the Sun Star was Di Jun and Tai Yi's homeland, Tai Yi naturally made it his first stop.
Upon arriving at the Sun Star, Tai Yi quickly found the Sun Star Steel. Tai Yi had even played with this Sun Star Steel when he was on the Sun Star, but he hadn't recognized it then.
With the Sun Star Steel in hand, Tai Yi immediately went in search of the Sun Silkworms, as the Star Threads exclusive to the Sun Star were spun by these Sun Silkworms.
After finding the Sun Silkworms, Tai Yi collected enough silk to weave approximately three banners and then departed for the Tai Yin Star.
Although the Tai Yin Star faced the Sun Star, Tai Yi had not spent much time there and was not familiar with it. Tai Yi spent a considerable amount of time searching for the exclusive Star Steel and Star Threads of the Tai Yin Star.
However, during his time in Kunlun, Yuan Shi had taught Tai Yi the origins of these exclusive Star Steel and Star Threads, and Tai Yi had remembered them all.
During Tai Yi's time in Kunlun, Yuan Shi had not only taught him the art of forging but also imparted to him the characteristics and origins of all the forging materials in the world.
When encountering materials that Tai Yi couldn't understand, Yuan Shi even personally took him out to find them and explain them to him one by one.
It was precisely because of Yuan Shi's meticulous teaching that Tai Yi was able to remember them. Otherwise, even if Tai Yi found them now, he might not recognize them.
After finding what he needed on the Tai Yin Star, Tai Yi left the Tai Yin Star and proceeded to the next constellation.
