I became an immortal by synthesizing plants.

The two people inside the hall began to set up the formation.

Chen Qingshan went to ask the patriarch for the materials to refine the Zhou Tian Xing Chen Banner.

Of course, Chen Qingshan didn't ask for any random materials for refining top-tier spiritual treasures; he only asked for the most important spiritual materials.

They are the Starry Sky Divine Stone and the Guiding Spirit Stone.

As for the others, the branches and leaves of the Enlightened Fusang are used as secondary materials, while the Yellow Heaven Giant Cypress in the inner world provides chaotic energy.

The preparation time was not long this time, because Chen Qinghuai himself gathered a lot of stellar spiritual energy and collected a lot of stellar spiritual energy.

Chen Qingshan suddenly thought of using his own Sun God Fire as the core, drawing the power of the sun into the Zhou Tian Star Flag, and then using the sun as the core.

Chen Qingshan then went to tell Chen Qinghuai about it.

"It's a good idea, but I don't have control over the power of the sun. Will my natal magic weapon go out of control?" Chen Qinghuai asked hesitantly.

After all, the Sun is the star lord, existing in the same position as Ziwei.

Chen Qingshan shook his head and said, "You've already mastered the power of many stars, so what's so difficult about mastering the power of the sun?"

Chen Qinghuai was speechless at Chen Qingshan's words. "You yourself have the power of two star lords."

The problem is that he has only mastered some auxiliary stars and one main star, so controlling them will still be quite difficult.

However, Chen Qinghuai also knew that the Star Lord, as the core of the array flag, was definitely the best.

Chen Qinghuai gritted his teeth and said, "Fine, then, let's go with the sun!"

Chen Qingshan smiled and nodded, then suddenly said, "How about integrating it with Ziwei Star? With the two star lords taking turns, the power of the array flags will be even greater."

Chen Qinghuai refused outright; this was no longer a matter of whether he tried or not.

If he cannot control the two star lords well, then his natal spirit treasure will completely go out of control.

Chen Qingshan regretfully began preparing the materials.

Three months later, after Chen Qingshan had purified the materials, he began to refine the Zhou Tian Xing Chen Flag.

There are 36 poles in total, and each pole needs to draw on the power of the sun. Of course, it is much easier than when Chen Qingshan was refining the Sea-Illuminating Pearl.

Fearing that the laws of heaven and earth would once again cause trouble, Chen Qingshan remained constantly vigilant about the changes in the surrounding laws.

After completing the crafting of the 12th Zhou Tian Xing Chen Flag, Chen Qingshan relaxed his vigilance slightly.

Chen Qinghuai, who was providing inspiration from the side, was having a little trouble because he had to control the stars in the inner landscape to draw upon the stellar inspiration.

Seeing his state, Chen Qingshan had no choice but to speed up the refining of the Zhou Tian Xing Chen Flag.

Two hours later, the 24th Zhou Tian Xing Chen flag was completed, and Chen Qinghuai was already struggling to provide inspiration.

Chen Qingshan could only speed up the process and refine the remaining 12 Zhou Tian Xing Chen flags.

The 12 flags represent the Small Heavenly Circuit, and the 36 flags represent the Great Heavenly Circuit. This was made by Chen Qingshan using the same method he used when he refined the Sea-Illuminating Pearl.

At the moment of the completion of the Great Circulation, 36 flags fluttered in the wind, and Chen Qingshan instantly infused them with the divine power of his Sun God Fire, drawing upon the power of the sun and stars.

Chen Qingshan: "Qinghuai, come quick!"

Chen Qinghuai seized the opportunity and flew into the flowing Great Heavenly Cycle, imprinting his divine soul on each of the Heavenly Star Banners and infusing them with his own essence and blood.

The moment it was completed, the Zhou Tian Star Flag drew upon the power of countless stars, and began to rapidly increase its rank.

Its rate of improvement is no less than that of the Sea God Pearl, and it is also absorbing spiritual energy.

Chen Qinghuai reacted even faster, quickly drawing the star projections from the inner world to cover it.

The Zhou Tian Star Flags automatically floated to a star and emitted dark purple spiritual energy, which converged into a sun.

When the grade was raised to the level of a postnatal spiritual treasure, Chen Qingshan felt the surrounding laws of heaven and earth fluctuate again.

Just as Chen Qingshan was about to escape, he noticed that the laws of heaven and earth that had once blocked the upgrade of the Sea-Illuminating Divine Pearl had reappeared.

It also blocked the first stream of the laws of heaven and earth in advance.

Unfortunately, the materials Chen Qingshan used this time were not very good, and the Zhou Tian Xing Chen Flag was only upgraded to a mid-grade acquired spiritual treasure.

However, Chen Qinghuai had never seen a post-natal spiritual treasure before, and could only marvel at Chen Qingshan's amazing weapon-refining skills.

"Qinghuai, first store the Zhou Tian Star Flag in your dantian, and don't let others see it unless necessary."

Chen Qingshan warned.

Chen Qinghuai carefully examined the Zhou Tian Star Banner before cautiously storing it in his dantian to nurture it.

Seeing that nothing was wrong, Chen Qingshan told Chen Qinghuai to quickly comprehend his own laws.

Chen Qinghuai: "Thank you, Qingshan."

Afterwards, Chen Qinghuai vanished into the void and left.

Chen Qingshan adjusted his state and went to the Enlightenment Pavilion to comprehend the laws of the sun.

There are three years left before I head to Xianhe Road, or rather, a little over two years, since I will be going there in the spring of my third year.

In the blink of an eye, a year has passed.

However, the natural spiritual seed of the Qiyuan Ancestor still lacks the spiritual essence of heaven and earth to advance to the Golden Core realm.

However, the spiritual seeds that Chen Qingshan differentiates each year are all arranged to be fully utilized.

After all, the greatest loss would be to waste such an extremely rare spiritual seed.

However, it's relatively easy to find the upgrade materials for the Crystal Vein Purple Star.

Chen Qingshan, who was sitting cross-legged in the palace, waved his hand, and the six natural spirit tree seeds, seven crystal vein crape myrtle seeds, five fire dragon tree seeds, and eight nine spirit sword light grass seeds floated in mid-air.

A few days ago, the Mountain and River Ancestor said that he would come to collect the spirit seed today, so Chen Qingshan prepared it for them.

Moreover, the Nine Spirit Sword Light Grass, which had just been able to differentiate into spirit seeds, actually separated into eight seeds directly.

This immediately resulted in a production volume greater than that of other spirit species that had been separated for several years.

The Mountain and River Ancestor arrived at the palace shortly afterward, took the spirit seed, and asked:

"Qingshan, have you integrated any new spiritual plants in the past two years?"

Chen Qingshan shook his head and said, "Not yet, I haven't thought of any good combinations yet."

The Old Ancestor of Mountains and Rivers provided Chen Qingshan with several solutions.

But Chen Qingshan didn't think it was very good.

Finally, Chen Qingshan thought of the laurel and the Enlightenment tea tree that had failed to merge back then.

[Can be synthesized]: Enlightenment Tea Tree, Laurel.

[Synthesis Cost]: 40% of Qi Luck

Chen Qingshan was surprised to find that the synthesis process had been significantly less intensive, and an idea immediately came to him.

Chen Qingshan then asked the ancestor to bring more spiritual plant seeds.

Chen Qingshan planned to select the one with the highest synthesis cost and that was the most reasonable.

An hour later, Chen Qingshan discarded a large number of spiritual plants.

The alternatives are Laurel and Wudao tea trees.

Chen Qingshan looked down on the rest.

Suddenly, a jasmine plant meant for ornamental purposes appeared in Chen Qingshan's hand.

As for the other one, it is the Chaenomeles speciosa.

[Can be synthesized]: Rain-Calling Jasmine, Cloud-Clearing Camellia

[Synthesis Cost]: 60% of Qi Luck

Chen Qingshan took them as his first choice and then continued to combine these spiritual plants.
