Before the closed-door cultivation, Chen Xiao also set up a cultivation plan for Luo Qingli and the others, and he refined a small quantity of basic elixirs to help them improve their cultivation.

They are just starting their cultivation journey, and progress shouldn’t be too fast, or it will affect their foundation.

If the foundation were not taken into account, with Chen Xiao’s abilities, he could easily use elixirs to boost their strength to the level of Energy Transformation Grandmaster within a month!

But doing so is meaningless.

Forcibly enhancing cultivation requires a substantial amount of elixirs for support, but if too many realms are broken through in a short period, it will lead to accumulation of many impurities within the body, negatively affecting future cultivation.

For over twenty years, Chen Xiao has never used elixirs to enhance cultivation.

Xuan Daozi always emphasized solid cultivation, with every bit of power gained through hard work, making his reaching Half-step Grandmaster at such a young age far more impressive than others.

This time, if not for urgent circumstances, he would not have chosen to use the Tianxuan Great Rejuvenation Pill to aid his breakthrough.

However, while enhancing cultivation with elixirs has drawbacks, as long as he has enough patience to expel the impurities when refining the elixir, there will be no major impact.

Just doing this... 𝒇𝓻𝓮𝓮𝙬𝙚𝒃𝒏𝓸𝙫𝒆𝙡.𝓬𝓸𝒎

Some Heaven and Earth spiritual power within the elixir will also be expelled as impurities. Thus, many are reluctant to discard these impurities.

This results in an unstable foundation for them.

Therefore, Chen Xiao specially advised them that when absorbing the elixir’s potency, they must expel all the impurities within the elixir completely.

Once Chen Xiao’s mind calmed down completely, he also brought out all the materials needed to refine the Tianxuan Great Rejuvenation Pill.

Then, a flame appeared in his palm.

The Xuan Yang True Qi within his body, extremely yang and firm, is the best choice for alchemy.

The elixirs refined using Xuan Yang True Qi have purer potency and are of much higher quality than ordinary elixirs, offering a natural advantage.

Afterward, he successively placed those materials into the alchemy furnace.

The process of alchemy demands extreme caution, with precise timing for refining materials, fire intensity, and various meticulous controls!

Any minor detail can determine success or failure.

Two days later.

A rich aroma wafted from the alchemy furnace.

An elixir flew out from the alchemy furnace.

Instantly, the rich aroma permeated the entire room.

Chen Xiao grabbed the Tianxuan Great Rejuvenation Pill in his hand, his eyes full of ecstatic joy.

The surface of this Tianxuan Great Rejuvenation Pill glowed faintly with a light green hue, with natural elixir patterns entwining around it.

It’s top-grade quality!

This far exceeded his expectations.

"With this Tianxuan Great Rejuvenation Pill, my chances of breaking through to the Grandmaster Realm should be ninety percent!"

Adjusting himself to the best state, Chen Xiao swallowed the elixir.

A vast potency immediately spread through his entire body...

At once, he activated the Tianyang Jue, refining this potency bit by bit, allowing it to flow into his dantian.

The greatest distinction between a Grandmaster and a Half-step Grandmaster is the qualitative change in the inner strength within the body, transforming from inner strength to pure spiritual power.

But the Tianyang Jue that Chen Xiao cultivates is somewhat unique.

The Xuan Yang True Qi is inherently extremely yang and firm, far surpassing the inner strength cultivated by ordinary people.

Additionally, even before breaking through to Grandmaster, a portion of spiritual power automatically emerged within his body, and as his realm elevated, the spiritual power transformed became increasingly abundant.

However, this spiritual power was an exceedingly dominant force, which his previous physique could not withstand, hence he rarely utilized it.

Nevertheless, with his cultivation of the Mysterious Yang Body, this hidden concern vanished.

Now, he only needs to transform all the inner strength within his body into spiritual power to successfully break through to the Grandmaster level.

This refining process lasted several days.

After fully refining the Tianxuan Great Rejuvenation Pill, Chen Xiao felt as though his entire body was brimming with abundant power, as if his meridians were about to burst! He then began purging the impurities from the elixir’s potency, and once all impurities were expelled, he transformed this potency into inner strength, then compressed, compressed again, and compressed further before channeling it into his dantian, ultimately transforming it into purer spiritual energy...

Ten days later!

"Bang——"

Chen Xiao felt a barrier within his body had broken open!

A powerful aura spread across his body!

Slowly opening his eyes, an immense aura surged outward!

"So... this is being a Grandmaster?"

"This power, it’s remarkable!"

He could clearly feel the monumental change within himself compared to before!

The Xuan Yang True Qi within his body had transformed into Xuan Yang Spiritual Power, becoming even more domineering and fierce, with assaulting power sharply soaring, and the strength within vastly multiplied compared to before!

No wonder people say the chasm between Half-step Grandmaster and Grandmaster is insurmountable!

The difference is too immense!!!

Chen Xiao took a deep breath, "Now that I’ve broken through to the Grandmaster realm, given the special nature of Xuan Yang Spiritual Power, coupled with my solid foundation, and alongside my strong physical strength, while I may not claim invincibility among Grandmasters, I certainly would face few opponents!"

But he lacked much knowledge about this realm.

If the Grandmaster level is also divided into early, mid, late, and pinnacle stages, then his current strength is at least nearly invincible in the early Grandmaster stage.

He could even rival the mid-stage Grandmaster!

Chen Xiao confidently mused that should he encounter Zheng Yiqi again...

Crushing him would be a cinch.

Unfortunately... Zheng Yiqi was already crippled by Mo Pinfan, leaving no chance for practice.

He glanced at his phone, realizing that he had spent a full ten days on this round of seclusion!

However, it’s not unusual for an average person to take three to five months, or even three to five years, perhaps even ten years or more, to break through from Half-step Grandmaster to Grandmaster!

Many are stuck at the Half-step Grandmaster threshold for life!

"Now that ten days have passed, I wonder what’s happening outside." Chen Xiao took a deep breath, then opened the door and stepped out of the closed cultivation room.

"Chen Xiao, have you finally completed your seclusion?" Qin Lan emerged from the kitchen, carrying a dish.

"Has Big Brother Chen finished his seclusion?" Li Biyun also joyfully ran out, apron-clad.

During the absence of Chen Xiao, the place lacked some vitality.

Chen Xiao smiled and nodded, "During these past ten days, did anything special happen?"

Qin Lan replied with a smile, "Nothing particularly special happened, though everyone began diligently cultivating, temporarily setting aside career pursuits under your influence."

"However, things outside are not peaceful..."

She explained, "Now, the Dragon Vein is nearly fully awakened, and the Heaven and Earth spiritual power has become much richer than before, causing those Kunlun martial artists to flood into the secular world."

"Especially those martial artists from the Eight Hidden Sects..."

"They’ve now formed an extremely powerful force in the secular realm."
