Chapter 189 Simulation Again: Northern Sea Dragon Kun, the True Dragon Clan!
As everyone departed, the mountaintop suddenly felt much emptier. Lu Yu looked around, his brow furrowing slightly, and suddenly realized that a familiar figure was missing.

“Senior Hei Qing,” Lu Yu turned to the burly man standing beside him like an iron tower, “Zi Yan… she hasn’t come out of seclusion yet? It’s been a month, she should have completed her breakthrough by now.”

Hei Qing stood with his arms crossed, a helpless smile on his rugged face: "Zi Yan's breakthrough process is going smoothly, but the concentration of her bloodline is extremely rare. The energy required for her to advance to the Dou Zun level is too enormous, and the whole process is much longer than expected."

He looked towards the back mountain and continued, "After all, this is a breakthrough across an important realm, and it can't be rushed. That girl asked me to tell you not to worry, she knows what she's doing."

Upon hearing this, Lu Yu nodded thoughtfully: "I see. Breaking through to the Dou Zun level requires a massive amount of energy. It took me two whole months to complete my breakthrough. Zi Yan has exceptional talent, so the time and energy she needs far exceed that of ordinary people, which is understandable."

His tone became more relaxed: "In that case, let's wait patiently. With Ziyan's talent and foundation, it's only a matter of time before she succeeds in breaking through."

Little Fairy Doctor also said gently, "In that case, we shouldn't disturb her too much. It's the right thing to do to let Ziyan focus on her breakthrough."

Hei Qing nodded with satisfaction: "That makes sense. With the help of that so-called spirit-gathering array, that girl will be out of seclusion this month, so there's no need to rush."

Lu Yu looked towards the back mountain, his eyes filled with anticipation: "Then let us wait for good news. When Zi Yan emerges from seclusion, our Tianmu Mountain Range will gain another Dou Zun powerhouse."

The three looked at each other and smiled, then headed towards Tianshan Terrace on the mountainside.

—————————————————————

Soon after,

A quiet meditation room.

Lu Yu sat cross-legged on a futon, his expression serene. Before him, a pale blue light screen slowly unfolded.

"let's start!"

[Ding! Extracting a simulated identity for the host—]

[Selection successful. Please choose one of the following three roles.]

[One, Dragon Demon Palace Spy—Due to your outstanding appearance, you were recruited and trained by the Dragon Demon Palace as a spy, and ordered to infiltrate the Northern Cang Spiritual Academy to lie low.]

[Second, Northern Sea Dragon Cub—You are a Northern Sea Dragon Cub wandering the Hundred Spirits Continent. You possess the natural qualities of a divine beast, and upon adulthood, you may even have the potential to glimpse the Earthly Sovereign Realm. However, you are currently just a little creature at the Divine Soul Realm.]

[Three, a student of the Northern Cang Academy—You are an ordinary student of the Northern Cang Spiritual Academy, but you possess a little-known "special talent."]

Please make your choice——

Lu Yu's gaze shifted between the three options before finally settling on the second one.

"The three options are all pretty much the same, but I've simulated the second option once."

"With the experience from last time, this time should go much more smoothly. This is the one!"

[Selection successful! Identity loading...]

[Simulation begins——]

[In your first year, while wandering in the Eastern Spirit Realm of the Hundred Spirits Continent, you accidentally consumed a thousand-year-old Transformation Herb. Under its influence, you prematurely transformed into a human, but due to insufficient cultivation, you became a blue-haired boy resembling a twelve-year-old.]

In this life, instead of rushing to achieve quick success and infiltrating human cities, you began cultivating the Earthly Supreme-level cultivation technique you had previously obtained from Qing Yanjing—the Heavenly Serpent Transformation Dragon Scripture.

[In the second year, relying on your powerful bloodline and the extraordinary Heavenly Serpent Transformation Scripture, you naturally broke through to the Fusion Realm and began your solo journey through the Eastern Spirit Realm of the Hundred Spirits Continent.]

Not long after, you stumble upon a newly revealed spiritual treasure trove, where a top-grade spiritual fruit, the "Netherworld Fruit," has ripened and emerged, attracting several late-stage Fusion Realm experts to vie for it.

The Netherworld Fruit is a rare, top-grade spiritual fruit. It nourishes the soul and strengthens its essence. It also has a powerful restorative effect on those with damaged souls, making it one of the rare spiritual fruits for healing soul trauma.

[Everyone was blinded by rage, their spiritual techniques and artifacts clashing wildly. You remained expressionless, and amidst the chaos, you suddenly struck. The Emperor's Seal Technique, three seals stacked upon each other, erupted with a deafening roar, blasting the five Heavenly Fusion Realm experts who attempted to surround you, along with their protective artifacts, into dust. Amidst horrified gazes, you seized the Netherworld Fruit.]

[You fully understand the principle that possessing a treasure invites trouble, and after obtaining the Netherworld Fruit, you left the Spirit Treasury without hesitation.]

However, after you left the Spirit Treasury, you were surrounded by a group of experts lying in ambush outside. Their eyes were filled with greed, and their target was the Netherworld Fruit in your hand.

[You showed no fear and launched the first attack. The Heaven-Burning Spirit-Igniting Secret Technique was activated in three stages simultaneously, your aura surging. The Emperor's Seal Technique was unleashed with overwhelming force, instantly killing several people and establishing your dominance on the spot; immediately afterward, the Five-Round Fire Array was deployed, with five fire spirits surrounding and protecting you, intimidating enemies from all directions.]

[Taking advantage of this brief respite, you consumed the Netherworld Fruit and rapidly refined it, causing your soul power to surge. Seeing that the situation was hopeless, the others had no choice but to retreat.]

[In the third year, your cultivation broke through to the Transformation Realm. Leveraging your status as a Level 5 Alchemist, you openly established the "Spirit Treasure Merchant Guild," rapidly accumulating wealth and connections by selling high-quality pills.]

[Secretly, you established the Soul Palace, hiring assassins and cleverly instigating conflict among various forces in the Eastern Spirit Realm. Although they are stronger than those in the Northern Spirit Realm, their strongest members are only at the Heavenly Realm. Under your covert manipulation, the entire Eastern Spirit Realm descends into chaos, while your merchant guild continues to grow stronger amidst the turmoil.] [Using the guild's vast intelligence network and resources, you quickly gathered information about Mu Chen of the Northern Spirit Realm. With memories of your past life, you know this young man has extraordinary potential, and that he is also connected to the ancient Floating Pagoda Clan.]

[Therefore, you decided to secretly expand the Soul Palace's influence to the Northern Spirit Realm, and quietly fund the growth of the Pastoral Domain's power within the Northern Spirit Realm.]

[In the fourth year, you successfully broke through to the Heavenly Realm. Using the Heavenly Demon Puppet crafting method from your past life, you collected all the corpses of powerful individuals who perished in the chaotic battles and secretly crafted them into an army of Heavenly Demon Puppets that obeyed only your commands.]

[In just a few months, you have crafted dozens of Heavenly Demon Puppets with strength ranging from the Fusion Realm to the Transformation Realm, including three powerful puppets forged from the corpses of Transcendent Realm experts.]

[Subsequently, relying on this fearless and absolutely loyal puppet army, you swept through the Eastern Spirit Realm with overwhelming force, suppressing all resistance forces, truly unifying the Eastern Spirit Realm, and becoming its master.]

After consolidating your rule, you learn through the Merchant Guild's intelligence network that news has arrived from the Northern Spirit Realm that the Shepherd Domain and the Willow Domain are engaged in fierce warfare.

[Knowing this was an excellent opportunity to further invest in Mu Chen, you dispatched an elite team under the name of the "Spirit Treasure Merchant Guild," carrying a large amount of spirit coins and pills to the Northern Spirit Realm to help Mu Chen turn the tide of the war. This timely assistance left a deep impression on Mu Chen, who remembered this "investment."]

In this way, Mu Yu would owe favors to both the Spirit Treasure Merchant Guild and the Soul Palace.

[In the fifth year, this time you did not choose to link your bloodline with Mu Chen. Instead, you used the resources of the Spirit Treasure Merchant Guild and spent a considerable amount of money in the Eastern Spirit Realm to request a spirit array master to set up a teleportation array for you to the Northern Cang Continent.]

[Through this formation, you will rapidly expand the Lingbao Merchant Guild's influence across the Northern Cang Continent. Thanks to the profound alchemy techniques inherited from the Endless Fire Domain, the pills you sell are remarkably effective, quickly establishing a foothold and gaining widespread fame throughout the Northern Cang Continent.]

However, the rapid development of the Chamber of Commerce inevitably angered the Shadow Chamber of Commerce, one of the three major chambers of commerce and a long-established power in the Northern Cang Continent. The Shadow Chamber of Commerce began to use various means to suppress and exclude the Spirit Treasure Chamber of Commerce in all aspects.

Faced with the overwhelming pressure from the powerful figure behind the Shadow Merchant Guild, you assessed the situation and chose to temporarily avoid confrontation, outwardly feigning weakness. Secretly, you went alone to the Northern Cang Spiritual Academy, found Mu Chen, and bluntly demanded that he repay the favor you had done for him in the Northern Spiritual Realm years ago.

[Mu Chen kept his promise and finally obtained a drop of the incomparably precious Northern Sea Dragon Kun essence blood for you.]

[In the sixth year, at the peak of the Divine Soul Realm, you consumed the essence blood of the Northern Sea Dragon Kun. With this drop of divine beast essence blood containing immense energy, you secluded yourself for arduous cultivation, breaking through the shackles in one fell swoop and stepping into the Supreme Realm!]

[After emerging from seclusion, you stormed the Shadow Merchant Guild headquarters with overwhelming force, personally slaying the guild leader, a being with supreme cultivation. This battle shook the entire Northern Cang Continent!]

From then on, the Lingbao Chamber of Commerce absorbed most of the Shadow Chamber of Commerce's businesses, greatly enhancing its prestige and undeniably replacing it as one of the three major new chambers of commerce on the Northern Cang Continent.

In the seventh year, Mu Chen returned from the Spirit Academy Tournament, successfully breaking through to the Supreme Realm, and prepared to travel to the Tianluo Continent for training. You entrusted the Spirit Treasure Merchant Guild to a capable subordinate and decided to travel with Mu Chen to that more expansive continent.

[The two of you traveled together, traversing the continent. While passing through the Shang Continent, you happened to encounter Princess Lin Jing of the Martial Realm being besieged by members of the Xuan Tian Palace; the situation was critical. Without hesitation, you and Mu Chen immediately intervened.]

However, a powerful elder from the Xuan Tian Palace suddenly appeared, his overwhelming aura attempting to kill you. At the critical moment, a cold and aloof figure silently emerged. The Martial Realm Mistress, Ling Qingzhu, merely raised her jade-like hand, instantly suppressing the arrogant elder, and the world returned to peace.

[Once the storm has passed, Ling Qingzhu extends an invitation to you in gratitude for your help. Mu Chen, on the other hand, must continue his training in the Great Luo Heaven Domain.]

And so, you parted ways with Mu Chen. He went to the Great Luo Heaven Domain, while you went to the Martial Realm with Ling Qingzhu.

[In the eighth year, you arrived in the Martial Realm with Ling Qingzhu. This vast land, created by the Martial Ancestor, possessed boundless spiritual energy, orderly structure, and countless powerful figures, leaving you deeply impressed.]

[Just then, the True Dragon Clan sent an envoy to the Martial Realm to discuss important matters. The Martial Realm held a grand banquet in celebration. During the banquet, your close relationship with Lin Jing and your charming words and actions won the favor of the young princess, attracting the attention of the True Dragon Clan members present.]

After the banquet, a Celestial Elder of the True Dragon Clan summoned you privately. He didn't say much, but simply flicked his finger, and a stream of light containing the violent power of a dragon's thunder entered your mind.

"Young man, this technique is called 'Thunder Emperor Dragon King Fist,' a supreme offensive divine technique imbued with the power of thunder. Judging from your unique physique, you may be able to withstand its fierce and domineering nature. I hope you will use this technique wisely and not succumb to its power." Having said this, his figure vanished silently.

In the ninth year, in order to comprehend the "Thunder Emperor Dragon King Fist," a supreme offensive divine technique, you ventured alone to the infamous and perilous Ten Thousand Thunder Abyss within the Martial Realm.

[Deep within the Thunder Abyss, you found a place where the power of thunder was most pure and violent. Enduring the pain of being devoured by countless thunderbolts, you observed the birth and death trajectories of heaven and earth's thunder day and night, verifying the Nine Heavens Thunder-Drawing Technique with the key techniques of the "Thunder Emperor Dragon Fist."]

[In the tenth year, after a full year of arduous cultivation, the bloodline originating from the Northern Sea Dragon Kun within you has been fully activated, further sublimating amidst endless thunder. Taking advantage of this opportunity, you have broken through the bottleneck and entered the Fifth Rank Supreme Realm!]

[At the same time, you were surrounded by lightning, and your punch was accompanied by the roar of a dragon and the howl of thunder, successfully cultivating the "Thunder Emperor Dragon King Fist" to the minor completion level!]

[This simulation ends——]

You can choose one of the following three items.

【1. Netherworld Fruit (Heavenly Level)】

Second, the Celestial Demon Puppet (Transcendent Level)

【Three, Thunder Emperor Dragon King Fist (Great Perfection Divine Technique)】
