Mengfei turned her gaze away from the Tianyi's clone and focused on converting her immortal qi. Immortals used immortal qi, mortal cultivators used true qi, and spiritual qi was ever-present in all realms, but the origin of all qi is essence.

Thanks to understanding herself after being struck by Emperor Soulfish's attack while contending for the Sovereign Nine Yin Lotus, Mengfei had come to understand herself better and loosened the shackles on her cultivation.

The Immortal Realm, otherwise known as the Daoseeking Realm, was split into the four minor realms: Pathfinding Dao Immortal Realm, Seamless Dao Immortal Realm, Extremity Dao Immortal Realm, and the final Origin Dao Immortal Realm. In modern times, the word dao has been removed from the names.

In the Pathfinding Immortal Realm, once the cultivator completely forms their Daoseed, they will enter the Seamless Immortal Realm. For a seamless immortal monarch to advance to the Extreme Immortal Realm, they must master a portion of the five elemental laws to produce immortal qi of five elements and nurture the Daoseed with them, causing it to sprout into a Daotree.

Once the Daotree grows to the limit and three blossoms form, they will enter the Origin Immortal Realm. The three blossoms represent three independent laws used to advance and evolve the immortal's primary Dao, hence the name Origin Dao Immortal Realm. From there, only by achieving apotheosis could the cultivator advance.

Mengfei had grown her Daotree to the limit, and three flower buds had formed. The buds represented that she had passed the greatest hurdle in entering the Origin Immortal Realm. All she needed now was time to nurture and bloom the buds.

Simultaneously, the immortal qi generated by Mengfei Daotree ceased to exist, and a mixture of immortal essence and qi, known as essence qi, started to fill her body. Essence qi was the trademark of an immortal sovereign, so she could be considered a half immortal sovereign.

Mengfei frowned when she detected a pillar of light directly descending onto Jade Peak. She recognized it as the unique travel method of the three immortal palaces situated in the Vast Void. But even if she did, it was still akin to someone entering her house without her permission.

"Greetings, Grand Elder Xi."

Mengfei recognized the immortal elder as someone who should have left with Grand Elder Zhang to the Broken Primordial World. She had an ominous premonition.

"What is it?" She asked directly.

The immortal elder took a breath to calm down and said, "Disciple Xi's jade pendant broke while inside the Broken Primordial World."

Instantly, he felt as if heaven and earth had changed. Even Jade Peak Palace disappeared, and in its place was a hellish realm beyond mortal comprehension. The immortal elder staggered and fell onto his knees. "Please calm your anger! Disciple Xi's jade pendant broken may just mean something happened, and he might still be alive. Grand Elder Zhang wants me to—"

When the immortal elder's perception of the world had returned to normal, he realized that Grand Elder Xi had disappeared. He looked around with muddled eyes.

"What happened?" Moments later, several immortal elders rushed towards Jade Peak. "Why did Grand Elder Xi tear through the spatial boundaries and directly enter the Vast Void?"

After the first immortal elder explained, the other immortal elders could help but cast condemning gazes upon him. "You, ah! Right now, it is a critical period between the sect and the Anti-Heaven Alliance, and the Tripartite Alliance. After Grand Elder Xi's action, do you think the other forces won't take action?"

"I, I, I'm just fulfilling my orders." The immortal elder said, his face paling at the consequences of his actions.

Zhang Cuiying, the second grand elder and known as Empress Voidink to the wider world, frowned as she sensed a presence storming towards Ink Poem Palace through the Vast Void.

"Why are you here?" Grand Elder Zhang asked with a frown.

"Why else. Tell me, what happened to my son?" Mengfei asked and walked directly in front of Grand Elder Zhang.

Grand Elder Zhang inwardly cursed. This was why she had told the immortal elder she sent as a messenger to go to the sect master to report Tianyi's problem. He must have disobeyed her orders, thinking that he could gain some small benefits.

She sighed. Since Mengfei had already arrived, there was no point in hiding the information any longer, so she informed Mengfei of everything she knew.

"I'm going," Mengfei said after hearing.

Grand Elder Zhang reached out to grab her hand but discovered that Mengfei easily broke free. "You can't. The last time you entered, you lost an arm."

Mengfei continued without care.

"Are you really going to risk everything? What you are doing right now is reckless. You should calm down and form a more comprehensive plan than just entering alone." Grand Elder Zhang said. "We still have some elders present, have them enter and search for Disciple Xi. Once they discover a trace of him, then you can enter if they can't do anything."

Only then did Mengfei stop her tracks. She paused and glanced at the elders present, causing their scalps to tingle. Mengfei was as expressionless as always, but they couldn't help but feel as if a snake was staring at them, and they were the frogs.

Grand Elder Zhang sighed in relief. She quickly arranged for a search team to depart. At the same time, she couldn't help but question what could possibly cause Tianyi's pendant to break. The pendants were made of extremely hard material and would not easily break even in the Broken Primordial World.

She thought that Tianyi would be the least likely to die among the disciples present, but she was not an omniscient god. She glanced at Mengfei. If Tianyi died, she needed to prepare her fellow grand elder.

"Grand Elder Xi, you really shouldn't have left the Huang Realm at this juncture."

Mengfei stayed silent and continued to burn a hole into the Broken Primordial World with her eyes.

"The Numinous Sword Sect had already unified the Numinous Realm and even renamed it to display their hegemony. Our Buzhou Immortal Sect is also descended from one of the Pure Ones, and we aren't worse than them. Your master had always wanted to see the Huang Realm unified under the Buzhou Immortal Sect. It was only a pity that she fell to the Dragon Emperor."

Mengfei's body trembled but didn't speak. After a few minutes, she opened her mouth again. "Ten years. I'll wait ten years. If they haven't found Tianyi yet, I'll enter myself."

Grand Elder Zhang sighed. 'This is the best I could do.'

But before the ten-year period could come to an end, an unexpected guest arrived at the five-year mark.

"Emperor Yanxu, why are you here?" Grand Elder Zhang asked upon seeing Numious Sword Sect's grand elder appear. She glanced to the side at Mengfei, who was still staring at Broken Primordial World. She returned her gaze to the intruders. "And you even brought ten immortal monarchs."

"How could I not come after detecting the famed prodigy of the Buzhou Immortal Sect arriving?" Emperor Yanxu said with a smile that did not reach his eyes.

"Hmpf, it seems that you did not expect me here." Grand Elder Zhang said.

"Empress Voidink's presence was indeed a miscalculation. But, is it really fine for you to be here with all the disturbance in the Huang Realm?"

"You don't need to worry about such matters. You should go back to managing your Numinous Realm." Grand Elder Zhang snapped back.

"Tsk, tsk. I want to, but it's just been too peaceful, unlike the Huang Realm. I'm a little envious. The Numinous Realm hasn't seen a genius like the Dragon Emperor in some time." Emperor Yanxu said with a chuckle.

Grand Elder Zhang's face turned dark and delivered a frosty glare at the immortals from the Numinous Sword Sect.

Before Grand Elder Zhang could retort, Mengfei turned around and asked a question. "Why are you here?"

"I'm simply curious as to your presence here." Emperor Yanxu said.

"A lie," Mengfei said without any fluctuation in her voice. "We wanted to take the chance to gather resources in the Broken Primordial Realm before the conflict in the Huang Realm broke out, but you also wanted to do the same, thinking that we would be too occupied, didn't you?"

Emperor Yanxu said nothing.

Mengfei continued to speak. "I heard that among the current generation, there is a genius sword immortal named Bao Ling. Before he even became an immortal, one of the Heavenly Lord of Numinous Treasure's four supreme swords chose him as his master. Is he in the Broken Primordial World right now?"

Grand Elder Zhang frowned upon hearing Mengfei's analysis. In her recognition, very few mortals and even true immortals would find it difficult to deal with Tianyi in the Broken Primordial World, but it was a different story for a wielder of one of the Four Immortal Exterminating Swords.

Mengfei took Emperor Yanxu's silence as an admission of guilt, and a black crystalline sword appeared in her hand.

"Hold on, don't rush!" Grand Elder Zhang cried out as Mengfei's sword arced towards Emperor Yanxu. Left with no other choice, she controlled her Ink Poem Palace to rush forward.

"Hmpf, youngsters don't know how high heaven and earth are!" Emperor Yanxu cried out and drew the Immortal Ending Sword. The law it embodied was destruction.

He cast a gaze at the ten immortal monarchs, and they quickly blocked Grand Elder Zhang's way.

"Just mere monarchs and you dare to block me?!"

The ten immortal monarchs stayed silent and formed a formation. In conjunction with their immortal qi and myriad swords, they formed the Ten Thousand Sword Formation, causing Grand Elder Zhang to be stymied.

"You even brought out the Immortal Confining Sword! It seems that you truly wanted to kill one of us today!" Grand Elder Zhang roared as she recognized the plain sword acting as the formation's anchor. With it, ten immortal monarchs were able to stall her and Ink Poem Palace. If she wasn't careful, her immortal palace might be ruined and maybe even her life.

Grand Elder Zhang glanced at the battle between Mengfei and Emperor Yanxu. Emperor Yanxu wasn't the most ancient emperor, but he was the most active one. He had already lived an impressive five hundred thousand years and was at the cusp of entering the Origin Immortal Realm. Of his three flowers, only the last one had yet to form.

Except for the Concealed Sovereign, Grand Elder Zhang thought no one could contend against him, which was why she was so surprised that Mengfei was able to contend toe-to-toe with him. Sweat dripped down her forehead upon realizing that if Mengfei hadn't appeared, this would have been the lineup she would have faced.

Shiiinnnng

Mengfei's black crystalline sword shattered after the last clash against Emperor Yanxu's Immortal Ending Sword. However, she didn't panic as the blade zeroed in on her as she controlled the sword casket to block it.

The sword casket trembled as the Immortal Ending Sword sliced into it after one strike, but the blade was stopped by the content inside.

Mengfei didn't form another crystalline sword and instead started to form several hand seals and release her essence qi. Emperor Yanxu doubled the number of sword strikes upon seeing this, but the sword casket took all the strikes.

"Rise, Tri-Unity World!"

A blue sky appeared in the Vast Void. Under it was a giant landmass filled with vegetation and beasts, and there were even human cities scattered throughout. This wasn't a true world or realm but the result of Mengfei's accomplishment in formations using the Law of Heaven, Earth, and Man.

Emperor Yanxu grunted as he felt the suppression against him that only realmlords could accomplish. He couldn't help but praise Mengfei. "Amazing, to be able to create a pseudo realm and control it like a realmlord. You are the only one this old man has seen in all my years. Unfortunately, you aren't a member of the Numinous Sword Sect and will have to fall here!"

A black aura encased the Immortal Ending Sword in his hand, and he thrust it towards Mengfei. Nothing seemed to be able to halt his sword strike as even the space of the Tri-Unity World twisted and shattered.

Mengfei's body froze as if trapped in a shackled coffin, but she controlled the sword casket to fly in front of her. Emperor Yanxu ignored it and continued piercing. His blade slid through the sword casket like a hot knife through butter.

But the scene of him piercing Mengfei's heart through the sword casket did not appear. Instead, his sword hit something solid, and whatever remained of the sword casket struck Mengfei due to the momentum of his strike.

After retreating a few hundred meters, Mengfei coughed but was otherwise unharmed. She glanced at the sword casket to see a black aura eroding it.

She reached into the sword casket and grasped onto its content, and pulled, revealing a plain sword filled with a slaughterous aura that caused the light to dim.

It wasn't an illusion, as the moment Mengfei grasped the sword, the Tri-Unity World seemed to have changed. Dense slaughter intent filled every nook and cranny. The false animals started to bite and kill each other with abandon, and the fake human cities also suddenly started to war with each other.

Emperor Yanxu couldn't help but frown upon recognizing the sword in Mengfei's hand. "Where did you get the Immortal Slaughtering Sword?"
