Regain the Saint Clan’s Secret Vault

“Your humble servant thanks you for your generous gift, Master!”

The Biyu Lin all kowtowed, each bow more forceful than the last.

Su Lang had taken money out of his own pocket to refine immortal-grade materials into an immortal array for them. What a kind and approachable master he was!

To have such a master was truly the result of accumulating virtue over countless lifetimes.

They had no idea that the immortal-grade materials Su Lang had provided were fundamentally synthesized from the materials in their own secret vault.

Of course, as the saying goes, Su Lang didn't lose out, but the Biyu Clan had truly made a killing.

“That’s enough.”

Su Lang stood up. “One of you, take me to the secret vault to retrieve the materials.”

“I will!”

Biyu Lin immediately volunteered, his face flushed with excitement.

“Then it’s you.”

Su Lang nodded. “Lead the way.”

“Your servant obeys!”

Biyu Lin was thrilled.

This was his first time serving the Master, and he felt quite honored.

Soon after.

Led by Biyu Lin, Su Lang headed to the headquarters of the Biyu Holy Clan, the Biyu Holy Nest.

As expected of a race with avian blood, even their racial headquarters was a bird’s nest.

The Biyu Holy Nest was enormous, oval-shaped, with a massive tree reaching into the sky in the center. Its overall shape resembled an open umbrella inverted between several giant peaks.

Biyu Lin also introduced Su Lang to the history of this headquarters.

It turned out to be the beloved nest of a powerful immortal bird, possessing very unique abilities that were highly compatible with their Biyu Clan.

Therefore, the Biyu Clan simply transformed it into their own stronghold.

Upon entering the Biyu Holy Nest, Su Lang indeed felt a strange energy.

However, this energy required bloodline guidance to be absorbed and integrated; martial artists of other races simply couldn't utilize it, except for those of the Biyu Clan.

Moreover, this energy within the Biyu Holy Nest was already relatively faint.

This was also why the Qiu Shui Immortal Clan and other holy clans hadn't coveted the Biyu Holy Nest, despite it being left behind by an immortal bird.

After circling around the Biyu Holy Nest, Su Lang obtained a large quantity of materials, thoroughly replenishing his own treasury.

What pleased Su Lang the most was that he acquired five Martial Saint Souls and over a hundred Martial God Souls.

The number of Martial Saint Souls was not unexpected; it was more than what the Yaochi and other clans possessed.

After all, the Biyu Holy Clan was stronger than the Yaochi Three Holy Clans, and more Martial Saints had passed away, thus more Martial Saint Souls had condensed.

Having obtained five Martial Saint Souls.

Su Lang immediately thought of his Immortal Annihilation Cannon!

At this moment, the Immortal Annihilation Cannon was at the limit of a quasi-immortal artifact; with further evolution, it could ascend to an immortal artifact!

Currently, Su Lang possessed the Sea of Sky and the Tai Chi Meteor Sun Divine Thunder, which allowed him to initially contend with Martial Immortals.

However, the Tai Chi Meteor Sun Divine Thunder was a one-time treasure; once used, it was gone.

But if the Immortal Annihilation Cannon were to ascend to an immortal artifact, then Su Lang would possess continuous Martial Immortal-level offensive power!

“System! Evolve the Immortal Annihilation Cannon!”

Su Lang secretly issued the command in his mind.

“Ding! Evolving the Immortal Annihilation Cannon requires consuming immortal-grade materials: Extreme Cold Yanqian Immortal Soil * 2, Crimson Rainbow Profound Demon Stone * 1, One Dark Dui Insect Jade * 1, Ruyi Soaring Wood * 2…

Saint-grade refining materials: Martial Saint Soul * 8, Azure Frost True Rock * 22, Fierce Wind Ghost Jade * 35, Dark Chaos Heaven Stone * 50, Blazing Flame Azure Crystal * 50…”

“What the heck, it actually needs 8 Martial Saint Souls?”

Su Lang's mouth twitched. He had originally thought the Immortal Annihilation Cannon, like the Sea of Sky, only needed five Martial Saint Souls.

At this moment, counting the five Martial Saint Souls obtained from the Biyu Holy Clan, he only had six, still short by two.

“If worst comes to worst, I’ll go find those malicious Martial Saints similar to those in the Wuyang Demonic Den, kill them, and seize their Saint Souls!”

While thinking, Su Lang began to refine the array disk for the Azure Sky Illusory Spirit Combined Immortal Array.

This was already Su Lang's seventh time refining the Azure Sky Illusory Spirit Combined Immortal Array; he was incredibly familiar with it.

However, he did not hand over all the work to the system function.

Because Su Lang intended to show off in front of Biyu Lin and the others, letting them see how an immortal array was set up.

“It’s time to set up the immortal array. Let’s go.”

Su Lang glanced at Biyu Lin. “Where do you want the array to be set up? Right here at the Biyu Holy Nest?”

“Yes, Master!”

Biyu Lin nodded and bowed, saying, “The Biyu Holy Nest is the lifeblood of our Biyu Clan, so I wish to have the immortal array set up here.”
