To be the best leader, you must also be the strongest leader!

Chapter 2497 6th Rank, 6th Grade Heavenly Secret

Watching the Crimson Dragon Demon Lord and the others ascend and depart, the Fourth Elder and the others secretly breathed a sigh of relief.

"Immediately arrange for someone to inform the sect leader of the situation here," the Fourth Elder hurriedly ordered.

“I’ll make the arrangements,” the Seventh Elder of the Sea Serpent replied.

Although they hadn't had much contact with the three demon lords, only they themselves knew the risks involved. If the three demon lords investigated carefully, they would definitely find some flaws.

However, with such a huge stake in the matter, it doesn't matter even if the other party discovers a flaw.

Meanwhile, Sun Yi was on the Eight Extremes Star with a group of top weapon refiners and formation masters, refining the latest Heavenly Secrets.

The latest Heavenly Secret combines the most advanced technologies currently mastered by the War Sect, including all the innate formation techniques that Sun Yi comprehended.

Moreover, the materials used to refine this Heavenly Secret are the most advanced materials currently available in the War Sect, and all the divine souls stored in the War Sect have been used for it.

The number of people involved in refining the Heavenly Secrets alone reached 13,000, among whom there were more than 34 top experts at the half-step Void Refinement Realm.

This was the largest and most energy-intensive weapon-forging operation ever undertaken by the War Sect since its founding.

The entire weapon-refining platform was requisitioned, and all other projects had to make way for this one.

After more than a year of refinement, the new Heavenly Secret finally took shape.

Above the largest refining fire pool on the refining platform, a massive Heaven and Earth Furnace floated silently in the air, surrounded by the top talents of the Battle Sect.

The raging purple flames were activated and poured into the Heaven and Earth Furnace, which turned purple and spread out in terrifying high temperature, but were continuously weakened by the dozens of layers of barriers outside.

Inside the Heaven and Earth Furnace, a circular spiritual artifact with 720 facets is gradually taking shape. Sun Yi and his companions are working hard to inscribe spiritual runes through the Heaven and Earth Furnace.

After an unknown amount of time, as the last spirit rune was inscribed, a glint flashed in Sun Yi's eyes, and he suddenly forced out a drop of his essence blood, which flew into the furnace of heaven and earth under the protection of his magic power.

This drop of essence blood quickly merged into the Heavenly Secret, and Sun Yi used the Blood Refining Technique to completely integrate it into the Heavenly Secret.

Soon, Sun Yi felt a mysterious connection between himself and this celestial secret, just like the natal spiritual weapon he had refined.

"I am about to complete the final sealing step. Once the Heavenly Secret is formed, it will definitely unleash tremendous power. I would like to ask all the Supreme Elders to do a good job in defense."

Sun Yi looked at the Heavenly Secrets inside the Heavenly Furnace with a serious expression. The quality of this Heavenly Secrets was definitely not low. The moment it took shape, it would surely unleash terrifying power. He needed to prepare in advance.

"Sect Leader, rest assured in refining; leave the defense work to us," Fang Bupo said earnestly.

"Okay, let's get started."

Sun Yi nodded, and then began to cast sealing spells at the Heavenly Secrets within the Heavenly Furnace.

As the final sealing spell was cast, the aura of heavenly secrets within the Heaven and Earth Furnace suddenly receded, and the next moment, a terrifying power erupted from within the heavenly secrets like a volcanic eruption.

This destructive force created an extremely terrifying shockwave, first destroying the outer Heaven and Earth Furnace, and then slamming into the outer barrier.

Boom boom boom...

The barrier surrounding the Heaven and Earth Furnace was torn apart in an instant, with more than a dozen layers shattered, but it was ultimately blocked.

Everyone breathed a sigh of relief upon seeing this, and all eyes were focused on Tianji, who was enveloped in flowing light.

At this moment, silver spiritual patterns appeared on the surface of the ten-zhang-diameter celestial mystery, and in a short while, these spiritual patterns formed a complex silver rune.

As time passed, more and more silver runes appeared, and when everything calmed down, everyone couldn't help but gasp in surprise.

"Sixth Rank, Sixth Grade!"

"We actually forged a sixth-grade, sixth-rank spiritual weapon!"

"Incredible! Unbelievable!"

"Yes, this is the human realm. The most powerful among us is only at the half-step Void Refinement Realm, yet they can forge a sixth-grade, sixth-rank spiritual weapon!"

"Great! All our hard work and effort wasn't in vain!"

"A sixth-order, sixth-grade Heavenly Secret, I wonder to what extent its computing power will be enhanced."

"This marks another breakthrough in our history of weapon crafting!"

……

All eyes were fixed on the sixth-rank, sixth-grade Heavenly Mystery in the sky, and every cultivator wore an excited expression.

Even in the human realm, it's not easy to forge a sixth-order spiritual weapon. And once a spiritual weapon reaches the sixth order, the difficulty of forging increases exponentially with each subsequent order.

There are many conditions that need to be met to forge a high-level spiritual weapon.

Factors such as the refiner's cultivation level, the temperature of the flame, the design of the spiritual weapon, and the grade of the materials all play a role. Generally speaking, it is already extremely difficult for the human realm to refine a low-grade sixth-order spiritual weapon.

However, Zhan Zong's weapon-refining technique directly broke the limits of the human realm, creating a sixth-order, sixth-grade spiritual weapon that no living being in the human realm had ever refined before.

This celestial mystery has a total of 720 faces, each with a mechanical eyeball in the center and countless mysterious spiritual patterns engraved on its surface.

This celestial secret was named the Third Celestial Secret by Sun Yi, and its main function was to assist Sun Yi in studying the innate formations of Neptune.

"Sect Leader, quickly test how much the computing power of the Third Heavenly Machine has increased," Zhang Ye said impatiently.

"Yes, let's try it quickly."

The other cultivators also looked at Sun Yi with anticipation. Based on the previous predictions from the design drawings, the computing power of the new Heavenly Machine should be ten times that of the second Heavenly Machine.

However, the exact extent of the increase in computing power still needs to be determined through formal testing.

"Let me test it out." Sun Yi was also very curious about how much the computing power of the No. 3 Heavenly Machine had increased.

He reached out and summoned the No. 3 Heavenly Secret, which flew toward him and quickly shrank into a sphere three feet in diameter, hovering above Sun Yi's head.

Sun Yi closed his eyes and his main soul entered the third Heavenly Secret.

In an instant, Sun Yi seemed to become the spirit of the No. 3 Heavenly Secret, perfectly merging with it.

Perhaps because blood refining was used in the refining process, Sun Yi was able to easily achieve a state of spiritual unity with the Third Heavenly Secret.

Under these circumstances, Sun Yi immediately began testing the computing power of the No. 3 Heavenly Machine.

The test results shocked Sun Yi; they were much better than expected.

After retrieving his main soul, Sun Yi smiled with satisfaction and said, "The computing power of the third Heavenly Mystery is fifteen times that of the second Heavenly Mystery, which is stronger than expected."

"Fifteen times, that's fantastic!"

"As expected of a top-tier sixth-grade spiritual weapon!"

"Fifteen times the computing power should be able to solve many problems."

……

"Everyone has worked hard this time. I will continue to invest in the follow-up research. You can continue to develop according to the previous plan. This time, I will take all the split souls except for the No. 2 Heavenly Secret with me. I hope to produce research results as soon as possible."

The third celestial secret has been successfully refined. Sun Yi decided to return to Neptune as soon as possible to continue his research and to understand the innate formations there.
