Why did you provoke her? Even Heaven itself is afraid of her.

Chapter 307 The Millennium Pact

"Senior, can you help us fuse the national treasure now?" Ling Yun asked.

Gongshu No. 7 nodded and said, "Of course. Bring out the national treasure."

Ling Yun and the others quickly took out their national treasures and handed them to Gongshu No. 7.

Gongshu No. 7 took the national treasures, examined them carefully, and then said, "These four national treasures contain great power. It will not be an easy task to fuse them together. I need some time to prepare."

"How long will it take, senior?" Qin Feng asked.

Gongshu No. 7 thought for a moment and replied, "It will take about three days. You can rest here during these three days."

Everyone nodded, and then, under Gongshu No. 7's arrangement, they settled down in a nearby cave.

During these three days, the group rested while searching for materials in the forest.

They hope to find materials that can help with the integration of the national treasure and increase the success rate of the integration.

Three days later, Gongshu No. 7 was finally ready.

He called everyone to his side and then began to fuse the national treasure.

Gongshu No. 7 placed the four national treasures into the refining furnace and began to refine them with a strange fire.

The national treasure began to emit a dazzling light, and the four powers gradually merged together, forming a powerful aura.

After much effort, Gongshu No. 7 finally succeeded in fusing the four national treasures together.

A new cosmic treasure appeared before everyone.

This is a precious sword called the Heaven-Slaying Sword.

This Celestial Treasure, the Heaven-Slaying Sword, exudes a powerful aura, giving one a sense of unparalleled strength.

"This is the fused Cosmic Essence Treasure, the Heaven-Slaying Sword. It contains immense power and will surely help you break the seal that the Black Hole Saint Lord set up outside the Dark Abyss," said Gongshu No. 7.

Everyone looked at the primordial treasure before them, their hearts filled with joy.

"Thank you for your help, senior." Ling Yun and the others thanked Gongshu No. 7.

Gongshu No. 7 waved his hand and said, "No need to be polite. You bear the heavy responsibility of eliminating the Black Hole Saint King, so you must be careful."

Everyone nodded, then bid farewell to Gongshu No. 7 and left the Misty Forest.

They arrived at the outer edge of the Dark Abyss with the new Cosmic Essence Treasure, the Heaven-Slaying Sword, intending to break the seal reinforced by the Black Hole Saint King and leave the Dark Abyss.

Ling Yun and the others stood on the outer edge of the Dark Abyss.

Gazing at the seal before him, which had become even thicker and exuded an eerie aura after being reinforced by the Black Hole Saint King, his expression was solemn yet carried a hint of unwavering determination.

"This is it. This seal is much stronger than before."

Ling Yun gripped the Heaven-Slaying Sword tightly in his hand, his eyes burning as he stared intently at the seal, seemingly trying to find a flaw in it.

"With Sister Lingyun's Heaven-Slaying Sword, we will definitely be able to break the seal." Qin Feng took a deep breath, encouraging himself and his companions.

Lin Ximeng stood to the side, her eyes closed, a faint blue light emanating from her body. She was using her expertise in perception techniques to try and find the weak point of the seal.

"The energy fluctuations of this seal are very complex, but I seem to have found a point."

She slowly opened her eyes, a glint of shrewdness flashing within them.

Chu Yao and the envoy from Dongling Kingdom were also on high alert.

Although they did not possess the same level of cultivation and combat ability as Ling Yun and the others, they were all mustering their strength and ready to provide support at any time.

Ling Yun nodded and looked at Qin Feng.

"Qin Feng, just like Lin Ximeng said, we'll attack that node. You use the power of Hongmeng to assist me and enhance the power of the Heaven-Slaying Sword."

Then, Ling Yun gripped the Heaven-Slaying Sword with both hands and continuously poured his own power into it.

Qin Feng activated the Primordial Chaos Power within his body, and golden rays of light wrapped around the Heaven-Slaying Sword, making its blade even more dazzling.

"Break!" Ling Yun shouted, thrusting the Heaven-Slaying Sword toward the seal's node.

A dazzling light flashed, and the Heaven-Slaying Sword collided with the seal, producing a deafening roar.

The powerful impact caused the surrounding air to vibrate, creating a strong wind.

However, the seal only developed a tiny crack and quickly returned to normal.

"This seal is even stronger than we imagined." Ling Yun frowned, secretly surprised.

"It's alright, let's continue. I refuse to believe we can't break through it." Qin Feng gritted his teeth, gathered his primordial power once more, and prepared to launch the next attack.

Just as everyone was preparing to attack again, a powerful dark force suddenly surged out of the seal, transforming into countless black tentacles that attacked them.

These tentacles moved incredibly fast, arriving in front of everyone in an instant.

"careful!"

Ling Yun shouted and swung the Heaven-Slaying Sword to sever the approaching tentacles.

Qin Feng and Lin Ximeng also took action to defend against the tentacles' attacks.

Chu Yao and the envoy from Dongling Kingdom hid behind the crowd, looking for an opportunity to assist in the attack.

Black tentacles surged forth relentlessly, and the group gradually found themselves unable to resist them.

"This won't do. We must find the seal's weakness as soon as possible and strike with all our might," Ling Yun said anxiously.

Lin Ximeng closed her eyes again, concentrating her mind to perceive the seal.

“I feel that the power of the seal is constantly flowing. We need to wait for the gap in its power conversion, at which time the seal will be relatively weaker.”

Upon hearing this, everyone fended off the tentacles' attacks while waiting for the opportunity Lin Ximeng had mentioned.

Finally, Lin Ximeng opened her eyes and shouted, "Now!"

Ling Yun and Qin Feng exerted their power simultaneously. Ling Yun unleashed the full power of the Heaven-Slaying Sword, while Qin Feng poured all of his Primordial Chaos Power into it.

An unprecedentedly powerful beam of light shot towards the seal.

This time, the seal trembled violently, and the cracks continued to widen.

With a loud bang, the seal was finally broken open.

"Success!"

The crowd cheered and, without taking a break, quickly passed through the broken seal and left the Dark Abyss.

When they stepped onto the familiar interstellar universe once again, a complex mix of emotions welled up in their hearts.

There was joy in leaving the Dark Abyss, but also worry about facing the true form of the Black Hole Saint King.

"Let's split up next!" Lin Ximeng suggested to Ling Yun.

Ling Yun looked at Lin Ximeng and asked, "What do you want to do?"

Lin Ximeng replied, "I will contact the various universe lords and ask them to refine the new Cosmic Essence Treasure as soon as possible. You two go to the outer edge of the black hole universe and retrieve the Interstellar Universe Lord Supreme Bone that originally belonged to you!"

Ling Yun asked, "How long do you need?"

Lin Ximeng replied, "Based on the interstellar universe's operating cycle, it would take at least five hundred years."

Ling Yun nodded and made a promise to Lin Ximeng: "A thousand years from now, you will bring all the interstellar universe lords and cosmic treasures to the outer edge of the black hole universe to meet with us."

"it is good!"

The three of them then went about their separate activities.
