"I'll let you see if I'm worthy."

The face of the person in the Duality Nirvana Realm was gloomy, and he suddenly stepped on his feet, and his body swept out violently, rushing towards Lin Dong.

"Where to go back and forth! Come back and accompany Shi Kun! ”

Lin Dong directly flicked his spiritual power, and he slammed it into the palace wall, and the sound of his bones breaking resounded in the hall.

Seeing this scene, many people's faces showed shocked expressions, and the original greed in their eyes disappeared.

"Does anyone else want the Ancient Key?"

"No, no." One by one, they shook their heads vigorously.

No one dared to offend Lin Dong who killed the Duality Nirvana Realm in seconds, at least not in the High Dynasty.

"Since you don't want it, then give it all to me!"

Lin Dong's main purpose in coming this time was to get all the four ancient keys in his hands, so that the other four people except him could obtain the inheritance of the four great Xuanzongs.

The leader of the Honghuang Dynasty is called Hongzong, and the woman is called the leader of the Youquan Dynasty, called Youqing, they are all dualistic Nirvana realms, and when they heard Lin Dong's words, their faces were ugly, and they were not sure to fight against Lin Dong.

"Lin Dong, we have seven high-level dynasties here, you have to think clearly." Hong Zong stood up and said.

"Don't worry, I think very clearly, as long as you give me the key, no one will get hurt."

Lin Dong directly used the spiritual power of almost the Eightfold Heavenly Rune Master to suppress the leaders of the seven high-level dynasties of the Duality Nirvana Realm.

Even if the seven people were under the pressure of Lin Dong's scattered spiritual power, they seemed to be carrying tens of millions of catties of mountains on their backs, and a few weak ones directly spit out a mouthful of blood and fell to the ground.

"The little woman is willing to give up the key."

The woman in black was affectionate, first recognizing the situation and giving in, and then Hong Zong had no choice but to hand over the key.

"Thank you two, my Lin Dong counts what he says, and you can also enter the secret treasure smoothly, each looking for opportunities, see you in five days."

Lin Dong put away the key and left with Lin Dong.

......

Five days passed quietly.

In the early morning of the sixth day, in the center of the city, the ancient runes on the altar-like building began to stir, and the energy fluctuations spread, causing a riot in the whole city, and they all rushed to the central position.

This is where the Ancient Temple teleports to open the Ancient Vault.

With Lin Dong's arrival, everyone's eyes became hot.

Lin Dong didn't delay, flew to the altar, and took out four ancient keys, the four ancient keys reacted with each other, and one after another light emanated, enveloping the central altar.

And when the altar was completely enveloped, the faint ancient runes around the altar suddenly lit up, and then, the runes broke away from the altar, suspended in mid-air, and finally coalesced.

As these ancient runes condensed, a vast pillar of light instantly emerged, and then rushed straight above the altar.

Boom!

The pillar of light slammed into the void space, and then the space there began to ripple violently, the ripples surged, faster and faster, and finally, the light converged and turned into a huge light gate that exuded an ancient aura.

The runes flickered, and the ancient giant door also opened with a creaking sound, and suddenly, a smell that seemed to have been sealed for countless years surged open from behind the giant door.

The Ancient Treasure has finally opened.

Lin Dong put away the ancient key, and then with a move of his hand, Qing Tan and the others came behind him.

"Let's go in too." Lin Dong said.

Lin Dong and the five of them were the closest, and they directly entered the ancient giant gate.

The moment he entered the ancient giant gate, Lin Dong sensed a tearing force and wanted to separate them, the five of them held hands, and Lin Dong wrapped everyone with his spiritual power to resist this tearing force.

This tearing force didn't last long, it dissipated in about half a minute, and Lin Dong and the five of them also successfully entered the ancient secret vault.

It was a lifeless space, with a withered grayish-yellow color on the ground, and extremely violent spatial fluctuations spreading in the sky, making this space extremely unstable.

Each wave of people was teleported to a different location, and the five of Lin Dong entered the ancient secret hide, and there was no one else around.

"The space here is already in an extremely dilapidated stage, and in a hundred years at most, it will be completely destroyed, and then the secret treasure inside will disappear between heaven and earth."

The little mink appeared on Lin Dong's shoulder, entered the ancient secret vault, and took another step away from the Wheel of Life and Death Pill, and his mood slowly became nervous.

"There is a lot of ancient secret information in the spirit body I refined before, let me lead the way." Lin Dong felt the nervousness of the little mink and said with a smile.

"Hmm." Lin Dong has nothing to do.

Lin Dong was in front, and Lin Dong and the four of them followed, avoiding the unstable space in the air, and flying quickly, all the ruins on the way could not attract everyone's attention.

About an hour later, there was a rumbling sound far ahead, but it didn't look like the sound of water.

"It's a river! The Dan River composed of Nirvana! Oh my God, how many Nirvana pills are here! ”

Lin Dong and the others had already seen the Dan River in the Great Wilderness Sect, but Qing Tan had only seen hundreds of millions of Nirvana Dan in Lin Dong's Qiankun bag.

Lin Dong took the lead in sweeping towards the Nadan River, even if he had 100 million Nirvana Dan, he would not have too much.

However, when he got closer, the crimson 'water surface' composed of Nirvana Qi suddenly burst open, and a slightly illusory fiery red figure swept out like lightning and attacked the forest.

"Be careful."

Xiao Yan, who was following behind, suddenly increased his speed, and directly knocked the figure upside down and flew back into the Dan River.

"This is the Dan Spirit Corpse, the corpse is soaked in the Dan River full of Nirvana all year round, and it will produce a Dan Spirit Corpse similar to a puppet, which is very difficult." The mink gave the popular science road.

"Second brother, let's find a cultivation platform, there are generally cultivation platforms set up on the Dan River of the ancient sects, activating the available formations can not only better absorb the Nirvana Qi in the Dan River, but also protect against the harassment of the Dan Spirit Corps. Qingtan, the three of you should go too. I'll see if I can get some Nirvana Pill out. ”

Lin Dong looked at Lin Dong, who was deflated, and said.

"Okay big brother."

Everyone also knew that their strength still needed to be improved, and they flew directly in all directions of the Dan River to find the cultivation platform.

Lin Dong used his spiritual power to condense into a giant hand from a distance, split the Dan River, and then pulled it into the Qiankun bag, and the Nirvana Qi instantly condensed into the Nirvana Pill after breaking away from the Dan River, so that he could not expose the death qi and the cultivation of the Death Realm, and he could obtain the Nirvana Pill at high speed, and he would not be disturbed by the Dan Spirit Corpse.

In the time of half a pillar of incense, Lin Dong obtained 20 million Nirvana Pills, so that the Nirvana Pills in Lin Dong's hands made up for the previous consumption, and even more than a little, and returned to the level measured in 100 million, and the Nirvana Qi in the Dan River was also slightly weakened.

"Forget it, that's it, it's useless for me to keep so much of the Nirvana Pill."

After Lin Dong did the repetitive work for a while, he felt a little boring, and the Nirvana Pill was useless to him, so it was better to rest for a while.

After resting for a while, Lin Dong saw that above Lin Dong's cultivation platform, thunderclouds were gathering, and silver electric snakes were looming.

At the same time, a black Nirvana fire emerged from the body, but in a short instant, the whole person was burned red, which was the Nirvana Demon Flame that the Triple Nirvana Tribulation would have.

"The two catastrophes are the same, and the protagonists are different." Lin Dong secretly sighed.
