I don't know how many times larger the Ancient Hall is than Yangcheng, and the spacious streets are full of people, and the sounds of hustle and bustle gather together, rush into the sky, and finally spread out well.

"There are still three days, and it is time for the Ancient Secret Treasure to open, and now there are only two Ancient Keys in the Ancient Palace, respectively in the hands of the Honghuang Dynasty and the Youquan Dynasty."

"It is said that the remaining two ancient keys are in the hands of a low-level dynasty, it seems to be called the Great Yan Dynasty, do you say that they are afraid that the ancient keys will be robbed, so they dare not appear in the ancient palace?"

"You think too much, the brothers Lin Mu and Lin Dong of the Great Yan Dynasty have destroyed the Demon Rock Dynasty, it is said that one of the ancient keys was snatched in the hands of the Demon Rock Dynasty, with their strength, how could they be afraid."

Next to a tea shed on the side of the street, there sat five figures, and they heard all these discussions on the street.

These five figures are Lin Mu, Lin Dong, Qing Tan, Xiao Lei, and Xiao Yan, who has just transformed into a shape.

"Big brother, I felt two subtle fluctuations in that direction, and the other two ancient keys should be there." Lin Dong looked at the golden temple in the center of the city.

Unlike the hustle and bustle of the city, the palace was rather secluded, and it was inhabited by some powerful and high-ranking dynasty.

"Let's go over, they must be waiting for us." Lin Mu said lightly, then stood up and walked towards the central hall.

In the central hall of this palace, there were many Dao figures at this time, and these people were all well-known dynasties and powerhouses in the Northwest Region.

On the front side of the main hall, there are two figures, these two people are obviously the representatives of the two most powerful groups in the main hall.

On the left is a strong man, his exposed skin is covered with tattoos, and there is a vague savage aura coming out, and he sits there quietly, like a wild beast.

The one on the right is a woman in a purple and black dress, the woman's appearance is cold, her long hair is black, and her slender figure is also a beautiful scenery in the hall.

"The two remaining Ancient Keys have finally appeared." The woman in the black dress suddenly raised her eyes and muttered.

The Ancient Keys can sense each other within a certain range, and Lin Dong can sense their existence, and they can naturally sense Lin Dong's arrival.

"Lin Mu and Lin Dong brothers can destroy the Demon Rock Dynasty, they do have some ability, but it is a bit too much to occupy two ancient keys at the same time, and one must be handed over to us." There is a person on the right side of the main hall, and looking at its location, it should be a representative of a high-ranking dynasty.

"That's right, you have to hand it over." The other chimed in.

"Who wants the Ancient Key in our hands?"

A faint voice came in from outside the hall, and then Lin Mu and the five people walked in slowly, their eyes swept over the person who had just spoken, with a smile on their faces.

"If you know each other, hand over an ancient key, otherwise you may not even be able to keep an ancient key." The man stood up, judging from the fluctuations of the Yuan Force emanating from his body, it was the One-Yuan Nirvana Realm, and it was no wonder that he had the courage to snatch something from Lin Mu and Lin Dong's hands.

"You want the ancient key in my hand, do you deserve it?" Lin Mu said disdainfully.

"I'll let you see if I'm worthy." The face of the person in the One-Yuan Nirvana Realm was gloomy, and he suddenly stepped on his feet, and his body swept out violently, rushing towards Lin Mu.

There was no need for Lin Mu to do anything at all, Xiao Lei stepped forward, a touch of ferocity appeared in his eyes, and he punched over.

The two fists collided, and there was a muffled bang, and the little thunder did not move, but the other party shot backwards like a cannonball, as if a sound of bones was also heard.

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

"Does anyone else want the Ancient Key?" Lin Mu smiled faintly.

"Don't." One by one, they shook their heads vigorously.

"Farewell, I'll come back again in three days." Lin Mu said with a smile, and then left with Lin Dong and the others, and when he left, he glanced towards the south of the main hall.

In that direction, there was a tall tower, and at this time, several figures were standing on top of the tower, and one of them was really Mu Hongyan that Lin Mu had seen at the beginning.

"He seems to have spotted us." Mu Hongyan said to a handsome man dressed in white.

"Lin Mu's strength is stronger than expected, I may not be able to deal with that person just now, and Lin Mu is obviously stronger than that person." The man in white sighed.

"Even Big Brother Liu Bai is not his opponent, is he really a person from a low-level dynasty?" Mu Hongyan said in surprise.

"I'm afraid this ancient secret treasure battle is going to be lively." Liu Bai said with a smile.

"There are also people from the southwest region, and it is said that there are still people who are qualified to enter the Nirvana list, and they are indeed going to be lively." Mu Hongyan muttered.

Three days passed quietly, and when the morning of the fourth day came, the huge city of the Temple of the Ancient was completely rioted.

In the center of the city, there is an altar-like building, and the surrounding area of the building is painted with some strange runes, and faintly, energy fluctuations are emanating.

This is where the Ancient Vault opens.

When Lin Mu arrived, there were already two figures waiting next to the altar, it was the two people sitting on the side of the main hall on which day, the strong man was called the leader of the Honghuang Dynasty, called Hongzong, and the woman was called the leader of the Youquan Dynasty, called Youqing.

When all the four ancient keys arrived, everyone's eyes became hot.

"Brother Lin Mu, Brother Lin Dong, everyone is waiting in a hurry, since the people have arrived, let's open the ancient secret store." Hong Zong smiled at Lin Mu and Lin Dong.

"Okay." Lin Mu agreed, and flew to the side of the altar with Lin Dong.

The four of them gathered together and took out the ancient keys at the same time, and 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.

The moment the giant gate opened, the endless sea of people surged like a torrent, overwhelmingly rushing towards the giant gate, completely ignoring the danger behind the giant gate.

Lin Mu and Lin Dong put away the ancient key, and then with a move of their hands, Qing Tan and the others came behind them.

"Let's go in too." Lin Mu Road.

The five Lin Mu people merged into the mighty sea of people and entered the ancient giant gate.

The moment he entered the ancient giant gate, Lin Mu sensed a tearing force, and wanted to separate them, the five of them held hands and wrapped themselves with Yuan Force to resist this tearing force.

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