"That's a good question."

Master Sumeru squinted his eyes and said in a deep voice, "At first, Poor Dao was also extremely puzzled by this. ”

"After half a year of exploration and searching, I finally made an inference."

"What is buried in this tomb is not the remains of the immortal Hades."

"Rather, it's an earth-shattering and terrible secret."

Lu Ming and Xiao Yi were stunned when they heard this, and they were so nervous that they held their breath.

"Dare to ask Sumeru seniors, what is the secret?"

"This, the poor road is unknown."

The Venerable Master Sumeru sighed slightly, and said helplessly, "But the poor Dao can be sure that behind this secret, there must be a great deal of stake. ”

"Even ...... It may threaten the safety and survival of the Tianxuan Continent. ”

Lu Ming was silent for a long time, and his heart fell into deep thought for a while.

The Venerable Master Sumeru smiled lightly and asked, "Lu Xiaoyou, you just said that you came to the Tomb of Hades to find a treasure?" ”

"I don't know what a treasure can make you take such a big risk."

"Sumeru's seniors and juniors are just hearsay, and they are not sure."

Lu Ming asked tentatively, "I don't know if the predecessors know that there is a treasure called the Ancient Divine Emblem?" ”

"I've heard a little."

The Venerable Master Sumeru nodded thoughtfully, "According to legend, this treasure originated from the Ancient Emperor and was left near the Demon Town Mansion before it was about to die. ”

"If this legend is true, then the only possible hiding place is probably this tomb of Hades."

As he spoke, the Venerable Master Sumeru smiled faintly, "It seems that you and I can go together." ”

"Let's see if Poor Dao will figure out the secret first, or if you will find the Ancient Divine Emblem first."

"Sumeru senior, I'm afraid it must be me who won."

Lu Ming also grinned and said, "Because I came to this Hades Tomb on this trip, but there is a guide." ”

"Oh?" The Venerable Master Sumeru raised his eyebrows, his face showing interest.

Lu Ming unhurriedly held the six compasses in his palm, and pulled the pointer towards the hungry ghost path again.

A cloud of black mist emerges from the compass, and the gravedigger reappears.

At this time, he still maintained the posture of holding his head in his hands, lying on the ground and shivering.

"Monsters!"

Without waiting for Lu Ming to speak, the Venerable Master Sumeru raised his sword eyebrows upside down, and instantly took out a rune paper from his waist.

Faced with the murderous spell, the gravedigger shuddered with fright.

immediately crawled behind Lu Ming and wailed, "Master save me!" ”

This ...... It's really embarrassing to yourself.

Lu Ming was embarrassed for a while, hurriedly raised his hand to stop the Venerable Master Sumeru, and said with a wry smile, "Senior Sumeru is slow. ”

"This isn't an ordinary demon, it's a slave I've summoned."

"He has a unique ability to perceive any tomb in the world, which can help us move freely in this tomb of Hades."

The Venerable Sumeru frowned, and then slowly retracted the charm.

"Lu Xiaoyou, you can actually summon a monster for your use?"

"Dare to ask what kind of treasure is this compass in your hand?"

"Uh, that's it......"

Lu Ming scratched his head and sneered, "This thing is an ancestral treasure left to me by my father and mother." ”

"I don't know the name or the origin, but I know that it is indeed very practical."

The Venerable Master Sumeru still had doubts in his heart, but it was not good to ask any more.

Immediately, the gravedigger carried two shovels and walked in the front to lead the way.

Lu Ming and Master Sumeru followed vigilantly, always on the lookout for everything.

Along the way, they encountered three more riots, and there were thousands of ghouls.

But they were all easily killed by Lu Ming and Master Sumeru, and they did not pose the slightest threat to them.

Under the guidance of the gravedigger, the two rounded the road and shuttled dozens of miles away.

After walking a stick of incense, he stopped in front of a magic circle.

"Master, this is it!"

The gravedigger said in a deep voice, "This place is the end of this ancient tomb. ”

"All the treasures in the tomb must be hidden under this magic circle."

"But this array must be left by a master, and the power is quite terrifying."

"With my ability, I'm afraid I won't be able to help the master......"

"You've done a great job."

Lu Ming nodded and said lightly, "Go back, if there is any trouble, I will summon you out." ”

"Master, that ......"

The gravedigger opened his mouth, wanting to ask Lu Ming about the reward he had promised earlier.

However, when he saw the Venerable Master Sumeru standing aside with an unkind face, he remembered that he had fled for his life as soon as he encountered a ghoul before.

The gravedigger didn't dare to ask for any reward for a while, and immediately turned into a wisp of green smoke and floated into the six compasses.

"Lu Xiaoyou, this formation is not simple."

The Venerable Master Sumeru squinted his eyes and looked at it for a moment, then said in a deep voice, "If I'm not mistaken, this array is called the Yin and Yang Double Killing Array, and it has two array eyes. ”

"If you want to crack this array, you must use powerful magic powers to destroy the Yin and Yang Array Eyes at the same time in an instant."

"If you break one of the formations first, or if the power is uneven, the attack ban of the Yin and Yang Double Killing Array will be triggered."

"At that time, you and I will have no way to go to heaven and no way to enter the earth."

"As long as there's a problem to solve, that's not a problem."

Lu Ming grinned and said confidently, "Senior Sumeru, you just have to use your most powerful attack. ”

"The younger generation will definitely not hold you back."

The Venerable Master Sumeru frowned slightly, visibly hesitating.

His cultivation was already half a step in the Supreme Realm, nearly an entire Great Realm stronger than Lu Ming.

Lu Ming was so confident that he could keep up with his own power.

Is it blind arrogance, or is it a big deal?

But he only hesitated for a moment, then chose to trust Lu Ming, and nodded slightly, "Okay." ”

Immediately, the Venerable Master Sumeru took out a piece of talisman paper, lit one end of it, and threw it into the air.

"Lu Xiaoyou, you first condense the true yuan in advance, and prepare the divine power you will use."

"At the moment when this rune paper burns out, you and I will attack at the same time to crack the Yin and Yang Double Killing Array!"

Immediately, Master Sumeru and Lu Ming jumped forward, respectively located in the Yin and Yang Formation Eyes in the formation.

The Master of Sumeru had two talismans between his two fingers, which were inferior-grade immortal talismans filled with spiritual mist.

Lu Ming, on the other hand, pulled the pointer in advance and moved the pointer to the position of the animal path.

Both of them stared intently at the rune paper in mid-air, watching the rune paper being burned by the fire little by little, so nervous that they didn't even blink their eyes.

After about three minutes, the rune paper was completely burned.

At the moment when they were reduced to ashes and scattered, Lu Ming and the Venerable Master Sumeru shouted loudly at the same time.

"Wind and thunder break the void talisman, drive away!"

"Animal Dao, the divine beast is strengthened, and the green dragon is beside you!"

The Venerable Master's spell instantly turned into thunder and lightning, and fell from the sky with a loud bang.

The short sword in Lu Ming's hand turned into a hundred-foot-long blue light giant sword.

The thunder and the sword light plummeted down at the same time, and it slammed into the Yin and Yang Array Eye with precision.
