More than a dozen Abilities slashed skeletons to pieces in front of them, and three or four Fire-based Abilities followed, unleashing abilities that burned the reborn skeletons to pieces.

Two hours later, all skeletons on the second floor were completely wiped out.

Mu Tian's physical strength had also recovered to the eighth layer, which was enough to fight normally.

"Your Highness, send nine more people to press those nine snake eyes. ”

"These skeletons have been wiped out, and nothing should happen anymore. Mu Tian gestured.

John nodded and sent out nine Adepts again, pressing the trap at the same time.

"Squeak ......"

Like a mechanism on the first floor, the stone door to the third floor soon opened automatically with the sound of a burst of gears.

"Let's go, we're running out of time. Mu Tian saw the stone door open and strode inside.

One-third of the oxygen in the oxygen cylinder had already been consumed, and if they didn't go out before the oxygen was exhausted, Mu Tian and the others would have to breathe the air inside the pyramid.

Mu Tian did not have any toxin resistance, and if he breathed these poisonous gases, he might have any adverse reactions.

Mu Tian didn't dare to bet on this hand.

John and the others also understood this truth, and they didn't dare to delay at all, and hurriedly kept up with Mu Tian's pace.

"Watch your step, don't step on the trap!" shouted John's endnote.

Mu Tian's speed didn't dare to be too fast, so he could only probe step by step.

The closer you get to the fourth layer, the more dangerous it will definitely be, there's no doubt about it.

Although they were very anxious, everyone could only patiently move forward step by step.

"Boom la la ......"

"Is this ......?" Mu Tian pricked up his ears and listened carefully to the sound.

After walking a few steps further, Mu Tian and the others saw a panoramic view of the third floor.

"Is this an underground lake?" Trista said in shock.

"Mr. He, this water is living water, it shouldn't be stagnant water!" John endnote picked up a little water in his hand and brought it to his eyes to take a closer look.

The living and stagnant water are still easy to observe, and John's endnotes can be seen at a glance.

Under normal circumstances, the groundwater is basically about 50 meters deep, and a few are above 100 meters, but the desert near Cairo is relatively dry, and the groundwater level is 700 meters.

In other words, Mu Tian and the others are now more than 700 meters underground, and the underground part of this pyramid is at least four times as much as the ground part!

"Your Highness Endnote, are you sure that this pyramid has a fourth layer?" Mu Tian was suspicious of John's endnotes for the first time.

This third layer has been encroached upon by groundwater, and if there is a fourth layer, it should be in the rocky layer beneath the groundwater.

And with ancient construction techniques, can it really be done to such an extent?

Even with a modern engineering system, it is difficult to build such a project, right?

"If there is no coffin on the third floor, then there should be a fourth, right?"

What a few people have experienced today is too mysterious, and John's endnotes also have a trace of doubt about the records in ancient books.

"Anyway, let's keep looking and see if we can find our way down. Mu Tian sighed.

All this that has been experienced so far is really too much beyond Mu Tian's cognition.

"Ahh

"Help!

"Brute, let him go!" Gulagas was furious, the yellow sand in his hand condensed, and he slapped his palm towards the lake.

There was a crisp sound of "click......, and a B-class ability was bitten off directly from the waist, and the lower half of the body had been taken away by the monster, and the upper body was left on the shore, and it seemed that he would definitely not survive.

"What's the situation?" Mu Tian hurriedly asked.

"A big snake suddenly came up and I didn't react at all. Gulagas looked at the half-cut corpse on the ground in chagrin.

"Arafat, let the fire adepts cremate his body. John endnote frowned and commanded.

As a leader, if you are sad because of a person's sacrifice, then he is not worthy of being a leader.

As the eldest prince, John naturally has extraordinary willpower.

"Yes. With a wave of his hand, Arafat dragged half of the body of the Adept to a fire-type Adept.

The Fire Adeptus decisively cremated him and put him in a small box that he carried with him.

"I'll go down and meet it, and you wait on the shore. Mu Tian took off his shirt and jumped off the lake.

Mu Tian is negative with electric eel genes, and there is no difference between water and land.

Mu Tian is confident enough to meet this big snake.

"This is ......!" Mu Tian's eyes widened, and he looked at the big snake in front of him that was devouring the corpse.

A pair of eyes were red, even to the point of flooding.

Look at the appearance of the big snake again, it is the one that Mu Tian saw on the second layer of murals!

"Roar!" The big snake roared when he saw Mu Tian coming up, staring at Mu Tian deadly.

"No matter what you are, come and fight!" Mu Tian held the Ice Spirit Knife in his hand and headed straight towards the big snake.

If this snake is really the one on the mural, then this snake should have been alive for two thousand years!

"Mr. Guragas, Mr. Hetian, he ......" John Footnote saw the churning water of the lake, and a trace of worry flashed in his eyes.

The big snake John also saw the endnote, a head is more than ten meters long, and John's endnote is not very sure whether Mu Tian can defeat this big snake.

"Don't worry, Your Highness, Mr. He's strength is very strong, there should be no problem. Gulagas reassured.

He is a yellow sand powerhouse, and what he is most afraid of is water.

Therefore, he had no way to go down to help Mu Tian at all.

"I hope so, if Mr. He has an accident, we really can't get out. ”

......Suddenly, a soft sound came from the rock wall, and a large bird with black wings jumped into the lake.

"This seems to be the bat on the mural?" said Arafat, somewhat confused.

Arafat had also looked closely at the mural and was slightly familiar with the size of the big bird.

"Bang!" In the water, Mu Tian's ice spirit knife slashed at the top of the big snake's head, but it didn't cut into the flesh, but there was a sound of gold and iron clashing.

"Although the strength of this big snake is slightly lower than mine, this body is too thick. Mu Tian retreated a little helplessly.

This was Mu Tian's tenth attack, but he couldn't break through the big snake's defense every time.

......Several terrible chirps came from above Mu Tian's head, and when Mu Tian looked up, he saw a huge bat rushing straight into the water and clamping down on the seven inches of the big snake.

"This seems to be the big bat on the mural?" For a moment, Mu Tian was dumbfounded, and even forgot to attack.

Bats and snakes were constantly fighting, and the lake was stirred and splashed everywhere.
