The deeper you go into the Dead Ze, the more treacherous the environment becomes.

But today, in the depths of the Dead River, there is no time when a thick white fog appeared, and this thick fog is pure white in color, which is not at all like what the depths of the Dead River should be.

Mu Bai continued to go deeper into the Death Swamp along the dense fog, looking for that giant tree that was incredible in the heavens and all worlds!

According to the description in the original book, the giant tree is six feet tall at the root alone, and it is called the tree wall. It is as huge as a mountain peak, like a building tree in myths and legends, connecting the heavens and the world.

Mu Bai is still quite interested in giant trees, because such a giant tree can never be native to the Zhuxian World, just like there can never be a peak of more than 10,000 meters on the earth, because the gravitational pull of the earth determines the height of the mountain peak.

"In other words, what kind of existence is the Heavenly Emperor of this Immortal World?" According to the description of the original book, the Heavenly Emperor's Treasury is the place where the Heavenly Emperor cultivated before he attained enlightenment, but throughout the original work, the legend of the Heavenly Emperor is only a piece of the Heavenly Emperor's Treasury, and there is no mention of it elsewhere.

For example, Qingyunmen worships the three Qings of the Daomen, the demon cult believes in the Holy Mother of the Netherworld and the King of Tiansha, and Tianyin Temple respects Amitabha Buddha. The Wu clan in southern Xinjiang also has its own gods. On the contrary, it is the Emperor of Heaven, who has almost no sense of existence, and it is very unreasonable.

At this time, Mu Bai floated in the air, and saw a faint glimpse of the tree wall in the distance, and a smile suddenly appeared on his face.

Along the tree wall, it didn't take long for Mu Bai to see the incredibly huge tree roots, and in front of it, humans were like ants.

Mu Bai opened his copy talent, but it was empty, this giant tree was just a giant tree, not an imaginary tree demon, and naturally there was no talent. Seeing this, Mu Bai did not continue to stay, the purple light under his feet lit up, and Lei Jijian dragged Mu Bai to rise quickly, quickly sinking into the layers of dense fog.

Along the huge trunk, Mu Bai continued to fly in the dense fog for more than an hour, and he still couldn't see the crown of the giant tree, making people wonder if the giant tree would really be connected to the heavenly realm.

"This giant tree is really unreasonable, unless...... Before the current civilization appeared, there was a glorious cultivation civilization, otherwise there would be no way to explain the existence of this giant tree! Mu Bai muttered to himself, and finally let him pass through the fog and come to the clouds, allowing him to see the full appearance of the giant tree!

The sky was blue, cloudless, and the sky was clear, and the white mist under his feet was boundless, wrapping around the giant tree in front of him, and the closer he got to the giant tree, the thicker the fog became.

Imagine how unimaginable it is that above 10,000 meters in the sky, there is still a big tree towering in the clouds, like a majestic mountain!

"This giant tree makes me even more sure that this world of Zhuxian is not simple!" Mu Bai smiled slightly, and continued to walk towards the top of the giant tree, at this time, he found that the further he flew, the trunk of the giant tree gradually became smaller, and later it had become dozens of zhang in size, but despite this, it still looked shocking.

After flying some distance again, Mu Bai suddenly lit up, but it was the giant tree that split into two forks here!

Mu Bai's purpose here is the treasure house of the Emperor of Heaven, naturally it is to the left side of the fork, fly for a long time, at the end of the fork, he actually saw a stone gate, five zhang high, three zhang wide, embedded in the trunk of the tree, surrounded by countless vines and flowers, leaving only the thick boulder in the middle, engraved with the four big characters of the ancient seal.

"The Emperor's Treasury"

Faintly, there was a voice like Huang Zhong Da Lu, echoing in the blue sky, shaking the heart.

Mu Bai looked excited, the third volume of the Book of Heaven finally made him wait!

Mu Bai subconsciously looked at the sun, and it was recorded in the original book that when the sun shone on the word "sky" on the stone gate, the door of the Heavenly Emperor's treasury would be opened when it was opened, and the opening time was extremely short.

"Looks like we'll have to wait a while!" Mu Bai said secretly, sat cross-legged in front of the stone gate, and waited silently. After a while, a voice suddenly came from below, and Mu Bai opened his eyes to see that it was Tian Ling'er.

"Senior brother, senior brother, help your life, Xiao Fan and Senior Sister Lu were chased and killed by a big black snake......" Tian Ling'er saw Mu Bai and immediately exclaimed in surprise.

Mu Bai's face changed, and just as he was about to get up and fly down, the trunk of the tree shook violently, as if a prehistoric giant beast was crashing into the giant tree.

"The Black Water Snake is here!" Mu Bai's face was straight, the Lei Ji Sword in his hand had already been held, and he put on an attack posture, and sure enough, the clouds and mist below dispersed, revealing the figures of Xiao Fan, Lu Xueqi, Lin Jingyu and others, and behind them, a huge giant snake opened its bloody mouth, choosing people to devour!

"Haha, Blackwater dude, there's no need to be so enthusiastic when you meet again, right?!"

Mu Bai laughed, and the thunder sword in his hand came out, and the sword led the dragon trick to be cast instantly, and a shocking dragon roar resounded through the clouds, and the black water snake was immediately suppressed in place!

Taking advantage of this time, Xiao Fan and Lu Xueqi finally got rid of the attack range of the Black Water Snake and fell to Mu Bai's side, with the surprise of the rest of their lives: "Senior brother-"

Mu Bai nodded at everyone, still looking at the Black Water Snake vigilantly, there was no doubt that the Black Water Snake was his biggest opponent in the third volume of the Book of Heaven this time.

Sure enough, the stegosaurus chant didn't suppress the Black Water Snake for a few seconds, and soon the Black Water Snake continued to rush up, roaring at Mu Bai, and had a lot of opinions about Mu Bai! After seeing the stone gate of the Emperor's Treasury that day, he was even more crazy, and he rushed directly towards Mu Bai!

"You go to the side, that black water snake is targeting the things in the stone gate!" Mu Bai reminded Xiao Fan and the others that the horizontal sword faced the Black Water Snake, and the long sword in his hand suddenly burst out with an incomparably powerful sword momentum!

Xiao Fan and the others also understood that with this black water snake present, they almost couldn't get the legendary treasure, and they retreated to the side.

"Senior brother, be careful yourself!" Tian Ling'er advised.

Mu Bai replied: "Don't worry, I am an old friend with the Black Water Snake!" ”

With the shift of the daylight, the four ancient seal characters of "Heavenly Emperor's Treasure House" on the stone gate sparkled in the sun, in the face of this abnormal situation, the black water snake looked even more crazy, and even collided directly with Mu Bai, and did not dodge or dodge Mu Bai's attack, but he planned to fight to get injured and snatch the treasure!

Suddenly, I saw the huge mouth of the black water snake open, and in the air, it suddenly smelled fishy!

"Roar—"

Mu Bai's face was straight, and with a wave of his hand, there were thirty-six Xuan Ice Sword Qi, forming a complex formation, blasting towards the Black Water Xuan Snake, not seeking merit, but hoping to be able to block the Black Water Xuan Snake for a moment!

At this moment, a dull roar came from above the stone gate of the Heavenly Emperor's treasure house. It is precisely because of the sunlight in the sky that shines on the top horizontal of the word "sky" in the four-character ancient seal of the "Heavenly Emperor's Treasure House".

The next moment, the huge Heavenly Emperor's treasure house stone door opened, and the golden light covered the heaven and earth, so brilliant that the naked eye could not see it directly! Mu Bai's expression was overjoyed, and he didn't want to think about it, he slashed out a sword at the Black Water Snake, and the thunder and lightning shrouded the Black Water Snake, and then quickly rushed into the Heavenly Emperor's Treasury.

At this moment, a cold blue light suddenly flourished, and it was Lu Xueqi who controlled the Tianya Divine Sword and also rushed towards the Heavenly Emperor's Treasury, and at the moment when she was about to rush into the Heavenly Emperor's Treasury, a huge black shadow hit her hard......
