After Li Zhen and Princess Ao Lu rested for about an hour, they each adjusted their state to the peak, and then started to move to the Dragon Tomb in the underwater canyon. Ao Chun was waiting outside, Li Zhen and Ao Xi turned into light and rushed into the sea, went straight to the submarine canyon, and soon disappeared from Ao Chun's sight.

After flying into the canyon, Li Zhen and Ao Xi were soon shrouded in darkness, at first the two were able to see at night, but as they went deeper and deeper into the bottom of the sea, their vision began to be affected, and they didn't know how long they sank, their vision was almost completely blurred, and Ao Xi's voice sounded.

"Don't be nervous, you'll be there right away."

When Li Zhen heard this, he was stunned.

How did she know she was nervous? ’

With doubts, Li Zhen followed Ao Xi closely, and he found that Ao Xi was not affected by the darkness, which may have a lot to do with the fact that she was a dragon.

Dragons are the most powerful creatures in the world, and one of the reasons why they are powerful is that they don't need to practice, and as they get older, their strength is enough to reach heights that no other race can reach in a lifetime.

God has given them a strong body and a strong talent, but it has also given them restrictions, as the saying goes, there will be gains and losses. Dragons' fertility has always been a major flaw for them, and the long growth period is also one of the major flaws.

If it weren't for these two major flaws, the dragons would have ruled the entire desolate world long ago.

I don't know how long it continued to sink, and two points of light lit up in the distance, like a pair of eyes in the dark night, not only did not give people a sense of joy, but made people shudder.

"That's where the palace gate is."

Ao Xi pointed to the pair of 'eyes', and took the lead, followed by Li Zhen.

The two soon came to the palace gate, and the quaint and vicissitudes of the palace gate in front of them made Li Zhen speechless, how long has this been a silent place?

I'm afraid it will be counted in the thousands.

"Don't be too nervous, there is no danger for you and me to work together."

Seeing Li Zhen's nervous expression, Ao Xi comforted again.

Li Zhen retorted: "I'm nervous not because I'm afraid, but because I'm excited, because this is the first time in my life, and it may be the last time in my life." ”

Hearing this, Ao Lu shook his head speechlessly, then pinched his hands and said, "Next, I will open the palace gate, you are ready." ”

Li Zhen took out Jin Mingjing and the Storm Fan, waited for it, and nodded, "I'm ready." ”

Seeing this, Ao Xi lowered her head and began to chant the incantation, what she said was not human language, Li Zhen couldn't understand it, but she could feel a vicissitudes of life, as if an ancient call.

A moment later, the dull sound of opening the door sounded, knocking on the depths of Li Zhen's heart, making him even more nervous for a while. The palace door slowly opened, and a rotten breath rushed to the face, followed by a roar, deafening, like a violent storm, which made people shudder.

"Let's go!"

Ao Lu greeted, turned into a white light and flew towards the palace gate, Li Zhen couldn't fall behind, followed closely by his side, and two rays of light flew into the palace gate.

After Li Zhen followed Ao Xi and flew into the palace gate, what caught his eye was not the palace with long mountains, but a black ocean, with countless black shadows and thousands of them, rushing towards them.

"This is?!"

Li Zhen said in astonishment.

"Those are the water demons who have been eroded by the corpse qi of the dragon tomb, and they have completely lost their minds, and they can only kill madly, and they are also the guardians of this dragon tomb."

Ao Lu explained, and then took out the dragon-shaped jade pendant, and the treasure flashed, turning into a jade dragon that was more than a hundred feet long, roaring at the black shadow, majestic and wide-eyed.

"I can't deal with these water demons on my own, and I need your full help."

Ao Xi was not polite, and directly asked Li Zhen for help.

Li Zhen nodded, since he came, he must cooperate sincerely.

"Since I promised to help, I will definitely help in the future."

Ao Xi nodded gratefully, and then took the lead in attacking before the black tide-like water demon approached.

The types of water demons are miscellaneous, all of them are aquariums, there are countless shrimps, crabs, fish and mussels, and their strength is not too strong, and the strongest one is only at the level of a human immortal.

Ao Xi rode on the jade dragon, with an extra long sword in his hand, and drove the dragon into a horse to rush into the water demon group, and the corpses were all over the field, but the number of water demons was almost innumerable. Li Zhen naturally would not sit idly by, summoning the Gen Kun armor to protect himself, Jin Mingjing in his left hand, and the shocking fan in his right hand, the three magic weapons were both offensive and defensive, and then rushed into the demon group.

Where the golden light shone, countless water demons were killed instantly, the sea was rolling, the waves were urged, and the water demons were all swept to death.

Li Zhen and Ao Xi cooperated with each other, although they had never practiced before, but they were full of tacit understanding, and in just a moment, the corpses in the sea were all over the field, and the dark black sea water was dyed black and brown.

Although there are many water demons, the two of them are completely one-sided slaughter, but on the way, Ao Xi reminded Li Zhen, saying that she was defeated in the hands of these water demons when she came in before, and she withdrew in embarrassment, as for the reason, it is nothing more than that there are too many water demons, so many that they can't kill them at all.

At first, Li Zhen didn't have a deep understanding of this, but after the real fight, Li Zhen realized what it meant to be 'too many to kill'.

The water demon dies a lot, but rushes up even more!

As the battle continued, the number of reinforcements from the water demon was far greater than the two of them combined to kill, and the black pressure almost buried the two.

Li Zhen looked at the endless water demons and couldn't help but be surprised, how big is this water palace, and can it accommodate countless water demons?

"Let's fight like this, will it be over?!"

Li Zhen asked Ao Xi.

The long sword in Ao Lu's hand flew, the sword light was Huohuo, and the water demon was killed and injured everywhere he passed.

"I don't know what to do with these water demons, maybe I really have to kill them all."

As soon as Li Zhen heard this, his head suddenly became big, this is not a good way, I am afraid that the water demon will not kill it all, and he will be consumed to death first.

"You dragon clan are the emperor of the sea, and the water tribe in the sea all bow down to them, and completely suppress them in their bloodline, why are they not afraid of you at all?"

Li Zhen waved his fan in shock, and hundreds of water demons in front of him were immediately swept to death and turned into ashes.

"They live in the dragon tomb, they have been exposed to dragon qi and dragon power for many years, and they are corroded by corpse qi and are insane, and the dragon power in my body does not work for them at all."

Ao Xi explained, Li Zhen nodded silently, and said: "It's not a way to fight like this, you have to use some other means, otherwise it will be endless and harmful." ”

As soon as the words fell, Li Zhen took out the Five Emperor Ding.

"Since you are not afraid of death, then I will turn this area into a sea of fire, but I want to see if I can burn all of you water demons."

The fire of the five elements in the Five Emperors Ding gushed out, turning into a fire dragon roaring in the sea, and where it passed, the water demon turned to ashes.

Li Zhen did what he said, and everywhere he looked, all turned into a sea of fire of the five elements!

"Let's see if you're really endless!"
