The submarines of various countries, in front of an old dragon, are no match at all, and even other sea beasts are enough to pose a mortal threat to these submarines.

It is only a country of the level of the five hooligans that has enough foundation to install the defense capability of the cultivation side of these submarines, not just relying on the defense capability of its own alloy.

Submarines with general effects no longer dare to leave the port, and leaving the port is a dead end.

And even the nuclear submarines of the five rogue can only be cautious in the face of these sea beasts, because two fists are difficult to defeat four hands, and their opponents were each other before.

And can the number of submarines in the P5 be 1,000?

But now there are 10,000 times as many sea beasts as many as there are in the sea.

And with the revival of the aura, the number of these sea beasts will only continue to grow, and eventually occupy the entire sea world.

Unless all human beings embark on the path of cultivation, they can wrestle with these sea beasts and have enough strength to fight against these sea beasts.

Otherwise, sooner or later, these sea beasts will become a problem for their henchmen!

All countries are very aware of this, especially when they have a clear master and have the leadership of the Valley of Ten Thousand Demons, it is even more of a problem for human beings.

If Lu Xuan knew their judgment, he would also applaud.

Because their judgment was basically correct, in the previous life, the Valley of Ten Thousand Demons relied on the geographical advantages of the Australian continent, and then relied on the countless sea beasts in the sea, to form a confrontation with the human federal government entrenched on various continents, and the two sides fought for life and death for many years.

The figure of that old dragon was discovered from time to time by submarines of various countries and martial arts masters in the sea of various countries, and that old dragon did not care.

Those submarines were not vulnerable at all in front of that old dragon.

Even in the water, the speed of this old dragon swimming is extremely fast, and it can rush to the front of the submarine almost instantly, and the speed of the submarine cannot keep up with the speed of this old dragon at all.

Even if Huaxia's submarine had Lu Xuan's help and pasted it with a speed charm to enhance speed, it was much faster than many sea beasts, but in the face of this old dragon, it was still not enough.

Directly torn apart by a claw, even if a nuclear weapon is used from a distance, it is still difficult to hurt the old dragon who comes and goes like the wind.

What's more, the shock wave caused by the explosion of a nuclear bomb in the deep sea is enough to tear apart a nuclear submarine that is not far enough away.

In the face of an old dragon, all countries have no good methods, although nuclear bombs have indeed proved to be a threat to that old dragon, and even countries have had a lot of secret and powerful means over the years.

But that old dragon in the deep sea, even if he can find a trace by chance, it is only a glimpse.

But even so, after such a long period of exploration, the countries still have some information, the old dragon is healing, searching for some mutated herbs in the bottom of the sea.

But it is not only on land that natural and earthly treasures will be born, in fact, the deep-sea area, which occupies most of the earth's area, is the gathering place of real natural materials and earthly treasures.

Moreover, there is no such means of large-scale harvesting by humans, so there are many natural and earthly treasures, far better than those on land.

Even the bottom of the sea is famous for its mountains and rivers, which shine brightly under the amplification of aura.

There are even many masters among the human race, who are willing to risk their lives to go down to the deep sea to find those heavenly treasures, although the losses are great, but they are also quite rewarding.

All countries want to contain it, but there is no way, and the best way to deal with the cultivators is to use the cultivators.

Especially when this old dragon is still seriously injured, it should be an unprecedented opportunity, but they have no choice but to watch this old dragon become stronger and stronger.

And on Huaxia's side, Long and the others who got the news were also silent, and in the face of this terrifying existence, they had no way at all.

There is only Lu Xuan, and their only hope is in Lu Xuan.

I can only wait for Lu Xuan to get out!

Since Lu Xuan is prepared, then it may not be hopeless!

Time passed day by day, and Lu Xuan was out of the customs.

Lu Xuan looked at the blue sky and the white clouds, and there was a feeling that he was in a different world.

In previous lives, when I was practicing, I often had this feeling, and I would often retreat for decades, hundreds of years, and it was commonplace.

But now that he has only been in retreat for a few days, he has such a feeling, and it is really because his strength has increased too much in these few days.

Only he knew how amazing his strength had grown in the past few days.

Terrifying, powerful!

Now every move he makes, he will feel the suppression of heaven and earth, and the shackles of heaven and earth will suppress him, so that he has no way to make any breakthrough again.

His existence has exceeded the extent that Heaven and Earth allow the strength of living beings in this matter.

The sixfold pinnacle of the Divine Hidden Realm!

It was at this time that Lu Xuan's cultivation realm, with his many means, even in the face of the sevenfold powerhouse of the Divine Treasure Realm, he could break his wrists, there was nothing to fear.

At this time, he already had the strength to contend with that old dragon.

However, he was not in a hurry to find the old dragon, the old dragon was uncertain, looking for healing treasures everywhere to enhance his strength, and he would definitely find it in the end.

And Lu Xuan is also trying to enhance his chances of winning, in the face of such an old dragon, no matter how careful Lu Xuan is, it is not too much.

At this time, in the secret room of Yunxuan Mountain Villa, all kinds of heavenly and earthly treasures had already been piled up, and many ores that shimmered with divine light were also piled up in the secret room.

He wanted to refine a magic weapon that could deal with that old dragon, and the previous dragon slaying sword was too far away to deal with that old dragon.

It's just the level of a low-grade magic weapon, if you want to hurt the old dragon, even with the blessing of Lu Xuan's skill, it's very difficult!

After all, although the realm of that old dragon was suppressed, his physical body was extremely powerful.

The combat power is far better than that of the masters of the same realm, if it weren't for Lu Xuan, a terrifying existence like Lu Xuan, if it were a dragon and others, even if it was the same realm, it would not be the opponent of that old dragon at all, and even if he waited for three or five sieges, he would be beaten out of the dog's brain.

That old dragon is too strong, not only the strength of his own dragon bloodline, but also the original realm is very high, how can it be so easy to hurt him.

Even Lu Xuan had to reforge the Dragon Slayer Sword to slaughter that old dragon.

"Dragon Slayer Sword, I didn't expect it to be a word, it really wants to be used to slay the dragon!"

Lu Xuan said lightly, a flame rose in his hand, and the Dragon Slayer Sword gradually melted into a mass of metal liquid under the calcination of the flames.
