In the blink of an eye, another week has passed. Wu Dao calculated in his heart, it has been many days since Han Zongxian delivered the letter to her, but there is still no follow-up news, but she doesn't have to worry about the safety of that guy, after all, she is an old man, and she has a bunch of superior magic weapons from the fire realm, how can it be so easy to hang up.

On this day, the dragon ship was finally completed, and Wu Daoan also invited Daoyin Zhenren to finally lay some high-level defensive formations on it, which could be regarded as solving the security problem.

The advantage of this kind of Yuanying-level defensive formation is that as long as there is a continuous supply of energy from the spirit stone, the effect is as good as that of the Yuan-Infant stage master, and it is difficult for other Yuanying-level monks to break through.

In other words, this magic weapon is still useful in Wu Daoan's hands, because now that the spirit stones on the earth are extremely depleted, where can he afford such a bottomless pit that consumes spirit stones extremely much? That is, Wu Daoan, a monk who has made a windfall in the fire world, can afford to use it.

Okay, without further ado, Wu Daoan first threw the dragon boat into the storage bag (in fact, it was a storage bracelet to be precise), and then went to the side of Victoria Harbor, looked at the endless sea, took a deep breath, and disappeared with a dodge.

The sea seems to be calm inside, but in fact it is infinitely dangerous. Take water pressure as an example, if you dive ten meters, you will have to bear pressure equivalent to several times your own weight, and if you are exposed to water at a depth of 100 meters without armor, you are destined to be squeezed into jerky by the seawater. Therefore, if you want to dive, you must have a wetsuit. But there is also a limit to the wetsuit, a depth of a few hundred meters is the limit, if you want to go deeper. You need something like a sealed submarine.

The function of the dragon boat is similar to that of a small submarine, which can provide the necessary protection. Otherwise, although the foundation building monk has extraordinary physical fitness, he will not be able to withstand the water pressure at a depth of a thousand meters. Of course, it also depends on the cultivation. For example, a monk in the Transformation Stage has already understood a trace of the laws of heaven and earth, which is a sword mountain and a sea of fire that can be obtained anywhere. Wu Daoan is like this, he still has to obediently use tools.

The shape of the dragon ship is also very pleasing, it is a large round ball with a diameter of about 3 meters, and the surface is also gray, and it looks like a large torpedo from a distance. And it's a magic weapon. Naturally, there are some more awesome attributes. For example, the intricate and winding lines on the surface of the hull, which are Yuanying-level attack and defense formations, can be driven as long as there are enough spirit stones. In addition, the hull itself has damage reduction properties. Removes most of the attack damage. Protect the safety of the passengers as much as possible. Moreover, the maneuvering of the hull also depends on the true qi. It's not an engine or anything.

In short, Wu Daoan sat inside the big round ball like this, traveling quickly and quietly in the depths of the sea. Everywhere you go. Leaving only a slip of water swirling and curious fish.

Wu Daoan inferred the depth of the dive through the pressure gauge on the surface of the hull. 500 meters, 700 meters, 1,000 meters...... Two thousand meters, you can almost see the bottom of the sea here, and it is also the initial location of the undersea route map given by Han Zongxian, and then it is according to the map.

It is said that although Wu Daoan is sitting in a closed container, the reflectivity of the entire hull can be adjusted freely. When the reflectivity is set to zero, the hull is no different from glass, and she can see everything in the sea up close.

Similarly, the fish on the bottom of the sea were also deeply interested in this strange and strange "fish", and many of them surrounded the hull of the ship and "banged" into it. However, Wu Daoan didn't have to open the formation for this, because the hull itself fused the characteristics of diamond wood, and the hardness of this kind of wood was higher than that of diamond in the world, so this level of impact would not leave even a scratch, but these fish themselves were knocked into a mess and scattered.

Of course, there won't be just such a bunch of stupid fish on the bottom of the sea. It is true that the spiritual energy of heaven and earth has failed in modern times, but the order is from high to low. In layman's terms, it means that the aura on the ground dissipates quickly, while the aura hoarded on the bottom of the sea is relatively slow.

And according to convention, where the aura is strong, there is a higher proportion of beasts mutated into demon beasts. Demon beasts are to ordinary beasts, just like monks are to mortals, the stronger the aura, the faster the demon beasts are to cultivate.

In short, the strength of the undersea demon beasts should not be underestimated, so those Yuan Infant Stage Great Cultivators will not go to the bottom of the sea without anything. Correspondingly, these undersea monsters rarely go to the ground, and most of the time they inhabit the deep sea and live their own small lives.

But there are also some dishonest monsters, occasionally returning to the sea to show their heads, if they happen to be photographed by humans, it will become evidence of the xx sea monster. So those sea monster legends in those mortal worlds are really not groundless.

However, normally speaking, the order of the undersea monsters is very strong, and there are very few violations of the rules. In short, the deep sea is like an independent demon beast kingdom, and the human monks don't care about it, and they don't go to the ground themselves.

Of course, if Wu Daoan wants to go to the deep sea to recruit people, he will inevitably come into contact with this huge demon beast kingdom. As the diving distance deepened, she began to sense the breath of some demon beasts. Although the cultivation is not high, it is just a group of small shrimps with the strength of the Qi refining period, but it is indeed a demon beast.

Generally speaking, only primordial-level demon beasts have the same intelligence as humans, but the intelligence of those low-level demon beasts is far higher than that of ordinary beasts, and they will at least cautiously avoid the hidden dragon ship, rather than stupidly crashing into it.

Continuing to move forward, the foundation-level demon beasts also appeared, and this group of demon beasts not only knew how to avoid, but also gathered together to whisper, as if they were exchanging views. And some of the demon beasts left quietly, as if they were going to report the news.

Wu Daoan also heard a little about the demon beast world under the sea. In fact, these monsters have never been monolithic, and they are also divided into many independent small kingdoms. If you want to get to the Mariana Trench, you will always pass by several demon kingdoms. Because monsters love to stay in the deep sea, and the Mariana Trench is the deepest part of the ocean, where the aura is also the strongest, it is naturally also a gathering place for monsters.

Finally, a fish-headed beast-like demon beast appeared, stopped in front, and said something to the dragon boat. Although Wu Daoan couldn't understand it, he could still understand the meaning, it was nothing more than "Boy, you have passed by our territory, follow me to pay homage to the king!"

Wu Daoan still obediently followed the past, after all, theoretically speaking, the demon beasts in the sea rarely interact with the monks, so there is no grudge, and there is no reason to deliberately avoid it.

Wu Daoan drove the dragon boat to follow all the way, and came to a certain place on the bottom of the sea, and a bunch of buildings appeared out of thin air on the flat seabed, and the style of the building was a bit of the style of Shang and Zhou, which was probably copied.

At this moment, a huge tentacle octopus is waiting there. Why is it called a tentacle octopus? Because it looks very similar to an octopus, it is a hemispherical bare head, but there are a lot of tentacles underneath, more than a hundred, densely packed.

At this time, it also carefully looked at Wu Daoan and its ride, the sound rumbled like thunder, and at the same time, more than a hundred tentacles waved together, very majestic: "Hmph, this seat is the rumored wet and fierce big wet beast! Juniors don't come to kneel and worship!" (To be continued......)
