Thank you to the book friend Ziyan~.

After bidding farewell to Second Brother Yi, Lin Tuo did not immediately turn around and go into the water, but stood in place, looking at the direction of the black fog that engulfed Second Brother Yi.

Continuing into the distance, there is the Valley of the Hidden Sun......

Sister Yue had better be fine, otherwise, when I come back next time, I will definitely turn you upside down and bleed!

Gritting his teeth and swearing a heavy oath, Lin Tuo put the sealed boat more than one person high into the dark river.

The thousand-mile boat driven by the talisman can be well suspended in the water, and the current can be moved forward with spiritual power, some like small submarines, and like underwater motorcycles.

Launching the boat, entering the boat, closing the hatch, having seats, a narrow lookout window, a lever and buttons, everything is similar to that in a turtle.

Anyway, in another world, there is also a clan, and it is not the first time that this mechanism has been seen, and after a few fiddling sessions, Lin Tuo mastered the basic tricks, and sank the boat into the water safely.

The cabin is very small, and it is said that it can support a person's breathing for ten minutes to a quarter of an hour, and then the oxygen will run out, and before that, it must be marked along the map to reach the ventilation port on the fork of the water vein.

For others, this process is indeed dangerous, because it is very likely that if you misidentify the road once, you will never have a chance to turn back, but for Lin Tuo, it is really not difficult, because ...... He doesn't need to surface for ventilation, as long as the cave is embodied in the water, just sail the boat into the cave to ventilate.

The gate of the cave was transformed into a submarine-like double-layer isolation structure by him, opening the outer door, driving the boat in, closing the outer door, opening the inner door, releasing water, ventilating, and then closing the inner door, opening the outer door, and sailing out.

This is what he told Second Brother Yi, the method of underwater ventilation......

So ventilation is not a problem at all, the important thing is to escape, although in this waterway, there is no black fog, white fog and any disturbances such as Ding Array, Lin Tuo is very clear, in the Hidden Sun Valley, there are quite a lot of aquariums, fish people, shrimp people, crab people, loach people...... There's everything.

If they reach out in this direction and realize that they are going to escape from the waterway, the time will be ...... It depends on the speed of the boat, whether they swim faster or not!

Scanned the map given by Second Brother Yi into the eyes of the bronze treasure, directly inserted the rune yuan into the drive slot, and urged with all his might, Lin Tuo operated the thousand-mile boat, and disappeared into the "rumbling" sound of the underground dark river at the fastest speed.

Velocity...... It's pretty fast!

Maybe when I was making a boat, I was thinking about saving my life at a critical moment, and this boat was completely different from the slow swallowing of the turtle at the beginning.

There is no discharge of propellers or the like, and the current of the water passing through the boat will automatically be bound by an inexplicable force and gush backwards, bringing a steady and rapid forward force to the boat.

If it weren't for the tight time and heavy tasks, Lin Tuo really wanted to stop, disassemble the boat, and study what the engine inside was constructed in.

The speed of the boat is fast, moving forward in the twists and turns of the waterway, after the calculation of the treasure eye, the appearance of more than 60 kilometers per hour, this is the limit, the shape of the boat itself is not very in line with the streamline, running to this speed, the boat body will begin to violently bump and und, accompanied by a large number of bubbles agitated and generated, taking away a lot of energy from the engine.

The speed of the world's mainstream submarines in the last time was roughly in this area, 33 knots, around 61 kilometers per hour.

The boat is light, but it is quite powerful, and if it were to be modified and the cabin hull was redesigned according to hydrodynamics, it would not be impossible to reach the submarine's limit of 42 knots at a speed of 78 kilometers per hour.

It's fast, but it's still a big deal compared to the fish in the water!

Sixty kilometers per hour, that is, the ordinary swimming speed of fish, the last world ocean swimming champion sailfish, can swim 120 kilometers per hour, about 66 knots of high speed.

This strange world is so unscientific, even the swimming speed of the sailfish is probably not counted at all, how dare Lin Tuo not do his best?

Resist the bumpy vibration of being a massage chair, control the mechanism of the thousand-mile ship, and gallop!

There was no mist in the water, and the bronze treasure eye was running at full strength, clearly projecting the situation within forty meters around it in his eyes, comparing it with the map given by Second Brother Yi one by one, beware of making mistakes in the direction.

After walking forward for more than a quarter of an hour, in the bronze treasure mirror, there were two or three messages of essence blood positioning, from the frequency and density of positioning, Lin Tuo knew that the people in the Hidden Sun Valley had not yet realized that they had left along the waterway and let out a long breath......

But soon, he realized that his breath came out a little earlier.

Why? Because in the process, he drove the boat and gradually got out of the confines of the formation.

Obviously, the peak array of this hidden sun valley is somewhat similar to the town stone in the original Qianshan Village, which can deter the ominous and disperse the demons and ghosts, so in the water around the Qianshan Village, including the thousands of meters deep pool when entering, there are not many fish and shrimp to survive, and even if there are, they are all small fish and shrimp.

But once you leave this range, the heavens and the earth suddenly turn, and the whole weather is very different from before!

The boat moving forward ...... "boom boom", with noise, rolling bubbles, traveling in the deep water, like driving a big truck in the middle of the night, galloping on the street, the sound came far and wide!

"Boom!boom!boom!" It didn't take long for Lin Tuo to find that from the top and bottom of the boat, the glowing fallen leaves slowly floated out, like a fan, and turned horizontally to approach the boat.

In the dark underwater world, it is very gorgeous, like standing under the clear sky in the autumn light, looking up at the fallen leaves falling in the wind on the top of the trees.

But...... When the glowing leaves approached, Lin Tuocai suddenly woke up, where is this Nima What kind of leaves? It is clearly a small fish the size of a palm, and the graceful rotation like a ballet is not really spinning, but to cut people!

These fish, though small in size but extremely hard, came to the boat and began to take their glowing fins and spin and cut the boat.

"Rub, rub, rub!" There was a deep scar in a turn, and the sound of slashing and axes was only a few places at first, but soon more and more, although Lin Tuo immediately inserted the rune into the card slot of the protective cover, opening the basic protection of the boat.

But it can't support it for long at all, one rune yuan provides 1,000 points of protection, this small fish can knock out dozens of points in one turn, and at the same time, dozens of fish do it, and the rune yuan is not ...... in an instant

Moreover, this glowing deciduous fish still has a tendency to gather more and more, once the number increases, the speed of Lin Tuo's replenishment is not as fast as it is consumed!

Moreover, even if he is worth tens of millions, he can't withstand such crazy spikes in consumption! But what can he do without consumption? If he allows the boat to be cut into pieces, then he should be the one who should be cut, right? This is really a thousand cuts!

It's too ferocious! It's too strong! Can't help it! Thinking about the consequences, Lin Tuo sweated profusely......
