Lin Tuo didn't go into the water in the end, but still thought about it in front of him, and pulled back

It took more than half an hour to come, and this time, it took more than half an hour to finally come to the collapsed hole

It was completely blocked by the collapsed rocks, the air was blocked, and at the mouth of the hole, there was still a smell of gunsmoke that did not dissipate

Standing quietly in the place of collapse, listening intently, there was not the slightest unusual sound coming

However, it would be a mistake to believe that this means that things are settled and the enemy has retreated

The cavity of the tunnel is a few hundred meters away, enough to block out all sounds, whether it is the sound of people talking or the sound of digging and clearing

Not to mention a few hundred meters, even if it is ten meters, it is enough

It can't be heard by human ears, even if Lin Tuo has already stepped into the bottleneck

I can't hear it, but I can see it with bronze eyes

With all its might, all the sounds within eighty meters can be presented in the eyes of the bronze treasure in great detail

As for eighty meters away, there is also a way

In ancient times, there was the art of listening to urns to prevent the enemy from digging tunnels, and in modern times, there are stethoscopes and the like

Amplifying the sound resonance in the soil and introducing it into the air from another medium is too simple for Lin Tuo

I won't say much about the detailed situation, but after a little arrangement, Lin Tuo's bronze treasure eyes clearly showed the sound wave signal in the distance of the hole

According to the analysis of the bronze treasure eye, there is a sound of rock collision inside, which should be mining, or it may be an aftershock;

Someone speaks with a higher frequency, probably because of a woman, maybe because of anger, and of course, it is also possible that it is an angry woman......

Just as Lin Tuo had predicted, the enemy did not retreat, but was outside, cursing and cursing while digging the way

is so stubborn and entangled, the woman and the bandit leader Zhongli outside must not have one leg, but many legs

Lin Tuo's heart is the same as Spiegel, waiting is not good, although the excavation is slow, since the woman is willing to work hard, there will always be a day when the excavation will be thorough

Even if she doesn't dig hard, very, very slowly, the cavern under the ground can heal itself, and in three days at most, the tunnel will inevitably return to its original state, and by that time......

Since they are all planning to move away from the falling rocks, they have the patience to wait for three days, and the women outside must have them

So Lin Tuo had two more choices

One is to follow the road and return, continue to move forward, keep moving forward, and do not believe that you can not find the exit;

The second is to find a random place and start digging a fork in the road with digging machines, explosives, and your own manpower

Since there is no way out, why don't you make a way out?

This is not an easy task, the cave is vast, although the holes are criss-crossed, dense as the meridians of the human body, compared to the soil, after all, it is a small part

It is possible that the excavated cave grazed the edge of other holes and extended all the way, but it was not accurate, and there was no way out

Although there are various scanning methods for the Bronze Treasure Eye, and even X-ray, CT, MRI and other fluoroscopy methods, it is not possible to penetrate the land with real perspective

Not only can't the perspective be done, although along the way, a small map has also been drawn, but the small map attached to Lin Tuo's naked eyes and senses is inaccurate and uncountable

If you want to use the means of calculation-assisted correction to accurately and accurately export the composition, and clarify your current position, the relative position of the rift you saw at the beginning, and the relative position of each hole outlined by the rift observation, then you can't scan the field of view

If you can't scan, you can't run so fast and grope in the dark......

Whichever path you choose, though, one thing is certain

While thinking about it, ......Lin Tuo had already withdrawn a few kilometers back

When I felt that the distance was almost the same, the explosive devices that had been predetermined exploded one by one

From afar, it erupted all the way, until it exploded to Lin Tuo's feet

The tunnel several kilometers long collapsed completely

He didn't directly feel the impact of the explosion, but drilled into the cave, and when the explosion passed, Lin Tuo easily and happily drilled out of the cave, continued to walk, and swept towards the endless front of the hole Buddha

In fact, there is another way to go out more easily and happily, which is to dig a small hole in the wall of the hole, just like Zhi Duoduo did at the beginning

Dig an independent space that doesn't want to dry with the hole, and then block the exit, the cat is inside, and wait until the Yudan period to dig all the way, and after passing by, he will come out of it and run out along the road dug out of the Yudan

By the way, there are still a few grenades in the back, blowing up the cave wall, so that the Dan period can also taste the taste of being trapped, killing two birds with one stone, and it is very happy

Merely......

The hole here is weird, and since there is water in front of the hole, it is obviously not the endless snake path of the Buddha in Dragon Ball

If you look ahead, you might find something

This passage is very strange, and it is even very likely that it was not born and grown

Legend has it that the earth is the incarnation of the ancient gods, and the underground channels are the meridians and bloodlines of the ancient gods

That being the case, when will there be a meridian or blood vein in your body, which does not intersect with other people, and is a lonely one, and it wears down from the epidermis

It must not be a meridian or blood vein, but an ear canal, a mouth or a urethral opening, a chrysanthemum......

In short, this is not an ordinary thing

After taking care of the back road, Lin Tuo had no worries, walked forward, and soon came to the water's edge again

The hole that is several kilometers long has collapsed, and even if it is in the Dan period, even if it is in the Dan period, and other people are called to come during the Dan period, it cannot be cleaned up without two or three days of effort

Even if they really clean it up, or after three days, the cave wall heals on its own, and they blow up another section of the road, won't there be another three days?

As for the moment, even if you bomb more, it won't be of much use, because by the time the enemy chases here, because of the time relationship, the place that has collapsed should be almost long

At the water's edge, Lin Tuo took out the underwater equipment

It is a water cushion with the best attributes, shiny and shiny, showing the curves

Not only do they have a variety of attributes, but they also include exclusive properties such as speeding up swimming and increasing the duration of underwater breathing

At the same time, the front chest and back of the water are equipped with a metal-phase wooden vest like a life jacket like a Buddha made of chestnut oranges

On the vest, there are two water-driving arrays engraved on the front and back, as long as the rune is inserted, the water-driving array will be activated

One split a large bubble at Lin Tuo's head, allowing him to exchange breaths;

The other drives the current, creating a thrust that pushes him forward

If you want to swim fast, then you can swim out with fins and flippers with water repellent arrays on your hands and feet, and the degree of 100 kilometers per hour is 100 kilometers per hour

Lin Tuo quietly dived into the dark water, and there were not even any bubbles leaking out

The next step is to move forward, keep going, keep moving forward......

Just like the land route, a single road is long, twisting and turning, turning and turning

Although it is said that the speed of running under the water is not as good as that of land, but with the help of many means, it is not inferior in the slightest

As a result, Lin Tuo's fierce son went down, for four hours, two hours, and still there was no end in sight

The two waterways that come to the hour, running for a full 500 miles, are still oblique downward, according to the estimation of the bronze treasure eye, the dive can be 100 miles, the specific location is not very clear

One hundred miles is fifty kilometers, fifty thousand meters

The pressure of one atmosphere at a depth of ten meters, that is, 5,000 atmospheres, is five times greater than the pressure in the Mariana Trench, the deepest part of the ocean

This kind of depth, not to mention a mere congenital top, even if it is the Dan period and the Yuan Infant stage, I am afraid it will be crushed into a ball of meat sauce

However, the pressure of the water was the same as when I first dived, and I couldn't feel the biting cold that should have been in the deep water

If it weren't for this, Lin Tuo would have turned around and gone back earlier, how could he have persevered until now?

Moreover, I have long felt that this hole is strange and abnormal in the waterway, which has confirmed this speculation

So at this moment, Lin Tuo was very interested to see what was in the depths of the water

Prompted the degree, perseverance to go downstream

After swimming for another two hours, the Bronze Eye estimated that it had gone down for at least another fifty kilometers, and it was still nowhere to be seen, but the water was slowly getting hotter

Eventually, things are starting to change......

Normally, the water should be slowly getting colder, because the specific heat of the water is greater, and the sunlight cannot shine in at all

If you want to get hot, there is only one situation, and there is geothermal activity connected here......

The water warmed up continuously and slowly, at 50 kilometers, it was about 10 degrees, it was dark and cold, at 60 kilometers, it rose by about 5 degrees, and at 70 kilometers, it rose by another 5 degrees, which is considered to be a relatively suitable temperature

After nearly 100 kilometers of going deep into the waterway, the temperature has risen to thirty or forty degrees, and it is starting to be a little hot, but I still hold on

The old man took a bath, and he was soaked in the hot water as high as fifty or sixty degrees, which was really nothing

Although the temperature is not high, the continuous and steady increase in temperature is meaningful

Waiting ahead, there may be a volcanic lava field, so the heat can be radiated into this underground waterway

If this is the case, there is nothing to see ahead, although in this world, the extremely harsh environment often means great gains such as natural materials and earth treasures

However, Lin Tuo is self-aware, and with his current small power, he is far from the point of polar exploration

Not to mention entering the volcanic lava, even if the geothermal heat is slightly active, the temperature of the water in the vicinity will rise by thirty or fifty degrees, which is enough to absorb it for a while

Now, I'm more than 100 kilometers underwater

Even if the temperature does not rise, the mechanism that keeps the water pressure from increasing suddenly fails, and it is also unbearable for itself

That's it, before the strength arrives, it's better to be honest, don't be affected by the lovesickness curse, frizz and lose your life

Thinking of this, Lin Tuo decisively turned back

However, just after two strokes, a voice suddenly sounded: "Don't, don't go......"
