If you want to go into the water and dive for so long, Hao Dong has no habit of masochism, so naturally he still has to make some preparations.

First of all, let's make sure it's really clean underwater.

Luo Buqin nodded again and again: "I've watched it several times, but there's nothing." ”

Hao Dong was still a little worried: "But there were two who escaped at that time, how could only one come?" ”

This Luo Buqin didn't know: "Maybe one was injured and died?" ”

Obviously, this is not a question that can be easily discussed, and Hao Dong quickly gave up on getting to the bottom of the matter and turned to the method of carrying air.

Underwater is nothing more than not being able to breathe, and the most important part of diving equipment is the oxygen pump. Under their current conditions, pure oxygen is impossible, but it is still possible to get some air bags to carry with them.

Hao Dong's own things have basically been lost, and all he left for him before Qi Jue left him was food and a first-aid kit, so now he can only search for Luo Buqin.

Luo Buqin has a lot of things in his bag, and after removing the food, there is still half a backpack of supplies, and it is not difficult to turn over a few sealed bags from it.

They also don't have inflatable tools, so they can only hold the bag as big as possible and tie it tightly after the mouth of the bag, and how much air can be filled in it.

It takes about five minutes to go underwater, and you can hold on for one minute according to full breathing, and considering that the ventilation in the water cannot be so sufficient, Hao Dong used up almost all the sealed bags, and tied a total of twelve small bags.

The clothes on his own body were still those of the expedition team, and his coat and pants were still very strong, except for the shirt that had been scratched when he was dragged by Shirahoshi before.

He took off his coat and trousers, put them together in a large sealed bag, and stuffed them into his bag. In this way, you can wear it directly when you go ashore for a while, and you don't need to find a way to dry it.

The belt on this body is very special, there are many buckles on it, and those small air pockets can be hung one by one. After you can't hold it back in the water, you can take one down and use it, and it should be no problem to hold on for five or six minutes.

Luo Buqin looked at this circle of small pockets and felt Coke, glanced at it, and laughed "poof"; Take another look and laugh twice.

Hao Dong glared at him: "What are you doing?!" ”

Luo Buqin shook his head again and again, and his curly hair trembled: "No, nothing." Poof—"

Hao Dong didn't bother to bother with him, his backpack threw on his shoulders, and pushed Luo Buqin: "You lead the way, let's go." ”

Luo Buqin obviously hadn't laughed enough, but wasting all his time on this was obviously a brainless thing, so he still took a deep breath to restrain his laughter, carried his things, and turned over and took the lead in the water.

Hao Dong finally looked around meaninglessly, took a deep breath, and followed into the water.

The temperature of the underground river is quite low, and every time I go to the water before, there are accidents, although it is cold, but because of the adrenaline rush at the same time, the body's perception decreases, and it is not difficult to endure.

At this time, when he went into the water, all the indicators of his body were within the normal range, and he had not done any kind of warm-up exercise before entering the water, and the only little stress reaction he had when he killed the snake man had caused the rise in body temperature had already fallen, and Hao Dong couldn't control it as soon as he got into the water.

In fact, it is a very bad habit not to do warm-up exercises before entering the water, especially this kind of cold and biting water, which is very easy to cramp when you go down.

Hao Dong was suffering a little now, and after being surrounded by this cold and heavy water, his left calf muscles began to jump uncontrollably.

Luo Buqin was swimming unhurriedly not far in front of him, and according to Hao Dong's normal speed, he should be able to keep up, but the sudden situation on his leg slowed him down a bit, and soon a distance opened between the two.

Originally, this distance was nothing, Hao Dong's calf condition did not develop to a more serious extent, he tried to control the condition of his muscles while swimming, and consciously stretched, so he slowly adapted to it and could chase forward.

As a result, it was as if he really had an accident physique, and the bottom of the water, which was originally calm and waveless, suddenly became turbulent.

There were two people and one pet in their group, Bai Xing swam fast and had already rushed to the front, Luo Buqin was second, Hao Dong was the last one, and the position where the turbulent water appeared was behind them.

Hao Dong was the first to feel the change in the flow of water, and at the same time, a sixth sense suddenly erupted in the face of danger.

At that time, he had just used up the third air bag, and it was estimated that he would have to swim for another three or four minutes, but the water behind him suddenly surged, and in an instant it formed a very good thrust for him.

But Hao Dong didn't feel happy because he could save effort at this time, but the alarm bell was loud, and he felt that something troublesome was chasing in behind him.

The waterway itself was not very wide, and the walls were so potholed that it seemed to have been dug by the snake man with his own hands.

It would be more difficult to turn around in such a place, and before Hao Dong could completely turn around to see what was behind him, he felt that something had been chased.

As the thing approached, it grabbed the neck of one of Hao Dong's feet, and the exposed skin was suddenly entangled with a slippery and cold feeling.

And the thing had to be inched in, and then the other hand grabbed it and used its strength.

Hao Dong was in pain, realizing that the thing seemed to mean to break his leg off.

He was in a hurry, his body subconsciously curled up, and his right hand pulled out the machete inserted in the side of the backpack, and slashed at the black claw that grabbed his leg with the faint light of the waterproof flashlight.

By this time, he could see clearly that it was the other snake man he had been worried about why he hadn't appeared.

The skin of this thing is very hard, and Hao Dong tried his best to cut it without even a mark, but it only made the thing frightened, and the strength in his hand loosened slightly.

Then this time it loosened, and Hao Dong immediately retracted his legs. didn't bother to look at the bruises on his legs, so he immediately showed Liu Lan.

This snake man is not a human after all, and his IQ is not very high, and when he found that Hao Dong's knife actually had little effect on it, he immediately bared his teeth and pounced on it twice.

This time, Hao Dong's knife was raised again, and it was not afraid at all, and even dared to reach out and grab it. It seems that he wants to grab the white blade empty-handed, and directly make Hao Dong defenseless.

Hao Dong's knife was aimed in the direction of its eyes, it grabbed it with its left hand, and its body did not pause, pushing the knife and continuing to pounce forward; The right hand stretched out and grabbed the heart of Hao Dong's chest.

Hao Dong's right hand was temporarily restrained by it, and the shooting port of Liulan in his left hand was aimed at the head of the thing, and his mind was racing:

Or he'd have to find a way to make the thing open its mouth so that the potion in the stream could work; Otherwise, he'd just shoot the thing in the eye with a small arrow.

Or the third way, if you get the potion on the small arrow, then one arrow will solve the problem.

At this time, he regretted it a little, he had long known that the arrows could quench poison, but he didn't even think to soak these arrows in potion earlier!

Right now, they are in the water, and it is very easy to shoot the potion directly into a situation where it will hurt the enemy by one thousand and damage eight hundred, and this moment of lightning and flint does not allow Hao Dong to think too much, before the snake man's hand was inserted into his chest, the small arrow in the liulan dragged the long universal silk with its tail and sank into the snake man's right eye socket.

The dark, thick, and fishy blood water came out of the wound caused by the small arrow after a while, and the snake man was also startled by Hao Dong's hand, and it took more than half a second to react.

At that time, Hao Dong had already quickly slid forward for a while, and at the same time began to feel a little stuffy pain in his chest.

The energy of the small arrow is not small, and this arrow directly pierced the brain on the right side of the snake man. If it were an ordinary human, this would be enough to kill you.

However, this thing is a monster, and although the right eye, which has been cracked under the pressure of the water, has begun to flow out of the eye socket, its own mobility does not seem to be hindered at all, but because of the pain, it is provoked a strong reaction.

The worst that Hao Dong feared happened.

It had a snake tail and was obviously more adapted to moving in the water than Hao Dong.

As soon as the crazy snake man exerted his left hand, the machete that had always been of great help to Hao Dong came into his hand, and with another force, the knife was directly pinched and deformed.

The snake man threw the thing away, his tail swung sharply, and the water that had pushed Hao Dong forward before reappeared, and the speed of the snake man in the water was like a discharged gun, and he rushed straight towards Hao Dong.

Obviously, this thing doesn't plan to slow down anymore, and wants to solve it quickly.

Although Hao Dong has retreated a distance, under the explosive power of this thing, the distance he retreated before is obviously not enough. Almost in the blink of an eye, the snake man was bullied again.

This time, it bared its teeth and claws, as if it was planning to grab Hao Dong and bite his throat directly.

The face of this thing was covered with a strange substance mixed with thick black blood and a little yellow, excessively viscous and fishy brain pulp flowing out of the brain, wrapped in saliva with the same color of yellow and black and stenched saliva in its mouth, and bit it off at Hao Dong.

Hao Dong's lungs were already swelling and painful when he was holding his breath, and there was some swelling in front of him, and he didn't have time to think about it this time, so he directly pushed Liu Lan's launch port into the mouth of this thing.

In addition to the original anesthetic, Liulan's potion also contained the potassium cyanide that had been added before. The potion squirted directly into the snake man's throat, along with a second small arrow.

The snake man was already too close at this time, and he probably didn't expect Hao Dong to resist at this point, but he was slightly blocked by the arrow.

Hao Dong immediately retreated again, but unfortunately the wound deep in his throat was obviously not as bad as the one on his eyes, and the snake man only paused slightly, and the claws that stayed in the air still fell.

Hao Dong withdrew less than a meter away, and this time he directly grabbed the small pocket in his waist.

The cyanide quickly took effect in the snake man's body, and in an instant the thing struggled even more violently. Hao Dong didn't care about anything else at this time, he turned around and ran, holding back his chest and feeling like it was about to explode.

This ran until he rushed out a long way, and the snake man would definitely not be able to catch up with Hao Dong slowed down slightly, and then immediately grabbed the small pocket in his waist in a hurry, intending to continue breathing.

He felt like he was about to faint, and he just wanted to save himself before the last bit of consciousness was gone.

However, at this time, he realized that the small pocket in his waist was actually lost and broken, and it was tossed all over in that time just now!

Before Hao Dong finally lost consciousness, the thought that flashed through his mind was why he wanted to drive Qi Jue away.

If Xiao Qi Ye was still there, he would never leave himself alone and run so fast;

If Xiao Qi Ye is still there, he will find the danger earlier than himself when he encounters this kind of monster, and he will definitely stand in front of him;

If Xiao Qi Ye is still there and finds that he has lost those air bags, there must be other ways to let him catch his breath, and he may not even use to dive into this water at all, because Xiao Qi Ye can find a way to blast away the pile of rocks above......

Wait, this kind of drowning scene seems to be really familiar, at that time I was about to drown, and I couldn't touch the water at all, at that time, someone took a breath for himself, so that he could hold on.

No...... In fact, he still floated to the surface in time?

He remembered that there were two people who carried him to escape, and it was also a very large underground river, and the current was so strong that he was almost crushed to death by the waves countless times, and countless times he was fished or thrown onto the surface of the water at the last moment, so that he could breathe a sigh of relief.

He remembered that there was a huge fish that leapt out of the water and flew in his direction, and when it came close to him, it suddenly turned into a hairy face, and its open mouth was foul-smelling and disgusting.

Then Hao Dong really retched, and at the same time rolled over and propped himself up on the ground.

Thanks to Bai Xing's artificial respiration, this stimulation was so strong, Hao Dong felt as if he had forced the experience of the past six months out of the depths of his memory.
