The next morning, the sky and the earth were dark.
"Booming~~~" The thunder roared, and scattered raindrops fell faintly.
"Qingshan, look at the weather, there will be heavy rain. Don't go to the mountains to practice hard this morning." Mother Yuan Lan put on a big cotton jacket and walked out of the back room.
"Mother, it's okay, this little rain is nothing. Well, I'll go up the mountain first." Teng Qingshan grabbed the iron gun and walked out.
"Come back early for breakfast." Mother Yuan Lan shouted.
"Understood." Out of the gate, Teng Qingshan quickly left Tengjiazhuang and went up to Dayan Mountain.
…
"Hoo!" "Hoo!"
Teng Qingshan turned into a phantom, walking through the mountains and forests. When leaving Tengjiazhuang, there were only sporadic raindrops falling from the sky, but after Teng Qingshan entered Dayan Mountain, with the sound of thunder, the rain suddenly became violent, and there was a vast expanse of water between the sky and the earth.
In an instant, Teng Qingshan was poured into a drenched chicken, and his whole body was drenched.
"It's really unlucky." Teng Qingshan frowned.
It's a trivial matter that the body is soaked in the rain. And when he came out in the morning, he had nothing in his pockets, Teng Qingshan was not afraid of the rain, but... now that it was raining, the plan to sneak into Bihantan would be a bit troublesome.
"No matter what, if you decide to lurk in Bihantan today, that's today."
Teng Qingshan walked swiftly, and he came to Shuangtou Mountain in a while, this mountain wall was like a smooth path for him, the spear that was disassembled in two was placed behind his back, Teng Qingshan used both hands and feet, and he reached the top of the mountain in a while. Then he jumped down directly from the top of the mountain, slapping the rocks along the way with his hands from time to time to slow down his speed.
"It freezes really fast." Teng Qingshan landed halfway up the mountain, on the open space two feet away beside Bihantan, looking at Bihantan with a wry smile.
I saw that the surface of Bihantan had already condensed into a thick layer of solid ice.
"This ice layer must be at least 30 centimeters thick. How long will it be?" Teng Qingshan was helpless. The water in the Bihantan is very special. No freezing. And whenever it rains, when the rainwater comes into contact with the water of the Bihan Lake.
The rainwater will freeze quickly!
It has only rained for a while, and the ice is one foot and two inches thick.
But Teng Qingshan also knew that even if it rained continuously, the ice would be two feet thick at most.
"My clothes are all wet, so I don't need to take off my clothes when I go to the deep pool today." Teng Qingshan threw the package of the iron gun on his back aside, randomly picked up a big stone from one side, and jumped away. Standing up, the whole person landed firmly on the solid ice. Stepping on the solid ice, Teng Qingshan could still feel the chill.
suddenly-
Teng Qingshan stamped his feet violently!
"boom!"
As if the sky and the earth were collapsing, the one-foot-two-inch-thick solid ice was suddenly cracked and collapsed, collapsing and flying around, and many shattered ice blocks hit the nearby mountain wall and exploded into pieces pink.
"I don't believe it, this time I still can't reach the bottom." Teng Qingshan rushed into the Bihantan with a huge stone weighing more than 100 jins.
The low temperature is enough to freeze ordinary people to death, but Teng Qingshan easily resisted it wearing only a single coat.
"Wow~~"
The continuous sinking caused the flow of pool water.
"It stands to reason that the sky is bright now, but it is raining heavily today, the sky is gloomy and dark, and the visibility in the water is very low. But... my eyesight is much better now than it was a month ago, and I can see farther underwater." As long as there is a trace With the help of light, Teng Qingshan can see his surroundings clearly.
fall!
Keep falling!
Twenty feet!
Forty feet!
Sixty feet!
…
"I have been exposed to this extremely cold low temperature many times, but I still feel too cold and uncomfortable." Teng Qingshan carefully watched the objects on the side walls around the cold pool. There were some objects on the side walls deep in the cold pool. reference. Teng Qingshan can completely rely on the reference object to distinguish the approximate distance of his descent.
"It should have crossed the foot of the mountain and reached the bottom of the mountain!" Teng Qingshan estimated the depth.
Last time, Teng Qingshan couldn't bear it long after reaching such a depth, and used his inner strength to protect his body. But this time, Teng Qingshan only relied on his muscles to resist.
Keep falling!
"It's really deep. This is underground. I've already sunk three hundred meters." Teng Qingshan felt extremely cold, and at the same time—
"Kaka~~"
The 100-jin stone in his hand started to crack.
Cold enough to split stones! What a low temperature this is.
"It's so cold." Teng Qingshan had never felt such extreme cold in his previous life, as if his strong muscles and membranes had no hindrance, the extreme cold directly stimulated the bones, and even faintly stimulated the internal organs, cold, the whole body was icy cold , "You must use your inner strength!"
The ferocious internal energy is running crazily all over the body to resist the low temperature.
"It's much better." Teng Qingshan looked carefully at the pool below, because it was too deep, even with Teng Qingshan's astonishing eyesight, he could barely see three or four meters around.
"Um?"
Teng Qingshan looked down carefully, "Is it the end?" There was a faint purple halo below, and this very faint purple halo allowed Teng Qingshan to see the distance of seven or eight feet clearly at once, and with the approaching , Teng Qingshan noticed that the temperature started to pick up.
Yes, the original extreme low temperature actually started to rise again.
But when Teng Qingshan's feet fell, he was finally pleasantly surprised—this is the bottom of Bihantan.
"Huh? The bottom of this cold pool is actually hot? And there is a purple halo, which is strange." Teng Qingshan was very surprised. He finally knew why the water near the bottom of the pool became warmer. That is the reason for the strange ore at the bottom of the pool.
Look carefully around the bottom of the pool.
Because of the visible range, there is a distance of seven or eight zhang, so Teng Qingshan quickly discerned the situation at the bottom of the pool.
"The bottom of the Bihantan is about ten feet wide, and the length... is more than twenty feet." Teng Qingshan looked at the left side carefully, because only the cold pool wall on the left side of the bottom is two or three feet long. A wide channel, "It turns out that the water in the cold pool flows from this channel."
Teng Qingshan also noticed that the closer to the direction of the passage, the colder the pool water becomes.
There is no living thing, no plant, only one thing at the bottom of the pool—a strange hot ore. There are many such ores scattered on the surface of the bottom of the pool.
"Yeah." Teng Qingshan picked up a piece. This kind of ore itself has a very faint purple halo. Under the dark conditions at the bottom of the cold pool, this purple halo can be seen. It is estimated that in the daytime, the outside world may not be able to see clearly. .
"Under such extremely cold conditions, it can generate heat instead. And the heat is still very high. It should not be an ordinary ore. Take it back and let Dad identify it." Teng Qingshan picked up two fist-sized ores and put them inside the chest of the clothes In the big pocket, the pocket can only hold two pieces of ore.
Immediately, Teng Qingshan turned to the left, and the cold pool water channel approached.
"Huh, it's really cold. It's pitch black inside, and the visibility is even lower. I don't know what's there." Teng Qingshan watched the passage carefully, but there was no such strange ore deep in the underwater passage, so it was pitch black. , Teng Qingshan could barely see a distance of two feet, and had no idea what was in the depths of this mysterious underwater passage.
But Teng Qingshan felt a crisis in his heart...
"If something goes wrong, there must be a demon! With the low temperature and water pressure, my body's ability to withstand it is almost reaching the limit. I also reached the bottom of the pool today, and the goal has been achieved. I'd better go back and let Dad see the ore. I will wait until I have a chance in the future. Enter this underwater channel." Teng Qingshan immediately decided to go back outside.
In the underwater channel, Teng Qingshan's eyesight cannot reach.
A pair of broken golden pupils the size of a fist stared faintly at Teng Qingshan. It was tens of feet away from Teng Qingshan, but it was obvious that this underwater monster could see Teng Qingshan clearly in such a dark situation.
Quietly, the underwater monster began to approach the entrance of the cold pool underwater passage, and the underwater monster moved without making a sound.
Standing at the bottom of the pool, Teng Qingshan threw the cracked boulder, and his whole body floated upwards.
at this time-
"laugh-"
Discovering that the underwater monster Teng Qingshan was about to leave, his speed increased sharply, like a flash of lightning, he rushed out of the underwater passage all at once.
"what!"
Teng Qingshan, who was floating up, of course noticed such a violent movement. He turned his head suddenly, and seeing this, his heart convulsed violently, and his scalp was about to explode.
Under the faint purple light at the bottom of the pool, Teng Qingshan saw clearly at a glance, it was a big boa constrictor as thick as a bucket! The scales of the boa constrictor's body are dense, with a faint purple halo, and the length of the cold pool boa constrictor cannot be determined for the time being, but the body of the boa constrictor that just passed through the underwater hole is more than six feet long.
In his previous life, he had killed the boa constrictor in the rainforest.
But there are such big ones with such thick torsos, he has never seen them before.
And... this boa constrictor rushed out of such a cold area, there must be something extraordinary about it.
"Roar~~" It was like the low, palpitating roar of a hurricane.
Following this low growl, the boa constrictor at the bottom of the pond rushed to Teng Qingshan at once, opened its bloody mouth, the big mouth of the big boa with the thickness of a bucket was a foot wide, and swallowed it towards Teng Qingshan!
