Thinking about this, Tang Yun immediately felt that his mood was calm, and he no longer had the previous impatience, seeing that the weather was getting hotter and hotter, and the rain was getting less and less, and before he knew it, it was the end of summer, so he decided to take his two younger brothers back to the abandoned mine to find the three big lizards to take revenge.

With this thought in his heart, Tang Yun didn't bother to choose a day, greeted the two younger brothers, and left the little mountain bag that had brought him a lot of luck.

All the way back to the small valley by the lake, Tang Yun didn't take much time to find the long and narrow passage that he had come out of, and after taking his two younger brothers through the passage for a long time, he came to the underground waterfall that made him tremble again.

The last time he came to this bottomless abyss where he could only hear the roaring sound of water and smell the water vapor that filled the cave, but he couldn't see the shadow of the waterfall at all, Tang Yun sighed at the mystery of nature more than once, and at this moment, he saw again that the shock of this bottomless abyss to him was still not weakened in the slightest.

Whether it is a bottomless straight pit or an underground waterfall that roars through endless years, it is a declaration of the greatness of the power of nature to all living beings.

Lying on the edge of the bottomless abyss, Tang Yun sighed with emotion, but at the same time, he was looking for the crack he had climbed up along the edge. Although he didn't know how high this abyss was, he was sure that if he fell, he would definitely die.

Therefore, if you want to return to the mine ruins safely, the most important thing is to go back the way you came, and only by returning along the rift when you came is the safest.

It didn't take Tang Yun too long to find that narrow crack, after all, this small platform was so big, it was really difficult to find it. Greeting his two younger brothers, Tang Yun leaned on the crack first, and carefully crawled down the crack.

The two cobras watched Tang Yun lie on the crack, and they both hesitated, but in the end they still followed, trembling and following Tang Yun's pace, not daring to cross at all.

Climbing on this almost straight crevice of the cliff was a very physically and energetic thing, and it was only when he saw the crack that connected the ruins of the mine that Tang Yun breathed a sigh of relief. After all, this hellish place doesn't touch the world, God knows if he took the right path, if he accidentally ran into another crack, then he would be miserable.

Tang Yun lay at the end of this crack, looking at the gap in Cave I not far away, the muscles on his body flicked violently, and with a "swish" sound, he accurately drilled into the crack.

Tang Yun, who had landed safely, sighed, turned around and signaled to his little brother, then retreated a few meters and gave way to his position, he believed that there would be absolutely no problem for these two wild cobras to jump in. It was indeed as he thought, and in less than a few seconds before he stepped back, two dark brown eyes came in one after another.

Seeing that his junior brother arrived safely, Tang Yun also breathed a sigh of relief, after all, what he was about to face was three big lizards, and there were two younger brothers to help and he single-handedly were two completely different concepts, if it was only him, he could only find a way to sneak attack, but with the younger brother as a thug, he could crush all the way with the attitude of a strong man.

Looking at his body size, which was more than three meters, and then at the two younger brothers who had reached two meters in length, Tang Yun suddenly burst with confidence, and walked along this naturally formed cave in the direction of the mine ruins.

There was no fork in the tunnel, and Tang Yun was not worried about getting lost, he shuttled quickly in the dark, and it didn't take long for him to come back to the neatly built underground cave.

As soon as he entered the mine with obvious artificial traces, a strong fishy smell came to his face, and after turning a bend close to 90 degrees, Tang Yun's keen thermal vision found that there were more than a dozen large rats with a length of more than 20 centimeters playing leisurely in the middle of the mine.

At the same time that Tang Yun found these mice, these rats also found these three big black snakes, and when they saw the rats of the natural enemy, they were quite panicked and screamed a few times and fled in all directions.

However, whether it was Tang Yun or his two younger brothers, they were all experts in exterminating rats, and when they saw these rats scattering away, they immediately moved, and their bodies stabbed out like lightning, leaving the three slow-running rats behind.

In the past few hours, it was rock climbing and rushing, Tang Yun and his two younger brothers were already a little hungry and panicked, and now that they caught these fat mice, they naturally would not be polite, and swallowed them one after another.

The rats in the ruins of this mine may be in contact with that magical blue crystal for a long time, and the nutrients and energy contained in the flesh and blood are very rich, and a rat has a stomach, which actually replenishes more than half of the physical strength consumed by Tang Yun before, and in terms of value, it is almost the top two big catfish.

Tang Yun, who had eaten and drunk enough, expanded his thermal sensing vision with all his might, carefully sensed the smell in the air, and then took his little brother towards the pit on the right.

After walking less than five hundred meters along the pit, Tang Yun found that a large number of rats had gathered in front of him, rushing towards him like a tide.

"Hey, it's this trick again, but your trick was a bit useful to me before, now...... I just hope you don't run too fast!" Seeing the rats rushing towards him in groups, Tang Yun muttered in his heart, and slid towards the rats without avoiding it at all.

A moment later, a tide of rats appeared in front of Tang Yun's eyes, but he grinned at the corners of his mouth and rushed into the rat swarm at a sharp acceleration.

"Squeak Squeak......"

When the rats saw that Tang Yun dared to rush towards them so swaggeringly, they immediately let out an ugly cry, and the rats that were close immediately turned around and pounced on him, and in the blink of an eye, the three-meter-long big black snake was drowned by the sea of rats.

"Hum—"

At this moment, a slight but penetrating vibration sound came from among the rats, followed by the painful howls of the rats before they died.

Before the rats came to their senses, there was another crisp sound of "bang", and the rats that had just pounced on Tang Yun's side had all been shocked to death, and even the corpses were thrown a few meters away by his tail.

This sudden change made the rats following behind involuntarily stop, but the rats that rushed to the front didn't have time to stop at all, and crashed straight towards Tang Yun.

A few more tremors sounded, and all the rats that were within half a meter of Tang Yun's body were all shocked to death!

Seeing this, the remaining rats didn't dare to get close to Tang Yun anymore, and they all bypassed the road, and walked towards the two big snakes behind Tang Yun who were obviously smaller in size and seemed to be better bullying.

Looking at these rats that made a detour, Tang Yun was a little admired in his heart, I have to say that these mice still have some IQ, at least they know how to pinch persimmons softly, but ......

"Hey...... These two little brothers of mine are not soft persimmons. Tang Yunzheng was thinking so in his heart, and he saw his two junior brothers stand up suddenly, and with their mouths open, large strands of blood-colored liquid spurted out of their mouths.

"Woohoo......"

The first few rats that touched the blood-colored liquid screamed and fell to the ground, and after a few convulsions, there was no sound.

The tragic appearance of the pioneers finally caused a riot in the rat colony, and in just a few seconds, the rat colony, which had just been as vigorous as a tide, retreated in a frightened "squeak", leaving only the corpses of the black-haired rats on the ground.

Looking at the corpses of rats on the ground, Tang Yun, who had not eaten enough, hurriedly swallowed the entire seven big mice, and then he felt that there was finally some stock in his stomach, and he did not immediately chase those rats or find trouble with the big lizards, but instead formed a ball in the same place and concentrated on digesting the food in his stomach.

The two black-brown cobras with a small number one were also like two big ones, and after eating them in the same way, one left and one right coiled on both sides of Tang Yun, faintly protecting him in the center, that look, just like two loyal guards.

After resting for more than half an hour, the three poisonous snakes that had regained their strength moved again.

Tang Yun took his two younger brothers into the mine with great momentum, wanting to find the three big lizards and kill them all in order to avenge the revenge that chased him like a lost dog.

However, after a few laps in the tunnel, Tang Yun sadly found that he was lost!

The remains of this mine cover a very large area, and the entire tunnel is dark, and there is no way to distinguish the direction, after drilling a few laps in it, Tang Yun felt dizzy, and after wandering around for half an hour, he completely lost his sense of direction, and could only judge the direction by the smell of rats from time to time in the tunnel.

In Tang Yun's perception, although this pit is gentle, there is actually a slope that is extremely difficult for human perception to detect, the more he goes in the direction of the strong smell of rats, the deeper he goes underground, after a few laps, Tang Yun himself doesn't know how many meters he is now deep underground.

And there is one thing that Tang Yun is quite concerned about, you must know that the weight of cold air is greater than that of hot air, in an ordinary cave, the lower you go, the lower the temperature will become, but this mine is subverting this physical law, he has been going deep underground for a long time, but the temperature has not changed in the slightest.

As Tang Yun went deeper and deeper, the surrounding pit forks became fewer and fewer, and in the end, they converged into a narrow and dark passage that could only be passed by one person, and at this time, the originally gentle mine tunnel suddenly turned into a bluestone step that plunged straight into the depths of the ground.
