Chapter 47：

Hannah said happily: "Sean, this is good news, because this may be the way out to the old mine."

"How deep is this pothole?" Sean asked.

Trevor said to Hannah at the side: "Give me a flare, Chen, look at your watch."

Chen Muyang said: "Hannah, you'd better give Trevor a light stick, because there is magnesium in the rock formation. If you are not careful, it will collapse and kill us all."

Trevor checked quickly and exclaimed, "It's really magnesium, Chen, you saved everyone's life."

Hannah handed the light stick to Trevor, and Chen Muyang looked at the watch to time the clock, and finally calculated that the height of the pothole was about 200 feet, which is 61 meters in meters.

"Are there enough ropes?" Trevor asked.

"Don't worry, I only have 150 meters of rope here." Chen Muyang said with a smile.

Although there were some accidents during the rappelling process, everyone reached the bottom smoothly in the end.

After packing up the ropes, the four continued to set out to explore, and soon found the abandoned mine tunnel. There is no better news than this, which means that everyone has a chance to go out.

"Wow, look what we found, an old-fashioned generator." Chen Muyang said in surprise.

Hannah came over and tried to activate it, Trevor kept muttering beside him, no good words in his mouth. But Hannah managed to activate it, and the electricity flowed and the light illuminated the entire mine.

"Nice job, Hannah!" Chen Muyang praised and gave Hannah a high five.

Trevor smiled dryly beside him: "OK, I take back what I just said."

Sean looked at the mine road happily and said, "This is the way out. The miners have to transport the ore they dug out. Follow these tracks and we can get out."

Trevor asked Hannah, "How many absenteeism escaped from the mine disaster?"

"One." Hannah said a cruel number seemingly casually.

Hannah found the human-powered rail car, and Chen Muyang found the steel bar to make a three-phase hook, then took out the rope and tied it to the end, shook it a few times and nodded with satisfaction.

"What's the use of you doing this, Chen?" Trevor asked curiously.

"Of course it's an emergency at a critical moment, Trevor, you go to the front with Sean, he might be scared as a child. Hannah, you take the minecart in the back, and I'll push the railcar."

Sit up as Chen Muyang said, and Chen Muyang started to start the human-powered rail car.

"Welcome to the roller coaster!" Chen Muyang shouted.

Before the three of them understood what he meant, the minecart suddenly slid down as if it were falling, and it turned out to be a big slope!

Driven by the acceleration of gravity and the railcar, the speed of the minecart is astonishing, and it gallops rapidly on the rails, which really feels like a roller coaster.

Soon, there was a big bend in front, and you could see that the rail was broken!

"Brake! Chen, brake quickly!" Trevor yelled in horror.

"It's too late, I can only speed up!" Chen Muyang shouted and accelerated again.

At the break of the rail, the minecart flew up, crossed the break several meters away, and landed on the opposite track.

The three immediately cheered excitedly.

Before I was happy, there was a three-way intersection in front of me. Trevor and Sean's minecart entered the right track, Hannah's minecart went straight forward into the center track, and Chen Muyang's human-powered railcar entered the left track. side track.

Chapter 50 There are many treasures in the center of the earth

After turning a few corners, Hannah suddenly exclaimed: "Chen, there is no track ahead of you!"

Chen Muyang immediately made a decision and jumped into the minecart where Hannah was. But there was no front of the track, Chen Muyang quickly tied the rope to the hook on the waist of the two, and then threw the three-phase hook violently.

click! The three-phase hook instantly hooked the sleeper, and the two bodies were driven to fly up by the reaction force, while the railcar galloped straight forward and slammed into the rock wall at the end.

Chen Muyang turned over and landed thoughtfully, letting Hannah lie on top of him.

Hannah looked deeply into Chen Muyang's eyes, Chen Muyang's foresight to make a three-phase hook, the jump on the way, and the last turn over, such a man with foresight, courage and thoughtfulness is very exciting to women.

Chen Muyang looked up and kissed Hannah's red lips, Hannah responded enthusiastically.

In the sound of friction, the mine cart that Trevor and Sean were riding in stopped next to him. Trevor saw Chen Muyang and Hannah kissing, and a trace of sadness, envy and jealousy flashed in his eyes.

Hannah was thin-skinned, and when the two came, she let go and Chen Muyang stood up.

Originally it was supposed to be the end of the mine, but the mine cart that Hannah and Chen Muyang were riding hit the rock wall, and a hole was knocked out, which meant that the front was empty.

Drilling through a sufficiently wide gap, Chen Muyang exclaimed in surprise, "Wow, rubies, emeralds, diamonds! This is a veritable gem mine!"

Chen Muyang immediately began to collect the exposed diamonds on the rock wall, and Sean immediately followed.

Trevor and Hannah were watching the situation, not interested in these gems.

Chen Muyang collected a lot of gems, and when his eyes swept across a pitch-black rock, he was overjoyed: "It turned out to be black gold and iron, this is the top-grade material for refining magic tools."

Grabbing the black metal iron in his hand, his infuriating energy moved, and the black metal iron, which was the size of a basketball, was instantly taken down.

But the heavy black gold and iron also crushed the mica under Chen Muyang's feet, the ground shattered instantly, and the four of them fell down.

The sudden change made Hannah, Trevor, and Sean terrified, and screams echoed in the cave.

Chen Muyang put the black gold iron into the system warehouse, then reached out and grabbed Hannah into his arms.

Trevor grabbed his nephew, and Sean asked, "How deep is this hole?"

"According to the description of the novel, the tunnel is thousands and hundreds of miles deep!"

Converting a mile into a kilometer is 1.6 kilometers, which means that this cave is several thousand kilometers deep!

Obviously, this is not possible.

"Trevor, what's under there!?"

"The stone wall may be gradually eroded by the water inside, allowing us to gradually slow down, a bit like a water slide!"

Hannah exclaimed, "But doesn't water make stalagmites at the bottom?"

Chen Muyang exclaimed: "Of course it is possible, if it is as you guessed, it can only depend on our luck."

After falling for quite a distance, the water slide that Trevor was talking about finally appeared! The current protects them as they rub against the rock wall, reducing their speed rapidly.

Finally, the four fell into a pool at the bottom.

Chen Muyang hugged Hannah and quickly swam to the bright place in front, while Trevor followed closely behind with Sean.

After getting out of the water, Chen Muyang carried Hannah ashore, put her down, and sat down beside her.
