Even scientists were unable to determine the reason for their changes. In the end, they could only attribute it all to human evolution. Of course, this would come later. The night that Lin Yan arrived, he entered the tropical rainforest and directly went to the dried up well.

The dried up well was still there. When Lin Yan walked closer, he did not hear any sound.

He took out a piece of rope and tied a candle, tossing it down. The bottomless height of the candle instantly dimmed the flame. He put on an oxygen mask, tied one end of the rope to a hundred-year-old tree nearby, the other end to his own waist, and slowly went down the well.

His feet treaded on the wet walls of the dry well. Despite his martial arts, he didn't dare to jump into the well immediately.

He felt that the dried well was much easier to enter, but there was another problem. The dried well was too deep, and the rope quickly ran out. Lin Yan hesitated for a moment, and then suddenly stuck his foot into the crack in the wall of the dried well. He turned on the searchlight above him, and discovered that the dried well had crevices in the wall that looked like stairs that could be climbed with his feet.

His entire body was as light as a swallow as he jumped down through the cracks in the wall. The dried well was very deep, and Lin Yan felt that he had fallen at least two hundred metres.

He thought about it for a while and felt that it made sense. How much oxygen could a two hundred meter high well hold?

After putting on the oxygen mask again, he continued to walk down.

However, something that surprised him happened. The well suddenly changed its direction and became a road that ran horizontally. According to the ground as a reference, that road should be 300 meters below the ground, parallel to the ground.

Furthermore, Lin Yan lit a match to test it out. The match actually had flames burning until it was completely burnt out, which meant that the oxygen here was abundant! But how could this happen?

Lin Yan walked forward in surprise. He put away the oxygen mask to save more oxygen, and very quickly, he reached the end of the road, and walked a lot of different paths. Without exception, all of them were single paths that did not require a choice, and also confirmed that there was sufficient oxygen in the air below.

Suddenly, a door that was as tall as three people appeared in front of Lin Yan. High above the door, there was a black board with three words written on it.

Lin Yan, who had already made all his preparations, did not hesitate at all. So what if he was in the gates of hell, he was not afraid of the eighteen levels of hell! As long as he could meet his parents and Li Mi, and bring them out, he would be willing to pay any price!

The door was pushed open. It was not like what Lin Yan had expected, there were monsters everywhere, and the inside was as clean as any other street.

Because it was night, it was empty.

There were even hotels and restaurants and a 24-hour convenience store. Lin Yan walked into a convenience store and discovered that their things also had quality identification marks. The production date was also the same as the outside, if not for the two words that made people suspicious, he felt that they were no different from the outside.

"Boss, the bill!"

Lin Yan felt thirsty and took a bottle of water to the cashier, "Hello, five pieces!" The boss of the cashier opened his mouth wide as he received the RMB from Lin Yan, "Boss, we only accept people who swipe their cards!"

"Oh!" Lin Yan handed over his credit card. When the owner swiped the money, other than not taking the RMB, the exchange rates were all the same. Lin Yan thought this as he walked out of the convenience store.

The amount of money in his bank account was enough for an ordinary person to spend for two lifetimes, so he didn't worry about not having enough. He went straight to the hotel and booked a room according to the date of the year.

"Boss, do you need any other services?"

After bringing Lin Yan who did not carry any luggage to his room, the waitress asked delicately.

Lin Yan felt that the more knowledge he had about the place, the better, so he nodded and asked with interest, "What other services are there?"

"We also provide bed service. It's calculated by day and by year." The waiter's face was slightly red as he whispered. Lin Yan pursed his lips and thought that it was their wake up service! He could not use it at all. Just as he was about to tell the waiter that there was no need for it, he raised his head and opened his mouth to form an "O" shape.

The waitress's clothes had already been completely stripped. Her body was white and tender, her skin as smooth and exquisite as congealed oil. Her chest was very big and very soft. One look and it was easy to tell that it was very elastic.

She took off her high heels and stockings, walking towards Lin Yan step by step as her chest rose and fell, filled with enticement.

"Boss, do you want to calculate it by the day or the year?" Without the slightest shyness, she laid down beside Lin Yan, touched a certain part of Lin Yan, and "ah" twice.

The voice was soft, seductive, and full of enchanting charm.

Lin Yan was completely petrified. So the service that the beauty was talking about was not the same as the one he was thinking about!

"Boss, go ahead!" The woman asked again. Her long legs moved back and forth on Lin Yan's leg, calling out twice, as if she was already high up in the air.

" I don't need it! "

Lin Yan really didn't mean it that way! He really just wanted to know more about this place. Who knew what other services were referring to?

When the beautiful woman heard his words, she stopped her actions. Tears instantly poured out from her eyes, as her delicate body caused others to feel tender towards her.

"Boss, did I call it bad?" she asked.

"No, no, no!" Lin Yan was so scared of that she cried! I'm just not used to people in my bed! Don't cry, if you need a quota, I can agree to Bao Nian's services, but you don't need to do that. If you need to deal with other people's checks, you can just obediently sleep on the sofa outside … Or I could sleep on the couch! "

Allowing a gentle woman to sleep on the sofa wasn't Lin Yan's style at all. He got up helplessly, but he didn't expect that he would actually reserve a room … It was actually a sofa with a reserved room!

Sigh! Who asked him to be soft-hearted!

The woman stopped crying after hearing his words. She looked at him curiously and started to giggle.

"What an interesting person!" The beauty smiled, got up and put on her clothes, "We do have a mission, so I won't be polite. As for you not needing this service, I can replace it with something else! Do you need anything else? My massage technique is also not bad! " The beauty blinked her mischievous eyes. "I even know Thai massage!"
