"What the hell is this bat!" Xu Li said in surprise, "How can you grow so big!" ”

"This is a flying fox, the largest of the bats, but I remember that flying foxes eat fruits, why do they bite people and suck blood now?" I say.

"That's no ordinary flying fox!" It was Professor Li who spoke, "This is a special branch of flying foxes, called blood flying foxes, also called blood bats. In fact, this was originally an ordinary flying fox, but it was domesticated and turned into a blood bat! ”

"What? Do you mean that someone trained a flying fox that would have eaten fruit to suck human blood? I asked in surprise.

"Yes!"

Everyone looked at Professor Li in amazement.

"According to the historical records found today, the first person to domesticate the blood bat was Zhao Tuo, the first monarch of the Nanyue Kingdom." Professor Li said, "In order to prevent the tomb from being disturbed by tomb thieves after death, Zhao Tuo domesticated a group of blood-sucking flying foxes to guard the tomb. And a large number of blood bats also appeared in the tomb of Zhao Yu, the second monarch of the Nanyue Kingdom, found in Yuexiu. The first discoverers of the tomb of the Nanyue kings were not fully prepared at that time, and most of them were sucked to death by blood bats, and only a few escaped.

The methods of domesticating blood bats are quite cruel. At first, the fox cubs were fed with fruit, and then they were fed with fruit mixed with human blood. As he grew older, he began to feed human blood. Finally, when the flying foxes are close to adulthood, they will tie their hands and feet and throw them into the fox's hole, allowing them to suck their blood to their heart's content. When they reach adulthood, flying foxes will pounce on people. Finally, there is the test, the trainer will throw a group of living people into the fox burrow, if the flying fox can kill everyone, then these flying foxes are qualified, and they will be turned into blood bats and placed in the tomb to protect the coffin or treasure of the owner. ”

"These blood bats will die too! It is impossible to protect the tomb forever! I said.

"Blood bats have a strong learning ability, and their cubs learn from their parents' blood-sucking habits, which are passed down from generation to generation. Blood bats are social creatures that can quickly form large legions of blood bats after breeding. As long as the cave is not destroyed and the surrounding food supply is sufficient, the blood bats will basically survive from generation to generation. Blood bats usually only eat fruits, or eat some small animals, such as mice, fish, etc. They do not hunt medium to large animals, but they can suck human blood and pounce on people, and they are specially trained killing machines.

A few years ago, the sensational blood-sucking zombie attack in Guangxi was confirmed to be the work of blood bats. At that time, a blood-sucking corpse was suddenly found in a small village in the east of Guangxi. Later, people were attacked by bloodsucking killers one after another. Those who were lucky enough to escape their lives said that it was the work of vampire zombies, which caused panic for a while. The matter was discussed in newspapers across the country. Later, the central government was alarmed, and the central government sent experts to the village to investigate. Finally, a large tomb was found in a deep mountain a few kilometers from the village, which was inhabited by thousands of huge vampire bats. It was the largest drought on record. The blood bats could not find food nearby and had to go farther away to feed, and then saw the villagers, and their blood-sucking instinct was stimulated, and then attacked the villagers. In the end, the central government sent a well-equipped army to wipe out all the blood bats.

The blood bats here all seem to be able to climb and not fly, and it is estimated that there is enough food in the cave so that they don't have to go out to hunt, so their wings are degraded! ”

"If there are blood bats here, there should really be ancient ruins. It could be a tomb, or it could be some important secret! Master Zhang said.

"But the road here is bizarre!" I said, "Two roads in opposite directions with no turns lead to the same place, and it's a dead end." How do we do it? ”

"Professor Chen, Master Zhang, and I have discovered the secrets of these two strange paths in our research just now." "According to this secret, it is possible for us to find a way to the underground ruins!" ”

Professor Li's words made me quite curious. I'm curious to see how those two paths come together. I'm definitely not the only one who is also curious, and I guess everyone wants to know the secret.

Xu Li hurriedly asked Professor Li, "What is the secret?" How can you find the ruins that lead to the underground according to this secret? ”

"This is an architectural problem, let Professor Chen, an expert in this area, talk about it!" Professor Li said.

When Professor Li talked about Professor Chen, I remembered that there was such a person. The man had been silent all along, and he had never been seen to speak. Although I always see him, I subconsciously seem to be transparent. It's like you see him every day, and when people ask him what he looks like, you can't remember what that person looks like. It's a kind of subconscious ignorance, because he doesn't usually make much of an impression, so looking at him is like looking at a tree, a building so mundane and forgettable.

"I'll explain it to you!" Professor Chan said.

As soon as Professor Chan spoke, I knew why he was usually reticent. Because his voice lacks the thickness and majesty that an adult man should have, but is close to the tip and immaturity of a child. This kind of voice would make people think very cute if it was a girl, but it would sound funny if it was replaced by an uncle in his thirties and forties. In medicine, this is called voice dysplasia. His voice may be a congenital problem, or it may be acquired by external stimuli, so it is not fully developed. I saw a scar near Professor Chen's throat, which was probably due to the acquired cause.

"Actually, when we entered one of the forks, the road began to turn! The two roads are connected in the middle. Professor Chen said. His high-pitched voice came out of the mouth of a big man, and it struck me as strange.

Everyone was amazed.

"What do you mean by that?" I asked.

"It's an optical illusion!" "Because the road here is special. There were obvious traces of man-made excavation when entering the fork. That's because someone deliberately made the first half of the two roads exactly the same, in order to confuse people's vision. There are two other deceptive places. First, it's designed to be wider as you go back, so it's hard to spot a turn. Second, the walls on both sides of the road are deliberately polished to be quite flat, which gives the illusion that you are walking on a straight road. Many ancient ruins or princely tombs will have this layout, in order to make the invaders think that the ghost is hitting the wall, and finally flee in the wilderness! ”

"What a professor-level character!" The commissioner said, "This is not a ghost hitting the wall, don't scare yourself!" ”

Everyone looked relieved.

"Professor Chen, you just said that according to the secrets of these two paths, it is possible to find a passage to the underground ruins! What do you say? I asked.

"This has to be explained by Master Zhang, an expert in metaphysics!" Professor Chan said.

"Your division of labor is really clear!" Ma Liu said, "One finished talking and then the other! ”

"Everyone who is called in will have their own use!" Professor Li said, "The government will not recruit people who are useless for the task!" ”

"That's right!" Ma Liu said, "Master Zhang, please tell me your opinion!" ”

"I found out just now that these two roads are laid out according to the Liangyi Formation." Master Zhang touched his beard, "This is a more basic element that produces gossip. As the saying goes, 'Taiji gives birth to two rituals, two rituals give birth to four elephants, and four elephants give birth to gossip'. The two instruments represent heaven and earth or yin and yang, while the two roads at the fork represent yin and yang, the yang road on the left and the yin road on the right. But the two roads are connected to the same place, which means that yin and yang combine to produce four images. The four elephants can represent many things, but here they represent the four directions of east, west, north and south. Master Zhang walked to the wall behind him with a flashlight, as if looking for something, "The four directions are up, north, down, south, left, west, right and east from the plane. All that's left is how to determine the direction of the target! ”

"Master Zhang, what are you looking for?" I followed.

"Found it!" Master Zhang's flashlight stopped on an ordinary stone protruding from the wall.

At this time, everyone also came over.

"What is this?" I asked, "Is it the switch that opens the channel?" ”

"Definitely!" Master Zhang said, "That's the builder's sign pointing the way!" ”

"What?" I was surprised and said, "It's just an ordinary stone, nothing special." ”

"What's special isn't what it looks like! What's special is the location it's in. The fingers of Master Zhang's right hand kept moving, as if he was calculating something, and he didn't know what he was talking about. I heard that people who study metaphysics like to use their fingers to calculate specific dates and directions, "and it happens to be in one of the hardest places!" ”

"What's the hardest part? Where is it? I asked.

"I followed the instructions and calculated that the stone was on the north side, that is, above!" He pointed to the top of the cave more than ten meters high, "It seems that the designer is a first-class master!" ”

"You mean the entrance to the passage is at the top of the cave?" I said in surprise.
