"There are four major springs in Boshan District, Shentou, Qiugu, Zhulong, and Liangzhuang, and there are seventy-two famous springs in Jinan, a small spring city, and thirty-six famous springs in Boshan, a small spring city. In the past, the streets and alleys of Boshan were full of bubbling springs. Ancient poems once used clear streams to pass through the city, and there are springs everywhere to describe the spring water of Boshan. Dr. Liu told everyone that the Shentou Spring Group, including Lingquan (Filial Piety Spring), Dahong Spring (also known as Baiyun Spring), Xuelang Spring, Yijia Spring, Yaowang Spring, Luquan Spring, Toad Spring, Hail Spring, Zhili Spring, Liulin Spring, Longwang Spring, etc. are the largest spring groups. Lao Ma and others said that the closest thing to the spiritual spring outside the big temple is Xuelang Spring.

It is said that the source of the filial piety river is the spiritual spring - the filial piety spring, but in the southwest of the spiritual spring, there is also a poplar river, which flows into the filial piety river, which is now also called the filial piety river. Xuelang Spring is on the Poplar River. Their original plan was to dive down from Xuelang Spring, enter the water system at the bottom of Boshan Mountain, and then enter the bottom of Lingquan.

But Lao Ma suggested that it be divided into two steps, the first step is to enter the flood channel outside the Lingquan to see if there is a chance to dive directly into the Lingquan, which is not only the least dangerous, but also the closest road. As an alternative, after this road is blocked, then I have to dive into Xuelang Spring.

Everyone nodded their heads. Lao Bo looked at this group of people, and suddenly felt very strange. A few months ago, except for Lao Gang, he didn't know anyone, and suddenly got together, and he actually wanted to explore the secret Boshan Spiritual Spring? plus himself, there are a total of 8 people in this house, Lao Ma, Doctor Liu, Liu Laoxiao, Lao Gang, Big Tiger, Second Tiger, what, this kind of thing, brothers don't believe it, let alone such a friendship. Lao Bo felt a chill in his chest, he framed him twice in a row, it is estimated that this retribution is coming.

It doesn't matter if a person does a bad thing, it is not difficult to do a bad thing for a lifetime, but the difficult thing is not to be weak-hearted.

"In this -10 degree weather, I had to get two wetsuits to protect against the cold. When the time comes, you four young people, see who will go down? The old horse looked at the big tiger and the second tiger, and the old man was bored and old.

It's still the problem of how to cross the river safely with wolves and sheep and a pile of forage. Lao Gang will never go down together, and the two tigers will not go down together, Lao Gang has a holiday with the two brothers of the big tiger, and if he goes down with any of them, everyone must not be at ease. Then there is only one of Lao Bo and Da Hu and two tigers.

"Maybe there's nothing in there, you don't have to grab it, it's like you're going in to move the baby." The old horse deliberately joked, he must have hoped that there would be a rush into the water.

"I think I can explore the spiritual spring tonight." Dr. Liu suggested that he felt that the first time he went, he could first see if there was an alarm device inside, and he didn't need to go into the water, so he could travel lightly, mainly to explore the road first and find out the situation inside.

Lao Bo knew that the people who explored the path this time would dive in the future if there was no accident, so he volunteered, "How about me and the big tiger?" ”

"No, now Dahu has a special identity, he is a forest farm worker, in case the monitoring is recorded, our plan to enter the forest farm will be ruined." Lao Ma let Lao Bo and Erhu enter the flood channel, and the two put on headlamps and brought video recorders, mainly to take pictures of all the situation inside.

"There is a problem here, someone needs to go to the Xiaonu River in the flood channel in the afternoon to open an opening to see the situation." Dr. Liu said that since it is a national key cultural protection unit, this kind of place will definitely have external protection. Let's see what's going on first.

"I know this too well, leave it to me." Lao Gang originally wanted to sign up to drill this cave, and he liked to run in the river and jump up and down the mountains since he was a child. There are a total of three or four air-raid shelters in the whole city of Boshan, and there is no one he can't enter. Basically, all the bomb shelters have an exit leading to the Xiaonu River, because they have been drilled all over by him, so they are very familiar. "These exits to the Xiaonu River are all with iron fences, usually chains or iron locks. It is also relatively easy to open. ”

"You can't do destructive unlocking, you smashed the lock, which gave a notice to the Boshan Cultural Relics Bureau, and someone is worried about the things of the big temple." Dr. Liu is firmly opposed.

"This is easy to do, I'll go right away, I guess it's either at the ticket office of the Great Temple, or at the river management office. I have classmates and buddies in both places, so I just went to them and talked, and I was able to do it. "Lao Gang really didn't brag, basically Boshan people who are about the same age, and they all have more or less classmates and buddy relationships. If you haven't gone to school together, you must have fought together back then, especially like Lao Gang, who walks the streets and alleys all day long to repair screens and cast sewers, which is even more connected.

At three o'clock in the afternoon, Lao Gang sent a text message to Lao Bo, and it was done!

After receiving Lao Gang's text message, several people looked at each other, this guy is amazing, isn't his IQ always not very online? It was really done in such a short time. Everyone set to gather at 12 o'clock in the evening in a park on the bank of the filial piety river opposite the temple, Lao Ma and Dr. Liu listened to the news at home, Lao Gang and Dahu answered outside, and Lao Bo and Erhu began to explore the cave at 1 o'clock in the morning.

At 12 o'clock in the evening, the snow fell in the mountain city, and the old stuffy was in a very good mood when he went out, the haze was blown away by the north wind, and the clean air was cool and fresh. It's the warmest time of the year, because everyone doesn't go out to practice, everyone is huddled at home, with the people closest to them. If there is no pressure of life, you will always be with the people closest to you...... But Lao Bo and Mrs. Yan hardly talk much now, and the peacock is also very estranged from him, he can only talk to a few suspected criminals, and he will be cold and cold outside tonight.

The four of them met in a small park along the river, and Lao Bo and Erhu prepared a cycling scarf to cover the area below their eyes, and wore a black thread on their heads, looking like two bank robbers. Lao Bo is even more exaggerated, and he also tied a rappelling rope to his body, as if he was going to dive that night.

"When I came during the day today, I found that the fence gate of the Lingquan flood channel was locked. Here's the key. It seems that this thing is not used every day, I took it directly from the duty room, and from the time I took it to the time I went back with a new key, they didn't find it. "Lao Gang handed over the key to Lao Bo.

The temperature tonight is minus 3 degrees Celsius, which is not too cold, but yesterday it was minus 10 degrees Celsius. At one o'clock in the morning, everyone fell asleep, and occasionally a few nocturnal cars sped along the river. At this point, except for the police on patrol, ordinary people will not go out for a walk on the street. Lao Bo and Erhu went down to the bottom of the river, and along the sewage closed cover on both sides, they came to the Lingquan flood outlet. On the iron fence is a three-ring lock, Lao Bo first opened it with the key, sure enough, the lock has long been rusted, and then took out the prepared engine oil and lit it on the key, and then opened it a few more times. Soon, the lock snapped open.

This passage is all made of bluestone, which has been washed by floods for thousands of years, and these bluestones have revealed a soft stone-like texture, shining with cyan brilliance under the illumination of the light. The top of the cave is about 1.6 meters high, and Lao Bo and Erhu have to bend down and walk forward. The floor of the passage was dry, and the headlamps shone off rising dust. It seems that there has been no water here since the beginning of autumn. Lao Bo was surprised that there were basically no protective measures in the cave, and there were no iron fences and iron gates at the exit, let alone monitoring and anti-theft facilities.

By the way, this was originally used to discharge floodwater, and nothing can be put in it, otherwise wouldn't it all be soaked? The old man nodded secretly. Coming to the exit at the other end of the passage, Lao Bo motioned to the two tigers to turn off their headlights, and at this time, they had already uploaded the video to Lao Ma and Dr. Liu. Dr. Liu instructed the two to take two more photos on the cave wall two meters away from the exit through a text message, especially the condition of the ground, which must be taken clearly. Lao Bo immediately understood that what Dr. Liu meant was not to go out of the cave, but to open the ground directly from the passage and look for the entrance to the underground water system. It is less than three meters away from the Lingquan Spring, and if there is an entrance to the underground water system, then this is indeed the closest distance.

Lao Bo found two meters away from the exit in the cave, and sure enough, he found a little abnormal, there is a two-meter square stone on the ground, which looks more special than other stones, and the other paving stones are half a meter wide and one meter five long strips of bluestone, only this one is a dark yellow granite.

Lao Bo took this stone down and passed it to Dr. Liu and Lao Ma.

"Great, it's him, this kind of stone seems to be called the door stone, which is generally used at the gate of the noble eunuchs of the Qi Kingdom. Finding such a stone here means that we are looking for the right direction. Dr. Liu continued to send a message, "It is generally believed that this big temple was built by the Tang Dynasty, when the Tang King Li Shimin led a large army to pass here, and the soldiers were thirsty. Grandma Yan sent a jar of water, but the whole army drank it, and the water in the jar did not decrease. Li Shimin, the king of the Tang Dynasty, promised that after he returned, he would build 99 beamless halls for the local gods. Later, due to the limited space here, 9 rooms were built. From what we have seen, it should have been earlier. ”

Lao Ma sent a message asking Lao Bo and the two of them to observe the situation in the big temple again, and then they could evacuate.

Lao Bo and Erhu squatted at the entrance to the water and listened to the sound above, which was only a dozen meters away from the doorman, and the sound of the security guard watching TV in the communication room was clearly recognizable. Although it was almost two o'clock, the security guards did not sleep, at least the TV did not sleep. Lao Bo sent a text message and asked Lao Gang to throw a stone at the entrance of the big temple.

"Bang!" Five minutes later, he heard the sound of stones hitting the door panel.

"Who?" I only heard an inquiry in the communication room, Lao Bo and Erhu held their breath, and after five or six minutes, only the sound of the TV came from above.

The two smiled at each other and quietly evacuated the flood channel.
