Back at Lijiaao, Li Changqing stayed in the health center.

Several patients who had been bitten by snakes went to the clinic for follow-up examinations, and the wounds were still somewhat red and swollen.

Li Changqing once again used a silver needle to measure the blood, draining the residual toxins in the blood, and asked Li Hongdou to replace the patient with herbs.

Usual.

Li Changqing would immediately return to Zhongnan Mountain after he was busy with the things down the mountain, but he remained in the health center today.

"Brother Qing, aren't you going up the mountain?"

Li Hongdou was already accustomed to Li Changqing Shenlong, and asked suspiciously.

"You forgot, from today onwards you have to learn Chinese medicine knowledge from me!"

Li Changqing looked at Li Hongdou and said seriously.

"Okay!"

Li Hongdou was very interested in Li Changqing's amazing medical skills, and replied excitedly after hearing this.

"Here you go, I'll read it in a week, and I'll be familiar with it in half a month!"

Li Changqing threw Li Hongdou a copy of "The Basics of Traditional Chinese Medicine" published by Huaxia Publishing House, which had been prepared earlier, and said in a stern tone.

"Ah, the "Fundamentals of Traditional Chinese Medicine" published by Huaxia Publishing House?"

Li Hongdou took it in his hand and repeatedly confirmed that it was exactly the same as the common Chinese medicine textbooks on the market.

"Hmm!", Li Changqing nodded.

"Brother Qing, your medical skills are excellent, shouldn't you give me this cheats or something?"

Li Hongdou's eyes couldn't hide his disappointment, and asked stupidly.

"You can't understand this cheats to you, the road has to be taken step by step, the meal has to be eaten in one bite, take your time!"

Li Changqing glanced at Li Hongdou and said in a warning tone.

"Okay!"

Li Hongdou felt that what Li Changqing said was reasonable, and he could only accept the facts.

And in the Dongfeng Tea Field, Lu Qian took Chen Yaru and others down to the cross-shaped ravine.

The ravines are overgrown with knee-high weeds, and there is wet mud below, separating the four peaks.

"If that's expected, the entrance to the tomb is nearby!"

Lu Qian held the compass in his left hand, and the pointer on the compass pointed just forward, and said very firmly.

"I'm about to unveil the mystery of the ancient tomb of Dongfeng Tea Farm, can you find the clues to grandpa's mysterious disappearance?", at the critical moment, Chen Yaru was inexplicably nervous, but she immediately strengthened her belief that she must fulfill her grandmother's last wish, took a deep breath and said to Xie Manshan and the others: "Let's go forward and take a look!"

"A well!"

When Chen Yaru waited until the center of the cross ravine, she picked up the surrounding weeds and revealed a square ancient well paved with bluestone bricks.

The mouth of the ancient well is about one meter wide, and the four sides correspond to the four surrounding mountains.

"How can there be a well in a barren mountain and a wild mountain?"

"Could it be that this well is the entrance to the ancient tomb?"

Several students followed the instructor for the first time on a field trip, and they were very curious to see new things.

Chen Yaru and the others all set their eyes on Lu Qian, wanting to be confirmed by authoritative figures.

"No matter which direction it takes, the compass needle points here, and this well is the entrance to the ancient tomb!"

Lu Qian didn't say a word, and directly put the compass at the mouth of the well, and the pointer on the compass kept turning and turning, and then he said with a sigh of gold.

"If the mouth of the well is the entrance to the ancient tomb, there should be a secret passage underneath!"

Xie Manshan has studied the structure of the ancient tomb quite a lot, and guessed.

"It rained heavily last night, and there wasn't much water at the bottom of the well, so there must be space underneath!"

He Guangyao took out a strong flashlight and said affirmatively after shining it at the bottom of the well.

"Send someone down to test it, Wang Qiang will be you!", Xie Manshan said in an unquestionable tone to a sturdy student he had brought along.

"Ahh

Wang Qiang was shocked when he heard this, but it was not good to disobey his mentor's orders, and as a research institute specializing in archaeology, he would eventually face this kind of situation.

"Let's help you tie the rope, shout if there is any situation, and we will pull you up immediately!"

The remaining students took out special tools from their schoolbags and put them on for Wang Qiang.

"Okay!"

Wang Qiang's newborn calf is not afraid of tigers, and he is not deeply involved in the world, so he does not know the danger of this kind of behavior at all, except for some nervousness, he does not feel afraid.

Several students helped pull the rope, and Wang Qiang grabbed the rope and slid down the well.

The walls of the ancient well built of bluestone bricks are covered with moss, and they are about to approach the water surface after falling four or five meters, but Wang Qiang still does not see the so-called secret passage.

"Teacher, I didn't see the secret passage!"

Wang Qiang used his hands as a horn and shouted towards the well.

"Is it in the water at the entrance? Then you have to drain the water first!", Xie Manshan said with a frown.

"Look at the wall of the well below, is there anything different!"

Although Lu Qian is not engaged in archaeological research, as a master of the feng shui world in Wen'an City, his experience in going down to ancient tombs is definitely much richer than that of an academic school like Xie Manshan.

"Hey, there's a blue brick recessed in!"

Wang Qiang listened to Lu Qianyi's words, carefully observed the wall of the well, and found subtle differences.

"Press the green brick that has been recessed!"

Lu Qian looked like this was really the case and continued.

"Good!"

"Click, click, click......"

Wang Qiang followed Lu Qian's instructions and pressed the blue bricks recessed into the well wall, and suddenly there was a sound of mechanical friction.

The bricks popped out, and the nearby walls shrank inward, then moved away to reveal a tunnel.

"Haha, there really is a secret way!", Wang Qiang said excitedly.

"Old Lu, you have saved a lot of things, otherwise I would still be digging all over the mountain to analyze where the ancient tomb is!"

Although Xie Manshan used to be the vice president of Jianghan University, and now he is the dean of the School of History of Wen'an University, and the main person in charge of the Dongfeng Tea Farm excavation project, he knew very well that their actions mainly depended on Lu Qian, and he also very much agreed with Lu Qian's ability, and said with admiration.

"You can find the ancient tomb with a compass, which can only be described by the word 'magical'!"

"I've only seen it on TV before, but I didn't expect someone to be able to do it in real life, Master Lu is amazing!"

Several archaeology students were amazed and admired Lu Qian to the extreme.

"Lu Lao really lives up to his reputation!", Chen Yaru was also very happy.

"Strange, not a single snake!"

When everyone was excited to find the entrance to the ancient tomb, He Guangyao felt that something was wrong, when he first surveyed the Dongfeng Tea Field, there were still many snakes on the periphery, and I heard that Li Jiaao had just broken out of snakes yesterday, but they immediately arrived at the entrance of the ancient tomb, and the snake shadow was not seen.

"What's so strange? It's just a few little snakes, and if you're next to me, they naturally don't dare to get close!"

Lu Qian spread out his palm, and there was a palm-sized dark red jade talisman, which was engraved with strange runes of different shades.

"Yang Talisman, Uncle Shi, can you make a Yang Talisman?"

There are many factions of Feng Shui, each family has its own strength, He Guangyao's Zhongjiang Jiangnan vein was once famous for making jade talismans, yang talismans can drive away evil spirits, and belong to the top grade in jade talismans, but the difficulty of making is also extremely high, and it has been lost for decades in Zhongjiang Nanmai, but I didn't expect it to reappear in the hands of his uncle.
