But Tang Chizhou didn't dare to tell his father and grandfather the truth, because he knew that once his father and grandfather knew the truth, they would definitely try their best to stop him from going. Tang Chizhou just told his family that there were three medical school scholars from American universities who came to China to study Chinese herbal medicine, so he wanted to go with them and learn and exchange by the way, and repeatedly emphasized that this was a rare opportunity to learn and exchange.

After a brief introduction and a short exchange, the professor was very satisfied with this candidate, because Tang Chizhou was educated in the United States, and had a cheerful personality, active thinking, and the courage to take risks, but he was not reckless, thoughtful and meticulous, and a very alert and capable young man.

The professor has been teaching for decades and interviewing countless students, so he can always quickly and accurately detect the many qualities of a person in a relatively short period of time.

As the Western proverb goes, "A good start is half the battle", and choosing such a key role right is certainly a good start, because the professor has increased his confidence in this expedition. Of course, this is all due to the great help of the Feng Shui master's family, and the professor feels that he is very lucky to meet such enthusiastic people as the Feng Shui master's family during this trip to China.

Because of the long distance, the four of them did not delay, and after preparing the required expedition equipment in full swing, they immediately set off by train.

Because at that time, our generation had not yet connected to the railway, so they could only go to the provincial capital, and then completely rely on walking, like ours in the mountains of the difficult trek, but it happened to be autumn, the weather was not so hot, the autumn breeze was cool during the day, and it was already slightly cold at night, and it was necessary to cover a thin quilt. The weather was very favorable for the journey, so it took the three of us a much shorter time than expected to reach the foot of the mountain in our area.

In the process of trekking in the mountains, they hired two porters and a guide, but because the equipment was really a lot, and the speed of their march was very fast, the two porters were so tired that they were so tired that they just walked for two days, and they stopped doing it, even if they added money, they were not willing to continue to work, so the two youngest students became "porters", and Tang Chizhou also wanted to share a little time, but the professor and the two students resolutely refused, saying that Tang Chizhou could come with them, and they felt grateful. It's hard to make him carry things.

After Tang Chizhou's repeated insistence, the professor agreed to let him carry it a little lighter, but even so, after Tang Chizhou walked in the mountains for a day, he felt his limbs sore and very tired. Looking at the two students who carried the heaviest things, and the professor, who was no less than him, and was no less old, I didn't notice how tired they were. Tang Chizhou suddenly thought that when he was studying in the United States, a professor once said to him: Westerners have good endurance and can travel with heavy loads for a long time, and they are good army soldiers; Asians, on the other hand, are nimble but not as endurant as Westerners, making them good material for scouts. It seems that the professor was quite right.

They finally came to the foot of the mountain, but the four of them did not rush to find the hiding place of the Taoist priest, but spent seven or eight days in the mountain to investigate the terrain and understand the general shape and topography of the mountain.

They also drew a simple topographic map of the mountain with simple measuring instruments. Every night, when the two students were asleep, Tang Chizhou and the professor often looked at the map until late at night, especially Tang Chizhou gradually saw a lot of clues from these topographic maps according to his profound knowledge of the meridians.

This mountain, as expected, has obvious meridians, and the meridians are similar to the meridians of the human body, which is a bit shocking to Tang Chizhou. So how did he discover the meridians of the mountain?

Tang Chizhou believes that the meridians of people are the flow of qi in the body, and in the same way, there is also qi flowing in the mountain, and the route of the circulation of earth qi in the mountain is the meridian of the mountain.

The flow of earth qi is often closely related to the flow of the stream in the mountains, Tang Chizhou will use a section of bamboo in the near the stream, this kind of bamboo is hollow, half on the ground, half in the ground. Half of the bamboo exposed on the ground is stuffed with the ash of a special grass, the ash of this grass is very sensitive to the earth's qi, and only a little earth's qi is surging, then the ash of this grass will be "blown" from the bamboo by the earth's qi, so that Tang Chizhou can quickly find the direction of the earth's qi, and always follow the vine to find the direction of the mountain's meridians.
