Lan Yu has not come to the molecular restaurant for lunch for more than a week, Zisong has gradually faded out of sight, Mengshi's sadness makes the store manager Ye Siyun see it, so he is very understanding to give Mengshi a week's vacation, as a reward for Mengshi's excellent work during this time.

Grateful for her gratitude, she immediately decided to go on a solo trip and spend a week to free herself. But she didn't know where to go, and the next morning, she walked around the long-distance station in Y City with a ten-kilogram backpack on her back and randomly boarded a tourist bus. The car drove from the cement road to the dusty dirt road, and Meng Shi saw four words written on a stone on the side of the road through the car window, "Tea Horse Ancient Road", and suddenly became interested, "Driver, please stop the car." Mengshi chose to park here because she saw that there was a horse ride not far away, and she liked the completely casual travel, which was an elopement that belonged to one person.

The bell rings in the mountains, and the ancient tea horse road seems more silent in today's world of vehicles, and the aroma of tea grass wafting from ancient times has dissipated. With their own feet, the horsemen stepped out of a rugged and stretching ancient tea horse road, leaving the footprints of the ancestors and the imprint of the horse's hooves on the road, telling the history of the thousand autumns, flashing the glory of China. A few old men leading horses in front of them greeted Mengshi warmly, "Little sister, are you riding a horse?" Mengshi hesitated for a moment, and saw that among the more than ten horses behind the old man, there was a brown horse with bright coat snorting and snorting, and the smell of horse manure mixed with hay was choking. The three or two travelers next to him all got on the horses, and Mengshi liked horseback riding very much, and she couldn't wait. After negotiating the price, Meng Shi stared at the tall horse in front of her, feeling a little frightened, worried that she would fall off the horse's body. The old man who led the horse seemed to see through her thoughts, and said to her with a smile: "This horse is very well-behaved, don't be afraid." ”

The old man patiently instructed Mengshi to ride the horse in the correct posture, Mengshi stood in front of the horse's left shoulder, facing the horse's diagonal back, grabbed the reins and the horse's mane with her left hand, kicked the stirrup with her left leg, and jumped on the ground with her right foot, turning her body lightly and getting on the horse. Meng Shi sat lightly on the saddle, straightened her waist, and looked ahead, dressed in light blue denim, wearing a round hat with a cocked brim, like a professional female knight. The old man shouted, "Let's go!" The horse walked away obediently, "clucking".

Mengshi was a little scared at first, and held on to the reins tightly, but then she slowly got used to it, and the brown horse trotted up and down, and she still found it funny, sitting on the back of a high horse, and a cool breeze passed in her ears. When encountering a bump in the road, the horse suddenly jumped upward, and Mengshi's body subconsciously leaned forward, downhill and backwards. Gradually, Mengshi completely mastered the essentials of horseback riding, turning to the left and pulling the reins on the left, and pulling the right one to the right.

After a while, the horse actually stopped, turned its head to nibble on the grass on the side of the road, and Mengshi found that the horse's eyes were as brown as all over the body, and his eyes were like electricity and bright. The horse ate a few bites and continued to run forward, this time about the momentum, spread its four hooves and galloped forward, Mengshi put her two feet on the horse's pedals, clamped the horse's belly with her two legs and shouted, "Drive!" The horse was running so fast that Mengshi felt that her intestines were about to be turned out, so she wanted to stop, so she pulled the reins and shouted, "Phew!" Mengshi took off the stirrup with her right foot, stretched out her right leg and stepped over the horse's hips, and returned the reins to the old man who was leading the horse.

When the scorching sun was in the sky, Mengshi saw a dense forest not far away, so she wanted to go to the shade of the tree to enjoy the shade, and when she got closer, she found that there was a stone monument at the entrance of the forest, and the stone tablet was engraved with four words: "A single tree becomes a forest". Meng Shi raised her head in surprise, and in front of her was an ancient banyan tree, more than 900 years old, and many aerial roots in the middle of the trunk went down the tree, intertwined with each other, and coiled at the roots. On the main branches on the left and right sides, 34 aerial roots of different sizes descend vertically and penetrate into the soil, forming clumps of pillar roots with connected roots, creating a forest landscape with multiple trunks. The banyan tree is more than 50 meters high, the tree width area is more than 2,000 square meters, the tree shape is peculiar, the branches and leaves are luxuriant, the huge crown can be infinitely stretched in all directions, its pillar roots and branches are intertwined, the shape is like a dense jungle, both like a fence, and like a green barrier, it has become a great spectacle, breaking the saying that "a single filament does not become a line, a single tree does not become a forest".
