In ancient times, when the heaven and the earth had just separated, the Chinese land was staggering forward in the intertwining of ignorance and prosperity. At that time, Huangdi ascended the throne and shouldered the heavy responsibility of leading the people to prosperity. However, the vision of this peaceful and prosperous era was like a lonely boat tossing in the violent storm. The surrounding enemy states were eyeing covetously, like dark clouds hanging over the newly born country. The haze of war constantly threatened the peace and tranquility of this land.

Huangdi was deeply worried and couldn't sleep day and night, racking his brains for strategies to protect the country and the people. He knew well that human strength was limited, and relying solely on conventional strategies and conquests might not be able to completely resolve these numerous crises. In that era when people held great reverence for the gods of heaven and earth, Huangdi heard that on the distant Kongtong Mountain, there lived a renowned and mysterious Taoist master, Guangchengzi. This Taoist's whereabouts were elusive, but he seemed to have a profound understanding of the mysteries of heaven and earth, possessing extraordinary wisdom and inscrutable Taoist magic, which could help people break free from difficulties and reverse the situation.

Huangdi made up his mind and resolutely embarked on the journey to visit Guangchengzi, regardless of the hardships of the road. He led an elite team of attendants, traversed the vast wilderness, climbed over numerous mountains, and after several months, finally arrived at the foot of Kongtong Mountain. Looking up, the Kongtong Mountain towered into the clouds, with clouds and mists lingering around it, looking like a fairyland and exuding an air of mystery and majesty, which made people couldn't help but feel in awe.

Climbing along the winding mountain path, Huangdi and his party finally found Guangchengzi's residence in a secluded valley. It was a simple and crude thatched cottage, surrounded by green bamboos, with a clear spring gurgling nearby, and a faint fragrance filling the air, like a pure land outside the mortal world. Huangdi straightened his clothes, with a pious heart, and gently knocked on the wooden door of the cottage.

Before long, the thatched door slowly opened, and a white-haired but hale and hearty old man appeared in front of everyone. His eyes were as deep as an abyss, as if he could see through the vanity and essence of all things in the world. This man was none other than Guangchengzi. Seeing this, Huangdi hurriedly stepped forward, bowed and saluted, and told him his worries and expectations one by one.

Guangchengzi nodded slightly, a faint smile on his face, as if he had already known Huangdi's intention. He gently raised his hand, gesturing for Huangdi and the others to enter the house. The furnishings inside the house were simple, with only a table, a couch, and several volumes of Taoist scriptures, but it exuded a quiet and solemn atmosphere. Guangchengzi asked Huangdi to sit down, and then slowly said, "Your Majesty, you have the whole world in your heart and worry about the country and the people. This is the blessing of the common people. However, all things in this world follow the law of heaven. The invasion of enemy states is also a test of the national fortune. To protect the country and the people, one needs to conform to the will of heaven and borrow the power of heaven and earth." After saying that, Guangchengzi turned around and took out a gleaming "Talisman to Protect the Country" from an ancient wooden box in the house.

This talisman was about the size of a palm, with a texture as smooth and warm as jade, yet it also had a toughness like metal. On the talisman's body, there were Five Thunder Talismans drawn. The talismans seemed like living creatures, flashing with faint blue thunder light, faintly emitting a menacing pressure. Holding the talisman, Guangchengzi said solemnly, "This talisman was condensed by me with my lifelong cultivation, combined with the spiritual energy of heaven and earth. The Five Thunder Talismans drawn on it are symbols of the mandate of heaven and heavenly might. Your Majesty, wearing this talisman is like being under the protection of heaven and earth, which can deter the enemy states on all sides, ensure the peace of the land, and make the people live in harmony."

Huangdi took the talisman and immediately felt a warm current flowing into his body along his palm, instantly dispelling his exhaustion and anxiety of many days, and a surge of inexplicable confidence and strength welled up in his heart. He knew the preciousness of this talisman and immediately thanked Guangchengzi again and again, with sincere words, showing his great respect.

With Guangchengzi's expectations and this magical talisman, Huangdi set off on his return journey. Along the way, he seemed to feel the power of heaven and earth merging with himself, and his state of mind became more and more calm and firm. After returning to the capital, Huangdi followed Guangchengzi's instructions and wore the talisman every day when he went to court to handle state affairs. Strangely enough, since then, the enemy troops that had frequently invaded the border seemed to be restrained by some mysterious force and fell into internal chaos one after another, too busy to take care of themselves and having no spare energy to invade the Chinese land. At home, the weather was favorable, the grains were plentiful, and the people lived and worked in peace and contentment, presenting a harmonious and happy scene.

Seeing this situation, Huangdi's respect for Taoism grew even deeper. He knew well that without Guangchengzi's help and the profound wisdom of Taoism, it would have been difficult to achieve this prosperous and peaceful situation so easily. Therefore, Huangdi ordered the construction of magnificent Taoist temples in the capital for Taoist priests to practice and preach. He also regularly went to the temples to worship the gods of heaven and earth, praying for the blessing of the common people.

As for Guangchengzi, this reclusive and eminent Taoist, because he had helped Huangdi achieve extraordinary feats, was invited into the court by Huangdi and respected as a distinguished advisor. Whenever the country faced major decisions, Huangdi would always consult Guangchengzi. Guangchengzi would use his profound Taoist thoughts, combined with the current situation of heaven and earth, to give Huangdi guidance. Under Guangchengzi's assistance, Huangdi implemented the policy of governing by non-interference, allowing the people to recuperate and multiply. The Chinese land ushered in an unprecedented prosperity, laying a solid foundation for the development of civilization in the following thousands of years.

As time passed, the story of Huangdi's quest for talismans to protect the country and the people was passed down from generation to generation on the Chinese land, becoming a glorious legend in the history of the development of Taoism. It not only witnessed the great contributions of Taoist wisdom in troubled times but also made later generations have a deeper respect and contemplation for the mysterious Taoist magic and the Taoist concepts of conforming to the will of heaven and protecting the country and the people. It was like a bright lamp, illuminating the long journey of the Chinese civilization. Even today, when people mention this ancient legend, they can still feel the shock and inspiration coming from across time and space, inspiring generations of Chinese descendants to pursue the right path of heaven and earth and safeguard the peace of the homeland.
