Armor Sign-In: Invincible from the Emperor

Lin Yu felt like the world was spinning. When he regained consciousness again, he found himself in a strange street. The surrounding architectural style is somewhat similar to modern times, but it also has a unique film and television texture. "Where is this?" Lin Yu rubbed his head and tried to remember. At this moment, a mechanical voice suddenly sounded in his mind: "Congratulations to the host for traveling to the world of armored warriors, the sign-in system is activated!" "Sign-in system? Armor Warrior World?" Lin Yu was stunned for a moment, and then a burst of ecstasy surged in his heart. As a loyal fan of the Armored Warriors, he is all too familiar with this world. "System, how do I sign in?" Lin Yu asked impatiently. "The host can trigger sign-in at a specific location. After successful sign-in, you will receive various rewards, including but not limited to armor summoners, strengthening potions, skills, etc." The system replied. Lin Yu began to explore around the streets. According to the plot in his memory, he felt that this should be the place where the story of "The Legend of Armor Warriors" takes place. As he walked, he came to a remote alley. "Ding! It has been detected that the host is at a hidden check-in point - an abandoned alley where shadow beasts roam. Do you want to sign in?" The system prompt sounded. "Sign in!" Lin Yu said without hesitation. "Sign in successfully! Congratulations to the host for obtaining the Flame Dragon Armor Summoner (Elementary) and the Flame Dragon Armor's exclusive skill - Demon Sealing Slash proficiency increased by 50%." Lin Yu's hand flashed with light, and a red Flame Dragon Armor Summoner appeared in his hand. Feeling the warmth from the summoner, Lin Yu was very excited. At this moment, there was a burst of sinister laughter from deep in the alley, and a black supernatural beast slowly walked out. This supernatural beast looks like a wolf and exudes an evil aura. "You've come just in time, let me try it with the newly acquired Flame Dragon Armor!" Lin Yu shouted, raised the summoner in front of his chest, and shouted: "Fire Dragon Armor, merge!" A red light flashed, and Lin Yu instantly transformed into the Flame Dragon Armor. Red armor covered the whole body, emitting a blazing light. The supernatural beast roared and rushed over. Lin Yu did not panic, dodged sideways, and then hit the supernatural beast with a flame dragon punch. The supernatural beast felt pain and took a few steps back. "Demon Sealing Slash!" Lin Yu quickly formed seals with his hands, and a long knife burning with flames appeared in his hands. He swung it hard, and a flaming sword energy rushed towards the supernatural beast. The supernatural beast wanted to dodge, but it couldn't keep up with the speed at all. After being hit by the Demon-Sealing Slash, it let out a scream and dissipated into black smoke. "Successfully defeating the supernatural beast will reward you with a bottle of Flame Dragon Armor energy upgrade potion, which can increase the energy level of the Flame Dragon Armor." The system prompt sounded again. Lin Yu released his transformation and looked at the potion in his hand, his heart filled with joy. With the sign-in system, his adventure in this world of armored warriors has officially begun. As time went by, Lin Yu continued to obtain various powerful equipment and skills through the sign-in system. Not only did he upgrade the Flame Dragon Armor to the top level, but he also successively signed in and obtained summoners for the Wind Eagle Armor, Black Rhinoceros Armor, Snow Mastiff Armor, and Earth Tiger Armor. In a fierce battle with the Shadow Emperor, Lin Yu summoned five sets of armor at the same time, and performed the ultimate killing move of five elements in one, completely annihilating the Shadow Emperor in one fell swoop and saving the entire world. Since then, Lin Yu has become a legendary hero in the world of armored warriors, and his signing journey is still continuing... Concept: An ordinary young man is accidentally involved in this battle between good and evil. How he grew from an ordinary person to an armored warrior guarding justice is a story about courage, faith and growth. "
