Twenty-year-old Lin Yi is reborn in a parallel world—a world where tennis is the world's number one sport—with the memories of a fallen professional tennis player from his previous life. He was once an unknown player ranked outside the top 200 in the ATP rankings, never having touched the glory of a Grand Slam; now, he's reduced to the "King of Double Weaknesses," utterly humiliated by Zhang Hao 6-1, 6-0 in the Xinghai University team selection tournament. Before the shame has faded, fate throws a shocking twist: the [Tennis Legend System] is activated! Starting with the legendary [Spin ​​Serve] skill of Echizen Ryoma? But he needs to complete 100 anti-physics serve training sessions?!

When the laws of physics crumble on the court, when "patented aerodynamic technology" becomes a fig leaf for a repressed young man—Lin Yi adjusted his non-existent hat, his racket pointing straight to the sky: "They say this isn't tennis?" "Sorry, this is just my first shot in conquering the world."

"No matter the world, ordinary people without opportunities will forever remain at the bottom, unable to rise!" "Unfortunately, in the cultivation world, I am an ordinary person." "But fortunately, I have a cheat code!" —————— Tong Yuan thought he would forever live a life worse than a beast of burden, but unexpectedly, he obtained the [Myriad Paths Primordial Mirror] as his master! [Heaven Rewards Diligence]: Whatever you do will surely be accomplished; perseverance will eventually lead to fulfillment. [Seize the Dao of Myriad Spirits]: Illuminate the Dao of myriad spirits, seize the Dao of myriad spirits, and forge my own Dao with the Dao of myriad spirits. Cultivator: "You have no spiritual root, you can't cultivate!" Tong Yuan: "It's alright, I have the [Myriad Spirits Seizing the Dao], your spiritual root is my spiritual root!" Cultivator: "You have no talent, you can't learn supernatural powers!" Tong Yuan: "It's alright, I have [Heaven Rewards Diligence], as long as you're willing to work hard, you can learn any supernatural power." Cultivator: ".............." Tong Yuan: "Speaking of which, the [Myriad Dao Primordial Mirror] can reflect the Dao of all spirits, but why is there no reaction when it shines on my wife? Could my wife be fake?" —————— This is the story of an ordinary person who, after obtaining the [Myriad Dao Primordial Mirror] in the cultivation world, starts from his mortal days, absorbing the talents of all races into himself, integrating countless supernatural powers into one, and rising step by step.

[Ding! Congratulations, host, you have bound yourself to the Gourmet System!] Technology and ruthless skills will have no place to hide in your eyes; moderation and small portions will no longer be nightmares; even a simple steamed bun can make the neighbor's kid drool... Sorry, I'll definitely close later tomorrow! Really!

(Initially, only the female lead can see the system; later, the male lead will discover and see it.) The female lead (originally named Mu Xue) is a Chinese woman who loves watching the Detective Conan anime. However, she is accidentally involved in a car accident and loses her life. After being bound to a system, she is reborn in the Detective Conan world and accidentally activates the cheat system, becoming Shinichi Kudo's older sister: Kudo Yuki. The host's bonus is the owner of Poirot Cafe, and her CP is Rei Furuya. Her mission is to become a fellow police officer with Rei Furuya, and after graduation, infiltrate the upper echelons of the Black Organization as an undercover agent to help Rei Furuya destroy the Black Organization and reverse the fate of the five police officers. However, the mission takes a turn for the worse. Kudo Yuki: "System,"

Li Changsheng transmigrated to the cultivation world and obtained the Heavenly Reward System, which guarantees rewards for hard work. Low aptitude? No problem, I'm immortal. While others practice swordsmanship, I farm; while others cultivate in seclusion, I refine pills. The [Spirit Rain Technique], when maxed out, nourishes the soul; the [Fireball Technique], when maxed out, can scorch the heavens and boil the seas. When enemies come knocking, they see the massive army of maxed-out pill refiners, weapon forgers, formation masters, and talisman users behind me and fall into deep thought.

The "Savior Training Manual," which details a life of leisure before encountering a ruthless killer, lists various activities from cooking, washing floors, and dishwashing to studying, running, and fighting. It emphasizes that persistence leads to proficiency, with occasional bursts of magical knowledge and even the acquisition of magical creature attributes upon leveling up. The manual then addresses the question: "Whose savior spends all day mopping and weeding?! Why is my skill still called 'Weeding' even though I can teleport?! Who wants the golden talent of the Exploding Tail Snail's fart?! Can't I just follow the storyline?!" The manual concludes with: "No! ...Four years later, in the Hogwarts Headmaster's office, Dumbledore unearths long-sealed letters. The manual outlines a training schedule: 5:00-5:30 sprint 10 laps around the neighborhood (youthful energy is amazing!) 5:30-6:00 do a handstand on one finger (what does a handstand on one finger even mean!) 6:20-7:00 weeding...

"At 17 years old, with less than two and a half years of training, is it possible to win a Grand Slam?"

"Yes, I suggest you reincarnate!"

"I suggest you just go to your grave. You couldn't even get past the first round of the ITF Hope Tournament qualifiers!"

"I suggest practicing your serve first. Grand Slam players need to hit the ball over the net, so practice 1,000 serves every day!"

"I suggest you work on your physical fitness, since it's a best-of-five series. Try jogging 10 kilometers every day!"

"I suggest you eat a tennis ball..."

"..."

When Jiang Hong lifted the Grand Slam trophy, a reporter interviewed him.

How did you get to where you are now without a coach?

Jiang Hong took the microphone and said with a serious expression, "My cyber coaches are all over the world, how can you say I don't have any coaches!"

Lu Heng transmigrated to a martial arts world and was sent by his family to the Wudang Sect as a menial Daoist apprentice. He thought he would lead a mundane life, but then he awakened a max-level comprehension system. As long as he studied diligently, observed, listened to teachings, practiced martial arts, and sparred, he could gain something. [Diligently listening to the master's teachings triggers max-level comprehension, leading to perfect mastery of the introductory mental cultivation method.] [Diligently listening to Mo Shenggu's explanation of boxing triggers max-level comprehension, leading to perfect mastery of Wudang boxing techniques.] [Diligently studying Daoist secret texts triggers max-level comprehension, leading to perfect mastery of the Nine Yin Manual.] [Diligently observing martial arts demonstrations triggers max-level comprehension, leading to perfect mastery of Wudang sword techniques.] [Diligently watching Wudang martial arts demonstrations triggers max-level comprehension, leading to perfect mastery of Pure Yang Wuji.] [Diligently sparring with fellow disciples triggers max-level comprehension, leading to...] Years later, Zhang Cuishan returned to Wudang from overseas, embarking on the journey of the Heaven Sword and Dragon Saber...

Transmigrating to a cultivation world, Chen Yi became a menial disciple of a cultivation sect, responsible for cultivating the land for the immortals. He was required to submit a fixed amount of spiritual plants each month, or face expulsion. Fortunately, Chen Yi awakened a talent for rewarding cultivation rewards. Growing [Golden Sprout Rice] yielded [Golden Sprout Rice Planting Proficiency +1] and [One Golden Sprout Pill]. Growing [Nourishment Fruit] yielded [Spiritual Plant Growth Acceleration +1] and [One Bottle of Nourishing Bone Forging Paste]. Growing [Azure Spirit Grass] yielded [Spiritual Plant Growth Grade +1] and [One Year of Spring Breeze and Rain Technique Power]... The higher the level of the spiritual plant grown, the richer and higher the grade of the rewards. Years later, as the immortals decayed and the Great Dao collapsed, Chen Yi, wielding a fallen immortal artifact, clad in fallen spiritual treasures, and with a fallen divine pill in his mouth, relied on his cultivation reward talent to achieve eternal immortality, standing at the pinnacle of the world.
