Huangfu Longdou, capable of traversing countless worlds, relies on a side-effect transfer system to continuously travel and level up. He experiences various worlds: the technological muscle-building abilities of the Kengan world, the spider-like powers causing the death of loved ones, the Green Goblin serum's second personality, the technological serums of Shaolin Soccer, the internal energy conflicts of the Star Absorbing Technique, the internal organ damage of the Seven Injury Fist, the disfigurement and poisoning of the Thousand Spider Poison Hand, the Star Absorbing and body explosion of the Amazing Couple, the Shennong Sect's poisons of The Great Laughing Jianghu, the Crimson Fire Divine Skill of the Storm Riders world, the Lizard Serum of The Amazing Spider-Man, the Devil Fruits of the One Piece world, the God Genes of the Corpse Brother world, the Pure Dharma of Mount Shu, the Fenji Sword with its malevolent energy, the monster cells of the One-Punch Man world, and the Iron Man world...

Xu Yi transmigrated to the world of "Covering the Sky" and became the brother-in-law of the future Emperor Ye, hoping to curry favor with him. Unexpectedly, he also awakened the Flawless Chaos Body and the Ancient Double Pupils, directly becoming the strongest genius of the Golden Age. At this time, the "All Heavens Great Dao Chat Group" invited him to join. Everyone in the group was talented, eloquent, and knowledgeable. Han Li of the Seven Mysteries Sect: "Fellow group members, I, Han, must take a step back, be careful." Ying Zheng: "I just want to become an immortal, that's not too much to ask, is it?" Mischievous Kid: "Come on, come on, let's livestream the ancestor of barbecue, repeatedly deep-fried..." Keisha: "Having devoured so many stars and comprehended so many laws..."

Having transmigrated into the body of a holy son of a sacred land, Lu Qingxuan awakened a word system with no cooldown and no side effects!

I can replicate other people's talents, physique, and opportunities at a glance!

Useless attributes? Instantly merge them into god-tier talents!

[Swordsmanship for Beginners] + [Introduction to Fist Techniques] + [Basic Legwork] = [Martial Arts Master]?

While other holy sons were fighting tooth and nail for a divine body, he had already fused the [Ancient Holy Body] with the [Chaotic Dao Body], forging a unique body for all eternity.

Years later, the Supreme Being of the Immortal Realm was horrified to discover that the unparalleled Dao Fruit he had painstakingly cultivated for millennia had been casually dismantled, merged, and optimized by that "Ancestor of the Dao of Terms"...

Lu Qingxuan: "I'm not targeting anyone in particular. I'm saying that everyone here is part of my database of reference material."

Arrive in Douluo Continent and load the fishing system.

Give me your bloodline!

Give me the elixir!

Give me this amazing artifact!

Give me everything that's mine!

Little Tang San dares to provoke me? I'll wipe them all out!

[I recommend a friend's book; this Douluo Continent novel seems a bit off.]

Ning Su transmigrated to the Dou Qi Continent and became a Devouring Python.

Furthermore, it awakened the 'Infinite Devouring' system, which allows it to become stronger by devouring things.

However, she was unexpectedly discovered by Medusa and taken back to the snake people, where she became Medusa's pet.

Medusa: "Little one, don't you need to devour things to become stronger? Come, see what I've brought you."

Monsters, elixirs, exotic flames... everything is available.

Ning said that living off a woman is indeed delicious.

The Queen's life is even more enjoyable!

...

Many years later.

Medusa: "Ninja, what are you going to do? I am your master..."

Ning said, "Of course I should repay you properly, my Queen."

...

Ye Hao has transmigrated!

However, upon discovering that he had become the Sea Heart Flame in the hands of Han Feng, this traitorous disciple, Ye Hao felt a wave of dizziness and a sense of utter ruin.

Fortunately, there's always a way out, and the golden finger, a standard feature for transmigrators, is activated...

"Hmm... Let's set a small goal first: break through to the Dou Di realm within ten years. Isn't that a bit much?"

Traversing the Swallowed Starry Sky, carrying the Three Thousand Great Daos of Immortality, he swept through the land unchallenged. On Earth: Using the Zerg hive's poison gas to cultivate a supreme poison technique, his cosmic-level attacks were unmatched. In the Universe: The Great Five Elements Technique... the Great World Technique... mastering all the laws. The Great Blood Soul Technique, the Great Devouring Technique... mastering perfect genes. The Great Treasure Refining Technique transformed him into a wholesaler of precious treasures.

He transmigrated to the world of Swallowed Star, becoming Luo Feng's younger brother, Luo Hua. His body underwent a special transformation due to the gourd he carried with him, granting him the abilities of the Calabash Brothers. His seven clones are: First Brother, wielding double axes, a darling of the Earth Law; Second Brother, wielding a bow and arrow, with clairvoyance and keen hearing, a darling of the Wood Law; Third Brother, wielding brass knuckle dusters, a darling of the Metal Law; Fourth Brother, wielding a long staff, controlling fire, a darling of the Fire Law; Fifth Brother, wielding a spear, controlling water, a darling of the Water Law; Sixth Brother, wielding a dagger, becoming invisible, a darling of the Space Law; and Seventh Brother, nurturing gourd seeds, a darling of the Time Law. Each of these seven clones is an extremely powerful being.

Lin Feng transmigrated to the Douluo Continent, only to find himself transformed into a soul beast with no strength whatsoever, except for his cuteness. Fortunately, during a foraging trip, his cuteness earned him a Saintess, Bibi Dong, as his human servant. Having died from overwork in his previous life, and finding the outside world far too dangerous, Lin Feng, after awakening the "Idle Fish Sign-in System," became increasingly lazy and irresponsible each day! Who would have thought that Bibi Dong could hear Lin Feng's thoughts? "Little Fengfeng, give me a hug!" [A little tighter, hug me tighter!] "Little Fengfeng, a maid brought over a bowl of soup. Do you want to drink it together? After we finish, we'll go see our teacher!" [Shapi, what are you drinking? That's a sleeping potion! If you drink it, you'll be waiting to be... you know... done to you by your beastly teacher!]... Bibi Dong: "Little Fengfeng, you're truly a lucky star for our Spirit Hall!"

Lu Yuan transmigrated to a cultivation world and awakened a system with only one function.

That's copy and paste, and from then on, I embarked on an invincible path!

"Copy cultivation level!"

"Not enough immortal artifacts? Just batch copy them!"

"Only one elixir? Copy it!"

"Copy, copy, copy... paste, paste, paste!"

"......"

Everything can be copied!
