After traveling to the continent of Teyvat, Ron received a marriage contract and went to Fontaine to find his fiancée whom he had never met.

Unexpectedly, Navia could hear his thoughts.

"Let me introduce you. This is Myles and this is Silver."

[Of the great baking trio, only Navia is left. Let's cherish the time they are still alive!!]

"Ron, you'll be able to see Uncle Marcelle soon!"

"Uncle Marcelle?! You're such a filial son! Your father was killed by Marcelle, and yet you still call him so affectionately! Yeah, Navia's still been kept in the dark, so it's understandable!"

"Ron, do you think Tartaglia is the real culprit behind the serial disappearances?"

"Are you kidding me? A nineteen-year-old Tartaglia could actually commit a crime twenty years ago? Is this a sign of moral decline or a lack of law?"

Hearing these thoughts, Navia was numb.

"Ron, can't you just say something?"

Holding the other half of the jade pendant tightly in her hand, Navia looked at Ron angrily, hesitating whether to tell Ron the truth that she was the fiancée Ron had been looking for.

[You were born as the son of the humble king Vortigern] [You pulled the sword from the stone, but thrust it back in, the blade emitting a clanging cry] [You promoted farming, popularized education, and abolished the nobility. The knights reviled you as "the son of the ominous white dragon"] [You sacrificed Vortigern, gathered the remaining flames of the last days of the Age of Gods, and launched a final assault on the Inner Sea of ​​Stars]... [Your wife and daughter died at the hands of Ares...] [You took up the demonic sword Aatrox] [You burned the Temple of Olympus]... The wheels of the carriage rolled over...

Lin Fan traveled to the continent of Teyvat and inherited a grocery store in Liyue Harbor at the beginning, intending to just let it run wild and get by.

But one night in a warehouse, he found a blue-haired girl who was unconscious due to overtime work and had a beautiful sleeping face!

[Ding! The Human Fireworks System has been activated! Goal: Let Ganyu sleep peacefully. Reward: God-level talent!]

From then on, his shop became the strongest shelter and holy place for slacking off in Teyvat!

Guests from the Wangsheng Hall come to buy things on credit every day, and they always ask, "Put it on the Wangsheng Hall's account."

The demon-slaying sage Xiao squatted on the roof just for a bite of almond tofu.

Qixing Secretary Gan Yu stayed on his bed and begged for a refill of refreshing flower tea.

The clever Walnut always wants him to book the Wangshengtang set meal in advance!

When the vortex demon attacks, Liyue Harbor is in danger.

Lin Fan hung up a sign that read "Closed Today" and said helplessly to the "ordinary" customers in the store:

"Mr. Zhongli, stop dishing out walnuts. Your (former) subordinates are about to be drowned."

"Ying, stop playing games. It's time to unsheathe your Wuxiang sword."

"And Wendy, stop pretending to be drunk and get up and work!"

He just wanted to be a quiet shop owner, but these big-name customers were all hidden top gods?!

The Liyue immortals may have dabbled in alchemy, but the recipe of the white-haired young man from Aozang Mountain left them all looking at each other in bewilderment...

"Hair from the Great Sage, saliva from the Golden Traveler, powder from the horn of the Ryota Dragon King, a bowl of Paimon soup..."

"It's done! Four-image pill!"

"If you eat it, you'll gain the height of the Great Sage, the resistance of the Traveler, the weight of the Dragon King, and... the appetite of Paimon?"

When the white-haired boy wanted to find someone to test the efficacy of the medicine, the immortals had already hidden away.

Su Chen traveled through the Star Iron World, turned on the live broadcast system, and invited countless film, television, and animation characters to join.

Let's start taking stock of the Myriad World Systems. The first one is the Star Dome Railway:

The embodiment of concepts, the supreme being—Star God!

There is the [Hunting Star God] Lan, who destroys planets with his light arrows, and there is the [Protective Star God] Krippo, who strikes his giant hammer to create a crystal wall that stretches across trillions of light years.

Zero: Such a powerful existence, perhaps only the King of Ultra can rival him.

Lei Movie: Isn’t the justice of heaven enough for them?

Ultra World

There are powerful monsters like Gatanjea, Mog-Orochi, and even Hyperzetton, capable of destroying the universe!

There are also the mysterious Four Os and other powerful combat forces.

Sukuna: Huh? I'm fighting Tiga, is that true?

Muzan: Compared to them, the perfect life I dream of is a joke.

Emperor Yan: This is the real strong man, who can sweep away everything!

"I traveled to Type-Moon and gained the recognition of the Root. As long as I can die an abnormal death, I can ascend to the Throne of Heroes and become the Lord of the Throne of Heroes, an existence that is stronger and freer than the Seven Crowns." "For this reason, I started to act like a fool in Type-Moon." "I scolded Gilgamesh to his face, challenged the almighty Zeus in Greece, openly kidnapped Skadi in Northern Europe, declared that Solomon was a demon god instead of the Son of God in Israel, and stood on Morgan's side in Britain..." "But why am I still alive now?" 1994, Fuyuki. A famous figure in history, the third friend of the Most Ancient King, the first prime minister of Mesopotamia, the man favored by the Greek gods, the king of giants in Northern Europe, the incarnation of God who awakened Solomon's humanity in Israel, assisted by Prince Camelot... The young but weathered-looking Lovi sat on the top of the Fuyuki Bridge, sighed, and looked at the scene in front of him: "Tell me, what went wrong here?" "Or, you kill me and let me ascend to the Throne of Heroes? Please!" Kiritsugu Emiya lit a cigarette, glanced at Artoria who was holding the Holy Spear next to him, the King's Treasure unfolded by Gilgamesh, the red spear tip extended from the Kingdom of Shadows... The hand holding the cigarette trembled slightly.
