After getting the key to the 'World Gate', Venti did not use it in Mondstadt but instead went to the 'God's Domain'. The environment here was exactly the same as Mondstadt, essentially a smaller version of the city.
Takumi looked at Jean and said seriously, "Jean Gunnhildr."
Jean quickly lowered her head respectfully.
Takumi continued, "You are very kind. I hope you will not tolerate the existence of evil people and will not give them time to correct themselves. You must remember that delayed justice is not true justice. The same goes for good and evil. Delayed kindness is merely atonement for previous evils."
Jean said firmly, "Yes, Lord Tianli, I will remember your words." What the god, who was even greater than Lord Barbatos, said must be true. After witnessing the decline of human nature in the two apocalyptic worlds, she understood better that extraordinary measures must be taken in extraordinary times. Mondstadt and those two worlds were completely different places. Her approach worked for Mondstadt, but it might not be suitable for such worlds.
Alice put her hands on her hips. "Jean, it's actually very simple. Just ask the God of Wind to give you some divine power, and then you can distinguish between good and evil."
Venti nodded. "I also thought of that." He clapped his hands, and a green light of divine power appeared before him. A one-handed sword formed in the light.
The blade seemed to be made of blue glass, emitting a faint glow. The hilt was platinum, inlaid with the same glowing sapphire, making it look incredibly gorgeous and sacred.
"This is the Sky Blade. It was made from Dvalin's fallen teeth. It carries my divine power and blessing. It can be regarded as an artifact. I have imbued this sword with the power to distinguish between good and evil according to Lord Tianli's will. If it detects an evil person, the blade will be surrounded by the wind, and the sword will execute the one it entangles."
Jean stretched out her hand, holding the 'Sky Blade' with a serious expression. "Thank you, Lord Barbatos. I will not let you down."
Venti threw the golden key in his hand, saying, "Then, let the mission to save the world begin."
Jean also threw her golden key.
The golden key emitted a dazzling light, which continued to expand until a huge golden portal, over a hundred meters in height, appeared. A powerful 'supreme power' enveloped Venti.
Venti knew that this 'supreme power' would carry his words into the two different worlds. This 'miracle' would play an important role in influencing the people in those apocalyptic worlds, completing half of his mission.
Venti spoke softly:
"[People in the last days, hear my words of wisdom. Standing in the sun makes you a hero, while standing in the shade can also bring disaster. The same is true of courage. Those who have had a smooth journey may not understand its true value. But in times of despair, courage is the only light that allows you to fight back and rise from the darkness. My name is Barbatos, the God of Breeze and Hope under the Heavenly Law. I bring hope to the kind-hearted even in the apocalypse. God loves humanity, but not with unconditional love. Hope and freedom do not come to evildoers. Innocence and kindness are treasures loved by the Heavenly Law—embrace them tightly. Embrace kindness and innocence; use courage as a weapon, and hope and redemption will come to you.]"
The voice of Venti filled with divine grace descended into the two apocalyptic worlds through the 'Supreme Power'.

**Highschool of the Dead World**
At that time, the 'Dead Body Virus' was silently spreading through the entire island nation. People inhaled the virus in the air as they went about their daily lives—working, studying, or driving. Those with weaker immune systems became infected almost instantly, transforming into the undead.
In less than a minute, the entire city was paralyzed. The number of infected people and deaths reached almost 30% of the country's population in a flash. The undead began attacking and biting the remaining uninfected citizens.
Screams, vehicle collisions, and explosions resounded throughout every city.
In less than two hours, half of the population in every city had been turned into undead, attacking those who desperately tried to flee.
"Ahhh! It hurts! What is happening?!" screamed a man as an undead bit into his arm.
"Help! Don't leave me here! Get this thing off me!" another person cried as they struggled against an undead.
"What is going on?! It's like something out of a zombie movie!"
People were fleeing, crashing their vehicles as smoke rose throughout the city—as if a world war had begun.
**Fujimi Academy**
A small number of students had already succumbed to the 'Dead Body Virus,' transforming into undead and attacking those around them. The academy was filled with screams.
"Close the door! Quick!" someone yelled.
The closed school quickly became a death trap, especially for those on the higher floors. If they wanted to escape, they would have to face the horde of undead on the ground.
A group of students who had managed to reach the rooftop and barricade the door with heavy objects were in a state of panic.
A blonde girl in a sailor school uniform was crying. "W-What should we do?! Why is this happening?! It's like we're in a horror movie!"
Another girl with pink twin-tails, also in a sailor suit, hugged herself and shivered. "Who knows what's happening? We're trapped! Everyone's turning into zombies!"
A dozen or so students who had survived and escaped to the rooftop were shouting and crying in fear.
"Is this the end of the world?"
"We were just in class! Why did everything suddenly turn into this nightmare?!"
Amidst the chaos, a girl with long hair, sharp eyes, and a wooden sword used for kendo practice spoke up, trying to remain calm.
"Everyone, please calm down. Those infected respond to sound, and if we keep screaming, more of them will come, and we'll be trapped here forever."
