Yae from Genshin Impact is my sister

"Then, Brother Su Bai, could you help Klee buy some materials for making fireworks? Because Captain Jean forbade Blanche from selling Klee materials for making bombs, Klee can't make fireworks." (Blanche is the owner of the Mondstadt General Store. If I hadn't run out of wheat for Timmy, I wouldn't have known there was a General Store in Mondstadt.)

"Oh, it's just a small matter? You can take care of it, Su Bai. Just write down the materials you need, and I'll buy them for you when we go to the Deer Hunter for breakfast later."

Su Bai patted his chest and agreed. Thinking that she could make fireworks again, Ke Li immediately jumped up with joy.

"Yay, thank you, Brother Su Bai."

"Alright, alright, let's go have breakfast first. I don't know what Ying has been busy with these past few days; she went out so early this morning."

Su Bai, who had made a fortune in Mora, wanted to treat Ying to a meal but couldn't find her. Ying and Paimon seemed very tired lately. Every time they came back, they would take a shower and then fall asleep on the bed. Last night, they even fell asleep as soon as their heads hit the pillow. Su Bai didn't know why they were so tired.

Inside the Mondstadt general store, Su Bai stared incredulously at the string of zeros on the bill. He couldn't understand why alchemical materials for making bombs were so expensive; that string of zeros was enough for Xiaogong to make fireworks for a year.

"Boss, you're not trying to raise the price just because I'm a foreigner, are you?"

“Sir, you’re joking. Our materials are always the lowest priced in Mondstadt, and the materials you’ve purchased are all precious alchemical materials, which are quite expensive.”

"Plus, you just said you wanted them all, that's why they're so expensive. How about I give you a partial refund?"

Su Bai was heartbroken. If he had known these materials were so expensive, he shouldn't have said, "Wrap up all the materials on the paper for me. I'll take all of them, however many you have."

Feeling the expectant look in Klee's eyes at the Deer Hunter Restaurant across from the grocery store, Su Bai paid for the Mora with a long face. Well, he hadn't even been rich for a day before he was broke again.

"Never mind, she's just a kid. It's good that she's good at using her hands. These materials should keep Klee entertained for a while."

After carefully storing away the alchemical materials that had left him penniless again, Su Bai called to Keli and prepared to go home. However, Keli grabbed Su Bai's hand and led him in another direction.

"Claire, have we taken the wrong road?"

"No, no, Keli is going to take Su Bai to Keli's house to see the firework tubes that Keli made. After Keli finishes making the fireworks, Keli and Su Bai will set them off together."

Klee dragged him to the outside of a small house. Klee happily took out her key and opened the door. Su Bai, who was picking his teeth, narrowed his eyes and instantly shielded Klee behind him after seeing what was inside the room.

Chapter 49 You call this thing a firework tube?

The cannon barrel in front of him, made of an unknown metal and as tall as a person with a caliber of half a meter, made Su Bai break out in a cold sweat. Even the cannon that Inazuma activated with the Thunder Seed didn't have a caliber as big as this thing. If he were hit by a cannonball, he would be roasted into a fox.

The image of himself turning into a fragile fox flashed through Su Bai's mind, and he couldn't help but shudder. He blamed Qin in his heart. What was wrong with Qin? How could she leave such a dangerous thing here and give the key back to Keli? What if something happened and Keli got hurt?

"What's wrong with Brother Su Bai? Why are you blocking Ke Li?"

Keli peeked out from behind Su Bai and looked around her house. There was nothing strange about it, just a little messy. Why would Su Bai stop her? It was really puzzling.

"Klee, are you sure this is your home and not Mondstadt's armory?"

The unpainted bombs scattered all over the ground, the alchemy table glowing faintly, and the cannon in front of them—these things shouldn't be in a little girl's house at all, right?

"This is Klee's house. Klee was in such a hurry to leave that she forgot to turn off the alchemy table that her mother left behind."

Klee jumped out from behind Su Bai and casually bypassed the bombs on the ground to shut down the alchemy. Su Bai watched with trepidation as Klee weaved through a pile of bombs. If these bombs exploded, the resulting chain reaction would be incredibly powerful. If anything went wrong, Su Bai would teleport away with Klee immediately.

"Brother Su Bai, what are you doing standing at the door? Come in and sit down. Ke Li will make you some tea."

Claire, imitating her mother, picked up a small teapot and tiptoed to grab tea leaves from a small bag, only to find that the tea leaves hadn't been stored properly and had become damp and moldy. Claire stuck out her tongue; it seemed she would have to buy some tea leaves next time, as there wasn't much at home to entertain guests.

"Um, Brother Su Bai, how about I go get you some water?"

"No, no need for that. Klee, you go ahead and do your work. I'll just sit here."

"Okay, then Keli will continue making fireworks. Su Bai can call Keli if you need anything."

Su Bai found a spot without bombs and sat down. Ke Li didn't stand on ceremony with Su Bai either. After taking a small ruler and gesturing at the 'cannon barrel' for a while, she lay down on the ground and started drawing.

Seeing Klee's seriousness, Su Bai had no choice but to keep his doubts to himself. If this thing really was a cannon designed by Klee, then Su Bai felt that he could buy a few from Jean on behalf of Liyue. He didn't believe that anyone would dare to evade taxes and run away after setting this thing up in Liyue Harbor.

Worried about disturbing Keli, Su Bai finally managed to hold back until Keli finished drawing the blueprints, and then he immediately voiced his question.

"Klee, aren't we making fireworks? Why are you measuring this cannon barrel with a ruler?"

"Cannon tube? What's that? It's a firework tube that Klee made. Brother Su Bai, have you forgotten that Klee is going to make the world's biggest firework?"

Keli tilted her head. It was strange that Su Bai would mistake such an obvious firework tube for a cannon. By the way, what is a cannon? Is it some kind of new type of bomb?

Klee had a lot of questions in her little head, while Su Bai was completely confused by Klee's words, "This is a firework tube." He had participated in the Lantern Festival in Liyue before, and the firework tubes used for setting off fireworks at the Lantern Festival were at most about the length of a forearm, and the largest ones were about three-quarters the length of an arm.

Now Klee is telling him that this metal tube that can fit his whole fox inside is a firework tube? If this thing is a firework tube, then what are the firework tubes of Liyue? Just some noisy toy for kids?

"Hey Klee, we don't actually need to make the firework tubes so big. We can make them smaller and still set off fireworks."

"No, no, that won't do. Klee wants to make the world's biggest fireworks. When Mom comes back, she'll definitely praise Klee."

Keli bit her finger and refused Su Bai's suggestion. She was determined to make the biggest firework so that she could surprise her mother when she came back. Her mother would definitely say that Keli was the best.

Since Keli had already said that, Su Bai knew he couldn't persuade the little one. Helpless, for Keli's safety, Su Bai could only keep a close eye on the busy Keli, so that he could save her immediately if she encountered any danger.

As Klee busied herself near the alchemy table, half of the firework ball in her hand was already finished. After watching her for a while, Su Bai felt that he had underestimated this little girl Klee, both in terms of her alchemical skills and her courage.

So many of the flammable and explosive materials that Blanche mentioned looked like a pile of mud in Klee's hands, showing no sign of any risk of explosion. If Su Bai hadn't seen these particularly explosive materials at Xiaogong's house, he would have wanted to try them out himself.

As for being daring, Klee dared to stuff all the alchemical materials Su Bai bought into a firework ball using an alchemy table. Isn't that daring? Su Bai's intuition told him that if this thing exploded, the entire street might be reduced to ruins.

Just as Su Bai was anxiously watching Klee, ready to intervene at any moment to save her, inside the Dawn Winery, Jean, Diluc, Wendy, and Luminous were chatting and laughing about where to summon Dvalin.

These past few days, all the high-ranking members of the Knights of Favonius have been assassinated by a mysterious figure, and Jean has taken all the power of the Knights of Favonius into her own hands. She must be very tired these days, but for Mondstadt, Jean still shouldered this heavy burden. Jean, who has been working overtime for several days in a row, looks quite haggard. Paimon and Luminous are very concerned and tell Jean to take care of herself and get some rest.

"Let's go to Cape Oath. It's usually not crowded there, so it's a nice place."

After discussing among themselves, the four decided to use Cape Oath, a place that was usually deserted. As for Paimon's suggestion to use the emergency food to summon Dvalin at Dawn Winery, everyone selectively ignored it. If Dvalin went berserk and destroyed Dawn Winery, Mondstadt's tax revenue would be greatly reduced, since Dawn Winery was a major taxpayer in Mondstadt.

Whether it was because Su Bai was watching her the whole time that Klee's desire to perform was activated, she assembled the other half of the firework ball in just one hour.

"Yay, it's almost finished."

"Now we can set off fireworks!"

Ignoring the patches of black and white on her face, Keli held up a round, dark 'ball' and shared her creation with Su Bai. Su Bai had no interest in listening to what Keli was saying; his entire focus was on the 'ball' in Keli's hands.

Seeing Klee playing with the 'ball' in her hand, Su Bai's two tails bristled. He silently circulated his fairy power with trepidation. If this thing really exploded, it would be a question whether he could get Klee out of the blast radius with the little fairy power he had left.

"Hey Klee, how about I teach you a new technique for setting off fireworks?"

"A new technique?"

"Yes, a new technique. They say fireworks look more beautiful when launched at an angle."

Keli was a little confused as to why fireworks looked prettier when set off at an angle. She noticed that other children set off their fireworks vertically. Despite her doubts, Keli nodded in agreement with Su Bai's explanation out of trust in him.

Su Bai wiped the cold sweat from his forehead. Luckily, he had managed to fool Klee. If this thing had been placed upright and pointed towards the sky, and hadn't exploded in the air but instead exploded on the ground, he might have become a wanted criminal in Mondstadt. Klee might even have been labeled an accomplice. Although the food in the solitary confinement cell was delicious, he longed for freedom even more.

Chapter 50 Target Oath Cape

"Brother Su Bai, which direction should we set off the fireworks?"

Keli and Su Bai pushed the firework tube outside. Keli's little head was in trouble again. Because she had only made one firework ball, she could only see the fireworks from one direction. For a moment, Keli was having a hard time making a choice.

"Kelly, think about it, is there any place with few people that also has special meaning for you?"

"Few people? Special significance?"

"Why do we need fewer people, Brother Su Bai? Ke Li wants many people to see the fireworks she made. They are the best fireworks ever."

Klee tilted her head. She didn't yet have a clear understanding of the power of the firework she had made. Su Bai was stumped by Klee's question. He couldn't very well say that he was worried Klee would blow up Mondstadt, that would be too hurtful to Klee.

Just then, a patient with a leg injury and using crutches passed by. Su Bai had a flash of inspiration and knew how to persuade, no, how to convince Ke Li.

"Last time, Klee said she injured Bennett while researching the bomb to blow up the Wraith Dragon. This time, she chose a quiet place to set off fireworks to avoid Bennett. Klee doesn't want to see Bennett get hurt again, right?"

"Okay, Bennett has indeed been injured by Klee's fireworks many times. So let's set off the fireworks in the direction where there are fewer people this time."

Klee thought about it for a moment. Bennett had indeed been injured by her fireworks quite a few times over the years. Worried that Bennett would get hurt again, the kind-hearted girl immediately agreed to set off fireworks in a less crowded place. Su Bai also breathed a sigh of relief. Fortunately, Klee was easy to fool.

"Then let's launch it towards Cape Oath, Brother Su Bai. There aren't many people there during the day."

"And Mom once said she wanted to blow up Cape Oath, maybe Klee will help her realize that idea this time." (The Teyvat Guide mentions that Iris wanted to blow up Cape Oath because she thought the pointed end of Cape Oath was too abrupt, but luckily Kaeya discovered and stopped her. By the way, the Teyvat Guide was written by Iris.)

"Okay, as long as it's a place with hardly anyone around."

Su Bai no longer hoped that the 'fireworks' wouldn't change the terrain of Mondstadt. He just hoped the Rock King would protect him and not hurt anyone. Wait, now that he was in Mondstadt, shouldn't he ask Barbatos for protection? Thinking of Barbatos's irresponsible attitude, Su Bai sighed and decided to continue praying for the Rock King's protection.

"Then let's get ready to set off fireworks, Brother Su Bai. When Mom comes back, Ke Li wants to set off these fireworks with her again."

It seems Klee has truly inherited her mother's talent. I wonder if, when Klee's mother returns, the two of them, one big and one small, will make it impossible to see a single mountain in Mondstadt. Wouldn't Mondstadt then become a plains nation?

Oh, wait, there's another possibility. Maybe the entire Mondstadt region, except for Mondstadt City, will be blasted into a crater by this mother and daughter. In that case, would Mondstadt be considered a basin country? That's a real question.

Just as Su Bai was lost in thought, Klee jumped up and threw the firework ball into the thick firework tube. Perhaps it was a habit he had developed from often setting off fireworks with Ayaka at the Inazuma Festival, but Su Bai subconsciously took out a match from the space of the Eye of God and handed it to Klee.

Keli took the match in a daze. Her firework tube wasn't lit with matches, so why would Brother Su Bai hand her a match?

"Brother Su Bai, Brother Su Bai, after Klee is channeling the fire element, you can use the lightning element to shock the firework tube."

“Claire didn’t make a fuse. Mom said anything with a fuse is unsafe.”

Su Bai then realized that he wasn't in Inazuma. He put the matches away with a sense of loss. Two years had passed since he last saw them. He wondered how his Inazuma friends were doing.

"Brother Su Bai, are you ready?"

"Ready? Klee, let's begin."

Su Bai shook his head to clear his mind of distractions. Now was not the time to think about such things. If he messed up, it would be troublesome if this thing exploded in front of him.

After receiving Su Bai's affirmative answer, Klee placed her small hand on the firework tube. Fire element flowed continuously into the firework tube through Klee's hand, and red light began to emerge from inside the firework tube.

"Brother Su Bai, quick, use lightning to shock him."

Upon hearing Klee's command, Su Bai unhesitatingly gathered a wisp of lightning element and struck the firework tube. Instantly, a violent overload reaction was triggered inside the firework tube. Su Bai only felt a flash of red light before his eyes, and the firework ball had already flown out.

"Brother Su Bai, let's go to the rooftop. We can see very far from there."

Keli eagerly pulled Su Bai and ran to the rooftop. This was a firework she had put a lot of effort into completing, and she was determined to see it explode with her own eyes.

On Cape Oath, Wendy played a beautiful song on the Sky Harp that Luminous had repaired after traveling to countless places. The melodious music almost made Jean, who had been working hard for many days, close her eyes and fall asleep.

The hurricane struck, and the sudden surge of wind element instantly brought Jean back to her senses. When she opened her eyes again, the Stormterror—no, Dvalin—was already standing in front of her.

"I just hope nothing else goes wrong. Mondstadt has been carrying too much of a burden lately..."

Mondstadt's internal troubles have been largely resolved. Once the external threat of Dvalin is eliminated, Mondstadt will usher in a period of unparalleled peace. As the acting captain, she has lived up to the trust placed in her by Captain Falgar and the people of Mondstadt.

“There’s nothing left for us to talk about, Barbatos.”

"Really? Am I seeing things? Dvalin, your eyes seem to be recalling this piece."

Wendy and Dvalin gazed at each other deeply. Although Jean already knew Wendy's identity, witnessing Wendy and Dvalin's interaction still shocked her beyond measure.
