He knew how powerful the explosive pack made by Xinxin was, and he also knew that she wanted to improve that thing, but he didn't think that Xinxin could be dangerous.

How could he be so confident that Xinxin could do it? Xinxin is a human being, not a god, so how could he be able to do everything with ease?

She would also be in danger and afraid! It was his arrogance that harmed Xinxin.

Li Xiaochen was immersed in severe self-blame, his eyes kept looking for someone in the smoky room, for fear of seeing the scene that made him so painful.

But he didn't see Xinxin even after he finished watching the whole thing, which made him even sadder.

"Xinxin! Where are you? Come back!"

Li Xiaochen staggered and fell to the ground, grief-stricken, his Xinxin...!

Li Xiaochen thought that Lin Yuxin was killed in the explosion, with not a single body left. He sat on the ground and cried heartbrokenly.

"Ah Chen? Ahem! What are you doing?"

A crisp sound was heard, accompanied by a few coughs.

Li Xiaochen stopped crying, a trace of surprise appeared on his handsome face, and the tears on his face looked so dazzling.

Was it... an illusion? How did he hear Xinxin's voice?

Li Xiaochen was only confused for a moment. He was not a brainless person. He immediately thought that Xinxin was okay and that she had really spoken just now. So he quickly raised his head and looked towards the direction of the voice.

He saw a person squatting in the corner. He was completely black, even his face was black. Only his two eyes were white. They were blinking and looking at him with a puzzled look!

"Xinxin?"

Li Xiaochen took a cautious step forward and spoke carefully.

"Wuwuwu! Ah Chen!! Please help me check if my face is disfigured! I'm almost scared to death!! Wuwuwu!"

When Lin Yuxin saw Li Xiaochen walking towards her, she immediately burst into tears out of grievance.

Tears flowed down his cheeks, mixing with the black and gray on his face, it was simply horrible to look at.

Seeing that Li Xiaochen was so angry, he didn't dare to go forward for a moment, but when he heard Xinxin crying, he felt distressed! He was afraid that she was really hurt.

Finally, Li Xiaochen sighed helplessly, walked forward, helped Lin Yuxin up, held her in his arms, and whispered comforting words, the trembling on his body revealing his fear just now.

"Alright! Stop crying. Your face is not disfigured. I'm fine. Even if it is disfigured, the King will still want it!"

"Ouch! It's disfigured. My face is blurry and it hurts a bit!!!"

Lin Yuxin touched her face and said aggrievedly.

As she touched it, it became even harder to tell which was the nose and which was the mouth.

Just now at the last moment, she thought she had gotten through, so during the last experiment, she deliberately hid far away.

As a result, when the newly upgraded grenade exploded, the whole room was filled with black smoke, and soon it was completely dark. She suddenly couldn't see anything and could only hide in the corner.

She thought her research had failed, but now she seriously suspected that what had just exploded was not a grenade, but a smoke bomb! It was an improved version of the smoke bomb.

Normally smoke bombs have smoke coming out when you pull the ring, but this one has to be ostentatious to go off, it's really a disgrace to the bomb world!!

"Okay, dear, stop crying and follow me!"

Li Xiaochen couldn't bear to see her cry anymore, so he had to coax her, pulled her out the door, walked all the way to the newly appeared river, looked at her, suppressed his smile, and spoke softly:

"If you don't believe me, just check it out for yourself!"

Lin Yuxin, with a dark head, looked at him in confusion. Just as she was about to look down, Zhizhi came over and circled around her excitedly:

“Squeak, squeak, squeak!”

Wow! Woman, you went to dig coal! How come you are so dark! So ugly!

Lin Yu's face changed when he heard this. No, now even if Lin Yuxin's face changed color, no one could tell.

She quickly lowered her head and looked towards the river, only to see that the woman in the river had a black face with only a pair of white eyes.

A pair of eyes flickered, and Lin Yuxin just wanted to open her mouth, but the white-toothed Lin Yuxin couldn't open her eyes.

"Ah!! Who is this person?"

Lin Yuxin screamed in shock, but when she turned around she saw Li Xiaochen with a look on his face, and she knew that the dark person was her!!!

Woohoo! Her image is totally ruined!!!

Lin Yuxin wants to cry but has no tears!!!

Zhizhi also laughed at her mercilessly, which made Lin Yuxin so angry that she wanted to give it space. She thought so and threatened so.

"You stinky bug, you dare to laugh at me, if you laugh at me, I will send you to exile!"

Lin Yuxin was in a bad mood when she came here, and was bullied and ridiculed by a bug. She immediately got angry and stood up and yelled at the bug.

“Squeak!”

Woman, you are angry and embarrassed! !

Zhizhi ran while talking, and disappeared in a short while.

Lin Yuxin was left alone looking at Li Xiaochen with a pitiful look on his face, and then cried:

"Ah Chen, my image is gone! I look so ugly now! I am too embarrassed to see anyone! Wuwuwu!"

"No, the king likes you no matter what you are like. Okay, go take a shower first, and then see if you are injured anywhere! When you come back, there will be another beautiful and charming Regent Princess, Lin Yuxin of Pingning County!"

Li Xiaochen touched her head without feeling disgusted, comforted her, and then urged her to go wash up.

"oh!"

Lin Yuxin nodded aggrievedly, thinking that Li Xiaochen was right. She was not a person who cared about appearance, so Lin Yuxin stopped dawdling and went directly to the hot spring on the mountain.

Li Xiaochen did not follow them. He honestly went to tidy up the dark room.

There's nothing he can do. There's no one here, so he has to do everything himself. But it would be fine if he and Xinxin could live here for the rest of their lives.

Before Li Xiaochen had finished cleaning up, Lin Yuxin came back.

"Xinxin, are you injured?"

Li Xiaochen immediately stopped what he was doing, walked towards Lin Yuxin, asked with concern, and pulled Lin Yuxin around to look at her.

"No, don't worry, I'm fine. This time the grenade didn't seem to have any damage, but it did become a smoke bomb!"

Lin Yuxin smiled and shook her head, having thrown away the negative emotions just now. She now began to happily talk about the results of her work!

"Smoke bombs? What are those?"

Li Xiaochen looked at her in confusion, these things were unfamiliar to him.

"Smoke bombs release a lot of irritating smoke once they are used, which can cause eye pain, blindness, difficulty breathing, and incessant coughing."

"This kind of thing is not as dangerous as an explosive pack, but it is still very practical. I just thought about it. Since the grenade is useless, I will try it more later. Now that the smoke bomb hit the wrong person, I will make a few more, and keep some for self-defense!"

Lin Yuxin smiled and explained to Li Xiaochen the use of smoke bombs.

This was really a pleasant surprise for her. She had felt guilty about using the explosive pack before, but now that the grenade didn't work and it worked as a smoke bomb, it meant that maybe God didn't want her to use those things to kill innocent people.

She thought that she should keep calm and use the smoke bomb first. As for the grenade, she could try it again when she had the chance. Who knows when she might be able to use it?
