Princess Consort Is No Pushover

"This is just a room for storing sundries. It has been locked all the time. My mother never let us get close before. I suspect there is really something wrong with it." Yun Ruoyue said.

Ling'er nodded in agreement, "Well, but we don't have a key, so we can't open this lock, what should we do?"

"I have a solution." Yun Ruoyue took a bottle of magic acid from the medical system as soon as she finished speaking.

This magic acid, like aqua regia, can corrode things.

But its effect is a hundred times that of aqua regia.

It is a chemical substance. They used it when they were researching medicines, so they are also available in the hospital.

This magic acid is a highly corrosive solution. When its concentration is particularly strong, it will be very corrosive. It can corrode any material such as gold, silver, iron, etc., but it only reacts to alloy compounds and has no reaction to proteins.

In other words, this magic acid can corrode spoons, iron locks and other things, but it will not corrode the flesh and will not harm the human body.

Therefore, Yun Ruoyue took out a small bottle of magic acid from the cold storage of the medical system with confidence.

When Ling'er and Jiu'er saw the bottle of magic acid, they both looked puzzled, "Sister, what is this thing? Why haven't I seen it before?"

"This is magic acid. It's a potion that I developed to corrode gold, silver and iron. Look at it." After Yun Ruoyue finished speaking, she opened the magic acid and poured a little on the handle of the iron lock. In an instant, the lock handle was slowly corroded.

In less than twenty seconds, the handle of the lock was corroded and broken. Yun Ruoyue pulled the lock with her hand, and the lock came off.

Seeing this scene, Ling'er and Jiu'er were surprised.

"Sister, this magic acid is too powerful. You are so powerful. You broke the lock in one fell swoop. Come on, let's go in and have a look." Ling'er said.

Yun Ruoyue nodded, threw the lock on the ground, then gently opened the door and looked into the room.

But after she opened the door, she only saw tables and benches with broken legs and some old furniture piled up in the room. The inside was full of dust, and there were cobwebs everywhere in the corners. It seemed that the room was unoccupied. utility room.

Ling'er and Jiu'er also came over, and they were also taken aback when they saw these sundries.

"Eldest sister, why is there nothing but sundries in here? But I really heard the sound last time. Could it be that the ghost will come out at night?" Ling'er said with a terrified expression.

At this moment, there was an anxious knock on the door from the opposite wall, followed by a very panicked cry. The cry was indistinct, babbling, and it sounded like a female voice.

In the sound of knocking on the door, there was also the sound of chains colliding, the sound was clattering, and there was a cold echo, which was very scary.

Ling'er was so frightened that she hugged Yun Ruoyue tightly, "Sister, did you hear that? That's the sound, it's so scary, where did it come from, there are no ghosts in broad daylight, right?"

Yun Ruoyue was also taken aback by the sound. She realized that the sound was coming from the opposite wall, so she clenched the stick tightly in her hand, boldly walked towards the wall step by step.

As she walked, she boldly asked, "Who's in there? Is it a person or is someone pretending to be a ghost? Get out!"

She really doesn't believe there are ghosts in this world.

Who knew that as soon as she finished speaking, the sound of knocking on the door became more urgent and harsher, like a reminder.

The sound of knocking on the door and the clanging of chains made their hair stand on end.
