"Master, are we going out now?" asked Su Ruoxi softly.

Hearing the words, Su Ruoxi looked around and asked, "Look again, this place is really strange, and if it's just the brocade box just now, and the letters in the brocade box, it shouldn't be a treasure, right? Soft, are you sure? There's no other baby here?"

"Without the master, the thing with strong spiritual power that I can feel is the brocade box that you just put away, and the rest is nothing special!" Ruan Ruan heard the words and carefully sensed it again.

"That's weird. Those people outside will not talk about it. Is there such an open space behind this maze, is it just to hide a letter?" Su Ruoxi frowned.

"It shouldn't be, there is something to hide in a letter, is it a secret letter or a treasure map?" Ruan Ruoxi looked at Su Ruoxi after thinking softly and asked.

"Treasure map? It's possible. It looks like we need to study the brocade box and letter!" Su Ruoxi said with bright eyes.

So she looked around and determined that there was nothing special, Su Ruoxi directly took out a cushion and placed it on the grass, and then took out the brocade box and the letter in the brocade box together!

Su Ruoxi put the brocade box on the ground, first opened the letter without text, and decided to study it carefully. Since it was stored in the brocade box, there is no reason for it to be a piece of paper. , at least it should be a sealed letter!

Su Ruoxi tried wiping it with water and roasting it with fire, but none of the letters or patterns could be displayed on the letter paper. In the end, Su Ruoxi thought that there seems to be some kind of potion that is also used to hide the words...

Although Su Ruoxi is not sure if it is useful, but Su Ruoxi is an alchemist!

After a careful search of the medicinal materials in her mind and the memory of her previous life, she found a way. Soon Su Ruoxi extracted a bottle of potion and wiped the letter paper directly with the potion, but it still didn't work, there was nothing...

"Master, all you wipe is the edge of the letter, maybe the text is in the middle?" Ruan Ruan looked at it and thought about it.

Su Ruoxi heard the words and thought it made sense, so she tried to wipe the potion in the middle, but there was still nothing!

Su Ruoxi touched her chin, frowned and stared at the slowly drying, blank stationery, a little depressed!

"Master, you may try some juice from the leaves of the holy fruit. I remember that the leaves of the holy fruit have the effect of purifying all hidden traces. It seems to be especially effective for letters..." At this time, Xiaobai's voice was in Su Ruo. A voice sounded in Xi's mind.

"Really? Then give me a try..." Su Ruoxi said after hearing the words.

Soon Xiaobai carefully gave Su Ruoxi a small porcelain plate, and there were three drops of crystal clear, green juice in it. Each drop was independent, but the three drops together were not as big as Su Ruoxi's little mother's fingernail. ...

Su Ruoxi...

"Xiao Bai, are you too little?" Su Ruoxi asked speechlessly.

Although she also knows that the holy fruit tree is full of treasures, but there is a whole holy fruit tree in the space, why is Xiaobai so stingy!

"Master, there is only such a holy fruit tree in the world. Besides, if such a treasure is used to read letters, it may not be effective. Will your conscience not hurt? I just heard about it, in case it doesn't work. Isn't it a waste! Waste is a shameful master!" Xiao Bai said very seriously.
