Seeing Ruan Qiao's bitter face, Ji Rong smiled, his smile was very shallow, and even Ruan Qiao didn't notice it.

Looking sideways at the already cracked walls around him, Ji Rong lowered his eyelids, and there was a certain complicated look in his dark eyes.

Yu Guang looked at Ruan Qiao, and seeing that she gradually returned to her usual appearance, Ji Rong suddenly whispered again, "...... I won't let you go. ”

Ruan Qiao, whose smile gradually faded: "......"

So what do you want to do, big brother, to give a clear word?

Ruan Qiao continued to have a bitter face, and walked listlessly with his head down.

"Chief!"

Just as they entered the hallway and were about to go upstairs, a guard suddenly ran over and said to Ji Rong breathlessly, "The monster is attacking again!" ”

How long has it been?

Ji Rong frowned, and subconsciously looked at Ruan Qiao, "I'll let someone take you to Xu Chengan first." ”

Without waiting for Ruan Qiao to reply, he turned around and quickly followed the guard, leaving not even a superfluous word for her.

Ruan Qiao looked at Ji Rong's back in a daze, and didn't react for a while.

Has this guy changed sex, just leave?

Shaking his head and shaking off the inexplicable thoughts in his head, Ruan Qiao only felt that Ji Rong couldn't be more kind like this, and she really couldn't bear the pervert of hugging her at every turn.

"Will you show me the way?" Looking at the guard beside him, Ruan Qiao asked softly.

"Yes." The guard nodded, consciously leading the way.

Now the remaining guards in the scene basically know the importance of Ruan Qiao to Ji Rong, and no matter how much they spurn the identity of a slave, they have to lead the way at this time.

Xu Chengan was also indiscriminately locked in a cell, but his mood was much more stable than Yu Long's, and his treatment was several times better.

When Ruan Qiao passed, he was holding a bowl to eat, and he was still reading a book in his hand.

The sound of the door being opened attracted him to look over, and when he saw that it was Ruan Qiao, he immediately laughed, and said extremely excitedly, "Ruan Qiao, I'll tell you ......"

Noticing the guards beside Ruan Qiao, he still swallowed the unspoken words sensibly.

"You go out first." Ruan Qiao glanced at the guards and walked to the door to close the door.

The guard didn't want to stay here any longer, so he strode out and stood at the door guarding Ruan Qiao.

"What's wrong with you? The smile on his face is almost blooming. Only then did he look back at Xu Chengan, and Ruan Qiao asked with a smile.

"My mission progress has changed again!" There was no one else in the room, Xu Chengan also relaxed a lot, he stepped forward and pulled Ruan Qiao to the table, pointed to the newly obtained note, and said, "After getting this note, my task progress is sixty-six percent!" ”

Xu Cheng'an's task is the same as Ruan Qiao's, so there is no difference in the progress of the mission.

"I didn't show you the note to see any progress." Seeing Xu Cheng'an staring at the note, Ruan Qiao couldn't help but sigh, raised his hand and slapped Xu Cheng'an's shoulder, "How about the riddle that you guessed?" ”

"Didn't guess." Xu Cheng'an replied directly.

Ruan Qiao resisted the urge to roll his eyes, walked to the table and picked up the book Xu Cheng'an was reading just now, looked dumbfounded and said, "Iron-making??? ”

She thought he was reading some books that would help with the task, and who knew what kind of iron smelting he was reading? He really thought he was a guard.

"I'm bored with the guards to borrow it, there's only this kind of book here, and I don't want to read any other books." Xu Chengan scratched his head a little embarrassedly, and laughed like a fool.

Seeing that this guy's madness was as good as ever, Ruan Qiao felt that he seemed to understand why this guy couldn't leave this scene for five years.

Speechless to speechless, Ruan Qiao still hasn't forgotten what his purpose is.

She put the book on the table and picked up two pieces of paper to face it, and did not ignore Xu Chengan's casual ask, "What do you see coming?" ”

Seeing Ruan Qiao asking himself, Xu Chengan also analyzed it very seriously, "I found that the ironmaking technology in this scene is not the same as reality. ”

"What's different?" Ruan Qiao silently recited the two sentences on the note in his heart, and still asked subconsciously, not focusing on Xu Chengan.

Xu Chengan flipped through the book with great interest, "I have never practiced iron in the real world, but I also know that iron smelting probably requires raw materials such as iron ore. But the iron tools of this scene are made of sand and trees. ”

"......" Ruan Qiao raised his eyebrows and looked at it with some interest, "Sand and trees?" ”

You can also make iron with both things.

Xu Chengan pointed to the place where the raw materials were written on the tree, touched his chin and explained seriously, "The sand is the sand of the iron factory, it is said that it contains iron, and the tree is a branch of the tree of life." ”

Speaking of this, he paused, scratched his head in confusion, and said, "But what is the Tree of Life?" ”

Speaking of this, Ruan Qiao once again lost his desire to listen to his words, and looked away to continue to observe the note in his hand, "Haven't you seen it?" You've been in this scene for five years. ”

Xu Chengan coughed a little embarrassed, and felt that it was not appropriate to say this kind of thing at this time, so he put down the book and walked to Ruan Qiao's side and said, "I've heard of it, I heard that there are three colors of fruit in the tree of life, and each color of fruit corresponds to a kind of person." ”

With that, he quickly diverted the topic and said, "Do you see the answer to the mystery?" ”

Ruan Qiao didn't say anything, staring at the note intently, frowning slightly.

"A chance encounter on the front line, ploughing the wasteland together?" She muttered, "Weapons are needed on the battlefield, farming tools are needed to plow the fields, and these are iron tools. ”

Hearing what Ruan Qiao was talking to himself, Xu Chengan immediately nodded in agreement, hurriedly turned the book to the pages of farm tools and weapons, and swept it over with no purpose, "Yes, but is there anything to pay attention to?" ”

Ignoring this idiot question, Ruan Qiao pulled out a chair and sat down, put the piece of paper on the table and continued to look at it.

originally thought that Xu Chengan would pass the two scenes no matter how good he was, and he was more experienced than her in solving this kind of puzzle, but now it seems that he really overestimated him.

While thinking about it, his eyes fell on the page of Xu Cheng'an's spread out, looking at the raw materials of the iron on it, Ruan Qiao's gaze suddenly froze, and his pupils narrowed slightly, "Wait, you said before that most of the mysteries are actually not too difficult, but we can't think of them, right?" ”

Xu Chengan nodded hurriedly.

Ruan Qiao picked up the book and swept his eyes, propped his chin and thought seriously, "The raw materials of ironmaking are sand and the tree of life, not to mention that there is iron in the sand, but it is the first time I have heard of it when I practice with the branches of the tree of life. ”

"There's something wrong with this tree of life?" Xu Chengan asked with a dull face.

Ruan Qiao's eyebrows gradually stretched, and he closed his eyes and leaned back in the chair.

She seemed to know what the mystery was.
