Xia Xiwan probably knows why Mommy chose Li Wenqing as an apprentice, Li Wenqing is fraternity in his heart, he is a real doctor, his temperament is simple and free, and he is very suitable for acupuncture to prolong life.

"Dean, did your master leave anything behind in this Privy Council?"

Xia Xiwan went straight to the point, she had been waiting for Dean Li Wenqing to come back, because Aunt Lin said that Mommy had left something for her.

Dean Li Wenqing's face changed, "Xiwan, how did you know about this?" ”

"Someone told me, Dean, can you give me this thing?"

Dean Li Wenqing pondered for a moment, "When my master disappeared, he said that someone would come to pick up this box in the future, although I don't know how you know, but you come with me." ”

It's that easy?

Xia Xiwan really didn't expect that she would get the box left by Mommy so easily.

……

Dean's Office.

Dean Li Changqing opened the safe and took out a small box, "Xiwan, my master left this box in the research institute, but the box has a lock, if you can open the lock, I will let you take the box away, if not, then I'm sorry, I have to take it back." ”

And locks?

Xia Xiwan knew that this matter was not so easy, and Aunt Lin didn't tell her about the lock when she woke up.

Xia Xiwan took a look at the lock of the box, her pupils shrank, this is not an ordinary lock, the lock cylinder is directly embedded in the box, there should be a fine and complex mechanical bearing inside, it is not opened with a key or password at all, it is more similar to the gossip diagram in ancient times.

Xia Xiwan studied for a moment, then took out the silver needle she carried with her, and she pushed the slender silver needle into the keyhole.

Dean Li Wenqing nodded approvingly, "Yes, this box is to be opened with a silver needle, and the way to open it is a set of needles, my master is a fairy-like figure, and the things she left behind are priceless treasures, but whether you can take it away depends on your ability." ”

Xia Xiwan held her breath, when she inserted the first needle, her fingertips already felt the switch inside running, her fingertips lightly picked, and turned the needle method into the trajectory of the mechanical bearing, click, and the first level opened.

Dean Li Changqing applauded, "It is worthy of my favorite apprentice." ”

Xia Xiwan picked up the second needle, and soon after, there was another click, and the second level opened.

"Beautiful!" Dean Li Changqing's eyes lit up.

Xia Xiwan was already sweating, and as the level of breakthrough increased, the stitches contained in it became more and more extensive and mysterious, and she felt struggling.

With a click, the third level opens again.

Dean Li Changqing gave a thumbs up, "Awesome!" ”

Xia Xiwan only felt that her throat was fishy and sweet, and there seemed to be a stream of qi and blood gushing out of her chest, she had studied medicine for so long, and now she felt that she was in a vast ocean, and she was just a drifting duckweed, because she was not strong enough to forcibly open the treasure chest, and she was now surging with blood and blood.

Xia Xiwan sat down on the chair and forcibly suppressed the fishy sweetness in her throat, she waved her hand, "I can't do it, I definitely won't be able to pass the next level, I give up." ”

Dean Li Changqing put the treasure chest back in the safe, and he smiled and said, "Xiwan, you can break through three levels in a row, it really shocks me, it's okay, you can fight again next time!" ”
