"Besides, it's not so easy to catch him, and letting him go doesn't let him go." What Feng Jinyi said, everyone was in a trance, what to let go is not really let go, what Feng Jinyi said is profound.

"Hehe, I know you don't understand, you look at the ground?" Zuo Tingxue motioned for everyone to look at the ground.

"Huh?" Jin Tao was surprised and looked at the clear footprints on the ground and some black sand on the white plaster, this looks particularly conspicuous, when did this happen?

"What is this?" Su Zhe opened his round eyes wide and pointed at the black sand on the ground, and his tangled expression was one head or two.

"It was left by the murderer, and now I understand that what I just said about letting it go means not letting it go." Feng Jinyi said, opened the black satin in his hand, and the silver needles tied in it were all shining, Feng Jinyi pulled out the silver needles one by one elegantly, and put them in the moonlight, flashing with silver brilliance.

"You scrape the black sand off carefully now, and be careful not to destroy the footprints." Zuo listened to Xue commanded.

Su Zhehao took action without hesitation, speaking of which, Su Zhe looked thin and relished on weekdays, and he was unambiguous when he started to do things, and he packed all the black sand into a cloth bag in a few kung fung. There were two clear footprints left on the ground.

Zuo Tingxue looked at the two footprints, squinted her eyes, looked at them carefully, and kept them firmly in mind.

It was already the second watch day when she returned to Shunlin Palace, Zuo Tingxue told everyone to go down and rest, and then she took out the pen, ink and paper she had prepared before and put it on the table, and after a moment of silence, she drew silently, and when she put down the pen and stared at the things drawn on the paper, she smiled slowly, which were the footprints left by the murderer.

"Whew......"

Zuo Tingxue was still seriously thinking about how to solve the case, and suddenly there was a burst of screams in the room, and Zuo Tingxue hurriedly put down the things in her hand and walked into the bedroom.

In the little crib, the little white tiger kept barking with its feet on the edge of the fence, its eyes were open, and its little head was as cute as a kitten.

Zuo Tingxue took the little white tiger into her arms, stroked its head, and the little white tiger was affectionately attached to her arms, rubbing around, and from time to time she used her claws to grab Zuo Tingxue's hand and licked her hand gently.

"You're so cute, aren't you hungry?" Zuo Tingxue asked intimately.

Little White Tiger's eyes lit up when she heard what she was eating, and Zuo Tingxue was amused, the first time she had been so happy since she was reborn.

She hurriedly picked up the osmanthus cake on the table, broke the pastry, put it in the palm of her hand, and brought it to the mouth of the little white tiger.

The little white tiger is still too small, and although the pastries are already crushed, it can still only lick a few bites, but it is not easy to swallow.

Seeing this, Zuo Tingxue put the pastry in the milk and let the little white tiger lick it, and the cute little white tiger licked the milk obediently like a sensible child.

After a while, the little white tiger was full, it snuggled in Zuo Tingxue's arms, licking its little paws, Zuo Tingxue liked this little white tiger very much.

She looked at the little white tiger's bright little eyes and smiled, "You are so cute, I'll give you a name." ”

Zuo Tingxue thought for a while, "It's better to call you Su Su, and never forget the hatred of the Su family." ”

When the little white tiger heard this, he rubbed it on the left side of the snow, as if he was very satisfied with the name.

Zuo Tingxue was very happy when she saw the little white tiger so sticky, this was the happiest time she had ever been since she was reborn, and seeing the little white tiger was like seeing her own child.

The next day, Zuo Tingxue found the crown prince Zhang Kai and asked about the black sand: "Your Royal Highness the prince, where are you looking at this black sand?" ”

Zhang Kai looked at the black sand and rubbed it with his fingers, "This black sand is very precious, it is very good for self-defense, what are you doing with this black sand?" ”

Zhang Kai asked puzzledly, didn't she go out in the middle of the night last night just to get this black sand?

"Then do you know where there is such a black sand?" Zuo Tingxue asked again.

"This black sand, it's not everywhere, only the royal relatives will have such a black sand, you are all begging for this black sand, why don't you know where it came from?" The prince said that it felt even more strange here.

"This sand is only found in the palace, so it's strange?" Zuo Tingxue muttered, this black sand was left on the murderer's feet last night, and only the palace in the country has such a black sand, could it be? Is this possible?

"What's strange, this black sand is from the palace, this is a rare kind of sand, or is it a tribute from other countries." The prince continued.

Zuo Tingxue thought for a while and said, "Your Royal Highness the Prince, do you remember, who owns this black sand?" ”

This black sand is the favorite thing of the new prince Zhang Shuo and the national teacher Li Life, and they especially like to use it for self-defense.

Zuo Tingxue frowned, and she asked puzzledly, "Who is Li Lifu?" Why did she become a national teacher? ”

Prince Zhang Kai told Li Lifu as soon as he heard it, it turned out that Li Lifu was once the princess of Dongguan, Li Lifu came to Tanglin to be close, the two got along for a while, and the relationship was very good, but Zhang Shuo suddenly died, Tanglin Emperor suddenly became seriously ill and bedridden, it was Li Lifu who saved Donglin Emperor, so the emperor wanted to send Li Lifu back to China, but he didn't expect Li Lifu to ask to stay, and wanted to be a national teacher, Tanglin Emperor thought she saved herself, so she didn't deliberately ask for anything, so Li Lifu did Tanglin National Teacher.
