"This is called a telescope, which was left by the previous master." Mei Niang said.

"It's the former queen's mother?" Su Yunxi took it from Mei Niang's hand, she remembered that in the study of the bamboo garden of Dayan Sufu, she had seen a picture of this kind of thing, Su Yu drew a similar thing on the page with a brush, she saw it at that time, and thought it was a bamboo flute or something, but she didn't care too much.

In addition, there are too many books in the Zhuyuan study, and the ones she has read in her memory and those she has read since she came to this world are all read in a hurry, and she has not carefully studied those suspicious things one by one.

There are many tigers and wolves in the backyard of Sufu, Dayan Capital City, good and bad things one by one, until she was assigned to the northern land, she didn't have much time, these things, she just remembered them in her mind after reading them, but she didn't think about them carefully.

"It was given to the master by General Su, General Su is a very smart woman, and will do a lot of strange things, including the fan just now, which was also left by her, there is a lot of miasma in the Western Regions, and the air is damp most of the time, the master is very sick for a while, and his body is full of red spots, General Su made a small fan, and gently blew the body of the master through the quilt, and the master is not itchy, which is very effective, and later, when other tribes come to make trouble, throwing poisonous powder, General Su designed a big one, The Emperor Taishang is really handy in dealing with those tribes. Mei Niang said.

"Auntie, your intelligence is very good like your mother's mother, you can do anything, there are a lot of strange ideas in your head, you are not mortals!" Murong Qing sighed.

Su Yunji took the bamboo tube and looked into the distance, one end of the bamboo tube is made of colored glass, this world can't make such a transparent glass, but after the glass melts, it is polished to form an arc shape, after the double pieces overlap, it is projected out, and then the light reflected in it can also see the distant scene very clearly.

"It's not bad, the medicinal powder on the ground has worked, and at least half of the snakes have their skin and flesh to death." Su Yunxi looked at the scene in the distance and said.

The long black serpent, they can't see it from this upstairs.

It was only because of their excellent eyesight that they could clearly see the white-clothed men in the distance slowly walking towards the city gate.

The thin black snake on the ground, they naturally couldn't see clearly.

However, with this telescope, you can see clearly.

"Telescopes, she can make telescopes?" Su Yunxi handed the bamboo tube to Emperor Yuxuan, turned around and walked to the side.

The potions and powders on the table were piled up on the table, and no one else had come to this room from beginning to end, and Mei Niang was here alone and carefully blending, which made her curious.

"The people I trained in the past can lead their own troops to fight, as long as they know that they have been called, they will contact each other, some of them are doing business in the city, some are married to soldiers in the army, and some are infiltrated into various tribes, so their news is much better than mine, this time, the Five Poison Clan is the main leader, and naturally deal with the Five Poison Clan, they will have a number, and there will be a response, so it is not my turn to make a move." Mei Niang said with a smile.

"Sure enough, it's well-trained!" Su Yunxi nodded, she was not praising Mei'er, nor the former queen, she thought, she should have just begun to really understand Su Yu.
