Nangong Yu pointed to the earrings and said to Nangong Yan: "These earrings are not only beautiful, but they can also save your life at a critical time." ”

Nangong Yan quietly looked at these seemingly ordinary earrings, did not speak, and waited for Nangong Yu to tell the mystery inside the earrings.

"These earrings are the treasures of the Xiaoyao Palace, and they will definitely not add up to more than five pairs. Yan'er, take a closer look at the difference between the earrings on these earrings and the earrings on yours?" Nangong Yu asked Nangong Yan with a serious expression.

Nangong Yan took off the earrings on her ears and took the two pairs of earrings and compared them carefully. Nangong Yan shook her head at Nangong Yu, except for the difference in appearance, she couldn't see any difference between the two pairs of earrings.

"I don't let you see the difference between the two pairs of earrings, which is also one of the functions of this pair of earrings. Nangong Yu said with a smile.

"Auntie, I don't understand!" Nangong Yan looked at Nangong Yu suspiciously, waiting for Nangong Yu to continue.

Nangong Yu put away the smile on her face and said, "You can't see it, this is the hidden function of this pair of earrings." These earrings are not much different from ordinary earrings in terms of shape and weight. Unless you have absolutely great eyesight or know the mystery beforehand, you will not be able to perceive that these earrings are not ordinary earrings. ”

"It's better to avoid the eyes of your opponents. The person who designed these earrings must have been a master of counter-reconnaissance. Nangong Yan quipped, with a mischievous smile on her face, like a little girl who was coquettish in her mother's arms.

"I don't know who designed these earrings. But how can the person who can design this pair of earrings not be a master?" Nangong Yu said solemnly as he looked at the pair of small and delicate earrings in his hand, his face full of admiration.

"A true master is never greedy for fame, and perhaps this is a low-key master. Nangong Yan also said with a straight face.

"I'm going to tell you about how to use these earrings and how they work. Nangong Yu pointed to the earrings in his hand and explained to Nangong Yan, "Although the two earrings don't look different, they are divided into left and right. The earring on the left ear has a pendant that rotates to the left, and the earring on the right ear rotates to the right. The function of the left and right earrings is also different. The earring in the left ear is used to convey information, and the earring in the right ear is used to cover the escape. The earring on the right ear is coated with a generous amount of magnesium. As soon as you press the switch, the earrings will form a flash effect directly in front of you, which is a good cover. The switch is just behind the earring. ”

"Yan'er, do you know what the smallest bird in the world is?" Nangong Yu asked Nangong Yan.

"I've read in books that the smallest bird in the world so far should be a hummingbird. Nangong Yan replied to Nangong Yu.
