In fact, Li Tai tried it last night and was also taken aback, saying that it is impossible to say that it is a demon method, everyone can try it and complete it, Li Tai explained, "You can also try it, you can do it." ”

"It's so simple, just a fire?" The Tianzhu envoy shook his head with a wry smile, "It was our Tianzhu who lost." ”

Li Tai also smiled and nodded.

Li Er sat back in his place, his heart fluctuated, looking at Gu Qing's eyes more and more curious, how much ability this kid still hid.

Li Chengqian couldn't speak for a long time, and he only had deep jealousy in his eyes for Li Tai and Gu Qing.

Cheng Yanjin stepped forward to pick up the bottle, but he couldn't pour out the eggs, "Gu boy, is there any mechanism!" ”

"Nope." Gu Qing said innocently, "You can really go in like this, but it's a bit complicated to say, and it's hard to explain!" Uncle Cheng might as well go home and try it to succeed. ”

"I have a question!" Songtsen Gampo stepped forward and said.

"Please ask!" Li Tai said.

"Let's stop pretending! Anyway, as long as you can't answer, we can get through this level! Songtsen Gampo looked directly at Gu Qing, "I know it's all because of your Gu Qing's presence, this time I will challenge you directly!" ”

"Is this proper?" Gu Qing looked back at Li Tai.

The envoys who were sitting were silent, and Li Tai said with a smile, "Yes!" ”

"Gu Qing, listen up!" Songtsen Gampo opened his mouth and said, "I have always admired the knowledge of the Tang Dynasty for a long time, and the Central Plains weights and measures!" Today I'm going to try weights and measures, I want you to measure a tree, but you can't measure a tree with anything! I'm going to see how you measure it. ”

"You're talking nonsense!" Cheng Yanjin couldn't sit still, "Did you let Gu Xiaozi measure with his eyes?" The old man thinks you want to sleep with the girl, and you want to go crazy. ”

"Hahahaha!" Niu Jinda burst out laughing very cooperatively.

"It's too easy." Gu Qing smiled and said, "I'll give you another chance to change the subject." ”

"No change! That's it! Songtsen Gampo said resolutely.

"How many people are watching?" Gu Qing shook the folding fan, "I don't want to win too easily, and I don't want you to lose too ugly, it's shameful enough for you to go to the Qinglou and not give money, or the dignified Tubo monarch, I am very merciful, you can change the topic to a more difficult one." ”

"Don't change!" Songtsen Gampo said loudly.

"Really not changing?" Gu Qing asked again.

"Don't change!" Songtsen Gampo said again.

"I see if you can't answer and deliberately want to change the topic." Lu Dongzan stood aside.

Li Tai came to Gu Qing's side and whispered, "Is the energy coming out?" ”

"Yes!" Gu Qing bowed his head and said, "You pick a tree!" ”

Everyone followed out of the Taiji Palace, and Songtsen Gampo saw a tree in the palace garden and said, "This is it!" Gu Qing, you measure. ”

"Give me a measuring tape." Gu Qing said to Li Tai, and then saw that the others were puzzled and explained, "Don't worry, I won't measure the tree, I will measure other things." ”

After taking the ruler, Gu Qing said to the Turkic envoys, "Come and help me." ”

"What are you going to do?" The Turkic envoys were a little nervous in the face of Gu Qing, and the scene in front of the city gate yesterday was still in their minds.

"Come here!" Gu Qing stood under the tree and let the Turkic man stand up, looked at the sunlight for a long time, glanced at the shadow on the ground, and began to measure the height of the Turk.

"Don't move!" Gu Qing shouted.

The Turkic envoy immediately stood straight.

Li Tai has been watching Gu Qing's movements, thinking that with his knowledge, he might be able to deal with these envoys, but he came up with this rule in order to be in the limelight in front of his father, and now this limelight has been taken away by Gu Qing.

Gu Qing had already begun to measure the shadows, measured the length of the shadows of the Turkic people, measured the length of the shadows of the trees, and began to write and draw on the ground.

"I measured it, and there are three out of ten battles!" Gu Qing put down the measuring tape, "Songtsan Gampo, isn't it like this." ”

Songtsan Gampo didn't speak, Li Er immediately asked Wang Qin to measure the tree, sure enough, there were three out of ten battles, that's right!

Li Tai looked at the sun and looked at his shadow, as if he understood something.

"Then now it's my turn." Gu Qing said to Songtsen Gampo, "There is a person who comes to the two gates, there is a living gate and a death door, you have to go out from the birth gate, but you don't know which one is the life gate and which one is the death door, there are two guards guarding each door. ”

"There are two other guards, only one of whom is telling the truth, and the other is telling a lie! I can only ask the two guards one question each," Gu Qing said, "How do you ask to be sure that one door is a living door." ”

"A truth and a lie." Songtsen Gampo began to meditate. "How to determine which guard is telling the truth and which is lying, and you can only ask it once."

There was a large group of people standing in the palace garden, Li Er was thinking about it, Gu Qing's question was difficult, but there were some things that were revealed, the door of life, the door of death! People will make a lot of choices in this life, just like the changes in Xuanwumen, they can't make mistakes.

When you make a choice, you also have to look at what you are saying is true or false, and when you are at a loss and start to hesitate, you have to believe who is telling the truth and who is telling a lie.

"It's really hot." Gu Qing blocked the sunlight with a fan, "Songtsan Gampo, I said can you hurry up!" They all suffered from heat stroke. ”

"I ...... I'll give you some time. Songtsen Gampo paced back and forth, "Shengmen? Death's door? Truth, falsehood? You can only ask once, how to ask! ”

"It's the same when we make choices, you often don't know if the people around you will tell the truth or lie, sometimes they will use lies to lead you into a trap, and sometimes they will tell the truth to help you." Gu Qing said.

Seeing that Songtsan was sweating profusely, Gu Qing said again, "Why don't you change the simple question, the sun in the morning looks big, but it is cooler, and the sun at noon is smaller, but it is hot!" I ask you, which is closer to the sun at noon or in the morning! ”

A question has not yet come to mind, and another question is thrown.

Seeing that Songtsen Gampo wanted to speak and stopped, Gu Qing asked again: "Then I'm talking about a simpler one, under what circumstances is one plus one not two." ”

“……”

"Still can't answer?" Gu Qing shook his head and sighed, "Then it's simpler, as long as people read it, they will mispronounce any word!" ”

“……”

Gu Qing: "Did the chicken come first or the egg came first?" ”

Songtsen Gampo: "......"

“……”

"What the hell do you ask! Which one is born! Songtsen Gampo couldn't help it, "I admit defeat!" Gu Qing, tell me the answer! ”

Gu Qing whispered a few words in Songtsen Gampo's ear, and everyone listened with bated breath, stunned that they didn't hear what they said clearly.

After listening to this, Songtsen Gampo laughed and said, "Gu Qing, I admire!" ”

"Concession." Gu Qing smiled and arched his hand.
