And the result did not disappoint Zhang Nan, everyone's paper was still white, except for the questions that were memorized, almost nothing was left. However, when he walked to Lu Dongzan's side, Zhang Nan said "um".

Lu Dongzan's exam paper attracted Zhang Nan's attention.

Although Lu Dongzan, like everyone else, still didn't have the final answer to this question, Zhang Nan saw something unusual on Lu Dongzan's exam paper.

Unknown.

Lu Dongzan actually thought of setting up unknowns in the process of answering, and after carefully looking at Lu Dongzan's solution process, Zhang Nan found that Lu Dongzan was stumped by the second of one yuan and two times.

Although Lu Dongzan's solution method is already very ingenious, he can't avoid the difficulty of the quadratic, and what Lu Dongzan calculated frantically just now is also trying to find a way to solve this quadratic.

But thinking that the establishment of the unknown has consumed a lot of time for Lu Dongzan, and as for solving the difficulty of quadratic, Lu Dongzan has no time at all.

After reading Lu Dongzan's exam papers, Zhang Nan secretly sighed in his heart: "It's better to underestimate this Tubo person, his brain is really good." ”

After putting down Lu Dongzan's exam paper, Zhang Nan handed it over to Li Er and said, "Your Majesty, after the inspection of the ministers, none of the people present answered this question. ”

Li Er actually expected this result, if someone answered it, it would really surprise Li Er, but on the surface, Li Er still had to pretend that I was unhappy, but I couldn't show that I was unhappy.

"It seems that all the envoys have not exerted their full strength, but this is to choose a marriage for the princess, you still have to work hard." Although Li Er was expressionless, the envoys present all felt that Li Er was angry, angry that no one could answer this question, and they all hurriedly lowered their heads.

But there was only one person, that was Lu Dongzan, who still held his head high, and then stood up and arched his hand to Li Er and said, "Emperor Tang, I feel that in such a short period of time, no one will definitely be able to solve such a difficult question. ”

Hearing Lu Dongzan say this, Comrade Li Er immediately raised his eyebrows, and then said: "Could it be that the princess thinks that the princess deliberately made things difficult for you?" ”

"The minister doesn't dare, but the minister has just solved this problem halfway, although there is no time now, but the minister still wants the Tang Emperor to come out with a well-educated person to solve this question, and solve the confusion in the minister's heart."

Lu Dongzan said this very cleverly, although Lu Dongzan did feel that this question was deliberately set up to make things difficult for them, but he didn't say it, but asked Li Er to send someone to solve this problem, if even Datang's own officials can't answer it, it is enough to prove that Li Er deliberately made things difficult for them.

After Li Er heard this, he said: "Well, since the big treatise has said so, then I will let someone answer it, Qingquan, how about it, can you answer this question?" ”

"You can try it." Zhang Nan arched his hand.

"Okay, I'll give you an hour, and if you can solve this problem, I'll be rewarded." Li Er said with a smile. Li Er smiled, and Zhang Nan also smiled.

Although Lu Dongzan knew that Zhang Nan was favored by Li Er, Lu Dongzan thought that Li Er loved Zhang Nan just because of Zhang Nan's identity.

Zhang Nan sat on the side of the small table, picked up the brush and pretended to be, although Zhang Nan could not use the brush to write regular script, but it was still possible to write Arabic numerals with the brush Zhang Nan.

Within five minutes, Zhang Nan put down the brush, stood up and said: "Your Majesty, the minister is fortunate not to be dishonored, and he finally solved this problem." ”

Hearing Zhang Nan say that he had solved it, Lu Dongzan immediately surrounded him and saw it, but he didn't understand what Zhang Nan wrote on the paper, all of them were like ghost drawings, and Lu Dongzan couldn't understand it at all.

"Since the adult said that the question has been solved, then please tell the adult, what is the answer to this question?" Lu Dongzan was reluctant to admit in front of so many people that he couldn't understand what Zhang Nan wrote, so Lu Dongzan only needed the answer.

"Naturally, this answer is ten cents, if you don't believe it, you can put this number in this question to see if it is ten cents." Zhang Nan said with a smile.

After listening to the answer, Lu Dongzan immediately walked to his paper and counted it again, this calculation is really ten cents.

Seeing Lu Dongzan's dejected appearance, Li Er knew that Zhang Nan was not wrong.

"Eh, you envoys don't have to be like this, this is just the first exam question, there are still exam questions waiting for you later, and the one with the most answers is Gao Yang's horse." Li Erdao.

Hearing Li Er say this, everyone cheered up again, after all, there was still a chance in the back, but what they didn't know was that the exam questions in the back were more difficult than the other.

"This first question is to test your arithmetic, and this second question is naturally to test your talent, please make a poem describing the princess's appearance in the shortest possible time." Zhang Nan said.

Before Zhang Nan finished speaking, an envoy stood up and said, "Dare to ask where the princess is now?" ”

"Princess? This is the princess with her head covered, please answer. Zhang Nan said. After Zhang Nan finished speaking, a woman walked out with the support of the maid, this was naturally Gao Yang, but Gao Yang's face was covered by a red cloth, and the clothes she was wearing were gorgeous.

After listening to Zhang Nan's words, everyone present began to rack their brains and think, after all, they had never seen what the princess looked like, so it was even more difficult to use her appearance as a poem.

After all, if there is anything that is not in line with the writing, it is not close to the princess's appearance.

Zhang Nan's question also makes it clear that he wants to bring each envoy into the ditch, after all, there are a thousand Hamlets in the hearts of a thousand readers, and the princesses in their minds are naturally different.

But no matter how much these envoys think, it is impossible to really write the princess's appearance in the poem.

When the appointed time had come, each envoy recited his verse next to each other. But Gao Yang, who was covered with his head, shook his head every time he listened to it, because no one made poems that fit her appearance.

Gao Yang is not the biological daughter of Empress Changsun, and the envoys present don't know that they are completely based on Empress Changsun's appearance to compose poems, and the poems made are naturally very similar to Gao Yang's appearance.
