"No problem! No problem! ”

Dongmen hurriedly said.

The young man nodded, seeing that nothing was wrong, and was about to turn away.

At this time, Dongmen said: "I don't know if you are free now, you are a formal researcher, I don't know if I can ask you for some knowledge." ”

The young man wanted to refuse, after all, he and his lover did not know each other.

But after thinking about it, he didn't have a clue about his affairs anyway, and the meeting was fate, so he agreed to Dongmen's request.

Seeing that the young man really agreed, Dongmen was naturally overjoyed, and decided ruthlessly to invite this official researcher to a good meal with the money he had worked so hard to save, even if he had just eaten, but there was nothing wrong with inviting him to eat.

And the people take food as the sky, and inviting someone to eat is also a tribute to someone.

In a good restaurant in Chang'an City, the two found a window seat to sit in.

After ordering a few expensive dishes, Dongmen only felt that his heart was dripping blood again.

"My name is Yunfeng! I don't know what you call you? ”

Young man.

"Oh! Prisoners at the Lower East Gate, you can even connect with my East Gate. ”

"I don't know what Brother Dongmen has to ask?"

"This brother doesn't dare to be a word, he doesn't dare to be! I would like to ask Brother Yun if you can learn about cement. ”

Yun Feng was stunned for a moment, and became a little vigilant.

"Are you really from the Academy of Sciences? Do you have a certificate? ”

Hearing this, Dongmen hurriedly rummaged in his arms and handed Yun Feng a booklet decorated with animal skins.

"Trainee researcher? Or is it a special approval from the king? ”

Yun Feng looked at the east gate with some surprise.

Dongmen was a little embarrassed and said: "I can't hide it, the experience of coming down to Chang'an is quite tortuous. ”

"It's okay today, if it's convenient in the east gate, you might as well say a thing or two."

Dongmen sighed lightly when he heard this, and told Yun Feng about his experience.

After Yun Feng heard this, he also felt a burst of emotion in his heart, and at the same time, he also admired this person a little.

To be able to enter the Academy of Sciences from a businessman is no less difficult than passing the imperial examination, and if there is a trace of unluck, I am afraid that this person is still living in a prisoner of war camp.

"The king asked you to build that kind of bridge in a year?"

Yunfeng confirmed again.

Dongmen nodded and said, "Yes!" It's just stupid, and he hasn't completed the king's explanation.

”

"So you think the advice given by the king should be something to try?"

Dongmen said: "Yes, but I don't know what the cement is, and I don't know where to start for a while."

”

Yun Feng smiled: "What's so difficult about this, in fact, you have already seen cement." ”

Dongmen said with a puzzled face: "Brother Yun, don't make fun of me, how can I ever see cement."

”

"Let me ask you, have you seen the city wall, the city wall of Chang'an City."

Dongmen felt that what Yun Feng said was nonsense, he had lived in Chang'an for half a year, if he hadn't seen the city wall, the only possibility was that he was blind.

But seeing that Yunfeng was not joking, he couldn't help but ponder.

"Brother Yun is saying that the cement is on the city wall?"

"Even if you don't win, you don't want to!"

Seeing that Yunfeng was still selling Guanzi, Dongmen was suddenly a little anxious.

"I also ask Brother Yun to solve my doubts.

”

Yun Feng said: "Actually, you can guess one or two from the name of cement."

Cement cement, water is mud, dehydration is stone, so you still don't understand?

”

Dongmen frowned and pondered for a long time, patted his head sharply, and asked in surprise: "Brother Yun is saying that the thing connected by the masonry of the Chang'an City Wall is the cement?" ”

Yun Feng said: "Brother Dongmen really can get through at one point, yes, that thing is cement, after this thing is fossilized, it is extremely hard, water and fire are invulnerable, and it is no different from masonry." ”

Dongmen's reaction was also extremely fast, and he immediately guessed Yang Hao's intentions.

"I'm so stupid that I only think about using wood, but I don't know how to use bricks and stones, and the king is really a god and a man."

Yunfeng agrees.

"The wisdom of the king is beyond the reach of people, if we can have the wisdom of the king, how can it be so difficult."

"Brother Yun also has something to worry about?"

Yun Feng took a sip of water and said, "Speaking of which, the troubles encountered by you and me are quite similar.

You are the bridge builder, and I am the shipbuilder.

”

Dongmen was a little puzzled: "Doesn't my Daqi already have a ship?" Why is it so difficult to be in the cloud? ”

"Brother Dongmen doesn't know, now my Daqi ship has too many defects, and it is impossible to sail on the open sea, and some slightly stronger winds and waves will cause the ship to be destroyed and people will die!"

"Voyage to the open sea? What does this mean? ”

"This world is very large, at the end of the state is an endless sea, it is said that there are countless treasures on the sea, if those treasures are brought to me, the people will be richer, but we have studied for a year, but there is still no progress.

How can I not live up to the expectations of the imperial court?

”

Dongmen sighed: "I can't imagine that everyone has their own troubles!" ”

Yun Feng said: "Although it's annoying, aren't you and I also happy with it?" It is better to study these novelties than to worry about those government affairs.

If I had to choose again, I would still choose the Academy of Sciences.

”

Dongmen can clearly feel that Yunfeng's sense of pride, which is a recognition of his identity, and a sacrosanct temperament arises spontaneously.

When the wine and food came up, the two chatted while eating, and the more they talked, the more speculative they became.

Both of them belong to the kind of people who are full of reverence for science, and devote all their hearts to their hobbies.

The two talked about everything from trivial matters in life to academic issues, and although they had only known each other for one day, they were like old friends for many years.

Yun Feng's comprehension of Dongmen was impressive, although there were many things limited by the level of knowledge, but this did not affect Dongmen to express his opinion in the slightest.

Even if there are some problems where the donkey's lips are not in the horse's mouth, some of the ideas for solving the problem still give Yun Feng a bright feeling.

I only feel that if this person is given a certain amount of time, I am afraid that he will participate in the imperial examination again, and he will not be this person's opponent at all.

Luckily, this situation could not happen at all, Yun Feng was not jealous, but was happy to meet such a smart person.

This meal, from noon to dusk, although Dongmen drank dizzy, but the consciousness was still very clear.

He felt that today was his lucky day, and he benefited a lot from the afternoon of communicating with Yunfeng, and some of Yunfeng's suggestions were also very feasible.

On the way back to his residence, Dongmen struggled to keep himself awake, and with the new materials, his thinking was greatly expanded.

Previously confined to wooden bridges, he now had so many ideas in his head that he couldn't wait to give it a try.

And in the twilight, Yang Zhizheng was in great pain with a mountain of information.

And these are just a few of the complicated government affairs over the years.
