"Are you so sure?" Li Er looked at Zhang Nan and asked, Comrade Li Er is not very clear about the situation of Da Shi, after all, the contact between Da Shi and Da Tang was not so frequent before.

"Although the minister can't be said to be ten percent sure, but there is also eight or ninety percent." Zhang Nan thought for a while and said, now Zhang Nan can roughly determine that this new caliph of the Great Food is definitely a traverser.

Excluding this person's inquiries about the information done by Datang and his thoughts about Datang, Zhang Nan can basically determine the thunder alone.

Zhang Nan can responsibly say that if Dashi developed according to the normal level of science and technology, it would be too early for them to use gunpowder as weapons, but now they have almost the same level of science and technology as Datang, which is very revealing.

Of course, Zhang Nan can also be sure that this new caliph will definitely sit in his position through some special means, as a religious country, if you want to be the leader of a country, you need not only to have the means alone, but also to have an orthodox identity that can convince the public.

As a traverser, Zhang Nan really couldn't understand where this person's orthodox identity came from to be able to become the caliph of the Great Food, so his position was definitely unstable.

After all, when there was no him, Da Shi was already divided into two factions, and now there is one more of him, no matter which faction he is, the other faction on the other side will also look at him unpleasantly, which has nothing to do with whether he has made political achievements or whether he has led the people to prosperity.

So what Zhang Nan wants to do is to secretly support people from the other faction and make trouble with him in the big food, even if he can't overthrow him, he will disturb his mind.

"Your Majesty, the minister thinks that the first task now is to establish diplomatic relations with Dashi, get along with good relations, and it is best to exchange caravans." Zhang Nan suddenly became serious, which made Comrade Li Er a little unaccustomed.

"Establishment of diplomatic relations? Have trade relations? Why is that? This great eater has already put a knife on my neck, do you still want me to trade with him? Li Er asked a little angrily, in Li Er's opinion, at this time, building a business with Da Shi is tantamount to showing weakness, Comrade Li Er is not a person who is good at showing weakness.

"Your Majesty, there is a saying in the ministers, it is often not your friends who know you best, but your enemies, obviously we want to be the enemy of the big food, then we have to find out the bottom of him, and we must exchange the minimum price for the greatest return, right?" Zhang Nan said.

"Isn't it often not your friend who knows you best, but your enemy? Kind of interesting, you move on. Hearing what Zhang Nan said, Comrade Li Er immediately became interested.

"Although we know that Da Shi has an idea about us now, but after all, he hasn't done it yet, so we can establish friendship with him first, try his bottom line, if he is willing to establish diplomatic relations with us, it means that Da Shi actually doesn't want to go to war with us now, then we can have enough time to gather intelligence." Zhang Nan said with a smile.

"But if that's the case, wouldn't my Datang also be figured out by the Great Food?" Li Er asked strangely.

"Your Majesty, don't worry about this, we have to get to the bottom of the Great Eclipse, mainly to inquire about their new caliph, and when it is confirmed that he and his ministers are from the same place, we can send our spies to carry out rebellion activities in their city, of course, the foundation of all this must be based on our ability to communicate with the Great Eclipse freely and safely." Zhang Nan said.

"We don't have anything to hide, there is also a thunder eclipse, and as for the steam engine, I think they are about the same, but the flintlock pistol is not yet sure, so we still have hole cards in our hands." Zhang Nan continued.

"Well, you're right." After Li Er finished speaking, he began to think about it, it seemed that he was weighing the pros and cons, and the advantages and disadvantages of Zhang Nan's doing this were obvious.

The advantage is that Datang can take advantage of this time to find out what is going on in the Great Food Country, so as to better engage them in their country, but the disadvantage is also obvious, since the construction of transportation business, many things in Datang will also be exposed under the nose of the Great Food.

However, in Zhang Nan's opinion, these things are necessary sacrifices, and Zhang Nan does not expect to be able to hide them, after all, these things are based on science and technology, and they can't be stolen if they are stolen.

"And we have a more obvious advantage over Big Food." Zhang Nan said.

"What advantages?" Li Er asked.

After hearing this, Zhang Nan smiled and pointed to his nose.

"That's the minister." Zhang Nan said.

"You?" Li Er's face was strange.

"That's right, it's the minister, since that person is now their caliph, it means that he can't carry out the same free activities as the minister, and the minister will be able to better arrange the minister's plan, after all, the minister knows some things that others don't know. But I am a minister, he is a king, and I am destined to be more convenient than him. Zhang Nan thought very clearly.

If Datang and Dashi establish diplomatic relations, Zhang Nan even decided to take care of this matter in person, and Zhang Nan, who is not good at anything else, feels that he is still very talented, especially this person has his own Achilles' heel, as long as this is enough.

"I know, you go down first, I will think twice about this matter, and tomorrow morning, I will put this matter on the agenda." Li Er waved his hand and signaled that Zhang Nan could retreat.

Zhang Nan knew that Li Er's thinking problem couldn't be as simple as himself, so he didn't bother Comrade Li Er too much, and left the palace directly, and when Zhang Nan left, Comrade Li Er was still sitting on the chair and didn't know what he was thinking.

After leaving the palace, Zhang Nan returned directly to his house, and now Zhang Nan's pair of children can already walk around the house on their own short legs.

Every time Zhang Nan saw his children chasing me in the backyard, Zhang Nan felt that his life was complete. There's nothing happier than watching your wife and children together.

Now Junyan and Zhen Zhen can call out simple words such as father and mother very fluently, so as soon as they returned to the house, Zhang Nan held his children in his arms left and right.

"Lang Jun? How did you get back? Cui Yue heard the movement in the courtyard and also walked out of the house.

"There's nothing big on the prairie, and there's no point in me staying, so I'm back." Zhang Nan said with a smile.
