Su Chen did not lead the army personally this time. To attack Shiraz, there was no need for him to personally lead the army.
After the army left, Su Chen called the Byzantine envoys and asked them for some detailed information about the cannibals.
Many things about Dashi puzzled Su Chen.
Especially the magical prime minister of Dashi, Su Chen felt very strange when he was in the Tang Dynasty.
Why did a follower of the prophet know Chinese and still want to go against the Tang Dynasty?
Later, I asked Rapupasu, Elsa, Hashim and others, and they all knew very little about the Great Food Prime Minister.
Su Chen hoped to get some information from Byzantium, but the result disappointed Su Chen again.
The Byzantine envoy only knew that the Prime Minister of Great Eclipse was one of the first to follow the prophet.
I wasn't very good at first. I just followed the prophet and did some chores.
It was not until two years before the death of the Prophet that he was suddenly appointed as the Prime Minister of Food by the Prophet.
Moreover, this Prime Minister of Food seems to be quite old and not in good health. Masters and nobles rarely see him.
After listening to the Byzantine envoy's story, Su Chen sighed inwardly: He probably had to defeat the cannibal and capture him and ask him personally to find out what was going on.
Just as he was about to send the Byzantine envoy down, Ferdowsi, whom he hadn't seen for several days, suddenly came to see Su Chen.
"Commander, the kerosene you are looking for has been found!"
Su Chen was overjoyed after hearing this: "Finally we have good news!"
Everyone knows how rich the oil resources in the Persian Gulf are, but this does not mean that oil will come out of Su Chen just digging a hole.
With the technology of the seventh century AD, it was difficult to mine. It basically appeared naturally and was discovered by people.
Rapupasu and Ferdowsi both knew about this thing, but they didn't know exactly where the oil wells were.
Su Chen has asked the Persians to look for this matter for a long time, and finally found it today.
Although Su Chen can't make Greek fire, with oil, he can still make something with similar effects to Greek fire.
"Oh, by the way, I heard that the Greek fire was obtained from you by the Great Eater?"
"Why did you give such a powerful weapon to the enemy?"
Su Chen asked the Byzantine envoy.
This matter is quite strange to Su Chen. According to his memory, in history, Greek fire was a weapon used by Byzantium to fight against the cannibals. Byzantium had such a treasure and would not let the cannibals steal it.
How come he has turned into a cannibal, carrying Greek fire and killing people and setting fires everywhere?
Hearing Su Chen's question, the Byzantine envoy looked a little ugly.
"This matter is indeed an oversight of our country. We did not expect that the royal family and nobles responsible for the production of Greek fire would suddenly rebel and hand over this important weapon of life and death to the cannibal."
The Byzantine envoy did not hide this matter, and it cannot be hidden. If Su Chen wants to know, he will definitely find out.
The Byzantine envoy suddenly said: "I have also heard that the gunpowder formula was distributed by your country."
"And it seems that the cannibal has even mastered the technology of artillery casting!"
Now it's Su Chen's turn to be embarrassed!
"Hey, let's not laugh at each other about this. As the country grows, there will always be some scumbags who take advantage of others!"
The Byzantine envoy nodded in agreement, and then both parties made a tacit agreement not to mention these family scandals!
"Commander, if you are looking for fire oil, you must also be looking for Greek fire."
"Since you and I are allies, how about exchanging some technologies with each other?"
Su Chen glanced at the Byzantine envoy and said, "You want to exchange Greek fire for me for artillery casting technology?"
The Byzantine envoy nodded: "Commander, we are facing a great enemy. Hiding from each other will only make it easier for the cannibals."
"And with the commander's wisdom, he should be able to judge that it won't take long for both of us to obtain these two technologies through various methods. There is really no need to hide them from each other."
Su Chen smiled: "Are you sure I haven't learned how to make Greek fire?"
The Byzantine envoy also laughed: "General, the method of making Greek fire is a thousand times more complicated than the gunpowder formula. The foreign minister does not think that the General can get it in such a short time."
Su Chen spread his hands: "What you said makes sense. We really shouldn't take advantage of each other and eat people."
"Since you want to exchange Greek fire for cannon-making technology, it's not impossible,"
"But I would like to remind you that the artillery casting technology requires a lot of metal smelting. Otherwise, even if you get the artillery casting technology, you will not be able to cast a suitable artillery in a short time."
The Byzantine envoy said: "Thank you, Marshal, for reminding me! We know this, and we also found out that the cannons made by the cannibals often kill their own people!"
Su Chen smiled and said: "In that case, do you carry the Greek fire technology with you?"
The Byzantine envoy smiled and said: "To be honest, Commander, this is one of our missions this time, so we carry it with us."
"It's in the salute of our residence. I'll go get it for the commander right away."
With that said, one of the Byzantines hurried out and went back to get something.
Su Chen said: "That's good, I'll ask someone to give you the artillery casting technology,"
"To tell you the truth, what I give you is a technical manual summarized and compiled by the cannon maker himself. It is much better than the one in the hands of the big eater."
Ever since the Byzantine envoy was interested in asking Su Chen for cannon-making technology in Medina last time, Su Chen was interested in making a deal with Byzantium.
Anyway, this thing has been passed to the hands of the big eater, and it will definitely spread all over the world in the future. It is better to exchange it for something good while it still has some value.
However, Su Chen didn't bring any drawings explaining the cannon casting technique, so he had to ask the craftsmen accompanying the army to temporarily compile one.
They were originally senior craftsmen who cast cannons. This time they joined the army as auxiliaries to help maintain the cannons. It was not difficult to produce such a cannon-casting technical manual.
With this exchange of artillery casting technology and Greek fire manufacturing technology, both parties got what they wanted and were very happy.
Byzantium believed that its iron smelting technology must be better than that of the Great Cannibal, and it would definitely be able to forge multiple artillery pieces that were more powerful than the Cannibal's cannons.
Although Su Chen felt that he could make something similar to Greek fire, it was just a guess, and it would probably take a lot of time to experiment.
In the current duel with the giant cannibal, time is precious, so it is better to just use a set of mature techniques to quickly bring out the Greek fire!
"By the way, when you send the technical materials back, please tell His Majesty Heraclius,"
"I especially look forward to seeing the Byzantine army in the Mesopotamia. Then I can send you a batch of cannons used by our Tang army!"
The Byzantine envoy was refreshed, but immediately restrained himself and said to Su Chen: "Commander, our army also looks forward to meeting your army victoriously in Ctesiphon as soon as possible."
