Heraclius is a battle-hardened Roman emperor, from the Tang weapons brought by Bahra, he can almost conclude that the army of the Tang Empire far away in the east can definitely be called very elite, even if he has confidence in his Roman legions, but he has to admit that if two Tang armies with the same number meet the Roman army, he is not sure of victory, not to mention that Bahra's last words make him very vigilant.

"What is the most terrifying thing about Datang's army?" Heraclius asked in a deep voice again, if these weapons are not enough to explain the terrible Tang army, then he has to reassess the strength of the Tang Dynasty, and even before Bahra said that their Rome, Persia, and Great Food together are not as good as the Tang Dynasty, maybe he is not exaggerating.

"Your Majesty the Emperor, these weapons can only be regarded as the standard weapons of the Tang Army, in fact, they also have a very special weapon, collectively known as firearms, this kind of firearms I have not seen with my own eyes, because the Tang Army attaches great importance to this kind of weapon, and it is strictly forbidden to flow out of the army, but in the foreign operations of the Tang Army, they have used firearms many times, it is said that this firearm is like a thunderbolt, it can explode in the enemy's army, killing and injuring dozens or even hundreds of people at a time, before they were able to destroy the Turks who were more powerful than themselves in one fell swoop, This firearm plays a key role! ”

"Firearms? Is it the same as our Greek fire? Heraclius hesitated for a moment when he heard this, and then guessed, after all, people who have never seen firearms really can't imagine what kind of weapons firearms are.

"It's different, although the Greek fire in Rome is powerful, it is only an oil that can be burned, but the firearms of the Tang Dynasty can explode, and they can be made very small, and each soldier wears some, so that when fighting with the enemy, you can first use firearms to disrupt the enemy's formation, and then crush the enemy in one fell swoop!" Bahra spoke again.

Datang firearms have always been in absolute secrecy, except for the people in the army, few people in the outside world have seen it, so Bahra as a Hu man, naturally he has never seen it, so his understanding of firearms is only hearsay, and even deliberately exaggerated the power of firearms, in fact, the grenades carried by ordinary soldiers can kill and injure a few people at most, and if you want to kill and injure hundreds of people, you must at least use the huge gunpowder bag that blows up the city gate.

After listening to Bahra's description of firearms, although Heraclius still couldn't imagine what kind of weapon firearms were, he already knew that this weapon was definitely a powerful weapon that could determine the outcome of the battlefield, although their Roman Greek fire was also very powerful, but it needed a huge oil tank, so it could only be used on ships, which was much worse than the firearms of the Tang army.

"Only in terms of weapons, the Tang army can almost be said to be better than any army in the world, but if it is only with excellent weapons, other armies may have a chance to defeat the Tang army, but what is even more terrifying is that the national strength of the Tang Dynasty is very strong, their territory is definitely larger than Rome combined, and the population is large, plus the Tang people are good at farming, the country is very rich, I have seen some people of the Tang Dynasty feed livestock with grain, make wine with grain, and so on!" Bahra seemed to feel that the blow to Heraclius was not enough, so he once again boasted of the national strength of the Tang Dynasty.

"The country is vast, the population is large, the food is abundant, and the army is strong!" Heraclius listed the advantages of the Tang Dynasty that he had summed up at this time, and the expression on his face was also a little lost, these were all things he dreamed of for Rome to achieve, but he didn't expect that there was already a great empire in the far east that was worth chasing after him.

"The capital of the Tang Dynasty is called Chang'an, with a population of more than one million, it is the largest city in the world, and they have several big cities with a population of about 500,000, silk is worth a thousand gold here in Rome, but it is a clothing that ordinary rich people can afford to wear in the Tang Dynasty, and speaking of His Majesty the Emperor, you may not believe it, the Tang Dynasty has a tool called a hot air balloon, which can make people fly in the sky!" Bahra added again at this point.

Hot air balloons were only used in the army at the beginning, but the principle of this thing was too simple, and it was quickly cracked by some smart people, so some people began to make it in the people, of course, it was only used by some rich and idle people to play, after all, the practical value of hot air balloons in this era was not high, even in the army, it was only used as a lookout for the enemy.

"Okay, you don't need to say it, I already know the strength of Datang, it's a pity that Datang is too far away from us, otherwise I really want to go and see the prosperity of Datang in person!" Heraclius waved his hand.

Whether it is a metropolis with a population of more than one million or a flying hot air balloon, it has exceeded Heraclius's imagination, and it has also dealt a big blow to him, after all, no matter from which point of view, Datang has a crushing advantage over Rome, which makes his self-esteem really unbearable.

Bahra has been observing the change in Heraclius's expression, and at this time he also felt almost the same, and then spoke again: "Your Majesty the Emperor, the Tang Emperor is one of the wisest emperors I have ever seen, before I asked the Tang Dynasty for help on behalf of Persia, although he wanted to help us, but the Tang Dynasty was too far away from Persia, but His Majesty the Wise Tang Emperor pointed out that the distant Tang Dynasty could not save Persia, and the only thing that could save Persia was His Majesty's Rome!" ”

Hearing the Tang Emperor mention his empire, Heraclius finally regained some confidence, and then he also remembered that Bahra had said that he had a letter written by the Tang Emperor to himself in his hand, but just now he was hit by the strength of the Tang Dynasty, and he forgot about it for a while, so he hurriedly asked: "Where is the letter from the Tang Emperor?" ”

Bahra had been waiting for Heraclius's words for a long time, and at that moment he took out a beautifully made gold cylinder from his arms, the lid on which was sealed with fire paint, this gold cylinder was built by the craftsmen of the Tang Dynasty, which could protect the letters inside, and secondly, it also represented the importance that the Tang Dynasty attached to Rome.

Bahra opened the golden cylinder with his own hands, and then poured out a scroll from it, this letter was actually written in the form of a holy decree, and the whole scroll was also very beautifully made, and then Bahra presented the scroll to Heraclius, which should have been taken by the eunuch at this time, and then forwarded to Heraclius, but Heraclius did not care about this, and grabbed the scroll and opened it to see it for himself.

Li Shimin's handwritten letter is naturally written in Chinese characters, but it was translated in Latin next to it, after all, there are many Persians in the Tang Dynasty, and some of these Persians know Latin, and the Eastern Roman Empire used to use Latin, even if it is changed to Greek now, but the general nobles have also learned Latin, and Heraclius naturally understands it.
