It was the first time for scientific researchers in the Arab Empire to come into contact with computers. Their understanding of computers was almost zero.
For those batch processing software, they don't even know how to program, let alone write it.
It is basically impossible for them to compile those software themselves.
Let alone them, except for the computer builders in Huaxia City, no one else has that ability now.
Even the people recruited by Datang's Scientific Research Department were a little short of qualifications.
As for them going to the Datang Scientific Research Department or the Huaxia City Scientific Research Department to steal these software, it is almost impossible.
After several days of experiments, the scientific researchers in the Arab Empire had no solution to the problem at all.
They know too little about computers and cannot make major breakthroughs in a short period of time.
At this point, they had completely given up.
Faced with this situation, the king of the Arab Empire had to accept this reality.
For them, this is extremely bad news.
The technological gap between them and Datang was originally huge.
But now, after Datang has computers, the scientific research gap between the two sides will be further widened.
I'm afraid that within a few years, their national power will be completely crushed.
At this point, the king of the Arab Empire felt more and more that the best time to deal with the Tang Dynasty was now.
Moreover, we absolutely cannot wait any longer, we must take action now.
Now is probably the time when the gap in national power between the two sides is at its smallest, and they don't have any capital to wait any longer.
And since they are ready to take action against Datang, they must gather their strongest strength.
Before Datang could react, he gave Datang a head-on blow.
Next, the king of the Arab Empire secretly gathered an army of 500,000 people and displayed it on the border between the Arab Empire and the Tang Empire.
But this time, the king of the Arab Empire was going to appoint the veteran Khalid, Ibn Walid.
Khalid, Ibn Walid, was a veteran of the Arab Empire. He conquered the north and south, suffered only one defeat in his life, and made great military exploits.
In the original historical trajectory, this veteran had died many years ago.
In this life, Khalid lived a few more years.
To this day, although he is old, his sword is still young.
Of course, Khalid's defeat was actually at the hands of the King of Shu in the Tang Dynasty.
This time, when the king of the Arab Empire first found Khalid, Khalid refused.
"King, the Tang Dynasty is too powerful. Although after many years of development, our military strength is still not as good as that of the Tang Dynasty fifteen years ago. After fifteen years of development, the current strength of the Tang Dynasty has reached
How far has it come?"
"The chance that we can win against the Tang Dynasty is really very small. And if we fail, it will probably be a devastating blow to us."
Over the past decade or so, the combat effectiveness of the Arab Empire's army has been continuously increasing.
But to this day, Khalid feels that the combat effectiveness of their army is not as strong as that of the Tang Dynasty's army fifteen years ago.
The gap between the two sides is so huge, how can we still fight?
After hearing Khalid's analysis, the king of the Arab Empire was silent at first, and then said helplessly: "General Khalid, if I have a choice, I do not want to go to war with the Tang Dynasty!"
"But now, the Tang Dynasty has established a huge power in the west of our country. Now, our Arab Empire has been surrounded by their new power and the Tang Dynasty."
"Right now, their new power has not yet taken shape. The Tang Dynasty is currently cleaning up the power of aristocratic families in their country. This is the moment when their national power is at its weakest."
"If we wait until their new power is fully formed and the Tang Dynasty completely eliminates the family, will they let us go by then?"
"Definitely not! We are attacking the Tang Dynasty now, and there is still a glimmer of hope. However, if we just sit back and watch them grow and develop, there will be only a dead end!"
After listening to the king's analysis, Khalid couldn't help but sigh.
"King, I can only guarantee that I will do my best. But as for the outcome, I really can't guarantee it."
The king stood up and bowed deeply to Khalid: "Old general, I leave all this to you."
Khalid did not return the greeting, but said firmly: "This is the only way to repay your kindness."
On the second day, Khalid took command and led an army of 600,000 to launch a surprise attack on Datang.
The first place they attacked was the Persian administrative region of the Tang Dynasty.
This region was originally a country.
The country was originally destroyed by the Great Food Empire, and then attacked the Tang Dynasty.
Then they were counterattacked by the King of Shu in the Tang Dynasty. Not only did they retreat in embarrassment, they even lost the Persia they had just captured.
The area of Persia was also included in the territory of the Tang Dynasty and became the Persian County of the Tang Dynasty.
This time, since he took action against the Tang Dynasty, Khalid was prepared to capture as many areas as possible before the Tang Dynasty had time to react.
At least, Persia and the Anxi Protectorate must also be included in the bag.
Even though Khalid claimed that the Tang Dynasty was invincible when facing the king, their Arab Empire basically had no chance of winning.
In fact, in Khalid's heart, he was not convinced by Datang.
This was the only failure in his life, and it was also the worst defeat.
In his heart, he thought about regaining his place countless times.
This time, the opportunity has arrived.
This is probably his only chance.
Failure or success!
The 600,000-strong army was divided into three groups by Khalid.
The first army of 300,000 troops all attacked the Persian army of the Tang Dynasty.
For Persia County, Khalid is bound to win.
The other two groups all attacked the Parthian Protectorate.
For Persia County, Khalid is bound to win.
Therefore, Khalid personally directed this journey.
These three armies basically proceed simultaneously.
The actions on the Persian County side are only slightly ahead of schedule.
As for the military operation in Persia County, Khalid did not adopt a forceful attack.
Persia County has inherited the heroic and open ethos of the Tang Dynasty, and border trade is completely open.
Therefore, all other small towns in Persia County were ignored.
Instead, he led his army and headed straight for the Persian city.
For Khalid, the most defensive place in the entire Persian County was the city of Persia.
As long as we can capture the city of Persia, other small cities will naturally not be a problem.
His army marched very fast, reaching the point where people in small counties might be able to spot their army, but there was absolutely no time to raise an alarm.
Khalid knew very well that there was no beacon fire here in Persia County.
The only way to convey information is through people.
Khalid was confident enough that he could do it, so they couldn't deliver the message.
Khalid led the cavalry, galloping all the way, and in just half a day, they arrived ten miles away from the Persian city.
When he arrived here, Khalid ordered his vanguard to disguise themselves as merchants, sneak into the Persian city, and take the opportunity to seize the city defense.
However, when his five hundred vanguards dressed as merchants arrived at the gates of the Persian city, they were shocked to find that the gates of the Persian city were closed and they were on guard.
After Pioneer reported the news back to Khalid, Khalid was completely confused.
That's not right, it shouldn't be.
Especially after Khalid went to the city to watch Datang's defense, he felt even more strange.
Because, Khalid was sure that their attack was very confidential.
It is absolutely impossible for Datang to know in advance.
And they rushed all the way to the Persian city with unparalleled speed.
It was convenient for the Tang Dynasty. Even if he wanted to report the news, he would not be able to make it in time.
However, through the observation just now, Khalid was surprised to find out.
The defensive situation in the Persian city was definitely not a temporary decision.
Instead, it took at least half a day to prepare.
In other words, at least they started to prepare since they first entered Persia County.
But, how is this possible?
Unless, they have other ways of delivering the message.
What kind of communication method did they use?
Khalid was puzzled.
Well, in Datang, there have actually been telephones for a long time.
But the phone number has only been circulated among high-level officials.
As a remote area in the Western Region, Persia County is difficult to establish a signal for a short period of time.
It was only in the past year or two that it was laid, mainly for military use.
Khalid, on the other hand, did not know that there were already telephones in Persia County.
In fact, because Khalid had been fighting in the north and south, he probably didn't even know what the phone number was. Naturally, he couldn't figure out how the Tang Dynasty delivered the news.
What he didn't even know was that when their army first entered Persia County, the news had already been conveyed through the phone in the county seat of Persia County.
Not only did the city of Persia take precautions early, but at this time, even the Tang Emperor Li Ke in Chang'an City knew the news.
Moreover, Tang Emperor Li Ke also communicated with the ministers in a timely manner.
Response measures were formulated in a timely manner, and different orders and instructions were issued to all major counties in Persia County.
At this time, the Tang Dynasty was rapidly mobilizing its army, preparing to rush to the aid of Persian County and the Da'anxi Protectorate.
At this time, Khalid was still surprised at why Persia County responded so quickly.
He never thought that Datang's reaction was actually faster, and reinforcements had already been dispatched.
…
Since the Persian city had already been on guard, their raid was meaningless.
Khalid ordered his men to surround the Persian city.
On one side, the troops were divided into multiple groups to besiege and attack other small towns in Persia County.
They were bound to capture the entire Persian city in one fell swoop.
The entire Persian County, as well as the Great Parthian Protectorate, will become their base for attacking the Tang Dynasty.
Even if it doesn't work, they can still defend to the death.
What they were fighting was just such a time difference.
Naturally, the remaining small counties will not be spared.
As for their Arab Empire, they had always been very cruel to those captives during their campaigns in the north and south.
Their purpose is to plunder.
Not only will the captives be massacred, but their culture will also be destroyed.
They fought all the way south and north, destroying countless civilizations.
But this time, in the war with Datang.
Khalid did not want to cause more killings.
Because this time, Khalid was really not sure whether they could achieve the final victory.
And if they failed, he was afraid that Datang would retaliate and massacre them.
Therefore, even if they spread out and besieged those small counties.
Khalid also ordered the soldiers not to massacre the surrendered troops.
At the same time, Khalid believes that this must be a very difficult battle.
Because he had seen with his own eyes the combat effectiveness of the Tang Army, which was very strong.
However, the development of things was far beyond Khalid's expectation.
They did not encounter any decent resistance in other small counties in Persia County.
Wherever their army went, all the small counties and towns were turned down.
Occupying most of the city of Persia County except the city of Persia, they didn't even make a cut or shoot an arrow.
This made the Arab Empire's army, which was full of energy, feel as if they had punched cotton and had nothing to do with their strength.
The surrender of the Tang Dynasty was too easy and comfortable.
And after surrendering, they fully cooperated and did whatever they were told.
And they were given the order not to massacre the surrendered troops.
Therefore, after a war, there were no casualties on either side.
Even their commander-in-chief Khalid was very surprised after receiving the news.
How could the Tang army be so weak?
How could it be possible to lose resistance so easily?
Is this still the Tang Jun he imagined?
Has Tang Jun lost its spirit?
Are you no longer as brave as you once were?
However, Khalid always felt that something was wrong.
Since the Tang army was so cowardly, this Persian city must be no exception.
The Persian city has very tall buildings, so if it is attacked by force.
Although he brought many men and horses, it would be difficult to attack them in a short while.
If the people in Persia City would also surrender, that would be the best thing.
Next, Khalid shot the letter urging surrender into the city with arrows.
However, like a mud cow drowning in the sea, there is no news at all.
Finally, Khalid sent people in front of the city to persuade them to surrender.
Unexpectedly, the defenders on the city wall used strong bows to shoot the soldiers who tried to persuade them to surrender to death.
This made Khalid very angry.
Unexpectedly, the defenders of the Persian city were so ignorant of current affairs.
Next, Khalid issued the order to attack the city.
Although Khalid led an army of 300,000 people on this journey alone.
But the Persian city was only so big after all.
An army of 300,000 people cannot be displayed at all.
The number of people attacking the city can accommodate up to 100,000 people.
At the beginning, Khalid only made a tentative attack.
But what he didn't expect was that the Persian city's defenders counterattacked so decisively and sharply.
The first round of exploratory attacks ended with the entire army being annihilated.
The sharpness of the bows and arrows of the Tang Dynasty, the strength of the Persian city walls, and the skillful cooperation of the defenders were all beyond Khalid's expectation.
