Shi Sheng still couldn't believe it, and whispered, "But...... How difficult is it to attack a city? We have only been trapped in the cave for four years, but can the Buddha Kingdom really capture tens of thousands of cities above the county level in just four years?"

Xiao Lanyu looked directly at Shi Sheng with both eyes, and said in a low voice: "Back then, the god of war Xue Xiangnan quelled the rebellion of the three kings and captured 1,300 counties in the three states, how long did it take?"

Shi Sheng's heart sank, and he said, "One month." Then he said: "But that's different, the rebels of the three kings, the army is uncertain, and they flee or surrender when they encounter a setback, and our royal division meets the army of the Buddha country, how can they flee in a battle and ignore the people in the rear?"

Xiao Lanyu sighed lightly and said, "Ah Sheng, take a closer look at the city gate." When Shi Sheng heard this, he turned his head to look at Qingshi County, when the sky was dark and far away, Shi Sheng looked carefully for a while, only to see the traces on the city gate, and couldn't help but be taken aback, and said: "That's ...... Traces of siege artillery!"

Xiao Lanyu nodded and said, "Yes, it is indeed the traces of siege artillery, you also know that the county is protected by the imperial city enchantment, and the siege artillery can only bombard the city gate after breaking through the imperial city enchantment." When Shi Sheng heard this, his face sank like water for a while, and he frowned silently.

Every city above the county level is built by the ancient powerful people with countless efforts, and the city walls are all made of corundum, which is impregnable, and there is a large enchantment outside the city to protect it from the attack of resentful spirits and demon beasts.

The barrier outside the city to resist demon beasts and resentful spirits is called the "Shenluo Enchantment", which can only resist the attacks of demon beasts and resentful spirits, but it will not hinder the entry and exit of humans, nor will it resist the attacks of humans, that is. The Shinra Barrier is ineffective against humans.

However, cities above the county level have two barriers, the outer barrier is the Shenluo barrier, and the inner barrier is called the "Imperial City Barrier", the Imperial City Barrier is not set by the ancient powers, but by the founding fathers of each country, which can resist the attack of human beings and prevent human beings from entering and exiting, such as the Imperial City Barrier in Qingshi County, which is the founding emperor of the Blue Mountain Kingdom. Order the Enchantment Master to set up. It has been more than a thousand years now.

The Shenluo Barrier is permanent and cannot be closed, while the Imperial City Barrier can be opened and closed, and usually the Imperial City Barrier is closed only in special circumstances. The Imperial City Barrier will be opened. For example, the war between the two countries and the invasion of foreign enemies. Or if there is a national prisoner in the city who wants to flee, then the Imperial City Barrier will be opened.

Back then, Shi Sheng was in the county town of Sanhe and killed Luo Qiyun. Committed a national crime, at that time, the county was a battalion and sent a message with a beacon fire, opening the imperial city barrier to prevent Shi Sheng from escaping from Sanhe County, and at the same time, it also harmed Huoyun Lao Zu and others, who could not escape beyond the city wall, and could only escape from Sanhe City by capturing the city gate first, because there was no imperial city barrier at the city gate.

The Imperial City Barrier is very powerful, relying only on manpower, it is extremely difficult to break, usually the two countries are at war, and the besieging party will carry a siege tool, which is the siege artillery.

The siege cannon is made of a special source energy technique, which has a very strong destructive power for the Imperial City Enchantment, the defender will try to destroy the siege artillery, and the besieging side will try their best to protect the siege artillery, so the survival of the siege cannon is usually the key to the victory or defeat of the siege battle.

The operation of the Imperial City Enchantment and the siege cannon requires a special energy source, called "Magic Energy Crystal", the Magic Energy Crystal is very precious, and it is also very rare, it can be said that it is hard to find, once the Magic Energy Crystal is exhausted, the Imperial City Barrier will temporarily disappear, and the siege cannon will not be able to operate, so many siege battles, in essence, are actually wars of attrition.

The nature of the magic energy crystal is strange, similar to a life form, and it cannot be included in the boundary stone, so the transportation and reserve of the magic energy crystal is also the key to the victory or defeat of the war, which is also the reason why almost every city above the county level has a river running through it, and its purpose is to facilitate the transportation of magic energy crystals.

In almost all siege battles, the besieging side will bring a lot of enchantment divisions to set up the enchantment at the first time and block the space to prevent the operation of the teleportation array in the city and prevent the defenders from transferring or supporting with the teleportation array, these are common sense of war, Xiao Lanyu and Shi Sheng are very well understood.

To put it bluntly, most of the time, siege warfare is a war of attrition, so Shi Sheng was so surprised, it was hard to believe that the Buddha Kingdom could capture tens of thousands of cities above the county level in just four years.

However, the facts are in front of us, because Shi Sheng does not believe it, the traces caused by the siege cannon are unique and clear, and they are placed on the gate of Qingshi County, which is the most powerful evidence.

War is cruel, it is always the people who suffer, the army of the Buddha country has come to Qingshi County, Youzhou must have fallen, maybe Qingzhou has fallen! This is what Shi Sheng does not want to see, because the war is spreading, there will be a lot of life, I don't know how many people will die!

After a long time, Shi Shengfang whispered: "Lan Yu, let's find a place to hide for a night, and then find a chance to sneak into the city tomorrow, we must find out, what has happened in the past four years?" Xiao Lanyu nodded in agreement, and the two quietly retreated, to a small forest a few miles away, and they would spend the night.

Early the next morning, Shi Sheng and Xiao Lanyu came to the outside of Qingshi County, restrained their breath, hid behind the dirt slope, and observed the situation.

At the end of the day, there are soldiers one after another to walk up to the city tower, one by one red flags are inserted on the city wall, each red flag center, there is a golden "swastika" word, Shi Sheng and Xiao Lanyu both recognize, this is the military flag of the Buddha country, and the soldiers who walked up to the city tower, all are bald, wearing monk's clothes and armor, at a glance is the Buddhist soldiers, but also the "bald dog" in the mouth of the people of the blue country.

Shi Sheng couldn't help sighing, now he had nothing to doubt, Qingshi County had indeed been captured by the Buddhist army.

Xiao Lanyu groaned slightly, and said in a low voice: "It's strange, since the Buddha army has captured Qingshi City, why didn't the military flag be planted yesterday?

Hearing Xiao Lanyu say this, Shi Sheng also felt strange and said, "Could it be that you say...... Did the Buddha army capture Bluestone City yesterday?"

Xiao Lanyu shook his head and said: "Impossible, the siege cannon weighs millions of catties, or even tens of millions of catties, and where it passes, it must leave extremely deep ruts, you see that there are no traces of ruts outside the city, indicating that the ruts have been cleaned by the soldiers of the Buddha country." ”

"The fact that the Buddhist army is willing to spend time and manpower to clean the ruts means that they have firmly occupied the city of Bluestone, and the city has become a rear stronghold that they will not easily lose, that is...... The cities around Qingshi County must have been captured by the Buddhist army. (To be continued......)
