Three Kingdoms: I choose Xiao Qiao and Da Qiao, why are you crying, Diao Chan?

Chapter 509 Xu Huang Arrives! (Thanks to Zhaixingloudao for the monthly ticket support from Danweijungu brothers~)
The next day.

Huangfu Song ordered the remaining 81,000 troops to leave 11,000 men to dig in secret.

Another 70,000 people continued to launch a fierce attack on Guzang City!
Facing the attack of 70,000 enemy troops, Wei Yan did not dare to save too much gunpowder.

But in just two days, the stock of gunpowder bottles was reduced to only a quarter of the original amount.

Fortunately, by the end of the second day, the enemy had lost another 5,000 men, while they had lost more than 1,000 men.

Time unknowingly came to the third day.

Both the attackers and defenders looked exhausted.

Wei Yan, with a pair of subtle dark circles under his eyes, said to Guo Jia beside him:

“The fierce attack of 70,000 troops is truly terrifying!
"I don't know how many days we can hold out..."

Guo Jia looked at Wei Yan's tired expression and advised with a smile:

"Let General Zhao Yun guard the city today.

"If Wen Chang collapses from exhaustion as the commander-in-chief, it will have a great impact on the morale of our army."

Wei Yan refused without hesitation:

"At least let this general survive today.

“But you can let Zilong come up to accompany me, and let him see how I defend the city.

"This way, he will be more relaxed when we let him guard the city tomorrow."

Guo Jia hummed, then looked at the enemy troops who were preparing to attack, and frowned unconsciously.

Seeing the worry on Guo Jia's face, Wei Yan smiled and comforted him:

“Don’t worry, Fengxiao, the enemy’s losses are several times greater than ours!
"If they keep fighting, they will be the ones who lose in the end!"

Guo Jia shook his head:

“This is exactly what I’m worried about.

“The enemy must have known that if they continued to fight like this, even if they attacked the city walls, it would be difficult to defeat us.

"But the enemy still launched such a high-intensity attack...

“At first glance it seems like they are in a hurry to achieve results, but to me, it seems like they are hiding something.

"But what are you hiding?"

Guo Jia's eyes swept across the enemy camp.

Suddenly I noticed that when the enemy was concentrating their soldiers, they would deliberately avoid certain positions.

In addition, he noticed that there seemed to be a lot of inconspicuous mounds behind the enemy camp...

Looking at these piles of earth, Guo Jia twirled his fingers slightly.

However, after a moment, he suddenly thought of something and his face suddenly changed!
Then he looked again at the place that the enemy soldiers deliberately avoided.

Faintly, there was a route leading directly to their city!
Seeing this scene, Guo Jia immediately confirmed his guess and gradually relaxed.

He joked to Wei Yan who was looking puzzled:
"Wen Chang, tell me, if the enemy suddenly appeared in our city, would you be scared?"

Wei Yan looked at Guo Jia as if he were a fool:

“Feng Xiao is such a joke, how could the enemy suddenly appear in the city?

"Could it be possible that they can fly and hide underground?!"

Guo Jia said happily:

"Flying is of course impossible, but burrowing underground... that's hard to say."

If Wei Yan still couldn't react after being reminded to this point, he would be unworthy of his status as a famous general.

Wei Yan's tiger eyes widened little by little, with a look of disbelief on his face:

"Feng Xiao means that the enemy might dig a tunnel into the city?!"

Mozi, the founder of Mohism, mentioned in "Mozi: Preparing for Caves" how to prevent the enemy from digging tunnels to attack the city.

Therefore, although digging tunnels to attack the city requires a lot of manpower, it is not impossible!
Guo Jia nodded approvingly:
"Wen Chang is indeed a brave and resourceful general that the lord trusts!

"Gu Zang City is close to the desert, the ground is dry, and there is almost no water in the moat." Therefore, the soil under Gu Zang City is relatively dry and solid, and it is not prone to landslides when used to dig tunnels.

“And every time the enemy attacked the city, they would always expose a boundary in the middle.

"If my guess is correct, this passage is the route the enemy took to dig tunnels!

"If the soldiers rashly stepped on it, it would probably cause the tunnel dug below to collapse.

"I just don't know where the enemy's tunnel has reached..."

Seeing Guo Jia's unhurried look, Wei Yan became anxious instead and said quickly:
"The enemy may dig into the city at any time, we must make preparations in advance!

"But the enemy has already begun to attack the city. Military Advisor, please go with Zilong to make preparations so that I can defend the city with peace of mind!"

Guo Jia patted Wei Yan on the shoulder and said:
“As the saying goes, it is better to unblock than to block.

"The enemy has worked so hard to dig their way into the city. If we don't prepare some generous gifts, won't we look like civet cats?"

Listening to Guo Jia imitating the strange accent that his master had once spoken, Wei Yan smiled helplessly:
“It seems that the enemy can have a good drink.

"Everything will be left to Feng Xiao to handle."

Guo Jia responded and immediately went down the city wall.

At this moment, Zhao Yun was directing the soldiers to transport various supplies for defending the city to the top of the city wall.

At this moment, he suddenly caught a glimpse of Guo Jia walking towards him.

Guo Jia whispered something in his ear, and Zhao Yun immediately looked stunned.

Then, with a serious look on his face, he followed Guo Jia towards the inner wall of the city wall.

Zhao Yun stared at the corner of the wall and asked solemnly:

"Military advisor, are you sure the enemy will enter the city from here?"

Guo Jia nodded slightly:

“The enemy attacked for two days just to attract our attention.

"I noticed the enemy's abnormality on the first day, but it was not until today that I finally figured out their intentions.

"Fortunately, although it's a little late, it's still in time."

As Guo Jia spoke, he ordered his men to bring in dozens of empty cans and stack them at the base of the wall.

Then put your ear to the surface of the jar and listen.

Of course, because the enemy outside the city was attacking the city at this moment, he could only hear countless messy footsteps coming from far away!
But it turns out that the pottery jar monitoring method recorded by Mozi is effective to a certain extent.

Next, they just need to wait until night time so that they can more effectively hear whether there are any enemy digging noises beneath the city where they are.

"Calculating the time, if not tonight, then tomorrow night, the enemy will definitely dig out from a hidden place nearby..."

As he spoke, Guo Jia looked around and soon noticed the corners on both sides of the city.

Soldiers generally do not deliberately approach these two places.

Moreover, there were some wood and other things piled up in these two places, which actually served as a certain concealment...

Guo Jia immediately ordered the idle soldiers to move the wood away.

Looking at the slightly damp ground, a "nuclear-kind" smile appeared on the corner of his mouth...

That night.

Dong Cheng, covered in mud, crawled out of the tunnel and said to Liu Xie with surprise:
"Your Majesty! We have successfully dug into the enemy's city and can dig upwards at any time!
"Should we act tonight or tomorrow night?"

Liu Xie pondered and said:

"Let's take action tomorrow night. The army has been attacking for three consecutive days and is already quite tired. We can take a short rest tomorrow.

"And according to the scouts, Xu Huang's army is already on the way.

“I heard that the losses were quite severe, with nearly half of the troops lost!
“But more than 30,000 soldiers managed to arrive.

"After we meet up with them tomorrow, we will launch a surprise attack through the tunnel in the second half of the night!"
