Pyongyang itself was a port city.
Although it was a millennium before the Age of Discovery, many merchants already lived by the sea.
From Pyongyang to Silla, Baekje, or Wa, sea routes were viable and faster than land routes!
Even going from Pyongyang to Bohai Commandery saved at least half the time compared to land travel!
The collection of ships went smoothly. No one dared to resist these Tang soldiers carrying firearms!
The consequences of resistance had already been evident during the confiscation of property.
That was death!
Thus, in just two days, over a hundred ships of various sizes were collected.
Similarly, the boatmen on these ships were also forcibly recruited.
However, as Fang Er was always generous with his money, with the temptation of wealth.
These boatmen readily accepted the task.
The ships ranged from thirty meters long, with three decks.
The lower deck was for the sailors to row.
The middle deck was the main deck, and the uppermost deck served as the command center.
The smaller ones were only seven or eight meters long.
After loading the money and grain onto the ships one by one, Chai Shao led two thousand new firearms troops towards Bohai Commandery.
After seeing Chai Shao off.
Fang Er and Cheng Yaojin stood on the pier, enjoying the sea breeze.
"Brother Cheng, do you want to build a Jing Guan to play with?"
Fang Er bent down, pried an oyster from a wooden post below the pier, opened it casually, and threw the meat into his mouth.
"Hmm, it's indeed not comparable to those grown in polluted waters in later generations."
Upon hearing Fang Er's words, Cheng Yaojin's interest was immediately piqued!
"Didn't you say you were going to build the Great Wall with Goguryeo's bones?"
"Brother was still thinking if you would massacre the city."
Fang Er smiled slightly.
"The Great Wall? There's no need!"
"From now on, whoever dares to invade, we'll fight them back. What need is there for a Great Wall?"
Fang Er's tone was very calm.
But it was filled with confidence.
Cheng Yaojin was stunned.
"That's right!"
"Why build the Great Wall?"
"Just fight them back! No matter who they are!"
Whether it was Silla, Baekje, the Turkic Khaganate, or Tubo!
With firearms and cannons, it would be a blessing if they didn't bully us.
Why build the Great Wall!
"Do it! Brother, you say it, I'll listen to you!"
Cheng Yaojin, like Fang Er, pried open an oyster.
"Hmm? This thing tastes quite good!"
Fang Er chuckled.
"Eat more if you like it. Eating too much of this might even allow you to have more younger brothers for Chu Mo."
Cheng Yaojin's eyes lit up.
"Someone! Pry them out for me! Pry all of these from below and take them back!"
Thus.
The next day, Cheng Yaojin came to find Fang Er to discuss how to create the Jing Guan, with two dark circles under his eyes.
As he walked, he kept rubbing his lower back.
"Brother, the Goguryeo women are really good. Shall I send you two to try later?"
Fang Er gave him a sideways glance.
"Aren't you afraid Old Man Chai will find out and beat you?"
Cheng Yaojin looked dismissive.
"Hmph! Him? I'll let him have one hand!"
Fang Er was speechless.
"Did this guy finish the whole basket of oysters that Qian Bing pried yesterday?"
"Otherwise, it couldn't have lasted all night!"
"Brother, tell me, how do you plan to do the Jing Guan, and where will you build it?"
Cheng Yaojin sat down opposite Fang Er and asked.
"Goguryeo won't be able to cause any more trouble. As for the remaining cities, we'll deal with them later."
"The Jing Guan here will be placed outside Pyongyang city, where they buried the gunpowder before!"
"It's a way to give closure to our fallen brothers!"
"After taking down the remaining cities of Goguryeo, we'll talk about other things!"
Although Goguryeo was not large, it still had fourteen commanderies.
The Tang army relied on the power of firearms to sweep through the territory.
But afterwards, they would definitely need to mop up one by one!
This was also why Fang Er had asked Chai Shao to request more troops from Li Shimin.
Currently, besides those left to guard Shenyang Commandery and those taken by Chai Shao, and subtracting the casualties,
There were only about five thousand usable soldiers.
They absolutely dared not divide their forces to guard various cities.
If they did, they would truly be worn down to death by the resistance forces within the cities!
The location for the Jing Guan was decided.
Those in the city who were hostile to the Tang army were singled out one by one.
Along with some surrendered Goguryeo soldiers.
Under the supervision of the Heavenly Fire Army, the corpses of the Goguryeo soldiers were piled up!
With each layer, a thick layer of lime was spread to disinfect and prevent epidemics.
These people were defiant at first.
When the Jing Guan reached two meters high, some people were so terrified that their courage failed them!
By three meters high, some were so scared that they refused to move another step towards the Jing Guan!
Until finally, after all the corpses were piled together.
Over a hundred people were scared to death!
Adding bricks and mortar to the Jing Guan!
Fang Er took great care with King Rongliu's corpse!
He collected a large amount of peach gum from the city's pharmacies!
After melting it, he preserved King Rongliu's body as a specimen, placing it at the very top of the Jing Guan!
From the moment the Jing Guan was completed!
The citizens of Pyongyang city became as docile as cats when facing the Tang army!
Those who personally helped pile the Jing Guan were eventually driven to insanity by continuous nightmares!
Pyongyang city had many madmen!
The Heavenly Fire Army and the new firearms troops, armed with muskets, gained a common name.
The Devil Army from the Great Tang!
Furthermore, as some fishermen who were forced by livelihood went out to sea.
This name was passed on to Silla, Baekje, and the land of Wa!
It even reached Mohe, to the north of Goguryeo!
