In Jianchuan City, the soldiers were still training in full swing. As for Li Ke's mansion, Li Ke, Fang Jun and Ren Yaxiang were sitting in the hall.
While reviewing the information, they discussed in a low voice.
"The information sent by the Qiang and Zhao leaders is not much different from the information obtained by the spies we sent out."
"It's just that the Tubo people have started to block traffic since the day before yesterday, so there is no new information coming."
"But the detective horses we sent to keep an eye on the three valley roads haven't sent back any news yet."
"There are only five or six days left before the date agreed between His Highness and the Tubo commander. They should be about to march."
Li Ke looked at the information and saw Li De hurried over.
"Where's Brother Chu Bi?"
"Your Highness, Cheng Changshi left early in the morning, saying he was going to arrange the battlefield."
"Then hurry up and ask him to come back. Go quickly and ask him to come over and take a look at this information."
"No!" Li De immediately turned around and walked away quickly.
At this moment, Cheng Sanlang was lying on the ground, working on the hole dug in front of him. The clothes on his body were already covered with dust.
But he didn't care about this and continued to carefully install the mines there.
Compared with grenades, mines with more charges are more concealable and more powerful.
These good treasures are naturally obtained from the Ordnance Inspection and Firearms Administration of the Tang Dynasty.
Moreover, Cheng Sanlang had almost emptied his inventory for nearly two years. As for why he wanted so many gunpowder weapons, Cheng Chubi told his father-in-law Li Shimin very plausibly at the time.
After a gunpowder weapon is produced, it will have a shelf life beyond which it will last.
Because of storage, storage, and changes in the properties of gunpowder itself, the effect will decrease, and even the gunpowder may burn but not explode.
Furthermore, the Firearms Department of the Tang Dynasty has always been a strictly confidential unit, and for the Tang Dynasty, no one knows how to use these gunpowder weapons better than himself.
Moreover, those famous generals of the Tang Dynasty seemed to have always been skeptical about gunpowder weapons. In the conflicts in the Tang and Zhou regions in the past few years, such large-scale murderous weapons had no place.
Rather than letting it rust and expire, you might as well give it to your son-in-law to use it to make great contributions, which will also let people see the power and lethality of this kind of gunpowder weapon on the battlefield.
Well, anyway, as the only gunpowder weapon expert in the Tang Dynasty, Cheng Sanlang was right no matter what he said. Even if he was wrong, there was no way for others to know.
Li Shimin also considered that this group of young people did not want to have a single army for the imperial court, but recruited young men from the Zhaoxi tribe in the central and southern areas of Jiannan Road as soldiers.
Even the two sons-in-law, Cheng Sanlang and Fang Jun, know how to train soldiers, but the problem is that training cannot be done three times, five divided by two, to produce an elite division.
In order to increase their winning rate, Li Shimin decided to let his beloved son-in-law Cheng Sanlang do it.
Cheng Sanlang was facing the main force of Tubo, who wanted to seduce him to leave Jianchuan City to fight.
Cheng Sanlang didn't want to seduce those Tubo barbarians and kill them, so the two sides led to the decisive battle of Heyangtan under the tacit understanding of mutual seduction.
But the problem is that among the descendants of the martial arts family of the Tang Dynasty, Cheng Sanlang, the most outstanding in both civil and military skills and a master of chess and cards, was the only special operations expert in the Tang Dynasty.
Well, to use a very honest word to describe it, he is very clever, full of tricks, and always able to come up with unexpected methods and tricks.
Not to mention that Tubo only came with more than 20,000 elites, even if they came twice as many, well...
It’s hard to say that Tubo will be able to win this decisive battle at Black Sheep Beach.
"Okay, how many more are there?"
After a long while, Cheng Sanlang finally got up and stretched his stiff back. He glanced around and saw that the hard-working Cheng family members were still working like farm uncles, squatting or lying on the ground.
Lay mines there.
Cheng Fa wiped the oil and sweat from his forehead and said with a sense of accomplishment on his face.
"Third Young Master, this large minefield has been almost laid out. What's more, do you need some more behind Black Sheep Beach? Anyway, there are still a lot of these mines."
"No matter how much you have, you can't waste it. Believe me, there is no way those Tibetan barbarians can pass through the other two valley roads and rush to Black Sheep Beach to stab our Highness in the back."
"Let's go, we've pretty much done it here, let's go check out the mines on Long Snake Road and Shikan Road."
As soon as Cheng Chubi turned over and jumped on his horse, he saw that Li De had already arrived, so he had to hurried back to Jianchuan City.
#####
Cheng Sanlang galloped to the north gate of Jianchuan City. At this moment, the north gate of Jianchuan Gate was already closed until Cheng Sanlang stepped forward and revealed his identity.
The heavy wooden door slowly opened, and Cheng Chubi and his entourage galloped into Jianchuan City.
With a glance, the area around the city gate had been sealed off yesterday. No one was allowed to come close, whether they were Han people, other ethnic groups, or those traders and lackeys.
After all, Cheng Sanlang has already laid mines outside. At this time, whether the caravan is coming from the north or the south, it is very likely that it will become a victim of the mine array.
Therefore, after deliberation, a notice was posted three days ago, directly and blatantly informing all the people and traders in Jianchuan City.
The Tang Dynasty and Tibet were about to start a decisive battle outside Jianchuan City. Those who wanted to leave now should leave quickly. Those Tibetan businessmen who saw the notice, or other business travelers from various ethnic groups who were about to go to Tubo, also left Jianchuan City in advance.
.
After that, the Zhaoxun coalition sent troops to the three valley roads leading to Iron Bridge City to block all the merchants and people who wanted to come south.
Of course, it is also strictly forbidden for anyone to pass through the north gate of Jianchuan City. This ensures the concealment and confidentiality of Cheng Sanlang's special operations to the greatest extent.
He hurried back to Li Ke's residence and found out that the Tibetan people were like him and had blocked Iron Bridge City. In addition, it seemed that the Tibetan elites in Iron Bridge City were also going to be brought to the battlefield.
Cheng Chubi couldn't help but his face darkened, and his eyes fell on the Qiang warrior who came to deliver the message.
"How did you get here? The three valley roads are all blocked."
"Cheng Changshi didn't know something. The villain came from Honglang Prefecture in the west. There are also rugged mountain trails between there and Jianchuan City.
Although it can't be used by horses and vehicles, there will be no problem in walking."
"...Then there should be a direct road to Iron Bridge City in your Honglang Prefecture, right?"
The Qiang warrior who came to deliver the message nodded. "Yes, the road from Honglang Prefecture to Iron Bridge City is slightly easier."
After hearing Cheng Sanlang's inquiry, Li Ke's eyes suddenly lit up.
"Brother Chu Bi, do you want to take advantage of this opportunity..."
"Of course not." Cheng Chubi shook his head directly.
