Wen Ping, this name was heard in Wen Shang's mouth, and at first Fu Quan only thought that he had heard it wrong, after all, how could he find a random officer to help, and he could happen to catch his son is a famous general in later generations, wouldn't this luck be the rhythm of buying a lottery ticket and winning the jackpot at will?

It's just that, obviously, Fu Quan underestimated the unfortunate arrangement of fate, and after repeated confirmation, Fu Quan determined that this Wen Shang must be the father of the later Cao Wei Grand Prize Wenpin. After all, the two are also from Wanxian County, Nanyang County, and according to Wen Shang, Wen Ping is only ten years old now, and according to his age, he is almost in line with the age of Wen Ping

It seems that this article is still not able to be treated according to his original attitude of coping with things, and if he doesn't grasp this potential stock well, Fuquan will definitely regret it for life. Of course, for Wen Ping's sudden intrusion into life, Fu Quan can only say that fate will always surprise you from time to time, but it is difficult for you to grasp his pulse.

There is no gossip, Wen Shang arranged all the matters, then said goodbye and left, although he promised to help Fu Quan, but before he got the real reward for the promotion of the official position, of course he would not really stay by Fu Quan's side wholeheartedly, in case Fu Quan sold him, he helped Fu Quan, and Fu Quan did not fulfill his promise, he was not going to be pitted to death?

Therefore, Wen Shang still wants to return to the camp as soon as possible, at least now except for the Yizhou soldiers and horses in Fuquan, no one knows that he came to help, and he even deceived his old friend of the deputy Sima, but the reason he used to leave the camp was that he had been ordered to go out of the camp to carry out important things, so he came out. Therefore, as long as he is not absent for too long and returns to the camp quickly, it will be difficult for others to find out.

Regarding Wen Shang's idea of leaving so early, Fu Quan naturally understood in his heart, and he didn't force him to stay, after all, if after the guidance of a special person, these soldiers under his command couldn't even dig tunnels back and forth, then Fu Quan might as well let them come by themselves.

And at this time, it is not very useful to stay in the woods, it is better to let him go back to the camp, on the one hand, let him be relieved, on the other hand, let him understand that he will not harm him, I believe that Wen Shang himself also understands that Fu Quan has long seen through his intentions, but he has not exposed it, everything is Fu Quan's preparation for winning Wen Shang's potential, Fu Quan believes that if this continues, Wen Shang will eventually return to his heart and trust himself.

Not long after, in this remote forest, the Ba County soldiers under Fu Quan's command were quietly digging a tunnel leading directly to the city wall of Exian County under the personal leadership of the officers of various departments.

Digging a tunnel that is more than 20 miles long underground, and to ensure that the tunnel cannot be deviated during the excavation process, is undoubtedly a huge and very delicate civil engineering. This project is extremely difficult for ordinary people, Fu Quan thought that digging tunnels as long as they dug in the direction was easy, but several accidents occurred in the middle of the way, but he felt the difficulties.

The waterways around the county seat of Exian County are vertical and horizontal, and there are not many hills around the county, and the terrain is mostly plain, so there is a lot of water in the ground, which adds a lot of difficulties to the excavation work. Moreover, it is impossible for the water in the tunnel to be drained, so all the Han soldiers who participated in the excavation inside were almost knee-drenched. Fortunately, the soldiers under the command of Fuquan are all barbarians who have been accustomed to walking in the mountains and forests since childhood, and they are also used to walking the mountains and forests and waterways, but there are not too many complaints, and although there is water on the ground, it is not a silt place, and the soil of yellow mud is quite strong, and several reasons are added, so that the excavation work has to continue.

However, these are not bad, what really worries Fu Quan is that the tunnel is dug crookedly, because after all, it is the first time to dig the tunnel, and the soldiers under his command naturally cannot have the magical experience of pointing where to dig, and there are several mistakes in the middle, wasting a lot of time.

Finally, after paying the price of several tunnels and re-excavation, the Han soldiers finally dug the tunnels to three miles outside the city of Exian four days later. During this period, I was lucky that there was no accident of tunnel collapse, but it made Fu Quan sigh that his luck these days is really good, although the time took more than expected, but after all, there were no more casualties, which can be regarded as gratifying.

Of course, the reason why the excavation was stopped three miles outside the county seat of Exian County was not that the tunnel could not be dug, but that the defenders of the county seat of Exian County were a little abnormal, because the scouts who were sent by Fuquan to monitor the head of Exian County every day came with news, and the soldiers in the head of Exian County seemed to have installed a lot of listening urns, which made Fuquan's face gloomy at once, but he didn't expect to be discovered.

The so-called listening urn is actually the most primitive eavesdropping device in ancient times. It is a jar with a small mouth and a large abdomen, and when it is used, the urn is buried in the ground, and a thin layer of leather is covered on the mouth of the urn, and when there is a need to detect, the ear is leaned on it, and the surrounding movement is "heard". If necessary, professional intelligence personnel are directly asked to sit in the urn and listen to the sound, which is called "poppy listening". Of course, in order to reduce intelligence errors, the ancients often trained blind people to perform the task of "listening", because blind people are not good at seeing but their hearing is often super strong, and the movement within a radius of dozens of miles can be heard through the listening urn. There is a detailed explanation of the manufacturing and use of the listening urn in "Mozi Beixue", and the listening urn was the most magical in ancient warfare, when dealing with tunnel siege warfare.

Later, when he found out the reason for being discovered by the rebels, Fu Quan realized that he was careless, and he ignored that the rebels were not stupid, and allowed the Han soldiers to besiege the city without doing anything. Although the rebels may not be able to defeat the Han army in the field because of problems such as equipment and numbers, so they have been cowering in the county to defend, it does not mean that they do not send people to reconnoiter the Han army, after all, it may be difficult for a team of men and horses to come out of the besieged Exian county, but it is very easy to separate a few people, just need to be cautious, and it is not difficult to come out to reconnoiter some intelligence.

Originally, in order not to be discovered by the rebels in the city of Exian County, when the Banyu barbarians under Fuquan dug the tunnel, the soil dug up was wrapped in clothes and other things by Fuquan's order, and then transported to the far side of the forest to fill it up, instead of being piled directly on the tunnel entrance, because he was afraid that the smoke and dust raised in the woods would make the rebels in the city suspicious.

At the same time, the wood used to support the tunnel was also transported into the tunnel under the cover of the soldiers under his command, in order to cover his own scheme, Fu Quan did not cut wood in this wood, after all, if he really wanted to do this, didn't he take the initiative to tell the defenders of Exian County, is there something abnormal in this forest? Fu Quan wouldn't do this kind of stupid thing of taking the initiative to give away people's heads and help the opponent upgrade to become a god, if he really wants to do that, how is it different from sending his life?

However, despite Fuquan's caution, the scouts sent by the rebels to reconnoiter outside the woods discovered their true intentions and eventually leaked the secret, and Fuquan had many problems in front of him.
