Gao Shengtai had naturally heard of Yang Huairen's name, and knew that he was a favorite of the Great Song Dynasty's official family, so naturally he would never allow him to have any accidents in Dali.

His next arrangement shows his thoughtful side.

From Lan Ruoxin's narration, Gao Shengtai judged that the group of people who kidnapped Yang Huairen must not be ordinary thieves, and those who can dig underground secret passages will definitely not be able to do it without enough financial resources and power.

The area of Dali is also relatively large, although the population is not large, but the geographical environment is complex, there are many races and forces, even if it is the lord of Dali, he does not have enough ability to govern so many forces.

But judging from the size of his influence in Dali, Gao Shengtai must be a very powerful group of people who have the ability to dig a long tunnel out of the city in Dali City, and they have paid so much, and their ambitions for interests must be very large, and they will even threaten the regime change in Dali.

Thinking about it this way, there are not many candidates left, and Gao Shengtai can't be sure who is engaged in the big conspiracy, so he immediately ordered General Xiangguo's Mansion to lead two hundred Xiangfu guards to organize the rescue of Yang Huairen, and he also went there in person.

The more than 30 entourages that Yang Huairen brought to Dali did not need to hide their identities, they had already changed their outfits, and under the command of Xiao Qi, they also joined Gao Shengtai's team to rescue Yang Huairen.

Don't look at Gao Shengtai is already over the age of sixties, but his health is surprisingly good, he did not sit in a sedan chair, but another subordinate brought a horse, he drove a horse and rode it, not like an old man in the sixtieth year at all.

The group first went to investigate the entrance of the underground secret passage in the small courtyard, and the guards of the Prime Minister's Mansion also judged that the stone door could not be chiseled in a short time, and could only find clues from the other exit of the secret passage.

Lan Ruoxin also knew that the situation in the secret passage was indeed very narrow, and the stone door was indeed thick, even if a stonemason was invited to dig the door, it would take at least a day, and after a day, I was afraid that it would be too late.

She remembered what Yang Huairen had said in the secret passage, judging from the extension direction of the secret passage, the secret passage was dug for entering and exiting the city, so not far from the east gate of Dali City, there must be another exit.

Gao Shengtai led people out of the city, and the guards guarding the city gate saw that Gao Xiangguo was coming in person, so they didn't dare to delay, and immediately opened the city gate to let everyone out of the city.

It was already half past night, the moonlight was dim, the stars were sparse, and the outside of the city was three points darker than the inside of the city, and even if the torches were lit, it was only forty or fifty steps as far as the eye could see.

A hundred steps outside the east gate, there is a large settlement, in addition, it is almost a flat fertile field, if it is determined that the other exit of the secret passage is outside the east gate, then it must be in some hidden place in this settlement area, and it will never be in the wild.

But even if the exit of the secret passage is determined in this settlement, it is not easy to find out, and there are many large and small courtyards in the settlement, and it takes a lot of time to investigate them one by one.

Moreover, if the investigation is carried out secretly, the efficiency will be too low, and all the courtyards in this settlement area will be searched, and I am afraid that the investigation will not be completed even if it is dawn.

But if it is a large-scale search with troops, firstly, Gao Shengtai will be infamous for disturbing the people late at night, and secondly, it will definitely disturb the other party, give them time to cover the exit of the secret passage, and inform the people in the secret passage.

Gao Shengtai didn't have time to weigh a lot left and right, he was more reluctant to see a county prince of the Great Song Dynasty have an accident in Dali than to be infamy, and if he and the Great Song Dynasty met in the future, then he would be a sinner in Dali.

So Gao Shengtai ordered the guards of Xiangguofu and Yang Huairen's subordinates to form a cross team, forming a team of twenty people each, a total of more than ten search teams, entering from several intersections in the settlement, regardless of the size of the courtyard, to conduct a carpet search from door to door.

Lan Ruoxin was already anxious, but she still admired Gao Shengtai's arrangement and his crisis handling ability, and this search method may be the best way.

Even if the people who kidnapped Yang Huairen and Tie Xiangyu knew that someone was searching for them outside, they couldn't escape together, and there was a fertile field outside the settlement, and anyone who escaped would definitely not be able to escape the attention of the search team.

If they can't escape, they can only hide inside the secret passage, although the fanfare search will definitely alarm them, but this may also make them use Yang Huairen as a bargaining chip to escape, so as not to hurt him.

The vigorous search operation began, and more than a dozen search teams began to search from the outside to the inside, door to door, and in the middle of the night, the residents and people in the settlement area were disturbed, and naturally they were a little angry, and the sound of insults and barking dogs came from all directions.

The guards of Xiangguo's Mansion were not rude, although they broke into the people's homes, they did not bully the people, but showed their majesty, informing them that there was a group of thieves hiding in this settlement, and Gao Xiangguo ordered a door-to-door search and asked them to cooperate.

Naturally, ordinary people did not dare to disobey, and hid aside with their families, allowing the search team to carefully inspect their courtyards.

The guards also seem to be very experienced in finding underground chambers, except for places such as the mouth of a well, which can obviously be used as an entrance to a secret passage, half of the people in each team have found wooden sticks that are arm thick, and use them to strike the ground, and judge whether there is a hole in the ground from the sound of knocking.

This kind of search is also very careful, the guards do not let go of almost every foot of the ground, whether indoor or outdoor, and search every courtyard tightly.

At first, there were small courtyards on the edge of the settlement, which were the least suspicious and easier to search, but the deeper you went into the settlement, more and more larger mansions appeared.

Such a large mansion is not easy to search, and it takes a lot of time to search step by step, and most of the owners of these mansions are powerful people in the city, and they don't pay attention to the search team at all.

If it weren't for Gao Shengtai's personal appearance, I'm afraid that people's doors wouldn't be able to enter, even if they can break in, big families also have caretakers, and I don't know what kind of trouble will be caused.

Time passed little by little, and the search went smoothly halfway, but there was still no secret passage to be found, but it was found that many people had dug underground warehouses with furniture, and in addition to money, they also searched for many other shady things.

Lan Ruoxin's heart became more and more anxious, every time she found the basement, she was full of hope, but every time she was disappointed, her mind became more and more chaotic, more and more impatient, and the tears in her eyes couldn't help but overflow again.

At this moment, Brother Tianba suddenly asked thoughtfully, "You guys, have you smelled anything?" ”
