The fourth volume of the Golden Light Sutra, the chapter on sacrificing one’s body, says: “Sarira is the result of the cultivation of precepts, concentration, and wisdom. It is very difficult to obtain and is the highest field of merit.” And “Sarira is the result of the immeasurable merits of the six paramitas.”

Buddha relics refer to the remains of the Buddha after cremation. Among them, bone relics are white, hair relics are black, and flesh relics are red.

As for the one currently lying in Zhang San's palm, it is clearly a bone relic.

What makes people curious is, who in Taiping County has the Buddhist Dharma to produce a relic? And who gave up such a precious treasure? Considering the sacrifice of Taiping Wei and the identity of the canonized Yiren Fayan, everything becomes very clear.

Just when Yuan Ergou reacted and was about to say something, the originally silent Zhang San suddenly held the relic and spoke in the direction of Gu Xuanyan.

"It was not suitable to visit yesterday because it was too late, but today is our second day in Taiping County. As a junior, you should go visit the one from the Wu family."

Be it skeletons or relics, Zhang San and his companions had only been in the city for two days when strange events began to occur one after another.

According to common sense, this should be a terrifying thing, so Yuan Ergou understood why Zhang San arranged for Gu Xuanyan to leave and advised her not to get involved in this mess.

The only difference from Yuan Ergou was that among all the people present, only Gu Xuanyan could see the madness in Zhang San's eyes.

Zhang San used to be in this state, but at that time he would at least use some micro-expressions to cover up the hostility in his eyes. Gu Xuanyan had already noticed this from the moment they met.

However, starting from this morning, Zhang San seemed to have changed completely.

No, that's a bit inaccurate.

It should be said that in Gu Xuanyan's eyes, his whole person became clear, without decadence, without disguise, the whole person was as pure as a pool of clear water, not allowing any haziness at all.

"It's time to pay him a visit. Oh, by the way, I made some soup in the kitchen. I'm afraid it won't taste good if it's left for too long!"

"I see."

There was no coquettishness or acting. With the help of his trumpet's memory, Zhang San himself could be considered a man who had been through many flowers without getting hurt. But to be fair, in his memory palace, no woman was as sensible as Gu Xuanyan.

It's time to increase her comfort level! ...

"Where is the sewer map for Taiping County?"

As soon as Gu Xuanyan turned around, Zhang San lost his previous warmth and warmth, and apart from a series of serious orders, there was no more laughter around.

Because of his congenital character flaws, he was difficult to get along with and even harder to warm up to. Aside from Gu Xuanyan, he and everyone else present were just colleagues.

After successfully getting rid of the influence of emotions, Zhang San's memory palace will show greater activity.

As far as the leaps in thought are concerned, it is difficult for Gu Xuanyan to maintain it with her brain power, let alone Yuan Ergou who was born into a military family.

However, he was a deputy centurion who was promoted from the front line. Although he was a little slow in connecting clues, his basic preparation work was still solid.

After hearing Zhang San's order, Yuan Ergou did not doubt it. He directly took out the oil paper map kept in the bamboo tube from the guard's hand, and then smoothed it on the wall with his hands.

"Sir, please!"

Looking at the criss-crossing network of sewers on the wall, Zhang San couldn't help but let out a creepy smile, but before anyone noticed, he quickly covered it with his hands.

To outsiders, this was just his standard thinking posture.

Memory Palace – Expand!

Taiping County has high terrain on both the east and west banks, and the Beijing-Hangzhou Grand Canal runs through the city. Almost all domestic wastewater in the East XC District is discharged into the canal. Fortunately, Taiping County has abundant rainfall, fast-flowing water, and a reasonable sewer layout.

Otherwise, considering the population size of Taiping County, the canal would have been stinking long ago, and there would be no description of "the shadow of the paddle is spreading across the ripples of the brocade harp"? However, thanks to the rigorous sewer network designed by the Ministry of Industry, Zhang San quickly found what he wanted with the help of the memory palace.

Even in the higher-lying DC area, Fuyuan Street is considered to be a prime location. If the sewers were used to kill people and dump bodies, the only possible sources would be three streets.

Baotong, Zhuqiao and Tongwei, these three streets are located at the highest places in DC District, and what’s more coincidental is that the county government is located on Zhuqiao Street.

With the existing evidence and the repeated reminders from Magistrate Fan, Zhang San was already 70% sure in his heart. However, he was used to being watertight when doing things. After all, judging from his moral integrity, he would not wrongly accuse a good person, but he would also never let a bad person go. As for the standard between good and bad, let's prove it with evidence.

Gathering his scattered thoughts, Zhang San patted Yuan Ergou on the shoulder and said.

"Prepare some raincoats and let's go down and take a look!"

"Sir, do you mean to go down here? Down here is..."

Without waiting for Yuan Ergou to answer, the surviving guard at the side could not help but speak. The young man looked quite handsome, but Zhang San could not remember his name.

At this time, Zhang San has successfully constructed the memory palace and solved the system's sequelae to a certain extent, but this does not mean that he will waste his brain cells on such a person.

Especially after saying this, I'm afraid even his appearance will disappear from Zhang San's memory.

For ordinary people, it is sometimes difficult to deliberately forget something. After all, before you deliberately do it, you have already deepened your impression of it.

However, for Zhang San who has a memory palace, this is a very easy thing to do.

…

The squeaking sounds of rats and the mixture of countless smells seem to be the true appearance of a sewer in the minds of ordinary people.

In addition to movies, this is also true in reality. If that group of people had not trampled on the peace here, the sewers in Taiping County would have lasted forever with the passage of time.

"His name is Wang Liang. He was born into a military family like me. This kid is lucky. He was the one who patrolled the city with me that day, so he escaped the murder!"

Huo, even though I was mentally prepared before, it seems that I still underestimated the extent of this situation. "

Zhang San was not interested in knowing the man's name, but Yuan Ergou's words brought back his memories.

"The sewer is the conscience of a city! ... The final veil has finally been lifted. The sewer is a shameless person, it tells everything."

After hearing Zhang San's words, Yuan Ergou was silent for a long time before he slowly said, "The person who said this is a bit compassionate."

"Hugo!"

"What kind of fruit is that? Sir, I find your speech really hard to understand."

After a rather helpless sigh, Zhang San finally started to explain: "The person who said this is called Hugo!"
