Su Yu nodded, and then said: "There is nothing to do today, everyone should go back and do their own thing."

"yes!"

Everyone responded, and then walked out of Qianhu Mansion and walked towards their own Baihu Mansion.

After everyone left, Su Yu walked into his room, then took out a pair of tonics and started boiling them.

"I still have three sets of tonics on hand, which should allow me to gain three attributes."

"As my cultivation in the Yu Leap realm gets higher and higher, my physical strength will also increase. When I reach the Hidden Dragon realm, it may not be that easy for me to gain attribute points again."

"Before continuing to improve your cultivation, you can first increase the proficiency of Jing Zhongyue's martial arts to the limit."

"I'm quite curious. When this martial art is practiced to the limit, what kind of amazing changes will occur? Its power should barely reach the level of heaven, right?"

Su Yu looked at the burning firestone in front of him and murmured in a low voice.

He had already bought all the thousand-year-old tonics in Wanbao Tower in Tai'an City.

Now if you want to buy thousand-year-old medicinal materials again, you can only go to other large cities with Wanbao Tower to buy them.

Su Yu's plan was to buy all the thousand-year tonics in Tianyuan City's Wanbao Tower on the day he went to Tianyuan City to hunt Master Xia.

"Currently, I still have 2.4 million yuan crystals in my hand, which can probably be used to purchase twenty-four sets of tonics. Just to upgrade Jing Zhongyue's martial arts to the limit, twelve more attributes are needed."

"The remaining twelve tonics are not enough to get the attribute points I need to advance to the Hidden Dragon Realm."

Su Yu couldn't help but sigh in his heart.

As one's cultivation level gets higher and higher, money seems to become less and less worth spending.

The road to making money is long.

And now that he has already reached the leaping realm, there is no way he can continue to go to the animal trap to collect the wool of his future fourth brother-in-law.

But when talking about Tianyuan City and his party, Su Yu immediately thought of marrow-eating leeches.

Although he had successfully used a black pill several times before to get the information he wanted out of the captured people.

But once it doesn't work, you will definitely need a real marrow-eating leech to get the information you want.

For example, he plans to go to Tianyuan City in a few days, kill Lord Xia, and follow the clues to find out who is behind him, Lord Angel.

If he succeeds in capturing Master Xia, he will inevitably need to be tortured before he can figure out how to contact Master Xia.

As a warrior in the Yu Leap Realm, Mr. Xia's ability to withstand torture must be much stronger than that of the Twenty-Four Solar Terms.

When I participated in the arrest of Lord Haru, marrow-eating leeches were used in subsequent interrogations.

In other words, if he later wants to pry out the method of contacting Master Sun from Master Xia, he can only rely on real marrow-eating leeches.

The marrow-eating leech was far away in the Western Zhou Dynasty, so he had to get the real marrow-eating leech before he captured Master Xia.

If you think about spending money to buy it from the Western Zhou Dynasty and then sending it to Tai'an City, it will take at least ten days and a half.

Naturally, he couldn't wait for such a long time.

Moreover, after catching Mr. Xia, he will definitely be interrogated immediately.

Once the time drags on for a long time, the angels above are very likely to get wind of it in advance, which will delay the fighter plane.

Later, if you want to rely on the contact information in Master Xia's hand to fish out Master Sun, it will not be that easy.

Thinking of this, Su Yu couldn't help but think of Lu Ze.

That guy may still have some stock of marrow-eating leeches.

On the surface, I don't know anything about marrow-eating leeches.

But he can make some innuendoes and first ask him if he has any good way to torture the prisoner.

"Ding Yang, go and call Mr. Lu and Mr. Lin over. I have something to do with them."

Su Yu came to his study and gave instructions to his personal guard Ding Yang who was guarding outside.

"yes."

When Ding Yang heard this, he immediately walked out of Qianhu Mansion quickly.

After a while, Lu Ze and Lin Canglan walked into Su Yu's study together.

"grown ups."

Lu Ze and Lin Canglan clasped their fists together.

"Um."

Su Yu closed the book in front of him, then looked at the two of them, and said with a smile: "Brother Lu, Brother Lin, it has been a while since you were promoted to Baihu, but are you still adapting to the work of Master Baihu?"

Hearing Su Yu's words, Lu Ze and Lin Canglan both smiled and nodded.

"It all depends on the cultivation of adults, everything is quite adaptable." Lu Ze said with a smile.

Su Yu climbed from a Zhenwu guard to their heads. This feeling made both of them feel a little sad.

They never imagined that Su Yu would one day become their immediate boss.

And if this situation is nothing unexpected, it may be the case in the next few decades.

They don't think that they will have the opportunity to enter the Yuyue Realm in the future.

In other words, in the future, they are very likely to stay at the position of 100 households until the day they retire.

"Just get used to it."

Su Yu nodded and said with a smile: "I joined the Zhenwu Division in a very long time. It has only been half a year. There are still many things to learn."

"I have come to see you because I have something to ask you."

Hearing Su Yu's words, Lu Ze and Lin Canglan were both startled.

"Sir, if you have any questions, just ask." Lin Canglan said respectfully.

"That's right."

Su Yu chuckled and said: "Just some time ago, I took Hong Heng and three hundred households to Tianxuan City to investigate the matter of someone making a private crossbow. I believe you two still remember it, right?"

Lu Ze and Lin Canglan both nodded and waited quietly for Su Yu's next words.

Su Yu continued: "In Tianxuan City, in addition to investigating the case of privately manufacturing bows and crossbows, there was also an incident in which Yuyue Realm warriors fought in Tianxuan City."

"I didn't tell you before because I was worried that the news would leak out."

"But now that the dust has settled, it doesn't matter if I talk to you."

"One of the two parties in the battle came from the Gate of Hell."

"Hell Gate?"

Both Lu Ze and Lin Canglan's pupils shrank.

Regarding the Zhenwu Division's previous deeds of annihilating the Yama Palace in Jingzhou, the entire Zhenwu Division has already spread the news. Naturally, they also know that Tianxuan City was once the stronghold of the Yama Palace.

Lu Ze immediately thought of the crux of the problem and couldn't help but ask: "Sir, this Hell Gate has chosen to build the Yama Palace in Tianxuan City again?"

"good."

Su Yu nodded and said with a smile: "At that time, this was just a guess by me. It was not certain whether the Hell Gate would rebuild the Yama Palace in Tianxuan City."

"But obviously Hell Gate thinks that the more dangerous the place, the safer it will be. The Zhenwu Division has just uprooted the Yama Palace in Tianxuan City. It would never have occurred to them that the Yama Palace would be rebuilt in Tianxuan City."

"After I came back, I told Lord Wei about the matter, and Lord Wei reported the matter to His Majesty."

"His Majesty ordered the four commanders to rush to Tianxuan City to conduct a secret investigation and successfully found the location of the newly built stronghold of Yama Luodian."

"Under the siege of four commanders, the Ghost Emperor suffered severe injuries and broke out to escape."

"Most of the other members of Yama Hall were executed, and a small number were captured alive."

Having said this, Su Yu paused, then changed the topic and said, "I have come to see you two because I want to ask if there is any strategy that can be miraculous in interrogating these Hell Gate assassins."

"You two must also know that these killer organizations have undergone rigorous training, and ordinary torture cannot pry their mouths open."

"So there must be faster interrogation methods that can pry useful information out of their mouths. This is very important for the Zhenwu Division to uproot the Hell Gate from all over Kyushu."

After hearing Su Yu's words, Lu Ze and Lin Canglan couldn't help but look at each other, and then they thought of marrow-eating leeches at the same time.

"Sir, have you heard of a way that bad guys tortured prisoners in the Western Zhou Dynasty?" Lu Ze couldn't help but ask.

Su Yu pretended to be confused and asked: "A way for bad people to torture prisoners?"

"good."

Lu Ze nodded, and then said: "There is a kind of insect called the marrow-eating leech in the southern border of the Western Zhou Dynasty. It likes to eat bone marrow. Once it enters the human body, it will eat the bone marrow of the human body. When bad people discovered this, they used the marrow-eating leech.

Included as a method of torture for important prisoners."

"However, these marrow-eating leeches are also very expensive. Each one requires at least five thousand yuan crystals. It can only be used to torture one prisoner. I have not heard of anyone who can withstand the torture of a marrow-eating leech."

Su Yu's eyes couldn't help but light up, and then asked: "How did you get this marrow-eating leech? There is currently an important prisoner in Tianxuan City, and the Zhenwu Department urgently needs to pry out useful information from him."

Lu Ze said: "Sir, if you want to get marrow-eating leeches at the moment, you can only send a Qianli Falcon to Yunzhou Zhenwu Division and ask the Zhenwu Division over there to arrange for someone to buy it."

Su Yu frowned slightly and said, "If you come and go like this, you will lose time. Brother Lu, is there anyone in Tai'an City who has marrow-eating leeches?"
