After careful understanding, Zhang Haoyu finally found a little clue, and went the opposite way, specifically investigating those disciples who did their own work carefully, and finally let him find a flaw.

It seems that these disciples are meticulous and dedicated to doing their own work, but this superficial phenomenon of knowledge, in private, there is a person who is always investigating all kinds of information inside the sect, and then transmits it to the outside without anyone knowing, Zhang Haoyu finally let him catch him after several days with him, a disciple who showed his flaws.

On a dark and windy night, this flawed disciple quietly left the Heavenly Sword Sect alone, went to a city at the foot of the Heavenly Sword Sect, and then entered a very inconspicuous inn, stayed for a while and left, and then returned straight to the Heavenly Sword Sect, this disciple probably thought that no one had seen all this, but he miscalculated, Zhang Haoyu had been following behind this disciple and witnessed all this.

Heavenly Sword Sect, the place of law enforcement disciples.

"Knock knock!" kept ringing at the door of one of the disciples in the middle of the night.

"Who? It's so late, I don't know if people are going to rest?" This disciple is called Wang Sicheng, and although he is scolding, he still gets up and goes to open the door.

When he walked to the door, he shouted to the people outside the door again: "Who? If you don't say it, I won't open the door, it's a big night, at this point, isn't this disturbing people's dreams?"

"Check the water meter!" A heavy voice came from outside the door, the person who knocked on the door in the middle of the night was naturally Zhang Haoyu, and the reason for checking the water meter was what he thought of temporarily, so he said it casually.

The door opened a crack, Wang Sicheng cautiously looked at who the people outside were, and before he could see clearly, the door was kicked open by Zhang Haoyu.

Wang Sicheng fell to the ground, no matter who came, he scolded in his mouth: "I'll go, that rabbit cub, if you don't make this matter clear today, I'll invite you to the law enforcement team for tea!"

As soon as he finished speaking, after seeing clearly that the person who came was Zhang Haoyu with the help of the faint light, Wang Sicheng suddenly stopped talking, he still knew very well who Zhang Haoyu was, and there was no way to take Zhang Haoyu himself.

"Haha, it turned out to be Senior Brother Zhang? I don't know if it's so late, what is the matter with you coming here?" Wang Sicheng retracted the careful thoughts in his heart, and said to Zhang Haoyu with a smile on his face.

Zhang Haoyu looked at Wang Sicheng with a smile on his face, he really wanted to see how far this Wang Sicheng could act, so after thinking about it, he said to Wang Sicheng: "Senior Brother Wang, there is actually a very important thing to come to the door today!"

Wang Sicheng hurriedly poured the tea, and then asked Zhang Haoyu to sit down before asking: "I don't know what important things Senior Brother Zhang has, if Senior Brother can help, there will be absolutely no problem!"

Although he said this, Wang Sicheng hated Zhang Haoyu in his heart, it was very tiring to send the news so late, but now he was just about to lie down and was woken up, this kind of taste will not be so comfortable on the body across the water!

Looking at Wang Sicheng, who was still pretending to know nothing, Zhang Haoyu felt funny in his heart, but he still held back a smile and said to Wang Sicheng: "Liu Wan'er, Senior Sister Liu, Senior Brother should know, right?"

Wang Sicheng thought for a while and said, "I know, I have a little friendship, but I don't know much about it!" Wang Sicheng naturally knows who Liu Wan'er is, and he also knows Liu Wan'er's identity, and he is also doing things for a certain race, but Liu Wan'er's status in the Heavenly Sword Sect is higher than him, and she belongs to the series of true disciples, so she doesn't have much intersection with him.

Zhang Haoyu grinned, and then said: "It's good to know, this saves me a lot of things, Senior Sister Liu suddenly disappeared some time ago, and I have a good relationship with her, so I thought about borrowing Senior Brother Zhang's identity in the law enforcement team to see if I can help me find out some news and see where she went in the end!"

Zhang Haoyu smiled and said to Wang Sicheng in front of him, it's not very good to take the liberty of doing it directly, in case it is like Liu Wan'er and Yang Yu, so the news will be completely broken, so Zhang Haoyu plans to put a long line to catch a big fish, this time using this Wang Sicheng who is showing his horse's feet to find out all the demon spies in the Heavenly Sword Sect in one fell swoop, and not let anyone betray the human race.

Wang Sicheng pondered for a moment before agreeing, and said to Zhang Haoyu: "Senior Brother Zhang, no problem, this matter is wrapped up in Senior Brother, don't worry, I will definitely investigate where Senior Sister Liu went last time, and then disappeared!"

Wang Sicheng thinks a lot in his heart, this is a good opportunity to win over Zhang Haoyu, as long as he can do this thing well, then Zhang Haoyu owes himself an adult invitation, then the possibility of winning over Zhang Haoyu will become much greater.

Zhang Haoyu looked at Wang Sicheng quietly, what Wang Sicheng was thinking in his heart, he could probably know, looking at the expression on his face, he was just thinking about how to win himself over, and it just so happened that Zhang Haoyu planned to give him such an opportunity, use himself as a bait, and then catch more big fish.

After discussing it clearly with Wang Sichang, Zhang Haoyu left the residence of the disciple of the law enforcement team with satisfaction, everything was ready, and the rest was to see how many fish Wang Sicheng, a big fish, could draw out.

......

After several days of discussion, the four demon saints finally reached a unified agreement, and temporarily held no action on the human race, but all the plans are still the same, and it is necessary to increase efforts to disintegrate the new forces of the human race from the inside, so that when the opportunity comes, it will become easier to attack the human race, relying on the tens of millions of troops of the demon race outside, and relying on the human race who have become the spies of the demon race inside, so that the human race can be completely defeated in one fell swoop.

This is the unification agreement reached by the last four demon saints, whether it is the main battle faction or the main peace faction, they are very unified with this plan, even if the main and faction of the demon clan want to occupy the Shenwu Continent in their hearts, the idea of occupying the Shenwu Continent has never disappeared, the reason why they became the main and the faction is that they don't want to start a war with the human race without being very sure, so the consumption of the demon race is too great, and the final result is not to think about it, it must be to sign a contract with the human race again, and finally the two races have been quiet for thousands of years.

It's because they don't want such a result to happen, so these lords and factions have never advocated doing anything to the human race, but now the main battle faction has made a move, and they have a very rigorous plan, so they also agreed, and for a while, the whole demon clan is united, and they are bound to become the real masters of the Shenwu Continent and turn the human race into their slaves.
