The five of them rested in the waterway for half an hour, and the physical energy consumed by diving gradually recovered. Zhu Xiaoyan confirmed that the time was about the same, took a deep breath and said, "Let's go!"

He took the lead in walking deep into the waterway, and Han Mo and the other two followed behind as they listened to the sound of moving water.

After a while, the originally dark vision gradually became brighter. Although it was still extremely dim, it could roughly see the outline of the companion's body.

The few people had already held the dagger in their hands, calmed their energy, and moved forward with great caution. Soon they saw an iron gate appearing in front of them, and the light came out from the gaps of the iron gate.

This waterway is winding. When you walk to the iron gate, the lake water will only reach the waist. The iron gate will immediately intercept the waterway.

The five people approached the iron gate against the wall. Han Mo saw that the iron gate was tied with thick iron chains as thick as his arms, and even had two fists that were too big to lock, so he frowned.

Although he was extremely strong, he could not open such a thick metal refined chain.

The other three dark officials also frowned. After finally coming here, they were blocked by an iron gate. Wouldn't the previous efforts be wasted?

Fortunately, there is Zhu Xiaoyan.

Of course, he knew that there was an iron gate here and was sure that there was no one else in the waterway. Then he went forward and looked carefully. A sneer appeared on the corner of his mouth, and he actually took out a key from his body.

Han Mo was surprised when he saw it. If Zhu Xiaoyan was already very surprised by the terrain of the Black Tower, then he actually had the key to open the iron door, which was shocking.

The dark officials looked at Han Mo at this time.

Han Mo knew what they meant, and Zhu Xiaoyan was too familiar with all this, so familiarity made people suspicious of him.

If it weren't for the close relationship with the Black Flag, how could Zhu Xiaoyan be so familiar with this place, and he also had the key to open the iron door?

This time, he was a risky person, and the dark officials' style of conduct has always been extremely cautious. At this time, Zhu Xiaoyan's various actions made them suspicious, and naturally they became worried about Han Mo's safety.

If Zhu Xiaoyan is really a Black Flag person, will he take everyone into a trap?

Zhu Xiaoyan opened the door, gently removed the iron chain carefully, pushed open a gap, and did not answer, but seemed to know the Dark Officer's suspicion of him, and his voice was very calm: "You can choose whether to go in or not. If you think I am not trustworthy, it's better not to go in!"

Han Mo did not say anything, and came over directly and walked into the iron gate without hesitation. When the three dark officials saw that Han Mo had all entered, they didn't say much, and followed them very resolutely.

Zhu Xiaoyan then followed everyone into the iron gate.

The waterway was very narrow, but there were two wall fires lit. The dim light was spread by these two wall fires. Zhu Xiaoyan had already walked beside Han Mo and lowered his voice: "This is all black water oil, add lamp oil once every half a month!"

Han Mo asked softly: "Where will Du Wufeng be?"

"There are five floors in this black tower. Du Wufeng always likes to stay on the fourth floor." Zhu Xiaoyan whispered: "The fifth floor of the black tower is the archives of the Black Flag. If Du Wufeng is in the Black Tower, he will definitely be on the fourth floor."

Dark official Chi Shi said, "Sir, if the target is on the fourth floor, then there will inevitably be ambushing the first to third floors. As long as you pass through these three floors, once you take action, you will surely alarm Du Wufeng!"

Zhu Xiaoyan nodded slightly and said, "What you said is indeed right. There is indeed an ambush in this tower. The first floor is just down, but on the third floor of the pagoda, whether Du Wufeng is here or not, there will be two or three first-class black flag elite guards."

The poisonous bat frowned and said, "There are traps everywhere on this mountain, and there must be many black flags in ambushing. Once the people in the tower are disturbed and the black flag in the tower sends out a signal, then all the black flags in the mountains will come to support us, and we may not be able to get the antidote!"

Zhu Xiaoyan smiled faintly and said, "This mountain is not as good as you imagined." He whispered: "In fact, the strength of the Black Flag is no longer as good as in the early years. Before your Xihua Hall and the Purple Uniform Guard of Qing Kingdom were founded, the Black Flag was indeed the world's number one dark yamen. At that time, there were many people and powerful people. However, later they fought with Yanqing and lost a large number of elite troops. It was not easy to cultivate a qualified Black Flag again. Although the Black Flag trained a group of new officials every year, it could not keep up with the number of people that had been lost."

Speaking of this, the eyes of the three Red Rats were shining.

These three people are veteran officials in the West Flower Hall. They are extremely excellent in the West Flower Hall in terms of ability and experience. It is precisely because of this that Han Mo brought them by his side.

These three people have been in the West Flower Hall for many years, and they secretly have had many battles with the Black Flag. There are really many black flags of the Wei Kingdom that died under their hands.

"Although this is the General Office of the Black Flag, not all Black Flag officials know this." Zhu Xiaoyan said slowly: "This is where the Black Flag order is issued. Many orders are sent from here to the branch of the Black Flag, and the branch will then issue the task orders to the Black Flag School of the Bazi Team, and the Black Flag School of the Bazi Team will dispatch personnel to carry out the tasks."

When Han Mo heard him say this, he immediately remembered the officer of the Xihua Hall who had once lurked in the black flag. The Qingying among the "Four Silver Eagles" became the Black Flag School of the Qianzi Team among the black flags. It was precisely because of the existence of the Qingying that the dark side of the Ximen family colluded with the black flag of the Wei Kingdom.

"What do you mean is that there are not many black flag officials on this mountain?" Han Mo naturally heard what Zhu Xiao said.

Zhu Xiaoyan whispered: "The black flags are distributed everywhere, performing tasks. There are not many black flags guarding this place, but on the whole mountain, they are all guarding the key points, echoing each other, and controlling the mechanism traps on the whole mountain. There is such a group of people and the mechanism traps on the mountain, which is better than thousands of troops...!" He looked ahead of the waterway and said slowly: "If I hadn't known about this passage in advance, I wouldn't have let you come and take risks."

Han Mo asked seriously, "Although there are not many black flags on the mountain, this place is their General Office. Once they are really alarmed, the power of the five of us may not be their opponents!"

As the director of the West Flower Hall, he naturally knew very well about the Dark Officer.

The dark officials may not be very skilled in martial arts, but they are good at sneak attacks and never talk about morality to the enemy. The ultimate goal is to use any means to kill the enemy. Whether it is a hidden weapon or a poison, it is never taboo to use it.

Faced with such a group of black ghosts, and they are above their territory, even if they are not large in number, Han Mo and others will be threatened by powerful threats.

Zhu Xiaoyan nodded and said, "Yes. It's really difficult to be entangled by them. So we must fight quickly and kill Du Wufeng as quickly as possible, and then get the antidote. After the antidote is obtained, we quickly withdraw from the bottom of the lake!"

The three dark officials all frowned slightly.

Du Wufeng is the leader of the Black Flag and one of the famous generals in the world. It is extremely difficult to kill him, but it is almost impossible to kill him quickly.

"Do you have any plans?" Han Mo couldn't help asking when he saw that Zhu Xiaoyan was quite confident.

Zhu Xiaoyan pondered for a moment and finally said, "There is a way, maybe it can be tried. Although it may not be successful, this is probably the only way at present."

"you say!"

Zhu Xiaoyan looked at the red mouse and said, "Transfer the tiger away from the mountain and let it go!"

"Transfer the tiger away from the mountain?" Han Mo frowned and said, "Let me go?"

"Turn away the guards, you and I will join forces to injure Du Wufeng with one blow." Zhu Xiaoyan looked cold: "Only in this way, there is a chance to have a front-line opportunity!"

Han Mo narrowed his eyes.

When Chi Mouse heard Zhu Xiaoyan's words, he understood the meaning and whispered: "Sir, the three of them are willing to take action to lead the guard away and create opportunities for you!"

Han Mo pondered slightly and said to Zhu Xiaoyan: "You should talk carefully!"

"I have observed this black tower for a long time, and I am very clear about the strongholds on this mountain." Zhu Xiaoyan said slowly: "The outside of this black tower is almost within the Black Flag's gaze... but almost, after careful calculations, I found that one of them was not within the Black Flag's gaze."

Han Mo had noticed before that this black tower was a black tower on all sides. After hearing Zhu Xiaoyan said this, he seemed to understand something. His eyes were shining and he whispered: "What are you talking about..."

"Zhengdong!" Zhu Xiaoyan said: "Du Wufeng has a habit. When he is in the Black Tower, he will stand at the window to watch the sunrise every morning, but he is afraid that someone can see him. Therefore, although the entire mountain is covered with many eyeliners, he can see all sides of the Black Tower, but no one can see the east side."

"I understand what you mean." Han Mo said slowly: "You mean, let people come in from the tower, attract those guards and drag them down, and we climb up from the east outside the tower, and then suddenly attack Du Wufeng?"

Zhu Xiaoyan nodded and said, "Yes. You and I climb up from the east, no one can see it. There is a window open on the east side of the fourth floor of the tower. At that time, I will sneak in first, and then you can take the opportunity to take action." He sneered: "Du Wufeng's martial arts is the strongest martial arts. If he gets the bow and arrow, you and me are definitely not his opponents, but as long as we stop him from getting the bow and arrow, his power will be greatly reduced, and you and I will have a chance to fight him!"

Han Mo was silent for a moment and finally said, "Okay, that's it." He looked at the three of Red Mouse and said, "Chi Mouse, you three will hold the black flag in the tower at that time, and Xiao Zhu and I will attack Du Wufeng."
