The medicine powder was scattered into the air by Qin Ning. After it floated to the ground, the white medicine powder suddenly turned dark green.￥f

These dark green traces began to be messy. As Qin Ning peeled off bit by bit, many dark green traces pointed to a place.

An ancient well in the middle of Yanwu City!

Near this ancient well, dark green traces almost covered all the ground. The traces here are messy, but there are also some clear marks.

Through the mark analysis, Qin Ning can once again determine that this is the trace of the Siren clan.

Ancient well?

This made Qin Ning think a little hard. How could the Siren Clan gather here?

Suddenly, Qin Ning's mind lit up. By the way, some ancient wells can lead to underground water sources, while underground water sources may be together with underground rivers.

Yes! That's right, it's the underground river!

No wonder the Qin army intelligence personnel on the ground sprinkled a net of heaven and earth, but did not find the whereabouts of the Siren tribe. Even if they reconnaissed all the rivers, they found nothing. It turned out that such passages were ignored.

Nothing happens, as long as you figure it out, there will be no mystery. If the Siren tribe knows that an underground river can lead to the territory of the Qin army, then they will definitely not be able to detect this path by the Qin army. This will achieve the suddenness of the strategy and make the Qin army unable to defend!

Qin Ning knew that there were many underground rivers that could flow into the sea. People on the land might not know about these underground rivers that flow to the sea, but the sirens clan, who had been underwater for many years, must have known about them.

It is also entirely possible that they can use the underground river they know to act to avoid the surveillance of the Qin army.

Thinking of this, Qin Ning did not hesitate anymore and immediately jumped down the ancient well. He didn't know how deep the water in the ancient well was, so Qin Ning swam downwards. He didn't know how long it took to separate the water surface. With a thud, Qin Ning exposed his head from under the water.

A surging underground river!

Qin Ning could feel the flowing speed of this underground river was very fast. Looking up, the width of this underground river was amazing, more than ten meters wide. Above the river was an arched underground cave, winding in front and behind, and there was no way to see where it led.

Such conditions may be a place that is not suitable for humans to move quickly. But for the Siren clan, it is definitely a good place to march.

Qin Ning flew out of the water and flew above the water. Since Qin Ning didn't know how many turns he turned when the ancient well led here, he had lost all his sense of direction when he got here. All he had to do was to judge the direction of the martyr tribe's progress.

After thinking for a long time, Qin Ning put his ear on the wall of the Dark River Cave. It is deep underground and there is no other noise interference. As long as you listen quietly, you can hear the sound coming from a long distance.

Sure enough, under Qin Ning's listening, a faint but extremely noisy sound came from afar.

Following the direction of the sound, Qin Ning flew over carefully.

In less than a quarter of an hour, Qin Ning caught up with the noisy sound. Qin Ning didn't dare to get too close. So he slowed down and wanted to get closer a little bit.

Suddenly, several golden lights came from different directions in the air. Qin Ning wanted to take it forward, but suddenly felt that the golden light could not be touched. With a flash of thought, Qin Ning plunged into the dark river and hid under the river.

After a while, two soldiers from the Siren clan swam over.

Qin Ning used the change of power and changed into the appearance of a siren clan, swam over to the two siren soldiers.

"What are you doing?" The two sirens soldiers thrust the spears left and right, crossed them to one place, and asked Qin Ning.

Qin Ning quickly pretended to be scared and said, "Two brothers, I am left behind. The undercurrent in the river just now was too strong. I was swept away all of a sudden and I finally caught up."

The two Siren soldiers looked at me, I looked at you, and Qin Ning again. One turned his head and said to the other: "It should be ours, right? The flow rate on the river surface was not small just now, and there was probably undercurrent, maybe it was washed away."

Another said, "No, how could the projection golden light be activated? The person above said that the projection golden light will only be activated when people from non-Simon clan appear. What happened just now?"

After hearing this, Qin Ning immediately realized that what the two Siren soldiers said should be a detection alchemy product. As long as it is not a set object image, it will be triggered.

Thinking of this, Qin Ning said, "Two brothers, I just saw something flying in the air, which scared me so much that I hid, and only then did I dare to come out when I saw you."

The Siren soldier who had just spoken suddenly realized: "So that's how it is. No wonder it triggered the shadow golden light. Something flew in. But the shadow golden light did not capture the flying image. Do you see clearly what it is?"

Qin Ning cried and said, "I'm almost scared to death. I'm just escaping my life. How can I care about looking at other things? I just knew it was a shadow, and I didn't know anything else."

"Well, the situation you know is very important. In order to prevent someone from following, the superiors specially created this projection golden light. You can follow us and just tell us what you know at that time."

As he said that, the two Siren warriors led Qin Ning forward.

After a while, under the leadership of two sirens soldiers, Qin Ning caught up with the last sirens army. The troops behind the hall were only 10,000, but they also seemed very crowded in the underground river.

Two Siren soldiers led Qin Ning to see the general who was instructed to the latter part. When they told the general about what they learned, the general immediately showed a suspicious look on his face.

"Come here." General Siren pointed at Qin Ning and said.

Qin Ning pretended to be trembling and came to the Siren General: "What order do you want me to give?"

"You just said that you saw something flying, but you didn't see clearly what it was, right?"

"Yes, I was scared and didn't see clearly."

"Well, this is understandable. Which part of you are from? How could you be washed away by the undercurrent?" The sirens general said, staring at Qin Ning with both eyes.

Qin Ning suddenly smiled and said, "You should know this."

"I know?" The Siren General was stunned and said subconsciously: "What do I know?"

After saying this, General Siren felt something was wrong, because in his eyes, the Siren in front of him was as deep as the night sky, and he seemed to fall into it and could not extricate himself.

The Siren General struggled desperately, but found that his body was no longer obeying the command, and his entire consciousness was trapped in the other party's deep sea of ​​consciousness.

Qin Ning's God Control Art once again played a miraculous effect. He quickly looked through the memory of the siege general. This time, Qin Ning really made his body full of energy.

Although the Siren tribe only came with an army of 200,000, these soldiers are not ordinary garbage warriors who turn into meat paste after meeting each other. Those are all competing for quantity, and they are cannon fodder among cannon fodder.

The army gathered this time is all selected from the Siren clan elite, an absolute elite force! And ten super-strong Siren generals were dispatched. If we look at the quality alone, the Siren clan can be regarded as the elite.

They only have one purpose, that is, to destroy all the cities of the Qin army and to clear all life in the places they pass through!

Moreover, Qin Ning also saw a map of the underground river in the general's mind. In the Abyss Empire, underground rivers are well connected, and almost all the cities have places where underground rivers can appear.

Just when Qin Ning was still trying to read the memories of the Siren General, he heard a Siren Warrior beside him ask: "General, what's wrong with you?"

Qin Ning was shocked. There were so many sirens warriors next to him. He was not afraid of these warriors, but it would be a big deal if he was alerting the snake.

Thinking of this, Qin Ning didn't bother to look at the Siren General's memory, so he quickly controlled the Siren General and said, "It's okay, I just want to see if this Siren Warrior is a spy. I have checked it, and there is no problem. It knows a lot of things, so it is by my side."

The Siren Warrior next to him did not doubt it when he heard this, and then asked, "General, what should we do? Should we keep up with the front?"

Qin Ning controlled the Siren General and said angrily: "If you don't go forward, you still have to stay here? Of course, you are walking forward."

The soldier hesitated and said, "But we haven't followed the peak yet to explain what happened here."

"Do I need to teach such a little thing? Of course, it means that everything is normal. Go and go, don't bother me with these nonsense."

When this unit still needs the army to continue moving forward, Qin Ning then looked through the memory of the Siren General and found that their 200,000 troops had a clear division of labor, including a front-end reconnaissance unit, and a small force that deployed poisons. Next was the attacking unit, and finally the rear of the palace troops here.

The small army that was using poison attracted Qin Ning's interest. They were not poisoned. These siren warriors themselves were able to secrete a toxin that could cause psychedelics. Extracting these toxins into the drinking water of humans on the ground can cause people on the ground to get poisoned and mentally disordered, and in severe cases, they will become coma.

This explains why Yanwu City has a strange situation where the whole city dies collectively without sending any news. It seems that the troops of the Siren Clan are really difficult to deal with.

When the Qin army encounters such an opponent, it has no combat experience, and there is no suitable venue for fighting with them. People only play hide-and-seek like you. What can you do? When the Qin army has to face other enemies, the army of the Siren clan is very threatening.

At this moment, a powerful voice sounded: "Where is your general? Let him come to see me!" (To be continued, please search for Astronomy, novels are better, updated and faster!
