Li Yu first installed six surveillance cameras on the hotel's exterior wall, covering almost all directions and angles, and also included a nearby street and two alleys.

In addition, he also purchased some wireless monitoring equipment last time he went back, and this time he also brought it with him, the principle of these wireless listening devices is very simple, similar to a radio station, which can use a specific frequency band to send and receive information, and can be used without networking.

The disadvantage is that the pickup radius is only about one meter, and it is difficult to hear it when it is far away, but Li Yu only uses them to listen to the movement in several nearby buildings, and the bully is that the target is ignorant of modern eavesdropping technology.

He even had people give these items as gifts to the subject of suspicion, claiming that there was some kind of luck in them.

Many people have found a treasure and strung it with rope and put it around their necks, refusing to even take it off when they sleep.

As for the round camera that looks like a big eyeball, everyone will be amazed when they see it, but no one will shy away from it, and some people defecate everywhere in front of the camera.

I didn't wipe my butt after pulling it, I put on my pants and left.

Except for Li Yu, probably no one realized that the first spy war on the Blatis continent had just begun.

And the other side of the war has no idea what kind of war it is drawn into, from beginning to end.

Because the victory came too easily, Li Yu didn't even feel any sense of achievement.

With the double blessing of video recording and radio equipment, it only took three days for David's hidden outpost near the hotel to be found.

And during this time, the man sent by Huls also came twice, and the man was very cautious, and each time he appeared in the middle of the night, wrapped himself tightly in his cloak, showing only a pair of eyes, and went away immediately after shooting the arrow, never stopping.

He sent the female lord the time and place of the meeting, but the girl ignored it for the time being according to Li Yu's arrangement before leaving.

By the third time, Hulse was obviously a little anxious, because David had been hunting down his remnants in the city these days, searching for his traces.

Huls felt the pressure and was even more desperate to see Ilea.

So it wasn't long before he sent another messenger, and the man had just bent his bow in the darkness and aimed at a window on the second floor, and before he could let go of the bowstring, a crossbow came out of the window, and the next moment a small red dot appeared on his chest.

Without hesitation, the crossbowman on the opposite side pressed the mechanism, and the bolt fired, hitting the messenger in the chest.

For a moment, the messenger thought he was dead, after all, he had only come to deliver the message, and he was not wearing any armor.

But then he found that the bolt had hit his body and had bounced off and fell to the ground.

The crossbowman on the opposite side didn't want to kill him from the beginning, the head of the crossbow bolt had been smoothed out, and it was not lethal.

And the messenger also noticed the note wrapped around the arrow.

He didn't have time to think about it, grabbed the bolt that had fallen from the ground, and then hurriedly disappeared into the night.

Unbeknownst to him, however, in the night sky behind him, a drone also quietly rose and followed him like a ghost.

With the remote control in hand, Thomas jumped from a window on the side of the second floor, and then climbed up the opposite stone wall without stopping, and quickly jumped over the wall......

This is a safe route that Li Yu has planned to avoid all the secret posts in the vicinity. The Prophet of the Shuangxiu Sect had originally planned to catch up on his own and experience what it was like to sneak through Assassin's Creed.

But considering his skills and foot strength, he wisely chose to give up in the end.

The drone has a remote control distance, if you can't catch up with the speed of the opposite side, you lose the person, then the fun is great, and you may also hit the guards of the Figuerola family on the way, so you have to dodge in time.

Therefore, during the safe period, Li Yu still chose to lend the sacred bird of the Shuangxiu Sect to Thomas to control it.

The new knight was trained by Alfred, he was very skilled, agile, and his actions were always calm and calm, so Li Yu could rest assured that he had entrusted this important matter to him.

Since he didn't need to rely on his eyes to track his target, Thomas could hang far behind the courier, minimizing the risk of being discovered.

Rao is the messenger sent by Huls is alert enough to look back from time to time, and deliberately detours several times, but he can't shake off the drone hovering overhead.

Eventually, the messenger flashed and slipped into a perfume shop.

Thomas didn't follow, but first piloted the drone to the top of the perfume shop, and after waiting for a while, he saw the messenger who had sneaked in quietly leave through the back door and escaped into the night again.

Thomas was about to follow again, but suddenly he thought of something and stopped again.

Then he zoomed in on the image on the drone according to Li Yu's instructions, and noticed that the crossbow arrow in the messenger's hand was gone.

Thomas's eyes narrowed, he wasn't sure if he had taken the letter from the crossbow or left it in the perfume shop.

Seeing that the courier was about to run out of the drone's surveillance range, the knight knew that he had to take a gamble, and he finally chose to stay.

After waiting for about three minutes, the back door of the perfume shop was pushed open again, and this time it was a diminutive guy who ran out.

He was holding a slender package in his hand, judging by the size and shape of the package, it should be the crossbow arrow inside.

Thomas breathed a sigh of relief, and when the man had also run some distance, he followed again.

Before the drone's battery was depleted, Thomas saw the man run outside a palatial-looking mansion, threw the package in his hand hard, and then lowered his head and left in a hurry.

Thomas narrowed his eyes and took a closer look at the building in front of him.

After a while, he finally remembered which property this was, and he couldn't help but be surprised, and then he didn't stop long, and soon returned to the inn to report to Li Yu and Ilea what he had seen tonight.

Miss Rabbit was also taken aback when she heard Thomas talk about where the crossbow bolt ended up, "Are you sure you read that right, it's the property of the Campos family?" ”

"You can't go wrong." Thomas said, "I happened to pass by there when I was in Rock Snow City last time, and I specifically asked the people around me about it, and that place belongs to the treasurer Goldfinger Romero. ”
