Infiltration

The reconnaissance capabilities of flapping-wing drones in open spaces are indeed excellent, but places like caves, especially when it comes to eavesdropping on cultivators, present some challenges for them.

After all, cave space is limited, so it's not unusual for a bird to fly in.

However, the people of the Gazing Immortal Sect are clearly plotting something. If the sound of birds flapping their wings coming from the cave is reasonable, they will cautiously investigate.

Yi Xuan's flapping-wing drones look very similar to birds, but a cultivator's Divine Sense can detect their true nature in an instant.

Therefore, how to enter the cave without disturbing the people inside became a major problem.

For cultivators, such unsolvable problems that arise suddenly might be quite difficult, but for Yi Xuan, given enough time, there is no problem in this world that cannot be solved.

Yi Xuan had the Butler recall the two drones, and then he was seen gesturing back and forth with his hands in front of the projector.

In no time, a brand new flapping-wing robot appeared on the holographic projection, or rather, a deformed flapping-wing robot, because Yi Xuan had actually added a quadruped system to the lower part of the robot, thus giving the flapping-wing robot the ability to walk on land.

Yi Xuan glanced over and noticed that the Temperature-Controlled Separation Furnace had stopped working, so Yi Xuan quickly took the Golden Flame out of the furnace and put it into the 3D printer not far away.

Under the Butler's control, the 3D printer began printing the parts used in the quadruped system.

In less than an hour, the two flapping-wing drones returned to Yi Xuan's stone cave, looking at the parts that were already completed and those that were still being printed.

Yi Xuan decided not to wait any longer. After all, things could change at any time with the Gazing Immortal Sect, and if he was late, who knew what might happen? Yi Xuan always felt that the Gazing Immortal Sect had bigger plans this time.

Thinking about it now, it's a bit strange. The Gazing Immortal Sect was clearly the loser in the previous battle between the two sects, yet before entering the Artifact Ruins, the elders of the Gazing Immortal Sect were so arrogant towards the disciples of the Azure Cloud Sect. Didn't they worry about Yi Xuan and the others reporting this when they returned to their sect?

At that time, the three elders of the Azure Cloud Sect might once again overpower the Gazing Immortal Sect and demand an explanation.

Yi Xuan thought that either Elder Liu was like a dog, wanting to bite everyone he met, or the people from the Gazing Immortal Sect were acting with impunity. Thinking this way, Yi Xuan became worried: could the Gazing Immortal Sect's backup plan be aimed at the Azure Cloud Sect?

With that in mind, Yi Xuan quickened his pace, and as the parts were installed one by one, the remaining parts in the 3D printer were completed.

In this way, Yi Xuan quickly completed the modification of the two drones. Looking at the flapping-wing drones on the control panel, which could now move smoothly using the quadruped system, Yi Xuan nodded in satisfaction.

Then he took the two airplanes out of the cave and threw them into the sky.

As they soared into the sky, the flapping-wing drones began to flap their wings. Then, like two deformed little birds, they circled Yi Xuan a few times before flying towards the direction where the Gazing Immortal Sect disciples had been spotted earlier.

Back in the cave, Yi Xuan let out a long sigh of relief. He then stared at the monitor on the screen showing the Gazing Immortal Sect and asked, "Butler, how is it? Any movement over there?"

"Boss! There's nothing unusual, but they've switched people. Two people came out of the cave and replaced the previous two inside."

Yi Xuan nodded, while anxiously hoping that the two flapping-wing modified aircraft would pass by quickly.

Unfortunately, although Yi Xuan's ornithopter had excellent performance, Yi Xuan mindless modifications still had a significant impact on its performance.

It took two drones a full hour and a half to get close to the cave.

Seeing the footage transmitted back by the two drones, Yi Xuan finally breathed a sigh of relief.

So they quickly arranged for two drones to infiltrate the cave.

Two ornithopters flapped their wings and swept over the heads of the two disciples at the cave entrance. Since there were many birds in this secret realm, they did not attract the attention of the two.

Two drones landed directly above the two people in a blind spot. Then, a faint mechanical sound came from the drones, and the wings of the two ornithopters detached from their fuselages. Without their wings, the ornithopters instantly became quadruped robots, looking like giant cockroaches.

The Yi Xuan has installed suction cup-type soles on all four legs, allowing it to better adapt to various environments.

Two quadruped robots entered the cave one after the other by climbing up the rock wall, while the two disciples at the cave entrance were completely unaware of the intruders' arrival.

After the robot entered the cave, it discovered that this cave was completely different from the one where Yi Xuan was; that cave looked deep and long.

In contrast, Yi Xuan's cave was something Yi Xuan was too embarrassed to call a cave; it was just a cave dwelling.

The two quadruped robots walked deep into the cave for a long time before discovering something different. At the end of the cave was an open space of several tens of square meters.

In the middle of the open space, six disciples of the Gazing Immortal Sect formed a circle, surrounding a completely naked person. All seven of them were sitting cross-legged. Only one person stood not far from the other seven, watching them with a solemn expression.

"What's going on here?" Yi Xuan muttered to himself, looking at the Gazing Immortal Sect disciples. From the scene, Yi Xuan could only guess that the Gazing Immortal Sect disciple in the middle, who was shirtless, was seriously injured, and the others were healing him.

However, this completely contradicted what the two guards at the entrance had said earlier. If Yi Xuan were in the cave at this moment, he would definitely have pointed at them and told them to stop talking in riddles.

"Ugh!" Suddenly, the naked man in the middle groaned and opened his eyes, a flash of blood red appearing in them.

The disciple standing not far away, upon seeing this scene, actually revealed an expression of excitement in his eyes.

"Junior Brother Qi! How did it go? Did it work?"

Hearing the man's question, the man surnamed Qi nodded, his expression pained, and said, "Senior Brother Qian, it's almost over. I didn't expect it to be even more painful than I imagined! I'm only able to hold on this long thanks to Master's Blood Cloud Pill!"

The disciple surnamed Qian nodded and said, "Indeed, our sect leader is truly a man of great hidden talent. I never imagined he would have laid this out fifty years ago. Now, as long as you, junior brother, can fully integrate it, this Artifact Ruins will be like a backyard for our Gazing Immortal Sect. But as for the other sects in the Southern Frontier? Hehehehe..."

From the man's wicked laughter, Yi Xuan knew that nothing good would come of it.
