Cultivation is just so scientific!

Li Shiming chose a drone that is purely based on the technology from his previous life without any cultivation techniques. This medium-to-large transport drone consumes a significant amount of energy.

In the engine room space, he is able to use 5-nanometer control force to process some complex technological items. With sufficient materials, he manufactured an ultra-large capacity battery pack.

Without the need to consider costs, the battery pack he manufactured allows the transport drone to travel within a range of thousands of miles.

The reason for making this purely technological drone was precisely for the current situation.

Cultivators are extremely sensitive to cultivation techniques, especially when approaching their alert range; even a slight use of cultivation techniques might be detected.

However, purely technological means are different; cultivators do not pay attention to these. Even if they sense drones in the sky or tracked robots on the ground, they would only consider them as some sort of mundane matter.

Mundane matters are not worthy of a cultivator's attention; this is both a pride and a habit of cultivators.

The drone dropped off the tracked robot and returned, and Li Shiming waited for the drone to return to his side and retrieved it.

The abdomen of the tracked robot extended a drill, which started drilling into the ground. The drill contained an ultrasonic sensor.

Once the drill reached several meters deep, the ultrasonic sensor emitted ultrasounds, which continually spread underground. Some of the ultrasounds bounced back and were received by the sensor.

The signal was sent out by the tracked robot and transmitted through the drone's satellite system to Li Shiming's life-bound artifact, the IBMz15.

In Li Shiming's sight, the IBMz15 generated the internal structure of the mountain according to the transmitted data.

Of course, a single point of data cannot provide an accurate probe, so the tracked robot continuously drilled around the peak, and data was continuously received by the IBMz15.

As more data was collected, the internal structure of the mountain revealed itself.

Great Cultivator Zhao Qingfeng sat with mixed feelings in the mountain cave. This cave was one of his temporary abodes, known only to him.

He was severely injured this time, and the reason he did not seek help from the sect was because of the lack of friendliness within the Gu Feng Sect.

If he had truly gone to seek those fellow great cultivators' help, he feared they would seize him.

The fellow great cultivators had always coveted the 'Silver Winged Spirit Gu Insect'. He obtained the 'Silver Winged Spirit Gu Worm Egg' from an ancient ruin and, after countless explorations, had finally hatched twelve 'Silver Winged Spirit Gu Insects'.

This made him rank first among the great cultivators within the Gu Feng Sect. That fellow great cultivator had been looking for opportunities to obtain the 'Silver Winged Spirit Gu Insect'.

Thus, after being severely injured, he chose to stay in this secret abode to recover until he possessed some self-defense capabilities before considering returning to the Gu Feng Sect.

He consumed a healing spirit pill, but unfortunately, the late-stage Nascent Soul fourth-grade primary healing spirit pill's effect was less than satisfactory, only able to stabilize his injuries, not effectively treat them, which was akin to trying to extinguish a fire with a cup of water.

He couldn't help but shake his head with a bitter smile; this was the third fourth-grade healing spirit pill he had taken, and with each use, the effect worsened.

The injuries of a great cultivator are inherently difficult to heal.

His injuries were not just physical; within his Nascent Soul, scars resembling long snakes were left, containing the flames of Grandmaster Hu and the wind energy of Master Ding.

The two energies rampaged through his Nascent Soul and body, requiring him to use all his energy to suppress the scars.

This left him with virtually no external energy usage, reducing his combat power to nearly nothing.

Moreover, he couldn't fight anymore. If he failed to suppress his internal injuries, the energies left by the two great cultivators would explode, causing him fatal harm.

He closed his eyes and carefully circulated the spiritual power within his Nascent Soul, cultivating while avoiding the scarred areas.

Although this change in the cultivation route significantly reduced his cultivation efficiency, even the slightest increase in spiritual power was crucial to him now.

This was a long-term process. He needed to continue cultivating to gain spiritual energy, using it to counteract the consumption of fighting his injuries and employing secret techniques to heal them.

He estimated that his recovery would take at least four hundred years, exceeding the assessments by the fellow great cultivators because he wasn't returning to the Gu Feng Sect to receive resources from the sect.

As he was cautiously cultivating, a faint fluctuation swept over him. As he maintained extreme vigilance, he immediately sensed this fluctuation.

Soon, he relaxed upon realizing the fluctuation carried no spiritual energy aura, likely caused by some natural tremor in the area.

Following several more similar weak fluctuations, he stopped paying attention, as no spiritual energy aura indicated mundane matter, which is not a concern.

Great Cultivator Zhao did not know these were ultrasounds emitted by the tracked robot.

Li Shiming observed the internal structure map of the mountain drawn by the IBMz15 and saw the outline of an abode.

Since the abode was deep within the mountain belly, and the formation used by Great Cultivator Zhao was mainly for concealing purposes with almost no additional functions, it couldn't stop the penetration of ultrasounds.

Great Cultivator Zhao only used a Concealing Array because if a cultivator did track him here, a Defensive Array would be of no use at all.
