Super Invincible Battleship
Chapter 1426

Chapter 1426: Chapter 561: Complete Control Chapter 1426: Chapter 561: Complete Control Yan Fei was not a mindless person; he wouldn't dare to cultivate just any technique he came across. That's why he wanted to use the technology extrapolation system to deduct and perfect this technique. But unexpectedly, the always compliant technology extrapolation system went on strike, failing to conduct the deduction of this technique according to Yan Fei's request.

Unable to know whether this spiritual power training technique was harmful to the human body, Yan Fei hesitated. However, considering the perilous situation he and Dream Island were currently facing, coupled with the shadowy mastermind lurking in the darkness, Yan Fei felt he had no other choice. So, with determination, he began to circulate his spiritual power following the method described in the spiritual power cultivation technique.

To Yan Fei's surprise, the spiritual power training technique operated very smoothly and his body did not experience any accidents while it was active. In just a short hour, he completed the first circulation of the technique. Yan Fei then discovered that his spiritual power had increased tremendously, doubling from its previous level.

This outcome filled Yan Fei with joy, prompting him to immediately discard any lingering doubts and proceed with the second circulation of the technique. An hour later, the second circulation was completed. His spiritual power had once again greatly increased, albeit this time the increase was only by 50%. Even so, such growth was still exhilarating for Yan Fei, given that his spiritual power scarcely improved under normal circumstances. He continued with determination, starting the third circulation, and after completing it, the increase of his spiritual power was now only by 25%.

Yan Fei quickly discerned the pattern: as the number of circulations increased, the magnitude of spiritual power gain would decrease by 50% from the previous increase. By the time he reached the eighth circulation, the increase in spiritual power was merely 0.78%. Continuing this trend, even if Yan Fei circulated the technique once more, it would be difficult to achieve any significant increase in his spiritual power.

Nevertheless, in less than ten hours of practicing this spiritual power cultivation, Yan Fei's spiritual power had increased by 3.7 times from its original baseline. His spiritual power had recovered from the destruction of several drones and had become even stronger; thus, Yan Fei's spiritual power was already much greater than that of other God-level experts. Now, with a massive 3.7-fold boost, his spiritual power far exceeded that of other God-level experts.

What Yan Fei didn't know was that this technique he suspected might be harmful to humans was one of the most precious techniques in the World of Cultivation. If one wasn't highly gifted, it would be impossible to comprehend this technique. However, as long as one could grasp it and continue to practice, it was possible to greatly enhance one's spiritual power in a very short time. This technique was not disclosed casually; if Xuanhuangzi had not lost hope for the World of Cultivation and feared that his clansmen wouldn't meet the minimum requirements to refine the Control Boundary Stele, he would not have inscribed this technique on the Stone Stele.

However, this technique that exclusively cultivates spiritual power, although effective quickly, also had significant drawbacks. Initially, spiritual power increased rapidly, but as the number of circulations increased, the rate of increase would diminish exponentially. Eventually, the technique would no longer enhance spiritual power. Moreover, once one had cultivated this technique, cultivating other spiritual power techniques would yield no further growth. Thus, although effective quickly, this technique was in fact a one-time product that locked future enhancements of spiritual power, rendering oneself entirely immune to other spiritual power cultivation techniques.

Feeling spiritual power that was now 4.7 times stronger than before, Yan Fei's mind was clearer than ever, so he felt no regret. From now on, no matter what he did, his reactions would be much quicker. He could even extend his spiritual power outside of his body into space, using it to replace his eyes and truly observe the world. With such powerful spiritual power, Yan Fei now truly had the ability to refine the Control Boundary Stele.

Yan Fei returned to the center of the altar, took a step forward, sat down cross-legged before the Control Boundary Stele, adjusted his physical state, and then rested his hand against the vast Control Boundary Stele.

According to Xuanhuangzi's records, refining the Control Boundary Stele was an extremely dangerous process. Any disturbance by others, or any issues in the refining route, would not only nullify all previous efforts, but the refiner could also suffer death from spiritual power backlash. Due to such grave risks, Xuanhuangzi did not dare to forcibly refine this Cave Heaven Paradise during a critical moment.

Therefore, to protect himself, upon deciding to refine the Control Boundary Stele, Yan Fei's Drone Avatar automatically flew above his head. The Drone Quantum Radar would cycle on at a specific interval, ensuring no enemies could sneak in. To repel any possible intruders, the drone was fully prepared for battle, ready to launch a devastating attack the moment an enemy was detected nearby.

Sitting cross-legged on the ground, Yan Fei first reviewed the refining route recorded on the Stone Stele, then projected his spiritual power onto the Control Boundary Stele in front of him. The Boundary Stele was covered with many strange and bizarre Runes. Yan Fei did not recognize these Runes, but through Xuanhuangzi's explanation, he knew that they possessed amazing abilities beyond imagination, and the Cultivation Civilization had obtained formidable power through the application of these Runes.
