Qi Yuancheng went deep into the mysterious cave and found a strange crystal.

Qi Yuancheng motioned for the two of them and the tiger to step back a few points, so as not to be affected by the accident. Liu Dachao and Quan Chenghao saw the scene where the tiger was shocked out just now, and honestly retreated a few meters away, only the tiger squatted beside Qi Yuancheng indifferently.

Qi Yuancheng adjusted his breathing evenly, and began to let the Gu mist, which was already as thick as liquid, slowly surging towards the black crystal held in the palm of his hand.

As soon as the green mist touched the crystal, it did not cause a violent rebound as Qi Yuancheng imagined, but was frantically absorbed into it, and in a blink of an eye, the original dark green cloud of Gu mist became much lighter, and there was no sign of stopping.

Qi Yuancheng was a little shocked when he saw this. He wasn't sure if this situation was a blessing or a curse, and whether he should quickly withdraw his hand and retract the green Gu Mist. In an instant, his intuition told him that he couldn't just stop like this, but fortunately, he was already prepared, and hurriedly urged the source field force, releasing more Gu mist and surging towards the black crystal.

The two people in the distance also sweated for Qi Yuancheng, and only the tiger squatted on the side and looked calm

Qi Yuancheng felt the feeling of the black crystal feeding back through the constantly outputting Gu mist. "This feeling does not seem to be dangerous, but there is a kind of—" he was a little surprised, "-- a feeling of reassurance? ”

Qi Yuancheng found that after his Gu mist flowed into the black crystal, he didn't have the kind of vitality that he had after the loss of Gu Mist before, but instead felt that the source field power of these Gu Mists was like a hundred rivers returning to the sea, returning to where they should have been.

With the passage of time, the source field power in Qi Yuancheng's body had been consumed by seventy or eighty percent, which made him a little secretly anxious. Once the source field power is fully absorbed, and he doesn't have a letter stone by his side to replenish it, the battle in the future will be very passive. His mind moved, intending to stop the output of the Gu Mist, but he found that the flow of the Gu Mist was completely out of his control at this moment. The source field power and Gu mist seemed to have a will on their own, and they flowed happily towards the black crystal.

"Not good!" Qi Yuancheng shouted. Liu Dachao and the two were a little far away, and before they could react, the tiger had already swung its claws towards the black crystal.

Unexpectedly, the tiger's attack this time was not rebounded by the crystal, but it was also not helpless by the crystal. Quan Chenghao on the side lost his voice and said: "I, my source field power has failed!" ”

It turned out that Quan Chenghao heard Qi Yuancheng's warning, and was about to mobilize the source field force to move over quickly to help, but found that it could not be used at all. Liu Dachao also tried to fly up when he heard this, and he also jumped up on the ground and fell back.

"This crystal is really evil!" Qi Yuan became enlightened, "It can not only absorb the source field force, but also rebound the source field force, and now make our source field force invalid, it is simply the nemesis of the source field force!" ”

Quan Chenghao approached with a heart, "Such an evil thing, let's destroy it quickly!" ”

Qi Yuancheng smiled bitterly: "Just a few of us, there is no way to take it." What's more, my source field power is almost sucked dry by it! With that, his legs went limp, and he sat down on the ground, and his source field power and physical strength were exhausted.

"Oops! I'm also losing my source field power! Liu Dachao exclaimed.

"Me too!" Kwon Sung-ho's voice trembled.

"Roar!" The tiger's body was low, and it was obvious that it was also in the path of the black crystal.

"Everyone, don't panic!" Qi Yuancheng propped up the ground with his arm and said to everyone, "My Gu Mist maintains a connection with the crystal, I can feel that the crystal is not threatening, we should be in no danger." ”

With the addition of the two people and one tiger source field force flow, Qi Yuancheng's pressure plummeted. He was able to draw his mind and try to grab the energy of the crystal with the help of the Gu Mist.

This was not Qi Yuancheng's unintentional move, but a decision made after observation. He found that this inconspicuous-looking crystal stone with strange powers gave him a feeling that was somewhat similar to the letter stone, but it was different. The characteristic of the letter stone is that it allows the source field force to absorb energy, and at the same time, it can easily establish some kind of connection with the source field force.

In addition to transmitting a large amount of information when the Source Field Force is initially activated, this connection also allows the Source Field Force and the Xinshi to "locate" each other in each subsequent contact. It is also through "positioning" that the source field force can know the amount and characteristics of the energy possessed by the letter stone without hindrance.

It was in the process of Gu Mist injection that Qi Yuancheng noticed this familiar "positioning", and he concluded that the black crystal was most likely a mutant letter stone.

As soon as his mind moved, Qi Yuancheng's Gu mist became a channel for him to absorb crystal energy. At the beginning, the Gu mist was counterattacked by the crystal, and the part of the Gu mist that condensed Qi Yuancheng's thoughts instantly turned into nothing, transforming back into the energy of the source field force.

Qi Yuancheng hurriedly tried to absorb this part of the energy, although it was extremely difficult, but he slowly succeeded. He was pleasantly surprised, and continued to use this method to try to "recapture" the energy that had been sucked away by the crystal.

In this way, Qi Yuancheng was absorbed by the crystal on the one hand, and used the Gu mist to replace the energy back. He found that although the amount of energy converted back by the crystal was small, it contained an extremely high energy value. Gradually, Qi Yuancheng's "out" and "in" gradually reached a balance, and his body, spirit and crystal also established a subtle connection.

From that moment on, Qi Yuancheng felt that he and the black crystal seemed to be one, and he could even feel the energy flow of Liu Dachao and the others through the crystal. He tried to intervene in the flow of the three energies, but failed, and instead disturbed the balance between himself and the crystal, and the energy absorbed by the crystal once again exceeded the absorbed part.

Qi Yuancheng hurriedly gathered his mind and tried to maintain the delicate balance he had before. He adjusted his breathing, intending to increase his grasp of crystal energy.

Qi Yuancheng began to try to increase the transformation of a trace of Gu mist in exchange for the transformation of more energy. Sure enough, the balance was broken, and the energy absorbed by Qi Yuancheng began to be greater than the energy he output. This feeling made his mood extremely happy, and the previous pain and fatigue gradually disappeared.

At this moment, Kwon Sung-ho shouted in a weak voice: "I'm dying!" Liu Dachao also snorted and sat down on the ground. Even the tiger was so staggered that he almost fell.

Qi Yuancheng had a bad heart, and he patronized to experience the wonderful feeling of being in balance with the crystal, forgetting that the three partners were still struggling.

Qi Yuancheng once again tried to interrupt the energy absorption channel of the other two people and one tiger in the crystal's energy system. To his surprise, his attempt did not trigger a rebound of the crystal, but actually slowed down the energy absorption.

"Could it be that my absorption of crystal energy is greater than the input to it, and I take the initiative?" Qi Yuancheng said secretly. But this was not the time to think carefully about the reason, he gradually increased the interference with the three energy channels, and actually stopped the energy absorption of the two people and one tiger.

"Whew!" Kwon Sung-ho lay down on the ground with relief, "Is this guy full?" ”

Liu Dachao wiped the sweat from his head, "I think it seems that the crystal has just interfered with our energy absorption, so this pull was interrupted" He turned to Qi Yuancheng, "Yuancheng, how are you-"

Liu Dachao's words were only half. It turned out that he found that Qi Yuancheng was still motionless in the posture he had when he was absorbed by the crystal's energy.
