Without any help, Elder Hong had to respond. He had made up his mind that for the sake of the present, he had to spend a lot of money and hire hundreds of people to dig mountains to Yinfen Mountain. Even if the cost was higher, it would be higher, and he would still meet the requirements.

Elder Hong couldn't suppress his curiosity and asked Xu Yi several times what the use of this black yin jade was, but Xu Yi did not answer at all, just said that one sentence has its own wonderful use.

Elder Hong's face turned red with anger. He wanted to leave, but Xu Yi grabbed it again, "Old Hong, don't be busy leaving. My time is so precious. Where is the spirit gathering array? I'm busy practicing here. If I delay, I will die at the hands of Old Demon Zhong, which will be of no benefit to you?"

Before Xu Yi was brought to the chamber of commerce, Elder Hong only felt that this person was gentle and elegant, extremely polite, and had the style of a disciple of aristocratic family.

He just pulled this person into the chamber of commerce and became a guest official. He suddenly realized that this person was simply a mixture of cowhides and shamelessness. He was extremely difficult to deal with, and his words were even more unforgivable. He spit out the words from his mouth, just like spraying venom.

At this moment, Elder Hong was afraid to deal with him, biting his cheek and said, "Brother Xu, why bother to worry? If you write in black and white, you can still regret it. The spirit gathering formation has been prepared long ago. For you, the young master has sacrificed his money this time and has given up his cave."

After half a cup of tea, Elder Hong led Xu Yi to land at a green peak. Suddenly, Elder Hong had a quick token in his palm, but when Elder Hong saw the token swaying, a moss-covered mountain wall suddenly broke open, revealing a vast cave.

Immediately, Elder Hong threw the token to Xu Yi, "The spirit gathering array is here, and the water and food are all ready. Two months later, Hong will come here again." After saying that, without waiting for Xu Yi to answer, he flew into the air, as if he was avoiding snakes and scorpions.

Xu Yi entered the cave and activated the token to close the mountain gate. The mountain gate was closed. The dark cave immediately became bright, but there were many warm jades between the mountain walls. This jade was a natural source of light that had not been extinguished for thousands of years and was mostly used in dark secret rooms.

After passing through a gorgeously furnished lounge, we arrived at the refining room. The layout of the refining room was very reasonable. Not only was there a training room, but also an alchemy room and a weapon room, which were all separated by prohibitions, and the center of the three restrictions was a spirit gathering array.

Compared with the seriously worn spirit gathering array on Lengyang Peak, the spirit gathering array in front of me is much higher, and the jade pendant that forms the spirit gathering array is almost new. It is worth mentioning that there are five jade pendants in Lengyang Peak, and there are seven jade pendants in this spirit gathering array.

After checking the cave, Xu Yi let go of his perception as usual and searched for the entire room.

With Xie Qingfeng's secret technique, the time spent almost half a cup of tea was completed this time in an instant.

As expected, neither Lie Xingkong nor Elder Hong made any moves here.

After searching, Xu Yi sat cross-legged and adjusted his breath for a moment. Seven jades flew out of his palms and fell into the groove in front of the seven jade pendants. The spirit gathering array was activated. With Xu Yi as the center, the spiritual energy gushed. Xu Yi was bathed in the abundant spiritual energy, and his whole body was relaxed. His body was unfolded, his clothes were gone, and his thoughts moved. A medium-grade thunder spirit stone fell into the spirit gathering array.

Xu Yi activated the secret technique in the Xuanting Body Tempering Technique. Seven pieces of spirit stones placed in the groove suddenly shone with light. Seven rich spiritual energy were wrapped in the middle-grade thunder spirit stone under the guidance of the spirit gathering array. In an instant, a blue spiritual energy emerged and rushed towards Xu Yi. Then he added his body and turned into an arc. The next moment, a shocking roar echoed in the cave.

In other words, Xu Yi was extremely conceited with some of his own ability. This ability was not his Fire Gang, nor his infinite sea, nor his strong spirit stone, but his super endurance to pain.

He has tried it one by one since he practiced the Domineering Art, to the devilishization of several times, from the unbearable pain, to the heart-wrenching pain of splitting the ghost, and he has tried it one by one, and he believes that he has no unbearable pain in the world.

Therefore, after obtaining the Xuanting Body Tempering Technique, he devoted himself to studying it. The final conclusion he came to in practicing this set of techniques was exactly: the difficulty lies not in the martial arts, but in the middle-grade spirit stones.

He believed that as long as he got the extremely difficult spiritual stone, this exercise could be completed in one go.

As for the exercises, he repeatedly mentioned that he could not cultivate his cultivation without the later stage of the soul-stricken soul. In the severe pain, the ghost collapsed and if he did not die, he would be crazy. He did not go to his heart at all.

It was not until this moment that the electric arc was added and pierced the acupoints that he realized that there was even more pain in the world than the demon who transformed into a demon and tear the tendons and meridians.

It is said that he has not been able to face the power of thunder. In the past, in the Battle of the Great Yue Empire, he used his body to resist the thunder bombardment led by the Jiuxiao True Dragon Sword, and he did not feel that it was difficult to stop it.

But he didn't know that the body was under the power of thunder and was injured in the flesh. It was not like this when he practiced the Xuan Ting Body Tempering Art. The meaning of thunder was irritating the acupoints. This severe pain can be said to be better than the blunt knife to sharpen the bone marrow.

Amid the heart-wrenching howl, Xu Yi's mind was not at all confused. The magic tricks kept running, and the blue-blind spiritual energy continued to spread, turning into arcs, from Tianmen, Lower Middle Kui, to Hanyuan, and constantly wandering.

However, half a stick of incense, the seven ordinary spirit stones in the spirit gathering array were exhausted and turned into ashes. The medium-grade thunder spirit stone no longer released the meaning of thunder. Xu Yi was already in pain and burst into tears. He fell to the ground, staring at the medium-grade thunder spirit stone that could hardly be consumed. However, he was thinking in his mind: No wonder the martial arts mentioned repeatedly that the medium-grade thunder spirit stone is necessary. It turned out that the thunder spirit stone is not pure enough. Instead, the low-grade thunder spirit stone cannot stop the loss of spiritual energy like the medium-grade thunder spirit stone.

Not just the thunder spirit stone, the difference between the lower and middle spirit stones is, except for the difference in the abundance of spiritual energy, the biggest difference is the self-stop loss function.

Take ordinary spirit stones as an example. Once the Spirit-Spiriting Art is activated, it is impossible to stop the loss by itself and must consume all the spiritual energy.

Xu Yi refined the Wind Talisman for the first time. The spiritual energy of the Feng Ling Stone kept overflowing, forcing him to make the Xun Talisman in time.

Here, using the medium-grade thunder spirit stone is clearly a person who has developed this Xuan Ting Body Tempering Art. Even the strong Yin Zun must not endure it for a long time when the thunder intention stimulates the acupoints.

After practicing for half an hour, Xu Yi barely calmed down his mind and replenished some clear water. Xu Yi almost endured the trembling deep in his soul, sprinkled out seven spirit stones again, and activated the magic trick.

The spirit gathering array was activated again, and the abundant spiritual energy once again wrapped around the entire medium-grade thunder spirit stone. The dark blue spiritual energy rushed towards Xu Yi, and the electric arc intertwined, and the heart-wrenching howl sounded again...
