Everyone in the Yun family was very surprised by the appearance of this barrier. But since the barrier began to spread from the patriarch's seclusion room, they didn't question it further.
After the boundary was established, Yun Chen began melting all the material separately at the same time inside the furnace. Each material melting temperature was carefully controlled by him. It took him only four hours to refine them completely. He merged some of them together like the medium grade spirit stones, the emperor's essence crystals, the soul-refining stones, the bloodline enhancing flowers, the demon cores and other refined materials while others were used separately like the gold true essence or the undying fire ore. Slowly, a thin orange-colored silk dress appeared on the puppet followed by a golden breast plate, scarlet boots and gauntlets with wings garments, a two-colored black and golden belt inlaid with twenty blue stones. Those blue stone were in fact space stones and each one of them has a space of 10.000 m3. Finally, Yun Chen crafted a crystal-like golden helmet that can be adjusted to Su Ling's hairs. After the armor was finished, it didn't trigger the heavenly lightning which means that the concealing formation was very effective.
«For the moment this armor is only the quasi-heaven tier. It will truly step on the heaven tier after absorbing the heavenly energy from the heavenly lightning. It is time to give shape to the other weapons. » Yun Chen said after burning the stone puppet to ash leaving only the armor floating in the air.
He then put the armor on the side and poured the refined materials that were left insides some holes corresponding to the weapons that he wanted to craft. For example, for the sword-whip, there were four holes. One for the blade's material, one for the guard's material, another one for the grip's material and the last one for the chain's material that will be inside the blade to transform it into a whip. On each weapon's mould, there were also elaborated formations allowing one to change the shape of the different parts on the weapon. After choosing the shape of the two other weapons, Yun Chen only needed to continuously pour fire inside the furnace. Six hours later, the weapons were automatically freed from the moulds. They were all quasi-heaven weapons.
«All the weapons are ready. It is time proceed with the Universe merging fluid. » said Yun Chen before taking out the box made from dark iron.
He then began cracking the formation sealing the transparent bottle. In less than five minutes, the formation faded away and Yun Chen guided the Universe merging fluid out of the bottle using his soul power. In addition to the box containing the Universe merging fluid, he also took out the two bottles of pure phoenix blood, and the two bottles of bottle of the heart blood from the transformation realm black flame salamander and of blood essence from a nine-headed hydra that he didn't use while crating earlier.
Yun Chen crushed the bottle black flame salamander's heart blood and one bottle of phoenix pure blood. He then, mixed them together using his soul power and divided it into four parts corresponding to the armor and the three other weapons. He vaporised the mixed blood on each one of them before enveloping them with his fire. Slowly, the blood fused with the armor and the weapons. One hour later, all the blood completely disappeared inside the armor and the weapons. He then mixed the Universe merging fluid, the second bottle of pure phoenix blood and the bottle of nine-headed hydra's blood essence. He refined it using his fire.
«The particularity with the universe merging fluid is that, when you are refining it, it will extend itself infinitely in order to accommodate the things you want to store inside it before slowly shrinking. » Yun Chen declared while refining the mixture.
Surprisingly, the bloody mixture's volume began to increase rapidly and about ten minutes later, its height was around three meters with a size of one meter radius. It had the same shape as a giant egg.
«Now is the time to incorporate all the weapons! » Yun Chen shouted before digging a large hole inside that imposing mass.
He then put the armor and the three other weapons inside that hole. That hole began to slowly close, and that mass's volume didn't increase. On the contrary, even if it was not visible to the naked eyes, it was slowly shrinking under the refinement of Yun Chen's fire.
«This is the last step before crossing the heavenly lightning. It will be finished when its height and size will be equal to that of a thumb. And, at the speed it is going, it will take at least three days. » Yun Chen sighted after noticing that the giant blood-colored mass was shrinking.
For four days straight, Yun Chen refined the giant mass and now, it is like a little egg the size of a thumb. Moreover, it lost its liquid form and was now like a bloody red gem.
«It is time for this thing to cross the heavenly lightning. I will also use the heavenly energy in the lightning to stabilize the undying the undying fire that I put aside. » Yun Chen after stopping refining the gem and taking his furnace back.
Yun Chen slowly headed outside and went to the principal where Su Ling was training while her master was observing her techniques and pointing out some of her flaws. They immediately stopped after seeing Yun Chen coming toward them. Yun Chen finally arrived beside Su Ling's master and greeted her.
«Greetings, elder sister Meili! » Yun Chen politely greeted her.
«There is no need for these formalities. Have you finished your business? » elder Meili asked with curiosity.
«…no! That is why I came here to see you and ask for your help. » Yun Chen hesitated a little before asking.
«Oh? What do you want from me? If it is within my capabilities, I will help you since you said it was for my disciple. » replied the surprised elder.
«Then I won't be polite anymore! I want you to erect a formation for me. » Yun Chensaid with a firm voice.
«A formation? But, I am not a formation master. It would be very difficul…. » elder Meili was saying with a little disappointment.
«I only want you to activate it using your qi. I already engraved the formation on this jade plate. You only need to inject enough qi inside to activate it. I don't have enough qi for that since I am only at the spirit-gathering realm. » Yun Chen interrupted her.
«Alright! I can do that. But what do you want to do with it? And when do you want me to activate it? »
«I want to activate it right now! As for what I want to do with it, it is use the heavenly lightning energy! » Yun Chen said seriously.
«What? Do you think you can trigger the heavenly lightning with your spirit-gathering realm? That is impossible! » elder Meili shouted.
«Yes and no! » Yun Chen replied with a smile.
«What do you mean? » asked elder Meili confused by this answer.
«I can trigger the heavenly lightning, but it is not my cultivation that triggers it but those things. » Yun Chen said while taking out the bottle containing the undying fire and the bloody red bed.
«This… » elder Meili was very surprised.
She immediately recognizes the undying fire and even she didn't know what that red gem was, since the spiritual fluctuations from it could affect her soul, it is not an ordinary thing.
«I wanted Ling'er to use this fire to fill her element space, but it is too weak right. I barely succeeded in stabilizing it. But if it absorbs the heavenly energy, it can be fully restored, and it would be the best fire for Ling'er. As for that bloody gem, it is another gift to her. You will see when it is finished. » Yun Chen explained.
«Alright! Let's begin! I really want to see how you can trigger the heavenly lightning with it. » said elder Meili to taunt Yun Chen.
Elder Meili injected about one fifth of her qi inside the jade plate before it was activated. A giant formation circle appeared in the sky and covered the whole city. At the center of that circle, there were two empty little circles. Using his soul power, he directed the undying fire without its bottle and the red gem to fill those holes. He then, disactivated the concealing formation and waited for the show to begin.
