Seeing that the speed of the streamer on the white bone ghost king's banner embryo was getting faster and faster, it had exceeded the minimum speed recorded on the refining jade slip, Fang Huairan nodded with satisfaction, as long as there was no mistake in the next sacrificial refining prohibition, it would be a general Tongtian Spirit Treasure.

However, seeing that the white streamer is still brightening and fast, it is estimated that it is no problem to reach the medium Tongtian Spirit Treasure, and even if it continues like this, it is not impossible to refine it into a powerful Tongtian Spirit Treasure.

Most of the days passed, and the joy on Fang Huairan's face became more and more, it turned out that with the addition of all the auxiliary materials, the spiritual light on the embryo had reached the level of refining the powerful Tongtian Spirit Treasure described in the refining jade slip.

When the last auxiliary material was added, Fang Huairan used the silver liquid he had prepared in his free time before as the rune ink, and then used his divine sense as a knife to control the rune ink to depict the prohibition of the white bone ghost king banner on the embryo little by little.

The prohibition of the White Bone Ghost King Banner is the Tiangang Prohibition, as long as the thirty-six prohibitions are carved on the embryo, the White Bone Ghost King Banner will be considered to be successfully refined.

Fang Huairan had practiced the portrayal of the prohibition of the White Bone Ghost King Banner countless times before, and for this reason, he also specially took out a few corpses of different races and refined several imitation spirit treasure-level White Bone Ghost King Flags, and practiced the portrayal of the prohibition on them.

Now that he is portraying again, Fang Huairan does not dare to say that he is at ease, but he can definitely be said to be proficient. It didn't take long for the first Tiangang Prohibition to be depicted, and at this point, the embryo already had the level of a low-level imitation spirit treasure.

Fang Huairan didn't dare to relax at all, and calmly portrayed the second and third prohibitions......

The first eighteen prohibitions were extremely easy to portray, but when it came to the nineteenth prohibition, Fang Huairan felt that the resistance to portrayal became bigger and bigger, after all, with the nineteenth prohibition, the embryo was already at the level of a spirit treasure, even with Fang Huairan's strength as a refining master, it was far less easy to refine than imitating a spirit treasure.

As the prohibitions increased, Fang Huairan's portrayal became more and more difficult, and at this time, Zhou Tong, who received Fang Huairan's message, also paced in gently, standing in a corner of the refining room, quietly protecting Fang Huairan.

I saw that there was more and more sweat on Fang Huairan's head, and the speed of depicting the prohibition was getting slower and slower, and even almost every stroke took more than half a minute to complete.

Zhou Tong, who was watching from the sidelines, couldn't help but sweat for Fang Huairan, Lingbao Zhou Tong saw that Fang Huairan had successfully refined, but Tongtian Lingbao, although theoretically the alchemy master who cultivated during the void period can also refine it, but this first refining, no one can say whether it can be successful.

Fortunately, the White Bone Ghost King Flag, a heavenly spirit treasure, is not necessary for the two, and there is not much pressure on the psychology of the two, it is good to become, it doesn't matter if it doesn't work, it's a big deal that the next interracial war, collect some corpses and refine them again.

When Fang Huairan was studying this refining jade slip before, he joked that this Tongtian Spirit Treasure was estimated to be the most common Tongtian Spirit Treasure, because once a clan war occurred, low-level monks might not be able to collect enough corpses to refine, but high-level monks and Feihong City officials could definitely refine this Tongtian Spirit Treasure level banner.

Moreover, even if it is a low-level cultivator, if there is a refining method, he can also refine the spirit treasure level and imitate the spirit treasure level like he did before.

In fact, in the previous war, the two of them had seen this flag used more than once.

Just when Zhou Tong's thoughts didn't know where to diverge, he suddenly felt the aura of the heaven and earth around him, and hurriedly looked at the mouth of the Floating Light Immortal Yanding.

I saw that the embryo that was originally suspended in Dingkou, burned by Tianfu Ziyan on the one hand, and forbidden on the other, at this time, the white light became more and more abundant, and it continued to release a suction force. It was this suction that caused the surrounding heaven and earth aura to be turbulent.

The suction force is getting bigger and bigger, and the speed of Fang Huairan's carving has become slower, and now it takes at least two or three minutes for each stroke.

In the blink of an eye, more than a month has passed, and the embryo has been like this, the white light has become brighter and the suction power has become larger, and at the same time, Fang Huairan's depiction speed has become slower, and the surrounding heaven and earth aura has also changed from turbulence to agitation.

However, fortunately, the scope of the aura agitation of heaven and earth is not large, and it does not exceed the scope of the entire Frost Leaf Cave Mansion, otherwise it would have been so long, it is estimated that it would have attracted the attention of the Yongxin Palace, which was monitoring the Feihong Defense Area.

At this time, Fang Huairan had also carved the thirty-sixth prohibition, and now it would take at least an hour to complete the portrayal in just one stroke, and the depiction prohibition that had not slept for more than a month, even with his cultivation in the early stage of refining, was extremely exhausted.

Zhou Tong looked at Fang Huairan distressedly, and he was powerless to help, so he could only bite his lip and wait quietly.

Suddenly, Zhou Tong felt the aura of heaven and earth around him shake violently, and then a breath unique to the heavenly spirit treasure swept out.

The breath came and went quickly, and at the moment when the breath disappeared, there was a suction force from the embryo of the Floating Light Immortal Yan Ding's mouth that was no less than that of himself and Huai Ran who had advanced to refine the void before.

As soon as the suction power appeared, the surrounding heaven and earth aura immediately swarmed towards Dingkou, Zhou Tong hurriedly released his divine sense, and through the prohibition of the cave mansion, Zhou Tong felt that the aura of heaven and earth within a radius of more than three thousand miles was attracted.

After thinking about it for a while, he found that there were no other monks' cave mansions within three thousand miles, Zhou Tong was slightly relieved, but such a wide range of aura fluctuations must not be hidden from Yongxin Palace, but there should not be any big reaction over there, after all, they are all well-informed people, and they should be able to guess that it is the master of the Frost Leaf Cave Mansion who refines the Tongtian Spirit Treasure.

The suction did not last long, and when a white aura light cluster with a diameter of more than ten miles was formed in the sky above the Frost Leaf Cave Mansion, the suction force was suddenly retracted, and the previous suction in all directions was changed to a fixed point to suck towards the white aura light cluster.

The white aura light cluster was sucked by the suction, and the lower end was like a funnel, and a long pillar of aura stretched out downward, injecting into the embryo of the white bone ghost king's flag.

Zhou Tong sensed it, the aura of the white aura light cluster was not the same as the common aura of the five elements aura, ice, wind, thunder and other attributes, there was a cold aura, it should be some kind of ghost attribute heaven and earth aura, but he didn't know it.

With a beautiful gaze, Zhou Tong saw that thirty-six Tiangang prohibitions had been carved on the white bone ghost king's banner embryo, and when he turned his eyes again, he found that Fang Huairan had stopped the forbidden sacrifice at this time, and was closing his eyes and pinching the trick to guide the injection of the ghost Dao attribute heaven and earth aura.

The refining of Tongtian Lingbao is different from Lingbao in the aura infusion body, and the aura of Lingbao infusion is not much, so it basically ends without guidance, but Tongtian Lingbao has a lot of aura in the infusion body, if there is no instrument spirit, then it needs the guidance of the refiner.
