If this is the case, then the big bell given to Cui Si's "Five Elements Chaos Formula" is afraid that the origin is even more amazing, and nine times out of ten, it is a very powerful immortal treasure, which is commonly known as an immortal weapon! This strengthened Cui Si's determination to continue to cultivate the Five Elements Chaos Technique.

Although Cui Si did not plan to change the exercises he majored in, this did not mean that he did not gain this time, in fact, Cui Si's gains this time were also very huge.

First of all, Cui Si solved several problems encountered during cultivation from this vast sea of classics. So that in the future, the cultivation can be smoother. ”

In addition, after Cui Si studied this time, he had a deep understanding of the exercises of various sects. I even saw scrolls commenting on their strengths and weaknesses. In the future, when hostility arises, Cui Sisi can use what he has learned today to suppress the disciples of those sects.

Finally, there are a lot of five spells recorded in these classics, and as a cultivator of the five elements, Cui Si refers to the other five spells. In it, he got a lot of novel ideas, which made him have a new sense of the use of the five spells.

One of the most important points is to use the five spells to set up the formation. In the past, he threw five spells just to seek stability, accuracy, and ruthlessness, and often threw a large piece of it, for fear that others would run away.

However, in these classics, there is a method of using five spells to form a formation, and then attacking. With the blessing of the formation, not only will the power of the five spells be increased, but the enemy will also be easily confused, thus missing many opportunities to escape. Therefore, the Five Spell Array will be the direction of Cui Si's next efforts.

When Cui Si was concentrating on studying the five spell formations, Bing Han'er was not idle, and her "Ice Spirit Divine Skill" was also regarded as the superior mental method of Cuiyu Pavilion, but it was a pity that her cultivation was not enough when she left Cuiyu Pavilion, only the mental method of the foundation building period, and the mental method after Jin Dan did not have a chance to learn.

Bing Han'er originally thought that she would no longer have the opportunity to continue cultivating the Ice Spirit Divine Skill, so she planned to learn another type of ice technique. But she never expected that there would be the mental method behind "Ice Spirit Divine Skill" here, all the way to the void period.

In this way, Bing Han'er could continue to cultivate logically, anyway, there was still a long way to go to reach the Void Realm, so there was no need to worry too much at all.

This harvest alone was enough to make Bing Han'er ecstatic, not to mention that there were still a few ancient scrolls here, which turned out to be the experience left by the masters of the Cuiyu Pavilion who cultivated the "Ice Spirit Divine Skill". After reading those experiences, Bing Han'er's understanding of "Ice Spirit Divine Skill" was further deepened, and in just half a year, she made a breakthrough again and officially became a cultivator in the later stage of Jindan, and her improvement speed has not decreased, I believe that it will not take many years to enter the realm of Great Perfection. And finally hit the Yuan Infant Monk.

Cui Si and Bing Han'er, who got the ancient scrolls, threw themselves on cultivation headlong, completely ignoring the outside world. In their opinion, protected by endless cold winds, they are absolutely safe here.

However, Cui Si and Bing Han'er were obviously very wrong. Soon after they began their retreat and cultivation, some monks came here one after another and began to search the entire Ancient Cold Realm.

The number of these monks is not much, only a dozen people, but the strength is very strong, and all of them are monks above Huahong. They were all dressed in black and robes, with a full body of evil energy, and they knew at a glance that they were cult monks. They all have a white bone claw mark on their chests, and if there are outsiders here, they can know their identity by this mark, and they are the high-ranking monks of the famous super evil sect Black Yin Sect.

The Black Yin Sect is an evil demon sect that is no worse than the Cuiyu Sect and the Chenyue Sect, they are the best at the exercises of the Yin Poison attribute, they are ruthless, and they are extremely vicious, coupled with their arrogant and ferocious temper, making the Black Yin Sect the most unwilling sect in the cultivation world.

It turned out that the castle master of the Ice Castle in the Ancient Cold Realm was born in the Black Yin Sect. He happened to be cultivating the Yin Cold Exercises, and when he was cultivating in the Ancient Cold Realm, he would get twice the result with half the effort, so he was sent here to keep an eye on the relics of the Five Dharma Daoists.

In fact, the reason why the people of the Black Yin Sect knew about this was a complete coincidence. Back then, the five magic spells of the Five Dharma Dao people were too powerful, and they were even stronger than the five spells of the Black Yin Sect that were good at Yin and Cold attribute exercises, and they immediately compared the Black Yin Sect. It made the Black Yin Sect really lose face, so the Five Spells of Chilling Ice naturally attracted their great attention.

As the Black Yin Sect, who is also good at the five spells of the Yin and Cold attributes, they do have a set of the five spells of the Yin and Cold type, after studying the five spells of the Chill and Ice Soul countless times. They unexpectedly discovered that the materials needed to refine this five spells were the unique cold wind of the Ancient Cold Realm. From this, they also judged that the Five Dharma Dao people had stayed in the Ancient Cold Realm for a long time, and it was very likely that one of the old nests was set up here. Later, they were lucky enough to find some traces left by the Five Dharma Daoists, and they all pointed the finger at the Ancient Cold Realm, so the Black Yin Sect sent a Void Monk to sit here.

Originally, they just had the idea of giving it a try, even if they couldn't find the relics of the Five Dharma Dao people, it would be good to be able to gain a foothold in the Ancient Cold Realm.

But they never expected that this move would take a thousand years before it would finally come into play.

After getting the exact information, the upper echelons of the Black Yin Sect immediately sent a Void Cultivator with more than a dozen Huahong Cultivators to this realm to conduct a careful search.

They are all carefully selected monks, and all of them have defensive spirit treasure protectors, which can effectively resist the cold and evil winds, and are more suitable for action in the ancient cold realm.

However, even if the people who are dispatched are all masters, but the Gu Han Realm is so big, for a while, they can't do anything at all. After all, the weather here is very harsh, and even if the cold wind is protected by the spirit treasure, it will consume a lot of spiritual energy, which makes their actions in the ancient cold realm very restricted.

Therefore, these people were very guilty when they searched in the Ancient Cold Realm, and they had not gained anything for a long time, if it weren't for the appearance of the ninth-level demon beast ice dragon, which made them more confident, they might have to give up.

Fortunately, the emperor lived up to his wishes, and after searching for the ancient cold realm for more than half a year, they finally found a place that was suspected to be a treasure hidden, that is, the area surrounded by a large dense cold wind.
