You must know that judging from his age, let alone Yan Yunzi, even if it is Gu Qiufeng, it is estimated that he must be regarded as his elder. And his current strength to slay the doom will never make this person pay attention to it.

After the white light in Fang Yuchen's hand appeared, the cold light in Gu Qiufeng's eyes suddenly flashed, and he had already seen those three things, a letter he was not familiar with, but the other two things, he was very familiar with.

One is the investigation report he gave to Yan Yunzi at the beginning of the summer festival about the Adventurers' Guild on some areas of the Northern Cloud Plain, and the other is the crystallization made by countless great adventurers of the Adventurers' Guild risking their lives - "The Wind of Bianyun Mountain"!

It wasn't until he heard Imperial Minister's words that the chill in his eyes subsided a little, and was replaced by a slight sense of surprise. Gu Qiufeng frowned and glanced at the hall on the first floor, and said lightly: "You come upstairs with me." ”

Speaking of which, regarding the adventurer's guild's investigation report on some areas of the Northern Cloud Mist Plain three months ago, Fang Yuchen was still a little puzzled.

Yan Yunzi seems to have given him two tasks, one is to carry out the energy replacement of the magic device used to monitor the elemental changes in the northern region of the Cloud Plain, and the task reward is the broken chain that he said excavated from the forbidden demon territory of the Star Underworld Empire, which seems to have an inseparable connection with the "time and space god" of the year. And the other one, it seems to be to find the old man's apprentice Amantina who entered the Bianyun Mountain Range, and the task reward is suspected to be the "six-pole magic" and some skills or something.

And this investigation report, which is mixed with the mission materials, is a bit abrupt. Fang Yuchen had a brief look at the above, it was all Yanhua font, and he could understand it.

This investigation report roughly said that three months ago, not long after Yan Yunzi first came to Xijiang City as the chief scholar, some of the adventurers registered under the adventurer's guild discovered an anomaly in the northern part of the cloud and mist plain.

The Ice and Snow Beasts located in the area of the Cold Misty Lake and the White Grass Forest have become alienated again, becoming more restless.

Originally, after decades of adaptation, the demonic beasts that had mutated in the cloud and mist plains due to the cold snap in the north had formed a stable ecosystem. Such a sudden re-alienation and more restlessness immediately alerted Gu Qiufeng after receiving the news.

He then sent a team of many registered elite adventurers to investigate the area. And the results of the investigation made Gu Qiufeng even more suspicious.

The White Grass Forest is located in the depths of the cloud and mist plain to the north of Xijiang City, about 600 miles. Its topography is relatively special. To the north is a series of cold and misty hills, while to the east is a perennial frozen lake of cold fog. After some investigation of the surrounding area, the adventurers sent by Gu Qiufeng sent back all kinds of news one after another.

Some said that they heard a gust of yin wind howling under the cold mist cliff layer in the west of the Baicao Forest, and some said that they saw a continuous silky black gas boiling on the ice surface of the Cold Misty Lake.

The flow of mana even becomes ineffective here, and sometimes the flow of mana accelerates, overloading the entire circle and making it more abundant, but it can also quickly collapse due to the fragility of the materials used to build it. Sometimes it will suddenly block, causing the entire circle to be dim, and it is impossible to build the power of the circle!

And the whole area has become colder and colder than the surroundings, and even a trace of black gas will appear in the white fog rolling in the air from time to time, and after passing the cold fog cliff layer and the white grass swamp and icy hill area to the south, it is still spreading to the surrounding area.

Such an abnormal situation immediately aroused the suspicion in Gu Qiufeng's heart. He immediately contacted the various magician guilds in Xijiang City, and these mages and scholars who were quite interested in magical elements immediately formed a group and analyzed some of the local materials brought back by the adventurers day and night.

As a result of the analysis, these scholars and mages came up with the closest possible theory.

For unknown reasons, another elemental environmental mutation is taking place in the northern part of the Cloud Plains, which has led to the mutation of some of the Ice and Snow Beasts, and this elemental mutation seems to be continuing.

As for this "unknown reason", the mages and scholars in Xijiang City also have a theory that is relatively close to reality in terms of possibility. That is, a branch of some kind of Ice and Snow Beast has evolved because of migration, or in order to be more adaptable to survival, and finally affected the Warcraft ecological balance circle in the northern part of Cloud Plain. It was this disruption of the balance that led to a chain reaction behind this.

It has to be said that today, when the theory of magic is approaching perfect rigor, the mages and scholars of Xijiang City quickly came to a summary of the causes and consequences of this abnormal situation from some clues.

Of course, if it's just a "antecedent", it doesn't matter to Xijiang City or Bianyun Kingdom. But this "consequence" is likely to be very serious, if the ice and snow beasts mutate again, or even become manic and crazy, it is very likely to trigger a wave of large beasts that have not appeared since decades ago!

The reproductive power of these demonic beasts is definitely much stronger than that of humans, and once Xijiang City, which is in the western part of the border, is swept away by this beast tide, the consequences will be unimaginable!

Therefore, Gu Qiufeng immediately presented the investigation situation in his guild and the research reports of the mages and scholars to the Xijiang City government at the time of the summer festival.

In fact, in the past three months, Gu Qiufeng has not stopped the continuous investigation of the northern part of the Yunwu Plain. He constantly issued guild quests, and sent adventurers to the northern part of the Cloud Plains to record the daily routines of the various ice and snow beast groups. During this period, many adventurers were even damaged.

After the opening of "Chop", players poured into Xijiang City in large numbers, and after the official turn, many players became adventurers, and this thorny problem was solved for him to a large extent. Although the strength of these people from another world is very weak, at least they will not actually die from their injuries, and he can also assign these high-risk tasks to these people.
