"too difficult."

Yu Ziqing looked through some of the replica books he had with him. They were all pure knowledge books.

There are some classics included in the new book list, all of which have been gathering dust for a long time.

The few that are regarded as sects are similar to the Qinglian Sword Code.

This Qinglian Sword Code is the general outline recorded by Yu Ziqing after he drew the sword.

Well, as long as the true meaning of the general outline can be seen, Yu Ziqing's subsequent content is even irritating to his eyes.

Back then, when Han Dong saw this thing, he didn't vomit directly. He was extremely restrained and was too proud.

In the version that Han Dong later completed, it was obviously more than one level higher.

Yu Ziqing held this thing in his hands and didn't practice much, because it requires talent, mind, and will.

The most important thing is that it is time-consuming and labor-intensive. Yu Ziqing is unlikely to be as dedicated as Han Dong, who is devoted to the sword and has been practicing for thousands of years without wavering.

Yu Ziqing also has other good swordsmanship skills, but how good he is at it really depends on the individual.

Fortunately, the book list given by Lao Yang this time does not involve any method, but some knowledge related to swordsmanship. The theory is very in-depth, but it does not require practicing swordsmanship for hundreds or even thousands of years.

This level of difficulty just stuck in Yu Ziqing's mind, and he definitely couldn't learn it in one go. It was much more difficult than before.

But if you work hard and try your best, there is still a high chance that you can master it.

Finally, Yu Ziqing secretly gave himself a shot of chicken blood to encourage himself.

There are more than ten pages of secrets in the book list, and you have to learn everything you need to know.

Especially seeing Lao Yang’s attitude at that time, when he picked up these book lists, he even pinched a few pages.

What he obviously means is that if you feel that a dozen pages is not enough, I will give you a few pages.

Can Yu Ziqing tolerate this kind of thing?

If time permits, he wants them all.

If time does not allow and energy does not allow, then of course, within the scope of ability, choose the stronger one.

After coming out of the extreme cold forbidden area, Yu Ziqing was in no hurry to go back. The classics in his hand were enough for the time being.

His visit to Da Zhen this time can be regarded as three things. One is to come to the Forbidden City of Extreme Cold to chat with Lao Yang and see if he can deal with those fragments of personality.

If it can be dealt with, then it must be discussed with Emperor Zhen.

The first two things have been done, and there is only one last thing left.

Find the fourth guy who has awakened the ancient demon bloodline and there has been no news about it.

The approximate location given by Yunjing is probably north of the Great Earthquake, which is a large area.

Considering that whether it is a major earthquake in the northwest or a major earthquake in the northeast, it is not a very suitable place for human survival at present. The land is vast, the population is sparse, and the environment is harsh.

Especially the northwest area where the earthquake occurred is included in the Forbidden Area of ​​Extreme Cold.

It's really a bit embarrassing for the Riddler to come looking for him.

Find someone, and it's not a particularly urgent matter, and let the Riddlers under you risk their lives.

Yu Ziqing thought it was better to forget it. He was not a devilish boss.

If a great monk comes here, wants to bring a token, and conducts a rough carpet search in this area, it is just overthinking.

Even if you come to the ninth level, your eyes cannot see the faint blue light transformed by those fragments of personality, and you cannot see the extremely cold current, it is not impossible to accidentally fall here.

As he happened to be here now, Yu Ziqing would just come and find it himself.

This time he got the tokens of three ancient demons and used the three to cooperate with each other to locate the bloodline of the fourth ancient demon.

Cloud Whale can sense the fourth one, so the fourth one probably didn't deliberately block the other ancient demon's sensing.

After coming out of Lao Yang's formation, Yu Ziqing headed north.

The three tokens rotated in his palm, influencing each other, but none of them had any special reactions. There were probably none within a radius of a thousand miles.

He walked through the air and continued heading north.

It is cold and quiet here. When there is no extreme cold current, there is not even a cold wind. There is only the faint blue in the sky, like the quiet sea hanging upside down above the sky, undulating slowly.

Yu Ziqing could see it, so he could easily avoid those extremely cold currents in advance, and just search them bit by bit.

From the northwest corner of the Extremely Cold Forbidden Land, go all the way east, walking in a zigzag pattern, sweeping back and forth.

When he swept all the way to the northeastern corner of the Forbidden City, where it connected to the Hengduan Mountains, he looked north again and saw that the north was getting darker and darker.

Even the light reflected by the ice crystals is somewhat unable to illuminate that side.

When he raised his head and looked up, he could also see the faint blue sky, and the edges were slowly shrinking towards the center of the extreme cold forbidden land.

And the Hengduan Mountains, which are like the crest of the earth, continue to go all the way north, disappearing into the darkness of the horizon, leaving only the shadow of a model lake.

Judging from the experience of past lives, if this situation occurs in the extreme north, it will enter the polar night area.

But it was obviously not the case here. Yu Ziqing was once at the Cliff God King, and from the perspective there, he looked back and saw the entire world. This place was originally dark.

In other words, this place is also affected by the unfinished evolution of this world. The further north you go, the more blurred and chaotic it becomes.

When the chaos of emptiness reaches its extreme, it reaches the void.

Yu Ziqing raised his head and looked at the faint blue border above his head, which slowly retracted. He pondered for a moment, then took a step forward and continued heading north.

From here, continuing north, the already thin spiritual energy begins to plummet.

After only advancing a few dozen miles, the spiritual energy concentration, activity level, etc. were only one-third left. As we continued forward, the decline became larger and larger.

There is only coldness left, and it is the kind of coldness that is empty and empty, with nothing in it.

The skylight is getting darker and darker here, and that unique feeling of everything being dark as far as the eye can see is not much better even if you look back to the south.

The sense of direction will also be distorted here, and the deeper it goes, the more serious it will be.

Yu Ziqing frowned slightly. After only advancing a few hundred miles, the surroundings were already so dark that it looked like a starless and moonless night. The divine light in his eyes was shining, but he could not see very far.

This is a bit like the endless darkness under the mountains and abyss.

He stretched out his hand, and the three tokens were spinning in his palm, still unchanged.

He judged the direction, took the token, turned east, and entered the Hengduan Mountains.

Unexpectedly, just ten miles after he entered the Hengduan Mountains, the three tokens lit up at the same time, and the speed of their rotation suddenly increased.

Judging from this range, it is definitely not just entering the sensing range, but already within five to six hundred miles.

Yu Ziqing thought for a while and retreated ten miles to the west. After exiting the Hengduan Mountains, the light of the token dissipated in an instant, and there was no longer any response.

Yu Ziqing looked thoughtfully at the Hengduan Mountains that stretched from north to south and disappeared into the darkness all the way north.

I'm afraid this mountain range also has a big problem.

This is the only mountain range that can still stand on the ground after penetrating into the Arctic ice sheet.

Now it seems that the Hengduan Mountains not only rely on their huge size to block the power of the extreme cold forbidden land, but also have some mysteries in them.

He entered the Hengduan Mountains again, and the token produced a response. Everywhere he could see, there was ice and snow that had not melted for thousands of years.

This place is already much further north than the northernmost part of the earthquake territory, and inside the Hengduan Mountains, looking north, although the north is still getting darker and darker, the range that can be seen is much farther than outside.

.

This confirmed Yu Ziqing's guess.

When I raised my head and looked around, I could still see the edge of the blue sky in the distance.

Yu Ziqing probably understood why others couldn't find him when they came.

This place should have been covered by the faint blue sky before, coupled with the weird shielding power, most people would have to enter the Hengduan Mountains, go all the way north, go deep beyond the northernmost range of the earthquake, and continue northward.

, otherwise it would be impossible to sense it.

There are mountains of icicles here, and their color is dark blue, all of which are serious ten thousand-year-old black ice.

There are also a large number of traces left after the outbreak of extreme cold currents on these ten thousand-year-old black ice, proving that this place was once a zone with high incidence of extreme cold currents.

Yu Ziqing stretched out his hand, flicked his fingers, and knocked on a thousand-foot-high dark blue iceberg. The texture was extremely hard, at least several levels higher than refined black iron.

If you take it back from any mining point, you can sell it at a high price.

It's just that the mining difficulty is a bit too high.

Yu Ziqing did not do anything rashly. He continued to move forward according to the guidance of the tokens. Only more than four hundred miles eastward, the three tokens were already completely enveloped in brilliance.

It proved that the target was very close to him, definitely within ten miles.

He kept adjusting his position and searched twice within a radius of ten miles, but found nothing.

Even when his Yangshen opened his eyes, he found nothing.

He threw the three tokens in his hand and let them fly in three directions respectively. The shining tokens rotated for several miles nearby, and finally spun around a dark blue iceberg.

Yu Ziqing glanced down and saw that he had found the right place, it was right here.

Taking back the token, he brushed away the snow covering the iceberg, revealing the translucent black iceberg below. Under the divine light in his eyes, he could vaguely peek under the iceberg, as if there really was something there.
