Ding Xing's guess was not wrong, He Xijing did have a private matter to entrust to him.

This matter is not difficult to handle, and it is even quite easy, but it is just to ask Ding Xing to quietly send a letter out when he passes through the territory of the Yusha faction, Ding Xing feels that this is a gesture, so he does not refuse.

He Xijing saw that he received the letter, and when the ship approached the coast, he personally escorted him to land.

There is a long cliff standing on the coastline of the Jade Brake Sect, which is called a 'first-line cliff' by the monks of the Demon Domain, and there are disciples of the Jade Temple guarding every other distance, He Xijing is familiar with the loopholes in the defense line, and flies over the cliff with Ding Xing, and has been going deep into the interior for hundreds of miles, so he said goodbye to Ding Xing.

It was late at night.

Ding Xing was alone in a desolate wilderness, facing the hazy moonlight, watching He Xijing return to the first-line cliff: "Thank you Senior He for escorting, I promise to send that letter to Senior Du!"

He Xijing replied in a voice: "Hey, I don't need your guarantee, I haven't seen her for thirty years, whether she is still alive or not is two words, because you went to the Blood Hidden Gate to pass through her hometown, I asked you to pass the message, if she dies or disappears, you don't have to look for it, just destroy the letter directly, it doesn't matter!"

Ding Xing's 'Du senior', in fact, is an old friend of He Xijing, the couple met in Binghua Mountain thirty years ago, originally hostile parties, but by chance, there was a few days of dew marriage, although there is no name of Taoist couple, but there is the reality of Taoist couple.

The so-called one-night husband and wife are one hundred nights, He Xijing can never forget this woman who once brought him joy.

In fact, He Xijing admired the glamorous appearance of 'Senior Du' back then, and wanted to bring this woman back to the family, but he only had a Xuanfetus cultivation at that time, and the Demon Domain Monk was quite pragmatic, so he felt that he had no ability to protect, so he simply left.

Now that He Xijing has succeeded in marrying Dan and is ranked among the elders of the Cangxia Sect, he feels that his supernatural powers are not what they used to be, so he thinks of 'Senior Du' again.

Originally, He Xijing wanted to look for him face to face, but after all, the two sides had not been masked for 30 years, and the hometown address revealed by 'Senior Du' may not be true, the key is that 'Senior Du' is too weak and loves the strong, and He Xijing has been holding back a breath of anger in his heart.

For various reasons, He Xijing was reluctant to find someone in person.

He entrusted Ding Xing to deliver the letter, in fact, it was just to break a knot, if the 'Du senior' had died, he felt that he would not be sad, even if Ding Xing successfully handed over the letter to the 'Du senior', he should not be happy.

Ding Xing listened to He Xijing's transmission in his ears, and smiled bitterly in his heart, this errand ...... It's boring.

He looked at He Xijing's back and completely disappeared from sight, then he turned around and plunged into the unknown demon realm in the distance.

The seven factions of the Wei Kingdom gather in one country, but the Demon Domain is different, and the six Demon Dao sects here each control a mortal kingdom.

The territory of the Yusha faction is located in the territory of the Yan Kingdom, which has thirteen state capitals under its jurisdiction, and the wasteland where Ding Xing is now located is located in the easternmost Jizhou, and he needs to cross the entire Yan country and rush to the extreme west of the country, so as to enter the land where the Blood Hidden Gate is located.

With Ding Xing's current hurrying speed, if he didn't stop in the middle, he would be able to reach the bank of the Shengteng River in more than a month, but he promised He Xijing to pass through the Yutian Hills of Quzhou in the belly of Yan Kingdom, and he wanted to send a letter to 'Senior Du', and he couldn't predict how long he would stay at that time.

The Demon Realm is not as good as the Wei Kingdom Cultivation Immortal Realm, this is by no means a peaceful paradise, Ding Xing has long heard that the Six Sects of the Demon Dao are sects that are inherited based on masters and apprentices, and there is no Xianzhuang under its jurisdiction, and there is no comfortable garden to find a comfortable garden, and killing and blood can be seen everywhere.

Even if it seems to be an easy messenger errand, it is very likely to encounter a dangerous killing opportunity halfway.

Since landing on the shore of the Demon Domain, Ding Xing has not relaxed for a moment.

Under the moonlit night, there is a vast wilderness.

Ding Xing looked ahead, full of residual trees and dead grass, and the cold wind was constantly raging in the air, sweeping close to the ground, and the grass and trees were undulating.

The sound of 'huhu' sounded like a ghost crying.

The more Ding Xing walked west, the more desolate the terrain became, and when it was dawn, he had traveled thousands of miles, and there were not many people.

This is a plain with a smooth road, if it is placed in the territory of the Wei Kingdom, it is unimaginable, such a suitable area for living in peace, at least a hundred mortal cities can be built.

However, it is sparsely populated here, and there may have been a majestic city standing and mountains and rivers stretching across it, but under the attack of the demon cultivators, most of them have been reduced to ruins.

Ding Xing could smell the faint smell of blood in the air, he couldn't find the source of the blood smell, and looked at the crimson earth, he felt that the smell of blood should spread from the ground.

After waiting for half a month, he rushed to Quzhou, and there was only a depressed feeling of discomfort left in his heart.

Entering Quzhou, Ding Xing clearly noticed that the terrain was undulating, the plains were disappearing, and the Yutian hills, the first stop of his trip to the Demon Domain, were already far away.

As early as when he was on the sea, He Xijing told Ding Xing about the situation of the six sects in the Demon Domain, what boundary the main vein of the sect was built in, and where was the dangerous area where the demon cultivators were accustomed to going, and they all told Ding Xing one by one.

The Yutian Hills are a settlement of demonic cultivators around the main vein of the Yusha Sect, and these demonic cultivators are generally loose cultivators, who pay tribute in exchange for a safe place in the hills.

In order to facilitate the collection of tribute, the Yusha faction specially built a Yutian Fort, and the hometown address revealed by the 'Du seniors' to He Xijing was Yutian Fort.

According to He Xijing, any monk can enter Yutian Fort, even a fresh face like Ding Xing, but he must participate in the fighting held in the fort and win the battle before he can get the right to settle.

As for losing, you will definitely die in the fort.

Ding Xing had heard of the fighting meeting, which was essentially a cockfighting competition in the demon cultivation world, where people or demon beasts were locked in cages and caught and killed, which was an extremely primitive bloody festival.

Ding Xing won't participate, he came to Yutian Fort just to deliver a letter, and he didn't stay too long, his plan was to change his appearance, find a demon cultivator target of Yutian Fort, use skin painting to disguise, and then blend into the fort.

At present, the masters of the Yusha faction are all breaking into the Mohe River, and there is no Jindan monk of the Yusha faction in Yutian Castle, and Ding Xing is mixed in, and the possibility of being detected is extremely small.

He made up his mind and began to lurk in the mountains and forests of the Yutian hills, waiting for an opportunity to find a replacement target.

He originally intended to disguise himself as a monk of the same rank, but he waited for seven or eight days in a row, and did not meet a demon cultivator in the Xuan Fetal Period, so it is estimated that he went to Mohe to hunt for treasures.

At present, the demon cultivators who are accustomed to haunting the hills are all juniors in the Qi cultivation period.

Ding Xing carried a spirit wine that could suppress cultivation, 'Turtle Breath Dispersion', and after thinking about it, he decided to disguise himself as a Qi cultivation period monk.

On this day, he hid in the branch of a hawthorn tree, staring at a young man in black who had returned from other places.

When walking through the mountains and forests, he had a magic weapon hanging on his head, but he turned back in three steps, watching his shrunken demeanor, like a rat crossing the street, for fear of being beaten, and he was very vigilant.

Just as he was about to enter Ding Xing's trap circle, his footsteps suddenly stopped, and he squinted to the side, he didn't sense Ding Xing's direction, but another monk rushed here, he didn't strengthen his guard, obviously old acquaintance with that monk.
