Zhenhaiguan is located in the border of the Western Regions, built by the mountain, because the Cangshan mountain rises and falls like the sea, so it is named.

In order not to shock the world, Song Yun and his entourage did not enter the customs, but descended the flying car early, and walked to the sentry pavilion twenty miles outside the town customs.

Xu Changsheng is nearly fifty years old, with a Chinese face, a rough appearance, wearing civilian clothes, his hair is messy like a lion, but his speech and demeanor are very polite.

After a few words of greeting, Song Yun asked about the Kunlun disciple who was lost in the miasma leaf forest, and Xu Changsheng called a partial general named Ouyang Quan and asked him to come one by one.

Ouyang Quan had seen that immortal master, he claimed to be surnamed Yao, from Kunlun, dressed as a layman, carrying a long sword, medium build, big belly, a scar on his right cheek, extending from the tip of his eyebrows to his cheekbones, about a year ago, he appeared in the town customs, when the hussar general waved his troops to fight the thief, not in Guanzhong, Ouyang Quan received him, at his request to collect a batch of rare medicinal materials, spent a lot of silver taels, before leaving, he also asked Ouyang Quan for a map of the miasma leaf forest.

Yao Xianshi went and there was no news until half a year ago, when the caravan from outside the country passed through the miasma forest, and happened to meet a group of monkeys, grabbed a sheathed long sword, chased and played with each other, and the porter became curious, teased the monkey with a few oranges, and deceived the long sword. The head of the caravan was a knowledgeable man, and recognized the seal script on the scabbard as the word "hook and sickle", and knew that it was a good sword, so he spent some silver to buy it from the porter, and when the caravan entered the town customs, he gave the sword as a gift to the chief, and went around a few circles, and finally fell into the hands of Ouyang Quan.

Ouyang Quan speculated that Yao Xianshi was trapped in the miasma forest, something happened, and he couldn't even keep the sword, he hurriedly reported the matter to the hussar general, Xu Changsheng sent someone to Deng Yuantong to send a message, and passed the news to Kunlun.

Xu Changsheng handed over the sword to Song Yun, Song Yun glanced at the seal book on the scabbard, and knew that the fallen disciple must be Yao Jiang, and he was the only one who used the flying sword in the upper and lower parts of the Hook and Sickle Sect.

After a moment of silence, Song Yun asked Ouyang Quan for the name and quantity of that batch of medicinal materials, and asked him for a copy of the same miasma leaf forest map. Ouyang Quan was a shrewd man, not only prepared the map, but also marked the location where the caravan encountered the monkeys.

Song Yun took the map and said to Xu Changsheng: "This incident has bothered General Xu, and General Xu has a capable subordinate. ”

Ouyang Quan was flattered, Xu Changsheng smiled slightly, he did this matter very carefully, and being able to get in touch with the Kunlun faction was very beneficial to the young son's future in Xiandu.

Song Yun put away the map and said goodbye to Xu Changsheng, Deng Yuantong ordered Xu Li and Xin Laoqi to follow the hussar general back to the town customs to wait, Xu Li Boss was reluctant, and wanted to follow to see the excitement, before he could speak, Xu Changsheng coughed, and he immediately looked like a wilted flower - he was really afraid of this father.

Deng Yuantong also has his own considerations, first, Xianfan is next way, Xu Changsheng and his son have not seen each other for three years, and they will get together for a few more days if they have the opportunity, and after returning to Xiandu, they don't know when they will be able to meet, and secondly, Miasma Yelin is only afraid that there is something dangerous, this nephew's cultivation is too bad, so it is better to take him out.

Xu Changsheng took his personal guards back to the town customs, Deng Yuantong saw them go away, remembering that Xu Changsheng and his sister were newly married Yan'er, galloping on the grassland outside the customs, and he was really a little embarrassed in his heart. How many years ago was that old? My sister was frail and sickly since she was a child, and she was not suitable for childbirth, but she was unwilling, and died after giving birth to Xu Li, and now, the pines and cypresses in front of the tomb are already very thick.

Song Yun pulled the long sword out of the sheath and looked closely, only to see that the sword body was spotted, covered with green rust, the blade was like a jagged tooth, and the brilliance was uncertain. She sighed and said, "This is Senior Brother Yao Jiang's Green Rust Sword, and Senior Brother Yao is Senior Uncle Lu's disciple. ”

Deng Yuantong's heart sank, the Lu Shibo she was talking about was Lu Ping of the Hook and Sickle Sect, one of the elders of Liushi Peak, with a high position, it is said that he once competed with the Ziyang Dao people for the position of the head of Kunlun, and was defeated under the Qingying Sword.

"The medicinal materials collected by Senior Brother Yao include Stanley Gum, Danteng, Bone Yellow, Jiuyin Grass, and Catfish Dragon Whisker, which is the main medicine of the synthesis of Wu Ma San, Wu Ma San has a miraculous effect on the snake Jiao, second only to the requiem incense, what Senior Brother Yao is plotting is probably a monster such as the snake Jiao. Song Yun unfolded the map, pointed to the location of the monkey group, and said, "It's better to take a look here first, the green rust sword was found by the monkeys, maybe it's a clue." ”

The hand-drawn map is crude, with only a rough outline of the perimeter of the miasma-leaved forest, shaped like a broken leaf, and the place that Song Yun is pointing to is at the edge of the petiole.

Deng Yuantong took Song Yun's horse as the leader, and the four of them still flew in the direction of the miasma forest in the cloud car.

The miasma forest is thirty miles west of the Zhenhaiguan, it is a dense forest full of rotten leaves and fallen fruits, the miasma is overflowing, the people are inaccessible, there are occasional monkeys on the periphery of the forest, what is hidden in the depths, even the border army stationed in the Zhenhaiguan is not clear.

As early as more than 10 years ago, there were several foreign hunters who did not know the depths, and went into the miasma forest to hunt together, and never returned, in order to appease the people's hearts, the hussar general sent a team of sergeants to search for the whereabouts of the hunters, and they also never returned, and since then the miasma forest has become a forbidden place for the local people to hear the wind and change.
