The mud crater of Dushanzi Mountain Pass is a small col surrounded by high cliffs, and only a narrow path leads to the col at the mouth of the pass. The col was silent, and only the whistling of the wind against the cliff could be heard.

The sound of horses' hooves sounded, and more than a dozen horses galloped into the mountain pass, led by a guide, followed by Su Wu, Peony, Liu Biao, Zhou Yi and other seven brocade guards. Su Wu stopped his horse, looked around, and sighed: "What a hidden place!" No wonder Li Guangli wanted to store the items that had been transferred to the Huns here. ”

Peony said: "It's a shame that they can find this kind of place." ”

Su Wu turned over and dismounted, and asked the guide beside him, "How far is it from Black Oil Mountain?" ”

The guide said: "About a hundred miles." My lord, I didn't say you, how did you think of coming to this place? Although this is the protector of my Western Regions, it is a place where the Huns often haunt, in case we encounter the Hun cavalry, then, then we can ......."

Su Wu smiled and did not speak. Peony pulled the guide: "Okay, don't be endless, go, accompany me over there to have a look." With that, the two walked into the distance.

Su Wu's eyes looked around, and there was a wooden shed standing on the mountain wall, which had been blown away by the strong wind, and the roof of the shed was gone. Su Wu walked over, a pair of eagle eyes searching around—collapsed poles, hay all over the ground, a few broken sacks...... Su Wu walked over, picked up a sack and looked at it carefully, the sack had the words "Second Master Transfer Envoy" written on it. Su Wu raised his head, and suddenly, a piece of black exposed in the straw attracted his attention. He walked over and brushed away the hay, which turned out to be a torn glove, covered in dust. Su Wu dusted it gently, and then opened the sheepskin cover and looked inside, there were a few words vaguely printed on it, and Su Wu carefully identified it. After a while, he slowly raised his head.

Peony rushed in from outside: "Senior brother, what did you find?" ”

Su Wu said: "This is where Helian Wu said that Li Guangli was stockpiling and transferring materials. ”

Peony nodded. Su Wu pointed to the ruts on the ground and said, "And the shaman envoy led by the Yuling girl loaded the supplies from here onto the carriage and went west along the path in front to deliver the military supplies to the Xiongnu army. ”

Peony said angrily: "This Li Guangli is really a great crime!" ”

Su Wu pointed to another rut and said, "But, you see this rut, it's heading south......"

He looked up to the south, and the mountain road ran southwest into the distance. Su Wudao: "The Xiongnu army is due north, but why is this rut going south?" ”

Peony was stunned: "To the south? ”

Su Wu beckoned, and the guide ran over quickly. Su Wu asked, "What is the place to the south from this valley?" ”

The guide replied: "Ah, it is Bayingou, which is the boundary between the Xiongnu and Wusun. ”

Su Wu nodded and instructed Peony: "You ask Liu Biao to pack up the things here and bring them all back to Luntai." ”

Peony promised to walk quickly. Su Wu took the broken gloves in his hand and walked out of the wooden shed.

King Kong Zhou Yibao: "My lord, I found a workshop behind the slope in front!" ”

Su Wudao: "Workshop? Let's go, go and see! ”

About half a pillar of incense, they came to this workshop. The workshop floor is full of black oil and soil, more than a dozen large iron pots, a few have been broken, the rest are residual black oil sludge, a pungent smell of smoke oil is permeated, and the stove fire has been extinguished for more than a month.

Peony said: "Senior brother, what is this workshop used for?" ”

Su Wu pondered, "Oh. ”
