Li Fengyun smiled, scratched his head and said, "The world is so big, there are some things I don't know, and it's not strange." What exactly is that Taihang Bacheng?"

"Taihang Mountain in the east-west horizontal valley, also called '陉', from south to north, there are Yiguan 陉, Taihang 陉, Bai 陉, Fukou 陉, Jing 陉, Flying Fox 陉, Pu Yin 陉, military capital 陉, etc., the ancient name of Taihang Eight Mountains. Gongsun Wuwu explained, "The first is Yiguan, which was the main road connecting the capital Luoyang of the Three Jin Dynasty and other vassal states during the Spring and Autumn Period and the Warring States Period. Yi, is the Wei city during the Warring States Period, the beginning of the Yiguan is in the west of Jiyuan County, the Guandang Kongdao, because of the Yiguan. The last pass of Yiguan is the Iron Bell Pass, the situation is precipitous, and it has been the place of soldiers since ancient times.

The second is Taihang Cheng, which is more than 30 miles northwest of Qinyang, and is only three steps wide and more than 40 miles long. Go to Taihang along the north of Shan, on the Taihang Mountain in the south of Jincheng, the relevant name is "Taihang Pass". It is also known as Tianjing Pass, Xiongding Pass. The situation is majestic, and it is known for its natural danger. From this, you can go straight to the Tiger Prison Pass in the south, and it is one of the key points of the Central Plains.

The third is Baicheng, about 60 miles east of Lingchuan. The total length is more than ten miles, the width is less than one zhang, and it is composed of two parts: seventy-two turns and the ancient plank road. According to this, the Yellow River can be crossed in the south to attack Kaifeng, the east can attack the Daimyo, and the north can peep at Anyang and Handan, which is an important place that can be attacked and defended since ancient times.

The fourth is Fukou Mountain, located in Fushan, the ancients said: "From this east out of Ci, Xing, you can help Zhao and Wei." ’

The fifth is Jingcheng, also known as Tumen Pass, which is located in Jingcheng Mountain. The position is very important.

The sixth is the Flying Fox, also known as the Flying Fox Mouth, which is located in the north of Laiyuan County and the south of Wei County. Two precipices stand steeply, a line of micro-communication, winding for more than 100 miles. The ancients: Standing on the flying fox, strangling the back, entering the secluded and swallow, the most victorious place.

The seventh is Puyin. On the West Bauhinia Ridge in Yi County, there is Bauhinia Pass, also known as Zizhuang Pass. Its peaks and peaks are steep, and it is a military key pass directly to the east of the river.

The eighth is the military capital. Juyong Mountain in the northwest of Youzhou, the ancient name is Jundu Mountain, so the military capital is also called 'Juyong Pass', because it is named in Juyong Mountain. In ancient times, it was called the military capital pass, the Northern Qi Dynasty called the payment pass, and the Tang Dynasty called the Jimen Pass. Its strata are stacked on top of each other, the situation is majestic, the cliffs are sandwiched, the huge stream is in the middle, the strange and dangerous sky opens, and it is called the pass in ancient times. This is the throat road of the ancient Yan into the north of the Jin Dynasty to the outside of the Saiwai.

Of course, Taihang Mountain stretches for thousands of miles, and there are always some little-known trails that communicate things and things, and there will never be only these eight mountains, such as this Tiger Leaping Gorge trail. However, because of its key location, it can transport a large number of people, horses, grain and grass, so it is valued.

But the narrowest part of the Tiger Leaping Gorge is only allowed to pass through by one person, and it is unknown and full of gravel, and the horses can't pass the weight, so the importance is naturally much worse. The Liao people did not know this way, and it was reasonable that they did not send people to defend it. ”

Seeing that they were about to enter Hedong and no longer run around like a lost dog, the three of them were in a much better mood, talking and laughing, and stepped into the Tiger Leaping Gorge.

"Sure enough, someone is here!" The Changbai old monster had already lurked at the mouth of the Tiger Leaping Gorge, and Li Fengyun and the three of them were discovered when they stepped into the Tiger Leaping Gorge, and the news was quickly sent to the hands of the Changbai old monster lurking in the canyon.

"Why are there only three of them?" asked Elder Peng in a low voice, Elder Peng's original name was Peng Hai, he was originally a Jiangyang thief in Hebei, he was fierce by nature, and he had a good relationship with the Changbai Old Monster. Just because he once served as an elder in a large gang, people who were familiar with him in the rivers and lakes called him Elder Peng. When the Khitans invaded the Central Plains, Peng Hai saw the wind and took refuge in the Khitans.

The Changbai Old Monster also felt a little strange, thought about it, and said, "Maybe it's just a pathfinder, after all, Li Fengyun is careful by nature, and Yan Wushuang is seriously injured." Elder Peng, you tell them, stay and take a look, don't do it lightly, if it's a small role, let them go, so as not to startle the snake. If it is Li Fengyun or Yan Wushuang, it must not be let go. ”

Elder Peng nodded and explained.

After about a stick of incense, three figures turned out of the canyon, and when they saw that they were about to enter the ambush, they suddenly stopped. Although the light in this Tiger Leaping Gorge is dim, it does not have a great impact on a first-class master like the Changbai Old Monster.

"There is a murderous aura!" Li Fengyun suddenly felt that the hairs behind his back stood up, and he shivered, and hurriedly grabbed Gongsun Wuwu and Su Yunong, and said in an inaudible voice, "Brother Wuwu, there is a problem here, there is an ambush by a master, you protect Yunong and quickly withdraw from this Tiger Leaping Gorge." It's very bad for us to fight here. I'll see if I can hold back the people who ambushed us. ”

After that, Li Fengyun suddenly laughed, pinched his throat and said: "Brother Sun is right, Li Fengyun is too cautious in doing things, such a steep canyon, if there was an ambush, it should have jumped out a long time ago, why wait now? Brother Sun, the two of you go back and tell General Li, just say that there is nothing in the canyon, let him and Yan Daxia come in! I will continue to explore the way, if there is something, I will inform you." ”

Su Yunong and Gongsun Wuwu understood that they knew that Li Fengyun was extremely sensitive to danger, and he said that there must be a problem here. The terrain of this Tiger Leaping Gorge is too dangerous, if people are blocked in this canyon, even if they have great ability, they may not have a chance to rush out.

In particular, Su Yunong's martial arts skills are not high, and he has repeatedly escaped from the siege by relying on the silkworm armor on his body, as well as the care and protection of Li Fengyun and Gongsun Wuwu. If they were surrounded in this Tiger Leaping Gorge, Li Fengyun and Gongsun Wuwu might still have a chance to escape, and Su Yunong had almost no hope of escaping.

"That's it, Brother Yun be careful!" Gongsun Wuwu pretended to arch his hand towards Li Fengyun, pulled Su Yunong, turned around quickly, and ran towards the Tiger Leaping Gorge.

Elder Peng, who was ambushed in the Tiger Leaping Gorge, pulled the Changbai Old Monster and asked in a low voice, "Changbai Old Immortal, do you want to attack, those two boys are going to run away." ”

"What's the hurry?" the Changbai Old Monster glared at Elder Peng, "Didn't you hear that guy say that Li Fengyun and Yan Wushuang are behind? Catch three insignificant pawns and let Li Fengyun and Yan Wushuang go, this deal is not worth it." Hold your breath and look at what that guy surnamed Yun is going to do!"

Seeing that Gongsun Wuwu had already protected Su Yunong and turned to leave, Li Fengyun walked forward three or five feet slowly, suddenly sat on a big bluestone, untied the gourd around his waist, poured a sip of water, and said to himself: "What kind of days are you called this, you can't eat enough, and you have to sleep with one eye open, I knew this was the case, so I didn't go to this troubled water." Take a break, when it's time to be lazy, you have to be lazy! Combining work and rest is the right way. ”

Then there was a sigh of mourning, and he sat there, refusing to move forward.

The Changbai old monster faintly felt that something was wrong, and thought about the situation just now several times, and suddenly his heart was shocked, his face changed sharply, why did he need the two of them to go back to report the news? Moreover, how could there be such a coincidence in the world, seeing that he was about to step into an ambush, and suddenly the three of them left two people, which was obviously aware of the ambush. And what this surnamed Yun did was like delaying time, and the Changbai old monster hurriedly said: "It's not good, you've been fooled! Everyone hurry up, catch this surnamed Yun first!"
