When Liu Yin heard this, he urgently asked for details, and the errand who came to report was reported according to the truth, Liu Yin nodded, since Zhang Le had rushed to the Chencang Road crossing, and he was in charge of the pursuit operation, Liu Yin was not too worried, and turned back to Lu Xun and said: "Captain Lu, there are some situations at the Chencang Road crossing, so I will leave first." ”

Lu Xun also heard this, so he said, "Do you want to send some people to assist Liu Youcheng?" ”

Liu Yin shook his head and said: "The Wei State spies are cunning, although their whereabouts are exposed at the Chencang Road Pass at the moment, they may not have other plans, so let's do it, there are many people from the Lieutenant's Mansion at the Chen Cang Road Pass, and it is not difficult to deal with it. ”

Lu Xun arched his hand and said: "Okay, I will go here and discipline the Wei State spies and have nothing to hide." With that, Lu Xun turned his horse's head and led his troops towards the mouth of the valley.

Accompanying Liu Yin is now only the main Bo Chen Shou, Liu Yin hit the bridge immediately, crossed the water and looked at the Chencang crossing. The bridge was not long, Liu Yin was fast, and he quickly boarded the north bank, and when he turned around, he found that Chen Shou was far behind, looking at the surging water while walking.

"Chengzuo, what are you thinking?" Liu Yin saw Chen Shou's thoughtful appearance and asked.

Chen Shou said in a deep voice: "Don't you think this matter is a little strange? ”

"What do you mean by that?"

"Why did the spies of the Wei State suddenly appear at the Chencang Road crossing, this matter is quite suspicious, Hanzhong leads to Guanzhong, all roads can be taken, the Wei State spies do not take the meridian road, but they are willing to seek the near and far, take the Chencang Road to the west, and so easily exposed the line of hiding, something is abnormal, and I suspect that the blue bird has other plans."

Liu Yin nodded, he had just sent Lu Xun to bring people to reinforce Fu Luo Dao and Meridian Valley in the Slope Valley, so he had this intention. "Cheng Zuo thinks that the blue bird has the possibility of striking the east and the west, and I also have this intention, so I sent Captain Lu to guard the mouth of the Xiegu Valley, the mouth of the Fu Luo Valley and the meridian crossing, even if the blue bird wants to find a breakthrough from these two roads, it is not easy."

Chen Shou watched the water flow eastward, and said, "Lord Youcheng seems to have neglected one place. ”

Liu Yin raised his eyebrows and said, "Where?" In the past few days, Liu Yin has been exhausted, and he can be said to be racking his brains in the defense of various passes, Chen Shou said at this time that there are still loopholes in his defense, which made Liu Yin secretly taken aback, and asked anxiously.

Chen Shou smiled slightly, pointed his finger at the rolling eastward water, and said, "My lord seems to only pay attention to the checkpoints on the land route, and the investigation on the water route seems to be lax. ”

The water goes all the way to the east, flows through Nanzheng Lecheng, and flows to the Shangyong counties downstream, and the three counties of Shangyong have become the control area of Wei since Meng Da's rebellion, if the Wei spies take the waterway, they can easily transmit the information to Shangyong, from Shangyong to Guanzhong through Wuguan, it will not delay too long, obviously, this road will also be an important channel to prevent the spread of Wei spy intelligence.

Of course, compared to the North Road, the importance of the East Road is secondary, Liu Yin has been arranging the defense focus on the four valley roads of the North Road during this time, but he also did not ignore the defense of the East Road, Zhao Zhuo led people to garrison the Golden Pass, the purpose is to intercept the eastward escape route of the Blue Bird.

After listening to Chen Shou's words, Liu Yin nodded and said: "What Cheng Zuo said is extremely true, although Zhao Zhuo is in the Golden Pass, the defense of the waterway is still relatively weak. Whoever comes, go to the Golden Pass and inform Zhao Duwei, and tell him to pay close attention to the defense of the waterway, and strictly search the passing ships - no, pass on my order, order Zhao Zhuo to intercept all passing ships, prohibit all passages, and wait until the Wei spies are really intercepted, and then let them go. ”

The reason why Liu Yin suddenly changed the order was that he thought of the difficulty of searching on the waterway, the search on land can be searched, and it is difficult to pass the checkpoint inspection with the general entrainment, but on the waterway, the hull is huge, and it is almost an impossible task to search a ship, and the only way is to detain all the passing ships, regardless of whether these owners oppose it or not, before catching the blue bird, the information must not be leaked.

The messenger took the order and left, and Liu Yin and his entourage also hurried to the Chencang crossing.

The woodcutter was actually a spy of Wei, which completely subverted Shi Chang's three views, originally it was just a flood of sympathy, Shi Chang just wanted to help the wood-cutting man, but he never expected to almost send the Wei spy away, and almost made a big mistake.

As soon as he thought of this, the back of Nashi's long spine was cold. Zhang Le has already taken people to the spy, and the responsibility of defending the Chencang crossing still falls on his shoulders, but this time Nashichang's sympathy has long disappeared, no matter how much business travel in the past has been exhausted or even tears are dry, Nashichang is no longer moved, and the iron mask is selfless to hold the Chencang crossing, and even a bird does not want to fly over again.

Liu Yin rushed to the Dujiaping checkpoint, and a lot of travelers had already gathered outside the checkpoint, all of whom were blocked outside the Chencang crossing, complaining.

When the chief saw Liu Yin and his entourage coming quickly, he immediately stopped at the road and said sternly: "Chen Cang Road is forbidden to pass, please go back!" ”

Fortunately, when Zhang Le left, he left a few people from the Lieutenant's Mansion to help defend Taniguchi, and immediately someone said to Nashi: "You are too bold, this is my family lieutenant Youcheng." ”

Nashi's long face suddenly turned white, and he hurriedly bowed down and saluted: "The villain deserves to die, I don't know that the right master is driving, and he is begging for forgiveness." ”

Liu Yin didn't care, although this chief has a low rank, but from his appearance of enforcing the law, he is not a good soldier, Liu Yin said with some joy: "You did a good job." Where is Zhang Duwei? ”

Seeing that Liu Yin did not blame him, Nashi Chang was secretly happy in his heart, and when he heard Liu Yin's question, he immediately pointed to the cliff on the right and said: "The spies of the Wei State escaped from there, and Zhang Duwei has already led people to chase after him." ”

Liu Yin looked at the cliff, it was at least five or six zhang high, almost straight, without professional training, without the help of tools, it was almost unimaginable to climb it with bare hands. Liu Yin had already heard the details of the errand officer, the Wei spy disguised as a woodcutter had already climbed this cliff in just a few breaths, even if Liu Yin, who was born as a special policeman, was faster, he might not be able to gain the upper hand.

Master! Someone who can have such skills must be a master!

There is a rope hanging from the edge of the cliff, which is obviously left by Zhang Le when he led people up, although Zhang Le and their skills are good, but if they really want to climb with their bare hands, it is extremely difficult to complete.

Liu Yin left Chen Shou at the Dujiaping checkpoint, and he took Ah Jian and a few skilled errand soldiers to follow along the mark left by Zhang Le.
