Looking at Li Jiancheng who was smiling, Lu Chen turned around directly and left the Chongwen Pavilion, standing outside the Chongwen Pavilion, Lu Chen looked back at the Chongwen Pavilion again, and then left the imperial city with Liu Jing and the others who were waiting outside.

Out of the imperial city, Lu Chen went straight to Li Shimin's Tiance Mansion non-stop, Lu Chen obviously didn't have any idea of wanting to hide his itinerary, so he left the imperial city and came to the gate of Tiance Mansion with such a swagger.

"Oops! Isn't this Brother Lu Xian? Is this put out? When I came to the door of Tiance Mansion, I happened to see Cheng Yanjin walking out of Tiance Mansion, and when I saw Lu Chen, I immediately teased Lu Chen.

"Hmmm! It can be regarded as a release from prison! Lu Chen nodded directly at Cheng Yanjin and smiled, "Su Guogong is preparing to go home?" ”

"Something! Go to the barracks! Cheng Yanjin smiled at Lu Chen, "Don't go in yet!" Look at the hammer! Cheng Yanjin glared directly at the Yan people on the side, and the Yan people hurriedly entered the door to report, "I don't have any eyesight!" Does Lu County still need to hand over the name post when he comes here? Cheng Yanjin directly scolded the other slenders, and these all shrank their necks and lowered their heads.

"Su Guogong, what's wrong with you?" Seeing Cheng Biting Jin's angry appearance, Lu Chen asked in some surprise.

"It's not a matter of the court today!" Cheng Yanjin came to Lu Chen and said with an unhappy face.

"What's wrong?" Lu Chen looked at Cheng Yanjin and asked with some curiosity.

"A letter was sent from Lingzhou, saying that Jieli Khan's order to subordinate the general Gelun, on the orders of Jieli Khan, led 20,000 cavalry south, and had arrived near Shuozhou, the capital of Liang Division!" Cheng Yanjin didn't feel that there was anything to hide, and said directly to Lu Chen in a low voice.

"So, King Ren Cheng set off to return to Lingzhou?" Lu Chen looked at Cheng Yanjin and asked with a slight frown.

"Three days ago, King Ren Cheng had already set off to return to Lingzhou! After all, the only way for the Turks to go south is Lingzhou, and I am afraid that this time the Turks are going south, not as simple as 'fighting the grass valley'! Cheng Biting Jin and Lu Chen continued to analyze in a low voice.

"I'm afraid I want to take down Xicheng Pass too!" Lu Chen touched his chin and pondered, the Yanmen Pass in this era is divided into the West Pass and the East Pass, and the Yanmen Pass seen by later generations is actually the East Yanmen Pass established by the Ming Dynasty by abolishing the West and establishing the East, in fact, the real Yanmen Pass is the West Pass of this era.

Xicheng Pass, also known as the Iron Wrapped Gate, this West Gate is carved out on two mountains containing iron ore, this road is 36 zhang long (about 120 meters), the lower width is one zhang (about three meters), the upper width is six zhang (about 20 meters), because it is chiseled out on the mountain rich in iron ore, and it is the national gate guarding the north of the Tang Dynasty, so it is called the "Iron Country Gate", but after it is called Shunkou, because it is between two iron mines, it is called "Iron Wrapped Gate", and here is the real "Yanmen Pass".

Xicheng Pass is the first pass to defend the Turks to the south, and this place is easy to defend and difficult to attack, it is adjacent to Shuozhou, the capital of the Liang Division, this time Jieli Khan ordered his general Columne to lead 20,000 cavalry to come, I am afraid that he wants to take the opportunity to attack this Xicheng Pass, if they can occupy the Xishan Pass, then the Tang Dynasty can really "advance and retreat freely" and "take what you want".

Lu Chen's words naturally won Cheng Yanjin's approval, "At that time, in the court, the pharmacist also said this possibility, but those people from the family said that the pharmacist was worried about the sky, and the garrison of Xicheng Pass has always been impregnable, and it must not be lost!" And Your Majesty, you actually agreed with those people's statements! Cheng Yanjin said a little angrily, "Do those literati know how to fight better than us?" ”

Hearing Cheng Yanjin say that Li Yuan agreed with the words of those literati, Lu Chen was not surprised at all, because at this time, the 50,000 army of the Women's Army had begun to advance towards Xicheng Pass, even if Xicheng Pass was temporarily lost, Lu Chen believed that he had a way to take it back, and maybe even a "closed door and beat the dog"!

"I'm afraid Your Majesty has his own plans!" Lu Chen could only comfort Cheng Biting Jin.

"Alas!" Cheng Yanjin could only sigh, just at this time, Li Chunfeng, who was dressed in a gray robe, walked out of the gate of Tiance Mansion and came straight to Lu Chen.

"I've seen Su Guogong! I've seen Lu Xiangong! Li Chunfeng directly snorted at the two, "Your Highness, please enter the mansion for a while!" At this time, Li Chunfeng was only in his twenties, and his appearance was quite young, and Lu Chen was still a serious person who could "look at" Li Chunfeng in person.

It is said that the eyebrows fly obliquely into the sideburns, Lu Chen always thought that there would be someone with such long eyebrows, the eyebrows have grown to the sideburns, how long the eyebrows are, and the eyebrows of "one eyebrow are long" did not say that they flew obliquely into the sideburns!

However, after seeing Li Chunfeng, Lu Chen believed this sentence, this guy's two eyebrows really flew obliquely into the sideburns, and a pair of eyes are also, which can be described as "narrow" eyes, as far as Lu Chen knows, there are only two kinds, one is called Danfeng eyes, and the other is called willow leaf eyes, but Li Chunfeng is not these two, but a very special kind, the eyes are very normal, that is, the corners of the eyes are long, Lu Chen even doubts, if the corners of this guy's eyes are a little longer, can he cut his face!

As for the fingers, they are really "slender", Lu Chen feels that his fingers are not short, but compared to Li Chunfeng's fingers, they seem to be a little shorter.

Li Chunfeng gave Lu Chen the feeling of "slender", even if Li Chunfeng was wearing a Taoist robe, Lu Chen still felt that this person was very "slender".

"Then Su Guogong, let's say goodbye?" Lu Chen nodded at Li Chunfeng, then looked at Cheng Yanjin and arched his hand.

"Hmm!" Cheng Yanjin also nodded, arched his hand at Lu Chen, walked quickly to his mount, turned over on the horse, and rode away with the escort, and after seeing Cheng Yanjin leave, Lu Chen turned his head to look at Li Chunfeng again.

"Grandpa, please!" Li Chunfeng made a "please" gesture at Lu Chen.

"There is Daoist Lao Li!" Lu Chen said with a smile and walked up the steps of Tiance Mansion, "Has Li Daozong been in contact with Yuan Daochang recently?" Following Li Chunfeng's side, Lu Chen asked with a smile.

"I haven't seen Brother Yuan Dao recently!" Li Chunfeng shook his head slightly and replied.

"My father has always been very curious about Yuan Daochang's physiognomy, and according to rumors, Li Daochang is proficient in yin and yang techniques, I wonder if this prince has a chance to let Li Daochang take a lesson for this father?" Lu Chen was beside Li Chunfeng unhurriedly, as if he was admiring the scenery in the Tiance Mansion, and asked casually.

"This..."Hearing Lu Chen's words, Li Chunfeng hesitated, "It's fate!" Li Chunfeng responded with a smile.
