Originally, Lu Bei and the others almost didn't find out the identity of this person, but fortunately, the entourage of the Thirteenth Prince inadvertently mentioned it in a drunken chat, and then the bottom was revealed.

The founding emperor of Cai was an old minister of the last dynasty of the Great Song Dynasty more than 300 years ago, and after the death of Emperor Xiaowu of the Great Song Dynasty, he rose up and became the king of the land and created the territory of the Cai State.

Leng Mochen followed Emperor Cai to fight everywhere, made great contributions, and could have been crowned a prince, but this person was quite loyal to Emperor Cai, and after Emperor Cai's death, he volunteered to protect the imperial tomb with the strength of a clan, so the Leng family was also valued by Emperor Cai in previous dynasties, and was granted considerable privileges, and the most important thing is that the Leng family can freely enter and exit the royal book room and learn royal martial arts.

Leng Jishi is the head of the Leng family of this generation, cultivating the strongest royal martial arts, cultivating to the Seven Realms of Gundam Martial Arts, and his strength is by no means below the Void Valley.

In addition, the Leng Ji World also has four Leng Patriarch elder-level characters, all of whom are extraordinary, and their cultivation is above the Transformation Yuan Realm.

In addition to these heavyweights, the Thirteen Princes also have Imperial City spies and guards around them, although these people have never been on the battlefield, but they practice top martial arts, and they are extremely dangerous, and they are proficient in spying intelligence, assassination and sneak attacks, and frontal group attacks.

There were no Xianmen disciples behind the two forces, which made Fang Ling somewhat relieved, and at the same time, there was no trace of Taiyan Gongmen people around, everything seemed to indicate a good situation.

Whether it is Tsing Yi Fang or the Thirteen Princes, this time they have mobilized their hole cards. Tsing Yi Fang obviously also noticed the changes near Sanquan County, with Wei An's cleverness, it was impossible not to see the strangeness in it, the people of Qingping County have been standing still, it must be because the underground palace is about to open.

In fact, for the people of Tsing Yi Fang, the biggest problem is how to break through the main gate, the main part of the underground palace is made of a whole piece of basalt stone several zhang thick, and there is a top door stone weighing thousands of catties behind the door.

The top door stone is like a shackle on the door, pressing the giant gate, coupled with the thickness and weight of the giant gate, it is almost impossible to enter, and around the main gate, there are multicolored stones filled in the way of pouring, which is even more difficult to break.

However, Tianji Hou's subordinates have many capable people, and they have their own methods of breaking through the main gate and the top gate stone, so of course there is no need for Fang Ling to worry about this.

The Thirteen Princes' side did not have any action to infiltrate Qingping County, but Fang Ling knew in his heart that the cultivation had reached the level of the Leng Shi, and ordinary people would not be able to monitor them at all, and the purpose of the Thirteen Princes bringing the Leng family was also about to come out, since they were guarding the Imperial Tomb, they must be very familiar with the mausoleum organs and the like, maybe they would find other passages in the dark early, and they would wait for the people of Tianji Hou to enter the underground palace.

A few days later, the eyeliner of Qingping County finally came to the news, in the afternoon, the main gate of the underground palace was finally opened, and after getting the news, Fang Ling and the others rushed to the ghost mountain along the tunnel overnight.

The number of people in the Green Alliance who followed Fang Ling and the three of them was only fifty or sixty, and their cultivation was above the stable period of the Melting Qi Realm, except for the elder-level figures of the Green Alliance's chief rudder, they were the helmsmen of each rudder and the elite of the elite.
