Just two Hui Qi Dan pills are not enough to fill the dantian Xiaoding. Li Cong didn't ask Li Feng for another Qi Dan, but excused himself to be hungry and ate some wine and food.

Whether it was the dishes or the wine that fell into Li Cong's belly, they all turned into a rolling aura and merged into the dantian Xiaoding.

After eating a few bites of wine and food, Li Cong's mind suddenly moved, and he had thoughts while eating. Li Cong wanted to try it, and now his mental strength has improved much.

When the thought was born, a small tripod appeared in Li Cong's mind. The whole process of the rolling aura falling into Xiao Ding was also clearly seen by Li Cong.

This is the first time Li Cong has witnessed the scene of the aura entering the tripod, and involuntarily, Li Cong's thoughts followed the rolling aura into the tripod.

In a trance, Li Cong seemed to see that there were undulating mountains in the small ding. The rolling aura fell into it, reflecting those mountains and peaks like a fairyland.

But when Li Cong wanted to concentrate on watching carefully, those undulating mountains disappeared again, as if what Li Cong saw just now was just an illusion.

Li Cong knew that it was not an illusion, it was just that his thoughts were not strong enough.

Thinking back to what he saw and heard in a trance just now, Li Cong secretly thought: "That day, I thought that a mist rose in the mountains, was it because of these aura?"

Li Cong became more and more convinced that there was no problem with his speculation!

When Li Cong didn't know, just when he was thinking about Xiao Ding and thinking about it, on the top of the stone cliff, Hu Yifan suddenly raised his head.

"Hey, how did I feel Mr. Li's breath?" Hu Yifan cried out in surprise.

"Where?where??, where is Mr. Li?" The fox, who had been basking in the sun on the stone cliff, jumped up with excitement and looked around. But she didn't see anything.

Just when Hu Yichen wanted to use immortal magic methods to explore farther places, Li Cong just accepted his thoughts.

Li Cong is full and can start practicing again.

Hu Yifan shook his head in surprise: "Hmm, the breath is gone again." Is it really old and feels wrong again?"

Fox Yichen was furious: "Old man, you fool me?!"

"No, no, no. Hu Yifan was startled, and quickly waved his hand again and again, and explained weakly, "I was talking to myself just now, and I didn't talk to you." ”

"Do you dare to quibble? You said so loudly, obviously you just wanted to fool me!" Hu Yichen was even more angry, only to see her hands on her hips and scream, "Sisters, come out to help me beat people!"

"Great!"

Suddenly, a group of warblers and swallows came out. On the stone cliff, it was dusty and demonic......

......

Because of Li Feng, the best sparring partner, Li Cong's perception grew rapidly.

And because there is good food and drink every day, the dantian Xiaoding can be quickly filled when it is empty, Li Cong rarely pauses to rest from morning to night, and has been cultivating hard.

The rapid growth of martial arts comprehension, coupled with the non-stop diligent cultivation and hard practice, made Li Cong's cultivation potential burst out. Just ten days later, Li Cong's strength skyrocketed, and he successfully advanced to the peak realm of refining membranes!

Li Feng couldn't help but be dumbfounded, in the thousand-year history of the Li family, no one had ever had such a cultivation speed.

However, Li Feng didn't find it strange at all. In Li Feng's opinion, since the young master has the potential to ascend the Qiankun potential list, such a cultivation speed is very normal.

"It is rumored that the number one master on the Qiankun potential list has no worries, and it only took ten days to advance from the bone refining realm to the dirty refining realm. Although the young master is a little worse than him, he is proud enough! On the Qiankun potential list, there must be a place for the young master!"

"Ten days to get a great realm?" Li Cong's eyes flashed, "It looks like I have to work harder!"

The Qiankun potential list is just a list of martial arts powerhouses. For immortal cultivators, martial arts powerhouses are a fart!

I can think of it with my toes, among those strong people who are qualified to cultivate immortal enlightenment, there must be a large number of fierce existences, and the cultivation speed is several times faster than that of Xingwuwu. I can't even compare to the punishment without worry, even if I get that immortal token, how can I guarantee that the Yuyuan Immortal Sect will definitely accept me?

So, for the sake of the future, Li Cong continued to cultivate desperately as if he was crazy. If it continued like this, even Li Feng, a master of the Dirty Refining Realm, couldn't bear it, and was frightened by Li Cong's madness.

"Young master, let's rest. is the so-called way of civil and military, one by one. If you continue to cultivate like this for a long time, it will be harmful to the young master's body!" Li Feng said bitterly and tried hard to persuade him.

At first, Li Cong didn't want to stop. Where can I find such a good sparring partner? When I escape from the Li family, I am afraid that I will not be able to find such a good sparring partner for a long time.

However, after a day, Li Cong still stopped cultivating.

Li Cong also has to find the secret room of the study and steal the fairy token. This kind of cultivation can't go on forever, if Li Hengyi finishes the arrangement and returns to the Li family, he will never steal the opportunity again.

Therefore, in the face of Li Feng's continuous persuasion, Li Cong nodded reluctantly: "Okay, pause for a day." I've worked hard for you these days, you go to rest, and come here tomorrow to practice with me!"

Where did Li Feng know Li Cong's plan, he nodded and left.

When Li Feng walked away, Li Cong did not return to the study immediately, but walked around the outside and silently studied the surrounding terrain. After choosing an escape route, Li Congfang returned to the study.

Li Cong is not clueless, more than ten days ago, Li Cong already had a guess. As soon as he returned to his study, he walked to the suspicious spots, knocking here and there. After tapping several places in a row, a faint smile appeared on Li Cong's face.

"Here!"

Even hidden chambers will have echoes, and by tapping the echoes, you can determine the approximate location of the chambers.

Of course, the echo must be faint. Even if ordinary people keep tapping like Li Cong, it is difficult to hear these echoes. Not to mention, if the strike is not in the right place, the echo is almost non-existent, let alone audible.

Li Cong has the advantage of Li Cong, in his previous life, Li Cong was an excellent archaeologist, and it was the basic skill he had learned long ago to percussion and listen to the sound and identify the situation of the underground tombs.

Finding the location of the secret room is only the first step. It is also necessary to find the entrance to the secret room, and how to open it.

"Hopefully, it's easier to open the door. ”

Li Cong prayed to himself, slowly groping on the wall. It took about ten minutes for Li Cong to touch a movable wall brick.

"Is it okay to push it in?" pressed his right hand on the wall tiles, Li Cong was very puzzled. This is also a little too simple, not like Li Hengyi's handwriting.

Li Cong let go of his hand and tapped around again. It took about another ten minutes for Li Cong to touch another moving wall brick.

Continuing to explore like this, Li Cong found another movable wall brick. In this way, Li Cong found six movable wall bricks one after another.

"I see. Now, Li Cong has finally determined the method of opening, "You need to quickly press these wall tiles to successfully open the door of the secret room." Whether it's pressing too fast or too slowly, or pressing the wall tiles in the wrong order, there will be serious consequences!"

Li Cong's brows furrowed slightly, don't look at the design of this mechanism is very simple, but it is very troublesome to crack.

The six wall tiles are arranged and combined, and there are as many as 720 kinds of sequences!

It is impossible to guess the speed of pressing the wall tiles, and if the speed of pressing each wall tile is different, it will be an impossible task!

"If you really can't do it, you can only gamble. The hope of betting right is very small, and you can only resign yourself to fate!"

With one hand pressed on a movable wall brick, Li Cong struggled to think of a solution. Time waits for no one, and if he really can't think of a way to deal with it, he can only take a risk and gamble.

Li Cong thought about it for a long time, and he didn't know how much time had passed, and suddenly, Li Cong felt that the scene around him seemed to have changed.

Raising his head and looking around, Li Cong was taken aback.

"This ...... This is the world in Dingzhong!"

Surrounded by mountains and mist. The mountain breeze is slight, and the spring water is tinkling...... Isn't this the scene when I entered the world of Dingzhong?

Vaguely, Li Cong also heard the shouting voice of Hu Yifan, heard the shouting voice of Hu Yichen, and heard the shouting voice of many fox spirits!

Surprised, Li Cong wanted to run towards the place where the sound came from. But as soon as Li Cong took a step forward, the surrounding mist gradually faded away, and the surrounding mountains gradually disappeared. When he looked at it again, Li Cong suddenly found that he was back in the study!!
