After throwing the Nine Yin True Scriptures to Xing'er, Li Dao continued his research on the formation technique manuals that Young Master Yue had lent him.

Li Dao discovered that he liked to pass down the Nine Yin True Scriptures to others. Actually, he knew quite a bit of martial arts. The Blue Lotus Sword Scripture could not be randomly taught. The other martial arts could only be divided into individual inner force skills. If it was a single move, then unlike the Nine Yin Scriptures, the inner force skills would be combined into one.

He began to study the formation technique again. In a flash, half a month had passed. Li Dao had finally finished reading the formation technique manual that Young Master Yue had lent him. At the same time, he had gained a certain level of understanding towards the formation technique.

Combined with the traces he saw in the four cities, he discovered that the array formation laid down by the old man at the border was based on the Eight Inner Hidden Gates.

However, the old man at the border didn't simply arrange the Eight Inner Hidden Gates, he reversed them.

Hugh, Life, Wound, Du, Scene, Death, Shock, Open.

These eight techniques had been disrupted by the borderline old man, thus they were divided into eight hardships.

The Frontier Elder used the tragedy that occurred between the four families of Ouyang, Shangguan Yan, Huangfu, and Sima as the starting point. Afterwards, he provoked the entire Four Great Cities to gather the resentments of the citizens, hoping to refine the yin and yang energies of life and death.

Li Dao was not clear on the exact steps of the Fringe Elder in setting up the formation and breaking through the formation, unless he advanced into a martial arts grandmaster.

According to the ancient records, yin and yang energy could be refined from life itself and used to refine the elixir of life. Xu Fu had used Yin and Yang when he refined the elixir of immortality for Qin Shihuang.

What was the purpose of the old man refining the Yin and Yang Qi?

One must know that the Yin and Yang Qi of life and death was only a medicinal ingredient for the elixir of life. As for the rest, could it be that the old people at the border have all gathered them?

Li Dao did not believe that the Fringe Elder would be able to gather all of the spiritual medicines. Xu Fu still had to go to the East China Sea to look for the herbs.

Besides, Xu Fu had not successfully refined anything. Did the borderline old man think that he would succeed?

No matter how he thought about it, Li Dao still could not figure out the purpose of the old man at the border. Perhaps the life and death yin and yang energy were not only used to refine medicine.

Asking the old man at the border now was definitely unrealistic, so he would only know the answer after he succeeded. Before the Fringe Elder succeeded, he must become a martial arts grandmaster. At that time, he would go pick peaches and directly seize the fortune of the Fringe Elder.

Li Dao decided to leave Four Corners City first and go to another place to look for opportunities. His first destination was the Evil Buddha Sect mentioned by Half a day's time. As long as he was able to become a Martial Arts Grandmaster before the old man at the border succeeded, he would be willing to be his concubine.

The old man's schemes were definitely not small, and Li Dao became more interested in his plans.

Having thought through all of this, Li Dao felt much better. He stretched his back and prepared to go out for a walk. After all, it had been more than ten days since he had last seen the sun.

Pushing the door open, the fresh air blew into his face, the sunlight was especially dazzling.

However, Li Dao only furrowed his brows because Young Master Yue was kneeling in front of his door. His hair was messy like a chicken's nest and his beard was a mess. He no longer had the demeanor of a noble young master from before.

Young Master Yue raised his head when he saw Li Dao leave the room, his eyes filled with anticipation.

Li Dao immediately understood why Young Master Yue was acting in such a manner. He asked Xing'er, "How long has he been kneeling here?"

"He has been kneeling for seven days," answered Xing'er.

"Brother Yue, I promised a person that I wouldn't interfere with the grudge between your Sima family and Half Moon, so I won't deal with it for half a month. You should get up." Although he was moved by Young Master Yue's perseverance, Li Dao was still thinking of how he should get rid of the old man's peaches.
