Wu You would spend part of her time on discovering and training. During this time, Wu Yu started setting up the Million Swords Formation with the materials he had prepared in advance. 

The Million Swords Formation was the highest tier Heaven and Earth Spirit Design that Wu Yu could create at this moment. On typical days, one wouldn't be able to see any signs of the spirit design. However, once it was activated, there would indeed be a million sword qi hovering. Ordinary people wouldn't be able to get in at all. 

The Million Swords Formation wasn't just a minor upgrade from the previous 10,000 Swords Formation that had protected the Heavenly Sword Sect. 

This was the first time Wu Yu had put the Million Swords Formation into reality. 

He had long prepared the materials, precious treasures, and immortal essences. In addition, he had practiced drawing the spirit design of the Million Swords Formation previously. Therefore, he was familiar with the whole process. Although it was his first time setting it up, he still completed the Million Swords Formation within the estimated time under his precise and accurate control. 

Once activated, Capital Wu would be protected within the Million Swords Formation. 

A month had passed. 

The Million Swords Formation was completed...
