“If I can advance to the ninth rank, I will definitely purge the parasites within the Ye Family Fortress. So what if it means a complete break with the Yun Family Fortress?” Henry York thought of Matthew York, his heart turning cold.

“Looking back, the Thunder Roar Inner Strength technique is indeed very incomplete. There are thirteen errors and omissions in just the first level. I’ll explain them to you one by one. This will surely help you in cultivating the first level of the Thunder Emperor Technique.” Henry York patiently explained to Charles York the various mistakes in cultivating the Thunder Roar Inner Strength.

Are there really only thirteen errors in the first level of Thunder Roar Inner Strength? Why have I found thirty-five? Could I be wrong? After all, Father is a peak eighth-rank expert, and his understanding of cultivation methods far surpasses mine. Charles York frowned slightly.

“Chen’er, what’s wrong? Is there something you don’t understand?” Henry York noticed that Charles York’s expression was a bit off.

“I was just concentrating and thinking,” Charles York quickly replied.

“You are exceptionally talented. If you can comprehend this, it will greatly benefit your cultivation. You could break through to the fifth rank within a month, and the sixth within a year.”

The thirteen errors that Henry York mentioned, Charles York had already discovered. But what about the remaining twenty-two? How should he interpret those?

“Father, in the last line of the first level of Thunder Roar Inner Strength, ‘directly reach Tianchong, as if leaving the Divine Gate’—is there really no problem with that?” Charles York asked cautiously.

“Of course there’s nothing wrong with it,” Henry York thought for a moment and replied.

Could it really be that I’m wrong? Charles York was a bit confused, yet he felt he wasn’t mistaken. Still, he was somewhat uncertain and didn’t dare voice his doubts.

“I’ll go back and think it over carefully.”

“Once you’re back, be sure to train diligently. Do not slack off! The competition for the position of family head is no trivial matter,” Henry York said solemnly.

“Yes,” Charles York replied earnestly.

After returning from his father, Charles York still felt some unresolved confusion in his heart. Why were those errors so obvious, yet his father hadn’t noticed them? Could it be that his own understanding of cultivation methods was flawed?

He really couldn’t figure it out. His own understanding was already set and couldn’t be changed, so he could only continue cultivating.

He practiced the Thunder Emperor Technique for several hours, then reviewed the family’s basic martial arts techniques. After a while, he took out the Yuan Thunder Body martial technique.

The Yuan Thunder Body technique was created based on the Thunder Roar Inner Strength. It was the most domineering and powerful among the Ye family’s many martial arts, invented by a brilliant ancestor. In battle, it could use Thunder Roar Inner Strength to transform into a Thunder Body, causing one’s strength to soar severalfold. Although Father’s strength was only at the eighth rank, with this Yuan Thunder Body technique, even some ninth-rank experts didn’t dare underestimate him.

Back then, Henry York spent a full three years cultivating this Yuan Thunder Body technique, and at that time his profound energy had already reached the seventh rank, giving him a solid foundation. Now, however, Charles York’s profound energy was only at the fourth rank. When Henry York passed the Yuan Thunder Body technique to Charles York, he didn’t expect Charles York to master it within seven days—he just wanted Charles York to take a look at it, in case he gained some insight.

“To actually be able to transform into a Thunder Body, making the flow of profound energy inside the body more than three times faster than usual—no wonder the ancestor who created the Yuan Thunder Body technique was so remarkable.” Charles York flipped through the various methods for circulating inner strength in the Yuan Thunder Body technique, seeming to gain some understanding.

The most crucial foundation for cultivating the Yuan Thunder Body was to greatly increase the speed at which profound energy circulated; otherwise, it would be impossible to sustain the energy consumption of the technique.

For ordinary people, increasing the speed of profound energy circulation was extremely difficult. But Charles York seemed to have an excellent advantage: as long as his mind touched the flying dagger, the profound energy within it would surge forth, circulating several times faster than normal!

“This technique is definitely worth practicing!” The Thunder Emperor Technique that Charles York cultivated was several levels higher than the Thunder Roar Inner Strength, so activating the Yuan Thunder Body was no problem at all.

After memorizing all the methods of the Yuan Thunder Body, Charles York used his mind to activate the flying dagger and circulate his profound energy. Suddenly, he felt a surge of powerful, pure profound energy rushing out, flowing through all his meridians. He gave a low shout, “Yuan Thunder Body!”

He felt his entire aura suddenly soar several times over, his whole body taking on a metallic silvery sheen, and a powerful thunder force filled his body, as if it could burst out at any moment.

After only three seconds of circulation, Charles York felt his strength failing, his dantian’s profound energy completely depleted. His face turned pale, and he quickly stopped, bracing himself on the table and gasping for breath.

This Yuan Thunder Body was truly domineering. If he used other martial techniques while activating it, their power would be multiplied several times!

However, with Charles York’s current level of profound energy, using the Yuan Thunder Body was really too much of a strain—he could only maintain it for three seconds at most.

Even if it was only three seconds, it was enough to make Charles York extremely excited. After all, when his father was at the seventh rank, it took him three whole years to master the Yuan Thunder Body!

“If I want to use the Yuan Thunder Body in actual combat, I must be able to maintain it for several more seconds!” Charles York thought. Three seconds was indeed too short. Although the profound energy in the flying dagger was inexhaustible, the profound energy needed to activate the Yuan Thunder Body had to pass through the dantian. Without the flying dagger’s supply, with Charles York’s fourth-rank strength, he simply couldn’t use the Yuan Thunder Body.

Charles York’s body still couldn’t adapt to the massive consumption of the Yuan Thunder Body!
