章 638: The Fourth Change in the Fish-dragon Realm

Zhang Ruochen held Sword One once again and read it like crazy. He perceived it while nodding. Each character sprang to his mind like a sword.

Over the next few days, he still practiced the Scripture of Emperor Ming's Empyrean for six hours as before, but he spent the rest of the time practicing Sword One.

Three months later, he practiced to the fourth level of Sword One after successive breakthroughs.

Even Cyan-robed Emissary at the Seventh Change in the Fish-dragon Realm could only practice to the fourth level. However, it had taken her 10 times longer than Zhang Ruochen.

He had secluded himself for refining in the Scroll World for half a year. He completely solidified his cultivation and his Genuine Qi became very pure. His cultivation reached the acme.

"Now, I have at least a 70% chance of success to open up the first holy meridian."
