When the scripture hall came out, Yu Shixing told Yu Zhongtian what he had seen and heard, and then chose to close the door, because ten days later was the night of the full moon, and he had to refine the "Spiritual Fire Pass" before that, so as to have more confidence to go to the Sea of Flames!

"Whew!"

A flame churned and jumped in Yu Shixing's palm, the burning flame slowly became smaller under the control of weak spiritual power, and the essence of the flame was all compressed into a burning spiritual power firestream, all he had to do was to remove the impurities from this spiritual power fire, elevate it to the purest spiritual power, and merge into the Danhai!

Yu Shixing's whole body was steaming with heat, his skin became red from the scorching flames, and beads of sweat the size of beans oozed from his forehead! This use of flames to cultivate is really not something that ordinary people can bear, not to mention that the spiritual power condensed in his body is extremely thin, so it is particularly difficult!

However, no matter how hard he tried, he had no intention of giving up, he let out a long breath, and once again forced out the spiritual power of his whole body, and the spiritual power surrounded the flames, constantly refining, the flames became smaller and smaller, but they also became more and more refined!

Finally, under the guidance of "Spiritual Fire", he skillfully used spiritual power to control the flames, and a layer of spiritual power covered the flames, imprisoning its heat and burning. The flame spiritual power entered the palm of his hand, and he walked cautiously along the meridians, even if there was a layer of spiritual power that enveloped the scorching heat, it still made him feel the pain in his heart, and many of the meridians were trembling, but even so, he had no intention of retreating, and still chose to cultivate without hesitation!

After an hour and a lot of effort, Yu Shixing finally subdued the spiritual power flame, dragged it into the Danhai along the meridians, and melted into the inner Dan suspended in the Danhai, with a trace of fiery red lines on the crystal clear beads!

This means that a trace of flame spiritual power has been subdued!

When he excitedly wanted to use this trace of flame spiritual power to dissolve a trace of Gu poison, he was instantly poured a basin of cold water! Because when the flame spiritual power had just reached the range of Gu poison, he actually became trembling, and he didn't dare to approach at all!

Yu Shixing looked at the meridians inwardly, and naturally saw everything clearly, and before the flame spiritual power could pay attention, he forcibly used the power of the Danhai to crash it into the Gu poison, and the fiery spiritual power disappeared without a trace as soon as it came into contact with the Gu poison!

Its spirituality is too low to work on Gu poison!

The Gu poison that had absorbed the spiritual power of the flames seemed to have awakened, and it suddenly blocked a meridian in Yu Shixing's left chest, greedily absorbing the spiritual power he had just condensed and gathered!

Yu Shixing slowly opened his eyes, looking tired, although he didn't dissolve a trace of Gu poison, but he also mastered the essentials of the first layer of the "Flexible Pass", and he had a little confidence in going to the Sea of Flames!

Ten days passed in a flash, and in the evening of this day, Yu Shixing said goodbye to his parents and embarked on the road alone to find the entrance to the Flame Sea! Although Yu Zhongtian was reluctant, he had to reluctantly agree to the only way to crack his son's Gu poison! Fortunately, in the Hall of Scripture, the generous funding of Yu Ke's ancestors made him feel a little relieved!

Yu Shixing rode the dark cloud cone and marched towards the 100,000 mountains in the south of the Yu family! The Qiankun mirror in his hand was constantly searching for information about the Sea of Flames!

The Sea of Flames is a legendary place, although there are many entrances in this world, but no one knows its specific location, the real one is hard to find!

The night was deep, and the dark cloud cone took Yu Shixing to run millions of miles under the moon, crossing countless mountains and rivers, but still couldn't find the entrance. On the mirror, the white bright spots are erratic, indicating that the entrance is moving over time, and only when the moon is full, the position of the entrance will be fixed for a quarter of an hour!

"Whew!"

A purple gas streaked across the sky, the moon began to slowly round, and the Qiankun mirror showed that there was a bright spot in a valley of the 100,000 Great Mountains that was flickering steadily!

"Found it!
