Time is spent in Zhou Yifeng's cultivation, day by day.

Two months later, under the accumulation of spirit stones that Zhou Yifeng had no regard for the cost, he finally stepped into the tenth layer of qi refining. At the same time as the strength increased again, there were also major changes in the dantian, in the ninth layer, it was all transformed into a liquid true element, and it gradually became viscous, faintly solidifying!

When he stepped into the tenth floor of the foundation building, Koku told him that this stage was the most important stage and would determine the quality of Jindan.

The monk's golden pill, like the realm, is also divided into nine grades, with the lowest of the nine grades and the highest of the first grade.

As far as Zhou Yifeng was concerned, the middle and lower grades were not within the scope of his consideration, and his goal was the upper third-grade Jindan, or the first-grade Jindan! Xiaokong had told him that the Jindan was the first step into the high-level cultivators, and the quality of the Jindan would directly affect his future achievements! For example, the high-level leaders of the Qi Yun Sect, including Mo Qingyun, if there were no accidents, maybe in this life, they would not be able to cultivate to the True Realm!

As for the third-grade Jindan, but there is a chance to ascend to the immortal realm, especially the first-grade Jindan, as long as it does not die halfway, it will definitely reach the peak of the cultivation realm, and then step into the immortal realm through the ascension of the immortal tribulation! As for whether or not you can survive the ascension of the immortal tribulation, it depends on the individual's fate. Although the Immortal Ascension Tribulation is extremely dangerous, no matter what, at least there is a chance to contact a higher level.

However, all this is still far away from Zhou Yifeng, and at present, according to Xiaokong, he needs to consolidate for a period of time before he can try to impact the Jindan Realm, so as not to cause an unstable foundation.

It's just that there is no one here, and it is impossible to temper oneself by fighting.

After consideration, the small empty road:

"Young Master, it's better to do this, you now enter the Thunder Source Bead Space and use the power of thunder and lightning there to forge your body. First, the power of thunder and lightning can make the true yuan more condensed, and second, it can also take this opportunity to cultivate the Purple Thunder Refining Body Technique!

Zhou Yifeng's eyes lit up and said:

"Not bad, good idea!"

But then he came to his senses and asked in surprise:

"You mean, my current body can enter the Lei Yuan Pearl?"

In the past, Zhou Yifeng only entered with divine sense, and he had never entered Lei Yuanzhu in the flesh!

Xiao Lei nodded and said:

"Yes, young master!"

Zhou Yifeng was overjoyed, he didn't expect that after Xiao Lei regained consciousness, there would be such benefits!

"Will this make you fall into a weak state again because of the excessive energy consumption?"

He remembered that when he opened up the sea of knowledge, Xiao Lei almost exhausted all his energy in order to keep his sea of knowledge, causing the thunder in the thunder source bead to be exhausted.

Xiaokong smiled and said:

"Young master, rest assured, now that I have absorbed an origin of the Nine Sources Tower, although it is far from the heyday state, it is no longer so ignorant, and there will definitely be no such situation again!"

Zhou Yifeng was relieved at this time, and saw that Xu Wenmin was still refining and absorbing the 10,000-year-old stone stalactite, so his heart moved, only to feel that a suction force came, and his body went straight to Lei Yuanzhu, who had already escaped from the sea of knowledge.

When he opened his eyes again, he was already in the space inside the Lei Yuan Bead, and his eyes were densely packed with silver thunder.

After Zhou Yifeng stood still, Xiao Lei's figure slowly appeared in front of him, and then walked towards the exercise stone tablet together. The thunder on the road flashed like soldiers lined up to be reviewed, and a passage was more than a foot wide for them to pass through.

When he came to the stele, Zhou Yifeng sat cross-legged and said to Xiao Lei:

"Let's get started!"

Xiao Lei nodded, his figure flashed, and he disappeared into the Gongfa stele. Suddenly, the black thunder arc on the top of the original stone tablet jumped happily as if it had life! And the thunder arc in the entire Thunder Source Bead space also began to move regularly. In Zhou Yifeng's opinion, it is like a school of sardines in the sea, although it is dense, it will never collide!

"Young master, here it begins!"

With Xiao Lei's transmission, a small thunder arc fell straight down and smashed on the top of Zhou Yifeng's head!

Hearing Xiao Lei's voice, Zhou Yifeng's heart froze, and the Purple Thunder Body Refining Technique was quietly running!

When that thunder arc fell, Zhou Yifeng only felt a sharp pain coming from the top of his head, and his eyes were dark, and the purple thunder refining technique was almost interrupted!

But then, a slightly itchy sensation spread throughout his body, making him moan softly, not caring at all about the burnt smell coming from the top of his head, and said:

"Come again!"

This thunder arc, coupled with the running Purple Thunder Refining Body Technique, made him feel faintly showing signs of breaking through the second layer of the spirit body!

Under the great joy, he even ran the purple thunder refining technique with all his might, allowing the thunder arcs to fall!

And the entire Lei Yuanzhu is completely in the hands of Xiao Lei, and Xiao Lei and Zhou Yifeng are in close proximity, of course he knows Zhou Yifeng's current state, and accurately controls the interval between the thunder falls.

As the thunder arc fell, Zhou Yifeng could feel that his skin was slowly transforming, and silver spots kept emerging, moving towards the second layer of the thunder spirit body.

An hour later, another thunder arc fell and was absorbed and refined by Zhou Yifeng, and the skin of the whole body flashed with silver light, and a powerful momentum spread, and it was done!

The second layer of the thunder spirit body!

Feeling the strength of his flesh that had become stronger, Zhou Yifeng couldn't help but feel a surprise in his heart, the Purple Thunder Body Refining Technique was really extraordinary! Just the second layer of the spirit body made his physical strength nearly fifty percent stronger! If he cultivated to the peak of the spirit body, it would definitely increase several times! At that time, with the strength of the flesh alone, coupled with the defensive power comparable to the best spirit weapon, he would be invincible when he encountered an opponent of the same level!

After a little pranayama for a while, a new round of refining mode began!

At this time, Zhou Yifeng, due to his promotion to the second layer of the spirit body, the power of his body to absorb thunder and lightning was significantly accelerated, from the original interval of thirty breaths, directly adjusted to fifteen breaths!

Seven days later, the spirit body is on the third floor!

A month later, the spirit body is on the fourth floor!

That's why it's like this, it's because the fourth layer of the spirit body has entered the middle stage of the thunder spirit body, and it consumes more thunder and lightning power, and there is a qualitative leap!

Two months later, the fifth layer of the spirit body!

Then, after another month of cultivation, the peak of the fifth layer had already been reached, but the opportunity to break through the sixth layer had not yet come, Zhou Yifeng knew that this had reached a bottleneck! After all, he was only cultivating at the tenth layer of the foundation now, perhaps, the sixth layer of the thunder spirit body, he needed Jin Dan to cultivate!

And after these three months of body refining, he also felt that the power of thunder and lightning not only changed his physical body, but also made his true yuan more condensed, and steadily reached the peak of the early stage of the tenth layer of foundation building!

Of course, the biggest harvest is the flesh.

The physical body at the peak of the fifth layer of the Thunder Spirit Body, its strength was actually twice as strong as when it was at the second layer! Now, as long as he ran the Purple Thunder Refining Body Technique, golden points of light faintly flashed all over his body, and his defensive power soared extremely quickly. And when these points of light are all connected, it will be the realm of the sixth layer of the Thunder Spirit Body!

Greeting Xiao Lei, the two flashed out of Lei Yuanzhu and stood on top of the World Mountain.

For three months, the World Mountain has not changed at all, and it is still silent and quiet. And Xu Wenmin and Xiaokong, who were not far away, showed no signs of waking up.

After glancing at it, Zhou Yifeng sat cross-legged, and after the spirit stone and spirit gathering array were prepared, the Tianyan Thunder Technique suddenly activated in his body, impacting the peak of the tenth layer of the foundation, and it began!
