After a long time, Dao Wuji came back to his senses and muttered to himself, "Could it be ...... He's going to build a double foundation!"

Dao Wuji himself was taken aback by his own speculation, "Impossible! Absolutely impossible! How rare is it to build a double foundation? With his qualifications, it is absolutely impossible!"

In fact, this is not complaining that Wuji does not believe it, only because of the countless Tianjiao generations in the Qingtian Continent for tens of thousands of years that there will be a person who has built a double foundation, and the double foundation building must not only be talented, but also have the opportunity to go against the sky!

The people who build the double foundation are all amazing talents, enough to become a generation of grandmasters who created their own school!

What's more, there is also a synonym for double foundation, that is, invincibility at the same level. The pen "Fun" Pavilion www.biquge.info but where there is a double foundation, two cyclones in the foundation period, two Jindan in the Dan period, and two Yuan babies in the Yuan infant period. This makes its burst of combat power at least double, so how can others fight?

Therefore, since ancient times, every monk who has built a double foundation has been extremely powerful!

But in an instant, Dao Wuji closed his mouth, and the boss with his eyes open, couldn't say a word, because he already knew that Wang Xuan really planned to build a double foundation!

And if he knew that Liu Yiyi, who he personally sent out of Qingyun Tomb, was also a double foundation not long ago, it is estimated that his jaw would fall in shock.

Dao Wuji stopped thinking about it, and looked at Wang Xuan with a sneer, only to see Wang Xuan shouting in a low voice: "Thunder Dragon, come out, it's up to you!"

Wang Xuan's thunder dragon in the sea seemed to be able to understand Wang Xuan's words, and he raised his head and let out a shocking dragon roar, rushing out!

After circling around Wang Xuan for a few times, the thunder dragon entered Wang Xuan's body again, constantly wandering in various meridians.

As the thunder dragon continued to swim away, the spiritual power that Wang Xuan had just absorbed in his body also flashed with purple lightning, and gradually transformed into a thunder attribute.

When Dao Wuji saw the thunder dragon appear, he finally understood, and looked at Wang Xuan in disbelief, but he didn't react for a while.

He ...... He wants to use the thunder dragon to transform spiritual power into thunder attributes, and use thunder to build a double foundation! How is it possible? The power of heavenly thunder is not even daring for me to control, how can a mortal like him control it...... No, not even touching! Such audacity will be damned!"

In the disbelief of Dao Wuji, the spiritual power of the twenty spirit stones beside Wang Xuan was exhausted, and they turned into powder and fell.

Wang Xuan waved his hand again without any pause, and another twenty spirit stones were suspended around his body.

Wang Xuan's mind moved, and the huge spiritual power contained in the top-grade spirit stone quickly poured into Wang Xuan's body, and then it was transformed into thunder attribute spiritual power while the thunder dragon was wandering.

In the blink of an eye, two more hours passed, and Wang Xuan absorbed nearly a hundred top-grade spirit stones, and at this moment, the spiritual power he absorbed was already several times that of when Liu Yiyi built the foundation.

The reason why Wang Xuan consumes so many spirit stones is because Wang Xuan's dantian is much larger than Liu Yiyi's, and secondly because Wang Xuan's spiritual power is more condensed than Liu Yiyi's.

Seeing that the spirit stones around Wang Xuan were decreasing, Dao Wuji saw it in his eyes and felt pain in his heart.

"Those spirit stones were originally mine!

Dao Wuji wanted to rush out several times, but he couldn't hold back when he saw the preserved eggs. Although Pi Dan didn't recognize him, thinking of its previous horror, and his current cultivation had not yet recovered, Dao Wuji really didn't have the courage to face Pi Dan, so he had to stare at Wang Xuan hatefully, cursing constantly in his heart.

"Wasting so many top-grade spirit stones of the deity, why haven't you survived yet! If you die, you are lucky, and when the deity makes a move, it will definitely make you worse than dead!"

......

Finally, after absorbing more than a hundred top-grade spirit stones, Wang Xuan stopped and no longer absorbed spiritual power.

At this moment, the spiritual power in Wang Xuan's body had reached a very terrifying level, Wang Xuan was calm, carefully controlling the thunder dragon, and transforming the spiritual power absorbed in his body into thunder attribute little by little.

Three hours passed, and eighty percent of the huge spiritual power that Wang Xuan had just absorbed in his body had finally reached a bottleneck after being converted into a thunder attribute, and he could no longer be transformed.

This is because spiritual power is not completely pure after all, and the unrefined part cannot be converted into thunder attributes. Although Wang Xuan was not very satisfied, it was quite amazing to be able to reach eighty percent.

Wang Xuan also understood that he was too greedy, smiled self-deprecatingly, and no longer tried to transform, but continued to compress and condense the thunder attribute spiritual power until the thunder attribute spiritual power also turned into a liquid state, showing a faint purple color.

As soon as Wang Xuan's mind moved, two streams of spiritual power, one white and one purple, flowed along the meridians, and even the sound of rushing water could be heard. The two spiritual powers are distinct and do not interfere with each other, and even the white ordinary spiritual power seems to be a little afraid of the thunder attribute spiritual power.

After running like this for two weeks, Wang Xuan stopped.

At this moment, Wang Xuan's dantian was also clearly divided into two parts, one side was a white ordinary spiritual power vortex, and the other side was a light purple thunder attribute spiritual power.

The thunder attribute spiritual power was like a lilac sea, and from time to time there was a flash of lightning.

With a long sigh of relief, Wang Xuan opened his eyes, his eyes full of determination: "Finally, the second whirlpool is about to be formed, and this is the key to whether or not the foundation can be built twice......"

Thinking of this, Wang Xuan didn't hesitate, and his divine sense manipulated the lilac thunder attribute spiritual power slightly.

A sharp pain came, and Wang Xuan let out a muffled snort, but the spiritual power only moved slightly, like a breeze blowing across the water, and it disappeared again as soon as it rippled......

Wang Xuan gritted his teeth and once again manipulated the thunder attribute spiritual power to turn around, although it was only a slight movement, it was an unimaginable sharp pain coming.

Wang Xuan gritted his teeth and held on, his forehead was instantly covered with dense beads of sweat, but after all, it was a turn, and no matter how painful it was, it was worth it.

Wang Xuan endured the severe pain, and controlled the thunder attribute spiritual power to turn again, this time it turned a small half circle, but Wang Xuan, who was in pain, couldn't help but grin his teeth for a while.

Seeing it in his eyes, Dao Wuji couldn't help but feel a burst of joy, "Stinky boy, it's really beyond your strength! How can you be delusional about double foundation building? Now it's okay, it's better to hurt you to death!"

Wang Xuan's control of spiritual power without any pause turned again, and the sharp pain hit like a tide.

"Hiss......"

Wang Xuan was so painful that he almost fainted, but this time he finally turned around.

With just one turn, the following is simple.

Wang Xuan wiped the sweat from his forehead and controlled the thunder attribute spiritual power to rotate again.

One, two, three......

The thunder attribute spiritual power slowly turned, and it turned faster and faster, and after an hour, gradually, the prototype of a vortex was revealed.

Wang Xuan couldn't help but breathe a sigh of relief, but he didn't completely relax, he still carefully controlled the spiritual power to rotate continuously, and a complete vortex slowly appeared.

Finally, the thunder attribute spiritual power vortex finally appeared completely, and it rotated on its own, and a trace of electric light flowed above the lilac vortex, like a small thunder pool, which was very beautiful.

However, at this time, the vortex of ordinary spiritual power was stagnant, and it actually flashed to the side. It seems that he is very afraid of the thunder attribute spiritual power vortex, and he is unwilling to get too close.

Wang Xuan felt something unusual, and hurriedly checked it, and couldn't help but be surprised.

Because, the previous ordinary spiritual power vortex turned slower and slower, and when it was about to stop, the cold sweat on Wang Xuan's forehead came down in a flash, and he couldn't help but scold: "Nima, how can this be ......?"
