Once the foundation was built, the entire sea of knowledge began to undergo earth-shaking changes. Knowing the sea in the river and the sea. Originally the size of a small lake, Zhihai continued to expand and eventually became a large lake.

It skyrocketed more than ten times compared to the beginning, and at this moment, Ou Haoyun found that his divine consciousness had also expanded more than ten times, and every grass and tree within a radius of dozens of miles was shrouded in his divine consciousness.

The biggest change is his Purple Mansion Dantian, at this time in his Purple Mansion Dantian, the true qi is constantly rolling, and the dantian is constantly being expanded, but the speed of the dantian is not comparable to the speed at which the true qi increases.

In the center of the dantian, centered on the location of the sword fetus, a vortex was formed, constantly absorbing the surrounding true qi, and then you could see that the true qi in the entire dantian was constantly compressed.

The aura from the outside world continued to flow into Ou Haoyun's body. The aura between heaven and earth is too thin. Ou Haoyun is an extraordinary cultivator, and when he breaks through, the movement is even greater.

The aura within a radius of ten miles surged towards Ou Haoyun frantically, and then was absorbed by Ou Haoyun. But the aura within ten miles couldn't satisfy Ou Haoyun at all.

Soon the aura of a hundred miles of radius continued to converge here, and when the aura of a hundred miles of radius was attracted by Ou Haoyun, a terrifying tornado storm formed, and from a place a hundred miles away, it frantically rammed towards the place where Ou Haoyun was.

And within a radius of 100 meters from Ou Haoyun, it is calm, in this calm space, the rich aura is almost visible to the naked eye, as the closer to Ou Haoyun, the greater the concentration of the aura, close to Ou Haoyun's side, the aura is almost to the point of liquid.

"Tick"

With a soft sound, I don't know when, a drop of liquid true yuan was formed in Ou Haoyun's dantian, and with the formation of this drop of liquid true yuan, the aura surged towards Ou Haoyun even more frantically.

The wind and clouds suddenly changed, the heaven and the earth changed color, and the entire heaven and earth were almost dark at this moment, and the aura within a radius of a hundred miles was instantly absorbed by Ou Haoyun, making the aura within a radius of a hundred miles form a vacuum.

Thick clouds began to form in the sky, and layers of black clouds were like dark clouds pressing on the top, more like thousands of troops and horses, and at this time, Ou Haoyun's breath of building a real person was becoming more and more obvious.

"Hey, the breakthrough failed."

Seeing that Ou Haoyun was about to break through to the foundation building period, the ancestor hurriedly withdrew his attack, but looking at the vision above the sky, he couldn't help but sigh.

At this time, it can be seen that there is a thundercloud condensation in the sky, but it is about to succeed in condensation. The thundercloud actually began to break up, and seeing that the ancestor here still didn't know what was going on.

Ou Haoyun's breakthrough failed.

Ou Haoyun's vision of breakthrough is almost comparable to the scene of Jindan's real breakthrough, and naturally requires a large amount of aura. It's a pity that this is the era of the end of the law, and the spiritual energy between heaven and earth is scarce, where is there still so much spiritual energy for Ou Haoyun to absorb.

In Ou Haoyun's Purple Mansion Dantian, the aura vortex that had just formed a liquid true element was originally formed, and when he wanted to condense the second drop of true yuan, the supply of spiritual energy was insufficient at this time. The second drop of True Yuan did not succeed in condensing for a long time, and slowly the aura vortex actually had a tendency to collapse.

Seeing that Ou Haoyun was about to fail to break through, at this time, the demon god essence blood in Ou Haoyun's dantian moved again.

The pure essence continued to flow out of the demon god's essence blood, turning into a surging torrent, rushing madly towards the aura whirlpool. Then he was sucked in by the aura vortex.

With the appearance of the burst of essence, the aura vortex finally stabilized, and at this moment, the aura vortex rotated even faster, and soon a drop of true yuan was formed at the bottom of the vortex again.

One drop

Two drops

……

One hundred and eight drops.

A full one hundred and eight drops of True Yuan were condensed. And that demon god essence blood didn't seem to have consumed much at all. I saw that it stopped spewing out essence qi and continued to levitate on the edge of the dantian.

At this time, the dark clouds that had dispersed outside condensed again, and I saw that the dark clouds in the sky turned into a shocking thunder and fell from the sky, and slammed towards Ou Haoyun.

"Boom"

With a loud bang, the earth-shattering thunder directly hit Ou Haoyun's body.

Immediately, a scorching smell emanated from Ou Haoyun's body, his hair stood on end, his body was black, and his body was even more purple and flashing.

"Give Me Death"

A real person who built a foundation suddenly attacked at the moment when the sky thundered Ou Haoyun. A flying sword slashed out at Ou Haoyun's vital parts.

At this moment, Ou Haoyun was the weakest, his whole body was pierced by the thunder, his body was paralyzed, and he couldn't move at all.

"Don't."

Looking at the sudden attack of Zhuji Zhenren, Ouyang Feng and Yu Xue let out a cry of pain, crying out sadly, they seemed to see the scene of their son being killed by Zhuji Zhenren.

"Ding"

The flying sword struck Ou Haoyun's body, making a crisp sound.

"Our son is all right."

Looking at Ou Haoyun, who was safe and sound, Ouyang Feng and his wife suddenly breathed a sigh of relief.

However, the real person who built the foundation was shocked.

"What, there is a magic weapon to protect yourself."

Seeing that his flying sword slashed into the opponent's body, it didn't hurt the other party at all, which made the Tsukiji real person shocked, and hurriedly slashed Ou Haoyun again.

"Hmph, you dare to sneak attack me, die!"

Ou Haoyun reacted at this time, shouted angrily, sacrificed the sword fetus and slashed towards the Zhuji real person, only to see a purple sword fetus slashing through the void, directly shattering the magic weapon of the Zhuji real person, and then slashing at the Zhuji real person's body.

"Forehead ......"

Looking at Ou Haoyun, the eyes of the real person who built the foundation were full of disbelief, and he couldn't understand why Ou Haoyun was able to react.

It's just dead and blind.

In fact, the reason why Ou Haoyun reacted so quickly was entirely because of the sword fetus.

It turned out that at the moment when Ou Haoyun was thundered, the terrifying power of heavenly thunder directly penetrated Ou Haoyun's dantian.

And the sword fetus seemed to have taken a stimulant at this moment, and when it saw the thunder, it pounced violently. A terrifying suction force came, and suddenly the thunder that rushed into Ou Haoyun's dantian was absorbed by the sword fetus.

Therefore, these days the power of thunder was not raging in Ou Haoyun's body at all.

"Old Ancestor, I killed him, I don't know if anything happened."

Looking at the ancestor, Ou Haoyun said very seriously. Although there is only one level difference between foundation building and qi training, but feeling the terrifying power coming from his body, Ou Haoyun found that after breaking through. At least, the strength has skyrocketed several times.

From the moment of breakthrough to the foundation building period, Ou Haoyun knew that he already had the strength to fight with the ancestor.

"Hey, Ancestor, I don't want to say anything more, you can do whatever you want, and I won't ask about this matter."

As he spoke, the ancestor put away his supernatural powers. The back is swaying, flying towards the back mountain of the Imperial Dao Sect, looking at its back, it looks very bleak.
