The Peak Manor of the Royal Dragon.

Back garden.

One hundred meters underground.

This is where the spiritual veins are located.

At this time, in the center of this spiritual vein, there was a space the size of a room, and Lu Zheng was sitting in it.

The surrounding aura was so dense that it almost condensed into substance, like smoke, constantly converging towards Lu Zheng's body.

After the spirit of the spirit vein crossed, this vein also matured.

All the ores have been converted into spirit stones, and to the spirit of the spirit vein, it is like a faded dead skin, and it is no longer of any use.

For Lu Zheng, it has a big effect.

Lu Zheng opened the way with a "peerless" sword and opened a 100-meter passage that led directly to the underground, and he has been in retreat here.

Now, Lu Zheng doesn't know how long it has been.

The aura in the entire spiritual vein was absorbed by him.

The true yuan accumulated in Lu Zheng's body has also reached a terrifying level.

It's a pity that Lu Zheng still hasn't broken through to the foundation building period!

Whew!

Lu Zheng slowly opened his eyes, and in his eyes, two lightning flashes disappeared.

Lu Zheng carefully examined the situation in the dantian and frowned slightly.

He had just broken through the realm of supernatural powers not long ago, and it stands to reason that the top priority was not to rush to break through, but to stabilize the realm.

After gradually adapting to this realm, it is not too late to make a breakthrough.

After a long time, Lu Zheng sighed, but decided to give up the urge to forcibly attack the foundation building period.

If you forcibly break through, you may also enter the foundation building period, but after all, if you can't do it naturally, it may leave hidden dangers for future cultivation.

This short-sighted approach is tantamount to drinking water to quench your thirst!

After giving up the breakthrough, Lu Zheng began to think of other ways to improve his strength.

The reason why Tianxing and others were not left in this battle in Yucheng was not left.

Maybe it's because of the lack of magic weapons, but it's also because Lu Zheng can use too few means!

Although he had countless secret methods and tricks in his mind, he had now reached the realm of supernatural powers, and all kinds of spells could be done at his fingertips.

However, what he was really good at was actually the several scattered magic seals that he had cultivated at the beginning.

These seals were still cultivated by Lu Zheng when he was in the Bitter Sea Realm, but now they are a little inappropriate to use.

Lu Zheng frowned and thought for a while.

Many tricks flashed through his mind, many of which were powerful, but they were all vetoed by Lu Zheng one by one.

Without him, it takes time!

Right now, what he needs most is time!

It's easy to refine these techniques within a month, but it's impossible to refine these techniques to a high depth and increase his combat effectiveness a lot!

"Hey, why did you forget it!"

Suddenly, Lu Zheng seemed to think of something, and his face suddenly showed surprise.

At the beginning, when he first used the Great Wilderness Fire God Furnace to refine the pill, he not only obtained the use of the Great Wilderness Fire God Furnace, but also obtained a very powerful pupil cultivation method - the Great Wilderness Fire God Pupil!

Cultivating to the depths of the sky, it can burn the sky, and even make the world repeat the flood!

As long as you cultivate to the first form of the Great Wilderness Fire God Pupil, you will have the power of the Samadhi True Fire that is not inferior to that of the immortal cultivators of the Jindan Period.

The key thing is that this pupil technique is not difficult to cultivate, but it is just ...... Need to endure inhuman suffering!

That is to use the Great Wilderness Fire God Furnace to refine the flesh!

It sounds simple, but the pain is far more than people can imagine, far more than a thousand cuts. And Lu Zheng calcined himself with a flame, which was tantamount to cutting himself off.

The pain is chilling to think about.

"That's you!"

Lu Zheng made up his mind in his heart.

Bang~!

With a thought in his mind, the Great Wilderness Away from the Fire God Furnace instantly turned into a big furnace and fell in front of Lu Zheng.

Lu Zheng used the spirit stone to set up a blessing formation under the furnace, and then shot out a flame, burning around the Great Wilderness Fire God Furnace.

And Lu Zheng himself jumped directly into the furnace.

Snort~!

With the blessing of the formation, the flames instantly burned and devoured Lu Zheng's body together.

Time passed slowly, and in the blink of an eye, a month passed in a hurry.

in the manor.

Every day, Gu Yun and Su Zimo would come to the back garden to check and wonder if Lu Zheng was out of customs.

Seeing that the January period had arrived, Su Zimo became a little anxious.

Gu Yun didn't know what was going on, but she knew what happened in Yunlong Manor that day. It is even more clear that Lu Zheng will definitely be in the imperial capital mountain.

"What should I do? Lu Shihe ......"

Su Zimo kept wandering around the garden with some anxiety.

"Zimo, is there something wrong with you? If there is something to do, go and get busy, and I'll wait for Xiao Zheng here as well. Gu Yun saw that Su Zimo's face was wrong, and comforted with a smile.

This month, thanks to Su Zimo's presence, she won't be bored.

It's a pity that Lu Zheng has already accepted Su Zimo as an apprentice, otherwise she would be quite satisfied with Su Zimo as her daughter-in-law!

Su Zimo smiled: "Auntie, I'm fine." I'm just a little worried about Lu Shi......"

Thundered~!

Before Su Zimo's words were finished, the entire ground suddenly trembled.

Then, the two of them felt that the temperature in the garden was rising at a strange rate.

Even the air smells scorching.

Sneer~!

Some of the flowers dried up directly.

"Oh no, it won't be Xiao Zheng and his ......" Gu Yun's face changed, and she said with some worry.

Rumble~!

Without waiting for Gu Yun's words to fall, two pillars of fiery red light, like two giant dragons, rushed out of the passage opened by Lu Zheng and rushed straight into the sky.

The entire sky was dyed crimson with these two pillars of light, burning into a sea of flames.

"Today, I enter the foundation!"

The moment the pillar of light disappeared, a loud whistle suddenly came from the ground, resounding in all directions.

Bang~!

Above the manor, it was as if a hurricane had blown into the sky, forming a huge mushroom cloud, which radiated colorful light under the sunlight.

"The clouds are steaming, covering the heavens and the earth! Lu Shihe...... Entering the foundation building period? ”

Su Zimo looked at the huge auspicious clouds above his head, and his pretty face was full of surprise.

When an immortal cultivator breaks through the foundation building period, he will not let the heavens send down thunderstorms, but will instead generate various visions.

The clouds in front of me are steaming, and the vision like a fairy in the dust is a sign of breaking through the foundation building period.

"Whoosh!"

A sound of breaking the air sounded.

Beside the two, there is already an additional figure.

It was Lu Zheng.

"Master Lu, have you broken through the foundation building period?" Su Zimo asked in surprise.

"Hmm~"

Lu Zheng nodded, with a look of joy on his face.

Originally, he had already given up the idea of forcibly breaking through the foundation building period, but he didn't expect that because of the cultivation of the Great Wilderness Fire God Pupil, his physical body had also undergone a tempering.

Breaking through the foundation building period, it is natural to come into being.

"How long have I been in retreat this time?" Lu Zheng looked at Su Zimo and asked.

"Master Lu, you've been in retreat for a month." Su Zimo replied.

Lu Zheng nodded, similar to what he had calculated.

After a night's rest.

Lu Zheng took Su Zimo and went north together.

Target, Imperial Capital Mountain!
