Above the Sand Sea.

Go back in time.

Just as Lu Chen's flesh and blood body approached the Flame Palace and attacked the Flame Palace with the sword intent of the Excalibur, the entire sea of sand shook violently.

In the sea of sand, the figures scattered all over the sea of sand and unable to contact each other are all aware of the turmoil in the sea of sand.

They were stunned, and they didn't know what terrible changes had taken place in the sand sea, causing the entire sand sea to shake.

There are people from all walks of life in the many figures, such as Yun Yaoguo's Yan Yu, and like the colorful wind of Bingfeng City.

Sensing the shock of the sand sea, many people were frightened at first, but after calming down, they rushed to the source of the shock one by one. They believe that the heavens and the earth have changed dramatically, and there will be a treasure born.

Only a very small number of people walk in the opposite direction of the source of the shock.

Yan Yu was also one of the people who rushed to the source of the shock, and he even vaguely felt that the sand sea shock was related to the disappeared Lu Chen.

In a place in the sea of sand, Caifeng hesitated for a moment, and then rushed to the source of the shock.

As a result, she had lost her direction at the moment, and she didn't know how long she had been lost in the sea of sand.

Second, if there are other people in the sea of sand, there will definitely be people who go to the source of the shock to get a glimpse. She rushed to the source of the shock, and if she was lucky, she might be able to meet Han Yilu, the city lord of Ice Peak City, or Caiyu. Even if they can't touch Han Yilu or Caiyu, the people of the three cities have formed a temporary alliance at this moment, and it is not bad to meet the people of Bloody Demon City and Black Yao City. When the time comes, even if you can't get out of the desert, the chances of surviving in the desert will be greatly increased.

Caifeng didn't know that although there were people from all sides in the sand sea, not all the people from the five directions had descended into this vast sand sea, such as Han Yilu, Caiyu, Xiao Leyou, Yao Xinyue, Hong Ding, Wu He and others.

......

In an underground cavern in the middle of the sea of sand.

Lu Chen was still refining the black body of evil thoughts in the purple soul puppet with the fire of the sun.

I don't know how long later, he suddenly felt a bulge in his lower abdomen.

When his lower abdomen bulged more than ten times, he suddenly felt relaxed again. It was as if a shackle in the body had been untied, and there was a burst of relaxation all over the body, and an indescribable joy was inexplicably born.

He secretly realized, and suddenly understood, this is another transformation of the dantian qi sea!

The Dantian Qi Sea was transformed again, which meant that he could once again cultivate the Heavenly Position Meridian Diagram in the True Gang Technique of the Divine Sword, open up more meridians, and then step into the True Gang Triple Heaven Realm.

I didn't expect that the dantian qi sea would transform again at this time, and Lu Chen was slightly happy in his heart. After thinking about it, it suddenly came over. During this period of time, resisting the scorching of the supreme yang fire, the Gang Qi in his dantian qi sea had already consumed ninety percent of it. He was squeezing the sea of dantian qi all the time, squeezing himself, and obtaining more Gang Qi to maintain the operation of the Gang Qi hood.

It was this period of hard squeezing that made the dantian qi sea break through the limit once, and then transform.

It's just that it doesn't matter if he starts cultivating immediately, he still needs to refine evil thoughts.

Moreover, even if he finished refining evil thoughts, he would not be able to cultivate immediately. Opening up the meridians requires enough Gang Qi support, and at this moment, the Dantian Qi Sea can be described as empty, and the remaining Gang Qi can allow him to persist until the soul puppet is refined.

Of course, it wasn't that he didn't want to restore the consumption of the dantian qi sea, but although there were many spirit stones in the storage bracelet, they didn't match his attributes.

Cultivating with the help of spirit stones with incompatible attributes, everything is done, and it will also endanger one's own cultivation.

Unable to cultivate at the moment, Lu Chen didn't think much about it, and continued to refine evil thoughts with the help of the fire of the sun.

At some point, the terrible howl of the evil thoughts in the soul golem that only the soul could hear disappeared.

As wisps of black qi escaped, the black body of evil thoughts in the purple soul puppet that was bound by countless blood-colored silk threads gradually shrank and gradually became translucent.

At this time, another wisp of black qi escaped out, and before the black qi could fly away from the soul puppet, it was burned out by the fire of the sun.

The black body of evil thoughts became completely transparent in color, almost the size of a dragon's eye, and in the shape of cloud cotton.

Evil thoughts have been refined!

Lu Chen secretly breathed a sigh of relief, and the qi in the sea of dantian qi was about to run out. If the refining was not completed, he could only sacrifice the dragon qi cover to resist the fire of the sun.

Homing.

Suddenly a purple light flashed out of the raging flames in front of him.

In front of his eyebrows, the Dragon Gate of Zhihai had already opened, and the soul puppet rushed to return to the center of Zhihai.

"Double-check. Gu Linglong reminded.

Lu Chen nodded slightly, even if there was no reminder from Gu Linglong, he would check it carefully.

With a thought, the purple villain above the sea of knowledge slowly sank, and finally all of them submerged into the sea of knowledge. He scrutinized it and did not let go of any suspicious spots.

Half a day.

Lu Chen still closed his eyes tightly, but a not weak soul fluctuation escaped from his eyebrows, rippling in all directions.

This burst of soul fluctuations was very similar to the soul impact that the evil thoughts had cast before.

Sensing this soul fluctuation, Gu Linglong was slightly stunned at first, secretly thinking that the evil thoughts had not yet been refined. But after a deep sigh, she relaxed again.

After another moment, Lu Chen slowly opened his eyes.

"How's that?" asked Gu Linglong.

"Haha, it's never been better!" Lu Chen smiled, and a bright light bloomed in his eyes.

"Evil thoughts have been completely refined by the fire of the sun. Comparing the two, I realized that now my control over the soul puppet is truly like a finger. And beyond that, there's an even better thing. Lu Chen deliberately stopped talking, wanting to surprise Gu Linglong.

"You've mastered soul shock. Gu Linglong took over the conversation and said lightly, looking like I know you best.

"You already know?" Lu Chen looked surprised.

After thinking about it, he was relieved that he had just tried to perform a soul blast before he was sure that he had indeed mastered this powerful and mysterious attack. Gu Linglong was on the sidelines, and he must have sensed the soul fluctuation that he had just escaped. And the idea of refining the evil idea of the Yang Fire was actually put forward by Gu Linglong, and at this moment, it was normal for Gu Linglong to be able to guess his harvest through that burst of soul fluctuations.

Lu Chen originally thought that if he used the fire of the Extreme Sun to refine evil thoughts, the attack methods of soul impact would disappear as the evil thoughts were refined.

But the result was unexpected, after the evil thoughts were completely refined, a dragon's eye-sized soul energy mass was formed. After a closer investigation, he found that there was a secret of performing soul impact in the soul energy group. He immediately analyzed the drill with the power of sea knowledge, and quickly mastered how to perform soul impact.

Then he tried, and he was able to cast a soul impact.

"Let's go. Gu Linglong urged.

She didn't leave before, because she was unwilling to leave empty-handed. Now that they are sure that they can't enter the Flame Palace, and Lu Chen has finished refining the soul puppet, they can't return empty. Moreover, Lu Chen spent a lot of time refining the soul puppet, and during this period of time, Gu Linglong had nothing to do and felt very bored. Now that she could leave, she naturally didn't want to spend any more time in the cramped underground cavern.

Lu Chen nodded slightly, it was indeed time to leave the underground cavity.

He turned to look at the perimeter of the underground cavern, and could clearly see signs of quicksand swirling under the light of the raging flames.

Many quicksands converged in all directions like a whirlpool towards the Flame Palace.

It was one of the quicksands that had brought him into this underground cavern before, and now that he was about to leave this place, he naturally thought of the quicksand.

And if you want to leave the underground cavity, you must deal with the quicksand around you.

What's more, through the exploration and analysis of the gold runes on the Flame Palace through the power of sea knowledge before, Lu Chen sensed several very important information.

This underground cavern is located in the middle of the sand sea, and the Flame Palace is actually the center of the entire sand sea, and it is also the core of the entire sand sea.

The Palace of Flames connects the entire desert through quicksand.

He carefully observed the signs of the quicksand vortex turning, and suddenly his eyes lit up.

Not all of the quicksand in the quicksand vortex converged towards the Flame Palace, and many of them started from the Flame Palace, swirling in reverse and quickly spreading out towards the periphery of the Flame Palace, and the quicksand that swirled in reverse led to the unknown distance of the Sand Sea.

After a deep sigh, he suddenly understood that the Flame Palace in the underground cavern was connected to the entire desert through this quicksand that swirled forward or backward.

If the quicksand he encountered before was the reverse quicksand, he would have been carried to the outskirts of the desert by the quicksand, not to mention discovering the underground cavity in the middle of the sand sea.

After deciding on the way to leave, he did not leave in a hurry, but thought about it.

Suddenly, he took out a spirit-level treasure weapon long sword from his storage hand.

After some sacrifice, Lu Chen hid a mark condensed by his sea knowledge power in the spirit-level treasure sword.

Then, he inserted this spirit-level treasure longsword into the very edge of the underground cavern.

At the very edge of the underground cavity, the imprint of the power of sea knowledge left in the spirit-level treasure weapon sword can be maximized to avoid the scorching of the supreme sun. At the same time, it can also allow the imprint of the power of the sea to remain next to the Flame Palace. The reason why Lu Chen did this was to mark the specific location of this Flame Palace.

First, he can't open the palace portal and enter the Flame Palace to get a glimpse of it now, which doesn't mean that he won't be able to enter the Flame Palace in the future.

Leave a mark of the power of sea knowledge, so that you can find this underground cavity in the future.

Second, the Bloody Demon City, the Black Yao City, the Ice Peak City, the Cloud Yao Kingdom, the Heavenly Wolf Country, the Yan Yuan Kingdom, the Shattered Cloud Army, and all the people and horses entered this dangerous secret place together, making the situation in the secret place complicated and difficult to understand. Just because he can't enter the Flame Palace doesn't mean that others can't enter the Flame Palace either.

At critical moments, this palace of flames under the sea of sand can be used as a bargaining chip to trade with people.

Furthermore, if the quicksand could not take him out of the sea of sand, he could still determine the general direction of the future through the imprint of the power of the sea of knowledge left here.

In the end, it's always good to have more means.

Gu Linglong was surprised by Lu Chen's actions and asked.

Lu Chen explained his many considerations one by one, and after Gu Linglong listened to it, he nodded secretly in his heart, feeling that Lu Chen's measures were indeed very safe and necessary.

When everything was ready, Lu Chen spotted a quicksand that swirled in reverse, and then he jumped up and rushed into the quicksand.

As soon as you enter the quicksand, the heat subsides and the pressure increases dramatically.

"Click!

The flesh erupted with a burst of sounds, as if it was about to fall apart. After having an experience, Lu Chen responded indifferently at this moment.

In the quicksand, he remained motionless, allowing this reverse swirling quicksand to take him to an unknown distance.

Lu Chen thought to himself that if this quicksand could bring him to the outer perimeter of the sand, he would be able to leave the sea of sand without spending a trace of his own strength.

That way, he doesn't have to deal with other people and doesn't have to worry about conflict with people.

And at this moment, his dantian qi is empty, and he has completed another transformation, it is best to find a secluded place to recover and cultivate first.

As for the idea of exploring the sand sea, he was not at all interested.

The palace of flames in the underground cavern is actually the biggest secret in the sea of sand, and after seeing the biggest secret in this sea of sand, he has little interest in other magical things in the sea of sand.
