Lin Feng's eyes were closed, he didn't cultivate, he just quietly breathed.

The recovery of the spirit and spirit, the pills and other substances have no effect, and the only way to recover slowly is to rely on time.

Lin Feng estimated that before the battle between him and Shangguan Hao, it would be difficult for his spirit and spirit to recover completely.

Sou!

Lin Feng had just been sitting quietly for a moment when the figure flashed, and Gong Lin rushed in.

"Lin Feng, what do you want to do, let me out!" entered the palace of the stone house, stared at Lin Feng with anger on his face, and shouted loudly.

He suddenly entered this unfamiliar space, and his heart was shocked, but just now, he had already learned about the situation from the mouth of Wen Rentiandu outside, and knew that this place was among Lin Feng's spatial treasures.

But he didn't know why Lin Feng brought him here, and his heart was filled with anger, so he directly found Lin Feng.

Lin Feng opened his eyes, glanced at Gong Lin, and said lightly: "Aren't you waiting for Sikong Yan?

"Senior Brother Sikong is also here?"

Gong Lin was stunned when he heard this, and asked suspiciously, "Where is it?" Why didn't I find out?"

"He's cultivating, you just wait!"

Lin Feng didn't bother to say much to the other party, and with a wave of his hand, he waved a wave of qi and swept the other party out.

"You...... Damn!" Gong Lin let out an angry shout from his mouth, and he was directly waved by Lin Feng a hundred miles away.

Then, Lin Feng closed his eyes again, closed his eyes and breathed, like a petrified old monk, not moving at all.

Time passes like water.

Day after day, seven days passed in the blink of an eye.

Seven days later, Lin Feng opened his eyes and spat out a mouthful of turbid air.

After seven days of meditation, Lin Feng's spirit and spirit recovered slightly, and finally made him no longer feel so tired.

However, there is still a long way to go before the spirit is completely restored.

Although this had some impact on his strength, the impact was not too great, Lin Feng secretly estimated that he had only dropped by two percent of his strength at most.

However, with the explosion in the number of spirit vortexes, the strength of these two percent is not so important.

After bowing his head and pondering for a moment, Lin Feng decided to continue cultivating the Divine Vortex Secret Method.

Although it was said that the more spirit whirlpools, the greater the difficulty of breaking through, but Lin Feng still had some confidence.

First of all, he has a lot of hole cards, and his strength is not comparable to ordinary geniuses of the same level.

Secondly, he also has some confidence in the foundation of the Firmament Divine Palace, the primeval martial arts cultivation of the multi-spirit vortex, the biggest calamity to be promoted to the Martial King is the terrifying Martial King Tribulation.

And the Firmament Divine Palace, as the overlord of the ancient era, must have a lot of treasures against the sky, and when he gets a few more treasures, the Martial King Tribulation is not impossible to resist.

The most important thing was that Lin Feng was too eager to improve his strength because he didn't have much time left.

Of course, Lin Feng would not blindly increase the spirit vortex, he also had a measure in his heart, and adding a dozen spirit vortexes should not be a big problem.

Leaning less, Lin Feng took a deep breath and cultivated the Divine Vortex Secret Method again.

One by one, new whirlpools are formed.

Time passed, and after half a day, the number of spirit vortices in Lin Feng's body reached thirty-two.

Lin Feng's physical strength was against the sky, and he still didn't feel any pressure, but the condensation of his spiritual vortex was getting slower and slower.

"Do you want to continue?"

Lin Feng groaned in his heart, there were thirty-two spirit vortexes, and the number of such spirit vortexes was already shocking.

"Add some more!"

Lin Feng gritted his teeth, in the primeval era, someone had cultivated a hundred spirit vortexes, but he only had thirty-two, how could he just retreat!

Of course, Lin Feng didn't dare to cultivate a hundred spirit vortices, that person was crazy, he wasn't crazy.

But what Lin Feng didn't know was that even if he cultivated the thirty-two spirit vortexes, in the eyes of others, he was already completely crazy!

Lin Feng continued to cultivate the Divine Vortex Secret Method, and a spiritual vortex in his body slowly decomposed, one into two, two into four.

More than half a day had passed, and the number of spirit vortices in Lin Feng's body had reached forty-three.

At this time, Lin Feng finally felt the pressure, and every time the spirit vortex was added, dozens of spirit whirlpools were connected, generating a huge oppressive force that impacted his physical body.

However, this oppressive force was completely within Lin Feng's tolerance.

"Cultivate until you can't bear it anymore!" Lin Feng was ruthless, but he still decided to continue cultivating, reluctant to let the child trap the wolf, if he didn't cultivate to the limit, how could he be willing!

Besides, if he really can't break through to the realm of the Martial King in the future, he will give up a few more spirit whirlpools.

After that, Lin Feng continued to cultivate with his head bored.

Forty-four!

Forty-five!

Forty-seven!

Forty-eight!

When he cultivated to the forty-eight spirit whirlpools, Lin Feng was almost at the limit, and the huge and extreme oppressive power impacted his physical body, even if Lin Feng's physical body was strong, he couldn't help but tremble all over his body.

"The number of Dayan is fifty, and there are nine out of forty, so let's add the last spirit vortex!" Lin Feng decided to cultivate to forty-nine spirit vortexes, and then he no longer cultivated.

Thoughts sank into his body, and Lin Feng controlled one of the spirit vortices to slowly decompose.

This process was very slow, two hours had passed, Lin Feng was already sweating profusely, and the spirit vortex gradually decomposed into two parts, slowly forming two spirit vortexes.

At the moment when these two spirit vortices were formed, the forty-nine spirit vortexes were connected into one, forming an incomparably powerful qi machine, like an invisible wave, impacting Lin Feng's whole body.

Belch!

Lin Feng couldn't help but snort, the flesh and blood all over his body felt as if they had been cut by a thousand knives, and there was a heart-rending pain.

Lin Feng's body trembled violently, he gritted his teeth and insisted.

Finally, after three breaths, this powerful qi gradually dissipated.

Call!

Lin Feng let out a sigh of relief, forty-nine spirit vortices, which was enough, he was not ready to cultivate anymore.

Although he was sure that he could barely add another spirit vortex, he didn't want to make any more effort.

Forty-nine spirit vortices are enough to defy the sky, and the number of dark talismans is very perfect.

Then, Lin Feng took out about five million top-grade spirit stones and began to devour them, preparing to replenish all the mystical power of all the spirit vortexes in his body.

When the five million high-grade spirit stones were consumed, Lin Feng's face became a little gloomy.

Five million high-grade spirit stones were devoured, but it was not enough for him to stuff his teeth, and the forty-nine spirit vortexes in his body were still slightly empty, and the distance between them was replenished and filled, and the difference was 108,000 miles.

Lin Feng's head was a little big, when he used to have nine spirit vortexes, he often worried about spirit stones.

Now the number of spirit whirlpools has increased to forty-nine, and there will be more in the future! It is estimated that every time he improves his cultivation in the future, the number of top-grade spirit stones he needs will be billions!

Ay!

Sighing secretly, Lin Feng didn't bother to think about it, and continued to devour, but fortunately, he now had billions of high-grade spirit stones, which was completely enough for him to squander.

Piles of spirit stones were taken out, and they were constantly devoured, and when Lin Feng devoured about 200 million top-grade spirit stones, the forty-nine spirit whirls in his body were all filled.

"It's time to go, Ancient City!"

Lin Feng finished devouring, got up, and strode out of the stone house.

Lin Feng walked out of the stone house and saw the Qinghuo King sitting in the courtyard, in a daze.

"Little brother!"

Seeing Lin Feng walk out of the stone house, the Green Fire King suddenly stood up and looked at Lin Feng with a worried face.

He was miserable by Lin Feng, otherwise he would have escaped a long time ago, although he was resentful in his heart, he didn't dare to attack at all.

"Blue Fire King, do you remember what you said?" Lin Feng walked up to the Blue Fire King and asked with a smile.

Last time in the hell space, the Qinghuo King said the words of being a servant and a slave himself, and he was willing to save the other party.

If the other party dares to repent, Lin Feng doesn't mind asking for the other party's life now.

The Qinghuo King was silent when he heard this, he was only facing a dead end at that time, and he said such things in a hurry, how could he not want to regret it now?

He is a fivefold powerhouse of the Martial King Realm, if he becomes a slave of a Heavenly Martial Master, it will be a great shame.

However, now that he has been sealed, he doesn't even have the qualifications to resist.

The Green Fire King knew that if he regretted it now, it would be difficult for him to survive.

Taking a deep breath, the Qinghuo King looked directly at Lin Feng and said, "What I Qinghuo said, naturally I won't regret it!"

The Blue Fire King was ready to temporarily succumb to Lin Feng first, and then find a way to escape when he had the opportunity in the future.

Moreover, if Lin Feng died one day, then he would naturally be free.

"Good!"

Lin Feng showed a smile on his face when he heard this, and said softly, "Don't resist!"

With that, Lin Feng pointed his finger and instantly hit the forehead of the Green Fire King.

A wisp of mystic power was wrapped in his mind and entered the sea of consciousness of the Blue Fire King.

This wisp of thought can allow Lin Feng to control the Qinghuo King, and if the other party dares not to obey the order, he can immediately detonate this wisp of mystical power, blow up the other party's sea of knowledge, and kill the other party.

It is impossible for the other party to expel this wisp of Xuan power, because once the other party starts to expel it, Lin Feng's mind can immediately perceive it, and before the other party expells it, he can detonate the Xuan power.

At the beginning, Huang Fuqing's means of wanting to control Lin Feng were actually similar to this kind of means, but Huang Fuqing's means were not to threaten Lin Feng's life, but to perceive Lin Feng's location all the time.

"From now on, you are my slave!"

Lin Feng's face was indifferent, and he said in a deep voice: "You will serve me in the future and atone for your sins! If your performance satisfies me, I will return your freedom in the future, but if you dare to have a different heart, you will definitely die!"

"Yes!"

The Green Fire King nodded hurriedly, his face extremely respectful, but what he thought in his heart was diametrically opposite.

"Boy, it won't be long before I find a way to kill you, and then I'll let you know the old man's methods!" the Blue Fire King thought viciously in his heart.

An ant-like Heavenly Martial Artist actually wants to drive him, he simply doesn't know whether he is alive or dead!

"That...... Childe, shouldn't you help me unlock the seal of cultivation!" said the Qinghuo King with a hopeful face, he couldn't accept the title of master, so he called Lin Feng Gongzi.

Lin Feng nodded, and then couldn't help but speak, and his palm pressed against the abdomen of the Blue Fire King.

The Xuan Power surged, and Lin Feng's Xuan Power rushed into the Blue Fire King's body and began to break the seal for it.

The entire dantian of the Blue Fire King was sealed by Master Cui, but Lin Feng underestimated Master Cui's strength, and it took him nearly half an hour to break the seal that shrouded the Dantian of the Blue Fire King.

As soon as the seal was broken, the Green Fire King suddenly regained his strength, and the strong Xuan Power flowed through the meridians of his body.

The Qinghuo King, who had regained his strength, felt a big sigh in his heart, and he really wanted to slap Lin Feng to death immediately, but he still held back.

"Blue Fire King, are you familiar with the wasteland?"

Lin Feng asked the Qinghuo King, the situation of the underground gate last time was told to him by the other party, so he guessed that the other party must have a lot of knowledge about the wasteland.

"I've been here once a few years ago, so I know about it!" the Blue Fire King nodded.

"Then do you know about Ancient City?" Lin Feng asked again.

"Ancient City?"

When the Qinghuo King heard this, he said, "I know, I've been there once!"

"Okay, you take me to Ancient City!" Lin Feng smiled slightly.

Then, Lin Feng's mind swept away, and he saw that Wenren Tiandu and Gong Lin were both cultivating on the mountain peak not far away, so he didn't bother the two of them, and left the Void Realm Divine Map with the Qinghuo King.

......

Sou!

In the endless desert, two figures rose from under the sea of sand and flew into the sky.

"Blue Fire King, you lead the way!" Lin Feng said to the Blue Fire King.

The Blue Fire King nodded, and after identifying the direction, he flew forward.

Lin Feng followed behind the Blue Fire King and headed towards the Ancient City.

The Blue Fire King was extremely fast, speeding ahead, he turned his head and glanced at Lin Feng behind him, and there was a hint of sarcasm in his eyes.

Immediately, as he flew, he thought about how to solve Lin Feng.

This matter was easy for him, a mere Heavenly Martial Master Ninefold Martial Artist, he could trap Lin Feng with a little trick.

The two of them didn't say anything all the way, their bodies were like electricity, and they galloped above the sky, and the space was cut off everywhere they passed.

After about seven or eight hours of hurrying, the two finally approached the ancient city.

When Lin Feng saw the ancient city from afar, he couldn't help but be shocked in his heart, this was the real ancient city!

This city was so big that there was no end in sight, far surpassing all the cities that Lin Feng had seen before.

The majesty of this city, like a majestic peak standing on the vast earth, makes people feel small.

The city wall that is hundreds of feet high, lying between heaven and earth, is majestic, majestic and magnificent, and shocking.

However, the city is now in ruins, with large sections of the city walls and the buildings within them crumbling and in ruins.

There are still intact buildings in the city, but not a single one has been completed.

"Childe, this is the Ancient City!" "The Green Fire King looked at the huge ancient city in front of him and said to Lin Feng with a smile.

"Hmm!"

Lin Feng nodded, and then said to the Green Fire King: "Green Fire King, I came to the Ancient City to find a refining material called Tong Xuan Stone, if you can help me find this material, I will have a heavy reward!"

"Qinghuo must have found this material for Childe!"

When the Blue Fire King heard this, he immediately hugged his fist at Lin Feng, with a respectful look on his face, but he was very disdainful in his heart, a Heavenly Martial Master Martial Artist, he actually said that he would reward him again, it was really ridiculous.

"Well, let's go!"

Immediately, the two of them accelerated and flew towards the ancient city.

In a matter of moments, the two of them flew into the ancient city and landed down.

The ancient city was already dilapidated, and there was no large array to protect the city, so it was effortless for the two of them to enter the city.

Lin Feng's eyes scanned all directions and found that there were still many scattered warriors in the city, searching for treasures in the city.

Seeing this, Lin Feng couldn't help frowning, this city had basically been turned upside down, where were there any treasures!
