From early morning to six o'clock, that is, when the city is in spring, the attributes of the underground immortal veins are mainly wood and water. Among them, the first three hours are mainly the water attribute elemental force, and the last three hours are mainly the wood attribute elemental force. Therefore, at this time, martial artists who are good at water and wood exercises are the most comfortable to cultivate. The combat effectiveness of the water system martial arts is not strong, but it has a certain healing ability. The wood attribute exercises are mainly winding, and the lethality is weaker, but the healing ability is stronger.

The period from six o'clock to nine o'clock is the first half of summer, and the fire attribute Yuan Force is the main one. The destructive power of the fire-based exercises is strong and the coverage area is also light, but the martial artists who practice the use of the fire-based methods are generally short-tempered, and many people are still bald or even bald.

Du Feng also practiced fire-based exercises, and he practiced very advanced exercises of the Feng clan, but fortunately, he was not bald, let alone bald. At this time, it was already past nine o'clock, and the yuan power of the fire attribute began to transform into the thunder attribute, and he still understood the thunder system exercises. Seize the time to absorb the underground Yuan power, so that the meridians and limbs in the body can be replenished.

"Zlazra......"

The Yuan Force of the Thunder attribute is relatively strong, so the scars on the stimulated Du Feng meridians and dantian are a little painful. It would be nice if I came earlier, the water attribute and wood attribute Yuan Force are the most suitable Yuan Force for healing. But it doesn't matter, Du Feng can still bear this little pain.

By the way, Xiao Hei likes the thunder attribute Yuan Li. Du Feng simply released Xiao Hei and let him experience the Yuan Power of the Heavenly Realm, which was different from the Nether Realm.

"Cool, this is fairy power. ”

Xiao Hei is right, the Yuan Force of the Heavenly Realm is called Immortal Power, of course, it can also be understood as a high-level Yuan Power. After all, all the energy that can be absorbed and utilized can be called Yuan Li.

"yes, don't be in a hurry to sleep yet, and then sleep when I'm healed. ”

Du Feng knew that every time Xiao Hei was full, his favorite thing was to sleep. It is still at the twelfth level, which is equivalent to the cultivation of the Great Perfection of the Human Martial Emperor Extreme Realm. It's just that the combat power of the divine beast unicorn is strong, so it can compete with the martial artists of the Heavenly and Human Realm.

Now that he has absorbed such a high-level Yuan Force, he may fall asleep for a while. If it sleeps, there will be no one to control the ghost servant, and no one will be Du Feng's bodyguard.

"Don't worry, I can't sleep with this little thing. When you're healed, give me some fairy stones. ”

Last time, Xiao Hei ate the immortal stone and entered the sleeping period, and this time he is afraid that he will need a large amount of low-grade immortal stone holdings. Du Feng had already thought about it, and when he recovered from his injuries, he would exchange it for Xiao Hei to exchange for some medium-grade immortal stones. When he woke up after counting the sleeping period, it would be a thirteenth-level demon beast. At that time, those demon beasts outside, even if they are at the peak level of the ninth layer of the Heavenly and Human Realm, will not be enough for it to slap in the face, and the level of the Earth Immortal Realm will be able to compete with one or two.

In this way, one person and one beast practiced together in the master bedroom by absorbing the thunder attribute yuan power that came up from the ground. Du Feng knew that in the whole house, only the master bedroom had the most sufficient Yuan Li. He didn't ask Su Sushu to practice, not because he was stingy, nor because he was afraid that men and women would not kiss him.

It was because of Su Sushu's cultivation at the third level of the Emperor's Extreme Realm, she couldn't absorb such a rich Yuan Force at all. If it is forcibly absorbed, it will block the meridians and cause the cultivation to regress, and in serious cases, it may explode and die.

Thinking that there are such good resources in the immortal city, there are still so many martial artists in the shantytown who stay in the second and third layers of the heavenly and human realms and don't go into it much, it seems that their qualifications are relatively poor. As for a child like Zhou Jianqiang, the cultivation of the Great Perfection of the Emperor's Extreme Realm can't even absorb the free Yuan Power of his own family.

Du Feng was addicted to practicing, and soon the time exceeded twelve o'clock at noon, and he began to transfer to the autumn of Four Seasons City. The underground force in autumn is dominated by wind attributes and metals. The lethality of the wind system exercises is okay, although it cannot be compared with the fire attribute, but it is stronger than the water system, wood system, and earth system exercises. Its main feature is that it is very fast. Therefore, martial artists who practice the Feng system exercises are generally very good.

From twelve o'clock in the afternoon to three o'clock in the afternoon, the main thing that came up from the ground was the wind attribute Yuan Force, and Du Feng simply ran the wind system exercises. Xiao Hei didn't get used to that thing, so he had to retract into the small world of necklaces first. At this moment, Du Feng's advantage of being able to adapt to any attribute exercise was visible.

Like a practitioner of fire-based exercises, he can absorb the fire attribute elemental force, and the thunder attribute elemental force can barely absorb it, but the effect is slightly worse, and the wood-attribute elemental force is also barely absorbed, and the effect is even worse. As for the water attribute element power and the cold attribute element power, they would never absorb it, and that would only damage their cultivation.

The practitioners of the water system exercises are just the opposite, they can absorb the water attribute element power, and the cold attribute element force can also absorb it. But the fire attribute yuan power and the thunder attribute yuan power, that is something that you will never dare to absorb. It's the wood attribute Yuan Force, and it's okay for them.

By the time three o'clock in the afternoon had passed, the underground elemental force had changed like metallics. The gold lord kills, so the gold system exercises are the most lethal. Especially for sword cultivation, the golden system Yuan Force is simply too useful. Du Feng is no exception, his strongest attack method is the sword technique, so he naturally has to absorb more metallic yuan power.

"Buzz ......"

At this moment, the dragon sword placed in the small world of the necklace buzzed and vibrate. Du Feng understood at a glance that it was the swordsman who also wanted to come out and absorb the metallic elemental force. In that case, let's take out the sword.

"Thank you, master!"

After the dragon sword was placed on the ground, it really began to frantically absorb the metallic elemental force. The swordsman who lived in the Dragon Sword did not forget to thank this good master.

"You're welcome, just keep an eye on the hour. ”

In fact, Du Feng is sometimes quite embarrassed, if it is a sword that is usually forged from metal, it will be forgotten. The sword he is using now is the sword man's transformation. In other words, if the weapon is scrapped, then the sword man will also die, which is similar to killing a human life.

But right now, his best weapon is the Dragon Sword, and this sword can continue to grow, so he is really reluctant to replace it. can only try to create good conditions for the sword man, hoping that he can grow higher and faster. I think that the swordsman who created the world of swords in the first place is a famous fairy sword in the heavenly realm. If the swordsman in the Dragon Sword can grow to that extent, Du Feng plans to let him go and let him create his own world.

Du Feng didn't know these thoughts, and at this moment, he was desperately absorbing the metallic yuan power that came up from the ground. The dragon pattern on the sword body also shone brightly. From the moment he was born, the swordsman decided to find a master to fight the world together. He was optimistic about Du Feng, the master, and had no intention of leaving at all.
