The extremes of things must be opposed, and fire is the most yang thing. The highest form of fire is called the sun. And the extreme of yin is called Taiyin.

The solitary yang is not born, and the solitary yin does not grow.

This is the eternal and unchanging law of nature.

This place can give birth to Taiyin Jinzhi, and grow to more than 100 years, indicating that it must be the land of extreme yin.

If Chu Feng's Nine Yang Alien Fire wanted to be promoted, it needed to devour the Taiyin energy that had accumulated over thousands of years in this Extreme Yin Land. It's like oil from the ground, poured on fire, which can instantly raise the flame.

The Taiyin energy accumulated in this underground, like oil, does not seem to be a flame.

However, it can enhance Chu Feng's Jiuyang Alien Fire.

He had previously manipulated the Jiuyang Alien Fire to enter through the pipe, with only one purpose, that is, to draw out the Taiyin energy accumulated underground.

When he saw the green phosphorus fires, he knew he had guessed correctly.

There should be a lot of Taiyin energy accumulated in this underground.

......

Time passed little by little, and in Chu Feng's soul sea, there was an orange-yellow flame that kept beating.

This is exactly his Jiuyang Alien Fire.

Originally, this spark was only the size of a sesame seed.

At this moment, it has grown to the size of a soybean. It's more than 10 times more.

And the color is also darker, indicating that its fire temperature has also increased a lot.

The green phosphorus flames that emerged from the ground became less and less, and in the end, they were completely gone.

Chu Feng was very tired from refining these Taiyin energies, and sat with his eyes closed for nearly two hours before he slowly opened his eyes.

"Visible!"

I saw that in the palm of his outstretched right hand, an orange-yellow flame burst out. The Nine Yang Alien Fire that was summoned before was the size of an egg at most.

If you want to refine a medicinal herb, it is very difficult.

Now it's different, it's two palms the size. It's more than ten times larger than before.

If you look closely, you can find that the Jiuyang Alien Fire in Chu Feng's hand is like the annual rings of a tree, stacked together one by one. If you count it carefully, there are as many as nine layers from the fire heart to the outer flame.

"My Jiuyang Alien Fire was originally the worst first-order. This time, he absorbed enough Taiyin energy, and suddenly rose to the seventh order of the first grade, and he was fully promoted to the seventh order. ”

"The temperature has also increased from about 100 degrees to 700 degrees. ”

A happy smile appeared on Chu Feng's face.

I thought it would be good to be able to raise one or two orders at most. I didn't expect it to be a full five orders more than expected.

The ascension of different fires is by no means as easy as imagined.

Every product has a ten-order.

Even if it is only a level of ascension, the energy required is beyond imagination.

The Taiyin energy accumulated in this feng shui treasure land is at least more than 10,000 years. And there's no loss.

Therefore, after Chu Feng absorbed them, he was able to raise the Nine Yang Alien Fire to the seventh order.

"My current alien fire, killing the Great Sword Master level, shouldn't be a problem. ”

Chu Feng's alien fire has been greatly improved, not only has his alchemy ability been strengthened, but his ability to kill enemies has also been greatly improved.

In the past, his strange fire killed the swordsman level, and there was no problem.

If you want to deal with the swordsman, it's very reluctant.

As for the level of the Great Sword Master, Chu Feng's strange fire is really not enough to see.

The mysterious woman in black, Chu Feng couldn't deal with it. But now, he is fully capable of burning the woman in black with a strange fire.

"It's time to go back, too!"

Chu Feng stood up, patted the dust on his body, and prepared to leave.

He faintly heard in his ears the horse he was riding, snorting and snorting.

"Could it be that there is a coyote or something like a coyote in this mountain that has approached my horse?"

Chu Feng suddenly became vigilant, his cultivation was very weak, and he had to be careful. Especially in this inaccessible mountain forest.

After finding the cemetery, Chu Feng deliberately kept an eye on it and tied the horse to an open area in the distance. One is to prevent the horses from being attacked by snakes, insects and beasts in the mountains, and the other is to attract the attention of the enemy.

He immediately crept to the place where the horse was tethered.

As he approached the position where the horse was tethered, a faint murderous aura permeated the mountains and forests. With Chu Feng's experience, he immediately deduced that there was an enemy or a fierce beast ambushing nearby.

Just waiting for himself to appear, the other party immediately killed himself.

Now that he noticed it, Chu Feng naturally wouldn't show up stupidly. He found a hidden high ground, hid his form, and watched what happened.

The mountains and forests are very quiet, and occasionally birds chirp twice when they pass by in the sky.

If there is an enemy lurking around this and trying to kill him, you have to be patient with them.

Time passed little by little, and those enemies who were lying in ambush were more patient than Chu Feng. It has been lurking all the time.

Chu Feng regretted it a little.

If you knew earlier, you would have refined a few more Flame Burst Pills.

The only one, in order to kill Mr. Luo, has been used.

He didn't have a single pill on his body, not even an elixir to escape.

This is extremely disadvantageous.

It's getting dark, and night is about to fall. From time to time, there was a roar of beasts, coming from the depths of the mountains and forests.

At night, it is the world of beasts.

All the beasts will run out and move in search of food.

Finally, the enemy's patience was worn out by Chu Feng. I saw a bush of firewood and grass in the distance, and it moved. Immediately afterward, two men with indifferent faces wearing hats woven of vines on their heads emerged from within.

"Ma, that kid shouldn't die in the forest, right?"

"It was getting dark, and I didn't see him come out yet. Don't you know that this mountain forest is especially dangerous at night?"

One of the lurkers, swearing.

"Maybe we realized that we were going to kill him, so we deliberately hid! We got the order of Prince Liu Ping, and we must get rid of that kid surnamed Chu in this deep mountain and old forest. Never again. ”

"That's a bit of a problem!"

The other kept scanning the surroundings, searching for Chu Feng's traces.

"Today, I will dig three feet into the ground and find out that kid. You have to see people in life, and you have to see corpses in death, otherwise it will be difficult for us to go back. ”

The two of them didn't even notice that the prey they were about to get rid of was staring at them not far away.

When they came out of the bushes, they kept deliberating.

"This Dujian Peak is not only deep and dense, but also very wide. Trying to find that kid surnamed Chu is really like looking for a needle in a haystack. "The cultivation of the two is not weak, and their actions are vigorous.

Before this, the two of them went up the mountain to search, but unfortunately they didn't find Chu Feng.

So, they pretended to be clever and hid their bodies around the tethered horses, waiting for Chu Feng to come and ride the horses.

They can kill and kill Chu Feng in one fell swoop.

The two kept walking forward, and before they knew it, they had reached the big tree where Chu Feng was hiding.

At this moment, as long as the two of them raised their heads, they could find Chu Feng.

"If you want to kill me, then kill them first!" Chu Feng's strange fire increased significantly, and he just tried his hand with these two people.

A wisp of Jiuyang fire came out of his fingertips, and he spotted the opportunity and flicked at the person in it.
