Mrs. Yuhua, who was overjoyed, happily gave Wu Hu four thousand taels of silver tickets, and also gave him a sign, so that he could come to the underground martial arts arena to find Mrs. Yuhua at any time in the future.

"With this money, I can cultivate with peace of mind."

Wu Hu estimated that after ten more days of penance, he would be able to complete the transformation of his skin, thus breaking through to the peak of the Forging Body Realm.

However, the premise was that he had to take a medicinal bath every day to speed up his cultivation.

After saying goodbye to Mrs. Yuhua, Wu Hu and Wei Tong left the underground martial arts arena, and after restoring their original costumes, Wei Tong couldn't help but breathe a sigh of relief.

To be honest, accompanying Wu Hu to the underground martial arts arena, he was under a lot of pressure, and he was always worried that Wu Hu would have an accident. Fortunately, Wu Hu was strong, but there was no problem.

"Wu Hu, you are much stronger than I was back then." Wei Tong had participated in the duel in the underground martial arts arena and knew the danger involved.

Although the people who went to the ring were all martial artists in the forging realm, Wei Tong would definitely not look down on him today. But those people were like fighting beasts, very fierce, much stronger than ordinary Body Forging Realm martial artists.

"Do a good job, and the future is limitless!" Wei Tong patted Wu Hu on the shoulder, if he only regarded Wu Hu as a junior brother before, then now Wei Tong has regarded Wu Hu as a future powerhouse.

He has seen Wu Hu's strength, such a person will not be bad in the future, at least stronger than him.

"Hmm!" Wu Hu nodded and returned to his residence.

Next, Wu Hu focused his attention on cultivation, except for going out to perform patrol tasks, he was immersed in penance.

This allowed his strength to progress rapidly, and it only took him eight days to complete the transformation of his skin.

I saw that Wu Hu's epidermis quickly fell off, and a new layer of skin grew again, like jade.

Wu Hu tried it with a knife, but he couldn't hurt himself at all.

"Invulnerability, real invulnerability. Unless the martial artist of the Qi Sea Realm makes a move, he won't be able to hurt me! ”

Wu Hu's face was full of joy, which greatly improved his defense. Even in the face of a Qi Sea Realm martial artist who has cultivated his true qi, he can resist for a while.

"Now that I have broken through to the peak of the Body Forging Realm, the next step is to cultivate the Qi Sea Realm exercises, absorb the spiritual energy between heaven and earth and transform it into true qi, and use it to open up the Qi Sea."

Now that Wu Hu has the medium-grade Qi Sea Realm Exercise Thunder Fire Decisive rewarded by Li Qingyi in his hand, Wu Hu is thinking about whether he can synthesize this exercise and obtain a super-grade martial arts.

With the example of Vajra Barberry Fist synthesis, Wu Hu already had a plan to find scriptures to use to synthesize with Thunder Fire Duel.

What is needed is not necessarily the supreme scripture, but the main thing is to adapt to the thunder and fire, so that the synthesis effect will be good.

While the patrol was over and resting, Wu Hu was ready to go to the market to see if he could buy suitable scriptures.

It's just that Wu Hu got the news as soon as he went out that Heiyun Castle wanted to let a newcomer like him go to the mine to help, in the name of training them newcomers.

But Wu Hu knew very well in his heart that this was all an excuse. The main reason is that those children of the Li family want to be lazy, so they will desperately call a newcomer like him.

Wu Hu had no choice but to give up the plan to buy scriptures and go to the mine to help.

It turned out that after the collapse of the No. 3 mine, the production of Yan Iron declined. In order to ensure production, the mine is working day and night, which will lead to a shortage of manpower.

As a martial artist, Wu Hu's task is to patrol the mine to ensure that there are no accidents. As for the miners, they just have to keep their heads down and work hard.

In the middle of the night, Wu Hu was really uncomfortable and ran out of the mine.

"Go pee!"

As a result, as soon as he came back, he met Li Wu.

"Dare to be lazy!" Li Wu recognized Wu Hu at a glance, and he dared to contradict his own kid before.

"I'm just coming out for convenience!" Wu Hu explained.

"Hmph, dare to quibble, you don't have to carry out patrol tasks in the next half a month, you will all come to the mine!" Li Wu snorted coldly and said, directly letting Wu Hu work as a coolie in the mine for half a month.

"Hehe, if you are not convinced, you can go to the castle master." As a child of the Li family, Li Wu has no fear.

There were still people watching around, and Wu Hu had no choice but to obediently enter the mine.

Sure enough, Wu Hu soon received an order that he would work as a coolie in the mine for half a month.

For this reason, Yuan Chong lost his temper, but in the face of the children of the Li family and the lord of Black Cloud Castle, he returned in vain.

The only good news is that Wu Hu took the time to go to the market for a while, and it really made him discover something good, the Book of Heaven and Earth. This is a Taoist scripture, and it is very suitable for the Thunder and Fire Battle.

After Wu Hu synthesized it, he obtained the Super Qi Sea Realm Martial Arts Heavenly Thunder and Earth Fire Decision, and used the Heavenly Thunder and Earth Fire as a furnace to temper his body. Although it is a martial art of the Qi Sea Realm, the focus is still on the path of physical strength, which can be regarded as inheriting the advantages of Wu Hu's cultivation of Vajra Barberry Boxing.

But after all, it is a super-grade martial art, and after cultivation, the true qi is still extremely powerful. It's just that in comparison, the effect of physical blessings will be more terrifying.

"There is volcanic lava in the mine, isn't this a proper earth fire, just right for me to cultivate."

Wu Hu didn't expect that he would be blessed by misfortune and have an excellent place to cultivate.

After a quick tour of the cave, Wu Hu found a place close to the volcanic lava and began to cultivate.

He sat down cross-legged and struck the earth.

Gradually, he could clearly feel the rich scorching aura around him.

The aura attributes between heaven and earth are different, and they are all mixed together. But in special places, some aura is extraordinarily strong. For example, near the volcanic lava, the aura of the fire attribute is particularly rich.

In such an environment, Wu Hu, who cultivated the Heaven and Thunder Fire Decision, naturally achieved twice the result.

After running the exercises, he could absorb the surrounding fire attribute aura, let it run in his body according to a specific meridian for a week, and transform it into extremely pure energy, which is true qi.

These True Qi would continue to operate in Wu Hu's body, constantly strengthening his body. In the end, they all gathered towards his dantian and slowly moistened here.

Over time, you will be able to open up a space in the dantian to store true qi, and this is the sea of qi.

After the sea of qi is opened, it is necessary to open up the qi hole. These qi points can absorb true qi and create a connection with the sea of qi. Let the space of the sea of qi become larger and more stable, so as to have a more majestic true qi.

Among them, there are 12 qi points in the human body, four of which are the main qi points and the rest are secondary qi points. Every time you open up a main qi acupoint, you can break through your own realm, but if you can open up more secondary qi acupoints, you can have a more majestic true qi.

Generally speaking, those who get through seven or eight are already geniuses, those who get through ten are family Tianjiao, and those who get through eleven are unborn people.

As for the twelve, they exist only in legends.
