Chapter 728 Breaking through the bottleneck!

Three days later, Wei Hong quietly left the Spirit Plant Garden again.

For the sake of safety, he chose to leave through the tunnel again this time.

After leaving the Spirit Plant Garden, he changed his appearance and restrained his breath. Then he went to Cangshan Immortal City to buy a book on basic refining and advanced refining skills. He also bought a large number of low-level refining materials. At the same time, he also purchased a large number of materials and resources that he lacked. Then he returned to the Spirit Plant Garden.

This time, he spent half of the seven or eight thousand medium-grade spirit stones he had just received.

"Alas, it is indeed easier to spend money than to make money. This amount of spirit stones has only been received for a few days, and more than half of it has been spent in a blink of an eye. The four arts of cultivating immortals are indeed big spenders!"

Wei Hong, who returned to the secret room, couldn't help but sigh.

It's just that he said it, but he didn't feel the slightest bit of pain. Not to mention that these spirit stones were originally a windfall, and buying materials was also for practicing his own craftsmanship. This was definitely a hundred benefits for him and no harm. How could he be stingy?

So Wei Hong first took out the book of basic explanation of refining and read it carefully.

In less than half an hour, the system included the refining technique.

Then he continued to study advanced refining skills, and let the system improve the grade of refining techniques.

Half a day later, Wei Hong slowly put down the jade slip in his hand.

"I didn't expect that the way of refining is so profound and even vast. There are hundreds and thousands of basic refining techniques alone, and there are also various runes to choose and match, the control of fire and the ratio of materials, etc., all of which are difficult to learn and master. If there is no vitality point, I estimate that it will take five or six years to get started."

After a simple understanding of the way of refining, Wei Hong couldn't help but sigh.

Only then did he truly understand why among the four arts of cultivating immortals, alchemy and refining were the most expensive skills.

It was because the skill of refining was too complicated and difficult to understand, and it was difficult to learn and master. It also took a lot of time to practice and comprehend, and the most important thing was practice.

For example, the most basic refining technique, each refining material needs to be refined before it can be refined, and the refining of materials is a great knowledge. The melting point of each material is different, and the refining technique required is also different. If you want to be familiar with the refining techniques of various materials, you must practice constantly, and you need a lot of materials to practice. Once you make a mistake, the material will be scrapped.

In this way, the resources needed to invest in the initial stage of refining are a bottomless pit.

Not to mention that after getting started, you need to contact higher-level materials, learn more refining techniques and inscription engraving, etc. These all require a lot of practice to master, so without the support of a big force behind you, it is completely a fantasy for ordinary people to become a master of refining, no matter how talented you are.

After figuring this out, Wei Hong was not discouraged at all.

Because he had vitality points, as long as he had enough vitality points, he could automatically save dozens or hundreds of years of effort, which was the confidence for him to learn refining.

"Now the threat from the Cao family should not appear for the time being. I will try to go out hunting after a while, otherwise the vitality points will be in short supply again!"

Wei Hong thought about it for a while and made a decision.

Now that he has learned another skill, the vitality points that were not abundant to begin with have become even tighter. Since the Cao family is no longer watching him, he should go out and move around.

But these are just trivial matters for the time being and are not important.

For Wei Hong now, breaking through the bottleneck is the most important thing.

"Since the Baizhuan Shuihuan Dan is already in hand, I should also prepare for some breakthrough matters!"

When Wei Hong thought about his breakthrough, he couldn't help but feel a little excited.

But he immediately suppressed the excitement in his heart and made his mood calm again.

One day later.

In the secret room, Wei Hong sat cross-legged on a golden silk cushion.

On the wooden table next to him, a faint smoke was rising from an incense burner and slowly spreading to the surroundings, filling the entire secret room with a faint fragrance.

Wei Hong's eyes were closed at this time, and the whole person was like an ancient well, deep and calm. He had maintained this state for a day and a night, in order to adjust his body and mind to the best state.

In front of him was an ice jade box, and the box contained the Baizhuan Shuihuan Dan.

Today is the day for him to break through the bottleneck!

After a while, Wei Hong slowly opened his eyes.

He did not say anything, but opened the ice jade box with a solemn expression, then picked up the Baizhuan Shuihuan Dan directly, raised his head and swallowed it directly.

After the Baizhuan Shuihuan Dan entered his throat, it instantly turned into a warm current and flowed directly into his dantian.

Wei Hong then immediately closed his eyes again and began to practice the [Green Light Sword Technique] with all his strength.

Now he has already practiced the first level of the Green Light Sword Technique to the peak. If he breaks through, he will reach the middle stage of the foundation building stage. What he needs to do now is to break through the bottleneck of this level of practice.

Wow!

The spiritual power quickly circulated in Wei Hong's body, just like the sound of water flowing.

After the warm current transformed by the elixir entered the dantian, it immediately merged into the spiritual power and continued to circulate in the meridians with the spiritual power. Every time it circulated, the spiritual power would increase by one point.

At the same time, when Wei Hong began to run the technique with all his strength, the spiritual energy of heaven and earth in the secret room began to surge, and then formed a ten-foot-wide spiritual energy storm that directly wrapped him in it. A large amount of spiritual energy from heaven and earth also rushed into Wei Hong's body and was constantly absorbed and refined by him.

Since it is to break through the bottleneck, it naturally requires a large amount of spiritual energy as support.

At this moment, Wei Hong is like a bottomless pit. No matter how much spiritual energy he absorbs, he can't fill his dantian. The spiritual power that is constantly running is not only getting faster and faster, but also slowly starting to grow stronger under the dual blessing of the elixir and the external spiritual energy.

Wei Hong's eyes are closed, but the aura on his body begins to slowly increase, and exudes a trace of indescribable sharp sword intent. There is also a faint green light flashing on his body. As the aura increases, the layer of green light is also slowly becoming thicker.

Wei Hong naturally doesn't pay attention to the outside world. At this time, all his mind is immersed in running the technique.

Originally, he tried three times before, but he failed to break through three times.

Now with the addition of Baizhuan Shuihuan Dan, Wei Hong immediately noticed the difference.

In the past, no matter how many pills he swallowed or how much spiritual energy he absorbed, the bottleneck did not loosen at all when he tried to break through, and the skills could not be improved.

However, when he practiced the skills at this time, Wei Hong felt that the bottleneck was slowly loosening!
