After dealing with Wei Jianqiang's affairs, Yu Ge felt that his thoughts were much more understandable.

In this way, he can finally practice with peace of mind.

Thinking of this, Yu Ge hurried back to the yard, rushed into the quiet room, took out the sword heart pill, threw one into his mouth, and entered deep cultivation.

Time passes quickly, and a month passes quietly.

On this day, Yu Ge woke up slowly from his cultivation state.

"There are only the last three pairs of small bones left to completely refine the skull. At that time, I completely entered the sixth level of foundation building."

Yu Ge was full of joy.

In the past month, the refining speed in the later stage may have been greatly improved because of the refining of many skulls.

Now, there are only three pairs of listening little bones left.

As long as Yu Ge refines the last three pairs of listening to Xiaogu, he will enter the sixth level of foundation building.

Thinking of this, Yu Ge felt endless energy all over his body.

"continue!"

Yu Ge swallowed a sword heart pill and a bone-transforming pill, and at the same time activated the secret technique of Sanyin bone forging, gathering all his spirits on the last three pairs of listening bones.

The small bones are composed of hammer bones, incus and stapes respectively.

The stapes and incense are relatively thin, so Yu Ge wants to start refining with the hammer.

Thinking of this, Yu Ge first focused on the hammer on the left ear.

The hammer bone is shaped like a drumstick, split head, shank, lateral protrusion and anterior protrusion.

Yu Ge looked at it and felt that he should start with the biggest head.

Thinking of this, Yu Ge injected a trace of sword energy, but who knew that at this moment, Yu Ge felt a roar in his mind, and his eyes became dark, and he fainted immediately.

I don’t know how long it took for Yu Ge to wake up slowly.

"Damn, what happened?"

Yu Ge suddenly sat up, but found that the mouth was salty and astringent. With a light touch, it turned out to be covered with blood. He was shocked at the time.

"It's over, my hammer!"

Yu Ge hurriedly entered the state of inner vision, and he felt relieved until he found that the hammer bone was not hurt.

"It seems that the sword energy is still too strong!"

Yu Ge soon thought of the problem.

Ting Xiaogu's fragility is not enough to withstand the ferocity of the sword energy. Even though his Ting Xiaogu has been strengthened by the Vajra power hundreds of times, he is still fragile.

Therefore, if you want to refine the listening little bones, you must use more gentle spiritual energy.

Before, Yu Ge used the fierce sword energy, and it was also the enhanced sword energy, so it caused the entire Tingxiaogu to shake, and finally shocked himself.

"When the effect of the sword heart pill disappears, try changing to the most gentle Vajra power first."

Soon Yu Ge had the next cultivation plan.

However, Yu Ge looked back and thought, it seemed that his current sword heart pill power was still there? If he did nothing, wouldn’t he waste the precious sword heart pill in vain?

"Since the medicinal power of Jianxin Dan is still there, why not comprehend the Lingyun sword energy first!"

When I saved Wei Jianqiang and He Anqin, the power of the sword energy as silk shocked He Anqin? It also made Yu Ge still remember it fresh.

Since Jianxin Dan can condense the sword energy into silk, taking advantage of the medicinal power of Jianxin Dan? Yu Ge wanted to see if he could find a way to continue to condense the sword energy into silk without Jianxin Dan.

"The sword energy is like silk mainly because of the high compression of the sword energy? But I use this highly compressed sword energy to refine the bones? Wouldn't it be a bit of putting the cart before the horse?"

Yu Ge fell into deep thought.

The main reason why sword energy is like silk is that it almost compresses the sword energy to the extreme, and this is the greatest function of sword heart pill.

Yu Ge had been using this highly compressed sword energy to refine the skull before. Now, when I think about it, it feels like a chewing peony.

If he had started studying Jianxindan early, perhaps his current sword energy would have naturally reached the realm of sword energy as silk.

Thinking of this, Yu Ge felt that he was still too impatient to practice recently.

"There are 3 sword heart pills left? If you can use these 3 sword heart pills to make my sword energy undergo a qualitative change? Even if you don't refine the skull, my strength will be increased by more than ten times."

Yu Ge's eyes were faint and shiny.

"But if you want to understand the process of sword energy compression, you must wait until the effect of this sword heart pill disappears, and then eat the sword heart pill and observe this process? Until you fully understand the process of sword energy compression."

Yu Ge frowned.

But if you really do that, the current sword heart pill will still be wasted.

Thinking of this, Yu Ge felt like he was in a stubborn position.

“What’s wrong?”

Yu Ge continued to think.

Suddenly, a blurred light flashed through Yu Ge's mind.

"It seems like I've thought of something?"

Yu Ge pinched his chin and pondered his head.

The colorless spiritual energy is converted into sword energy, and this transformation is called positive transformation.

And the transformation of sword energy into colorless spiritual energy is a reversal.

If the quality difference is not large? The colorless spiritual energy and the sword energy can be transformed freely.

But after taking the Sword Heart Pill, his sword energy will be compressed into silky sword energy. This sword energy is far higher than the colorless spiritual energy in terms of grade, so it cannot be directly converted into a higher-level colorless spiritual energy.

On the other hand, if you want to transform the sword energy like silk, you must have a higher level of colorless spiritual energy.

A higher-level colorless spiritual energy must not be condensed.

However, because the characteristics of the silky sword energy are far higher than those of the sword species, it can allow the silky sword energy to directly return to the sword species to improve the quality of the sword species.

As long as the quality of the sword seed is improved, the quality of the spirit seed will naturally be higher when converted back to the spirit seed.

When the quality of the spiritual seed is high, the colorless spiritual energy released will be high, and the colorless spiritual energy with high quality can be transformed into any kind of high-quality spiritual energy.

Thinking of this, Yu Ge suddenly felt that he had found a shortcut.

"Why don't you try?"

Yu Ge is not sure if this is OK.

After all, the previous experiments have basically failed.

If the positive and reverse transformation cannot be carried out at will, then in general, the colorless spiritual energy is still lacking now.

This is not the result Yu Ge wants to see.

"Try it!"

Thinking of his success and his combat power increased, Yu Ge couldn't help but absorbed a trace of sword energy back to the sword seed.

At that moment, Yu Ge's sword seed seemed to be thumping.

Then a rift appeared.

"Damn it, it's broken, it won't be so miserable!"

Yu Ge was so scared that he was speechless.

You should know that whether it is a spiritual species or a sword species, they are crystals with highly condensed spiritual energy.

Yu Ge has seven wheels, and his spiritual energy is far higher than that of ordinary foundation-building monks.

If the sword seed is accidentally destroyed, the violent spiritual energy will rage at that moment, that moment will be enough to break Yu Ge to pieces.

"What should I do? Print C? No, the repair effect of Print C is too slow."

Yu Ge racked his brains to think.

At this moment, a bold idea appeared in his mind.

"By the way, I still have the idea of ​​visualizing the Mingyue!"

Recently, Yu Ge has been refining his bones, and the sequelae of Mingyue's visualization has led to Yu Ge not daring to continue practicing Mingyue's visualization recently.

But at this time, Yu Ge could think of only the way to visualize Mingyue.
Chapter completed!
