In Lu Tong's perception, after the two murderous qi soldiers were scattered, there were two streams of energy that poured into his body.

This is a transcendent energy, and it does not need to be guided, and it can enter the body of the martial artist in a directional manner.

If you are in the interval period of qi and blood improvement, the influx of these extraordinary energies will inevitably help people accelerate the increase of qi and blood volume.

It's a pity that Lu Tong is now at the peak of the Four Realms, and his qi and blood values have temporarily reached a bottleneck, and he can't break and absorb them.

But he didn't care about these transcendent energies, but another intangible thing within them.

"It's murderous!"

The reason why Lu Tong looked uncomfortable and struggling was also because of that murderous aura.

The murderous aura is formless and qualitative, but it is real here, and in Lu Tong's understanding, it is a killing trend.

And this influx of murderous aura can not only make him feel the existence of the potential more clearly, but also go straight to his mind, making his spirit affected and impacted.

Lu Tong's feelings were like two soldiers shouting and killing in his mind, and even wanted to guide and control him to kill.

If it is a person with a slightly weaker mental will, if he is hit by this murderous aura, I am afraid that he will soon lose his consciousness and turn into a machine that only knows how to kill.

And Lu Tong and them, the martial artists of at least the four realms, naturally have a different spiritual will from ordinary people, and they can resist the influence of murderous energy.

"In the process of tug-of-war with the influence of murderous energy, it is to condense the spirit." Lu Tong said secretly, this is his experience, and it is very obvious.

As for the effect of refining the body, it was also very significant, because the influx of those extraordinary energies would drive the qi and blood in his body to run and purify at a high speed, and then repeatedly refine the inside and outside of the body.

Even if these transcendent energies are just going through the motions in the body, they can be tempered from the inside out and directly improve his physique.

"That's a good thing!"

Even though Lu Tong was experiencing the impact of murderous energy on his spirit, he still couldn't help but like this feeling, it was so wonderful.

Pain and happiness, probably talking about how he feels now.

After digesting it in place for a quarter of an hour or so, Lu Tong felt the disappearance of that impact and the passage of extraordinary energy.

However, those supernatural energies did not dissipate, but gradually converged into the palm of his hand, eventually forming a fist-sized crystal.

"Transcendent Crystal!" Lu Tong was happy in his heart, this was an additional gain after breaking up the killing and gasification soldiers.

Gao Yunjing had also mentioned to Lu Tong before that the extraordinary energy in the Murderous Qi Transformation Soldier would not dissipate, but would converge into a Transcendent Energy Crystal because of the loss of the support of the Murderous Qi.

These transcendent energy crystals are not reserved for them as students.

All the transcendent energy crystals obtained in the ruins of the ancient battlefield must eventually be returned to the military.

Correspondingly, the military will give a certain amount of military merit in return according to the proportion.

For example, this fist-sized transcendent energy crystal has a market value of one million Xia coins, and the conversion of military merits should be about 10,000.

However, the military can only give military merit rewards of about 1,000, which can be regarded as 'labor expenses' for students, or subsidies.

After all, even without this fee, the cadets would rush to come to the battlefield ruins, so it is not too much to subsidize it.

For those students with strong resources behind them, what they value is, of course, the murderous refining effect, and they don't look down on this funding at all.

But Lu Tong doesn't think so, these military exploits are definitely more and more for him.

"Feel it?" Gao Yunjing has been paying attention to the movements of the landing pass nearby.

Seeing that he had regained his composure, Fang Cai stepped forward and said, "The murderous aura here can not only concentrate the mind, but also refine the body. ”

"Concentrating on the mind can make your spirit more stable, pure, and vigorous, and refining the body is also a key help for you."

"When I came in last year, I was also at the peak of the Four Realms, and it was here that I found the opportunity to break through to the Five Realms."

Lu Tong nodded, and couldn't help but admire: "This is really a rare treasure." ”

Not to mention the benefits of murderous energy to individuals, just the continuous accumulation of extraordinary energy can be said to be invaluable.

In other words, this is a large mine that can continuously produce energy crystals.

The murderous qi turned the transcendent energy that was free between heaven and earth into weapons, and then they were precipitated into transcendent energy crystals and supplied to the military.

For the military, this is tantamount to an important strategic location.

As for what Gao Yunjing said, which would help him break through the Five Realms, Lu Tong also thought so.

Because from the peak of the four realms to the five realms, what is needed is no longer just the mastery of strength, but after the five internal organs and six internal organs are refined, the body is tempered as a whole again, and finally the internal and external resonance and self-generation of the qi are achieved.

This is the key to breaking through the fifth realm.

Only by completely opening up the skin, flesh, and bones that have been quenched before, plus the internal organs, into a cohesive whole, can resonate and give birth to true qi and blood.

And the transcendent energy that entered the body just now can obviously speed up this process.

"In fifteen days, I will definitely be able to break through the Five Realms." Lu Tong was full of energy, and his eyes were shining when he looked at those murderous soldiers.

It's definitely not because of the extraordinary energy crystal, it's just that I want to break through.

"Don't overdo it, once you go mad, you have to find someone to rescue you, and you can't come in again."

It seemed that seeing Lu Tong's ambition, Gao Yunjing reminded in time.

The students who entered here were at least two people traveling together, also to avoid this from happening.

Once a student is controlled by murderous energy and goes mad, at least someone around him can call for help for him.

"Understood, senior sister, I'll be careful." Lu Tong calmed down, in such a good place, he couldn't give up halfway.

Seeing that Lu Tong listened, Gao Yunjing didn't say anything more, and began to hunt those murderous soldiers nearby.

And after Lu Tong felt that he had regained his calm, he no longer hesitated and killed the past.

From more than three o'clock in the afternoon until the sun set, Lu Tong fought against those murderous soldiers for nearly three hours, with almost no rest in between.

The Transcendent Energy Crystals accumulated in his hands already had eleven of them.

Gao Yunjing, who was beside him, reminded him several times, for fear that Lu Tong would really be controlled by murderous aura and go mad.

Because she is also hunting and killing gasification soldiers, but the efficiency is less than half that of Lu Tong.

The main thing is that every time she fights against the influence of those murderous aura, she lasts twice as long as Lu Tong, and then she has to rest and calm down before she can continue.

But Gao Yunjing soon found that Lu Tong's efficiency was still like no one, and it didn't seem to have any effect.

This simply subverted her cognition, because as far as she knew, even Sikong Lieyun was not so efficient.

"Could it be that the spirit of the junior brother is different from ordinary people? His sword momentum doesn't stop at the first heaven? Gao Yunjing said strangely.

Except for Luo Bing, no one knows what level Lu Tong's current sword strength has reached.
