About twenty minutes later.

Shen Feng let out a breath from his mouth and took back the power of the divine soul.

After the penetration of the power of the divine soul to the extreme, he still couldn't feel the special nature of the Phantom Thunder Rod.

However, he vaguely judged that there seemed to be some kind of restriction inside this phantom thunder rod.

This restriction must be broken before this magic rod can play its true role.

Shen Feng looked at the statue of a middle-aged man in the second layer of space, a wisp of divine soul in this statue at the beginning, after coming out to meet him, he returned to the statue, and there was no reaction so far, and the wisp of divine soul seemed to have entered a deep sleep.

This blood-red ring was created by this middle-aged man, and now because of the blood-red ring, he has found this magic lightning rod.

Therefore, Shen Feng faintly guessed in his heart, is this phantom thunder rod also related to this middle-aged man?

A moment later.

He didn't want to dwell on it any longer, and an idea popped into his head.

Subsequently, Shen Feng's divine soul power sensed the first layer of the blood-red ring, and after killing the Demon Slayer Saint Son and others in the Heavenly Desolate Realm, he put the corpses of these people into the first layer.

But now, there are no corpses of the Demon Slayer Saint Son and others in the first layer, only the soul rings on their fingers are left.

Seeing this, Shen Feng frowned, and when he first stepped on the Netherworld, he released layers of strong wind from the blood-red ring, which blew away the black flames on the Netherworld.

Could it be that at that time, the blood-red ring devoured the corpses of the Demon Slayer Saint Son and the others, and only then did it release that layer of mysterious and powerful wind?

Shen Feng felt that his guess should be very accurate.

His fingers moved slightly, and the soul rings that stayed in the first layer were all suspended in front of him.

Each soul ring is filled with a lot of high-grade dark stones, as well as spiritual liquids of various effects.

However, Shen Feng was not interested in these spiritual liquids at all, after all, the spiritual liquids he refined were many times better than these spiritual liquids!

Shen Feng took out a part of the Xuanshi, and then let the Phantom Thunder Rods appear again.

He wanted to set up a gravitational field here.

In his opinion, as long as the Phantom Lightning Rods absorb less energy, the surrounding gravity will not become extremely terrifying.

Shen Feng wanted to cultivate in a certain amount of gravity, so that in addition to increasing his speed, he could also enhance his physical strength.

He had already decided that as soon as he stepped into the first layer of the Heavenly Xuan Realm, he would embark on the path of awakening the Holy Body.

Time is in a hurry.

For the next few days, he continued to experiment repeatedly with the stone.

In the end, Shen Feng came to the conclusion that allowing the Phantom Thunder Rods to absorb a thousand high-grade Xuanshi at a time would be able to increase gravity by about five times.

And because the space on the second layer of the blood-red ring was limited, after absorbing a thousand high-grade Mystery Stones, the Phantom Thunder Rods were able to maintain the gravity here for about four days.

Increases gravity by a factor of five.

Shen Feng's speed here naturally slowed down a lot, and there was always a strong force on his body.

Of course, with a little more gravity, he can withstand it, but he can't be too eager.

At present, it seems that increasing gravity by five times is just right for him now.

Now.

Under a five-fold increase in gravity.

Shen Feng's walking speed here was obviously relatively slow, he took out one jar after another, and kept pouring the inferior holy liquid into his mouth.

In this environment.

If you take the lower grade holy liquid, then it is simply a matter of killing two birds with one stone, and it can make the physical body rise even more rapidly.

Of course, every time after drinking a jar of lower-grade holy liquid, Shen Feng would cultivate the six-rank body method type combat technique Fire Spirit Step here.

Although the Fire Spirit Step had already reached the Divine Movement level, he felt that in this environment, he could still slowly hone the speed of the Fire Spirit Step.

This Fire Spirit Step was the battle skill he had obtained from the Ancient World Map.

Under such a gravity field, Shen Feng used the Fire Spirit Step again and again, and the Xuan Qi in his body was rapidly consumed, which would soon make him sweat like rain.

Moreover, in the process of casting the Fire Spirit Step, the effect of the lower grade holy liquid will be integrated into his flesh and blood faster.

Once in the Immortal Realm, there was also a similar gravity room that could be used for cultivation.

However, the original gravity of the Heavenly Domain and the Immortal Realm is different, and the two worlds are completely incomparable.

After all, the strongest Immortal Emperor in the Immortal Realm, after coming to the First Heaven, can only be regarded as a cultivator at the lowest level.

Besides, under normal circumstances, the gravity chamber created has a gravity limit, and after a certain level, the gravity will not be able to rise.

And the energy consumed by the gravity chamber is huge.

As for the Phantom Lightning Rod, as long as it is given enough energy, it will be able to increase its gravity constantly.

Besides, it seems that the Phantom Thunder Rod does not consume too many dark stones.

Of course, as the gravity continues to increase in the future, the amount of dark stones consumed each time will become more and more, but it must be much better than the gravity chamber, and the phantom lightning rod can also be carried around.

In cultivation, life always passes very quickly.

In the blink of an eye, Shen Feng had been staying in the blood-red ring for two months.

At the end of the first month, Shen Feng had increased gravity tenfold.

Right now, Shen Feng had almost adapted to ten times the gravity here, and the clothes on his upper body had already taken off, exuding a kind of flesh and blood power all over his body.

After two months of extreme cultivation, combined with the consumption of the lower grade holy liquid, his physical strength has been greatly improved.

His strength has definitely increased by between three and four times on the original basis.

At this moment, Shen Feng once again unleashed the Fire Spirit Step, and the charm that overflowed from his body seemed to have turned into substance.

A terrifying fire flickered around him.

The two flames of the fierce tiger phantom condensed in the space behind him.

Immediately after, in the next moment, Shen Feng's figure suddenly disappeared in place, and kept appearing in all corners of the second layer of space, making it impossible for people to react at all.

That's still under a tenfold increase in gravity.

If it is said that under normal gravity, the speed at which he can burst out is definitely much faster!

The most important thing is that he once used the Fire Spirit Step to achieve the transformation of combat skills, but behind him was only a fierce tiger phantom, but now it has formed two heads.

Right now, Shen Feng could be sure that he had increased the power of the Fire Spirit Step a lot, and even the Fire Spirit Step had gone beyond the ordinary realm of divine movement.

He was very satisfied with his own progress, and it didn't take long for the energy in the Phantom Lightning Rod's energy to be consumed, and the surroundings gradually returned to normal.

Shen Feng suddenly felt as light as a swallow, and even between casual movements, his whole body was fluttering, like a piece of paper, which would float up at any time.

After another day of acclimatization to normal gravity, he left the second floor of the blood-red ring and returned to his room.

Stayed inside the blood-red ring for about two months, and outside for almost the past two days.

According to the speed of this flying magic weapon, it should also be about to reach the Ten Thousand Demon Sect.
