After passing through the small door, there is a corridor ten meters long, at the end of the corridor is a gate, outside the gate sits a person guarding here, this person is not very old, in his thirties, but his cultivation is very amazing, he is already a one-star fighting warrior.

The secret room cultivation is most afraid of being disturbed, so a one-star warrior is arranged to guard the gate here.

Gao Feng walked up to the one-star warrior and showed his number plate, the soldier nodded slightly, and gently pressed a button beside him, and the door next to him immediately opened, Gao Feng thanked him and walked into the gate.

Behind the door, there is another corridor, but at both ends of this corridor there are secret rooms, each secret room has a number on the door, and the number in Gao Feng's hand is 117, and Gao Feng went along the corridor and found room 117.

On the door of the room, there was a palm-sized white crystal, and the number plate was shaken on the white crystal, and the heavy metal door opened automatically.

Gao Feng approached the room, there was a bang behind him, the door had been closed on his own initiative, and at this time, except for the number plate in Gao Feng's hand and another number plate backed up by the academy, there was no way to open the door.

This is also to ensure that you will not be disturbed by outsiders when you cultivate in the secret room.

The door was closed, and Gao Feng looked into the room, the whole room was about fifty square meters, without any decoration, the walls and floors were all bare, only a few bright magic lamps hung on the ceiling to illuminate the room.

In front of the room, near the wall, there is a two-meter-high blue-black boulder, this blue-black boulder is extraordinary, it looks like a stone, in fact, it is a synthetic crystal, not only strong and abnormal, with a special magic array, it can also play a role in absorbing attacks, any attack that falls on this blue-black boulder will be easily sucked away.

This blue-black boulder can be used as a target for skill release.

At a glance in the room, there was nothing else in the room except for this blue-black boulder that was the target.

So what is the significance of this secret cultivation room?

Gao Feng doesn't know what it means, but it doesn't matter, just give it a try.

Approaching the blue and black boulder, Gao Feng stretched out his hand to the boulder, and the magic power in his body surged, and immediately a flame erupted from Gao Feng's hand and sprayed towards the blue and black boulder in front of him.

As soon as the flames came out, Gao Feng's face changed slightly, and the power of this flame was only one-third of the usual.

The peak continued to spew flames, all of which were spewing out a third of what they normally would.

Gao Feng suddenly understood that there was a strange power in the secret law cultivation room, which could suppress the release of magic, so that the magic cast was only one-third of the usual.

And this strange phenomenon can help people to better cultivate magic.

This is like running with weights, running in a weight-bearing state is naturally more tiring and harder, but it is also more effective, once the weight-bearing is removed, then the effect of cultivation will also burst out in an instant.

This is the significance of the Secret Law Cultivation Room.

"Understood, I see. ”

Gao Feng laughed heartily, and the flames in his hands continued to erupt.

With the flame jet, the flame runes in the source of magic power are also constantly flickering, constantly accumulating a strange power, and when this power accumulates enough, it can be advanced to the Ten Rank Ultimate Great Perfection Realm.

For this cultivation, Gao Feng had already prepared sufficiently, and the water and food had been placed in the Void Realm and could be accessed at any time.

In this way, when I was thirsty to drink water, I was hungry to eat, and I didn't know how long it was, the source of magic power suddenly shook, and the rune of the ignition technique was changed, the rune became three points larger, and the nine auras that surrounded it became one, combined into one aura, and the entire rune emitted endless light, like a star.

At this point, the ignition technique has advanced from the nine-rank Great Perfection realm to the ten-rank ultimate Great Perfection realm.

Gao Feng exhaled tiredly, Okay, the ignition technique has advanced to the tenth grade, and the means of fighting are finally there.

Advancing to the tenth grade, you will have the power of divine power, and the power will be greatly increased, even if it is an entry magic like ignition, it will also have a strong killing effect, which is the source of confidence in the peak victory.

The magic was successfully promoted, but Gao Feng was also tired enough, and he was too lazy to move when he spread it on the ground.

The secret method cultivation room is really extraordinary, and it is very beneficial for the cultivation of skills, if it were not for the special effect of the secret method cultivation room, if the ignition technique wants to be cultivated to the tenth grade, I am afraid it will take more time.

It was also at this time that Gao Feng discovered that the significance of the secret method cultivation room is not just as simple as "increasing the weight", but with the help of the effect of "increasing the weight", people can better understand the true meaning of the skill when cultivating the skill, comprehend the skill, and achieve the purpose of improving the skill level.

The normal cultivation method should be in the secret method cultivation room, while cultivating skills, and at the same time comprehending skills, this is the correct way to cultivate.

However, Gao Feng was not optimistic about his own understanding, so he did not perceive it, but used a simple and crude cultivation method and cast a large amount of magic to achieve the purpose of making up for his clumsiness.

Gao Feng lay on the ground for a short while, his body gradually recovered, and after eating a little food and water, he stood up.

When the ignition technique finally reached the tenth grade, I don't know what kind of power it is after the tenth grade, and whether it can bring victory to itself.

As soon as Gao Feng raised his hand, a flame erupted from the palm of his hand, this flame was one meter in diameter, orange in color, but with gold wires, the flame fell on the blue and black boulder, and immediately burned a scorched black patch on the blue and black boulder.

The huge blue-black rock seemed to make a clicking sound.

Gao Feng was startled and hurriedly stopped casting.

This blue and black boulder is the property of the academy, and if it is really burned out, I am afraid it will be another annoyance.

After Gao Feng put away the flames, he hurriedly ran to the boulder to check, and as soon as he got close to the boulder, a heat wave rushed towards him, which showed that the temperature of the boulder was very high.

Gao Feng looked towards the boulder, and the huge blue-black boulder had been burned by the flames with a large area of charred black, and on the blackened stone face, small spots and cracks were faintly visible.

Gao Feng's eyes suddenly widened.

The power of this flame is too strong, the material of this boulder is very strong, the fire resistance is also extremely strong, plus the ability to absorb magic, it is a one-star magic, and it is difficult to destroy it.

And now, Gao Feng's ignition technique has caused damage to the boulder, so Gao Feng's ignition technique will at least not be worse than one-star magic.

The ignition technique of the previous nine grades had no effect on the boulder even after burning for a long time, while the ignition technique of the tenth grade burned scorch marks on the boulder with just one spray, and the difference in power between the two can be said to be clear at a glance.

This is also the terrifying thing about the Ten Rank Spell.
