A message coming out of the Dark Rune was a cultivation technique—the Dark Stealth Technique. This is a very special exercise, the higher the strength, the stronger the power of the stealth technique. Wherever there is darkness, it can become a hiding place for the caster, the shadow of people, the shadow of trees, the shadow of the mountain, etc

This Dark Stealth Technique is exactly the opposite of the Light Stealth Technique that Fang Rou cultivated. The invisibility of light can be performed wherever there is light, moonlight, sunlight, fluorescent, candlelight, and so on. Lin Feng had a trace of dark power in his hands, and he was somewhat handy when he cultivated the Dark Stealth Technique.

One day, two days... Seven days have passed, and there has been a sudden fluctuation of aura in the cave, in the deep cultivation

Ziyi and Fang Rou came to their senses, and they both looked towards the place where the aura fluctuated violently.

It was Lin Feng's cultivation place, and at this time, Lin Feng's figure had become nothing, and a dark aura enveloped his body, and the whole person seemed to be hiding in the darkness, and even the aura on his body became weaker and weaker.

"This is the Dark Stealth Technique!" Fang Rou, who had cultivated the Light Stealth Technique, recognized at a glance what the situation in front of him was.

Where there is darkness is the world of the Dark Stealth Technique, Fang Rou popped out a mana towards the entrance of the cave, shattering the gravel at the entrance of the cave, and constantly falling and gathering to the entrance of the cave, the light from the outside world was gradually blocked, and a shadow was cast onto Lin Feng's position.

Lin Feng seemed to sense Fang Rou's movements, and pinched out a wonderful magic seal with both hands, and the aura around him shook violently and became calm, and his whole person had disappeared from the spot. What Zi Yi and Fang Rou saw with their naked eyes was only the shadow cast. The soul power of the two of them also continued to sweep around in place, but they didn't feel any breath at all, and only then did they become convinced that this Senior Brother Lin Feng had only spent seven days cultivating the Dark Stealth Technique, which was the primary condition skill for becoming a Dark Assassin.

Fang Rou's eyes were full of smiles and shock. At the beginning, it took her three years to cultivate the Stealth Technique of Light, but she didn't expect that this Lin Feng would succeed in only seven days, but she didn't know how long his Stealth Technique of Darkness would last.

As soon as this idea appeared, he saw Lin Feng's figure manifesting from nothingness, and his whole face was a little haggard.

"The dark power is still too weak, and the demand for dark power is too high for this dark invisibility technique. With my current strength, I can support a maximum of twenty breaths, and that is already the end of my power. Lin Feng smiled bitterly a few times, although he didn't last so long the first time, he was happy.

"Congratulations, Senior Brother, you have met the basic requirements to become a Dark Assassin. If there is wine, we should come and have a few drinks and celebrate. Fang Rou's proposal made Lin Feng's heart move, and he remembered that there was also a small pot of fruit wine in his bracelet, which was given by the scholar, and he had kept it by his side but forgot it. If it weren't for Fang Rou mentioning wine, I don't know how long it will be stored.

"I don't have good wine, but I do have a little fruit wine. Lin Feng's wrist flashed, and a strange-shaped wine jug appeared in his hand. He pulled the cork and sniffled, his brow furrowed immediately, and he couldn't smell a trace of wine.

After taking a closer look, I found that there was indeed a pot of liquid in the flask, but it was a very transparent and pure liquid, and there was no color and aroma of fruit wine at all.

"Could it be that the scholar is fooling me?" Lin Feng took a sip in disbelief, and the liquid did not have the slightest taste in his mouth, as if he hadn't drunk it.

Smacking his lips, Lin Feng smiled a little embarrassedly, and after covering the wine jug, he withdrew the bracelet, "Mistaken, I thought... ”

Before he finished speaking, his face immediately changed, and powerful flames rose from his belly. This sudden burst of fire soon formed into fire dragons, flowing unscrupulously throughout the body. A vast and terrifying mana emanated from him, and Ziyi and Fang Rou hurriedly exited the cave in shock.

This mana was too powerful, and the cave Lin Feng was in couldn't resist the impact of this force, and it soon collapsed and collapsed, causing a violent vibration of the small peak.

"What's going on? How can this be, that mana just now is so terrifying. Ziyi felt the ground shake and the mountains shook, and couldn't help but fly into the air, looking at the small mountain peaks that kept breaking and collapsing with a shocked face.

Lin Feng felt as if he was about to explode, the power of the fire dragon in his body became more and more fierce, and in a hurry, he hurriedly ran the Void Pill in the Seven Great Dantians, and suddenly seven fire dragons pounced into the Dantian. Entering the mysterious dantian space, Lin Feng discovered what kind of fire dragon this was, and it was clearly the Seven Rainbows. However, because the power emitted by it is so large and majestic, it feels like it is burning.

The seven Changhongs melted into the Void Pill, and suddenly transformed into a thick and endless mana, and the Void Pill continued to condense and become powerful under the supplement of this power.

"What kind of wine is this? It has such power, what is the origin of that scholar, not only can he educate low-level fierce beasts, but also create such strange things. Lin Feng knew that this Changhong, if it was to be transformed into a top-grade Essence Soul Pill, it might need to take a hundred pills in a row. Seven Changhong is equivalent to seven hundred high-grade spirit pills.

This is not the final data, because in the turn of the Void Pill, the three breaths will swallow and absorb the seven great rainbows. The remaining power in the body found an outlet again, and drilled into it wave after wave.

"It's not good, the power contained in this sip of wine is too strong, and the power in the body is too strong, and the horror will explode if it continues like this. Although Lin Feng was constantly running the Void Pill, the speed of devouring still couldn't keep up with the power derived from his body.

"Boom... "At this time, a Changhong broke through a barrier and actually rushed into the Purple Mansion space. The clones of the Resentful King, the Little Demon King, and the Pan who were meditating in the Purple Mansion space were all awakened.

The three thoughts in the purple mansion seemed to sense something and actually started working automatically, and Changhong was divided into three and merged into the three soul thoughts.

The powerful addition of this power added fuel to the fire of the three soul thoughts, and their strength increased rapidly.

"No, this power can be transformed into not only mana, but also soul power. Feeling the continuous improvement of the mana in the dantian, as well as the continuous growth of the power of the three soul thoughts, Lin Feng couldn't help but howl.

This wavelength howl lasted for more than ten breaths, and under the catharsis of internal and external forces, Lin Feng was finally able to control the only remaining power in his body.

The seven Void Pills in the dantian are already half-truthful, and the main idea in the Purple Mansion space also faintly has a soul fire, and it seems that as long as you increase your strength, you can successfully ignite the soul fire. This is an opportunity, and it is also an opportunity for strength to take off again.

After waiting for the last trace of strength in his body to be consumed, Lin Feng hurriedly took out the wine jug and took another half sip, which was about half of the first time.

Because of the experience, and the strength of the Void Pill and Soul Thoughts has grown to another level, it is much easier to consume this power.

The continuous growth of the strength on Lin Feng's body obviously failed to hide from the two women in mid-air, Lin Feng's own mana was about 300,000 combat power, and in just a short period of time, the mana had grown to about 450,000.

"Smack. Syllable... ”

Seven crisp sounds were heard in the dantian in a row, and seven golden Fadans were constantly rotating in the dantian space, exuding a spiritual aura. Seven Fadan, seven breaths connected together. The combat power of 450,000 soared again, directly increasing to about 500,000 before slowly subsided.

And the main soul thought in the purple mansion space also trembled violently, and a five-colored flame burst out from inside the soul thought, the five colors represent the power of the five elements, which can be regarded as the most mediocre soul thought, and it is countless levels lower than the water soul thought of the purple clothes.

The more singular the power attribute of the soul thought, the greater its future development potential.

Although it was a five-element attribute soul thought, Lin Feng was not much disappointed, he was a contented person, he already had two light and dark attribute soul thoughts, if he could refine that fire safely in the future, he might still be able to have a single-attribute soul thought, and at that time, he would have three single-attribute soul thoughts. Throughout the ages, I am afraid that there is not a single hand that can have this kind of talent.

"This soul power is so strong. "Lin Feng's main soul soul has become a soul fire, and his soul power has also soared. In addition, the power of light and dark soul thoughts has increased a lot, and the overall soul power can already extend to a range of one hundred and fifty miles.

This kind of soul power can only be possessed by the powerhouses in the early stage of the Evolution Realm, like the purple cloth soul power in the middle stage of the Divine Power Realm, which extends at most fifty or sixty miles. If you can be promoted to the peak of the Divine Power Realm, your soul power can break through the range of a hundred miles.
