After staring at this sword for a long time, Lin Sen's eyes flashed, and his expression showed decisiveness. I saw that he threw his right hand and pinched it with both hands, and a golden light shot out from outside his body, and immediately spread a strong coercion around the room, forming a wall of coercion, surrounding the entire room, making it impossible for outsiders to investigate with divine sense, and even unable to approach this room.

"Hide!"

Lin Sen snorted lightly, pointed his finger, and immediately countless smoke clouds dispersed, instantly filling the entire room, and then dissipating.

After doing this, Lin Sen was relieved, he looked at the sword, and grabbed it with his right hand. The moment he grabbed this sword with his right hand, the extremely cold aura inside it immediately rushed into Lin Sen's body, causing frost to appear in his right hand instantly, spreading rapidly at an extremely fast speed.

Lin Sen's expression changed in an instant, he pinched the trick with his left hand, and immediately pointed it towards his right hand, and an extremely strong spiritual power rushed towards his right hand, making the stiff muscles of his right hand bloody again, and he let go of the sword in his hand.

"It's so cold, maybe it can't be called cold, but yin. "Yin Qi is the Yuan Yin of sex, and Yin contains the intention of death. This is clearly a flying sword that is sacrificed in the extreme place of yin death, and the place of extreme yin death is divided into four types, namely yang yin, cold yin, earth yin, and heavenly yin.

The land of yang and yin is relatively simple, and the place where a large number of living beings die is yang and yin, and the more people die, the heavier the yin qi in the land of yang and yin.

There are some difficulties in cold and shady places, and most of them can only occur in extremely cold places.

The earth yin is more difficult, it is a great chance to encounter, the so-called earth yin is the breath that can only appear from the abyss of the earth.

As for the heavenly yin, it will basically not appear, because in order to form the heavenly yin land, it is necessary to combine the above three yin qi to have a wonderful mutation, and the yin qi produced by this change can be called the heavenly yin.

"The cold of this sword is very likely to be cold yin!" Lin Sen's eyes were blazing, and with Feng Chenzi's understanding of yin qi, he immediately saw that this sword was extraordinary.

At this time, Lin Sen snorted coldly, slapped the ground fiercely, and the sword immediately bounced up, only to see Lin Sen's right hand pinching a finger, and a cold light rushed out from the flying sword, the sword body was snow-white, and the cold air was in stark contrast to the black gas of the scabbard.

The moment the sword flew out, it seemed to regain its vitality, and immediately it buzzed, and it was about to rush out of the room as if it had a spirit.

As soon as he rushed halfway, the flying sword seemed to hit an invisible wall, quickly turned back and rushed to other places, after being blocked by the invisible wall several times in a row, the sound of the flying sword buzzing was great, and the cold light of the sword tip flashed, and it rushed directly towards Lin Sen.

Lin Sen's expression was as usual, and without hurrying, he shot out a golden light and flew towards the sword. The flying sword seemed to be extremely frightened of this golden light, and retreated again and again.

Lin Sen smiled coldly, with a move of his right hand, the golden light no longer pursued, but hovered around Lin Sen's body, the flying sword did not dare to move forward, but turned around and continued to hit around, as if he was about to rush out of the room.

Fortunately, Lin Sen had prepared and sealed off the room, otherwise once this sword flew out, the consequences would be unimaginable.

"This sword is so afraid of the coercion in the Nine Illusions Tower, maybe it can deter this sword. Lin Sen muttered in his mouth, and his hands once again shot out a stream of golden light, forming a fine net to catch the sword.

At this time, the sound of the flying sword humming continued, and it rushed left and right, but it couldn't rush out. At this time, the light on its sword dimmed a lot, and even the humming sound became weak.

Lin Sen didn't say a word, his right hand flipped again, and the palm-sized Nine Illusion Pagoda appeared instantly, and when he appeared, Lin Sen immediately threw it, and the Nine Illusion Pagoda immediately became larger, and its height reached the roof. In the process of its fall, this sword is encased in it.

Lin Sen looked at the flying sword of the tower body that was constantly hitting inside, his eyes flashed, and he seemed to have an understanding.

"The more spiritual the magic weapon, the more difficult it is to sacrifice, and even if its owner dies, it takes a lot of energy to refine it into its own thing. ”

Lin Sen narrowed his eyes, it was the first time he had seen such a spiritual flying sword, and at this moment, his heart to refine this treasure was particularly strong.

As time passed, the struggling movements of the flying sword in the pagoda not only did not ease, but became more and more intense, and the sound of thumping kept sounding, but it was impossible to break the pagoda.

Lin Sen snorted coldly, opened his mouth and spit out a mouthful of spiritual power, which then merged into the tower body and appeared in the place of the flying sword, and the flying sword was immediately wrapped in the energy of spiritual power when he couldn't dodge.

At this moment, the struggle of the flying sword immediately became crazy, which made Lin Sen can't help but tremble. Lin Sen gritted his teeth, once again spit out a mouthful of spiritual power to wrap it, and under the pinching of his fingers, he brought this sword into the higher part of the Nine Illusion Tower, because the higher he went, the stronger the pressure.

It wasn't until it was brought into the eighth floor of the Nine Illusion Tower, when the flying sword reached the one hundred and eleventh ladder, where the breath of the ancestor of the Hidden Void Peak was held, the flying sword immediately trembled violently, and it seemed to be extremely frightened, and soon stopped struggling, but gradually calmed down in trembling.

The time of the night passed quietly, and the flying sword was spent in peace, Lin Sen's face was pale at this moment, this night, he had already spit out dozens of mouthfuls of spiritual power, even if he was equivalent to the cultivation of the middle stage of foundation building, plus the help of the Nine Illusion Tower, he had reached such a level in such a short time.

The early morning sunlight penetrated through the window, Lin Sen's sacrifice continued, although the flying sword was no longer struggling, but this did not mean that the sacrifice had been successful, Lin Sen did not take it out easily, because it is very likely that once it is taken out, there will be a phenomenon of backlash, and in the end, not only will it fall short, but it may also be killed.

Such a spiritual thing often appears to "cheat death" to deceive the priest, which Lin Sen still understands.

"This sword is from the hand of Li Ruhai, and this sword is so afraid of the coercion of the ancestor of the Hidden Void Peak, what is the connection between this? Li Ruhai is the elder of the Hidden Void Peak, this person is not right, he has been peeking at the Nine Illusions Tower for a long time, could it be that this sword was stolen by him, maybe this sword is related to the ancestor of the Hidden Void Peak" Lin Sen kept thinking in his heart, and at this moment, Lin Sen's expression suddenly moved. Soon, the voice of the ancient wind came from outside.

"Uncle Shi, do you want to go out with me today to see Uncle Axe's appliance shop?"

Lin Sen took a deep breath and replied, "Gu Feng, my cultivation is at a critical juncture, you can go first." ”

Gu Feng stood outside the door, feeling the coercion emanating from Lin Sen's room, and no longer spoke, but sat cross-legged outside Lin Sen's door to protect his Dharma.

Gu Feng's actions, Lin Sen saw in his eyes, and he was sincerely grateful for Gu Feng's loyalty. Gu Feng was able to let go of his arrogance and follow Lin Sen, which already required great courage, and it was difficult for anyone to do this. Who would be willing to let go of the star-studded sky and be willing to be someone else's slave!

But Gu Feng was able to do this, in order to be able to gain enlightenment by Lin Sen's side, he did not hesitate to disobey Feng Songzi's advice and resolutely follow Lin Sen. It can be seen that the ancient style is extraordinary, and it is worthy of being a proud person!

Lin Sen no longer paid attention to the ancient style and continued to practice, and time passed little by little, and night fell again. He had already absorbed three medium-grade spirit stones to provide enough spiritual power, but the flying sword still hadn't finished cultivating.
