In the dim cave, Yu Xiu opened his eyes, and his eyes were slightly excited.

"After these days of tempering, my Yin God has become much purer, and the next thing is to break through to the realm of day travel. ”

He sat cross-legged on the ground, silently thinking in his heart, with determination in his eyes, and took out three talismans from his sleeve.

These three talismans were all outlined with red yellow lines, and the slight heat in his hand was like a piece of burned iron, which was the fire talisman he had drawn with gunpowder.

According to the Three-Turn Fire Law.

The nine-grade gunpowder is inky black, with a metallic luster, and is black powder, and the fire talisman made of it is a black fire talisman; the eight-grade gunpowder is reddish-yellow, cinnabar-like, and is yellow gunpowder, and the fire talisman made of it is a yellow fire talisman; the seven-grade gunpowder is silver-colored, platinum-like, and is white gunpowder, and the fire talisman made is a white fire talisman.

The three fire talismans in Yu Xiu's hand were the eight-rank yellow fire talismans, and each one was more than three times as powerful as the nine-rank fire talismans.

He looked down at the three yellow fire talismans, and thought in his heart: "If the Nine Rank Black Fire Talisman is hit, it can burn a black flame and ignite a big tree in an instant." I don't know if this yellow fire talisman will burn out a red flame, and what level of specific power can it reach......"

Although the Fire Boy was able to refine eight-grade gunpowder, the success rate was very small, and the eight-grade gunpowder obtained could only be made into five yellow fire talismans.

Therefore, Yu Xiu had always used the black fire talisman to refine the Yin God before, and had never used yellow powder, let alone deliberately wasted a yellow fire talisman to test its killing power.

And now he is going to break through to the realm of the Solstice Journey, if he makes do with the use of the Black Fire Talisman, it is likely to lead to the failure of the breakthrough, and he can only take out the Yellow Fire Talisman.

Thinking of this, Yu Xiu sighed slightly in his heart: "If only the fire boy could refine seven grades of gunpowder." ”

Although the three Yellow Fire Talismans can also achieve the effect of the Seventh-Rank White Fire Talisman, the higher the quality of the Fire Talisman, the greater the quenching effect on the Yin God, the shorter the time, and the smaller the side effects.

After thinking for a while, Yu Xiu felt that his spirit had been soothed, exhaled lightly, and said secretly: "Then let's start." I saw him pinching three yellow fire talismans and inserting them in three positions in front of him, forming a three-legged formation.

After placing the talisman, Yu Xiu instantly closed his eyes, opened them for three minutes, closed them for seven minutes, and the yin spirit flickered and left the body. He landed among the three talismans in the posture of a yin god, sat down cross-legged, and immediately drank lightly:

"Burn!"

Three yellow fire talismans suddenly burst into flames, releasing a dazzling yellow light that instantly brightened the dim cavern as if it were day.

"Hiss!" At the same time, Yu Xiu's mouth also let out a cold hiss.

A sharp pain suddenly hit his heart, and it continued to flow, like the tide beating wave after wave.

"Ahh

Three red fire talismans were placed around his Yin God, burning by themselves, and the red and yellow flames that burned out of them hooked up and formed a circle of fire, firmly encasing his Yin God in it.

The flames spread over Yu Xiu's Yin God, directly turning his Yin God into a humanoid torch.

Yu Xiu had previously refined the Yin God, and he only used the Black Fire Talisman, although it was also painful, but it was only the pain of stabbing his fingers, and now he was burned by the Yellow Fire Talisman Yin God, and the pain had reached the level of peeling off his skin and breaking his fingers.

And he used the black fire talisman one by one, but now in order to break through in one fell swoop, he lit three fire talismans at once, three times the pain, and the pain was even more painful, making him feel like he had fallen into the oil pot for a while, and he was constantly being fried!

Pain, pain, pain! Such a sharp pain reminded Yu Xiu of how he felt when he first went out of his body.

"It's no wonder that the Taoist priest has to use the fire talisman to refine the Yin God first, and then he can use the sunlight to refine it...... Such severe pain is already unbearable, and if it falls directly into the sun, the horror will kill people alive!"

The purpose of the Taoist priest refining gunpowder is to simulate the sunlight, so that the Yin God can gradually withstand the scorching of the sun.

When Yu Xiu thought that he had wanted to walk directly into the sunlight before, he immediately felt fear in his heart.

After a few breaths, he slowly adapted to the severe pain, and his mind gradually calmed down, "It's just a lot of pain, how can you stop me!"

Yu Xiu picked up his hand, sat cross-legged in the flames of the fire rune, and began to visualize the White Bone Yaksha with all his might. Whew! A white bone rosette was born under his seat, and five white bone yaksha appeared silently.

Yaksha was armed with bone spears, guarding his side, and flames burned all over his body, like a soul seducer who had come out of the underworld.

The five Nakshatas opened their fanged mouths and roared silently, looking extremely hideous.

The bones of Yaksha's whole body were scorched by the yellow fire, and a trace of gray-black aura kept coming out, and the bones became more crystal clear.

Yu Xiu's spirit condensed to the extreme, and a bone on the rosette began to grow, slowly growing into the shape of a yaksha skull.

Finally, with his unremitting efforts, the shape of the bone is clearer, and it is about to change into the shape of the white bone Yasha.

At this time, the three fire talismans had also burned for more than ten breaths, and they were about to burn out.

Yu Xiu gritted his teeth, looked at the body sitting cross-legged in front of him, and drank in his heart.

The pillar of blood and smoke on the top of his body shook, and a stream of red light suddenly descended on the top of the Yin God, seeping into the Yin God, and was constantly scattered and refined.

With the help of the flesh, the bones on the rosette bloomed, and a new white bone yaksha grew, roaring and standing beside Yu Xiu.

The three fire talismans happened to burn out, and all of them turned into ashes and floated in the cave.

As soon as Yu Xiu opened his eyes, the six Yaksha turned around and pounced on him, escaping into the white bone lotus. His mind was completely revived, and as soon as his thoughts turned, he realized that he was able to use six uses of his heart and mind.

Yu Xiu lowered his eyes again, and saw that the lotus seat he was sitting on was growing a six-petal skull, and his yin god was much more condensed.

"Break through to the seventh grade, the realm of daily travel!" Seeing this scene, he was instantly overjoyed.

Yu Xiu paced in the cave, and his heart was full of ambition for a while:

"Immortal learning seven products, the realm of day travel, the soul of the Taoist priest is refined, can withstand the sun, can walk in the sun, in the fire. At this time, the Taoist priest has the ability to never forget!"

Yu Xiu thought of this, and thought about it again:

"The realm of day travel is divided into three classes such as morning travel, afternoon travel, and noon travel, if you can spend a day completely, and the yin spirit does not dissipate, you will break through to the realm of the six products of exorcism. At this time, the Taoist priest's divine soul thoughts can directly leave the body, and he can manipulate the magic weapon in the air to drive the flying sword to kill people......"

Thinking of the legendary immortal methods such as taking things from the air and killing people with flying swords, Yu Xiu's mind couldn't calm down for a long time.

He reluctantly looked away and looked outside the cave, and found that the sun had risen outside the cave, and the sky was faint.

"It's already a day trip, it's better to travel in the daytime......" Yu Xiu was eager to try.
