There are not many utensils in the secret room, and it is not full of all kinds of things as Shen Li imagined, there is a round table in the middle, which is concave in the middle, like a stove.

"I'm going to start, don't come close, just watch from the sidelines. ”

Su You didn't procrastinate, with a wave of his big hand, a powerful wave spread from his body, Shen Li hurriedly retreated, arrived at a corner of the secret room, and watched quietly.

The fluctuations on Su You's body are getting stronger and stronger, and Su You, who has spread out his momentum, seems to have changed as a person, no longer the kind old man he used to be, but a real strong man, with sharp eyes and a straight back, like a heavenly spear.

Shen Li was secretly frightened, once the power of the Heavenly and Human Realm dispersed, even if it was not aimed at him, he felt a burst of coldness in his heart, under such power, killing him was really as simple as pressing an ant to death, and not even the slightest thought of resistance could arise.

In the face of Su You's powerful momentum, Shen Lizhong's pride because of the recent leaps and bounds suddenly disappeared, his own strength was too far from a real master, and besides, this world was too big, and the realm of heaven and man was not the end.

In the kung fu that Shen Li's thoughts flashed, Su You had already begun to move, and with a wave of his big hand, Tang Wanyu's long sword choked out of its sheath, the sword name was Han Yan, a rare famous sword, extremely sharp.

"Wow"

The light flashed in Su You's hand, and a red rune suddenly appeared in his hand, and then with a snort, it made a red flame, tumbling endlessly, wrapping the cold cockroach in it.

As soon as the flames appeared, the unbearable high temperature spread rapidly, Shen Li was now a cultivator of the third stage of the True Martial Realm, and at this stage, he was basically cold and heatless, but under this flame, although it was far away, Shen Li still felt bursts of burning, which showed how far its temperature had reached.

"This is the Samadhi True Fire, a powerful flame used in alchemy or refining, but when we forge runes, we don't want to melt the weapons, but only to soften the blade of the sword, so that we can easily seal the runes. ”

Su You calcined it while explaining to Shen Li, and after a quarter of an hour, the Han Claw Sword began to change a little, and the blade became transparent, with a hint of crimson.

During this period of time, Su You's hand did not move, he only relied on his telekinesis to levitate Han Yan in mid-air, and his expression was very casual, without a trace of embarrassment, which made Shen Li look breathtaking.

With Shen Li's current ability, it is not difficult to suspend objects out of thin air, but he can't do it as easily as Su You.

Suddenly, Su You moved again, the light in his hand flashed, and a pen suddenly appeared in his hand.

The pen is one foot and one inch long, and it is pitch black, but there are golden lines in it, like a golden dragon coiled on the tip of the pen.

Although Shen Li didn't know what kind of pen this was, he could see that this was definitely not an ordinary thing, as soon as the pen blade appeared, the powerful aura spread out, especially the nib, I don't know what kind of metal it is, the edge is dazzling, and it is difficult to be sharp.

"Do you know what this is?" asked Su You suddenly.

"The teacher should take out the talisman pen now, right?" Shen Li guessed.

"Yes, it's a rune. But don't underestimate this rune, although it is small, its own value is almost higher than that of some high-level runes. The rune pen is equivalent to the influence of a divine soldier on the warrior, which is of great help to draw the rune, but because its own value is too high, the average rune master is not qualified to have this rune pen. ”

"How precious?" Shen Li asked a question that was completely unleveled.

"For example, the one in my hand is only in the middle of the rune level, but it is comparable to a sixth, or even seventh-grade rune, which is priceless, and it is not an exaggeration to say that it is the most precious thing on my body. ”

"Six-seven-grade runes?" Shen Li was dumbfounded, a six- or seven-grade rune was truly valuable, and it could no longer be measured by gold and silver, but this small pen was comparable to a six- or seven-grade rune, and its preciousness could be seen.

While speaking, Su You's movements did not stop, and the talisman pen in his hand swiped at high speed in the air.

Looking at Su You's movements, Shen Li was really amazed, every line Su You drew seemed to be casual, but it implied the way of heaven, which was extremely mysterious and obscure.

With Su You's movements, faint trajectories appeared in the air, transparent, not obvious, but Shen Li could see it clearly, and he felt that the powerful aura seemed to be a life that was about to break through the ground, which was moving.

At this time, Shen Li really felt that casting talisman soldiers was really a technical job, and it was even more tiring. Su You's painting lasted for half an hour, and it barely stopped, and the brush strokes waved at high speed in the air, leaving traces one after another.

A quarter of an hour later, the light next to Su You flashed, and an inkstone suddenly appeared, Su You's pen was like electricity, and when he dipped it in the inkstone, he brought out a brilliant silver light, sprinkled into the lines in the air.

"Hah"

Su You let out a low shout, and in a flash, the silver ink in the inkstone suddenly flew out, converging on the pen, and turned rapidly.

"Wow"

Su You waved his arm suddenly, and the silver ink suddenly exploded, splashing on the lines in the air, Su You really deserved to be a king-level talisman master, although it was sprinkled, but the direction of every drop of silver ink was clearly calculated, and it fell in the most suitable place.

The silver ink sprinkled down, and the lines in the air suddenly became substantial, and the silver lines were intertwined, mysterious and obscure.

"Done!"

Su You shouted, the rune pen swung three times in a row, and the powerful telekinesis gushed out like a tide, the lines in the air suddenly condensed, and a silver rune suddenly took shape!

The runes are transparent, floating in the air, and they are void talismans that can only be drawn by king-level talismans!

"Go!"

Su You's wrist flicked, and the rune suddenly headed towards the Han Yan Sword Seal.

"Bang la la"

At the moment when the rune and the cold sword came into contact, the brilliant silver light suddenly rose, the sword blade surged at high speed, and there was even a loud wind, the void was agitated, and ripples appeared.

Su You's expression remained unchanged, the talisman pen swiped rapidly in the air, and every time he fell, the Han Mantis Sword stood still for a minute, and after Su You clicked five times, the Han Mantis Sword suddenly fell silent.

The majestic telekinesis filled the air, and the runes and the cold sword were also fused for the last time at this moment.

"Buzz"

With a roar, a dazzling silver light suddenly slashed out from the Cold Sword, and a piercing cold aura suddenly spread, as if it had suddenly entered the cold winter of Sixty-Nine.

Seeing that there were suddenly more silver lines on the blade, Shen Li knew that this talisman was done.
