Kryptonian cultivation, invincibility starts from opening the Demon Suppression Tower

He skillfully picked up a medicinal plant, threw it into the alchemy furnace, and then mobilized the spiritual power in his body to draw out a ray of spiritual fire.

Under his control, the spiritual fire gently wrapped the medicinal materials and began to refine them.

Shen Lang watched the changes in the alchemy furnace with all his concentration, and beads of sweat gradually appeared on his forehead.

First, refine the medicinal materials and extract the essence of each medicinal material. Then control the spiritual fire and carefully fuse these essences.

Shen Lang's hands kept changing the techniques, and the temperature of the spiritual fire rose and fell according to his thoughts.

This is a very long and extremely testing step. If the temperature of the flame, the refining method, and other factors are slightly wrong, the furnace elixir will be destroyed.

The temperature of the flame needs to be accurate to the nearest millimeter. If it is too high, the medicinal materials will be instantly reduced to ashes. If it is too low, the essence cannot be extracted. The refining technique must be smooth and flowing. A slight pause or hesitation may lead to fusion failure.

As for other factors, such as the stability of the alchemy environment, the input rhythm of spiritual power, etc., any slight error may lead to catastrophic consequences.

For example now...

There was a loud "boom".

A deafening explosion sounded in the house, instantly breaking the originally peaceful and tense atmosphere.

A powerful impact raged around, the entire room was shaking violently, and tiny cracks appeared on the walls.

Shen Lang exploded.

Thick smoke billowed out from the alchemy furnace, instantly filling the entire room, and the pungent smell filled every corner.

The fragments of the alchemy furnace were flying everywhere, like sharp hidden weapons, making people shudder.

Fortunately, Shen Lang was properly protected and was not injured.

At the moment of the explosion, Shen Lang quickly activated the protective barrier that had been arranged in advance.

A layer of light blue light instantly enveloped him, and the flying fragments and raging impact hit the barrier, causing ripples.

Shen Lang's eyes were filled with annoyance and reluctance, but more importantly, he was happy.

He looked at the mess in front of him with lingering fear, secretly glad that he was cautious and thoughtful and did not let this accident cause him any substantial harm.

"This seventh-grade elixir is indeed unusual. It is much more difficult to refine than the sixth-grade elixir."

Shen Lang looked at the messy alchemy land in front of him and muttered to himself.

He frowned, his expression solemn, and his eyes were full of reflection on the failure of this alchemy.

The spiritual power control required by the seventh-grade elixir, the timing of the fusion of medicinal materials, and the subtle changes in the flame temperature are all so complex and delicate that they are far beyond the reach of the sixth-grade elixir.

While Shen Lang was cleaning up the remains of the alchemy furnace, he was summarizing the lessons in his mind.

However, alchemy had been successful once before, especially such a high-level elixir. Fortunately, Shen Lang had prepared two more ingredients.

"Fortunately, I had the foresight to prepare enough medicinal materials, otherwise this failure would have really wasted all the efforts."

Shen Lang secretly rejoiced. He walked to the cabinet where the medicinal materials were stored and once again confirmed the quantity and quality of the remaining medicinal materials.

After taking a short rest, Shen Lang once again started refining elixirs in a familiar way.

He took a deep breath, adjusted himself, and regained his composure.

Shen Lang formed a seal with his hands, relit the alchemy furnace, and the flames rose.

Shen Lang was more cautious than before, without any distractions, and only had this furnace pill in his eyes. He concentrated on controlling the temperature of the flame, and the output of every trace of spiritual power was extremely precise, and he did not dare to slack off in the slightest.

I don’t know how long it took, but there was a sudden movement in the alchemy furnace, and a strange fragrance slowly overflowed.

The scent was like a soft thread, quietly entering Shen Lang's nose, instantly refreshing him.

His originally tense face moved slightly, and a hint of surprise flashed in his eyes.

Shen Lang's face was filled with joy, knowing that this was the prelude to becoming a pill.

"Finally successful!" He cheered secretly in his heart, and at the same time he did not dare to relax at all.

Shen Lang didn't dare to be careless and gathered 120,000 points of mental power to control the spiritual fire.

His eyes were fixed on the alchemy furnace, the veins on his forehead popped out, and big beads of sweat rolled down his cheeks, but he didn't bother to wipe them away.

Compress and re-compress the elixir in the furnace.

Shen Lang's mental power was like an invisible big hand, accurately controlling every ounce of power and constantly squeezing and condensing the elixir.

finally!

Dan is done!

A shining elixir jumped out of the single furnace, and immediately rushed out as if it had some intelligence.

The elixir was surrounded by light, as if it had its own consciousness, wanting to break free and fly to freedom.

With quick eyes and quick hands, Shen Lang used his mental power to condense an invisible barrier to wrap the Nine-turn Nirvana Pill, and then placed it in the medicine bottle.

His movements were as fast as lightning, his mental power exploded instantly, and the barrier formed was as solid as a rock, leaving the elixir that wanted to escape nowhere to escape.

Shen Lang carefully controlled the barrier and slowly introduced the elixir into the prepared medicine bottle. When the elixir fell steadily into the bottle, he finally let out a long sigh of relief.

Then he opened the barricade outside the house and prepared to go to the eighth senior brother and tell him the good news.

Shen Lang's face was filled with the joy of success, and he walked briskly towards the door.

He couldn't wait to share this hard-won achievement with others, and happily looked forward to the surprise expression on the eighth brother's face when he heard the news.

But the next second, Shen Lang saw that the yard was filled with paper cranes used to send messages.

The paper cranes were piled up like snowflakes, almost covering the entire yard, forming a white "sea".

Shen Lang was shocked by the scene in front of him and his eyes widened. The smile on his face froze instantly.

Because Shen Lang opened the ban to prevent interruptions before he went into seclusion, so as not to be disturbed during the alchemy process.

So he could not receive other people's voice transmissions from thousands of miles away, and those who had urgent matters to find him could only leave messages with paper cranes.

Wait until Shen Lang came out of seclusion, and then check them one by one.

"Why are there so many paper cranes? What happened?" Shen Lang frowned, and a bad premonition surged in his heart.

He looked at the piles of paper cranes and felt an inexplicable pressure and confusion.

"Did something major happen?"

Shen Lang muttered to himself while carefully stepping into this "sea of ​​paper cranes", ready to check the information conveyed by these paper cranes one by one.

Shen Lang casually unfolded a piece of paper, which was sent by Xue Yameng: After the paper crane was unfolded, the handwriting on it was beautiful and neat, as if one could see Xue Yameng's serious writing.

"The Ten Sects Competition will begin in five days. Disciples from each sect must first go to the Foreign Affairs Hall of the Tiandao League to receive their name tags. We will go together then."
