After the secondary occupation reached the maximum level, I wore it

A small pile of ice-attributed spiritual materials was placed in front of him, emitting a chill that penetrated into the bones.

“Three and a half taels of ice spirit beast blood, one tael of ice jade spirit stone chips, seven and a half qian of snow lotus heart powder…” Shi Yu pointed at a few prepared spirit materials, mixed them carefully and ground them evenly, and the talisman ink was ready.

The prepared talisman ink was a pool of icy blue, like a piece of solidified amber, with wisps of white mist wafting out from time to time, giving off an chilling feeling.

Seeing that the ratio of talisman ink was just right and there was no need for adjustment, she then took off the two horns from the spirit beast's corpse and used them as talisman pens, and the tanned and processed spirit tree bark and small pieces of animal skins as talisman paper.

When others watched Yu holding the horn of the spirit beast and dipping it into the blue liquid, and drawing the spiritual energy to paint on the bark of the spirit tree, his expression became a little numb and dazed, and he began to try to convince himself.

"If I'm not mistaken, this should be making a talisman?"

"The formation and the talisman are connected. Since she has profound attainments in the formation, it is only natural that she can make talismans..."

"Really? When I get out of the secret realm, I will go back to my family and ask my aunt, who is a formation master, if she can make talismans..."

Outside the Xuanguang Mirror, all the teachers were watching the scene inside. Suddenly, one of them asked Jiang Tingchuan out of the blue, "Master Jiang, the formation and talismans are connected. Can you make talismans?"

Jiang Tingchuan: “…” He actually wanted to.

"My talent is limited." Jiang Tingchuan answered honestly, paused, and then said, "Although I don't know how to do it, I still have some knowledge. What Shi Yu made at this moment, if I am not mistaken, is a lightning protection talisman."

After he said this, all the commanders looked at Commander Shangguan.

Commander Shangguan moved his fingers, a trace of confusion appeared on his grief-stricken face. He thought he had heard it wrong, and repeated: "Lightning protection talisman...?"

……

Shi Yu put down his pen and moved it around, quickly sketching out the first source pattern. The talisman ink seemed to have life, extending onto the talisman paper. The ice-blue lines meandered, revealing a faint and deep glow, which was extremely beautiful.

She then drew the second and third lines, drawing them smoothly and without any stagnation. After a total of nine source patterns, a fourth-grade lightning protection talisman was completed.

If lightning-proof talismans are classified by grade, there are fifth, sixth, seventh and even higher grades. However, the conditions are limited at the moment, so we have to make do with everything and can only make this fourth-grade lightning-proof talisman.

Fortunately, although it is a fourth-grade product, its quality is excellent and it can be used. At worst, we can win by quantity.

Time was tight, so Shi Yu did not rest. After finishing the first picture, he started the second one immediately.

"When the next thunderbolt comes, throw all five lightning-avoiding talismans towards Ning Yishui." She drew five talismans in total, then stacked them together, gave instructions, and started drawing the next one without even looking up.

"Okay. Leave it to me." Bai Jiang picked up five lightning-proof talismans, held them tightly in his hand, took a deep breath, and stared at the calamity clouds in the sky.

When the thunders intertwined in the air and the next thunderbolt was brewing and about to strike, Bai Jiang quickly threw five lightning-proof talismans to Ning Yishui.

"boom--"

Five lightning-proof talismans flashed to Ning Yishui's side like flowing lights, emitting an ice-blue light in the air and quickly forming a thin film that wrapped Ning Yishui.

The thunder still struck him accurately, but in an instant the blue light became brighter and cold air filled the air. The power of the thunder seemed to be filtered through several layers by the thin film, and when it fell on Ning Yishui, it was no longer as strong as before.

Everyone's tense hearts suddenly relaxed.

"effective!"

Shi Yu did not look up, still concentrating on making the talisman.

The intervals between the arrival of heavenly thunders were slightly shorter than the time required for her to make five talismans. She was already very exhausted at this point, and had no choice but to cheer herself up and barely increase her speed.

However, the spirit beast's horn was not a genuine talisman pen that had been carefully refined. After drawing dozens of them, it began to be unable to withstand the spiritual energy and several cracks appeared on the horn.

Shi Yu replaced this horn and took out another one from a spirit beast to continue making talismans.

Everyone looked at her continuously and non-stop method of making talismans, opened their mouths, and looked at each other with complicated expressions.

Ever since Ning Yishui began to overcome the tribulation, Shi Yu has hardly stopped and has not had time to rest until now. There are only a few things they can do and most of the time they can only watch, feeling both admiration and shame.

After drawing the twentieth lightning-proof talisman, Shi Yu's consciousness was already exhausted. She closed her eyes and felt an abnormal swelling and pain in her head, as if someone was stirring it inside, making it difficult for her to even breathe.

If she had not stopped practicing the Soul Tempering Technique for a long time, she would not have been able to hold on until now.

Biting the tip of his tongue, Shi Yu forced out his blood and essence, and relying on this drop of blood and essence to continue making talismans.

After all, she has the spring water, and the consumed blood and energy can be restored quickly.

However, this scene was shocking to others.

To consume essence and blood is tantamount to shaking the foundation of one's Taoism. Unless it is absolutely necessary or a matter of life and death, one must never use essence and blood. Otherwise, at best one will suffer from blood deficiency, at worst one's cultivation will regress, one's soul will be damaged, and even one's lifespan will be shortened!

She, she has such a pure heart, she can do this for her classmates.

Several thoughtful female cultivators present were deeply touched. They looked at Shi Yu with tears in their eyes and secretly decided that they would take good care of her after they left this secret realm.

The teachers outside the secret realm were also very moved when they saw this scene.

"This girl...it's hard for her..."

Ning Yishui, with the help of the lightning protection talisman, was finally able to catch his breath. However, the might of the thunder was still earth-shaking, and the thunder tribulation had come to the last few, roaring even more.

Ning Yishui gritted his teeth, and circulated his spiritual power to the extreme, and the meridians in his body seemed to be torn apart. He knew that he could not relax at this moment, and these last few thunder tribulations would determine his life or death, and if he was not careful, he might die.

Shi Yu also knew that the most critical and dangerous moment had come. The movements of her hands almost turned into afterimages. She squeezed all her potential to complete one lightning-proof talisman after another. A few more drops of blood and essence were forced out, and at this time her face was as pale as gold paper.

Suddenly, an extremely cold breath enveloped her from somewhere. Shi Yu was caught off guard and was so cold that she vomited blood.

"Shi Yu!" Everyone was shocked, thinking that Shi Yu had damaged her essence due to the loss of her blood essence, and they gathered around her. But seeing that even though she was coughing up blood, her hands did not fluster at all and she was still drawing the lightning-proof talisman, they did not dare to help her or touch her, and could only feel anxious.

Shi Yu's eyes narrowed, and he cursed at the unknown cold breath in his heart: "No matter what you are doing, don't think of disturbing me at this time!"

Her blood and essence began to burn again. A more intense pain and burning sensation than before spread from deep within her body. Even her skin began to crack. Blood continued to seep out of it, staining her clothes red. Even her bones made a sound of breaking, which was terrifying.

However, all this made Shi Yu even more excited. Her blood was born to die. The more extreme it reached and the more painful it was, the more happy she felt!

Ning Yishui in the sky sensed something and glanced down, taking in Shi Yu's horrifying appearance. His heart trembled instantly.

This one glance made his faith stronger than ever before.

Finally, the last of the eight or nine thunder tribulations is coming!
