The examination of blood Gu poison requires the Xuan Master to have extremely subtle and precise control over the vitality.

The Xuanshi Yuan Qi has a strong innate righteous qi, if the derived Yuan Qi is too strong, it will wipe out the little bit of Gu poison in the blood in an instant, and the verification effect of this blood will disappear immediately.

So Su Xi didn't ask Yan Ruyu to arrange for someone to verify the blood when it was collected.

First, there are so many people who don't look good at acting, and in addition, there is no way to rest in the middle, even a Xuan Master who has a very accurate control of the Yuan Qi is extremely prone to make mistakes under the control of the Yuan Qi for a long time.

What if it's wrong? Is it possible to call people back and take another blood?

There are still excuses for re-picking once or twice, but how many times are there too many?

Every piece of blood is unique, and each person's situation cannot be misjudged, so they only have one chance.

It must be absolutely perfect and correct, and there must be no mistakes.

However, the survival time of Gu poison in the blood is extremely short, and they must test all the blood within a day.

"Yu girl, can you help me?" Su Xi looked at Yu Xia.

As for Bai Zhenqian Wufeng, there is also a Cheng who is almost forgotten, but she directly ignored it.

"If Yueling is still there, there will be more helpers." Su Xi sighed again.

Bai Zhenqian and Ling Wufeng were extremely unwilling.

But they also knew that not to mention that they couldn't use their vitality for the time being, even if Su Xi first configured them with a quick-acting antidote, they could call on their vitality, and they didn't have the ability to guarantee that they would never destroy a piece of blood.

At this point, all they can do is not add to the chaos.

The three of them silently walked out of the house, leaving the space to Su Xi and Yu Xia.

Su Xi picked up the teapot and poured a glass of water, then hooked his fingers, and a crystal bubble floated into the air.

"You wrap your vitality close to the bubble and be careful not to burst it."

Yu Xia Yiyan stretched out his hand, and his palm was full of vitality.

The bubbles that were originally floating in the air were suddenly frozen, not up or down, and not moving at all.

Su Xi nodded with satisfaction.

Because she saw a cyan aura floating out of Yu Xia's palm, lightly and gently wrapping the bubbles, the force was not too big or small, it was very suitable.

"You are really naturally suitable to learn from me the ability to debate Gu and solve Gu." Su Xi sighed with emotion, and looked at Yu Xia's eyes that lit up slightly.

"Let's start with the earliest blood collected in order, box by box inspection, don't miss a bottle, if you are tired, don't force it, sit down and breathe for a while, and recover your vitality. We are fast, but we are more stable, do you understand? ”

Yu Xia nodded, neither of them spoke again, extinguished the candle in the room, and stood by a box in the dark, opened the wooden box, and tested the blood bottle by bottle.

Pull out the cork, wrap the blood in the porcelain bottle with vitality, and then gently pull it out to see if the blood emits red light in the dark.

The same process was repeated over and over again, when Yu Xia finished checking the first box, a cold sweat broke out on her forehead, she swallowed a Taiyuan pill, and sat on the spot to breathe, she deliberately paid attention to Su Xi, she was testing the second box of blood, and the progress had just begun.

That meant that there were nearly six boxes left, and 7,200 vials of blood.

A little more than half of the progress has passed, and four hours have passed.

Su Xi was also a little anxious, but he only calmed down and steadily controlled the output of vitality.

It's not the way to go.

Because their speed will only get slower and slower with the long inspection, and the time will only become less and less.

Yu Xia twisted his eyebrows and suddenly spoke.

"Aunt Su, do we have to test each bottle one by one?"

Su Xi was stunned when she heard this, and stopped what she was doing.

"Or else? This is something that requires extremely precise control of the vitality, even if you test most of the Xuan Masters one bottle at a time, you may not be able to do a good job, how many bottles do you want to do at a time? ”

Yu Xia felt that the vitality in his body had almost recovered, so he stood up.

In my mind, I thought about the skills of weaving nets with vitality in the booklet left by Chen Daoren.

The original intention of that spell was to turn the vitality into a large net, trapping the opponent in the middle, and it was a range-based binding skill.

What if she only used vitality as a thread, but did not weave a web?

Yu Xia glanced at the glass of water that Su Xi poured before, shook it slightly, and many bubbles immediately appeared on the edge of the water surface.

Yu Xia spread her palms, ten fingers danced lightly, and from her fingertips, ten faint rays of light stretched out, extending towards the water glass.

"Do you want to verify ten blood samples at once?"

Su Xi was shocked and couldn't help shaking his head.

"No, it's impossible, the length and thickness of the ten fingers are different, and the power of the same Yuan Qi will also change, how can you accurately control the Ten Yuan Qi?"

"It's so whimsical."

Yu Xia didn't seem to hear it, and only guided the ten Yuan Qi to wrap a bubble from the cup, the Yuan Qi was light and thin, and the bubbles were also very obedient, trembling and floating into the air.

Su Xi was about to be surprised, only to hear the sound of "pop", and the bubble connected to the ring finger of Yu Xia's left hand burst.

Su Xi shook her head helplessly, "Miss Yu, I know you have good intentions, and the time is indeed a little rushed, but it is not advisable to rush in like this." I have already instructed someone to ask her to come over to help as soon as Yueling comes back, and she may be able to come in time then. ”

The big family that Yan Yueling went to today is the old lady's 60th birthday, and she can't break up if she doesn't have a lively day, and when she comes back, I don't know when it will be.

This is actually the next step.

It's just that Daoyuantang has so many people to use, and they really can't find anyone who can help.

The strength of the two five-grade ones in the prison may be enough, but those two people have ghosts in their hearts, so how can people rest assured that such an important matter will be handed over to them?

Su Xi was stunned for a moment, but Yu Xia had already re-triggered ten thin lines and re-pulled out ten bubbles.

Su Xi sighed, didn't care about her anymore, and only re-examined the blood in front of her.

The room was still pitch black, which was not affected at all by Su Xi, who had excellent eyesight.

To her relief, there had been no red light until now.

After she finished testing the three bloods, she found that she didn't hear Yu Xia's movements.

Still battling bubbles?

Su Xi stopped what he was doing and looked at Yu Xia with a frown.

If you want to delay time so indiscriminately, then you have to talk about her.

As a result, as soon as she turned her head, she was stunned.

Yu Xia's face was full of smiles, her eyes were bright, her ten fingers were tapping happily, and the ten bubbles she was pulling also floated up and down with her movements.

These bubbles were wrapped in her vitality steadily, no matter how Yu Xia pulled them, the bubbles never burst from beginning to end.

Incredibly strong.
