"Is the princess going back?"

Looking at Diana who entered the door, Qin Tianchen smiled and said politely.

"Yes, it's been so long, just now my imperial brother called and asked me to go back!" Diana said with a smile: "But thank you Qin, I am very grateful for my hospitality these days!"

"And ...... We, the subjects of the Great British Empire, will also be grateful to Qin!"

After speaking, Diana smiled and bowed to Qin Tianchen.

She is very pious in this ceremony!

Sun Sisi on the side was in a hurry.

Looking at this meaning, it was clear that Diana had already mastered the formula of the life spirit liquid, otherwise why would she say that the people of the British Empire were all grateful to Qin Tianchen?

Sun Sisi hurriedly signaled to Qin Tianchen and asked him to hurry up and find a way to keep Diana.

However, Qin Tianchen didn't care at all, but nodded and said, "Okay, since that's the case, then Qin won't be far away, I'll let them come over and send the princess to the airport!"

After speaking, he took out his mobile phone and called the Huaxia official in charge of Diana's trip.

Sun Sisi was so anxious that she couldn't do it, but Qin Tianchen didn't speak, she didn't dare to interject, so she could only stomp her foot in hatred, then turned around and went to find Xu Shaolin.

After a while, she went and returned.

Behind him was also panting Xu Shaolin.

But at this time, in the office, except for Qin Tianchen who was sitting on the sofa, there was no trace of Diana.

"Mr. Qin...... You let her go?" Sun Sisi's eyes widened and he asked in disbelief.

"Who?"

"Princess!"

"Let's go, the car should have just started. Qin Tianchen nodded and said noncommittally.

Sun Sisi was in a hurry, hurriedly ran to the window, and looked out, sure enough, Diana's convoy had started and headed towards the outside of the school.

"Mr. Qin!"

"You're confused!"

At this time, I saw Xu Shaolin heartbroken, his body trembled, patted his thighs, and looked remorseful.

Qin Tianchen shook his head, smiled helplessly, and did not persuade Xu Shaolin, but got up and walked out.

"Come with me, both of you!"

With that, he left the office straight away.

Sun Sisi and Xu Shaolin were stunned and looked at each other blankly, but the stakes were very high, so they hurriedly followed.

In the laboratory, led by Qin Tianchen, the three of them gathered in front of a small platform.

On the countertop, there are several test tubes and a piece of paper.

"This is the recipe for the Life Spirit Liquid!" Pointing to the piece of paper, Qin Tianchen said.

Xu Shaolin and Sun Sisi's faces changed, and both of them showed a touch of surprise and solemnity.

Unexpectedly, Qin Tianchen actually showed them the formula.

Solemnity is so important to this thing, Qin Tianchen actually wrote it on the paper at random like this.

"Now, you guys follow the recipe and see if you can cultivate the Life Spirit Liquid!" Qin Tianchen said lightly.

Xu Shaolin and Sun Sisi were confused, glanced at each other, and didn't speak, so they followed Qin Tianchen's instructions to debug.

More than 20 minutes later, each of them had an extra dose of test tube in their hands.

"Mr. Qin, we've got it!" Xu Shaolin said.

"Okay!" Qin Tianchen nodded, and then said, "You can test it again and see if what you have debugged is the life spirit liquid!"

After speaking, he found a seat and sat down, and watched the two of them test with a smile.

Ten minutes later.

"How is that possible!"

"This is clearly debugged in strict accordance with the formula, but the test results show that this is an ordinary tube of water, what's going on!"

Xu Shaolin's eyes were full of surprise, and he looked at the test tube in his hand in disbelief, and he couldn't come back to his senses for a long time.

"I ...... This is also the result of me!" Sun Sisi on the other side swallowed his saliva with difficulty, and his expression at the moment was the same.

Surprised, surprised, puzzled!

But soon, the faces of the two changed at the same time, and they both looked at Qin Tianchen who was smiling.

"Mr. Qin, what the hell is going on?"

"Yes, why is it that the best test result of a good life spirit liquid is just a pipe of wastewater?"

Xu Shaolin and Sun Sisi pronounced successively, with a lot of incomprehension.

Qin Tianchen smiled slightly, and then said, "Now you don't have to worry!"

"The princess of the empire worked hard for ten days, but the result she got was the same as the two of them, it was not a life spirit liquid, but a pipe of wastewater!"

Qin Tianchen was calm and calm, with a faint smile on his expression, and a temperament of wisdom beads in his hand emanated.

Qin Tianchen said this, and although Xu Shaolin and the others breathed a sigh of relief on their faces, their doubts became deeper and deeper.

Princess Diana was busy in vain, and they were naturally happy.

But at this moment, this mystery lingers in their hearts, and the two of them are also unable to sleep.

"The reason why the life spirit liquid is called the life spirit liquid, the most critical place lies in this spirit word!" As if knowing that the two of them didn't know the reason, they would definitely not give up, Qin Tianchen smiled and began to explain.

"The recipe is right, the process is also right, but the spiritual fluid can't come out, why? because there is no aura!"

"You can understand Reiki as a trace element between heaven and earth!"

"Look at the production of yeast, it is devouring the aura between heaven and earth, using it to ferment and strengthen itself, and then reproduce more of this trace element, so that there is a life spirit!"

"The difference in the middle is to let the yeast, that is, the pipe of waste water in your hands now, have the ability to devour aura!"

"And this ability, what is needed!"

As he spoke, he saw Qin Tianchen conjuring up a trick and taking out a turquoise disc from his hand.

This disc is the size of a palm, it looks jade smooth and unusually full, and if you look closely, it is carved with dense runes and all kinds of strange lines.

This jade plate is a magic circle for absorbing spiritual power!

"With the formula, coupled with this jade plate, the two are combined into one, and you can produce a large number of life spirit liquid, which is the origin of life spirit liquid!"

"In short, the formula is just to research the source body that can devour the aura, and this jade plate is the key to the devouring effect!"

"Even if Princess Diana steals the formula, even if she learns biology for another fifty years, she will definitely not be able to produce life spirit liquid, so why should the two of you worry?"

Qin Tianchen looked at the two of them with a smile.

This jade plate magic circle, if it is not a monk who is proficient in cultivation, it cannot be engraved at all.

And to mass-produce the life spirit liquid, the formula is secondary, and the main thing is the magic circle of this jade plate.

This circle is similar to a miniature version of the Spirit Gathering Array, except that it also contains twenty-eight formations such as the Spirit Attracting Array, the Spirit Formation Array, and so on!

In this world, except for Qin Tianchen, no one else will be at all.

Even if he is an apprentice of his teaching, although he can be regarded as a monk, he has not studied the formation, so there is no need to mention mastering this thing!

Xu Shaolin and Sun Sisi hurriedly took the jade plate, and then poured the waste water in the test tube on the jade plate, and after a while, the water was taken to the test again, and sure enough, the result this time was really the spiritual liquid of life!

The two of them suddenly realized, and immediately couldn't help but shake their heads and laugh.

Feelings: Mr. Qin had already prepared, but they were still anxious like ants on a hot pot.

But knowing this effect at this moment, the two of them breathed a sigh of relief.

Even if she gave this jade plate to Diana, she couldn't see the magic of this thing at all, what was the use of just stealing a formula?

In fact, Qin Tianchen didn't mean to hide it from the two of them.

The main thing is that the more anxious they behave, the easier it is for Diana to believe that what she got is the formula of the life spirit liquid! This can be described as stealing the dragon and turning the phoenix, and putting this imperial princess alive.
