Preparations Before Awakening the Bloodline

After some playful banter, Lin Lei and Lei Lin bid the others farewell and headed to the laboratory.

After all, since they were going to stimulate the Azure Dragon Bloodline, the necessary data had to be collected. It was also a good opportunity for Lin Lei to help him replenish the materials for the Azure Dragon Bloodline, which he had been consuming heavily lately.

"Brother Lei Lin, can this thing really help me become a Dragonblood Warrior?" Lin Lei was still quite emotional about it; after all, this was simply too important for him and for the Baruch Family.

Lei Lin replied directly, "I'm not entirely sure!"

He truly wasn't certain. The more he researched the Azure Dragon Bloodline recently, the more he discovered the mysteries within it, and he no longer felt as confident as he had when he first made the promise.

But he wasn't worried; if it really came down to it, he would just drain the Saint Realm Silver Dragon belonging to Falling Leaf to activate Lin Lei's bloodline.

He currently had ten large buckets of Saint Realm dragon blood as material every month—enough to build a swimming pool for Lin Lei to soak in.

The reason he turned it into a potion was mainly to explore the mysteries of the Azure Dragon Bloodline.

Furthermore, he had become indifferent to whether helping Lin Lei awaken his bloodline would cause a butterfly effect. At worst, Lin Lei's transformation form in the future would lean toward a Silver Dragon and wouldn't look as cool as a Spine-backed Iron-Armored Dragon.

What truly mattered was the Azure Dragon Bloodline; the dragon blood used for stimulation was merely a key.

So, what kind of dragon blood it was didn't matter—it really didn't matter!

As for the butterfly effect, it had existed from the moment he appeared in the Coiling Dragon World. This was not something that could be changed by his personal will, so no matter how much he worried, it was useless.

"But don't worry, as long as you can endure the suffering, even if it fails, there will only be benefits and no harm."

"After all, this is dragon blood, a top-tier magic potion material! Even without any processing, it is a first-class treasure for strengthening the body."

Hearing this, Lin Lei felt relieved. Ever since Lei Lin promised to help him collect dragon blood to awaken his bloodline, he had also begun studying various knowledge related to dragon blood and knew that Lei Lin was right.

He took a deep breath, picked up a vial of dragon blood potion from Lei Lin's hand, and asked, "Brother Lei Lin, do I just drink it directly?"

Seeing Lin Lei's expression, Lei Lin snatched the potion from his hand and said, "What are you thinking? Drink it directly?"

"It seems you really don't know anything about hematology or pharmacology!"

"Skin test first!"

As he spoke, he took out a drop of the potion and placed it on the back of Lin Lei's left hand to observe the effect.

While Lin Lei stared blankly at Lei Lin performing the skin test, he looked at Delin, who was floating beside him, and asked, "Grandpa Delin, what is a skin test?"

"Why does it feel different from what you've been teaching me lately?"

Delin: "..."

A long while later, Lin Lei learned from his exchange with Lei Lin that the so-called [skin test] was a clinical testing method proposed by Lei Lin this year.

The academy's textbooks hadn't had time to include it yet, and only some students who took elective courses in pharmacology would understand it under the guidance of their teachers.

A quarter of an hour later, after recording the skin test data, Lei Lin asked, "Lin Lei, do you feel any discomfort?"

Lin Lei shook his head and said, "Nothing special, just some stinging and a burning sensation."

Lei Lin looked at the skin on the back of Lin Lei's hand, which had become red, swollen, and withered due to the skin test.

While applying a healing potion to him, he took out a drop of dragon blood potion made from Silver Dragon blood and dripped it onto the back of his right hand for a second skin test.

Feeling the significantly increased pain on the back of his hand, Lin Lei frowned and said, "Brother Lei Lin, the feeling of this drop of potion is much stronger than the last one!"

"Hmm, and there's a warm feeling, what's that about?"

He had learned his lesson and knew to take the initiative to explain the situation without Lei Lin having to ask.

Lei Lin nodded and said, "Oh, because this is the blood of a Saint Realm Silver Dragon, it's definitely more potent than the ninth-rank one."

"As for the warm feeling, that's because the Silver Dragon itself possesses the light attribute and carries a certain healing power, which is why you feel warm."

Lin Lei was stunned upon hearing this. He blinked his eyes and looked at Lei Lin, asking, "Brother Lei Lin, what did you just say?"

Lei Lin continued recording and said, "Silver Dragon blood, but it's a pity that the essence of dragon blood is too fierce; this bit of light power isn't enough to contend with the pain brought by the dragon blood's invasion."

"Otherwise, this dragon blood potion might not have needed to be mixed with rare and precious bloodline catalysts like Blue Heart Grass!"

Lin Lei said word by word, "No, I'm asking what you just said this Silver Dragon blood is..."

"Saint--Realm--Level--Dragon--Blood?!!!"

Watching Lin Lei's exaggerated expression of shock, Lei Lin shrugged and said, "Yeah, Saint Realm level, quite potent, right!"

After confirming that what Lei Lin said was indeed Saint Realm level, Lin Lei's expression immediately became incredibly complex.

After a long time, he muttered, "Saint Realm level Silver Dragon blood, what a pity, if only it were fresh!"

"Brother Lei Lin, for my sake, you actually used Saint Realm level dragon blood to make a potion!"

"The price paid for this dragon blood must be huge!"

"I..."

At this point, Lin Lei didn't know what to say. After all, he couldn't even imagine how precious Saint Realm level dragon blood was.

In this situation, whatever he said felt so pale!

Lei Lin instantly understood the surging gratitude in Lin Lei's heart, realizing that Lin Lei thought he had paid a great price for this Saint Realm Silver Dragon blood.

After realizing this, Lei Lin patted him on the shoulder without saying a word.

Between friends, there is no need for many words; a pat on the shoulder or a hug is enough.

However, his eyes drifted involuntarily toward several large vats in the corner of the laboratory, their surfaces covered in alchemical magic circles.

He wondered what Lin Lei's reaction would be if he knew those vats were filled entirely with Saint Realm Silver Dragon Blood.

"Alright, I'm not just doing this for you, but also for my own bloodline research."

"A real man shouldn't act like a sentimental girl."

As he spoke, Lei Lin pressed a button, and a bowl-shaped container the size of a bed slowly rose from the center of the laboratory.

The surface of the container was covered in intricate magic runes, and it was filled with a green medicinal liquid.

"The skin test showed no abnormal reactions, so let's proceed with the formal potion."

"This is a medicinal bath I specially formulated to stimulate your bloodline. Although it isn't as effective as Blue Heart Grass, it should still provide about thirty percent of the relief."

While explaining the effects of the liquid, Lei Lin activated the magic circles on the surface of the bowl-shaped container.

Before long, the liquid inside began to churn and boil, and wisps of steam mixed with the fresh scent of herbs permeated the entire laboratory.

Lin Lei didn't say a word and jumped right in; after all, his big brother Lei Lin had even gone to the trouble of obtaining dragon blood for him, so how could he not cooperate?

At this point, let alone testing a potion, even if Lei Lin asked him to climb a mountain of blades or dive into a sea of fire, he would do it!

"Hmm, why isn't this medicinal liquid hot?"
