Preparations Before Awakening His Bloodline

After some playful teasing, Lin Lei said goodbye to the others and went to the laboratory.

Since they were going to awaken the Azure Dragon Bloodline, they still needed to gather the necessary data. It was also a good opportunity for Lin Lei to replenish the materials for the Azure Dragon Bloodline, which he had been using up rapidly lately.

"Big Brother Lei Lin, can this really help me become a Dragonblood Warrior?" Lin Lei was still quite excited. After all, this was incredibly important to both him and the Baruch Family.

Lei Lin answered frankly, "I'm not sure."

He really wasn't sure. The more he studied the Azure Dragon Bloodline, the more he realized how mysterious it was. He no longer felt as confident as he had when he first made his promise.

But he wasn't worried. If all else failed, he could simply draw blood from Falling Leaf's Saint Realm Silver Dragon and use it to awaken Lin Lei's bloodline.

The materials he had for ten large barrels of Saint Realm dragon blood each month would be more than enough to build Lin Lei a pool to bathe in.

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

Besides, he had made peace with the possibility that helping Lin Lei awaken his bloodline might cause a butterfly effect. At worst, Lin Lei's transformed form might take after a Silver Dragon, rather than the much cooler Spine-backed Iron-Armored Dragon.

What truly mattered was the Azure Dragon Bloodline. The dragon blood used to stimulate it was just a key.

So it didn't matter what kind of dragon blood it was. It really didn't matter!

As for the butterfly effect, it had begun the moment he arrived in the Coiling Dragon World. It wasn't something he could change through sheer force of will, so there was no point in thinking about it too much.

"But don't worry. As long as you can endure the pain, even if it fails, you'll only benefit from it. There won't be any harm."

"After all, this is dragon blood, a top-grade magical ingredient! Even untreated, it's one of the best treasures for strengthening the body."

Lin Lei felt reassured. Ever since Lei Lin had agreed to help him gather dragon blood and awaken his bloodline, he had been studying all kinds of things related to dragon blood. He knew Lei Lin was right.

He took a deep breath and picked up a tube of dragonblood potion from Lei Lin's hand. "Big Brother Lei Lin, do I just drink it?"

Seeing Lin Lei's expression, Lei Lin snatched the potion back. "What are you thinking? You can't just drink it!"

"You really haven't learned anything about bloodline studies or potion-making, have you?"

"First, a skin test!"

As he spoke, he took a drop of the potion and placed it on the back of Lin Lei's left hand, then watched for a reaction.

As Lei Lin performed the skin test, Lin Lei stared blankly at him, then looked at Doehring, who was floating beside him. "Grandpa Doehring, what's a skin test?"

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

Doehring: "..."

Only after a while did Lin Lei learn from Lei Lin that the so-called skin test was a clinical drug-testing method Lei Lin had introduced this year.

The academy's textbooks hadn't been updated to include it yet. Only some students who had taken magical pharmacology electives knew about it from their teachers.

A quarter of an hour later, after recording the skin-test data, Lei Lin asked, "Lin Lei, are you feeling uncomfortable anywhere?"

Lin Lei shook his head. "Nothing unusual. It just stings a little and feels like it's burning."

Lei Lin looked at the back of Lin Lei's hand, where the skin had become red and swollen, grayish, and withered from the skin test.

As he applied a healing solution, he took a drop of dragonblood potion made from Silver Dragon blood and placed it on the back of Lin Lei's right hand for a second skin test.

Feeling the pain in his hand intensify, Lin Lei furrowed his brow. "Big Brother Lei Lin, this drop feels a lot stronger than the last one!"

"Mm, why does it also feel a little warm?"

He'd learned his lesson and now volunteered information instead of waiting for Lei Lin to ask.

Lei Lin nodded. "That's because this is blood from a Saint Realm Silver Dragon. It's bound to be stronger than the blood of a ninth-rank dragon."

"As for the warmth, that's because Silver Dragons have an affinity for light. They naturally possess a certain healing power, which is why it feels warm."

Lin Lei was stunned. He blinked at Lei Lin. "Big Brother Lei Lin, what did you just say?"

As he took notes, Lei Lin replied, "Silver Dragon blood. Unfortunately, dragon blood is too powerful by nature, and this little bit of light power can't counteract the pain caused by the dragon blood invading your body."

"Otherwise, we might not need to mix in a rare and precious bloodline catalyst like Blue Heart Grass!"

Lin Lei enunciated each word. "No, I'm asking what you just said about this Silver Dragon blood being..."

"Saint—Realm—Dragon—Blood?!"

Looking at Lin Lei's exaggeratedly shocked expression, Lei Lin shrugged. "That's right. Saint Realm blood. Strong stuff, huh?"

Once he confirmed that Lei Lin really meant Saint Realm blood, Lin Lei's expression immediately turned complicated.

After a long while, he murmured, "Saint Realm Silver Dragon blood. What a pity it would be even better if it were fresh!"

"Big Brother Lei Lin, you actually used Saint Realm dragon blood to make a potion for me!"

"That dragon blood must have cost you a great deal!"

"I..."

Lin Lei didn't know what else to say. He couldn't even begin to imagine how precious Saint Realm dragon blood was.

In a situation like this, whatever he said would sound utterly inadequate!

Lei Lin immediately understood how deeply grateful Lin Lei felt. He realized that Lin Lei thought he had paid an enormous price for the Saint Realm Silver Dragon blood.

After understanding all this, Lei Lin patted Lin Lei on the shoulder without saying a word.

Friends didn't need to say much. A pat on the shoulder or a hug was enough.

Still, his eyes involuntarily drifted toward several large barrels in the corner of the laboratory. Their surfaces were covered in alchemical magic arrays.

He wondered how Lin Lei would react if he found out that those barrels were all filled with Saint Realm Silver Dragon blood.

"All right, I didn't do this just for you. It's also for my own bloodline research."

"A man should act like a man. Don't get all sentimental."

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

The container's surface was covered in complicated magic-array markings, and it was filled with green liquid.

"The skin test showed no unusual reactions. You can take the potion properly now."

"This is a medicinal bath I specially prepared to awaken your bloodline. It won't work as well as Blue Heart Grass, but it should still relieve about a third as much pain."

As he explained the liquid's effects, Lei Lin activated the magic array on the surface of the bowl-shaped container.

Before long, the liquid inside began to boil. Wisps of steam, carrying a fresh herbal fragrance, spread throughout the laboratory.

Without a word, Lin Lei jumped in. His big brother, Lei Lin, had gone so far as to get dragon blood for him. How could he not cooperate?

At this point, he'd do anything for Lei Lin. It didn't matter if Lei Lin asked him to test a potion or walk through fire and climb a mountain of blades!

"Mm, why isn't this liquid hot?"
