In the Nibelungs, Su Mo poured the warm food into the mouth of Fenrir, who lay down obediently with his head open and his mouth open.

"Thank you good friend!"

Fenrir forced these words out of his throat.

You can also make sounds in this posture. The structure of dragons is really strange.

"You're welcome."

Su Mo shook his head and subconsciously looked at his personal panel.

[Breeding: LV2, 1120/10000 (You have initially mastered the breeding skills and can better train pets and improve their strength and intimacy)]

The experience value of breeding skills has been increased by 20 points.

Although it doesn't look like much, you have to know that Xia Mi didn't come this time. Fenrir increased his score by twenty points when he knew that Su Mo was the only one.

It shows that after the long-term binding between Su Mo and Xia Mi appeared, the equation in Fenrir's mind changed from the appearance of a good friend = the appearance of a sister = his own happiness, to becoming more direct, to the appearance of a good friend = his own happiness.

This means that the relationship between the two has taken a further step. After understanding this, Su Mo is more confident about what will happen next.

He put the metal box containing the serum aside.

He got this from the refrigerator openly when he was packing leftovers for Fenrir, while Xia Mi was lying dead on the bed.

Although if the Dragon King listened carefully, Su Mo's actions might not be hidden from her, but Su Mo had experimented several times before and confirmed that Xia Mi was not wary of him, and would not be aware of anything even if he heard it.

Take it to your heart.

After Fenrir finished eating, Su Mo took out an empty test tube and asked directly.

"Fenrir, can you lend me some of your blood?"

"Huh? Good friend, what do you want this for?"

Fenrir, who had just finished eating, was a little confused.

No matter how stupid he is, he still knows that his blood cannot be given casually.

It's not that I don't want to, it's that it's too dangerous.

"it works."

Su Mo shook his head, not intending to explain too much, so as not to worry the silly dragon, so he told Xia Mi.

"According to the agreement, if it is a request from a good friend, it is indeed possible. But my sister said that my blood is very dangerous!"

Fenrir unexpectedly readily agreed to his request, with just one more reminder.

He would agree to Su Mo mainly because he and Su Mo had an agreement, Su Mo would help him protect his sister, and he would listen to Su Mo's words.

Since you have made an agreement to be obedient, a little sacrifice of blood is naturally nothing.

Although Fenrir was stupid, he would not really agree to such a thing just for a bite or two.

"Don't worry, I understand the importance! I also remember our agreement."

Su Mo smiled slightly and touched Fenrir's head.

"But from now on, you must also protect your sister!"

"……oh!"

After hearing Su Mo's words, Fenrir stared at him with wide eyes for some reason. After staring at him for more than ten seconds, he finally nodded and stood up.

When its slender and enchanting dragon head was raised high, Su Mo felt again that the person in front of him was not a fool with low IQ, but a giant dragon.

At this moment, the giant dragon adjusted its posture in mid-air, and then stabbed its chest with its dark green claws.

If he hadn't known that he wanted to collect blood, Su Mo almost thought he was going to commit suicide.

"Wait! Don't use too much force, just a little bit will do!"

Su Mo immediately shouted loudly.

His call was very timely.

After hearing this, Fenrir's hand immediately became much gentler, and he was afraid of the pain.

In the end, he still used his claws to poke a slight hole in his chest.

From its own point of view, it was probably just a bite from a mosquito, but to Su Mo, this little bit of crimson dragon blood was definitely not something that could be contained in a test tube.

Fortunately, he brought a double-walled glass in order to bring Fenrir mung bean soup.

At this moment, after washing with mineral water, he was immediately lifted into the air with the help of Fenrir's claws, and then he was connected to the wound near the chest. Two drops of dragon blood fell, and more than half of the glass was immediately filled with dragon blood.

Blood.

"Is that enough?"

Fenrir asked, trying to squeeze in more.

"Enough is enough!"

Su Mo quickly shouted stop.

Using such a big glass to catch the Dragon King's blood would probably make the mixed-race force jealous upon hearing this.

Fortunately, the one I brought was not a metal thermos cup, otherwise it might be directly corroded and damaged by the dragon's blood.

This was the result of Su Mo's timely stop. If Fenrir was allowed to bleed on his own, he would probably be able to bury Su Mo in a bath.

And compared to Fenrir's size, I'm afraid a bathtub of blood is nothing to him.

Seeing that Su Mo was really satisfied, Fenrir breathed a sigh of relief.

"Fortunately, it doesn't hurt, just a little itchy!"

After saying this, he bent his slender head, stuck out his tongue and licked the wound twice.

Then, the crack of a few centimeters on his chest quickly glued together under the tension of the muscles. Even the scales themselves seemed to be joined together, and there was no trace of any injury.

Controlling his own muscles is completely instinctive for him, and wanting to stop bleeding is just a thought.

Seeing this, Su Mo felt relieved.

"Remember not to tell your sister about this."

Throwing the collected dragon blood into a metal box for cryogenic preservation, Su Mo warned Fenrir.

"Ah, are you trying to lie to your sister?"

Fenrir looked uneasy.

With his respect for his sister, he really wouldn't dare to do such a thing.

"It's not deception, it's a well-intentioned concealment."

Su Mo shook his head.

He also knew Fenrir's character, so it was impossible for him to really cooperate with him to deceive Xia Mi, but some things were just a matter of another way of saying it. With Fenrir's intelligence, it was easy to deceive him.

"Your sister didn't ask, so you didn't tell her. Doesn't this count as active deception?"

He follows the path of good teaching.

"Uh... doesn't it count?"

Fenrir stared at Su Mo with wide eyes. In his eyes, any deception from his sister was probably a disobedience, and he naturally never thought of violating it like this.

Are you really not afraid of being beaten by your sister if you do this?

"Of course not!"

Su Mo said seriously.

"You didn't tell your sister how many dishes you had today, right? Is this considered cheating?"

He asked with an example.

"Not really, but I can tell my sister."

Fenrir shook his head. No matter how stupid he was, he would not think that he was deceiving his sister. If that were the case, he would probably be at a loss for words and would be sentenced to death by Ling Chi.

"Then naturally I can't count it, just like you didn't tell your sister how much you ate before."

Su Mo used strong words to poison Fenrir's simple mind.

"It's because your sister didn't ask you that she didn't tell you. In that case, even if your sister doesn't know, it's her fault, not yours!"

Su Mo originally thought that these words would be enough to convince Fenrir, but he did not expect that after hearing these words, Fenrir immediately shook his head as if on conditioned reflex.

"No! My sister can't do anything wrong!"

At first glance, it sounds like he is a great younger brother, but if you look closely at his suddenly alert eyes, you will find that rather than a heartfelt answer, this looks more like a reaction to being beaten too much by Xia Mi.

"..."

Su Mo was speechless for a moment. Isn't that guy Xia Mi's way of disciplining his younger brother a bit simple and rough?

"Then it's my fault, okay? It's not your fault anyway. Even your sister can't blame you! So you don't have to take the initiative to tell her!"

He continued to follow the lead.
To be continued...
