People in Zongman, start plundering the Red Dragon Emperor entry

However, in Lin Dong's opinion, there is a third use for [Protective Barrier].

Build a battlefield.

As his strength gradually increases, Lin Dong has become a true human nuclear bomb.

In order to prevent friendly forces from being accidentally injured during combat, it is very important to have the ability to quickly build a battlefield.

Apart from the [Protective Barrier], the reasons for upgrading [Bloodline of the Demon King] and [You Are All My Wings] are much simpler.

Improve the efficiency of practice.

The spiritual time house on the third underground floor has been completed, and Lin Dong will put it into practical use next.

With more time for practice, the importance of practice efficiency becomes more prominent.

Thinking of this, Lin Dong did not hesitate any longer and directly upgraded the three selected entries to gold entries.

[The entry has been successfully upgraded. Congratulations on obtaining the golden entry seal barrier.]

[The entry has been successfully upgraded. Congratulations on obtaining the golden entry, Demon King Bloodline]

[The entry has been successfully upgraded. Congratulations on obtaining the gold entry. You are all my wings.]

Three prompt sounds sounded in succession, and three upgraded entries appeared in front of Lin Dong.

The introduction of the protective barrier is basically the same as before the upgrade. The only difference is that the barrier created with the same consumption is more solid.

As for the other two entries, there have been many changes in the effect descriptions.

[Demon King Bloodline (Gold): Cultivation Speed +1500, greatly increases total mana and mana recovery speed, and completely suppresses demons with lower bloodline concentrations than itself.]

[You Are All My Wings (Gold): Greatly increases your attraction to the opposite sex. Each time you gain the affection of a member of the opposite sex, your Charm increases by 200 and your Training Speed increases by 200. This can be increased up to 12 times.]

Compared to before the upgrade, Demon Bloodline has an additional bloodline suppression effect, and You Are All My Wings has an additional effect of greatly increasing the attraction to the opposite sex.

"not bad."

A hint of satisfaction appeared in Lin Dong’s eyes.

After putting on the two upgraded items, Lin Dong walked to the corner of the material room.

In the morning, before leaving for the vampire territory, he promised Yawei to help her build a similar spiritual time house.

Practice makes perfect. Having had experience in building a time barrier once, Lin Dong was more efficient this time.

In just ten minutes, a small time barrier was formed with the material room as the center.

After injecting some time power to test the effect, Lin Dong studied the other machines in the material room.

Time passed slowly, and just as Lin Dong was fiddling with the food machine to make ice cream, a clicking sound was heard.

Lin Dong stopped what he was doing and looked at the cylindrical machine that had stopped working not far away.

"It took quite some time. I thought it would be faster."

"There was a little accident."

Yawei took Valerie out of the machine and took out a brand new report.

But just as she was about to say something, her gaze suddenly paused on Lin Dong's face.

Lin Dong: "What's wrong?"

Yawei: "Hmm...how should I put it, I suddenly feel that you are quite handsome."

Yawei stared at Lin Dong thoughtfully for two seconds, and the more she looked, the more she felt something was wrong.

"Strange, I didn't see you feeling this way twenty minutes ago. What did you do while you were gone?"

"There has been a breakthrough in strength."

Lin Dong made up an excuse casually.

If nothing unexpected happens, this should be the new effect of [You are all my wings].

However, this matter is related to the entry, and Lin Dong cannot disclose it to others at will.

"You have so many secrets."

Yawei saw through Lin Dong's thoughts and did not continue to ask questions as before.

She raised the report in her hand and waved it twice, then brought the topic back to business.

"Let me state my conclusion first. Your blood is very effective on Valeri."

"As long as there is enough blood to support her, she can even use the Holy Grail without any side effects."

"That sounds pretty good."

Lin Dong handed each of them two bowls of ice cream and then asked.

"What do you mean by accident?"

"Valerie's bloodline has evolved."

"evolution?"

"I know you're confused, but that's the result."

Yawei opened the report in her hand, turned to the second page on body composition, and pointed to a line of data.

"Normally, vampires cannot be exposed to sunlight, otherwise they will be affected to some extent."

"But after consuming your blood, Valerie's body became resistant to sunlight."

"Now, even if she stands in the sun at noon, she will only feel warm."

"That sounds pretty good."

Glancing at Valerie who was silently eating ice cream, Lin Dong thought for a moment and continued to ask.

"Aside from the change in your perception of sunlight, are there any other changes?"

"That's too much."

Yawei pointed to the rows of data on the report.

"Physical strength, soul resilience, magic power quality...basically, everything has evolved from the inside out."

"More importantly, this evolution is ongoing and continues to this day."

Speaking of this, Yawei showed a trace of emotion on her face.

This guy Lin Dong is really a monster.

In all her life, this was the first time she had seen a vampire improve its life essence by sucking blood.

"In short, this evolution is a good thing."

"If this continues, Valerie's mind and soul will evolve."

"In the future, when she evolves to her limit, she might be able to use the Holy Grail with her own strength without any side effects."

"I understand."

After Lin Dong took the report and glanced at it, he explained the matter of the time barrier to Yawei.

Because this was just discussed in the morning, Yawei has not yet figured out how to make a device to collect the power of time.

In exchange for the snack-making machine, she asked Lin Dong to help her with the first charging.

Lin Dong did not refuse this.

The time barrier in the material room is not that big.

The time power consumed by one charge is about one-tenth of the previous return to the town.

After helping Yawei complete the charging, Lin Dong left her to study the collection device of the power of time.

As for himself, he took Valerie to the third floor and chose a room for her.

But just as Lin Dong was about to leave, Valerie suddenly reached out and grabbed his sleeve.

"what happened?"

"Lin Dong, I want to suck blood."

A hint of blood red appeared in Valerie's pupils, and her eyes looked at Lin Dong with more desire.

"We have made an agreement, and we cannot go back on our word."

"Don't worry, I still remember."

Lin Dong pulled down his collar, exposing his neck.

Seeing this, Valerie, who had gradually lost her mind, hugged Lin Dong directly, stood on tiptoe and showed her fangs.

Click——!

"......it hurts."

"You really haven't learned any lesson."

Lin Dong shook his head helplessly and used his magic again to help Valerie heal her teeth.

"Use magic power to cover the teeth, and then mobilize the power of blood to strengthen them."

"You're a vampire after all, how come you can't even do something as simple as sucking blood?"

"Ugh, I forgot about that when I thought about being able to suck blood."

Valerie came back to her senses from the brink of going berserk and strengthened her teeth according to Lin Dong's instructions.

After being strengthened, the strength of Valerie's two small fangs increased sharply, and finally sucked Lin Dong's blood.

The aroma that was enough to make people intoxicated filled their mouths, and Valerie's blood-sucking urge instantly occupied her mind.

More and more.

As blood filled with rich vitality flowed into her body, Valerie's body temperature began to gradually rise.

In a trance, all the surrounding scenery disappeared from Valerie's eyes.

In the blood-red world, the only thing Valerie could see was the man in front of her who had a calm expression on his face and took out a book from somewhere and started reading it.

[Valerie is in love with you, and the entry "You Are All My Wings" is amplified.]

"Ok?"

Lin Dong, who was watching "A Director's Self-cultivation", was stunned for a moment and looked down at Valerie in front of him.

Sister, how are you?

It has been more than two months since Lin Dong obtained the wings entry, and he encountered various situations during this process.

However, this was the first time he encountered a blood-sucking person who made him infatuated and triggered the judgment of falling in love.

After throwing the half-read book back into the storage space, Lin Dong reached out and touched Valerie's head.

"Valerie, I have something more delicious than blood. Would you like to try it?"

"Better than blood?"

Valerie stopped sucking blood and stared at Lin Dong with eyes full of desire.

"Is there really such a thing?"

"Of course."

Lin Dong replied seriously.

"Your bloodsucking is essentially sucking the remaining vitality from my blood..."

"But if I want, I can directly produce high-quality life essence for you to drink."

"The essence of life..."

Valerie tilted her head and thought for two seconds.

"I want!"

"No problem, I'll satisfy you."

Lin Dong put on the stick master attribute and asked Valerie to help him make Truensu milk.

Time passes slowly.

At the same time that Lin Dong was helping Valeri replenish her energy and evolve her bloodline.
