"It is too difficult to completely wipe out the true qi in his body, and it is very likely to cause the true qi to self-destruct."

"Don't say that I'm exhausted of my spiritual power now, even if I have full spiritual power now, I'm afraid I don't dare to act rashly." Qin Heng looked at Zhang Haochen with his brows furrowed.

This one is too difficult, even he, an old monster, is stumped.

Qin Heng's cultivation is still too bad, if he is now a cultivation at the fifth or sixth level of Qi cultivation, this bit of true qi, he can instantly destroy it before it explodes, so he doesn't have to worry about it exploding and hurting people like he does now.

"There's not much going on, I must consume the true qi in his bones as soon as possible." Qin Heng hurriedly thought.

"Even if there is no good way to do it in the main gate of the spell, even if there is, it requires a high level of cultivation before it can be cast."

If it had been changed, he would not have touched this bloodthirsty spell before the demon outer path would only use it, but now...... This is no longer the case.

If you are still stubborn, you will only let Zhang Haochen die in front of you.

The face is stubborn, and he lives and dies with his brother. Qin Heng didn't hesitate at all, he had already chosen to use the Demon Gate Technique.

"Don't say that my heart is not as vicious as the people in the Demon Gate, if I can save Zhang Haochen, even if I sell my soul to the devil, what if I sell my soul?" Qin Heng thought disappreciably.

Qin Heng knew a lot about the spell exercises of the Bloodthirsty Gate, but he had never studied them, and at this time, he carefully remembered some of the small spells of the Bloodthirsty Spell Exercises stored in his brain.

"Yes, there is a technique in the bloodthirsty mantra that sucks up people's blood, which seems to be called ...... It's called the Blood Exchange Spell. Qin Heng's eyes lit up, and he muttered to himself with some joy.

The Blood Exchange Spell is used to provide disciples in the Bloodthirsty Sect for cultivation, even if the cultivation is very low, it can be used, mainly to ban the blood in a living being's body, and then change it to his own body, and directly devour the essence of the other party.

Devouring the other party's blood so quickly, it is also extremely fast to improve cultivation, but it will also swallow the other party's emotions, so it is easy for people who use this method to swallow some resentful blood emotions, and over time, they will be controlled by this emotion.

In the Tian Yuan Continent, if a person who cultivates the Bloodthirsty Sect can't control his emotions in the end, it is very likely that he will become a bloodthirsty killing demon who is not a human or a ghost, endangering the common people, and everyone will be punished.

"Changing blood, this reminds me that I can use my divine sense to guide my true qi into the blood, and then use this spell to exchange it directly on my own body." Qin Heng had a plan in his heart.

As long as the true qi enters his body, Qin Heng will use the True Cultivation Law to refine and suppress, and at that time, as long as the Demon Decision is broken, that is, Zhang Haochen will be transfused with blood within half a day, and he will not have an accident.

"However, in this way, if I don't operate well, I may be blown up by that violent true qi and die." Qin Heng looked at it in his heart, and finally smiled and was relieved.

Zhang Haochen can die for himself, can't he risk life and death for Zhang Haochen?

"Since you regard me as a brother, then I will not fail you." Qin Heng looked at his good buddy Zhang Haochen with tender eyes, and he strengthened the idea in his heart.

"Let's get started, I need to prepare something." Qin Heng walked towards the door.

He also needs to prepare some necessary supplies, such as some sterilized transparent plastic bags for exchange transfusion, which are not difficult to find in the hospital.

Qin Heng walked out of the door and saw the four bodyguards frantically swallowing clouds and spitting mist, hoping that the spicy tobacco could make the heads that had not been put to sleep clearer.

"Brother Qin." Seeing Qin Heng come out, they nodded respectfully.

"Get me some bags for blood transfusions, and a sharp scalpel, and a couple of A4 sheets of paper, and a brush." Qin Heng thought about it and commanded.

"Huh?" The four of them were all taken aback, they were a little puzzled why Qin Heng needed these things.

"Don't 'ah', go ahead, I'll use it in a hurry." By the way, you leave someone to guard this room, no one is allowed to come in, and you can act violently if necessary. Qin Heng commanded two more times, then turned around and went into the ward again.

The four bodyguards glanced at each other, not knowing what to do, but one of them suddenly said: "Brother Qin has a great favor to our Dilong Company, and Sister Mei said that we must obey his orders, let's hurry up and find it." ”

"Yes, although these things are not difficult to find, it is not an easy thing to ask for, Brother Qin is waiting to use them, I will go with him to find a scalpel and a blood transfusion bag, you go out to the stationery store to buy A4 paper and brushes, as for you, buddy, just continue to take care of here."

The four of them quickly assigned their work and took action one after another.

Speaking of Qin Heng again, he entered the ward, and without the slightest hesitation, he began to sit cross-legged on the ground, preparing to close his eyes and meditate to recover the spiritual power in his body.

"It's really thin enough, but if the spiritual power can be restored, the grasp will be greater." Qin Heng thought in his heart, and he quickly swallowed the aura around him.

"There's a lot of blood here, and there's a lot of resentment in the hospital, so if I use it to practice the Bloodthirsty Spell, I'm afraid I'll be able to regain my full spiritual power soon...... However, if you do so, you will be on the path of the bloodthirsty devil. Qin Heng wasn't too sure about whether he could control the crazy emotions of the Bloodthirsty Curse, so he decided.

You can't use such a spell to devour blood until the moment you need to.

"Close your eyes and refresh your mind and start refining." Qin Heng dissipated his cranky thoughts and began to meditate carefully......

"Knock knock."

Qin Heng felt the passage of time, and after he had walked a big week completely, there was a knock on the door of the ward.

"Come in." Qin Heng stood up from the beginning, and he shouted at the door.

A bodyguard walked in, the black hair bangs on his forehead were already wet with beads of sweat, and when he saw Qin Heng, he hurriedly put the brush scalpel in his hand and a large bag of plastic bags.

Qin Heng opened the black plastic bag, which contained twenty or thirty packs of two hundred milliliters of blood packets and transparent plastic bags, he couldn't help but click on it, it was obviously enough.

"Is that okay?" The bodyguard wiped the sweat from his forehead and asked.

"It's okay, you go out, no matter who disturbs you, you are not allowed to come in, you can start resting in batches, and I don't have to call me if I don't come out inside." Qin Heng gave an order to the bodyguard and let him go out.

"Blood exchange is a big deal, and it is necessary to control the state of Zhang Haochen when there is no blood in his body, otherwise he will die the moment the blood is drained. I'd better draw a few bloodthirsty talismans for the Bloodthirsty Gate first. ”

Qin Heng recalled the magic inheritance in the bloodthirsty door in his mind, sat cross-legged on the ground, opened a transparent plastic blood bag, and then quickly swiped his finger with a scalpel.

The scalpel was obviously extremely sharp, and the flesh was like half of a piece of paper, and a slender cut was made in an instant.

"Tick tock!"

A large amount of blood fell into the blood plastic bag, and it was half full in an instant.

Qin Heng also used a scalpel to cut a huge piece of A4 paper into the shape of seven or eight long rune papers, took out one of them, put down the scalpel, picked up the brush and stained it in the blood bag.

The brush was dyed red, and Qin Heng's eyes flashed, and he quickly sketched on the long A4 paper.

"Control."

Quickly wrote a control character on the paper, and he quickly wrote a subtle 'control' character in the mysterious Tianyuan Continent font.

"You also need to absorb some resentment into it, so that this rune paper will have energy." Qin Heng thought about it, he didn't have the support of spiritual power now, he could only use the grievances of the dead in the hospital, which would make this rune paper really generate energy.

"The complainer is the lead, the rune paper is the home, condensation!" Qin Heng muttered in his mouth, put down the brush with his right hand, and stood up as a sword finger and shook suddenly.

Qin Heng's spell quickly reacted.

"Whoa!"

A jet-black aura pierced through the walls, like disembodied ghosts......
