"Give it to him. The witch said softly.

Although it was only two short words, the tone was not a consultation, but an order.

If nothing else, it stems from Yun Fan's sentence "Time may be some", for Granny Hai, time is life.

Even if Gu Bohan could wait, the witch didn't want to wait.

Gu Bohan was silent for a moment, but he didn't dare to resist the witch's order, and very reluctantly handed the transparent vial in his hand to Yun Fan.

Taking the True Yang Blood in Gu Bohan's hand, thinking that this was actually refined from the essence blood on Wan Zai's body, Yun Fan couldn't help but feel a lot of emotion in his heart.

In less than half a day, he and Wan Tsai met again, and it was in this form......

Looking at the True Yang Blood in his hand in the bottle, Yun Fan was not sure enough to cure Granny Hai, but if he didn't say so, how could Gu Bohan easily hand over the True Yang Blood to him.

Yun Fan gently opened the mouth of the bottle, only to feel an incomparably pure yang energy mixed with the sweetness of blood surging into his nose.

Is this true yang blood......

Staring at the rich blood droplets in the bottle, Yun Fan's source qi instantly gushed out, firmly enveloping the true yang blood.

In the sea of hearts, the qi contained in the true yang blood also emerged.

The incomparably pure fire element loomed under the ring of blood droplets, and Yun Fan was amazed in his heart by the wonderfulness of Gu Bohan's refining of this method.

It is impossible to condense such a rich fire element in human blood for a long time, and it is even more difficult to do this if it is only combined with the blood of the human body, even if it is essence blood, it is not possible, but I don't know what kind of secret method Gu Bohan used, she can successfully do this, no wonder she named it True Yang Blood, and also regarded it as a treasure.

The breath in the true yang blood also became active under the guidance of Yun Fan's source qi, and at this moment, Yun Fan's fingers touched Granny Hai's withered wrist again.

At this time, the source qi with the breath of true yang blood flowed to Granny Hai's dantian again.

It was not the same as the last touch, with the assistance of True Yang Blood, when the source qi once again encountered the rock-solid shackles, it really changed.

Like boiling water dripping ice, the huge and sturdy shackles showed a hint of melting after being touched by the true yang blood, but unfortunately the melting range was too small, compared to the entire shackles, it could even be said to be a drop in the bucket.

But this is a world of difference from the previous touch that only used source qi, at least Yun Fan already knew in his heart at this time that True Yang Blood did have a certain healing effect on Granny Hai's illness.

And just when Yun Fan's mind was in a hurry, a trace of alarm flashed in his heart.

Yun Fan looked intently, but found that it was the location that had been melted by the True Yang Blood before, and it was slowly healing at this time, not only that, but even because of the stimulation of the True Yang Blood, the shackles reacted instead, and began to slowly expand outward.

It turns out that this shackle will grow bigger on its own...... Therefore, the treatment of Granny Hai's illness by True Yang Blood is only temporary, and it will have the opposite effect later, exacerbating the deterioration of Granny Hai's injury......

After receiving this information that shocked him, Yun Fan gasped, and then slowly withdrew his fingers.

"You can't use True Yang Blood for Granny Hai anymore......" Yun Fan groaned slightly and said slowly.

"Why?" the witch asked softly.

Even Granny Hai on the bed glanced at Yun Fan intently when she heard this, and she didn't seem to know why Yun Fan said this.

"True Yang Blood not only can't heal Granny Hai's injuries, but it will aggravate her condition......" Yun Fan replied.

"You're talking nonsense!" Gu Bohan's eyes widened, and he scolded sharply, "The True Yang Blood is specially refined by me for Granny Hai's illness, and you actually not only say that it is ineffective, but also slander that it will aggravate Granny Hai's condition, how can I not know whether the True Yang Blood is effective or not? You mean that I want to harm Granny Hai? It's really ill-intentioned, what do you want?"

Seeing that Gu Bohan was excited, the witch was easily disturbed by Yun Fan's words, so she frowned slightly, intending to listen to Yun Fan's explanation.

"I didn't say you were going to harm Granny Hai...... I'm just saying that True Yang Blood will aggravate Granny Hai's injuries......" Although Gu Bohan was emotional, Yun Fan looked calm and asked slowly, "Then let me ask you, every time you use True Yang Blood to heal Granny Hai, is the initial effect extremely obvious, but it won't be long before the symptoms will come back, and even worsen......

Thinking of everything that the source qi had sensed just now, Yun Fan already knew that whether Gu Bohan was intentional or unintentional, her true yang blood did play the opposite role.

As soon as these words came out, Gu Bohan's eyes widened, even if the witch and Granny Hai didn't know, but she knew it very well in her heart, because Yun Fan's words were true.

"And as you continue to use True Yang Blood, you will find that the effect of True Yang Blood is becoming less and less obvious, but the speed at which the disease comes back is getting faster and faster......"

When Yun Fan said this, a flash of surprise flashed in the witch's eyes, because a month ago, Gu Bohan had indeed said to himself that Granny Hai's body had begun to resist the true yang blood.

"Impossible!" Gu Bohan retorted, "I have analyzed Granny Hai's blood, and it can perfectly fuse with the juice of Bingyi Grass, which is enough to show that Granny Hai's condition is caused by the invasion of cold poison, how can the True Yang Blood I carefully refine be ineffective against cold poison...... In addition, the human body will be resistant to the same medicine, so it is inevitable that the efficacy of the True Yang Blood will be reduced......

"My master once taught me a sentence, that is, 'the heat is extremely cold, and the cold is extremely hot', and extreme cold and extreme inflammation are indistinguishable from the human body......"

Thinking of the principles of medicine that Yuan Ping had inadvertently taught him, combined with Granny Hai's illness at this time, Yun Fan thought of a possibility like an initiation, "If Granny Hai's initial injury is not cold poison, but flame poison...... The extreme flame poison caused Granny Hai's blood to be chaotic, showing that she was in a state of cold poison, so when the True Yang Blood was used to treat Granny Hai, it actually contributed to the situation of flame poison......

"So it's not that the True Yang Blood is invalid...... It's the opposite direction from the beginning......" Yun Fan analyzed.

"It's extremely cold...... The cold is extremely hot...... The heat is extremely cold...... The cold is extremely hot, ......" Gu Bohan kept repeating these two sentences of Yuan Ping, and the shock in his heart was even more indescribable.

"Flame ......"

At this time, the witch suddenly spoke, and her tone was even more surprised,

"Aunt Hai used to ...... I was indeed injured by the Nine Shadows Heart Flame......"
