Zheng Qian understood.

The reason why the old lady is like this is completely due to the resentful spirit of the Taiji snake.

And just now, the old lady was about to bite Zheng Gan, but she sensed the breath of the little black girl, the latter's cultivation has been hundreds of years, comparable to when it was at its peak, the two are compared, which is stronger and which is weaker, and how dare it take it back?

"Doctor Zheng, can my wife's illness be cured?" Chen Cang asked again.

Zheng Qian reacted at this time, and said after a moment: "It can be cured, but the process is complicated, I'll write you a prescription, Old Chen, you go and get the medicine together now, and then find me a super large vat, a large vat that can put the old lady in, and it is filled with ice cubes!"

"Okay!" Chen Cang did not hesitate, took Zheng Qian's prescription, and went directly.

Zheng Qian nodded, didn't speak, just communicated with the little black girl.

"Hehe, it's a lot of luck now!" said the little black girl happily.

"Is this Tai Chi snake?" Zheng Qian was a little puzzled.

The little black girl said angrily: "You know a fart, this girl's cultivation has encountered a bottleneck, and it is difficult to break through in a short period of time, so I can only wait for the opportunity and wait for the arrival of the heart demon tribulation, but in that case, there are too many uncertain factors, everything has to depend on creation, a lot of monsters, you can't wait for the heart demon tribulation for a lifetime, if you wait for it to come, and get through, it is a qualitative change from beginning to end, good luck, maybe you can still be ranked in the immortal class!"

Zheng Qian's face was speechless, "What does this have to do with the resentful spirit of this Taiji snake?"

"Of course it matters!" the little brunette waved her little fists. This Tai Chi Snake was a failure to cross the heart demon tribulation, seriously injured, and the cultivation was completely wasted, otherwise, it would not be possible to be caught by a mortal, although its cultivation is gone, but hundreds of years of cultivation obsession is still there, the heart demon tribulation, the exercise is the heart obsession, I also have hundreds of years of cultivation, the strength is passing, but the obsession is still lacking, if you can absorb the obsession of this Tai Chi snake, I think, the heart demon tribulation will come soon, and when the time comes, the contract we concluded will be able to be lifted!"

Zheng Qian's heart was empty, he didn't know why, when he heard this, he actually had a feeling of emptiness in his heart, and he said after a while: "Is the heart demon tribulation very powerful?"

I don't know if the little black girl didn't feel it, but she still said in an excited voice: "Of course, this is the most anticipated and feared calamity of all monsters, carp Jackie Chan, jumping dragon gate is also a demon calamity, as long as you can get through, it will soar into the sky, but, 99% of them end in failure!"

Zheng Qian's heart darkened, and he hesitated, "Can't you choose not to go?"

The little black girl was also silent, and after a while, her voice came, a rhetorical question.

"Is it just willing to be mediocre? Even if there is only one percent chance, I will fight, even if I know that the final result will be failure, but if I choose to give up, I will regret it for a lifetime, I don't want to regret it, even if it is really destroyed under the demon calamity, I don't want to be so ordinary and mediocre for a lifetime!"

Zheng Qian froze suddenly, his words were blocked in his throat, and he couldn't say anything.

At this time, Mr. Chen's nanny came over, "Doctor Zheng, you have made the things that Mr. Chen prepared and are putting them outside the hospital!"

Zheng Qian also sighed and said, "Go, I'll always stand behind you!"

The little black girl was also silent, and whispered in her heart: "Thank you!"

The huge three-meter-tall tank in the courtyard has been set up, and it is full of ice cubes.

The reason why I chose to put ice is because the snake is a cold-blooded animal and does not like low temperatures, in this case, the resentful spirit of the Taiji snake that has lost its cultivation will be limited to a large extent, and the little black girl is different, she still has hundreds of years of Taoism, resisting the cold of this area, it is simply a piece of cake, and the probability of success is naturally much greater.

According to Zheng Gan's instructions, all the irrelevant people withdrew, and Chen Cang also left, and went to boil medicine according to Zheng Gan's instructions.

When Zheng Qian just put the old lady into the vat full of ice cubes, the old lady resisted violently, constantly struggling, and her mouth was still roaring.

But Zheng Qian didn't care about it, he had already sealed the old lady's bloodline with a silver needle, and this roaring sound was just a resentful spirit from the Taiji Snake.

Time passed slowly, the old lady's roar became lower and lower, and finally, at this moment, in Zheng Qian's pocket, a black essence flashed away, and instantly rushed into the big vat, and the little black girl showed a reduced version of the body, firmly wrapped around the old lady's body.

Suddenly, the old lady, who was originally hoarse, saw that the little black girl was like a mouse meeting a cat, and she resisted violently again.

"Bang!"

"Boom!"

The vat full of ice was banging.

However, Zheng Qian is not worried, if the little black girl can't even deal with a mere resentful spirit, let alone the heart demon tribulation.

It didn't take long for the old lady's movements to slowly become smaller, and finally she completely lost her resistance.

Zheng Qian sat on the side and watched, he clearly saw that in the sky above the big vat, a pitch-black phantom was trying to devour a half-black and half-white phantom, one bite, one bite.

When the two phantoms merged into one, the originally cloudless clear sky suddenly exploded with a thunderclap.

Zheng Qian stood up and squinted at the big vat, but he pinched a cold sweat for the little black girl in his heart.

The process of devouring is not long, but the waiting process is extremely long.

Two hours passed, and the little black girl turned into a black light and rushed into Zheng Qian's pocket.

"I'll rest for a while recently, and when I wake up, it's time for the Demon Tribulation to come......"

Zheng Qian was not idle, and hurriedly called Chen Cang to come in, smashed the vat, and hugged the old lady inside, the old lady's body at this moment has returned to normal, and it is no longer in that swollen state.

"Quick, bring up the medicine you just boiled and feed it!"

Zheng Qian quickly commanded.

A few people were in a hurry,. It's done after all.

"Wow!"

There was a strange sound in the old lady's stomach, and soon, the feces and urine were all down.

The other helpers suddenly ran out of ideas, but Zheng Qian breathed a sigh of relief, "It's okay, you go and wash the old lady, and I'll prepare for the next treatment!"

After finishing the old lady's work, Chen Cang's face also looked much better, the resentful spirit of the Taiji snake was eliminated, and the gray aura shrouded in the entire villa disappeared, and the gray aura that originally shrouded Chen Cang's face and the nanny's face also disappeared.

Chen Cang looked at Zheng Qian with a grateful face, "Mr. Zheng, thank you so much today, I have just checked the pulse of my insider, the pulse is stable, everything is normal, thank you so much!"

Zheng Qian smiled politely, "You're welcome, just raise your hands!"

Chen Cang said very respectfully: "The old man is very curious, I have never understood what is the situation of my wife? Also, Mr. Zheng, what method did you use to cure it? Can you say it to open the eyes of the old man?"
