After thinking for a full minute, Zhang Yuan looked at Hei Tao beside him and said:

"Spades, this seems to be another moment in my life that will change my destiny.

I'm a little panicked now. I don't know how to choose. What do you think?

Should I join the Yin Gui Men or reach this cooperation? "

Heitao looked at Hou Tiannan, then at Zhang Yuan, and without saying a word, he took the bamboo slip from Hou Tiannan and handed it to Zhang Yuan.

Then he took a step back, keeping a distance from Zhang Yuan and Hou Tiannan.

That means letting Zhang Yuan accept the Qing Nang Book, and at the same time telling Hou Tiannan that now I trust you enough and will no longer suspect that you will assassinate my doctor Zhang.

Hou Tiannan looked at Heitao's two simple actions and was greatly impressed. He couldn't help but sigh that Heitao, the female killer, really had some emotional intelligence.

No wonder the Li family would spend a huge sum of money to redeem her from the killer organization.

Hou Tiannan immediately applauded, gave Heitao a thumbs up and said:

"Heitao, you really are the golden personal assistant of Divine Doctor Zhang. Divine Doctor Zhang is blessed to have a woman like you."

Zhang Yuan burst into laughter and said:

"Master Hou, since my beloved woman has made the decision for me, I will never regret it, don't worry.

From now on, I will do everything that the Yin Gui Men asks me to do without hesitation, and I promise you that I will report to you immediately any inside information I can get inside District 7.

I am so happy to be able to work for the Yin Gui Men. When will you give me another copy of the Qing Nang Book? This thing is really good. I just took a few glances at it and I am a little addicted to it. I really like it. When can you give me some more? "

Seeing Zhang Yuan's true nature revealed, Hou Tiannan laughed once again:

"Doctor Zhang, don't worry. As long as I, Hou Tiannan, am here, I will definitely let you learn the Qing Nang Book from beginning to end. The next time should be soon. I will send the book to you in about three to five days. But now that I have expressed my gratitude, Doctor Zhang, should you also express your gratitude to me?

With your strength, you should be able to see some of my situation."

Zhang Yuan handed the Qing Nang Book to Heitao and said:

"Mr. Hou, so that's your intention. OK, I understand. I can cure your old waist and leg injuries in just three days.

In the next three days, you must find the right opportunity to come to me every day. I will give you treatment for about 10 to 20 minutes each time.

In three days your waist will be able to straighten up, and your legs and feet will be better than they are now.

In this way, Mr. Hou's fighting power will surely improve by leaps and bounds. I would like to congratulate you in advance on your great increase in strength."

Hou Tiannan was impressed by Zhang Yuan's words from the bottom of his heart. This guy was indeed a genius in traditional Chinese medicine. He didn't ask him to feel his pulse, nor did he tell him any purpose. He knew clearly that he had an old illness just by communicating with him, and he also knew that his most painful parts were his waist and legs.

Awesome, really awesome! If there is such a miracle doctor inside our Yin Gui Men, then countless strong men in our Yin Gui Men can definitely be saved.

If those strong men were still alive, it would be much easier for the Yin Gui Men to do things in this land. Unfortunately, there are no such geniuses in the Yin Gui Men.

But then again, this is perfectly normal. There have only been a few true miracle doctors throughout history, otherwise Hua Tuo, Bian Que, Zhang Zhongjing and others would not have been so famous in history and praised by generation after generation.

Genius is something you can only encounter by chance, and although Zhang Yuan is not that famous yet,

But it is basically certain that this person is definitely a genius who can be compared with the ancient great doctors Bian Que and Hua Tuo. If he were to learn truly powerful medical skills,

The medical skills he demonstrated were definitely no worse than those of the ancient miracle doctors, and such a miracle doctor was loyal to our Yin Guimen.

No, I can secretly treat the masters of my Yin Guimen and sneak into the 7th District to gather information for my Yin Guimen. What a wonderful thing is this?

With the help of such a miracle doctor, the Yin Gui Men will surely be able to grow rapidly in this land and accomplish great deeds in the future. And I, Hou Tiannan, will be the one who has made the greatest contribution...

Thinking of this, Hou Tiannan couldn't help but raise the corners of his mouth. He was really happy.

............

Next, Zhang Yuan brought Hou Tiannan to the study room where they usually boiled medicine and rested.

Here, Zhang Yuan first took Hou Tiannan's pulse to find the root cause of his illness, and then found the silver needle and said to Hou Tiannan:

"Sit down first, I will clear the blocked meridians in your back.

Since it is a silver needle, it will be very painful, you have to bear it, after all, your back injury was there 20 years ago, but it has never been healed.

Over time, it became a chronic disease. Even though I have a high level of attainment in acupuncture, the pain is unavoidable, and it can even make you faint.”

Hou Tiannan said resolutely:

"Doctor Zhang, please feel free to treat me. If I, Hou, say anything, I will lose."

Zhang Yuan smiled and said:

"I feel relieved with your words, Mr. Hou."

After saying that, Zhang Yuan asked Hei Tao to guard the door.

Zhang Yuan took out the silver needles and started the treatment. After more than 10 needles were inserted into the relevant parts,

Zhang Yuan took out a long silver needle and inserted it directly into the Dazhui point, and then went all the way down to clear the meridians.

Hou Tiannan grimaced in pain and his whole body was shaking.

However, Hou Tiannan still persisted and did not make any sound. Finally, he could not hold on any longer and began to hum.

Seeing Hou Tiannan in such a state, Hei Tao picked up a towel that Zhang Yuan had used to wipe his feet and stuffed it into Hou Tiannan's mouth.

Hou Tiannan immediately nodded to Heitao with great gratitude and began to bite the towel frantically.

This trick is quite effective. Biting the towel hard continuously and releasing the pain on the towel made Hou Tiannan feel a lot more comfortable, but the piercing pain was always with him.

............

This treatment lasted about 10 minutes. After 10 minutes, all of Hou Tiannan's clothes were soaked with sweat.

After Zhang Yuan took away the needle, Hou Tiannan spat out a mouthful of black blood on the spot.

After spitting out blood, Zhang Yuan handed Hou Tiannan a glass of water and said with a smile:

"Mr. Hou, you are indeed a hero.

I really admire you for being able to endure such pain without struggling or moving. If it were me, I would have fainted from the pain long ago."

Hou Tiannan was praised by Zhang Yuan and waved his hand modestly, saying:

"Dr. Zhang, you really flatter me too much.

I, Hou, was so embarrassed to endure this little pain, which is really not worthy of praise. I have to say that you, Doctor Zhang, are a man of extraordinary medical skills. You only gave me preliminary treatment with acupuncture, and I felt my waist and back were so relaxed.

This kind of warmth is something I have never felt before, and after spitting out a mouthful of blood, my entire chest seemed to open up."

Zhang Yuan smiled and said:

"Of course, my acupuncture technique is perfectly compatible with the meridians of the human body.

I am not bragging about this. Even an old Chinese medicine practitioner in his eighties or nineties may not be able to catch up with me.”

Hou Tiannan laughed again:

"Dr. Zhang, you are really not modest at all, but I like your personality.

What treatment do I need next?"

Zhang Yuan waved his hand and said:

"For now, let's just do acupuncture on your back. The meridians in your legs are more complicated than those in your back. This is the limit of your pain tolerance today.

If I continue to treat your leg disease, I'm afraid you'll faint. I'm also worried that your body's vitality won't be able to withstand such a torment.

Wait until tomorrow. Find another opportunity to come to me tomorrow. I will treat your old leg disease. By then, your back should be able to straighten up a part.

And you will feel very comfortable. And when you come tomorrow, I will prepare a decoction for you to regulate your blood and qi, so that you can feel better and recover from your injuries better."

Hou Tiannan was extremely grateful and bowed to Zhang Yuan on the spot, saying:

"Dr. Zhang, it's all thanks to you.

If you need my help in the future, just let me know. I, Hou Tiannan, will do whatever I can to help you."

Zhang Yuan said politely:

"Mr. Hou, from now on we are good friends. You don't have to be so polite to me. You know that what I am most interested in now is the Qing Nang Book. You must do your best to get the next volume for me. I am very interested in this thing.

After I have completely mastered the Qing Nang Book, I promise you that I will be the first to extend your life, so that you will not only live longer, but also become stronger and stronger. Even if I join the Yin Gui Men, we will always be best friends..."

Hou Tiannan was really happy with what Zhang Yuan said, and he kept assuring:

"Since you said that, Doctor Zhang, we are now friends. No problem, I will get you the second volume as soon as possible. Let's exchange contact information so that we can communicate in a timely manner in the future."

Zhang Yuan immediately said:

"Yes, yes, we must leave each other contact information."

After the two added each other as friends and added each other's phone numbers, Hou Tiannan waved to Zhang Yuan, and a black shadow disappeared into the night.

As fast as a ghost.

Watching Hou Tiannan disappear, Zhang Yuan let out a long sigh.

Then he took Spade back to his room.

Whispered to Spade:

"Heitao, through close contact, do you think you have any confidence in defeating Hou Tiannan?"
