Mo Shuwan was immediately amused. She thought to herself that when she met Wen Zuo face to face, he seemed quite serious and occasionally shy. But when they were exchanging messages, he suddenly seemed to relax.

I've already redeemed the manual, and it cost me 6,000 points, so of course I can't just throw it away. I can only grit my teeth and keep reading.

After reading it, Mo Shuwan felt much more relaxed. "It turns out that you don't need to collect all these things at once. You can take your time. And once you've exchanged them, you can eat them according to the method and order specified in the manual, and they will still have the same effect."

Mo Shuwan finally breathed a sigh of relief. As long as it was effective and made her stronger, she didn't care if the materials were a bit expensive. After all, it was an investment in herself.

She had a total of over 28,000 points left. Her plan was to spend 10,000 first and save the rest to exchange for weapons and survival items in the next world.

Despite the pain in her eyes, she exchanged for three items and also transferred another three thousand points. This was because the meridian expansion potion required a total of seven thousand points, and Mo Shuwan only had points left. She didn't know what world the next world would be, so she couldn't use any more points.

[Marrow Cleansing Potion] [Vitality Potion] [Meridian Expanding Potion]

Holding the three expensive potions, Mo Shuwan gritted her teeth and searched for the Qingyang Fruit that followed. Seeing that it only cost 500 points, she breathed a sigh of relief.

"Fortunately, it's not getting more and more expensive."

Feeling slightly relieved, Mo Shuwan put away the exchange board and carefully read through the instructions for each medicine in the first volume of the book on improving physical constitution.

The first thing she took was the Marrow Cleansing Potion. Ignoring the warning that taking the Marrow Cleansing Potion would cause excruciating pain, Mo Shuwan read the precautions several times over, took a deep breath, and went into the bathroom with the Marrow Cleansing Potion and the Vitality Potion.

Mo Shuwan quickly filled the bathtub with hot water before opening the Marrow Cleansing Potion and pouring half of it into the tub. Watching the water gradually turn green, she silently placed the remaining Marrow Cleansing Potion and Vitality Potion beside the tub, then took off her clothes and stepped into the tub.

The water mixed with the marrow-cleansing potion immediately enveloped her. Her skin, upon contact with the water, gradually felt a stinging sensation. After waiting quietly for a moment, when she felt her body begin to heat up, Mo Shuwan did not hesitate. She immediately grabbed the half-bottle of marrow-cleansing potion that was placed aside, poured it all into her mouth, and swallowed it.

According to the description in the first volume of Improving Physical Constitution, after swallowing the marrow-cleansing medicine when the body is hot, the toxins hidden in the meridians will be slowly expelled. After a person is born, he or she is contaminated with various toxins. Some of these toxins are deeply rooted, so it will be very painful when they are expelled from the body.

Mo Shuwan had experienced the pain of flesh being torn apart bit by bit, so when the pain started, she even wondered if the zombie virus would also be expelled.

But soon Mo Shuwan lost all interest in anything else, because the marrow cleansing potion finally took full effect. She was completely immersed in water containing the marrow cleansing potion. At this moment, not only did her body feel a burning pain inside, but her skin felt the same way. The intense pain gradually eroded Mo Shuwan's rationality.

Mo Shuwan bit her lower lip tightly, occasionally reaching for the vitality potion placed beside her and taking a sip to maintain her mental clarity.

It hurt so much that no words can describe it.

Mo Shuwan clenched her fists tightly. Her lower lip had been bitten until it bled, but the blood flowing into her mouth did not attract her attention at all. She felt as if her body was placed on a rolling knife rack, her flesh being cut, crushed, and reassembled inch by inch.

The excruciating pain lasted for a full hour. Mo Shuwan, who was almost numb from the pain, drank the last sip of the life-saving potion, took a deep breath, held her breath, and sank into the now dark water.

The excruciating pain continued, and Mo Shuwan tried her best to stay awake. Only after realizing that no more impurities were being expelled from her pores did she suddenly sit up.

At this moment, Mo Shuwan was completely enveloped in a layer of black filth. Except for her eyes and mouth, her nose and ears were also filled with this black filth. It should have had an extremely strong stench, but Mo Shuwan had long been numb to it after being surrounded by this stench for more than an hour.

Standing in the bathtub, Mo Shuwan, feeling much lighter than before, finally showed a happy expression.

However, after careful examination, it was discovered that the zombie virus had not been expelled and was still hidden in the body. The only difference was that all the zombie virus was concentrated in the abdomen, instead of circulating freely in the bloodstream as before. This was why Mo Shuwan was able to accurately detect the zombie virus.

"Spending so many points was definitely worth it." With a soft sigh, Mo Shuwan picked up the meridian-expanding potion and poured the whole bottle down her throat.

The reason I didn't immediately take a shower and drain the blackened sewage from the bathtub was because the manual instructed that after drinking the meridian-expanding potion, I needed to lie down again in water with added marrow-cleansing potion. Although the water was already black and looked disgusting, its effects were still there.

After drinking the meridian-expanding potion, Mo Shuwan carefully examined her body and found that nothing seemed to have changed... However, she still followed the instructions in the manual and immediately lay down in the bathtub, burying her face in the dirty water.

Visible black filth emanated from Mo Shuwan's pores, quickly filling the entire bathtub. By the time she sat up, the bathtub was completely dry.

The overwhelming stench assaulted her nostrils, so Mo Shuwan quickly pressed the drain button, got out of the bathtub, and took a shower. It took her a full hour to clean herself up.

Mo Shuwan walked out of the bathroom in clean and comfortable pajamas, opened her phone to send a message to Wen Zuo, but to her surprise, Wen Zuo's message popped up as soon as the screen lit up.

Wen Zuo: Have you come out yet?

Wen Zuo didn't have as many points as Mo Shuwan, so he only exchanged one Marrow Cleansing Potion and one Vitality Potion. Therefore, he recovered faster than Mo Shuwan. At this time, he was already lying in bed staring at his phone, waiting for Mo Shuwan to recover.

Mo Shuwan: I'm out. Although I don't feel any increase in strength, my body feels much lighter. I now suspect that I can run 100 meters in a few seconds.

Wen Zuo: I feel the same way. Once I've collected all the items needed to improve my physique in the first volume, I should become very strong.

Mo Shuwan: So we need to work even harder in the next world.

Mo Shuwan and Wen Zuo chatted via text for a while before lying down to rest. Both of them were exhausted during their time in the vampire world, especially in the last few days when they barely had a chance to close their eyes. Now that their bodies and minds were relaxed, they fell asleep almost instantly.

...

Inside the bus station, a tall, muscular man stood in a corner, holding his phone and looking menacing. "I've said before that this has nothing to do with my family. If you dare to touch my family, I'll release the information even if it kills me!"
