In Mu Mengqi's sentence of 'you don't need to use the language', the tutoring officially ended.

Back at home, Yun Lang first went to the corridor outside the living room to look at the three pots of medicinal herbs, and saw that the Burning Sun Grass had bloomed, and the Cold Spirit Grass had also grown a flower bone, and it was estimated that it would bloom tomorrow.

Flowering means that the medicinal herbs are ripe, and the Burning Sun Grass, the Cold Spirit Grass, and the rosemary obtained from You Shen can refine a furnace of 'Buyuan Dan'.

The replenishing Yuan Pill is mainly used to replenish mana and increase the continuity of the battle, which is exactly what he needs most at the moment.

The mana of the third layer of qi refining can only allow him to cast two or three 'water control duels', just like he used the water control to abolish Zheng Wei's arm, which belongs to the enhanced version of the water control duel, and he used up the mana of the dantian at once.

If the enemy is not one, but two or three, he will have to die with hatred when his mana is exhausted.

Alchemy still needs a Dan furnace, but it's too late, tomorrow happens to be the weekend, go out for a walk, and see if you can get a cheap one to use first.

With a happy mood, Yunlang reviewed the language synthesis in the living room, that is, history, geography, and politics.

These knowledge that can be learned well by memorization are not difficult for Yunlang, as long as it takes a certain amount of time to memorize.

Yun Lang's study passed for several hours, and before he knew it, it was late at night, and the creepy ghost cry sounded in his ears again.

"Boom...... Boom ......"

Yun Lang quickly put down the book, ready to figure out what the hell was going on with the 'female ghost' tonight.

Walking out of the living room, Yunlang quietly went down to the second floor.

The ghost scream came from the bathroom on the second floor, and the sound of running water was not heard, indicating that Shen Wanrong was not taking a bath.

Yun Lang quietly pushed open the door of the bathroom, and saw Shen Wanrong wearing a white dress with long hair scattered forward to cover her entire face, and a terrifying cry came from under her hair.

"Huh?"

Yun Lang sniffed the smell in the air, and just like last night, the smell of decay wafted in the air.

And last night, I also smelled this smell that I don't know where it came from, and then I saw Shen Wanrong turn into a 'female ghost' and come out.

Could it be that Shen Wanrong's transformation into a 'female ghost' really has something to do with this rotten smell.

Yun Lang made this sound, Shen Wanrong immediately spotted him, let out a scream, suddenly changed from squatting to standing, and rushed towards him, the nails on the ten fingers of his hands as sharp as daggers poked towards his neck.

"Humph!"

Yun Lang snorted coldly, grabbed Shen Wanrong's arms with a quick shot, and then quickly pushed back, grabbing her back to the room like this.

Shen Wanrong struggled desperately, letting out all kinds of terrible screams, but her hands were controlled by Yunlang to death, like a snake that had lost its fangs, and no matter how much she struggled, it was in vain.

Walking into Shen Wanrong's room, Yun Lang directly tore the sheets, first tied Shen Wanrong's hands, and then tied her to the bed.

Only then did she lift the long hair that covered her face, and sure enough, it was Shen Wanrong, but the skin on her face at this time was very strange and cyan, her expression was hideous, but her eyes were like beasts, without a trace of human feelings.

"She must have been poisoned or sick. Yun Lang guessed, and then thought of the rotten smell wafting through the bathroom.

Finding the source of the smell may solve this mystery.

Ignoring Shen Wanrong, who was struggling and screaming on the bed, Yunlang walked out of the room and walked towards the first floor.

Since the bathroom on the second floor has that smell, and the third floor also has it, it is very likely that the smell is coming up from the bottom.

Because Yunlang found that there was a gap in the connection between the sewer pipe and the floor in the bathroom, simply put, the hole in the ground was thicker than the water pipe, and the smell should be wafting up from the gap.

The bathroom on the first floor is in the utility room, and no one uses it, as soon as he walks into the utility room, Yun Lang smells a strong smell of decay, it seems that his guess is not wrong, and the smell is from here.

The source of the smell is not the bathroom, but the utility room, which wafts into the doorless bathroom through the flow of air, and then goes up to the second and third floors.

After walking around the utility room, Yunlang found his target, and there was a slight depression in the ground in the northwest corner, and a strong smell wafted from underneath.

Against the sunken ground, Yun Lang stomped his foot hard.

"Bang!"

The earth suddenly sank into a large chunk, and a deep hole appeared in Yunlang's sight, and at the same time, a strong smell of decay came to his face, and he was sucked by Yunlang.

"Ahem, ahem, ahem......"

Yun Lang coughed painfully, and at the same time, he felt dizzy, his body itched, and even had hallucinations.

"It's poisonous!, it's terrible poison!!"

Yun Lang was shocked, and quickly left the cave entrance and came outside, breathing in the fresh air, and then he felt a lot better.

It seems that this is the real reason why Shen Wanrong became a 'female ghost', and it is also the root cause of the strange deaths of other tenants.

"What's down there?" Yun Lang was curious as to why there was such a terrible poison gas.

After a little hesitation, Yunlang returned to the room, tied the wet towel to his mouth and nose, and took a flashlight to the utility room again.

If he doesn't figure out the situation underneath, he is unwilling.

After the release just now, the poisonous gas seemed to have become much less, and Yun Lang no longer hesitated, and slowly entered the ground with a flashlight.

An hour later, Yun Lang emerged from under the ground with excitement and came out with a bag of things.

Then he directly collapsed the corner of the debris, blocked the hole, and then hurriedly went back upstairs.

Yun Lang took a shower first, washed his body, and then opened what he got from the ground.

The biggest and most conspicuous is a basin-sized mushroom, this mushroom is terrible, a bit like a human face, the mushroom surface is covered with black dots, but the faint smell is very good, a bit like the smell of roses.

'Ghost Face Mushroom' is one of the two major medicinal materials for refining the 'Spiritual Pill', and the other is 'Blood Lingzhi', which happens to be there.

The 'Stored Spirit Pill' is an elixir that improves his cultivation, and it should be able to help him rise to the fourth level of Qi refining.

In this way, he can refine a furnace of 'Replenishing Yuan Pill' and a furnace of 'Accumulation Spirit Pill', it seems that luck has come, and he can't stop it.

In addition to the ghost face mushroom, there is also a golden phoenix hairpin and an inkstone, as well as a few gold bars.

The golden phoenix hairpin is a huge phoenix shape, very ornate, and it is likely to be a former royal item.

The inkstone may also have been of royal origin, and although it is made of stone, it has the shape of nine dragons on it.

For Yunlang, this represents money, so he also took it out together.

......

After dawn, Yun Lang stretched his waist, quickly got up from the bed, and washed.

Today there is a very important task, that is, to find an alchemy furnace and refine the elixir.

"Is there anyone!!"

"Yunlang, are you there??"

As soon as Yunlang opened the door, he heard Shen Wanrong's call coming from the second floor.
