"How many more layers are there in this stone staircase?" Xiao He was already impatient, and pouted and complained.

"It should be soon! We've been walking for almost half an hour, and no matter how long it is, it's time to finish it. Xiao Wang said uncertainly.

"I'm afraid you're thinking too much, we haven't even met the torch just now." Yu Feng said unceremoniously that he was also a little tired and anxious, and he couldn't walk the stone steps at the end, which was really uncomfortable.

"No, half an hour is enough to go down to a deep position, let's stop for a while." Tang Yulou stopped suddenly, his face became very serious, and he still had these expressions of chagrin.

From the beginning of his search in the mountains, he was shocked by Xia Yanru's ability, and then the other party could easily find the mechanism, he subconsciously forgot his identity, and habitually relied on Xia Yanru, but this stone step woke him up.

According to their judgment of this family burial group, the scale is indeed unprecedentedly large, but similar to this kind of large family burial group, its burial chamber will naturally not be less, and now they have only arrived at the front of the entire family burial group, even if it is the middle section, it is impossible to be so deep.

"Old Tang, what's wrong?" Seeing that Tang Yulou's face was wrong, Professor Sun also asked nervously.

"We seem to have walked for more than half an hour, but in fact, the distance we walked out was only 5 minutes at most, and we were basically standing still." Tang Yulou said affirmatively.

"Did we encounter a ghost hitting the wall?" Yu Feng was the first to react, they had encountered it before, and they were no strangers to this situation.

"It's a little different from a ghost hitting a wall." Tang Yulou shook his head, did not continue to explain how it was different, but took out a dagger and came to the wall, scraped the rock dust on the wall with the dagger, put it under his nose and smelled it.

After a while, Tang Yulou shook off the rock dust in his hand, "Sure enough, the walls on both sides should have been made of hands and feet, and the outer layer of the wall is smeared with a special powder, which will volatilize trace amounts of toxin when heated, although it is not fatal, but it will disturb the thinking and judgment of the poisoned, that is to say, as long as we are hit by this poison, no matter how we walk in this stone step, we will not be able to go to the end." ”

"Quick, put out the torch first." When Professor Sun heard this, he hurriedly commanded.

As soon as the torch was extinguished, the entire stone staircase passage instantly darkened a lot, and the person who was originally holding the torch hurriedly found a flashlight to illuminate it, and had been using the torch before, purely to save the battery consumption of the flashlight.

"Extinguishing the torch just reduces powder volatilization, we have to think of another way." Tang Yulou was a little helpless, now that the extinguishing torches is no longer useful, they have all inhaled toxins, either detoxify now, or find another way.

Xia Yanru lowered her eyes and pondered, since Tang Yulou could think of this, the toxin of the powder was indeed not powerful, but even her physique that had been transformed by special abilities and clear spring water could be tricked, which showed that this poison was not simple.

However, this is a family burial group, there was no flashlight lighting in the past, and the funeral people could only rely on torches and other heat sources to illuminate here, so wouldn't they pass through this stone step every time they went down to the tomb for burial, so how did they pass safely?

"What then? This place is really eerie, and there is a particularly bad smell, and if we go on like this, we will starve to death of thirst, if we will not die of exhaustion. Xiao Wang cried with a sad face, he had been in a hurry just now, and he didn't have the heart to pay attention to the environment of the stone staircase passage, but after stopping at this time, his senses returned to the cage, and he became a lot more sensitive to the surrounding situation.

Xiao Wang's complaining words gave Xia Yanru a hint, she actually felt that the smell here was unpleasant not long after she got down the stone steps, but this time, she had been to the tomb twice, and she was not familiar with this place, and thought that this unpleasant smell was normal, after all, it was a place where the dead were buried, and it had not been ventilated for many years, so the smell would naturally not smell good.

"Oh, it's really, a bit like the smell of urine." Yu Feng sniffed violently, the smell almost didn't send him away, and immediately covered his nose and said.

Tu Hongxing beside him rolled his eyes speechlessly, saying that it stinks, and he dares to smell it like this, and he doesn't know how this brain grows.

"Sister Xia, what should we do?" Tu Hongxing came to Xia Yanru, who was observing the wall, and asked.

Removing the light source of the flashlight from the wall, Xia Yanru turned around and comforted, "Don't worry, there will be a way." ”

In fact, after she had just checked, she already had some vague speculations, but she still needed to verify it, this was a way she was a little hesitant, but she also knew that it would definitely not work if it was consumed like this, and she didn't know when she would be able to leave the stone staircase passage.

"Director Tang, I have an idea, you can listen to it first, can you give it a try." Xia Yanru finally decided to give it a try.

"You say." Tang Yulou's eyes lit up and he hurriedly said.

"There are traces of fire on the walls on both sides, and the smell gets stronger the closer you get to the wall, so someone should have splashed urine on the wall and then roasted it with fire to detoxify it." Xia Yanru's tone was smooth and unfluctuating when she spoke, but the people who heard these words had different expressions.

"No, you can't, pouring urine in the tomb is a big disrespect to the ancestors, don't you be, right?" Xiao Wang looked incredulous.

"Boy's urine, drive away evil and avoid evil." Xia Yanru glanced at him coldly and continued to speak in a calm tone.

"There is a saying that usually evil things are negative, and the urine of children is positive, and it is not impossible to overcome yin with yang. It's just that, Xiao Xia, we didn't expect to encounter this situation beforehand, and this boy didn't prepare for urine, even if this is a way to detoxify, it can't be used. Tang Yulou sighed helplessly, he had prepared a lot of equipment that might be used in the tomb in the past, but this boy was really unprepared.

"Men who are not married are also allowed, as long as Yuanyang is not lost." Speaking of this, Xia Yanru's face was not obvious, but her tone was not as gentle as before, but there was not much change, but no one heard these slight changes.

As Xia Yanru's words fell, the scene fell into an embarrassing situation for a while, Tang Yulou touched his nose uncomfortably and took a step back, he was a married person, what Yuanyang had already lost eight lifetimes.

"Ahem, what, this difficult task depends on you young people." Professor Sun said with a dry cough.

Yu Feng looked at Xia Yanru with some uncertainty, and asked in a daze, "Sister Yanru, are you sure?" ”

Nodding, Xia Yanru is extremely sure, in fact, the boy's urine must be the most suitable, but they didn't prepare in advance, so they can only win by quantity, so many male compatriots, it should be enough.

"Okay, then it's up to the five of us." Yu Feng spread his hands and said to Tu Hongxing and the others.

"I can't." The inch-headed man said three words lightly, and the person retreated to Tang Yulou's side.

Yu Feng and the four of them didn't understand at first, why didn't he do it, and it didn't look like he was married? was just stunned for a moment, and the four of them suddenly realized that this person Yuan Yang was no longer there.

"Yes, lad." Yu Feng laughed teasingly.

"Don't talk nonsense, hurry up." Tu Hongxing gently pushed him, the detoxification was imminent, and there was no time to waste on these gossip.
