In fact, Lin Mengya was not far away, but due to face, Du Yangfeng didn't mean to call directly.

Listen to Cairu's meaning, I'm afraid the poison gate doesn't have the intention to cooperate with them.

It's no wonder that the previous two doors fought like a black eyed chicken. It's reasonable for people to ignore them for a while.

Du Yangfeng didn't continue to pester, but said with a smile: "in that case, it's inconvenient for us to disturb. We just have some things with a sincere heart. We hope to discuss with the palace master and ask my sister to tell me my sincerity."

Cairu nodded modestly, advancing and retreating properly.

"It's natural. If there are countless, I'll leave first."

She turned around and caught up with the people in the poison gate with light steps.

Behind him, Du Yangfeng looked at each other with a smile, but turned around and his face was a little gloomy.

"Du Da's love, which has never been disadvantageous, has also lost?"

A woman's voice with a little sarcasm came.

Then, behind Du Yangfeng came a woman with a graceful body and a beautiful face.

As soon as Du Yangfeng saw her, a bright smile hung on his face, but there was a touch of fear in the bottom of his eyes.

"What? Jealous?"

He asked in a greasy voice, but the woman opposite just sneered at her.

"I don't like you. The person I like must be a good man in this world."

Du Yangfeng was a little unhappy.

However, Chi Nu's identity was unusual, and he did not dare to offend easily.

"It seems that I can't get into miss Chinu's eyes. Only a man like elder martial brother Shen is the first choice in your heart?"

Chinu looked at him, but just smiled contemptuously.

"My eyes are different from Cao Yue's. people like elder martial brother Shen are like flowers in the water and the moon in the mirror. They can see that they can't eat. In the end, they can only suffer by themselves."

She glanced at her side and found Cao Yue eavesdropping.

I don't like her timid behavior, but she is still smart and doesn't hate herself.

Du Yangfeng saw that Chi Nu was not fooled, but he didn't continue to dig a hole.

But with a smile, he returned to Shen Bingqing and his party.

"Elder martial brother Shen, the result is not very good. The little beauty of poison sect seems to resist our approach."

Shen Bingqing didn't speak, but calmly looked at the dense forest where the poison door was located.

"No hurry."

Du Yangfeng smiled and nodded. Although he was the leader on the surface, in fact, Shen Bingqing made every important decision in the end.

He is not willing to be suppressed by the other party. However, even if he refuses to accept some things, there is no better way.

This time, they continued to return to the camp in the forest.

Just arrived here, Zhu Yan and his brother sent back the news.

"Has anyone been unable to control it?"

After listening to the visitor, the corners of her mouth rose.

This time, in addition to the external assistance of the poison gate, those enemies who were really threatening to her finally showed signs.

Today, when they went down the mountain, someone slipped into the mountain quietly.

Unfortunately, what they don't know is that with Xiaobai and Xiaohu, the movements in the mountains can't hide from them.

In the next five days, whether they or Zhu Yan, there will be a hard battle to fight.

Relying on the advantages she had accumulated before, she sent Zhu Yan a batch of poisons that could be applied to weapons.

Others can make traps and so on.

In a word, there are a large number of troops, which are enough to arm them. They are a small team, but their combat effectiveness is very fierce.

She estimated the time. The people of Zhenlong hall and Hanya guard will also enter the mountain in these days.

In short, Yanxia mountain is completely lively.

Having arranged all this, she began to pack up her things.

She wants to go to Tiankeng again. This time, she not only wants to fulfill her promise, but also wants to find out why the doctor chose here.

In addition to Yu, there will be Bai Su with her.

But this time, her man will choose to hide in the dark and become her most powerful trump card.

This night, everyone is reluctant to go to sleep.

At dawn, she took Bai Su and set out quietly.

It was quiet in the woods. Without disturbing anyone, they came to the side of the Tiankeng.

The poison fog attacked again, but she was ready.

He took out a huge blanket from his baggage and wrapped them up easily.

The air was filled with the smell of dust.

Compared with the previous toxic fog, the concentration decreased a lot, but the dust particles increased significantly.

Fortunately, most of the black fog will fall back, otherwise they will choke to death.

"Master, can we go on like this?"

Bai Su was worried.

Although before leaving, the master had asked her to take the understanding poison pill.

But what she was more worried about was the danger hidden in the poisonous fog.

For example, the giant snake.

"It's all right. Let's go."

If she would have feared the black fog before, now she has guessed a clue.

Took Bai Su to the edge of Tiankeng, found the part that Yu had dug before, and tied the rope.

Bai Su had to go down in front of her, but she sternly refused.

You know, in such a place, martial arts is not a great advantage.

You can almost see the whole picture here during the day.

Just as she and Yu found out that night, the bottom of the Tiankeng could not be seen, but there were many holes in the inner wall of the Tiankeng.

Some are tiny, while others can accommodate one person.

Instead of choosing the previous one, she chose a hole that looked like it could lead to the inside.

Just landed, Bai Su seemed too nervous.

You know, the black snake is still there.

Lin Mengya patted her hand and motioned her to relax first.

There is no smell of blood or stink here, but just like the cave we entered before, the more we go inside, the stronger the toxin will be.

Finally, she saw the poisonous ice wall as she wished.

"Master, what is this?"

Bai Su followed her, as if surprised by what was in front of her.

Lin Mengya looked back and asked, "how do you feel now?"

After experiencing it carefully, Bai Su said, "everything is as usual, master, what's the matter?"

Lin Mengya was afraid of her hard support. After checking it herself, some guesses in her heart were finally implemented.

"When I came with Yu before, the cave was in the opposite direction. However, we also found this thing in the innermost part of the cave."

She pointed to the poison ice wall.

Bai Su didn't understand what she meant. Lin Mengya sighed and explained to her, "I doubt it's surrounded by an ice wall. If these holes can lead to the end, they may only see the poisonous ice wall."

This poison has a very strange characteristic, which she found by chance.

The toxins brought out by the black fog will soon change from gaseous state to solid state, that is, small ice residue.

The poisonous water on the soles of her shoes formed ice somehow after she went out.

In other words, unless the temperature reaches a certain level, the poison itself is very easy to freeze.

Living, for example, its normal state is solid, but the temperature can turn it into gas and liquid to a certain extent.

Due to the landform here, most of the vaporized poisons will be brought back. In this way, once the black fog below no longer erupts, the melted poisons will eventually become solid, that is, ice.

This time, she wanted to observe how much the poison fog would take away and how much it would stay.

You know, Yanxia mountain is still quiet now, but after autumn and winter, when the strong wind blows, there are fewer toxins left in the mountain.

So if we can master these rules, we may be able to completely improve the poisonous insects or other poisonous species here.

However, these require complex calculations.

Fortunately, she has some medicine.

After learning some basic information, Lin Mengya hid with Bai su.

Just like before melting the poison ice, it has consumed most of the heat. In addition to the toxin, the temperature can't cause them any harm.

The air in the small hole where they are hiding is still fresh. Especially when the poisonous fog dispersed and floated, they didn't feel anything wrong.

"Master, how long will we stay here?"

Although Lin Mengya said again and again that it was still very safe here, Bai Su couldn't rest assured.

"Just wait until those people come."

She has been using systematic observation and recording data.

Xiaoyao has used the detection function to roughly estimate the storage capacity of this ice wall.

Soon, another poisonous fog eruption came.

Small medicine real-time monitoring, soon got the first-hand data of scattered overflow and decline.

According to her estimation, if nothing happens, these data will have a preliminary estimate by the last poisonous fog eruption in the evening.

She is still optimistic about the future.

When all the poisonous fog was about to fall back, Xiaoyao reminded her that she found the whereabouts of the big snake not far away.

Lin Mengya was curious.

She always wanted to know the relationship between the snake and the poisonous fog.

Quietly took Bai Su and went outside together.

She won't act rashly.

I made an appointment with Yu before. Let Yu just come here one step ahead of time.

At the entrance of the cave, she lay on the ground with Bai Su and looked at a black figure lying on the cave wall not far away.

The giant snake is very long and occupies at least half of the cave wall.

Bai Su silently clenched the long sword in her hand, but Lin Mengya was absorbed and looked at the action of the black snake.

The last time the three people died here, it was not because of the strong corrosiveness of the poison, but because once it entered the body, if it had no drug resistance, it would combine with the blood and turn the blood into corrosive poisonous blood.
