Mu Xiwan pondered for a moment, and finally made a decision.

"Well, I have an idea." Mu Xiwan said slowly to Leng Thirteen beside him.

Hearing this, Leng Thirteen quickly came to Mu Xiwan's side and looked at Mu Xiwan.

"What's the idea?" Leng Thirteen asked out loud.

Mu Xiwan groaned slightly, and then slowly spoke: "Now that the twelve killers are outside, with the ability of the two of us, there is definitely no way to solve them." ”

"That's right." Leng Thirteen nodded and replied.

So, Mu Xiwan took a deep breath and continued: "Then we can't be brainless, just thinking about ourselves to fight against them, this idea is also very unrealistic. ”

Hearing Mu Xiwan say this, Leng Shisan seemed to know what she wanted to express, and he was suddenly a little stunned.

"What do you mean......" Leng Thirteen raised his eyes to look at Mu Xiwan, and there was a touch of heat in his eyes.

According to what Mu Xiwan said, there was still hope for them to get rid of the twelve killers.

"Yes, with the help of external forces." Mu Xiwan nodded vigorously and replied.

Hearing this, Leng Shisan quickly understood, and was about to say something out loud, but Mu Xiwan continued to speak.

"What is the most external force we can use now to get rid of the Twelve Killers?" Mu Xiwan looked at Leng Thirteen and said in a deep voice.

Leng Thirteen was stunned for a moment, and then thought for a moment.

Soon, Leng Thirteen thought of something, and said in a deep voice: "Yes...... These toxic fumes! ”

"Yes, that's it!" Mu Xiwan quickly took Leng Thirteen's words.

Hearing this, Leng Thirteen thought carefully.

If you want to use these poisonous fumes against the Twelve Killers, it is indeed feasible.

"However, these poisonous fogs are definitely useless to them." Immediately afterwards, Mu Xiwan continued.

Hearing her say this, Leng Thirteen nodded: "Indeed, these poisonous fogs are still too a piece of cake for them. ”

He had heard of the Twelve Killers, and these poisonous fogs were really not enough for them to kill them.

"I know them, the exercises practiced by their twelve killers are all extremely vicious, so it is estimated that ordinary poisonous fog like this will not work for them." Because he knew something about them, Leng Thirteen said this to Mu Xiwan.

Hearing this, Mu Xiwan nodded quickly, indicating that she understood.

In fact, she had already guessed that these poisonous mist would have no effect on their twelve killers, so now Mu Xiwan was not too surprised.

"There's no intention of expecting what these poisons will do to them, we can only find some other poisons to deal with them." Mu Xiwan said in a deep voice.

Leng Thirteen nodded and responded.

There is only one method now, and the other methods are estimated to be useless, if they don't rely on external forces but fight directly, then they will definitely fail.

So they had to find a different way.

At this time, Feng Chengyi, who had been in a semi-comatose state, woke up in a daze: "Ahem......"

Hearing Feng Chengyi's voice, Mu Xiwan hurriedly stretched out his hand and hugged his body: "What's wrong with you, is there anything uncomfortable?" ”

Now she doesn't know what to do about Feng Chengyi's poison, and in this Medicine God Valley, she can't find an antidote, let alone a doctor.

Now Feng Chengyi can only drag his poison so weakly.

Mu Xiwan was actually worried for a long time.

"I ...... It's okay......" Feng Chengyi coughed twice again and spoke slowly.

Hearing Feng Chengyi's weak voice, Mu Xiwan couldn't help but worry about him even more, and hurriedly continued to hug Feng Chengyi tightly, a little overwhelmed.

Now that they are besieged in this Medicine God Valley, embattled, Feng Chengyi is highly poisoned, and she doesn't know what to do.

At this time, Feng Chengyi continued to speak weakly: "...... I heard your conversation, ahem...... Be safe, you know? ”

Hearing Feng Chengyi say this, Mu Xiwan's eyes were suddenly blurred by a layer of fog, and he could only grit his teeth hard, unable to say a word.

"If you really can't do it, don't worry about me, and run away by yourself when the time comes, they are all coming for me, and they won't care about you, you know?" Feng Chengyi gritted his teeth and continued to speak.

Hearing this, Mu Xiwan immediately gritted her teeth hard and forced her tears back.

After being silent for a moment, Mu Xiwan gritted her teeth and said in a deep voice: "You just shut up for me, I won't leave you alone, you are poisoned now, don't talk anymore, don't worry about me, I will definitely take you out of here safely, do you hear?!" ”

Looking at Mu Xiwan, who was suddenly ruthless, Feng Chengyi's dark eyes stared at her for a long time, and then laughed softly.

"Good...... Got it. Feng Chengyi smiled helplessly and replied out loud.

Mu Xiwan raised his head and looked at Leng Thirteen again, and gritted his teeth: "We must deal with the Twelve Killers, and we must not let him be in any danger." ”

Hearing this, Leng Thirteen also nodded firmly and quickly replied: "Hmm!" ”

Subsequently, Mu Xiwan thought for a moment and spoke slowly: "Although they are cultivating extremely yin and poisonous exercises, the more yin and poisonous martial arts are, the more yin qi must be consolidated by yin qi. ”

Hearing Mu Xiwan's words, Leng Shisan seemed to be a little surprised, thinking that this Mu Xiwan still knew some poison.

After only being silent for a moment, Leng Thirteen nodded: "That's the case, and they are not immune to poison, but they are protected by too domineering poisons, so ordinary poisons can't invade." ”

"So what should we do?" Mu Xiwan continued to ask.

Leng Thirteen had no way to answer this question for a while, and he couldn't help frowning, a little embarrassed.

After pondering for a moment, Leng Thirteen slowly said in a loud voice: "In this way, wait for me to think about it." ”

After speaking, Leng Thirteen fell into thinking and thought for a long time.

After a long while, Leng Thirteen suddenly looked up at Mu Xiwan and said fiercely: "I know!" ”

Mu Xiwan was taken aback by Leng Thirteen's sudden voice, and just looked at him blankly.

"Know what?" Mu Xiwan was stunned for a while before asking.

"I probably know what their martial arts need to see to consolidate." Leng Thirteen continued.

"What is it?" Mu Xiwan hurriedly asked.

"They all need to replenish yin qi, and it is a lot of yin qi, when is the yin qi the most?"

"Yes...... At night? ”

Leng Thirteen immediately nodded: "That's right, it's night, and the night of the full moon is the most suitable." ”

At this time, Mu Xiwan quickly understood the meaning of Leng Thirteen.

"You mean to attack them on a full moon night?" Mu Xiwan asked out loud.

"Yes, it's fifteen in a few days, and it happens to be the night of the full moon, and then we will release poisonous smoke on them while they are doing the twelve killers."
