It seems that Geng Wu really doesn't know......

"Tianhe, Weak Water, and Lethe River are actually the same river. The water source of the Tianhe River was destroyed...... It won't be long before the weak water and Lethe River will dry up one after another. Ye Yao said faintly on the side.

"What?!"

Geng Wu's hand trembled and pointed from Gengzi to Ye Yao, "Are you sure? It's impossible! Tianhe is in the Nine Heavens, the weak water is in the mortal world, and the Lethe River is ......under the Nine Springs."

With a gesture of his hands, he finally sat down.

(Draft, unrevised.) Piracy is shameful. ）

That's the result of a little knowledge of astronomy and geography. Such a clear fact that no one has ever mentioned it.

Gengzi sighed, "We still have time. Countermeasures must be thought of before Lethe dries up. ”

"How did you deal with it back then?" Ye Yao asked.

Gengzi was stunned, "Back then, we had nothing to do. The eighteenth benefactor asked the Celestial Clan for help, but fortunately, thanks to the help of the Protoss, the 'Soul Extermination Array' sealed the 30 million fierce spirits of the riot in the underworld. ”

Today's Protoss is also greatly damaged. I'm afraid I won't be able to muster the same amount of power as I did back then.

"Since the 'Brahma Heart Earth Lotus' can absorb everything, why not use it to absorb the spiritual consciousness of the undead?" Ye Yao held her chin and glanced at the fire pool.

"Stop the idea of a relic. The little benefactor is still in it, even if the Netherworld collapses, you can't risk it!" Geng Wu muttered dissatisfiedly.

Gengzi immediately chimed in, "Back then, Father God brought the benefactor to the bank of the Lethe River, ignited him to create the Netherworld, and established the rules of the six realms of reincarnation. Even if the Netherworld is razed to the ground, the main benefactor is still there, and we can always get the evil spirits that should be caught. Without him, the cycle of reincarnation between the human world and the underworld would disappear, and our existence would be meaningless. ”

I never expected that a casual proposal would cause such a heavy topic.

"I'll just talk about it......" Ye Yao hurriedly cleared up.

Suddenly, I found that the Netherworld was facing a huge contradiction.

On the one hand, evil spirits are wreaking havoc in the world, and more and more mortals will die. Their spirits must enter the underworld as soon as possible in order not to be infected by the resentment of the evil spirits and then alienated. On the other hand, if the Lethe River dries up, there is no way for the undead to be washed of their spiritual sense, and they cannot enter the underworld.

At that time, the Netherworld will have to stop extraditing the undead and stand idly by and watch the world become another layer of purgatory.

The human race is the most vulnerable part of the Six Realms, but it is also the primate of all things in the four seas of Kyushu. They were most likely to be exterminated, but they were never expected.

At that time, the eighteenth benefactor thought of a solution. We've tried it again and again, and we're almost on the verge of success......" Gengzi muttered.

Ye Yao raised her eyebrows, "What way? It almost succeeded, but it didn't work out—"

"Lethe water washes away the spiritual consciousness of the undead, so that they only have memories and no temperament. Then when you enter the underworld, you will be like a walking corpse, you will not have grudges after being tortured, you will not cause trouble, and most importantly...... Won't turn into an evil spirit. ”

Gengzi cheered up and continued, "At that time, the ghosts searched all over the Six Realms, and they didn't find a good way to quickly strip off the spiritual consciousness of the undead. So the eighteenth benefactor came up with an idea - not to strip the spirits of the dead, but to erase their memories. In this way, even if you are a murderer with a tyrannical temperament in your lifetime, because you have forgotten those painful experiences in the mortal world, even if you have a bigger temper, you can achieve the same effect. ”

"That's fine—"

Ye Yao's eyes lit up, "There are a lot of spells in the Immortal Dao to erase memories, but I don't know if it has any effect on the spirit." ”

When Gengzi heard this, he shook his head and waved his hand: "No——, no! At that time, the masters sent by the Heavenly Clan and the Divine Clan had all tried, and the immortal art was used on the undead, and it was easy for them to disappear. If the undead are all tossed, there will be no more mortal rebirths, and it is also a crisis of extinction. ”

Ye Yao nodded seriously, "I see, no wonder you didn't succeed." ”

"Alas, we almost made it!"

Gengzi raised his hand and took out a worn-out bamboo slip and handed it to her, "At that time, Tang Chao Shenzun helped find an ancient relic, called Worry Relief Tea. It is mild in nature and suitable for fragile organisms. As long as the decoction is brewed according to the recipe and let the undead drink it, they will lose all memories of the person to whom the seven emotions are related. ”

"Anxiety Relief Tea!"

Ye Yao's eyes widened, and she quickly took the bamboo slip, and asked as she unfolded it, "Since there is a recipe, why didn't you make a tea soup?"

The same...... The same...... , almost exactly the same!

"Because there are several defacements, some of the herbs and dosage of the decoction are unclear. I tried many times, but I couldn't make a suitable decoction. The ancient relics are exquisite, and the slightest difference has no effect. ”

Gengzi's voice came, and Ye Yao almost didn't listen to a word.

Except for the defaced part on the bamboo slip, the many medicinal materials on this recipe are only blindly different from the one she has been studying.

If what the Divine Venerable gave was the real ancient recipe of "Anxiety Relief Tea", wouldn't the decoction she gave Meng Xu'an drink before be completely ineffective......

Carefully holding the bamboo slip, she walked between Gengwu and Gengzi, pointed to the defaced position and said: "Here, 'Meng Jiangcao' Qiqian, here, 'Nine Heart Dry Lotus', and here, the 'Red Sand Demon Root'." You take it and give it a try. ”

Geng Wu was stunned.

This girl...... What the hell is the way to come from?! Even if he was Yunmeng Shuijun, he couldn't know everything!

The eighteenth generation of Hades and many masters of the Heavenly Clan and the Protoss couldn't figure out the ancient recipe, and she was so casual and pointing. Combined with previous experience, this look is mostly the meaning of nine out of ten.

He was still in a daze, Gengzi on the side had already offered a pen and paper, wrote down what Ye Yao said one by one, took back the bamboo slips, bowed his hand, and turned to leave.

Time is of the essence, and as long as there is a glimmer of hope, we cannot sit idly by!

He had a premonition in his heart: Ye Yao did not come to the Netherworld for no reason, her arrival was completely providential, and it was a glimmer of life left by the "Mandate of Heaven" to the Six Realms......

......

"Why are you still here?"

Sitting cross-legged by the fire pool, Ye Yao was in a daze, and lazily asked Geng Wu who was staring at her.

"The old man is here, waiting for his dispatch. Geng Wu replied.

Knowing that he was staring at him here, Ye Yao didn't bother to expose it, and continued: "Have you thought about a question? If the Netherworld falls, how will Mo Lian be taken out?"

It turned out that I was thinking about such a stupid question in a daze for a long time.

Geng Wu couldn't help laughing, "Hi-"

He patted his thigh and said with a smile: "The 'Brahma Heart Earth Lotus' is nourished by the 'Netherworld Ghost Fire', and wherever the Heavenly Fire goes, it will go." If something really goes wrong, as long as you turn the Heavenly Fire into a Red Fire Sword and take it away, it will naturally follow. ”

"Oh-"

Ye Yao dragged out a long note meaningfully.
