"Simple?" He Wangwu and Su Su asked in unison, and stared at Mu Heng with monster-like eyes, trying to figure out if Mu Heng really felt simple.

Seeing such a strange reaction between the two of them, Mu Heng muttered: Could it be that he guessed wrong?

"Isn't it?" Mu Heng also asked rhetorically.

"I don't know where you got your confidence, but not to mention the true fire of the sun, even the Taiyin true water, which is relatively easy to obtain, is not too easy to obtain. Panda: Where do you get your confidence? Su Su followed.

"Uh...."Mu Heng didn't know how to answer, and wondered in his heart that the Sun True Fire was not as easy to get his hands on as the Taiyin True Water.

"I have Taiyin real water here." He forgot to see Su Su asking, and interjected inappropriately.

"You...."He Wangwu's sudden interjection made Su Su unable to get off the stage, and just now he solemnly explained to Mu Heng the difficulty of obtaining the Taiyin True Water, and he was immediately grasped by He Wangwu.

Mu Heng also stared at He Forget worry in some surprise when he heard this, thinking to himself how can you have Taiyin True Water, and what you said just now seems to be too bad for Su Su, so wait a while and then take it out and sprinkle it!

The atmosphere suddenly became awkward, He Wangxian glanced at Su Su with some embarrassment, and then carefully took out a jade bottle from his storage ring.

Su Su stared at the jade bottle, not knowing whether to be happy or depressed.

Rejoice, after all, half of the second ban has been solved.

Depressed, I was invisibly squeezed by He Wang's worries and lost face.

Seeing that the atmosphere was so weird, Mu Heng hurriedly eased and said, "Fairy, where did you get the Taiyin True Water?" ”

"It's also a coincidence." He Wangwu stuck out his tongue and praised Mu Heng's coordination in his heart.

"What chance?" Mu Heng continued to ask along with the question.

"In my human race, there is a sect that I don't know where to get a lot of Taiyin true water, and I spent a lot of money to change some of it before this trip." He Wangwu shook the jade bottle in his hand and said very distressedly.

When Mu Heng saw her say this, he guessed that it must be Yuqing Xingzhai who used the method he invented to refine the Taiyin True Water and then sell it to other sects.

Continue to associate with the two key elements of refining Taiyin True Water. The making and operation of the generator should have been learned by Koyin while watching.

And the solution and ignition of the water are estimated to be Ye Qingyin's responsibility, because if the others are replaced, they will definitely be greeted by the thunder.

Su Su listened to He Wang's explanation and Mu Heng's centering, and lost his temper, and his bewitching fox eyes stared at the jade bottle, not knowing what he was thinking.

Then I heard her say: "Even if there is Taiyin True Water, but the Sun True Fire is not easy to get. ”

"Is the sun really hot? What is it? Mu Heng was puzzled, judging from the name, it should be the same level, and the difficulty of obtaining it should be close.

"Hey!" He forgot to worry and sighed deeply.

"How?" Mu Heng was even more puzzled when he heard He Wang's complaint.

"Taiyin true water is the original true water that only existed when the heavens and the earth first opened, although it is rare, but it is still produced in some blessed lands, although it is difficult to get, it is not impossible." Su Su first explained the Taiyin True Water.

"I know this, what does this sun really fire have to do with it?" Mu Heng asked.

"And this sun is really hot, close in front of you, but far away in the sky." Su Su looked up at the sky and said disappointedly.

"Oh? What does that mean? Su Su's words made Mu Heng more and more curious about the true fire of the sun, what was it that was obviously close in front of him, but it was far away in the sky.

"Panda, you see, the sun in the sky is the true fire of the sun, and the sunlight shining on us is also the true fire of the sun, but the energy of the real fire is too little and too little." Su Su pointed to the empty white sun and said.

"Sunlight?" Mu Heng followed Su Su's fingers and squinted at the sun at noon.

"That's right."

"Isn't it possible to condense the sun's rays to get the true fire of the sun?" Mu Heng guessed the characteristics of the sun's true fire, it seems to be solar energy, and if you gather more, you can make the sun's true fire.

"It's not as easy as you say." Su Su felt that Mu Heng's suggestion was very ignorant, but he didn't say anything sarcastic, who didn't come from a young age.

"How?" Mu Heng asked with his eyes written.

"This sun true fire can be condensed, but only during the day. Once nightfall, all the true fire qi of the sun will be neutralized by the yin energy, and it will be gone, and it will have to be started again the next day. Therefore, if you want to condense the true fire of the sun, there is only one daytime. Su Su looked at the sky and Mu Heng, and carefully guided him.

For some reason, Su Su liked to discuss the knowledge of these practices with Mu Heng, and he didn't feel that his grade was up to his own, so he explained it with extra care.

"Then it's okay to condense during the day, since you can condense it, then you just need to solve the problem of speed." Mu Heng also followed Su Su's train of thought and thought about it.

"Hey, Panda you're thinking too easily." He listened to the exchange between the two of them and participated from time to time.

"What do you say?" Mu Heng wondered.

"Based on the cultivation of my Sancai Mirror, if you want to condense a pinch of Taiyin True Fire flames, it will take thirty years." Su Su stretched out three fingers and put them in front of Mu Heng's eyes, and kept shaking, wanting to provoke Mu Heng's sensitive nerves.

"Thirty years?" Mu Heng stared intently at Su Su's three short white fingers, and couldn't help but raise his voice.

"So, what is enough for a day?" Su Su pouted the fox and complained.

"So Panda, you know what Su Su meant when he said 'close at hand, but far away in the sky'!" He Wuwu also had some understanding of the true fire of the sun, but he did not rush to answer, but followed Su Su to constantly echo it.

Mu Heng touched his head and thought about Su Su's words, and then he had a flash of inspiration and thought of a way, since the speed of monomer condensation is not good, then increase the production line and increase the production capacity exponentially.

Thinking about the speed of condensing the monomer corresponding to the thirty years that Su Su said, a touch of excitement and excitement appeared on his face, and he said: "According to the thirty years that Su Su said, if you let 11,000 of you condense the true fire of the sun together, then you can condense a pinch of the true fire of the sun in one day. ”

After speaking, Mu Heng's eyes were fixed on Su Su's fox eyes, waiting for her answer. I saw a confident smile on the corner of her mouth, as if she had expected Mu Heng to ask such a question, and she had already prepared the answer and waited for him.

Seeing her smile like this, Mu Heng secretly said that it was not good. Then I heard her say again: "Your idea has been put forward by your predecessors a long time ago, the question is how can there be so many three-talent mirrors in this world, and even if there is, it is from a different camp." More than 10,000 Sancai mirrors together to help condense the idea of the true fire of the sun is unrealistic. ”

"Hey, Panda, how did you calculate so fast? This conclusion is still the result of many years of research by our ancestors, how can it be estimated in less than a breath from you? After Su Su finished speaking, he realized that Mu Heng subconsciously reported the data, and he was very surprised.

"What's so rare about this, it's just a simple calculation. That's not the point. Mu Heng didn't think it was difficult, and he didn't care about Su Su's concerns.

Su Su looked at Mu Heng's disapproving appearance, and a turbulent wave surged in her heart, and her familiar temperament made her connect Panda with her former old friend.

"Then can you replace the Sancai Mirror with the Liangyi Realm?" Mu Heng ignored Su Su's surprise, but kept thinking downward, the cultivation of the Liangyi Realm was higher, and he must be able to top many of them.

Su Su then shook his head, and said helplessly: "Your idea is not new. The Liangyi Realm can replace a hundred Sancai mirrors at most, and the ten fingers of the Liangyi Realm in this world can't be used up, and it's better than nothing. ”

"Okay!" Mu Heng was also a little discouraged when he heard this, thought for a while and then asked, "Is there no other place where you can get the true fire of the sun except for the sun's rays that can gather the true fire of the sun?" ”

"No, at least that's the only way I know of the true fire of the sun." He forgot to worry that Mu Heng would have such a question, and he was ready to answer it a long time ago.

When Mu Heng heard this answer, he also understood that the true fire of the sun was unlikely to be there, and raised his head to look at the scorching sun in the sky.

"Looks like we're going to stop there!" Su Su saw Mu Heng so depressed, and the unrealistic thoughts that originally arose in her heart were also extinguished by her, this second prohibition was like a moat to her, and how could Mu Heng of the Nine Palace Realm solve it.

Su Su's exclamation was like a fuse, burning the atmosphere of the scene solemnly. He Wangwu also looked ugly, without the slightest loss of his previous fighting spirit, peeking at Mu Heng out of the corner of his eyes, there was always a little expectation in his heart, looking forward to Mu Heng being able to create a miracle again.

Mu Heng looked at the sky that was illuminated by the sun, and while thinking about whether there was any clever way to help condense the true fire of the sun, he was thinking of a way to extract the clue of "nature's blessing" from Su Su's mouth.

Su Su looked at the top of the mountain with a worried face, and then looked at the prohibition that blocked the way like a roadblock, and a deep sense of powerlessness came to his heart. looked at He Wang, who was also listless, and Mu Heng, who was buried in thought, and beckoned: "Let's go down the mountain!" ”

He Wuwu didn't want to hear this, but he couldn't do anything about the prohibition, so he raised his red fairy sword and shot out two red lights towards the gate.

When the red sword light touched the door, it was like a mud cow entering the sea, and it dissipated without making the slightest sound.

"It's useless!" Su Su saw that she was so persistent, so she persuaded her.

He forgot to worry about it helplessly, and finally resigned himself to his fate and turned to leave.

"Panda, let's go!" Su Su took the lead down the mountain and reminded Mu Heng when he passed by.

He forgot to worry about Mu Heng's blank eyes, and wiped out the only little hope left in his heart, this prohibition cannot be broken by manpower.

Mu Heng, who was still immersed in his mind, unconsciously followed the footsteps of He Wangwu and walked towards the bottom of the mountain.

"Ouch!" Without noticing a big step, Mu Heng's feet were light, and his center of gravity was unstable and he rushed straight ahead.

He Wangxian in front of him had never left Mu Heng out of the corner of his eyes, so he accurately caught Mu Heng's fallen body, straightened him and instructed: "Panda, be careful!" What are you thinking, so distracted? ”

Mu Heng, who came back to his senses, stared at Su Su, who was leading the way in front, and said in a low voice: "Su Su...."
