The words fell, and I saw that outside, a figure slowly walked in, and actually looked at the Marshal's Mansion as if it had entered no man's land.

Mu Chen turned his head, frowned slightly, and said, "Mad Immortal!"

The person who came was none other than a mad immortal.

I saw him come to Mu Chen's side, sat down directly on the chair, and said with a smile: "Anyway, you have been in retreat for so many days, and I don't see you cultivating, let's say, is it that you kid is secretly meditating on the method of merging the Dao again?"

Mu Chen's heart moved, and he said with a smile: "That's right, I have indeed been meditating on the method of merging the Dao for the past few days!"

The mad immortal's eyes lit up and said, "Then what progress have you made?"

After the last time Mu Chen tried to merge the Dao for the first time, the mad immortal saw that if there was anyone else in this world who could successfully merge the Dao, it would be Mu Chen.

Therefore, he cares very much about Mu Chen's every move.

He didn't seem to show up in the past few days, but in fact, he was secretly observing Mu Chen, and he knew Mu Chen's actions well.

"You also saw that I had found out some clues, but the Heavenly Maiden came at the critical moment, and all the clues were disrupted!" Mu Chen shrugged, after these few days of Rongdao meditation, he had a certain degree of confidence in Rongdao, but when he thought that the result of his hard thinking and meditation for seven days was disrupted like this, he was still inevitably a little unhappy in his heart.

"What, you really figured out some clues?" Hearing this, the mad immortal's face changed, and he immediately grabbed Mu Chen's arm excitedly, and said, "Come, you can tell me, what kind of Dao are you thinking about in the past few days?"

Mu Chen paid attention to the mad immortal's every move, and he always had a feeling in his heart that this old man was by no means simple.

Although he was only a Golden Immortal cultivator, the feeling he gave Mu Chen was unfathomable, and in him, Mu Chen even had the feeling of facing the Ten Thousand Dao Heavenly Maiden.

Although Mu Chen was a little helpless about his obsession with Rongdao, this obsession made Mu Chen have to admire.

"So far, the only two powers I have ever seen that are integrated are the Kuimu Thunder Tribulation, do you think that in addition to the fusion of Kuimu and Heavenly Thunder, I will also consider other fusion paths? But I also said that at the critical moment, all my thoughts were disrupted, so don't ask me what I think, my mind is very messed up now, and I can't say clearly!" Mu Chen said truthfully.

"Hey, Wan Dao, this woman is really a harmful spirit, and she will always make trouble at critical moments. This is thanks to the fact that Poor Dao can't beat her, otherwise she would have been cleaned up a long time ago!" the mad immortal was angry for a while, obviously very dissatisfied with the Wandao Heavenly Maiden's troublemaking at the critical moment.

"By the way, fellow Daoist, you are still planning to participate in the Seven Realms Competition, right?" Suddenly, the mad immortal thought of something, and changed his words.

"Is there a problem?" Mu Chen frowned.

"Of course there is a problem, is it okay if the problem is big! I have estimated your strength, and in your body, I feel a power far beyond that of a master of the same realm. Although you are only the cultivation of the peak of the Heavenly Immortals, your strength is not weak even compared to the peak masters of the Xuan Immortals, plus your immortal sword, if there is no accident, there is basically no problem with sweeping most of the Xuan Immortal masters under the Golden Immortals. But if you want to win the title of the first place under the Golden Immortal, it is a fool's dream, because the person you will face next is the only woman whose talent is comparable to that of Wan Dao for hundreds of millions of years, and it is basically impossible for you to defeat him!" the mad immortal gloated.

"Are you so sure?" Mu Chen's eyes narrowed, and he said.

"Of course, let me tell you this, although that kid is only a half-step Golden Immortal cultivator now, but the average Golden Immortal placed in front of him is not enough for him to kill. You must know that from Xuan Immortal to Jin Xian, it is a qualitative transformation, so to speak, even a hundred Xuan Immortal cannot be the opponent of a Golden Immortal, do you think, with his strength to fight with Jin Xian, you can beat him?" the mad immortal nodded and said firmly.

"I haven't tried, who knows. Since you have said so, I am very curious, if he is against you, who is stronger and who is weak?" Mu Chen smiled indifferently.

"How can this be compared, in this entire Heavenly Palace, except for the two perverts Wan Dao and Taishang, you go out to inquire who is the old man's opponent. This kid can't say that he hasn't achieved the Golden Immortal yet, even if he really enters the Golden Immortal, the poor Dao doesn't take him seriously, okay!"

Seeing this, Mu Chen's heart moved, and sure enough, this old way looked sloppy, but it was not difficult to hear from these words, even if it was placed in the entire Heavenly Palace, it was a well-known existence.

"Hey, no, aren't we talking about your business, what are you doing on Poor Dao? Of course, if you listen to the poor way, the poor way can help you think of a way, maybe you still have a chance!" As he spoke, the mad immortal thought of something, and glared at Mu Chen dissatisfied.

"Then tell me, what can you do?" Mu Chen said with a smile.

"Rongdao, only Rongdao is your only chance now. At this moment, you are already at the peak of the Heavenly Immortal cultivation, and if you want to break through to the Xuan Immortal within a month, it is basically impossible. And even if your cultivation breaks through to the Xuan Immortal, it can't be the opponent of that Tianjiao. But if you can succeed in fusing the Dao, its power will definitely skyrocket, and even if you fight with Killing Tianjiao at that time, how about it!" the mad immortal smiled at Mu Chen with a successful smile on his face.

"Speaking of which, don't you just want me to discuss the theory of Fusion Dao with you!" Mu Chen was speechless, looking at the mad immortal and said.

"That's right, that's exactly what the old man thinks, but it's also the only way to fight against Killing Tianjiao at the moment. You just believe in the poor Dao, as long as you can really succeed in the Dao, Killing Tianjiao will definitely not be your opponent, on the contrary, you can't fight Killing Tianjiao at all!"

"You don't have to provoke me with this, even if you don't say it, I will seriously try to integrate the Tao in the future. But I'm not going to deal with Killing Tianjiao, although I don't know what is so powerful about Killing Tianjiao, but in this battle, I can definitely win the first place. Don't you want to witness my fusion path, then you just wait here, if you really want to succeed, I will be the first to let you know!" Mu Chen shook his head and smiled, directly debunking the mad immortal's radical Dao.

"Really?" The mad immortal didn't care at all that his radical technique was exposed, but his eyes lit up.

"Of course!" Mu Chen nodded, and then without hesitation, he turned around and returned to the room.

"In that case, that Daoist friend, you should enlighten first, and the poor Dao is waiting outside here!" The mad immortal looked at Mu Chen's back and hurriedly shouted.

Although there is only one month left before the Seven Realms competition, the mad immortal is very curious, Mu Chen, who can comprehend something in seven days, will have a greater harvest in this month's time.

The rest of the day was unusually calm.

Before Mu Chen's retreat, he had already arranged many things that should be arranged, and during this retreat, he began to fall into a state of no distractions.

More than half a month has passed, and he has almost been simulating the fusion method of the power of Kuimu and the power of heavenly thunder.

On this day, he opened his eyes suddenly, and two gleams flashed in his eyes.

Eliminating all dangers and impossibilities, he finally found the key point of integration.

"It's done!"

Mu Chen secretly screamed in his heart, and between the waves of his hand, a small trace of Kuimu power appeared in his left hand, and a subtle power of heavenly thunder appeared in his right hand.

Although the power of Thunder and Kuimu is small on this day, the power is extremely great, because it is still in the attempt, Mu Chen does not dare to call too much strength, otherwise there will be another explosion, and even he will be miserable.

As the two powers emerged, Mu Chen's eyes became more determined than ever, and he stared at his hands deadly.

On his palm, the two forces swirled wildly, and as the two hands slowly approached, the two forces began to slowly touch, and then fused.

"That's right, that's it!"

Mu Chen rotated the two forces, and when he saw each other, his eyes suddenly lit up.

This fusion of power is definitely hard work, and if you make a slight mistake, you may lose all your efforts.

Seeing that the two forces began to cross and fuse, Mu Chen did not dare to be careless, and the two primordial spirits who controlled the two forces were connected, and mastered the balance of power to the extreme, so as to grasp the balance of power.

Gradually, the two forces fused more and more closely, and they were about to merge completely, and at this moment, a strange feeling suddenly came to my heart.

Mu Chen's heart moved, he was inexplicably nervous, and then his arm trembled.

"Boom!"

A violent explosion suddenly sounded, and the violent force spread out in all directions, instantly bombarding the entire room to pieces.

Mu Chen trembled, and a powerful force swept across his body, and the power of crazy thunder directly scorched himself black.

This is not the first time Mu Chen has done this thing by releasing the heavenly thunder to split himself, after the tribulation before, he did it once when he tried to melt the Dao, but he didn't expect it to come again now, he didn't care about it, but he was a little excited in his heart.

"What's the matter, failed again?" At this moment, a figure hurriedly rushed into the room and hurriedly shouted.

Mu Chen looked up and saw that the person who came was a mad immortal, and couldn't help but smile bitterly.

"Childe, how are you, are you okay?" Biluo Fairy also rushed in, looked Mu Chen up and down, and said with some concern.

"Don't worry, Biluo, I'm fine, you go and prepare a room for me first, and I'll continue to retreat later!" Mu Chen waved his hand and instructed Biluo.

"Okay!"

Biluo glanced at Mu Chen up and down, and saw that Mu Chen really didn't have any problems except for a little embarrassment, so he couldn't help but secretly breathe a sigh of relief.

"Fellow Daoist, I didn't expect you to start trying to merge the Dao so quickly, although you still failed, but what strange feelings do you have?"

After Biluo left, the mad immortal immediately asked impatiently.

"No, there is no failure, I succeeded!" Mu Chen shook his head and said firmly.

"What, it worked?"

The mad immortal was stunned for a moment, a little stunned.

It's all blown up like this, and it's still called success?

"That's right, mad immortal, let me ask you, you have been trying to melt the Dao for hundreds of years, have you ever thought about what conditions are required for the Fusion Dao?" Mu Chen nodded and asked rhetorically.

"Of course I have thought about this poor way, but unfortunately all the time, fundamentally, all the problems that can be found out, the poor road has been found, and there is still no way, do you still know what conditions?" said the mad immortal with a frown.

"Of course, let me ask you again, how many avenues have you cultivated at the same time?" Mu Chen asked rhetorically.

"Of course this is one, manpower is limited, it is not easy to control a great avenue in a lifetime, it is not easy to achieve an immortal venerable, the poor dao has not achieved an immortal venerable yet, where can I have so much energy to cultivate other avenues? However, although the poor Dao has not cultivated the superfluous Dao, but over the years, the Poor Dao can be seen, perhaps because the poor Dao cultivation is single, and there is no multi-force cooperation, which leads to the inability to melt the Dao, therefore, in addition to the Dao of Gengjin, the Poor Dao has cultivated the power of the Five Elements of Water in addition to the Dao of Gengjin for hundreds of years, and wants to integrate the power of Gengjin and the power of the Shui Xing, but it has been unsuccessful, do you think that the conditions for this cultivation are also the conditions for the Dao of Fusion?"

The mad immortal said without doubt.

"No wonder you can't merge the Dao, the conditions for this Dao fusion are indeed the same as the conditions for cultivation. This is like two people, one is a supreme immortal venerable, and the other is an ordinary mortal, do you think these two people can reach a cooperation? They are not the same world at all, they don't even have the opportunity to go to each other, where can they still merge with each other? The way of Gengjin in your body is your natal avenue, and the way of water is just your casual practice, the strength of the two forces is not in contrast, and naturally it cannot be fused!" Mu Chen nodded and said seriously.
