Zong Fan, who was leading the team in front, saw Lu Lin swaying the green demon fire crystals that everyone regarded as treasures in the ancient city. When he saw Lu Chen, as a father, had no intention of being mature and stern. He stared at the fire crystals in his son's hand and his eyes began to shine. His face couldn't help but twitch hard. He glared at the father and son with anger and said, "You guys, you should save money. It's not good to use too much that thing."

Lu Lin glanced at Zongfan in surprise and said in confusion: "What do you mean by senior?"

Lu Chen and Zuo Qinghan were also confused by Juhe.

Zong Fan laughed twice, stopped, snatched a fire crystal and looked around for a while, throwing it into Lu Chen's arms like throwing garbage, and said, "This thing is indeed mellow, but you haven't noticed that there is any problem with the refining of the girl Qinghan?"

"What's the problem?" Lu Chen hurriedly looked at Zuo Qinghan again.

Zuo Qinghan looked at herself in confusion and said thoughtfully: "Senior reminds me that I just felt something was wrong, as if something was wrong?"

Zong Fan reminded: "Your state of mind."

Zuo Qinghan suddenly realized her bright eyes and said, "Oh, my mood seems to have not improved?"

Lu Chen and Lu Lin frowned one after another.

"You haven't noticed it?" Zong Fan rolled his eyes and said, "I really don't know how you practiced. I haven't discovered such a clear problem. Please look at the Qing Demon Fire Crystal. Is the vital energy inside different from the vital energy of heaven and earth?"

"It's very pure, huh..." Lu Chen picked up a fire crystal and put it in his palm, and used the immortal technique to induce the fire crystal vital energy into the purple palace. As soon as he opened his mouth, he found a problem: "This... seems a bit too pure." Even though he knew there was a problem, Lu Chen still couldn't tell what the key point was. He immediately tried twice again. Lu Chen said in shock: "I understand, the vital energy in the fire crystal does not have a spiritual surname."

"What does it mean?" Everyone looked at Lu Chen together.

Zong Fan tilted his mouth and said, "It's not bad yet, you can tell it's pretty good."

"Is this praising me or scolding me?" Lu Chen curled his lips.

"Praise you." Zong Fan glared at the old eyes: "The Qingmo Fire Crystal is a pure Yuan crystal derived from the Master Fire Pattern. In theory, he has the spiritual surname of Qingmo Fire, but you find that there is only Yuanqi here, so where is there any spiritual surname?"

Now, everyone understood what it meant, picked up the Green Demon Fire Crystal and tried it one after another, and the result was greatly disheartening.

In addition to "yuan", the most important thing is "yuan". The so-called "yuan" refers to the five elements of vital energy, and the two yin and yang energy are derived from the world.

After the monks absorb and breathe, they then refine the meridians, they transform the "element" and "yuan" into the true essence of the natal world, that is, magic power. The "element" here allows the monks to border the heavenly secrets after absorption and refinement, which is the so-called "enlightenment". Thus, while improving their mental state and cultivating, they can broaden the space of the purple palace and store more magic power. That is, "yuan".

The "yuan" of the Green Demon Fire Crystal is completely true, but the "essence" energy has been lost. It can be said that during the cultivation process, the "yuan" that is constantly filled with the purple palace has existed. If the "essence" is not there, it is impossible to improve the state of mind.

To make it clear, refining the Green Demon Fire Crystal cannot improve the mental state of mind, but there is a way to improve the concentration of mana. After a long time, the mental state is insufficient, and the magic power stored by the Zifu exceeds the range that the mental state can bear, and he will end up being in a devilish way.

Generally speaking, this kind of obsession will not cause people to lose their original surname in a crazy way, but as their cultivation improves, the true essence of the natal body will not accumulate. First, it will not be able to exert its due strength. Second, whenever they encounter bottlenecks, it will become extremely difficult to break through. The most direct thing is that it will lead to failure in advance and great loss of cultivation.

Everyone is a master who has been practicing for a long time, so they naturally understand the principle of balance. In fact, the practice of heaven must follow the word "natural". If you only care about one end during the practice process, one will rise and fall, and something will happen sooner or later.

Zuo Qinghan realized for a while and said in surprise: "Oh, I said why has my mood improved so slowly recently? It turns out that too much fire essence has been refined."

Zong Fan narrowed his eyes and said, "You have used the Green Demon Fire Crystal once. Fortunately, your state of mind has reached the state of a superior god. The fire of the fire crystal can allow you to break through to the superior god. If not, I am afraid you are still a middle god now. And just now, I see that you have a bad attitude, your state of mind is not up to the state of mind, your qi and meridians are abundant, and you have a sign of strong and weak energy, so I concluded that this fire crystal is very problematic. Girl, according to your current magic power, you are more than enough to reach the lower god, and you have not been able to advance. Because of your lack of mind, in my opinion, you should save money on using the fire crystal and improve your mental state of mind first."

"Forget it, I'll just leave one." After hearing this, everyone nodded, especially Ju He simply left only one of the Green Demon Fire Crystals, and returned all the rest to Lu Lin.

Zong Fan pointed at Lu Lin without hesitation and said, "And you, you have used this kind of thing a lot over the years. Don't use it in the future. Be careful that you will never reach the realm of the God King."

Zongfan is a peerless old Gu left behind from ancient times. Although his cultivation level is not as good as the Eight Kings of the Divine Realm, he was a real master in the past, and his mind was extremely strong. To put it bluntly, if it weren't for the fact that he and Wu Li would have recovered from their cultivation level before the battle between gods and demons. His broad knowledge was that even the few people in front of him could not compare with him.

Lu Lin was holding a bag of Green Demon Fire Crystals in a discouragement and opened it to everyone for a look. There were more than thirty pieces: "It's hard for me to collect so many and I can't bear to sell them. I should have taken action on the black market at the beginning." As he said that, Lu Lin was about to throw away the Green Demon Fire Crystals.

"No." Lu Chen was shocked, and grabbed the Qiankun bag in his hand, saying, "Boy, aren't you wasting this? The senior said that he would use less before his mood was not up to the point. If his mood was far beyond his own cultivation, this thing would be a treasure."

"Yes." Ju He and Lu Lin, who had already asked Zong Fan to say, had their heads drooped, their eyes began to shine.

"Give me a few more dollars and find an opportunity to learn the ancient method and practice the state of mind first." Ju He said and began to grab it.

Lu Lin rubbed his hands and laughed and approached Lu Chen step by step: "Dad is right, so give it to me."

Zuo Qinghan burst into laughter, then patted Lu Chen's shoulder with a tense face, and pretended to be angry: "Give the things to the child quickly. Is there anyone who is a father robbed the child's things?"

"My mother is right." Lu Lin said seriously.

"Okay, okay, I surrender." Lu Chen raised his hands and threw the Qiankun bag back. He had no intention of robbing Lu Lin's things. He was all a family, so whoever held it was the same?

"Give me two more pieces." Ju He looked at Lu Chen with a gaze.

Lu Lin was generous and took out three pieces and threw them over.

Such a warm scene made everyone laugh for a while, and Zong Fan twisted his goatee and pondered silently.

Lu Chen looked at the scenery that had not changed much, frowned slightly. When he first came in, he saw the colorful post road at least for a while, but after watching it for a long time, he always felt dizzy. He said impatiently: "Senior, how long have we been in?"

"It will take about two hours." Ju He thought about it and replied.

Zong Fan nodded, and his expression turned solemn: "This Qinghuo is very capable, and the post road is tortuous, which shows that his third level of heaven is extremely open and it is really difficult to find for a while."

"Oh? Senior, why are you going back?" Lu Chen looked at it intently for a while, and suddenly realized that Zong Fan always took everyone forward and retreated for a while, confused.

Zong Fan laughed and said, "Boy, what do you know? I have also used the Xuantian Post Road method in the past. Most monks use the Nine Palace Reverse Method to create mazes, which means that if it is empty, it is real, and if it is real, it is empty. This will save you much trouble."

Lu Chen suddenly realized and carefully observed, and then he found that the purpose of Zong Fan's blind progress was to observe the pattern of the maze, and then based on his experience, he guessed that there were several possible surnames, and adopted the method of elimination to slowly look for clues. Now Zong Fan has almost determined several routes to find them.

Seeing Zongfan's confident look, Lu Chen was rarely interrupted and seized the time to adjust his breath.

Seeing that Lu Chen stopped talking, Ju He and Lu Lin stopped talking.

After flying for a while, Zong Fan's figure suddenly paused and said with a smile: "Finished."

"Finished." Everyone was energetic. At the same time, they opened their eyes and saw that the colorful passage disappeared. There was only a straight green passage that appeared in front of them.

The passage was narrow, only enough for two people to move side by side. The ground, the ceiling and the walls on both sides were filled with surging green magic fire. The strong smell of gunpowder was very pungent. What shocked everyone was that the temperature here was extremely high, several times higher than that of the Qinghuo Pond. A hundred meters away from the front was a wooden fence door tightly closed. There was a door here, and the remains of the Great Lord were almost about to emerge.

"Just there, rush in."

After finally finding the eyes of the Tiansheng Magic Formation, even Zong Fan, who had always been steady, couldn't help but show his joy. With a wave of his hand, everyone stood up happily.

At this moment, a shocking wave of fire swept across the crowd, and the narrow passage echoed with dull shouts of extreme anger.

"How dare you move my magic circle and die?"

This sound of Xuankong Duwai was thrilling. It came from afar. Lu Chen and others were all in a daze. At this moment, an old figure burst into pieces with a huge anger. It was the lord of Taiwu Ancient City and the old monster Qinghuo.

Zong Fan stood in front, his cultivation was the highest among the people, and he was the first to react from shock. When he was in danger, the old god of Zong rushed back and came behind everyone, turned his Dharma body and sacrificed his profound immortal power.
