The matter was settled, Lonely Chi didn't stay any longer, he just spoke to Ling'er and then returned to his spiritual place.

Lonely Chi opened his eyes and saw Xu Zhiruo sitting opposite him, concentrating on practicing the mental method of cultivating the truth taught by him. Xu Zhiruo was extremely talented. Although he didn't practice the mental method taught by Dugu Chi for a long time, he made a lot of progress. , it is estimated that in two months, I will be able to touch the first-level bottle of Qi training.

Seeing Xu Zhiruo practicing hard, Dugu Chi was wondering whether she should refine some elixirs to increase her training speed, and he also needed the assistance of elixirs to improve his cultivation.

"Brother, you should take the time to take a look at the thing in the soul-locked heart pearl that your master left behind. Ling'er is also very curious, what could it be?" Ling'er's voice sounded in Duguchi's mind.

"Oh." To be honest, Dugu Chi was also very curious about what the master had left behind, but there were too many things to deal with during this period, so this matter was dragged off again and again. Now that everything is done, it's time to You can take a look at those things.

After days of hard work, Dugu Chi still needed a good rest to recuperate his energy first. So Dugu Chi said something to Xu Zhiruo, walked to his own stone room, and slept on the couch. Originally, there was only one independent room in the cave. The two of them were going to stay here for a long time, so Duguchi opened another stone room on the other wall as his own bedroom, and the original stone room naturally became Xu Zhiruo's bedroom.

He was very tired. Dugu Chi had a good sleep. When he woke up, it was already the afternoon of the second day. After a brief wash, Dugu Chi walked out of the cave. For a moment, he felt that the sun was shining brightly, the air was particularly fresh, and he felt refreshed. A jolt.

Seeing Dugu Chi coming out, Xu Zhiruo quickly heated up the cooked food and brought it over. While watching Dugu Chi eat, she concealed her complaint and said, "Brother, it's true. You don't need to work so hard in training."

Hearing Xu Zhiruo's concealment of complaints, Dugu Chi just laughed and said: "Things have just come together during this period, but it's okay. They are basically solved. It won't be like this in the future. Don't worry, Ruo'er." After speaking, he raised his hand and pinched Xu Zhiruo's cute nose. This action naturally caused Xu Zhiruo to feel angry.

After dinner, Dugu Chi gave Xu Zhiruo some pointers on her practice and asked her about her familiarity with the staff. Speaking of her staff, Xu Zhiruo was extremely satisfied. She had basically mastered the function of the staff. Especially the technique of driving the beast soul to attack and the ghost whistle attack are extremely sharp to use.

With the help of this staff, Xu Zhiruo now has no difficulty in fighting two cultivators who are one level higher than himself at the same time. Three of the beast souls in the staff have turned into evil spirits. That was during Xu Zhiruo's trial. , grew up by devouring the souls of the killed monsters, and let him drive the beast souls in the staff to devour each other, she couldn't do it yet.

"You should pay attention to communicating with the staff more often, so that the connection between it and you will become closer and closer." Dugu Chi imparted his experience to Xu Zhiruo.

"Ah, communicate with the staff. It's not just a dead thing. How to communicate?" Xu Zhiruo found it a little difficult to understand Duguchi's request.

"Haha, when you shed your blood and recognized the master, there was a connection between you and the staff. I believe you also know what it feels like. In fact, strictly speaking, this staff is not a dead thing. At least you can't treat it as a dead thing. If you often inject your own vitality into it and nourish it, the connection between it and your soul will become stronger and stronger, and its effectiveness will become greater and greater. "Dugu Chi said with a smile. For people in this world, all this is still a bit difficult to understand. Fortunately, Xu Zhiruo believed in Dugu Chi's words and believed that his brother would not lie to him.

Seeing that the time was almost up, Dugu Chi confessed to Xu Zhiruo, and his soul entered the sea of ​​consciousness again. Seeing that Ling'er was not in the sea of ​​consciousness, Dugu Chi entered the world of Qiankun in a flash. Since Ling'er was no longer in the sea of ​​consciousness, Then it must be in this world of heaven and earth.

Today's world of Qiankun has become very different from before. Green grass is everywhere, and the distant mountains are covered by lush forests. At this time, Ling'er was sitting cross-legged under the tree of life, frowning in deep thought. For a long time, she couldn't help but sigh. Tone: "Well, it seems that I thought of that matter a little simpler." Ling'er shook her head helplessly.

"Is there anything difficult? Why are you sighing?" Duguchi's voice came from behind. Duguchi and Ling'er can control themselves to appear anywhere in the world of Qiankun. "I guessed it right, you are here, how are you? "Tell me, what's the embarrassing thing?" Duguchi asked while smiling and sitting down next to Ling'er.

"Oh, hehe, brother is here." Ling'er smiled and put her little hand into Duguchi's palm. "Did you hear me?"

"I heard you sighing when I first came here. Why, is there something embarrassing that makes my Ling'er sigh too?" Dugu Chi smiled and held Ling'er's hand, looking at his sister dotingly and asked.

"It's not about those saints. I'm afraid we thought too simply before." Ling'er said with a frown.

"Oh, could it be that the idea of ​​combining the beast fire spirit condensation method with the soul infusion method is not feasible?" Dugu Chi guessed.

"That's not true. I've deduced this method and it should be feasible. It's just that it's a little difficult to give life to these saints." Ling'er said.

"What exactly is going on? Please tell me carefully." Duguchi also cheered up.

"Brother also knows that the life seal that Ling'er received before was incomplete, so at that time Ling'er used the incomplete seal to speculate that as long as there is a tree of life in the world of heaven and earth, it can give the power of life to all the saints. However, when I was cultivating the Tree of Life, I obtained some rules of life and completed the incomplete seal of life, and then I realized that what I thought at the time was too simple.

The growth of this tree of life is also divided into levels. Each level will produce an additional horizontal branch, and the functions of each level are also different.

The first level can only give birth to lower life forms such as flowers, plants and trees.

The second level can give birth to life forms without spiritual consciousness such as earthworms.

The third level is for low-level spiritual beings such as fish, shrimps, clams, and clams, and the fourth level is for higher-level spiritual beings such as cats, tigers, and wolves.

Only at the fifth level can highly intelligent life forms like humans be born.

The sixth level can give birth to various spiritual beings such as dragons and phoenixes. At this level, it can also provide enough vitality for monks above the human Nascent Soul.

The Tree of Life cannot grow to this level, and in this world of heaven and earth, it is impossible for monks to reach the realm of Nascent Soul.

The supply of vitality at the seventh level can meet the vitality needs of the first-level flesh saint. This flesh saint is equivalent to the current emperor-level cultivator in the outer world.

The eighth level is for the vitality needs of the world's gods. It is the level when the saints return to their peak state.

When the Tree of Life reaches the ninth level, this world will transform to the highest level of the Great Thousand Worlds." At this point, Ling'er stopped and looked at Dugu Chi, waiting for him to digest this information.

Duguchi thought deeply for a while and asked: "Then the Tree of Life is only at the first level, so naturally it cannot supply the vitality required by those saints. In other words, under the current situation, those saints cannot have life."

"If they have life now, then it is possible for the current tree of life to replenish the life that has passed due to the passage of time, but it is impossible for them to have life under this situation." Ling'er said. "Without life, even if you give them a soul, the soul will gradually dissipate."

"So, is there no way to increase the level of the Tree of Life?" Duguchi asked.

"There is a way to do this, but it's extremely difficult." As if thinking of the difficulty, his brows furrowed even more.

"What can I do? Why don't you tell me what to do?" Lonely said, out of curiosity.

"It's about gaining the power of the two elements." Ling'er said. Looking at Dugu Chi's puzzlement, he smiled and explained: "My brother knows about the five elements. They are gold, wood, water, fire, and earth. And The so-called power of dual elements refers to the power of yin and yang, one of the five elements, such as the dual soil of yin and yang."

"Then what are the two true extremes?" Duguchi asked.

"Haha, these two true yin and yang golds are respectively the Yang Soul True Gold and the Nine Nether Yin Gold. With the power of the two golds, you can create a tree, remove the evil spirit in the Tree of Life, and make the Tree of Life stronger. Upgrade one level. The two trees of true yin and yang, namely hibiscus branch and flower of the other side, can be used as a support tree to strengthen the true essence of the tree of life, and can also raise it to one level. As for the two true waters, its yin water It is the water of the Yellow Spring, and the Yang water is the dew of the bright sun. It can be obtained by the method of growing trees."

"Ah, the water of the underworld, since the Six Paths Saints cannot possess life or give souls, then it is probably impossible to generate the underworld in the six paths." Hearing Ling'er talk about the underworld water, Lonely Chi suddenly remembered something. question.

"Of course, every road is blocked." Ling'er said with a helpless smile.

"Oh, what are the other true and extreme dual-acting objects?" It was useless to think about it, and Duguchi had to go back to the original question.

"What about the other ones? The twin fires. They are the Nine Yang Tiangang Fire and the Nine Netherworld Flames. They can be used to turn wood into trees and open up the veins in the tree of life, just like you open up the meridians in your body. The twin earths are Nine Heavens Breathing Soil and Nine Nether Soul Condensing Mud can be obtained by cultivating wood and cultivating its roots. This Nine Nether Soul Condensing Mud is an attached thing next to the Soul Stone, and it will exist next to the Soul Stone. If you can Obtaining all these five elements and ten ultimate things will definitely lead to the creation of the Tree of Life reaching the sixth level. However, it is simply too difficult to obtain these things. In my brother’s previous life, after so many years in the world of Xun Daqian, I was just I've only seen two or three kinds." Ling'er sighed.

"Yes, it's really not an ordinary difficulty. By the way, when you said you gave life to the saints, how did you give it to them?" Duguchi thought of another question.

"Haha, I'm afraid my brother doesn't know that vitality is calculated in years. Take a person as an example. Normally, a person's vitality flows evenly. If a person is born with a hundred years of vitality, Then this person will have a hundred years of life if there is no disaster. If a body with intact physical characteristics and intact soul has no life, then you only need to inject five hundred times the life force that a person consumes per year into its body. This will bring it back to life.

Take those holy saints as an example. They are influenced by my level. Now, as long as they are given souls and a thousand times of the life force consumed by a human per year is poured into their bodies, they can gain life." Ling'er explained with a smile.

"Ah, that's it." Listening to Ling'er's explanation, a spiritual light suddenly flashed in Duguchi's heart. "Inject life force. By the way, can those saints take pills?" Duguchi asked.

"Of course you can take elixirs. Although they have no soul life, their body functions are still functioning normally in this world, so they can naturally take elixirs. My brother said that they should take elixirs that increase their vitality. Huh, this may not be easy. The best elixir you know can only increase a person's vitality for ten years at most. How can you refine it with more than a hundred elixirs? ." Ling'er understood Gu Lonechi's thoughts and smiled to herself.
