Dan Dao, in ancient times, was often called breathing, guiding, qi, convincing, alchemy, monasticism, zazen, etc., divided into internal and external two, Neidan is guided by the idea of the unity of heaven and man, with the human body as the furnace, the essence and spirit as the medicine, and the practice of condensing the Dan in the body. Huo Ranwen ???.? ｒ?ａ?ｎ?? E?n?'net Outer Dan, relative to Inner Dan, also known as alchemy, elixir, golden pill, smelting, yellow and white arts, etc., refers to the use of furnaces to smelt gold stones, prepared into bait, with it as a carrier, with a trick, the yin and yang. To be an immortal golden pill.

But after the last human war, many rare medicinal materials have been completely extinct, so the latter is unrealizable, as for Zhang Taiyan's cultivation strength, it belongs to the former, from the inside out, as for the fighting spirit, it is like the outer door, focusing on lethality, from the outside to the inside, the starting point of the two is different, one is used to live a hundred years and break through the limit of human life, and the other is to focus on fighting and killing a hegemony.

"Cultivating both inside and outside is the right way, but it's a pity that it's late, you can imitate the Dou Qi for cultivation, plus you have been transformed into the human body, so it should be very convenient in the comprehension of the Dou Qi, as long as you use your strength to simulate."

"What about the Great Elder?"

"Me?" Fei Lian smiled bitterly, looked at the sky outside the window and said: "It's probably very difficult, from the outside in, it is a very difficult thing, it is even more difficult to reach the source realm, now I want to practice to the extreme, to prove the Tao with strength, maybe there is a glimmer of possibility, if you can cultivate strength and fighting spirit at the same time, the two practice together, the possibility will be greatly improved, but now I am too old, I want to train my strength from scratch, it is difficult, probably only one way to go to the dark." ”

"If you cultivate to the origin realm, you can live for at least a thousand years, but because of the long-term battle, there are basically no people who have cultivated to the origin realm who can live to a thousand years old, that is, my mother, the great person who established the valley, but when the valley was besieged by fifty barbarian elders who cultivated to the golden fighting spirit, the self-detonating origin kept this half-human territory, and by the way, it severely damaged the foundation of the barbarians, providing the half-human clan with at least fifty years, so that the half-humans got the opportunity to recuperate and grow."

"It's not easy."

"Yes, at that time, I was just a silver fighter, it was really a difficult time." Fei Lian's face is full of vicissitudes.

Zhang Taiyan looked at Fei Lian, and his side face looked very similar to Mao Xiyu.

When she was discovered, the energy in her body had already begun to circulate, and the same was true for Fei Lian on the side, silently, amicably fighting, fighting in simple momentum, Zhang Taiyan was pressed, but he could still deal with it, but the strength to speak was basically not much.

"Yes, Yu Xiu'er's words, you are probably already sweating now, and you can still look at ease, it is worthy of my training, your strength can now be said to be the limit of the human body."

For about a quarter of an hour, for Zhang Taiyan, it seemed that he had spent several lonely retreat periods, and the slightest tiredness in his heart made Zhang Taiyan, who had just broken through, feel a little surprised, that he could be suppressed to that point, and it was simply oppression in momentum.

The momentum of relaxation, the two of them who simply sit.

Calm.

Fei Lian opened the window to let the moonlight in further.

"Boy, do you like Mao Xiyu?"

"Great Elder.." Zhang Taiyan was a little stunned, a moment ago he was still discussing the realm after the origin, but now he jumped directly to the issue of feelings.

"Let me ask you, do you like Mao Xiyu?"

"I... Like, but simply like it as a companion. ”

"It's really troublesome, why can't you refresh yourself?" Fei Lian's hand condensed a moonlight-like fighting spirit, played with it, and said: "I remember that she is your friend who is with you day and night, life and death, in this case, if it is a good choice as a lifelong companion, if you are indecisive, be careful that such a good woman leaves you." ”

Zhang Taiyan was a little silent, he didn't know how to answer, and deep down he thought of a strong figure, Zhong Leyuan.

"Don't mother-in-law, Mao Xiyu's heart is also in you, I think you can't miss her in your heart, isn't it just right for the two to be together?"

"But..."

"If you're worried about heirs, I say, aren't you a scientist? Aren't you able to play with artificial fertility devices, and it won't be long before you get one yourself? There are many ways to have children, and it doesn't have to be a woman, think about the scientific and technological capabilities of the last era, people in that era did not need to give birth by themselves, and completely relied on external forces, eliminating the pain of childbirth. ”

Zhang Taiyan covered his face, and now he likes to cover his face more and more.

And so the conversation of the evening ended.

...

A week later, Zhang Taiyan was completely ready, and put away all the props that could be put into the space storage box, this time the materials were completely exhausted, especially the materials of the mecha, basically it was goodbye to maintenance, and if you wanted to repair something, you basically had to disassemble the chuck to see if the materials were enough.

The bronze broken sword was now lying firmly in the sword box, and some dry food had been collected. Mao Xiyu on the side brought enough hot spring eggs, it seems that she likes to eat this very much, and some candied fruit made of peaches.

Ready, the two said goodbye to their acquaintances in the valley, Zhang Taiyan said goodbye to the children and Lily, some of the children cried and said to Zhang Taiyan, telling him to remember to come back and marry them after ten years, of course, Elder Pan Ani also came over with a concerned face, asking if he wanted Lily to accompany him, and then he was pulled away in his granddaughter's arm turning over the silver, in fact, it was better to hug than to pull, Lily's strength is really amazing, and he will probably have a good impression of her, it is this characteristic that overlaps with Zhong Leyuan.

After the two of them passed through the long black tunnel, Mao Xiyu walked somewhere to the side and pushed a rock into it, and the huge rock that closed the valley slowly rose.

"Let's go!" Mao Xiyu smiled slightly and said: "The teleportation array is directly connected to Rhode Island, but if you set it up again, it will take a little time, if you come to help, it can be done within about an hour." ”

"Let's go, I don't really like the cold."

The two of them disappeared into the snowfield.

In the distance, ten miles away, Fei Lianyao looked into the distance and muttered, "They should go." ”

"Yes, they are gone, so the battle between me and you should begin."

"Well, that's good."

Fei Lian looked indifferently at the tiger-headed man in front of him, his body exuded a fierce light, it was a power that could destroy everything, not so much a fighting spirit, but something similar to nuclear energy.

"Oops, haven't felt this way in a long time, am I going to die?" Fei Lian said worriedly. (To be continued.) )
