Time flies, five years in the snap of a finger.

The experience in the world of "The Legend of Double Dragons of the Tang Dynasty" is like a big dream, and only the Waidan crystal ball in Ji Ning's hand proves that all this is true.

Through the second primordial god among them, he was able to clearly distinguish the different natures of heaven and earth primordial qi within a radius of tens of miles.

There are countless kinds of Heaven and Earth Yuan Qi in Heaven and Earth, and the White Emperor Gengjin Immortal Sword Code can refine most of the Heaven and Earth Yuan Qi and turn it into the purest Gengjin Sword Qi.

It's just that the efficiency of refining Heaven and Earth Yuan Qi is different, there are several kinds of Heaven and Earth Yuan Qi that are more difficult to refine, and there are several kinds of Yuan Qi that are particularly easy to refine, and there are several kinds of Yuan Qi that are like stones, hard and ......

Ji Ning experienced this subtle feeling, and took advantage of the situation to change the way Wai Dan swallowed the vitality of heaven and earth.

He immediately felt that the combination between Heaven and Earth Yuan Qi and Wai Dan had become even closer.

The huge Heaven and Earth Yuan Qi is like a lively elf, seduced by the Gengjin Sword Qi, making all kinds of responses.

Even without refining the Outer Dan Crystal Ball, he could sense Ji Ning's thoughts, and many changes were born under the manipulation of Gengjin Sword Qi.

Within the scope of his primordial sense, every wisp of Gengjin sword qi was like a commander, dominating the vitality of heaven and earth with similar attributes.

This is the third level of the Qi cultivation period, the mysterious realm.

To go further, it is necessary to condense the evil qi of the earth's veins, refine the Nine Heavens Gang Qi, and practice with the help of the magical power bred between heaven and earth, which is called the foundation building period. It is also divided into threefold: condensation, refining, and returning.

Ji Ning put away the Waidan crystal ball, and the bronze treasure mirror in the sea of consciousness was communicated with his mind, and now there were only 17 parts of the power of time left (this should be correct).

This time the real body crossing also verified one of his ideas, when the "traces of time" on the wheel of life are completely erased, as long as it still remains in a crystal flawless state, the bronze treasure mirror can not continue to draw the power of time from it.

You can't win 'em all!

Ji Ning went to take a shower first, changed his clothes, and lay on the bed quietly looking at the starry sky outside the window.

His mind was empty, he didn't think about anything, and soon he fell asleep.

The next morning, the sun rose in the east and the sun shone on the earth.

Ji Ning's mind emerged from the darkness in the deepest part of the sea of knowledge, and the moon set and the sun rose in the sea of clouds in the dantian, changing with the time of day.

In a thought, the inner and outer heaven and earth are connected, like a breeze, like flowing water, and naturally blend into the nature of heaven and earth.

The days of Beishan University are busy and fulfilling, and Ji Ning devotes all his time to studying every day in addition to practicing.

After stepping into the Tongxuan realm, the original limit was broken, and Ji Ning's small goal at this stage was to have 10,000 layers of the bitter sea.

The commentary in the opening chapter of the Wheel of the Sea Scroll of the Tao Sutra reads: "The sea of suffering is ten thousand layers, and the essence of life is as vast as the ocean, and it is endless.

Cultivating to this realm, condensing the earth's veins and yin, refining the nine heavens of Gangqi, returning to one, Yuan Dan nine turns, and casting Jindan into the avenue. Hurry! ”

Ji Ning cultivated into a thousand-layer sea of clouds, and spent more than one million spirit yuan before and after, and if he wanted to cultivate into a nine-thousand-layer sea of clouds, he had to get at least ten million spirit yuan.

If he had taken the time to go through the layers of penance, it would have taken him about two or three hundred years.

The foundation of the thousand-layer sea of clouds will be very different from the foundation of the sea of clouds of ten thousand layers, and the future achievements will be very different.

Therefore, Ji Ning is going to refine the "Fire Tribulation" and "Water Poison" on the Earth Star, the former can be called "Sun Spirit Essence", and the latter is naturally "Moon Spirit Hua". Then use the "Sun and Moon Essence" to earn a lot of spirit yuan.

The Ji family has the secret method of "Yin and Yang casting sword fetus", and the Nanyang Ye family inherits the "Taiyin Righteous Law", the solitary yin does not grow, and the only yang does not give birth, whether it is the "flower of the moon spirit" or the "essence of the sun spirit", it will be sought after by everyone.

In addition to the Ji family and the Ye family, there are thousands of monks in Daming, and the market is extremely broad.

The spirit yuan in Ji Ning's hand was all smashed into the deep pit of "Sun and Moon Essence".

Danfang is similar to the formula of traditional Chinese medicine, and it also pays attention to the "monarch and minister", and the absence and replacement of a medicinal material will lead to the adjustment of the entire Danfang, which is extremely complicated.

On the twenty-sixth day of the lunar month, in an alchemy room of Tianji College of Beishan University, Ji Ning turned off the furnace fire, slapped it out with one palm, and went to the lid of the Dan furnace.

"Whew......"

A roar of air sounded, and dozens of white gases erupted from the holes, soaring into the sky.

When the exhaust gas dissipated, he stepped forward to take a look, only to see pills the size of a dragon's eye rolling in the Dan furnace.

Ji Ning stretched out his hand, and the pill at the bottom of the furnace flew up and served it with the gourd that had been prepared long ago.

And when I counted them, there were thirty-six.

"Please Mr. Xu to taste."

Ji Ning handed the gourd to Xu Jing, a middle-aged beautiful woman standing next to him.

"Very good, skillful and accurate. The quality of this furnace 'Purple Cloud Qi Gathering Pill' must not be bad. ”

After Xu Jing finished speaking, he poured out a pill from the gourd, put it in front of his nose and sniffed it lightly, and then said, "Zhongpin." ”

"Thank you, Mr. Xu." Ji Ning said with a smile.

Xu Jing took out a spirit talisman and pasted it at the mouth of the gourd, saying, "What are your plans for this holiday?" ”

"Is there something wrong with Mr. Xu?" Ji Ning asked.

Xu Jing signed Ji Ning's transcript and said, "How about my lab need to recruit a few assistants, and give priority to students from our school?" There is no interest. ”

Although she is not the top alchemist of Tianji Academy, she is the backbone of the first-class alchemist, which is a rare opportunity.

Ji Ning thought for a while, and politely declined: "Teacher Xu, I already have arrangements at home for the holidays. I'm so sorry. ”

Now that he has made preliminary results in his research on the "Sun and Moon Essence", he is planning to go home to lira to invest a lot, and other things must be put aside first.

Xu Jing was a little disappointed, handed a signed transcript to Ji Ning, and said, "I've been in school for the past few days, if you regret it, you can come to me at any time." ”

"Hmm." Ji Ning nodded. Looking at Xu Jing's voice walking away quickly, he thought in his heart, "Monk, naturally a cultivator is the first. Alchemy is just a skill to earn spirit yuan, otherwise it would be quite good to follow Teacher Xu.

I heard that she also has a daughter, who is beautiful and has excellent alchemy, and is known as the number one beauty in Tianji Academy......"

The next morning, Ji Ning stepped on the super railway to return to his hometown, and returned to Tongbai County all the way safely, and did not encounter any messy things.

He first went to the patriarch Ji Hongzhe's house to sit down, and then went to the cemetery of Ji Yifan and his wife to pay respects, and finally lived in the courtyard of Qingteng Jingshe.

"Tuk-tuk."

Ji Ning knocked on the door of the "Kun" self-numbered courtyard.

"Squeak." The door opened from the inside, and a middle-aged man who looked like he was flying violently, with a leopard's head and eyes, and a tiger's beard, walked out. This person is the Ji family foundation monk who is responsible for guarding the Qingteng Jing Society, Ji Yihai.

"Ning'er, you came back from Luoyang, do you have something to do with me?" Ji Yihai said, stepped forward, and patted Ji Ning's shoulder with a big fan-like hand.

Ji Ning's body seemed to be thin, but he didn't move like a mountain, and said, "Uncle Yihai, do you have a 'Flame Pill' here?" Borrow a few and let me study them. ”
