This powerful Yuan power nourishes Lan Xin through the dual cultivation of yin and yang, making her cultivation more stable and her strength greatly increased.

And during the dual cultivation period, Yitian can easily use his own power to temper Lan Xin's body and improve her cultivation level.

In this regard, Lan Xin has a great advantage. She uses the power of Yitian to temper the soul and body, which at least doubles the overall strength, and increases the capacity of the inner meridians of the body by more than half, reaching the peak level of the intermediate Martial Emperor.

Of course, the combination of Lan Xin and dual cultivation also gained a lot for Yitian. The red yin energy in Lan Xin's body is extremely nourishing to Yitian. Moreover, the magic tricks that Lan Xin practices are from the Demon Soul Forest, which is very different from the magic tricks that ordinary people practice.

In the first dual cultivation of Yin and Yang, the amount of Yuan power in the celestial body of the mind has not increased, but its quality has improved.

Lingbi Guiji's strength also skyrocketed, refining Meng Ao's external incarnation and the lifelong cultivation of the thirteen martial emperors of the Shanggong family.

Previously, Gui Ji recovered about two levels of strength, and after that night, Gui Ji's strength returned to about three levels of the Quanwei period.

Yitian discovered that the speed of Guiji's recovery of strength was changing step by step, with easy first and difficult later, and the span was extremely large.

For example, it is not difficult to recover from one percent to two percent.

However, it is half harder to recover from 2% to 3% than before.

This step change, which is becoming more and more difficult the later, shows that Gui Ji's special physique and his terrifying strength are both extraordinary spiritual weapons, and even immortal weapons cannot compare with them.

An old saying goes, "Solar Yang does not grow, lonely Yin does not grow, and Yin and Yang complement each other and change impermanently.

The changes in Lan Xin by dual cultivation are mainly reflected in strength and cultivation.

The changes in the dual cultivation of the mind and heaven are reflected in the quality of the Yuanli and the application of Yuanli.

These are two completely different concepts, which are related to the two people's own conditions.

The momentum becomes Tai Chi, embracing Yin and Yang.

Yitian and Lan Xin were dedicated and practiced seriously in the second half of the night. The yin and yang energy in each other's body circulated back and forth for twelve cycles, which greatly tempered Lan Xin's body and soul.

Yitian's cultivation level has also increased significantly. After the fire dragon's essence in the body has melted the red yin energy in Lan Xin's body, the oscillation frequency has reached more than 21,800 times in an instant, approaching the limit of the primary Martial Emperor.

After being promoted to Martial Emperor, Yitian has a new change in the use of power. The capacity of the inner energy of the body has also increased greatly. It is obviously more difficult to be promoted to the intermediate Martial Emperor.

Why is this happening? Yitian feels confused. He is full of doubts about his body and feels that the difference between him and ordinary people in improving his realm is too big.

It was early morning, Yitian finished his yin and yang cultivation, lay quietly on the bed, enjoying Lan Xin's service.

There were so many things happening to Yitian this night, looking for people, saving people, fighting fiercely, and challenging him. A series of things made him feel excited but a little tired.

Of course, the most important thing is that Yi Tian was promoted to Emperor Wu. After the restless Yuanli in his body was nourished by the yin energy and became peaceful and quiet after practicing both Yin and Yang with Lan Xin, his entire body became deeper and mysterious, making him unable to see through his background.

The quality of the magic formula will determine a person's cultivation level, and it will also affect a person's inner temperament and external personality.

After Yitian experienced the dual cultivation of Yin and Yang, he clearly felt that the structure of the primordial power in the body had changed, resulting in some changes in the body, the primordial spirit was also affected to a certain extent, and his personality was also different.

Of course, these differences are not obvious, and it is difficult to detect without careful attention.

Lan Xin's experience in this aspect is not as strong as Yitian. She just clearly felt the improvement of her cultivation and strength, her soul became more concise, and her thought oscillation frequency increased significantly. She did not feel much change in her personality.

Early in the morning, several amazing news came from Feiyun City, which made the originally quiet Feiyun City suddenly boil.

The first news is that the sword-casting tripod of the Gongsun family was stolen, and it has a lot to do with the boundless city, one of the seven miracles in the legend.

As soon as this news came out, it immediately caused a sensation in the city, and countless experts were closely following it.

After all, the Borderless City is one of the seven miracles. It is said that there are infinite treasures hidden, which is extremely tempting for those who practice the truth.

The second news is related to the three evil sects in Nanyang. Last night, the masters of the three evil sects appeared at the same time in the Yin Zi Tomb, killing many martial emperor-level masters in Feiyun City, which caused a sensation in the whole city for a while.

It is said that the three evil sects in Nanyang have not appeared in Feiyun City for ten years. This time, the three sects appeared at the same time, which is obviously not that simple.

According to insiders, the three evil sects came this time, one was to compete for the sword-making tripod and to find the extremely deserted city.

Second, there are other purposes, and there are many different opinions on why.

Some people say that the Evil Immortal Sect is for the thousand-year-old mummy in Yin Zi Tomb, while the Spirit-Driving Sect is for finding something.

As for whether it is right or not, no one can say sure.

The third news has something to do with Yitian. First, someone in the Yin Zi Tomb was promoted to Emperor Wu, which made it earth-shaking. Unfortunately, no one knew who the promoted person was.

Then, Yitian showed his power in the Shangguan family. In front of Emperor Xuan, Shangguan Jinhong, he killed thirteen martial emperors in one breath, causing the four words Nangong Feiyu to sensation in Feiyun City overnight.

The fourth news is related to the Thousand Years of Corpse King. Although its breath only appeared for a while last night, it was a martial emperor-level powerhouse after all, and any movement would be enough to shock the land of Nanyang.

In addition to these four sensational news, countless things happen in Feiyun City every day. This morning, many foreign experts flocked to Feiyun City.

At the morning of the morning, a sign of heavenly disaster appeared above Ruifeng Tower, which attracted many people's attention.

This time the heavenly tribulation is coming in a fierce manner. Although it is not as shocking as when Yitian was promoted last night, it should not be underestimated.

Dark clouds gathered in the sky, and purple-blue lightning fell from the sky and entered the Ruifeng Tower.

The Martial Emperor's Heavenly Tribulation is more mysterious. It can attack from the air and directly act on the person who has passed the tribulation. It is difficult for external objects to stop it.

This time the person promoted was Yitian's follower Gu Wu. He only took three days from the Martial Soul to the Martial Emperor. This speed is incomparable to even a peerless genius.

The heavenly tribulation that Gu Wu faced was much more terrifying than ordinary people because he had an immortal leg fused with his body, which was destined to be extraordinary.

Yitian and Lan Xin stood outside the Gu5 Gate, watching purple and blue lightning falling directly through the void without any intention of interfering.

Yitian knew in his heart that Gu Wu had the legs of an immortal on his body, and this heavenly tribulation was beneficial or harmless to him. It could greatly temper his body and accelerate the fusion of his and the legs of an immortal.

Facing the heavenly tribulation, Gu Wu seemed very calm, and new energy was constantly growing in his body, allowing him to deal with it easily.

The duration of the heavenly tribulation of Gu Wu was at least twice that of ordinary people. During this period, Gu Wu took the opportunity to reshape his body, incorporated the immortal's legs into his right leg, and returned to his normal body shape.

In this way, Gu Wu's right leg has extremely terrifying explosive power, his body is as hard as steel, and he cannot enter the knife, gun, and water and fire.

Someone who was promoted to Wu Emperor of Ruifeng Tower naturally attracted the attention of the masters in Ruifeng Tower. Ruixue also hurried to the 18th floor. Yitian ordered her to prepare a new suit for Gu Wu.

After a long time, the heavenly tribulation passed, Gu Wu changed into new clothes, his whole body was radiant, although he was not handsome, but also very energetic.

Lan Xin took out a secret book and handed it to Gu Wu, and said with a smile: "This is what the master asked me to give you. It records the cultivation method of the Xuan Armor Golden Body, as well as the Hunyuan Thunder Palm, two unique skills that kill the heart leg. The master told me that after you are promoted to the Martial Emperor, you will send you to the cave to practice. With your current situation, your strength will be greatly increased by most days, your cultivation will be greatly improved, and you will have the ability to defend and attack."

Gu Wu was excited and said, "I will definitely step up my cultivation and strive to serve Su Ruifenglou and the young master as soon as possible."

Yitian nodded with a smile and ordered Gu Wu to follow Lan Xin to the crypt.

After a moment, Lan Xin came back and left Ruifeng Tower with Yitian and entered Feiyun City.

At this time, Yitian was already a celebrity in Feiyun City. He killed the thirteen martial emperors of the Shangguan family in one breath last night, which laid a high status and status for him in Feiyun City.

"Xin'er, Feiyun City is so big, is there anything special?"

Standing proudly in the air, Yitian looked at the huge Feiyun City, and for a moment he didn't know where to go.

Lan Xin smiled and said, "There are so many special places in Feiyun City, such as the Four Evils, Three Saints, Eight Mysterious Sects, where does the Young Master want to go?"

Yitian asked: "Apart from the Four Evils, Three Saints, Eight Mysteries, there is nothing else that is relatively ordinary but has some highlights?"

Lan Xin pondered: "Xin'er has been away from Feiyun City for ten years, and her childhood memories are mostly blurred. In Xin'er's memory, there is a stele without words in the west of the city, which seems very interesting."

Yitian said curiously: "Interesting?"

Lan Xin recalled: "The wordless monument is very strange. People who are destined to see the handwriting on it, while people who are not destined to see nothing."

Yitian suddenly became interested when he heard this and asked, "Where is the wordless monument? Take me to see it."

Lan Xin pondered, "I have only seen the wordless monument once, but I went with my master. I remember it was in a temple and most people couldn't get in at all."

Yitian didn't care about this and pulled Lan Xin and flew west to the city.

"You can take me to find the wordless monument first, and I will deal with other things."

Jian Yitian insisted on going, but Lan Xin didn't say much. Based on her childhood memories, she took Yitian straight to a desolate old city west of the city.

In Feiyun City, this is a slum, with low houses and curved streets that cannot be compared with luxurious areas at all.

Yitian paid attention to the movements in the nearby area. There were a large number of people below the Martial Master level living here, and no one with advanced cultivation was found.
