Zhu Zhenzhen also took a sword and a mirror, while Long Yuzhu took a jade shuttle and a sword, but they all took low-grade treasures.

In addition, there are nearly thirty jade slips in a large pile of treasures, and these jade slips are engraved with the exercises and martial arts of the Earth Demon Mountain Villa and the Shangguan family, and many of them were stolen by killing people and stealing goods.

Kuai Yu threw aside the jade slip of the Earth Demon Villa's exercises, which were either poisonous or demonic, and it was not suitable for Kuai Yu anyway.

The Shangguan family's exercises were carefully studied by Kuai Yu in his hand, and it was still not bad, especially the Lingxi Sword Finger that the ugly man had just used, but unfortunately the power was a little smaller, Kuai Yu sat down directly in the cave and studied it carefully, although it took nearly more than an hour of deduction.

Kuai Yu changed the Lingxi Sword Finger to the Ice Moon Sword Finger, the power is close to the Tianpin mid-level martial arts, and it has a stronger penetration than the Lingxi Sword Finger, and the Ice Moon Sword Finger is divided into two styles, the first style is the sword finger ice, and the second finger is called the Ice Moon Sword Finger, as for what the mystery is, Kuai Yu has not yet deduced it, and it still needs to be used for a while.

So many martial arts have also been picked by the three women, and they have ** Heart Sutra in the exercises, and there is no need to change them, but the martial arts are indeed their weaknesses, even if Kuai Yu taught a few things, they are still too lacking, and these martial arts are just enough to solve their urgent needs.

In the first layer of the Underground Demon Palace, the safest place is in the cave where everyone is at this time.

When Kuai Yu was modifying the Lingxi Sword Finger, the three girls couldn't wait to take out the selected martial arts, and silently recited and cultivated, not seeking to fully master it, but to familiarize themselves with it as soon as possible.

After all, if you master these martial arts and add a little combat experience, the strength of the three women will increase exponentially, and they will be able to ensure their safety to the greatest extent in the underground demon palace, and they don't have to be vases anymore, and the three girls are naturally enthusiastic.

Kuai Yu, who woke up, saw that the three girls were all practicing their own martial arts, and Kuai Yu, who had nothing to do, could only walk to the entrance of the cave and protect the Dharma for everyone.

After all, in just half an hour, three groups of people broke into the cave in a row, and Kuai Yu had to cheer up to prevent anyone from breaking into the cave again.

In order to avoid trouble as much as possible, Kuai Yu directly asked Da Bai and Xiao Bai to join forces to set up a phantom array at the entrance of the cave. The entrance to the cave was covered as if it had never been a cave.

After standing quietly at the entrance of the cave for a while, he saw more than a dozen groups of people passing over, and they were completely unaware of the existence of the cave. Kuai Yu subconsciously breathed a sigh of relief.

Idle and bored, Kuai Yu simply took out those refining materials and put them in his hands to play slowly, watching Luo Yun open his eyes, Kuai Yu asked her for the cloud dragon ribbon, the cloud dragon ribbon started, look at the silk like a cloud, the streamer hidden in the dragon, take out the thousand-year-old cold iron, supplemented by light blue flowers and water attribute strengthening stones, and began to upgrade the cloud dragon ribbon.

After Luo Yun glanced at Kuai Yu suspiciously, he closed his eyes and continued to cultivate, looking very relieved.

The thousand-year-old cold iron is said to be iron, but in fact, it is the condensation of the ice for thousands of years, and after being refined, it flows as clear as water, and the thousand-year-old cold iron and the cloud dragon ribbon are skillfully fused together, which can increase the defense of the cloud dragon ribbon, and supplemented by light blue flowers and water attribute strengthening stones, can give full play to the effectiveness of the thousand-year-old cold iron.

The fusion process was very dangerous, but Kuai Yu was not afraid at all, but looked calm, controlling with one hand, and drinking dragon wine with the other.

A few hours later, the three girls opened their eyes one after another, and just happened to see the cloud dragon ribbon glowing with blue light, exuding an aura that was even more powerful than just now, obviously the upgrade was successful, and it entered the final critical moment.

Luo Yun's eyes flickered, obviously she didn't expect that Kuai Yu was actually proficient in refining, even if her nature was weak, she couldn't help but scold in her heart.

"This evil is going against the sky. ”

It's done, Kuai Yu put the natal true fire into his body, and the cloud dragon ribbon gently pushed it back to Luo Yun's body.

"I see that you like this ribbon very much, and you are only a high-grade treasure, I feel that you are not worthy of your identity, and the Yunlong ribbon is barely upgraded to a medium-grade treasure. Kuai Yu looked at Luo Yun with a smile and said.

Zhu Zhenzhen and Long Yuzhu next to them looked at Kuai Yu with envy, compared to the domineering Bingji, they liked the gentle and considerate Kuai Yu more, but they were now Bingji's people.

Seeing that Kuai Yu was thinking about Luo Yun for everything, the two girls secretly made up their minds to pay attention, and when they saw Bingji later, they must make him bleed profusely.

Luo Yun nodded, lifted the veil, and nodded at Kuai Yu's face, and then all his thoughts were on the cloud dragon ribbon.

Kuai Yu had long been accustomed to Luo Yun's personality and didn't care too much, but when Kuai Yu didn't pay attention, Luo Yun's gaze at him showed tenderness, which was completely different from his usual indifference.

"We've been here for a day, and I'm afraid that if it's too late, the Yintang Cave Treasury will miss us. Kuai Yu saw that the three girls were studying the newly arrived treasure with great interest, and had to be reminded.

Luo Yun quickly nodded and agreed to set off, but Kuai Yu was worried that their strength was not good, and if they encountered a strong enemy, the three girls would be in danger.

"In this way, you can temporarily enter the Qiankun Secret Realm to cultivate martial arts, and when you have cultivated your martial arts to Xiaocheng, you use your divine sense to communicate with me, and I will let you out. Anyway, there is a time effect in the Qiankun Secret Realm, even if the speed of your cultivation of martial arts is not fast, you can also take advantage of the time difference in the Qiankun Secret Realm and cultivate well. It is estimated that it will take at most half a month to be able to cultivate the obtained martial arts to the realm of Xiaocheng, and if the speed is fast, it may be possible to get it in seven or eight days. ”

saw the three girls looking absent-minded. Kuai Yu knew that everyone's attention was on the cultivation of various martial arts at this time. Before all kinds of martial arts have not been cultivated to the realm of Xiaocheng, it is estimated that they will not have the heart to enter the underground demon palace. Kuai Yu couldn't help but smile bitterly.

After mentioning the special effects in the secret realm of Qiankun, Kuai Yu told the third girl his suggestion.

Hearing Kuai Yu's words, the three girls' eyes couldn't help but light up, because of the existence of the Qiankun Secret Realm, Kuai Yu's suggestion was completely feasible.

The time difference between the inside and outside of the Qiankun Secret Realm, they also know, but this time difference does not affect the increase in life span and cultivation at all, but it is very suitable for practicing various martial arts and life skills, no wonder Xiaobai can become the king of medicine, under the Kuai Yu Refining Codex and almost infinite elixir and a lot of time to practice, even a pig can become an alchemist.

"Kuai Yu, this is not good, we are all hiding in the Qiankun Secret Realm to cultivate, and you are suffering alone outside. We can't bear it. Long Yuzhu agreed with Kuai Yu's suggestion in her heart, but her face was full of embarrassment.

Although they have not been very effective in combat, they have always acted as a nanny for Kuai Yu's daily life, and they are worried that once they leave, Kuai Yu will not be able to take care of themselves.

Although the two daughters were also very moved by Kuai Yu's suggestion, they also didn't want Kuai Yu to face the danger outside alone, so they spoke out against it.

"You can rest assured, with my strength, there are very few people in the first layer of this underground demon palace who can put my life in danger, besides, even if my life is really in danger, I can release the shadow leopard out. ”

"The first layer of the Underground Demon Palace is much safer than the second layer. You just have to cultivate in it with peace of mind, and wait until your various martial arts cultivation is successful. Only then can we better deal with the difficulties that follow, you don't want us to be powerless when we encounter the people of the Shangguan family or the Earth Demon Villa, let alone seek revenge on Li Jianhua in the future. ”

After clearly seeing the change in the expression on the third girl's face, and listening to the third girl's rebuttal, Kuai Yu thought for a moment, decided to stick to his opinion, and ordered in an unquestionable tone.

Seeing that Kuai Yu had made up her mind, and the three girls had already studied the information of the Underground Demon Palace in detail before entering the Underground Demon Palace, they also knew that what Kuai Yu said was completely true, so everyone was silent for a while, and finally entered the Qiankun Secret Realm.

Almost at the moment when Kuai Yu sent the three girls into the Qiankun Secret Realm, a deafening roar fell from the sky, and the entire cave shook violently.
