Martial arts in the world are roughly divided into four levels.
Basic, advanced, first-class, legendary.
Among them, the legendary secret books are so rare that they are basically unpublished secrets, and the first-class martial arts are already the sect-suppressing martial arts of many first-class masters in the world.
The "Chasing the Stars and Chasing the Moon" skill that Cao Su was looking for was the Zhaoxia Sect's Zhenzong martial arts, which was the best in the world.
It's a pity that he couldn't find someone to write the papers in the palace.
Finally, through the wooden stick tool man, I took away a copy of "Spiritual Snake's Breath Condensation Technique" and a copy of "Purple Sky Breaking Thunder Knife"
Cao Su is about to get started with the Thunder Sword recently. Once he gets started with the Thunder Sword, the Thunder Sword and the Nilong Sword may be combined to create a new sword technique. He is not sure whether the new sword technique can reach the first-class threshold, so he keeps a similar knife with him.
Law.
Cao Su had heard of this "Purple Sky Thunder-Breaking Sword" before. It was the secret knowledge of the Lei family in Jianzhou eight hundred years ago.
Later, the Lei family encountered changes and split into several branches. Among them, the Jianzhou Lei family mainly practiced swordsmanship, while the Xizhou Lei family was a family of alchemists. The last Lei family lived in the north, and is said to be in Youzhou.
, became the founder of Youzhou Fenglei Sect.
Cao Su thought about it carefully and finally took away the two first-class secret books that were most suitable for him at this stage.
As soon as the stick man finished his selection, he drove Cao Su out like a plague.
Secrets given by the royal family will not be copied.
The royal family collects secret books from all over the world. The speed of purchasing secret books is much faster than the speed of giving away secret books. Under normal circumstances, it can collect at least hundreds of secret books a year, but there are too few important officials who can actually receive gifts.
Cao Su was the first high-ranking official to receive a gift this year.
As if he had found a treasure, he put the two collector's edition secret books in his arms, and then headed to the Thunder Prison with Xun Zhi.
"Start practicing in Thunder Prison today?"
"Yes, I started practicing today. I heard that Thunder Prison is a treasured place for body training. Brother, I am not bragging. My horizontal training skills are also good in the world. If I can get training from Thunder Prison, I will definitely be able to practice my physical body.
We can go further.”
Cao Su's aura was strong and masculine, which was very different from the femininity in the palace. Xunzhi was naturally envious of him.
But he can only be envious. He has lost the most precious thing in his body. This thing cannot be practiced. It is an eternal truth that it is easier to arrange flowers than to plant trees.
He took Cao Su towards the Thunder Prison.
Lei Prison, also known as Lei Chi, is a secret realm set up in the palace by the Wen family after they established the Qianyuan Empire.
It is said that it was specially created by Emperor Qianyuan Gaozu, who found many top boundary stones to suppress the secret realm. The secret realm is full of vitality and is most suitable for martial arts practitioners to improve their physical body.
Cao Su has been coveting the Thunder Prison for a long time, but unfortunately the Thunder Prison is only open to the clan.
If it hadn't been for the death of the late emperor, the current weakening of the royal family, and Yu Wenji asking Cao Su to go to the north to suppress the rebels, Cao Su would not have had the opportunity to enter the Thunder Prison to practice, no matter how great his achievements were.
There are only one record of people with other surnames entering Lei Prison to practice in the Qianyuan history.
And two of them are princes-in-law, half of the Wen family.
The Thunder Prison is located deep in the palace. Xunzhi led the way. The group of people walked deeper and deeper, and soon felt a slight chill.
"We are almost reaching the Cold Palace, and the Thunder Prison is within the Cold Palace."
Because it is like a prison, the Thunder Pond is also called the Thunder Prison. Over time, many people confuse the Thunder Prison with the Cold Palace. Those who leave the Cold Palace have to go through the Thunder Prison first.
In fact, the Thunder Prison is a secret realm. People who leave the Cold Palace do not need to step into the Thunder Prison, they can just pass by.
The two of them walked along the deep corridor of the palace. At this time, the deep palace was sparsely populated, and the patrolling Yulin Army was rarely seen.
"This place is a deep palace. Many of the late emperor's concubines and empresses live here. Don't run around. Breaking into the empress's palace is a death penalty!"
Xunzhi specially warned Cao Su.
Not long after, a group of Yulin troops followed Cao Su into the edge of the Cold Palace.
"Don't worry, why would I go to the queen's palace?"
Cao Su is not interested in the empress. He just wants to go to the Thunder Prison, use up all the demon clan essence and power realm essence left in his body, deduce his own sword skills, and practice the star-catching skill, and step into the world.
The realm of the third grade.
Come to think of it, there are quite a lot of things going on, and I don't know if Lei Yu's energy is enough for him to squander.
In the Yinfeng Cave before, he almost squeezed the entire cave dry.
.........
.........
"Stop!"
Suddenly, a huge wall appeared.
A general in black armor appeared in front of Cao Su. At the same time, there were several vague auras of power scattered around, vaguely trying to surround Cao Su.
Xunzhi stepped forward and handed over the emperor's token: "By the emperor's decree, General Cao Su of Pingxi is sent to Lei Prison for training. General, please let him go."
The black-armored general is very cold and has an extremely strong aura.
Cao Su was secretly surprised that he was actually another second-level master.
As expected, the palace was heavily guarded. Crouching Tiger, Hidden Dragon, and rare top-level masters began to appear one after another.
And this black-armored general looks quite young.
"Come with me."
He accepted the token, spoke concisely and concisely, and led Cao Su into the deep palace.
We were already very close to the Leng Palace. At the same time, a purple light pillar appeared at the entrance to the New Palace. This light pillar was covered with thunder, and it flashed with majesty.
"This is the out-of-boundary stone. If you can't hold it anymore, just crush the out-of-boundary stone and come out of the thunder realm."
The black-armored general handed a dark stone to Cao Su. Cao Su took a look and saw that it had the same effect as the boundary-breaking seal he got from Chen Zhen, but it was a one-time use.
The boundary-breaking seal is of little use to Cao Su, because there is no boundary for him to break.
As for the so-called "passing through the wall", he can do it by just dodging.
"Normally, cultivation at the middle level of strength realm can last for twelve hours at most."
The black-armored general said this, and then left here, just like a procedure, and continued to squat at the entrance of the deep palace.
Cao Su could feel that there were still several eyes staring at him, and the aura lock did not relax at all. If he dared to mess around, he would soon receive a fatal blow from the masters in the palace.
He nodded to Xunzhi, turned around and stepped into the pillar of light.
In an instant, the flashing thunder in front of him was like a weak electric current, passing through his body.
His clothes were scorched black by the electricity, and the world was spinning in front of him.
When I could see again, I entered a foggy space.
There are flashes of lightning in the fog, penetrating the space from time to time.
The entire space was not large. Cao Su tried to take a few steps forward, and the mist took the initiative to bypass his body and disperse. As soon as it dispersed, weak thunder appeared in front of him.
When he moved, the thunder also moved, and struck the back of his hand with a "pop" sound.
The back of his hand suddenly became slightly numb, but it was not enough to break Cao Su's defense.
Cao Su took a closer look and saw that on the back of his hand that was hit by the thunder, a circle of dark lake spread out. Then that area seemed to be equipped with a vacuum cleaner, and countless mists of vitality rushed into him.
's back.
"Bitter first, then sweet, what a good mechanism!"
Cao Su immediately understood the principle of Thunder Prison training.
He immediately stopped walking, found a random place in the space, and began to practice hard in seclusion.
As soon as the internal energy in the body was released, the body became slightly heated, and a small amount of weak thunder immediately gathered around it. After these weak thunders gathered together, they quickly became huge.
Then a "fastest-growing" thunder suddenly struck Cao Su.
Cao Su's thoughts moved slightly, and he pulled the thunderbolt and hit him on the back.
Suddenly the clothes on his entire back were torn to pieces, and the thunder struck his body as strong as steel. There was no big reaction, leaving only a small black spot. Cao Su used his inner strength to practice again, and the space
The vitality inside started to boil like boiling water.
“Great place, great place!”
Cao Su was overjoyed and frantically absorbed the vitality, turning it into inner energy and continuing to seduce the thunder to kill him.
The more he choked, the more his body seemed to have opened up its veins, absorbing vitality unscrupulously and turning it into a rolling internal energy in his body, gradually pushing his realm forward.
With a thought in his mind, he used the essence of force realm once.
Under the force realm essence, the vitality in the entire space was stirred even more fiercely. The thunderbolts gathered around Cao Su as if they were free of charge, and struck Cao Su one after another.
The fog in the space was so chaotic that even the thunder beams from the outside world trembled slightly.
Just like that, Cao Su suddenly opened his eyes.
He stood up in great surprise. At this moment, his body was completely smashed by thunder, leaving only two collector's edition secret books, which were protected by his inner strength and not destroyed.
The reason why he was surprised was because a gust of fragrance suddenly drifted in front of his eyes.
A woman with black hair hanging down her waist and no hair appeared in front of him.
She is very young, has a beautiful face, skin as smooth as gel, long and round legs, and a slender figure.
Can men and women bathe together in this thing?
Cao Su's eyes widened, and his fiery gaze was not concealed at all. He would not suffer any loss anyway.
"You can't practice like this for a long time, because all you absorb are Yang Lei, and Yang Lei enters the body. Within twelve hours, you must find a way to break it."
When the woman saw that Cao Su was so undisguised, she felt a little angry, but she was very deep in the city and could not hide it quickly.
There is always a natural sense of nobility on his face, and he looks like someone who has been in a high position for a long time.
Cao Su was shocked. Did he really meet some empress?
You’re already a queen and you’re still working so hard to come here to practice?
The late emperor was a beast, how could he kill him at such a young age?
Cao Su thought for a while and coughed dryly: "Girl, I came to this bathroom first, why don't you change to another one?"
The woman ignored Cao Su's nonsense and moved forward, getting closer and closer to Cao Su.
There is almost no distance between the two.
Cao Su was too tall, so she could only raise her head and say in the calmest tone:
"I have been in the body for twelve hours with the Yin thunder, which is just enough to neutralize the Yang thunder in your body. You and I can practice together to help me develop the Divine Thunder Immortal Body."
Cao Su also raised his head and frowned: "Girl, don't make trouble, I'm here to practice hard."
