The Holy Jade Jane recorded a total of one exercise, two major battle techniques, and three holy arts.

The exercise is called "The Book of Cold Heaven", and after reading it roughly, Cheng Bo can judge that this is an exercise that surpasses the level of the Holy King, and for a while, he was a little surprised, and the Winter Emperor just accepted him as an apprentice and actually taught him such a powerful exercise.

As for the combat skills, one is the sword technique, and the other is the palm technique, both of which are combat skills that match the "Cold Heaven Sutra".

There are also three holy arts, which are also extremely extraordinary, one is for the body method, one is for the attack, and the last one is for the hidden class.

It took a few hours for Cheng Bo to thoroughly understand these martial arts and holy arts, which can be said to have benefited a lot.

Subsequently, he spent two more hours integrating the "Cold Heaven Sutra" into his "Ten Thousand Saints".

Then, he began to cultivate.

"Huh!"

With his cultivation, he noticed that this side hall was very extraordinary, his cultivation was extremely smooth, and the speed was also extremely fast, and his divine thoughts swept over, and he found that the entire side hall was arranged with extremely complicated formations inside and outside.

Within half an hour, the holy power in his body had transformed into a new holy power, and its essence was even higher.

"Good!"

Cheng Bo smiled slightly and began to study combat techniques and holy arts.

The two major battle techniques and the three holy arts, it took him a total of three days to cultivate, and all of them were cultivated.

It went unexpectedly well.

Just when Cheng Bo was about to continue his cultivation, a slender and tall figure walked in, it was the Winter Emperor.

"I've seen Shizun!"

Cheng Bo hurriedly got up and saluted.

"Didn't you say that you don't understand the place to ask the teacher?" said the Winter Emperor with some displeasure.

"No, Master, I didn't have a problem!"

Cheng Bodao.

"Didn't encounter any problems?" the Winter Emperor was stunned: "Can you cultivate the exercises, how many combat skills and holy arts can you cultivate?"

"It seems to be all done!"

Cheng Bodao.

"Impossible!"

His Majesty the Winter Emperor realized that although what she had taught to Cheng Bo was not the most advanced martial arts and holy arts, it was also not something that ordinary saint kings could easily understand.

"Don't dare to deceive the master!"

"In that case, you can use your newly learned combat skills and holy arts to fight with your teacher!"

The Winter Emperor thought for a moment.

"Yes!"

As soon as the words fell, Cheng Bo disappeared directly in place, and the hidden void disappeared, and then, several foot-long ice arrows suddenly appeared behind the Winter Emperor.

At the same time, crystal snowflakes floated in the main hall, and then Cheng Bo's figure suddenly shot out from a snowflake, and the silver sword light poured down, completely enveloping the Winter Emperor.

"Brush!"

The Winter Emperor disappeared in place, and Cheng Bo's attacks all failed.

"Brush!"

Cheng Bo also disappeared, reappeared, and came to the Winter Emperor again.

"Go back!"

The Winter Emperor flicked his hand, and Cheng Bo rolled and flew back.

"That's it!"

The Winter Emperor raised his hand and looked at Cheng Bo with bright eyes: "You have really mastered the combat skills and holy arts in the Jade Jane, and you are quite proficient in using them!"

In the round of attacks just now, Cheng Bo showed a total of three holy arts and two combat skills.

Originally, the Winter Emperor also planned to suppress the second stage of the Holy King, so that this apprentice could eat and stake, but she didn't expect that in the face of Cheng Bo's wonderful attack, she actually had a feeling that she couldn't resist, so she could only dodge and avoid it, otherwise, she would definitely make a big fool.

"Thank you for the compliment!"

"Good, good!"

The Winter Emperor laughed: "Your talent is beyond the imagination of the teacher, and you can inherit the mantle of the teacher!"

"Take it!"

The Winter Emperor threw out another jade slip, and then floated away.

Back in the other palace, the Winter Emperor couldn't help laughing again, and then his eyes turned cold: "Slut, you are better than me in everything, but your ability to accept apprentices is not as good as mine!"

Inside the side hall.

Cheng Bo's divine thoughts probed into the second jade slip given to him by the Winter Emperor, which contained one technique, two combat techniques, and two holy arts, judging by his eyes, these five secret books were many times more powerful than those recorded in the previous jade slips.

There was nothing to hesitate about, he carefully pondered this exercise, and then once again integrated it into the "Ten Thousand Saints' Formula".

And it took an hour, and the holy power in the body was transformed again.

"Idiot, why don't you use the pill I gave you!"

Suddenly, the voice of the Winter Emperor sounded in Cheng Bo's ears.

"Yes, Master!"

Cheng Bo hurriedly took out the pill bottle, and found that there were three dark blue pills with a strange fragrance inside, and just by taking a sip of the medicinal incense, he felt that his holy power had become a lot more active.

With a thought, Cheng Bo took out a pill and took it.

The elixir melted in his mouth, and immediately, a cold medicinal power instantly melted into his limbs and hundreds of remains, and even the sea of consciousness was penetrated.

"Snort!"

Like boiling water poured on coals, Cheng Bo felt that there were puffs of black smoke coming out of his body, holy power, and even his soul.

This black smoke is rotten and foul, and there is a faint grimace struggling and roaring in it, this grimace is unusual, constantly rushing towards Cheng Bo, as if it wants to re-enter his body.

"...... this?"

Looking at the black smoke and the grimace in the black smoke, Cheng Bo was very puzzled.

The Winter Emperor's voice sounded at the right time: "What you see is the strange material that was incorporated into your body when you cultivated, this strange material is imperceptible to ordinary people, even the Saint King-level creatures can't detect it, but it is extremely terrifying, it can corrode your lifespan and vitality, why do you say that the Saint Emperor-level and even the Saint Emperor will die of old age, it is all caused by this strange substance!"

"Then this elixir can completely remove strange substances?" asked Cheng Bo.

"Think beautifully!"

The Winter Emperor sneered: "Even if you can empty the strange substance for a while, as long as you live in the Holy Realm, the strange substance will continue to penetrate into your body!"

"I see!"

Cheng Bo nodded and continued to pay attention to the situation in his body.

In an instant, half an hour passed, and the black smoke coming out of his body became lighter and lighter, but when the medicinal power was exhausted, the strange substance still hadn't been cleaned up, but Cheng Bo felt inexplicably relaxed.

It's as if something inside the body has been excreted.

Cheng Bo did not take the remaining two pills, but put them away, and he planned to give them to his relatives to use.

Then, Cheng Bo entered the practice again.

This time he practiced, his speed was even faster, and at the same time, he did not hesitate to take out medium-grade holy crystals, all kinds of holy medicines, and pills for cultivation.

A month later.

His Golden Sacred Realm Law was directly promoted to the third stage of the Saint King, leaving only the Law of the Wood Sacred Realm and the Law of the Earth Sacred Realm still staying in the second stage of the Saint King.

Subsequently, he spent another three days cultivating the combat skills and holy arts newly taught by the Winter Emperor.

The Winter Emperor, who was secretly paying attention to this scene, couldn't help but secretly call out the demons, and then burst out laughing uncontrollably.

"Whew!"

Cheng Bo couldn't help but exhale a breath of turbidity.

Suddenly, he felt a movement coming from inside the Storage Sacred Ring, and in an instant, he remembered the hatching bird, and hurriedly took out the piece of ore.

Divine thoughts probed into it, and as soon as they touched each other, there were thoughts of intimacy and joy.

At the same time, the little bird has grown to the size of a fist, and its feathers are black, but it exudes a natural luster, and the runes on its body are also clearer.

"Hungry!"

The little bird is delivering a message to Cheng Bo.

Cheng Bo hurriedly took out a large amount of Dark Saint Crystals, shattered them all, and then introduced Dark Saint Qi into the ore.

"Whoosh!"

The figure flashed, and the Winter Emperor reappeared.

Looking at the ore in front of Cheng Bo, she was shocked and asked, "This is the egg of the Dark Holy Bird, where did you get it?"

"I've seen Master, this ore egg was bought by me in the trading area in Fengyuan City!"

Cheng Bo said truthfully.

"You...... I don't know what to say about you as a teacher!" said the Winter Emperor in an extremely complicated tone.

Cheng Bo was taken aback: "Master, is there anything wrong with this ore egg?"

"No!" the Winter Emperor shook his head, "Do you know where this Dark Sacred Bird came from?"

"I don't know!"

Cheng Bo shook his head.

The Winter Emperor continued: "There is only one Dark Holy Bird in the entire Holy Realm, when its lifespan is exhausted, it will seal itself in the Black Nightmare Mine, and after countless years, it will be reborn in the Black Nightmare Mine, however, it will not have the memory of its previous life, but its strength will grow extremely fast, and it will soon resume the cultivation of its previous life, as a teacher, remember that the last time the Dark Holy Bird appeared was more than three million years ago, and the cultivation of that Dark Holy Bird has reached the peak of the Holy Emperor!"

"So, didn't I get a pet with the potential to reach the peak of the Holy Emperor?"

Cheng Bo was pleasantly surprised.

"How can it be so easy!"

The Winter Emperor shook his head: "It's true that it wants to recover its previous life cultivation relatively quickly, but it needs a large number of dark holy relics, and those dark holy relics are all extremely precious, only some Holy Emperors and Holy Emperors have collections!"

As he spoke, the Winter Emperor had an extra black diamond-shaped crystal in his hand: "This is the dark celestial crystal in my collection, you can absorb it, you can let it hatch in advance, and once it is born, it will also have the strength of the Saint King level!"

"Thank you, Master!"

Cheng Bo thanked him again before taking over the Dark Sky Crystal.
