'Mana Cultivation Manual' explained the way to sense mana from the surrounding. It seemed that many species had different level of sensitivity towards mana. They had to train to increase their sense and draw mana into their body.
But Raizel didn't have such problem. As a demon lord, his racial advantage gave him highest level of mana sensing capabilities like dragons, fairies etc. And as his body was made from purest form of mana, his compatibility with mana was of the charts.
As soon as he meditated, he immediately sensed mana in the air and inside the earth. Slowly he began to draw them in to his body. All the pours in his body, started sucking mana from the air slowly. He could feel mana entering his body flowing through his veins. Slowly mana was mixing with his blood.
According to the manual, it would take him some time before his body became saturated with mana. The next step was difficult. He would have to convert the mana in to his own demonic essence. Mana present in the air was not part of him. He had to convert them to his own essence to use them.
This was the reason why every individual had different mana signature. And difference between essence of two races was huge. Some have powerful original essence like dragons, demons, fairies, elves etc. Each type of essence had it's own advantages and disadvantage.
The more powerful the essence was, the more mana required to reach the next level. Though dragons and demons were stronger since birth, they had to train harder to reach the next level. But when they achieve it, they are stronger than others.
So Raizel had to spend a month before he was able to fully fill his body to optimum level with his demonic essence. In this month other than increasing his floor's area and goblins, he spent all his time in training.
"Finally, I have completed my first step. Whew, who knew getting stronger was this time taking and boring. If not for the entertainment provided by the fights between goblins and other beasts, I would have given up."
"Hey DAS show me my stats."
[Affirmative]
Oh yeah he had unlocked a new feature in the system. After his training, he bought two skill crystals called 'Appraisal' and 'Analyze'. These two skills cost him 2000DP. But it was worth all the DP.
As the name suggest, 'Appraisal' showed him the details of every item and living beings. Though he had to master it completely before he could get all the details, for now it showed him only the name or race. But with more experience and mastering the skill, more details like what it uses or racial details would be showed.
As for 'Analyze' skill showed him his power level in numeric statistics. This helped him to see how his strength was growing. Combining the skill with 'Appraisal' skill showed him the class of beasts. Like the later, it would show details of other's power level after mastering.
During this month he had tried to use them on different items. He was planning to use them when outside to determine whether someone was a threat or not.

Completing the first step has increased his strength tremendously. It seemed that he was now stronger than F class and was now around lower E class in terms of power level. Due to his lack of fighting experience, he would lose even against a Class F beast.
"It seems having raw power doesn't mean I will win against weaker opponents."
When he had asked DAS about his wining probability against F class beast, her reply made him cry.
[You will be defeated in a minute. A F class beast has more experience than you. You will be alive due to your strong body. But if it is an E class beast, let just hope, it doesn't have any interest in you. Otherwise, you will be dead before you can even blink. Don't look at the beasts killed by goblins daily. They are all weakest among the F class beasts. If a fully matured beast ready to evolve in to the next class intrude the dungeon, all the goblins will be it's food.]
'Yeah the outside world is full of danger and surprises. I will just train even harder and kill some beast nearby before I explore the forest.'
Like that Raizel trained like a madman and finished his first step according to the manual. Next step was more difficult. He would have to refine his heart using his essence and store his essence inside. He would have to be careful or his heart would be blown apart. This was an essential step that is often guided by older generation or you could spent more time to take it slowly.
Also it seemed that if someone managed to complete his refining, his strength would increase exponentially and his lifespan would increase another 100 years in case of humans. Other race will have doubled their lifespan.
Though he didn't have to worry about lifespan being a dungeon lord, it was a good benefit for others. This was another reason why mana cultivation was so widely popular in this world. Who wouldn't want to live longer and get stronger.
In this stage, one thing plays a major role: purity of your essence. The purer your essence is, the stronger your heart would be and the more essence it could store. Also a refined heart would automatically convert mana in to your essence. So stronger heart means stronger recovery of mana.
You could refine and purify your heart later. But it would require many rare herbs and ingredients. You would continue to refine your heart as long as you live to increase it's capability. Slowly a ring would appear around your heart signifying your strength. The no of ring would increase as you get stronger.
According to system, SSS class beings have 9 rings around their heart. Their lifespan was in thousands. They have god like powers. They are only weaker than true gods who have reached the divine level. DAS didn't tell him any more details. It replied he would know once he reached SSS level.
From that day Raizel had another goal, that was to achieve divine level and become truly invincible.
