Back to the underground of the True Martial Palace, Zheng Hao started his endorsement again, in the morning Zheng Hao scanned seventy-three sets of exercises, since he was used to using the martial arts will to manipulate magic, Zheng Hao's reading speed has also become a lot faster, like other disciples, when the grandmaster realm, if you want to mobilize a martial arts will, at least ten copies of loss will be generated, and only after reaching the realm of true martial arts, can the martial arts will not produce a loss of transfer.

Now, after Zheng Hao learns magic, although his will will still be lost, the amount of loss is less than one-tenth, and he can mobilize more than ninety percent of his will at will, whether it is the learning speed or the concentration during the battle, it will naturally improve.

At noon, Mikasa came to deliver food as promised, Mikasa was a little silent, it seemed that Tianxuan said something to Mikasa, fortunately, at least Mikasa would not fall into that strange emotional whirlpool, Mikasa has always regarded Zheng Hao as a teacher, and at the same time her only god, the most trusted person. Zheng Hao carefully pointed out Mikasa's martial arts, and now Mikasa has also broken through to the innate realm, and the foundation is also stable, but the recent practice has been a bit excessive, causing some damage to his meridians, after Zheng Hao pointed out, her advice is not to be too anxious to cultivate internal strength, in recent months, when practicing every day, internal strength should not exceed one hour, and practice martial arts should not exceed half an hour.

A week later, Zheng Hao finally recorded all these martial arts cheats, Zheng Hao's cultivation was also successfully stabilized in the middle stage of the grandmaster, and now the meridians have been filled with true yuan, and he can begin to increase the density of his true yuan.

However, Zheng Hao has become a bit addicted to reading recently, and he has now gone to the miscellaneous book area of the True Martial Palace. Zheng Hao also saw some magic fighting cheats in the miscellaneous book area before, Zheng Hao planned to find out if there was any fire element manipulation magic, not to mention, there were really a lot of trophies from the Zhenwumen over the years, and it really made Zheng Hao discover a fire element manipulation magic, Zheng Hao naturally wrote it down, and by the way, he also wrote down a few more practical fire spells, and what Zheng Hao didn't expect was that he actually found some alchemy books, find a time to study it in the future, take off the Hogwarts school emblem, and you can use it, After all, Zheng Hao is most accustomed to Hogwarts uniforms.

However, Zheng Hao didn't dare to practice spells here, if he burned the book, he would be in trouble. So, Zheng Hao left the True Martial Palace and went to the Ice and Fire Secret Cave. Now that Zheng Hao is in the middle stage of the Grandmaster, he wants to try the fourth layer of the cave again, there is no doubt that after Zheng Hao entered, he felt a lot of pressure again, but it was slightly better than last time, this time he could stand inside and withstand the heavy pressure for three seconds.

In the end, Zheng Hao still returned to the third layer. This Ice and Fire Cave can now be said to be Zheng Hao's territory, and Zheng Hao has changed into a Hogwarts school uniform. Zheng Hao took out his wand and recited the fire element manipulation spell that he saw, there is no doubt that he failed, but Zheng Hao was not discouraged, after all, it was self-taught, the spell was easy to remember, but the trajectory of the wand had to be explored slowly, after all, the pattern of the wand can only provide a reference, everyone's wielding habits, arm distance and other factors will also have an impact, when he first learned the water element manipulation spell, Zheng Hao practiced hundreds of times before he found the correct trajectory of the wand.

This time it's not bad, Zheng Hao only experimented more than fifty times before he found a suitable swing trajectory, but he felt that the power was so small. Zheng Hao experimented two or three times, and each time he felt that he had paid a lot of mental power, but only emitted a point of power.

Zheng Hao took two steps, and then swung his staff again, and suddenly the fire element became very active, Zheng Hao felt that the power he exerted was completely different from just now, not only did it not decrease, but even increased. At this time, Zheng Hao found himself standing on the scorching side of the Ice and Fire Secret Cave, and after thinking for a while, Zheng Hao laughed and said: "How did I forget, elemental magic is made by mobilizing elements with the help of spiritual power, and the surrounding elements will naturally affect the power of magic to some extent. ”

In the afternoon, Zheng Hao did not continue to cultivate, magic only needed to practice chanting mantras and waving staffs, and the accumulation of true yuan in martial arts could only take his time, and he couldn't rush for a while. So Zheng Hao went to the underground base of the laboratory, this time Zheng Hao didn't come for any scientific and technological equipment, but planned to study those alchemy.

Alchemy is a bit troublesome, because it requires specific materials, and some materials are only available in the magical world, last time Zheng Hao collected a lot of good things in the world of Harry Potter, but most of them were books and potion materials, but the alchemy materials were collected very little, mainly because Zheng Hao did not have an alchemy course in the first grade, and Zheng Hao didn't pay attention to it, even the alchemy materials in his hand were just collected when collecting potion materials in the Forbidden Forest.

However, this is enough for Zheng Hao to do an alchemy experiment, which is very interesting, Zheng Hao found the sage stone manufacturing technique on one of the alchemy notes, and it is recorded that as long as you drink the elixir of immortality soaked in the sage stone once a year, you can live forever. Zheng Hao thought it was very interesting, just like the Philosopher's Stone in Harry Potter, so he began the experiment of making the Philosopher's Stone.
