After everyone dispersed, Lei Xiaotian returned to the Heavenly Wolf Palace, practiced martial arts in the courtyard for a while, and then returned to the room to rest. Lei Xiaotian has been in retreat for more than three months, and he is a little tired, although Lei Xiaotian meditation can replace sleeping, but psychological exhaustion is still inevitable.

For the next period of time, Lei Xiaotian summoned the orange eagle every day, and he was paying attention to the battle situation in Xuanyang Mansion and Tianyin Mansion, but the battle situation between the two mountain gates tended to be stable, and the two sides were originally of equal strength, and they had been attacking and attacking on the border, but they did not achieve a breakthrough victory. Although both sides suffered heavy casualties, neither had an absolute upper hand.

In Tianyun City on the border of Xuanyang Mansion and Tianyin Mansion, the two sides launched a fierce competition, according to reliable sources, both sides have several Douzong level powerhouses died on the battlefield, the battle is quite fierce, from the intelligence of all parties, Lei Xiaotian estimated, these two sides want to divide the winner, it will take at least one or two months, so Lei Xiaotian decided to enter the 100,000 miles of barren mountains again during this period of time, and cultivate for a period of time, now Lei Xiaotian has been able to cast a seventh-level undead magic, Lei Xiaotian wants to study the eighth-level undead magic in the 100,000-mile barren mountain, any magic to the eighth level or above, when it is released, it will produce a strong aura, and Lei Xiaotian didn't want others to know that he had a double cultivation of magic and martial arts, so he could only enter the 100,000-mile barren mountain to practice magic, the most important thing was that Lei Xiaotian faintly felt that his magic cultivation was showing signs of breakthrough, and Lei Xiaotian also wanted to enter the 100,000-mile barren mountain to see if he could break through again.

Now, Lei Xiaotian's Dou Zhuan Star Shifting Divine Skill has broken through to the eighth level, and his strength is equivalent to one or two Dou Zun, but his magic cultivation is only the peak of the junior demon master's low level, and his strength is only equivalent to three or four Dou Zong, all Lei Xiaotian wants to go to the 100,000 miles of barren mountains to practice magic for a period of time, so as to shorten the gap between his fighting spirit and magic cultivation. So after Lei Xiaotian arranged the affairs of the Heavenly Wolf Gate, he once again left the Golden Eagle to preside over the overall situation in the Heavenly Wolf Gate, and he and Xiang Lang set off from the North Wolf Mountain together and walked towards the depths of the 100,000-mile barren mountain, the bloodthirsty flying wolf was still the same as last time, staying in the North Wolf Mountain, one is to facilitate the command of the demon wolf group, and the other is to facilitate Lei Xiaotian to communicate with the people of the Heavenly Wolf Gate who stayed behind after leaving the Heavenly Wolf Gate, Lei Xiaotian and the bloodthirsty flying wolf have a soul connection, no matter how far Lei Xiaotian goes, he can communicate with the bloodthirsty flying wolf with his heart。

After Lei Xiaotian set off from the North Wolf Mountain, he has been riding on Xiang Lang's back, and let Xiang Lang fly high in the air to avoid letting adventurers on the ground discover his tracks. When Xiang Lang followed Lei Xiaotian out of the forbidden land of the gods, he was only a seventh-level peak demonic beast, and his strength was equivalent to that of the Eighty-Nine Heavy Dou Sect, but during the period of coming to the Heavenly Wolf Gate, after Lei Xiaotian fed him with pills regardless of the cost, Xiang Lang at this time had broken through to the eighth-level junior demonic beast, which was a great progress. At this time, Xiang Lang's flying speed was extremely high, and in three or four days, Xiang Lang flew to the valley where Lei Xiaotian retreated and practiced magic last time, which was close to the depth of 100,000 miles of barren mountains and 10,000 li, and almost no adventurers set foot on it, and some were only some seventh-level or a small number of eighth-level demonic beasts, so in this valley, Lei Xiaotian's cultivation was guarded by the eighth-level demonic beast Xiang Lang, and it would not be disturbed.

After Lei Xiaotian came to the valley, he re-settled in the cave where he lived last time and began to cultivate. Like the last time Lei Xiaotian's cultivation method, Lei Xiaotian first meditated, stabilized his mind, and adjusted his mental power, and when all aspects of his body were completely adjusted to the best state, he began to continuously perform level 8 or above undead magic in the valley.

It is quite difficult to cultivate eighth-level magic, and after five or six days of continuous attempts, Lei Xiaotian finally succeeded in summoning the eighth-level undead creature Death Knight, and when he saw the death knight he had summoned, Lei Xiaotian showed a satisfied smile. The last time he fought with the intermediate necromancer in Huoyun Villa, the death knight summoned by the necromancer made Lei Xiaotian suffer, and Lei Xiaotian also deeply realized the strength of this eighth-level undead creature death knight, and after looking at the death knight he summoned, Lei Xiaotian knew that his magic strength should have broken through to the peak of a junior mage at this time. As long as you work hard to cultivate, you can break through to the intermediate magister, and now your strength in magic alone is equivalent to the Nine-Fold Dou Sect, with undead magic, as long as there is enough time, it is an ordinary one-level Dou Zun, and you can barely cope with it with magic alone.

In the next period of time, Lei Xiaotian began to practice magic frantically in the valley, constantly releasing magic every day, and went to meditate and recover after consuming his spiritual power. A long time ago, Lei Xiaotian had discovered that whenever he cultivated when he was exhausted, whether it was fighting qi or magic, he would improve rapidly.

A month has passed, and at this time, Lei Xiaotian has mastered several eighth-level undead magic, but it is only able to summon eighth-level primary-level undead creatures, and Lei Xiaotian knows that as a junior magician, he can't summon undead creatures above the eighth-level primary. After all, the junior demon master is only equivalent to the level of the Dou Zong, but he can summon an undead creature with a strength of one or two Dou Zun to help him fight, which is enough to defy the sky, if he is allowed to summon an undead creature in the middle of the eighth level, it will not let other cultivators live, it is estimated that the people of the whole world will change to undead magic, at this time, Lei Xiaotian obviously felt that his spiritual power had reached a calm, and he had already touched the barrier of breakthrough, so Lei Xiaotian used his mind to inform Xiang Lang to protect himself, and then walked into the cave, preparing to retreat, meditating on spiritual power, and striving to break through to the realm of intermediate magicians。

After coming to the cave, Lei Xiaotian first took out a jade pill from the space ring, this jade was filled with an elixir refined by the Heavenly Machine Law God, called Pozun Dan, this pill is the eight-grade peak pill, which is one level lower than the Divine Transformation Saint Pill that Lei Xiaotian gave to Xiang Ying for Xiang Ying to break through last time. The Divine Transformation Saint Pill is an elixir for people who are about to break through to the Dou Sheng, or who are about to break through to the Great Demon Guide level, to help them break through. However, the Broken Zun Pill is specially given to people who want to break through to Douzun or Intermediate Magisters to help them break through. And Lei Xiaotian is in this state right now, taking this elixir, just to make the best use of it.

After sitting cross-legged, Lei Xiaotian stabilized his mind for a moment, and then opened the jade, and immediately the jade incense emanated from the tempting medicinal fragrance.
