For the next period of time, Chen Lei was constantly attacked by monsters.
The Purgatory Battlefield is worthy of its reputation. The number of monsters here is indeed astonishingly large. The black beetles, earthworm-like monsters, etc. that Chen Lei had killed before were only on the outskirts of the Purgatory Battlefield, and the number was not too large.
However, when Chen Lei encountered powerful monsters such as magic tigers, magic wolves, and magic leopards, their numbers had begun to increase sharply, and most of them were at the peak of the second level of the Yuanhun Realm, which brought tremendous pressure to Chen Lei.
If it were an ordinary strong man, he would definitely not be able to resist the attack of so many monsters. He would either escape or be killed.
But Chen Lei is different. Chen Lei has a battle armor that is integrated with magic treasures. He can continuously absorb magic energy and transform it into spiritual energy. In this way, he doesn't worry about excessive consumption of spiritual energy. In this way, he can kill monsters continuously and achieve the purpose of honing himself.
Indeed, this kind of high-intensity, high-density and high-risk battle has made Chen Lei's progress astonishingly fast. Chen Lei's cultivation has reached the peak of the ninth level of the Nascent Soul Realm. He is only one step away from breaking through to the Yuanhun Realm.
During this period of time, Chen Lei killed at least eight hundred monsters, which is an astonishing number.
In fact, those strong men who were sent to the Purgatory battlefield, no matter how high or low their cultivation level was, had no way to kill so many monsters in such a short time.
Chen Lei's gains from killing so many monsters were huge. Not only did he obtain nearly a thousand magic crystals, but he also obtained two magic treasures.
Although the chance of dropping this magic treasure is surprisingly low, it is normal for Chen Lei to drop two magic treasures after killing so many monsters.
Chen Lei integrated these two magic treasures, one into the Black Lotus Armor, and the other into the Black Lotus Sword, which doubled the speed at which he absorbed and refined the demonic energy in the Purgatory Battlefield.
In the end, Chen Lei reached the peak of the Nascent Soul Realm and could not go any further. He had to find a way to break through to the Yuanhun Realm.
Afterwards, Chen Lei left this place and rushed to a black market in the Purgatory Battlefield.
In the Purgatory Battlefield, in addition to the Demon-Slaying City, there are several black markets outside the Purgatory Battlefield. The things in these black markets are even richer and rarer than those in the Demon-Slaying City.
The reason why Chen Lei knew about these black markets was because he searched them from the souls of two werewolves.
The reason why Chen Lei wanted to go to the black market was mainly to see if there were any elixirs or methods in the black market that could help him break through to the Yuanhun realm.
Chen Lei had tried many times to break through to the Yuanhun realm before, but unfortunately, he failed every time and there was no way to break through.
Chen Lei himself also found the reason.
There are now nine Nascent Souls in his body. The nine Nascent Souls resonate with each other and are extremely powerful.
However, when he broke through to the Yuanhun realm, these nine Yuanyings actually became obstacles for him to break through to the Yuanying realm. Even though his cultivation was sufficient, he could not allow the nine Yuanyings to break through at the same time.
If the nine Nascent Souls cannot break through at the same time, then the final result will be failure.
Because of this, Chen Lei even suffered backlash several times. Fortunately, he stopped forcing a breakthrough in time, otherwise, he would probably have disintegrated.
