Chen Lei continued to walk towards the depths of the forest. Just at the edge of the forest, he discovered rare spiritual herbs such as blue silk grass. He really didn't know what kind of spiritual medicine would be produced in the depths of the forest.
Chen Lei went deep into the forest for dozens of miles and indeed gained a lot.
The magical herbs and medicines here can almost be found everywhere, and each one is extremely rare in the outside world.
In just half a day, Chen Lei had collected several other auxiliary spiritual herbs for refining the Biluo Tongtian Pill. In addition, he also picked many other precious spiritual herbs. This place can almost be said to be a treasure land.
Of course, with such great gains, there must be a considerable degree of risk.
This forest is not only full of dangers, but it is also full of crises. Beside every kind of spiritual herb, there must be a blue spiritual beast guarding it.
Each of these blue spirit beasts is extremely powerful. If they were in the outside world, they would be enough to give headaches to the fourth and fifth level Martial Honor masters.
However, when facing Chen Lei, these spirit beasts could only cause trouble for Chen Lei, and were eventually killed one by one by Chen Lei.
Of course, Chen Lei's killing of these spirit beasts was of great benefit to himself. Not only did he hone his various magic techniques and martial arts, but what interested Chen Lei even more was that after these spirit beasts were killed, they would leave behind a piece of blue crystal.
This piece of blue crystal is made up of the purest spiritual energy and contains a hint of water.
These blue crystals are big and small, some are as big as a washbasin, and some are as small as a fingernail, but without exception, they all contain pure spiritual energy.
Chen Lei went deeper and deeper, and as expected, the closer he got to the deep forest, the stronger the spirit beasts he encountered became. Gradually, the strength of the spirit beasts he encountered had reached the peak level of Martial Honor.
However, this spirit beast at the peak of the Martial Honor level was killed by Chen Lei after fighting with him for a day and a night. In the end, its corpse disappeared, leaving behind a piece of pure blue crystal stone about the size of a room.
After a period of exploration, Chen Lei has come to realize that the spirit beasts here are not real living beings. Instead, they seem to have been refined by some means and are specifically used for cultivation.
Especially the blue crystals left behind after the disappearance of these spirit beasts are simply supreme treasures and extremely rare. They are more precious than the top-level Yuan Crystals.
Not to mention anything else, these blue crystals are enough to give Chen Lei a reason to stay here.
However, as Chen Lei continued to hunt, the blue spirit beasts in this area gradually became scarce, and sometimes he would not encounter a blue spirit beast for two or three days.
Chen Lei knew that enough was enough.
Of course, if he continued to go deeper, he would definitely be able to easily encounter blue spirit beasts. However, each of these blue spirit beasts was extremely powerful, and some had even reached the level of Martial Saint. If Chen Lei encountered such a spirit beast, he would not even have a chance to escape.
Therefore, Chen Lei would never touch such a spiritual beast. He would only move horizontally and search in this area, and would not go deeper, because that would be no different from seeking death.
