Just when the old man Puke and the others struck hard, while Leng Feng was healing, he also secretly observed the big black bear, although it was still controlling the thunder in the sky, but Leng Feng could see that the natural elements that were like essence were still flying into its body, and then looked at the source of these natural elements, Leng Feng saw that there was no blood in the blood pool at this time, and in the middle of the blood pool, a black hole appeared there, and next to the hole, there was a blood-red key, which seemed to be this key, The hole was opened.

Seeing this, Leng Feng secretly tried the part being treated, and what made his heart flutter was that his limbs finally began to gradually become conscious, and it would not be long before he could regain his mobility.

Finally, when Leng Feng was fully able to control his body, he bounced off the ground and rushed to the center of the pool of blood.

At this moment, the big black bear also discovered Leng Feng's abnormality, at first, the big black bear only had a trace of surprise in his eyes, and then, when he saw Leng Feng rushing towards the blood pool, the big black bear roared, and actually commanded some thunder to shoot towards him, and then, the figure of the big black bear quickly came towards Leng Feng.

Leng Feng had already felt the domineering thunder, but he didn't have the slightest intention of stopping, and rushed into the blood pool, Leng Feng grabbed the blood-red key.

But almost at the same time, Leng Feng suddenly felt a huge force coming from behind him, and at that moment, Leng Feng only felt that there was an extremely disgusting feeling in his chest, and a fishy sweet breath appeared in his throat.

Leng Feng's consciousness sank, and he only felt that his body had sunk somewhere, and then, there was a clattering sound.

Immediately after, Leng Feng felt as if he had fallen on something hard, and fainted.

When Leng Feng woke up from his coma, there was still a hot pain in his back, but fortunately, the injury was not fatal, and he could use the rejuvenation technique to recover. During the recovery period, a thick smell of blood poured up Leng Feng's snort from all around, and Leng Feng knew that this must be the place where the blood flowed through.

After his body regained the ability to move, Leng Feng glanced at the blood-red key in his hand, except for the color of the key, Leng Feng really couldn't see anything else unusual about it.

Seeing this, Leng Feng put the key away, and then began to look around.

This is a stone room, the stone room is not large, and at the top of the stone room, there is a metal round door made of unknown materials, showing a pitch black color. On one side of the wall of the stone chamber, there is a door with a black hole, which leads to no one.

What attracted Leng Feng's attention the most was that on the stone platform in the middle of the stone chamber, there was a dark green crystal in the shape of a flower bone, which was about the size of a human head, emitting a faint green light.

Leng Feng only saw this spar for the first time, and knew that there was a natural element like essence in the body of the big black bear, which came from this spar.

"The Source of Titans, scan this natural elemental core and find out the reserves of natural elements."

Although Leng Feng didn't know what the natural element core was, judging from the previous situation, there must not be too few natural elements in it. The reason why the cold front has been stuck in the second ring druid for so long is because the amount of natural elements in the space is very small, and it is simply not enough to support the amount required for advancement. This natural elemental core just gave Leng Feng an opportunity to advance.

Now the battle above Leng Feng couldn't intervene at all, so after a little silence, Leng Feng had the idea of using this natural elemental core to advance.

"Back to the user, this natural elemental core is rich in natural elemental reserves, but now it is collapsing, and after a day, all the natural elements will disappear."

"What?"

Leng Feng was taken aback, he didn't expect that the natural element in this natural elemental core could only exist for one day.

But this is the case, and Leng Feng has to accept it.

Leng Feng immediately sat down, closing his eyes and feeling the natural elements in the core of the natural elements.

The moment Leng Feng entered the meditative state, in that void, a vast sea of stars like the Milky Way suddenly appeared, although it was composed of green stars, but Leng Feng could see the bright green giant star in the middle of these green stars.

Without the slightest hesitation, Leng Feng began to absorb the free natural elements in the space.

A large number of natural elements entered the meridians of Leng Feng through Leng Feng's breath and skin, and then converged in the dantian, and the halo in the dantian, which was like a young bud, began to gradually solidify, and had the shape of a young bud. With the continuous influx of natural elements, the young shoot began to slowly rise, from a bloated state, to a slender state, and finally grew the first leaf, where the leaf was, the density of natural elements was the highest.

When the third leaf appeared, Leng Feng's dantian suddenly felt a sense of spring, and a thick vitality rippled from the dantian to all parts of the body, making Leng Feng indescribably comfortable.

The appearance of the third leaf is a sign of becoming a three-ring druid, the corners of Leng Feng's mouth are slightly upturned, although he has waited for a long time, but this moment has come, it still makes Leng Feng happy in his heart, and the gloomy mood of so many days has also been slightly relieved.

"Congratulations to the user for improving bioenergy, improving the ability of the Eye of Analysis, increasing the analysis range to 25 meters, and shortening the analysis time by 20%." The voice of the source of the Titan rang out at this time.

At this moment, Leng Feng opened his eyes and groaned, after advancing to a three-ring druid, he could finally do things that he couldn't do before, such as refining high-level potions, and two known three-ring druid techniques.

At this time, Leng Feng naturally didn't think about refining potions, and the two druid techniques, one was the healing touch, and the other was turning into a bear.

Healing Touch is an upgraded version of Rejuvenation Technique, which not only has a much higher healing effect than Rejuvenation Technique, but also restores the target of the Healing Touch on its own, so the caster does not have to pay attention to it from time to time.

This druid technique can be mastered with a little practice. As for becoming a bear, it is what Leng Feng has to consider.

To become a bear, you need to obtain the approval of Spirit Bear before you can perform the druid technique.

The so-called approval of the bear spirit is that when a bear comes to the end of his life, he willingly hands over his pure soul mark to the druid, and once the druid gets this soul mark, he can carry out a preliminary transformation when he advances to the third ring.

Thinking of this, Leng Feng's heart moved, did the bear soul that existed in his body leave a mark?

Then, Leng Feng asked about the source of the Titan, "The source of the Titan, has the soul mark that invaded the soul been left?" ”

"Back to the user, the power of divinity is the soul mark that invades the soul, and after absorption, this soul mark is extremely pure, without the slightest impurity."

Hearing the words of the source of the Titan, Leng Feng was overjoyed, and hurriedly used the method of turning into a bear, when Leng Feng's whole body was covered by a golden bear shadow, a large number of natural elements began to enter every cell around Leng Feng's body, at that moment, Leng Feng's body began to slowly change, and after a while, it turned into a big black bear about one meter five high and three meters long.

Leng Feng looked at his pair of big bear paws blankly, but he roared happily in the stone room, and after the echo of the stone wall of the stone room, there was a deafening feeling, an unprecedented sense of power, coming from all over Leng Feng's body.

Not long after Leng Feng turned into a bear, in the air, there was a sudden chill that soaked into the bone marrow, and Leng Feng shivered after becoming a bear, and that chill was transmitted from the top of the stone room, not that the battle above had changed again, what was it.

Thinking of this, Leng Feng quickly regained his Night Elf state and walked out of the small door.
