As the two behemoths in the field crashed to the ground, Lin Feng came out from behind the big tree.

Taking out the short crossbow in the doomsday watch, Lin Feng fired two arrows at the heads of the octopus zombies in the field. After these days of fighting, Lin Feng's marksmanship has obviously improved a lot, and the two crossbow arrows accurately shot into the head of the eight-clawed zombie.

Not daring to rashly enter the field in front of him, Lin Feng could only test whether the eight-clawed zombie was completely dead. The octopus zombie, which has lost its energy, has weakened a lot in body toughness, so the short crossbow can penetrate its head.

With the boa constrictor in the field also firing two arrows, Lin Feng came to the previous battlefield after confirming that both guys were dead.

At this time, there are still many fires burning in the arena, and the fireball from the octopus zombies has not been extinguished until now.

First, he came to the front of the octopus zombies. The zombies are so powerful, they must have something good in their minds. Lin Feng was going to open the heads of these two zombies to have a look.

The skins of the eight-clawed zombies and boa constrictors were extremely hard. Even though they had lost their energy support, Lin Feng still had a lot of effort to insert the dark iron bayonet into their heads.

A quarter of an hour passed, and seeing the two extra green pills in his hand, one dark and one lighter, Lin Feng was surprised from ear to ear.

Level 5 zombies!

No matter what, Lin Feng never thought that this eight-clawed zombie turned out to be a level five zombie. When I saw this zombie mutate into eight legs, I thought it was a level four zombie. If he had known that the zombies here were level 5, he would have just run this way if he killed Lin Feng. It is said that level five zombies can directly destroy a base, but Lin Feng did not expect to meet them here.

And that boa constrictor turned out to be a level 4 mutant beast, which was as powerful as a level 5 zombie.

Looking at the two green pills in his hands, Lin Feng couldn't recover for a long time.

Lin Feng was really glad that these two guys met together, and for some reason they started fighting. If not, Lin Feng would definitely die if he met one of them alone. With the means of these two guys, Lin Feng is no match for any of them.

It was also because of the fight between these two guys that Lin Feng got a blessing in disguise and got two green pills, one dark and one shallow.

The dark green ones are naturally produced by octopus zombies. Level 4 zombies produce light green green pills. Only level 5 zombies can produce dark green green pills.

And the light green green pill can't actually be called a green pill, but should be called a fourth-level beast soul. The beast soul produced by the mutant beast has the same color level as the zombie, but the mutant beast of the same level is one level higher than the zombie, and the fourth-level mutant beast is equivalent to the strength of the fifth-level zombie. And the produced fourth-level beast souls are naturally no worse than the green pills produced by fifth-level zombies.

Coming to the front of the mandala, Lin Feng carefully picked it and put it into the end-time watch. For the mandala, Lin Feng has experienced countless dangers in the past few days, but it can be regarded as a harvest, and he has obtained things that he could not even imagine before.

Not to mention Lin Feng, the green pill produced by the fifth-level zombies, even the leaders of the major bases have hardly seen it. The fourth-level zombies are okay, some large bases gather some advanced practitioners, and they may kill one or two fourth-level zombies. But the fifth-level zombies and the fourth-level zombies are definitely not the same level. A fifth-level zombie is more powerful than ten fourth-level zombies combined. Therefore, Lin Feng has never heard of a practitioner who can kill level five zombies.

And those advanced practitioners gradually rose to the advanced level after three years of continuous improvement in the end of the world. Even so, it couldn't compete with level 5 zombies. In the apocalypse, every appearance of a level 5 zombie will cause a big wave and spread widely in all major bases.

Right now, the valley is empty, not even a single zombie. After the death of the octopus zombie and the boa constrictor, this is an absolutely safe place.

Without doing anything, Lin Feng simply prepared to absorb the two green pills here.

First, he took out the dark green green pill of the octopus zombie, and without hesitation, Lin Feng swallowed it in one gulp.

Unlike the green pill produced by the fourth-level zombies, after swallowing this green pill, Lin Feng didn't react at all.

Could it be that the level difference is too big, and there is no reaction after eating?

Seeing this situation, Lin Feng was a little annoyed, thinking that this green pill was eaten for nothing, right?

But at the next moment when Lin Feng was thinking about it, a monstrous energy rushed straight to the soul of Lin Feng's mind. Lin Feng felt his head was about to explode, and he couldn't help but groaned.

The powerful energy impact suddenly inflated the soul in Lin Feng's mind. Lin Feng could clearly hear a rattling sound in his head, which was the sound of his soul expanding. With the swelling of the soul, Lin Feng felt that the bones of his whole body were trembling.

At the same time, the soul in Lin Feng's mind trembled frequently. If Lin Feng could see the situation in his mind, he would find that the second shackle was gradually forming in the soul.

Lin Feng who devoured the green pill actually started to undo the second shackle.

The function of the shackles is to increase the ability of the practitioner. After opening the first shackle, the cultivation level of the practitioner will be about 10% higher than that of the same level. After awakening the second shackle, the ability will be improved. at twenty percent. That is to say, the cultivators who have awakened the second shackle are about 20% higher than ordinary cultivators in terms of cultivation.

Don't underestimate these 20%, in actual combat, more strength means more self-protection ability. Under the same conditions, practitioners who have awakened the shackles of the soul still have a great advantage.

With the awakening of the shackles of Lin Feng's soul, coupled with the powerful energy in the green pill produced by the level 5 zombies, Lin Feng was finally promoted to a level 5 cultivator. And Lin Feng came to the end of the world, but only for a month.

After the upgrade, Lin Feng looked at the doomsday watch, and found that his combat power had suddenly risen to 3500, which was almost double what he had before the upgrade. Lin Feng has improved so much after only swallowing one green pill, which shows how powerful the energy of the green pill is in the brain of the fifth-level zombie.

And this is not counting the fighting power of Lin Feng's awakened shackles. With the 20% shackle bonus, Lin Feng's fighting power can even reach more than 4,000. Coupled with the identity of the round dancer and his own mutant blood, Lin Feng's cultivation has even reached the standard of quasi-level 6. It's just that the Doomsday Table calculates combat power through spirit and physique, and other factors are not counted by the Doomsday Table.

After being promoted to level 5 cultivator, Lin Feng did not stop, but looked at the level 4 beast soul produced by the level 4 mutant beast in his hand. The green pill just now can bring such an improvement to Lin Feng, so Lin Feng is looking forward to what changes the fourth-level beast soul, which is the same level as the fifth-level zombie green pill, will bring to Lin Feng.
