In his eyes, the huge vines that originally covered the whole circular space disappeared, leaving only withered stumps and fallen leaves all over the ground.

"Fei, did you kill it?" Looking at everything in front of him, Li Feng felt a little incredible.

He knew in his heart that the strength of the vine monster was far better than himself and Duan Fei. Let alone fighting alone, even if they combined, they were not necessarily its opponent. But judging from the current situation, it seems that Duan Fei killed it alone. What's going on?

Li Feng racked his brains. For the memory of this period, his brain is still blank and can't remember anything.

Noticing Li Feng's suspicious look, Duan Fei laughed and quickly explained, "brother Li, you forgot that when we were just found, you were accidentally hit by the tentacle on the monster's body, and the nerve paralysis poison inside made you faint!"

"Really?" Li Feng flashed a suspicious look in his eyes, stared at Duan Fei's face and asked, "did you kill this monster alone?"

Being stared at by Li Feng's puzzled eyes, Duan Fei felt a little blushed, but because of the evolutionary tree, he certainly couldn't tell the truth. He smiled awkwardly and said, "yes, to tell the truth, if it was a frontal battle, how could I be its opponent? The reason why I could kill it completely was because I found its weakness!"

"Weakness, what weakness!" Li Feng's eyes lit up and asked quickly.

"Cough!" Duan Fei coughed and then said, "brother Li, do you remember the red fruit we saw when we came to the monster?"

"Fruit?" Li Feng was slightly stunned. He thought about it carefully for a moment and murmured, "it seems that there is such a fruit... Ah Fei, what do you mean..."

Looking at Li Feng's suddenly enlightened look, Duan Fei was relieved and said, "yes, that fruit is actually the core of the monster. I destroyed the red fruit and killed the vine monster!"

"So it is. The fruit is exposed. With ah Fei's strength, it's really not difficult to destroy it!" Li Feng nodded and finally understood.

Seeing the doubt on Li Feng's face slowly fade away, Duan Fei quickly stopped the topic and turned to the wooden box.

Destroying fruit is easy to say, but it is difficult to do. Li Feng was guided by Duan Fei's words and preconceived that Duan Fei destroyed the fruit, which killed the vine monster.

In fact, in the face of so many vines with poisonous thorns, it was extremely difficult for Duan Fei to move forward for half a minute, not to mention breaking through to the body of the vine monster and destroying the fruit. What's more, even if Duan Fei successfully breaks through the monster's body, the fruit grows on the wooden box with countless red tentacles inside. With these tentacles, Duan Fei can't hurt half of the fruit.

Duan Fei walked in front, and Li Feng followed behind. They soon walked to the wooden box.

Looking down, the wooden box originally wrapped by countless vines has regained its original shape, and in the wooden box, the blood red fruit has disappeared, and a huge crack appears in the center of the wooden box, almost cutting it in half.

After seeing the fruit disappear, the last doubt in Li Feng's eyes finally dissipated. It seems that ah Fei really destroyed the fruit, which killed the vine monster.

When the fruit disappeared, there were only two ugly slender iron rods left in the dilapidated wooden box.

Duan Fei stretched out his hand, picked up an iron bar and looked at it carefully.

The dark golden iron bar is covered with simple and mysterious patterns. These patterns gather in the center, and then spread slowly towards both ends like dyes dripping into clear water.

"What is this?" Looking at this strange iron bar, Duan Fei's eyes flashed a look of doubt.

Although this iron bar looks well made, Duan Fei doesn't feel any energy fluctuation from it.

"These patterns!" Li Fengjing stared at the two iron bars, and a look of doubt flashed in her eyes.

"Brother Li, do you see anything?" Hearing Li Feng's words, Duan Fei's eyes lit up and asked quickly.

Facing Duan Fei's problem, Li Feng shook his head and said, "nothing. Although I can't understand these things, the patterns on them are a little like those murals on the walls of the corridor outside. I think there may be some connection between the two!"

"This thing is called thunder gun. It's a powerful weapon. It's just a disposable item. It's gone when it's used up!"

Just when they were confused, Duan Fei suddenly heard a female voice singing in his mind. Listening to the tone, Duan Fei's eyes lit up and knew it was an "evolutionary tree".

"So you know!" Duan Fei exclaimed and blurted out.

"What's the matter? What do you know?" Hearing Duan Fei's words, Li Feng was stunned and didn't react for a while.

"Well, nothing, nothing!" Realizing that he accidentally shouted out, Duan Fei quickly calmed down his restless mood and asked Lori of the evolutionary tree through his mind: "the gun of thunder, you say this iron bar is what the gun of thunder!"

"Good!" Laurie, the evolutionary tree, paused slightly and said, "this thing is a powerful weapon created by the last earth civilization. Once started, the iron bar will become a thunder in the shape of a spear. It has great power. Even if the S-class monster is attacked by the thunder spear, it will be seriously injured if it does not die!"

"Such a pervert!" Duan Fei exclaimed, and a surprise light welled up in his eyes.

"Nonsense, the scientific and technological level of that civilization is much higher than you humans. It's not surprising that you can build such weapons. Don't you have any nuclear bombs?" Laurie of the evolutionary tree mocked for a moment in a contemptuous tone, and then said:

"Xiao Feifei, you should know Zeus! In ancient Greek mythology, Zeus, the Lord of the gods, was armed with thunder. At that time, you humans were foolish and thought he could really control the thunder, so you regarded him as the true God. In fact, Zeus was just a citizen left over from the last civilization. He had no ability to control the thunder. What he used was just the thunder spear.

However, Zeus's weapon "spear of victory" is genuine, and the "spear of thunder" in your hand is just a replica of "spear of victory", so one can only be used once, and its power will be greatly reduced! "

"Then how can I use the thunder spear!" Listening to Laurie's explanation, Duan Fei couldn't help asking.

"It's simple. If you want to use it, you must first let it recognize the Lord. You just drop your blood, and the thunder spear will automatically detect your genes. After you recognize the Lord, you can use it. However, the thunder spear is a replica, so you can kill level s monsters. Of course, although level s monsters can't kill them, they should be returned below level B It's easy to spike, so don't be too disappointed! " Laurie said slowly.

"Don't be disappointed, don't be disappointed, how can I be disappointed!" Looking at these two ugly iron bars, Duan Fei was full of excitement.

A weapon that can directly kill class B monsters. What a terrible existence.

You know, his strength now is only level E awakener. Even if he meets Level C, he can only run for his life. With this thunder spear, if you encounter powerful monsters in the future, when you can't escape, you can successfully kill monsters and get out of danger by using the thunder spear.

It can be said that with a thunder spear, you will have one more life in the doomsday world full of monsters.

Quietly looking at the two thunder spears in front of him, Duan Fei's eyes flashed with joy. Then he directly bit his middle finger, and a drop of blood slowly dropped on the thunder spear in his hand.
