downstairs.

Lin Jiao, Xu Bin, Chen Tao, and Chen Hao also suddenly felt the walls around them shaking.

The power is really amazing.

They knew what was going on and stopped immediately.

Lin Jiao couldn't help but exclaim in surprise: "Boss, this time your actions are too fast."

Xu Bin nodded in surprise. Last time, the boss waited for a long time before taking action.

Several people immediately turned around and went upstairs to check the situation.

…

Lu Feng appeared in the real apartment, and the next moment, he received a prompt:

[Congratulations on killing a mutant beast-killing dog and gaining 100 experience points!]

The power of two gas cylinders was indeed enough.

The experience increased by 100 and became LV4: 310/800.

He immediately looked towards the game world. The shop had been blown to pieces, and so was the mutant beast's torn body. However, not much blood was flowing out because the wounds were scorched by the high temperature.

The flames once again triggered the department store's waterproofing system, and the sprayed water soaked the shop, mixed with black ash, making the whole shop look a bit muddy.

Lu Feng came in and immediately used a steel knife to dig open the mutant beast's head, and indeed dug out something from inside.

[This is the crystal source of the mutant beast-killing dog. It is very valuable and can be used as currency or energy. Its crystal source value is: 12!]

The energy value of this crystal source is actually 1.5 less than the previous one.

It seems that the crystal source energy values ​​of the same monster are not the same, which may also be related to the individual strength of the monster.

Then, Lu Feng was suddenly attracted by a sign wrapped in white light floating next to the monster's corpse.

That sign was somewhat similar to the previous Qingfeng Tea Life Skills sign, and it looked very abrupt floating there.

He realized what it was, because cards like these in gaming were special items with different functions.

Moreover, this seems to have exploded from killing mutant beasts.

In the game, killing some monsters and bosses can indeed drop these special item cards.

While Lu Feng was stunned, Lin Jiao and the other three arrived outside the shop and walked in.

Looking at the corpses of the mutant beasts inside, I felt shocked.

This was a very terrifying monster for them, and the second one had already been dealt with.

But Lu Feng looked at Lin Jiao and the other three in surprise. It seemed that they could not see the sign wrapped in white light, otherwise they would definitely not have no reaction.

He quickly took advantage of the four people's inattention and grabbed the sign with a stealthy move, using the game's exploration function:

[This is a special backpack grid exchange card. After using it, you can exchange it for one grid of backpack space! ]
