"It's coming pretty fast."

Listening to the movement getting closer and closer to the entrance of the cave, Lin Cheng, who was hiding behind a broken wall, sneered, and counted down to ten counts according to the rhythm of the footsteps in his heart, and with the last "zero" blurted out, Lin Cheng suddenly stood up, and the two submachine guns were aimed at the few giant rats that had just rushed out of the cave and pulled the trigger angrily!

"Sudden ——!!!"

"Sudden ——!!!"

"Twitter!!"

"Squeak-"

The C-type submachine gun produced by the capsule system is not loud alone, but the terrifying lethality of each bullet that can take the life of a mutant giant rat silently tells everyone the manic power contained in its small shape, those giant rats that have just rushed out of the hole are swept into meat sauce by the C-type submachine gun one by one before they even see it, and the piercing screams before dying echo throughout the underground base, rendering the atmosphere here in an instant rendering a deadly blood!

Ten minutes later, as the first batch of giant rats that rushed out of the cave were swept into a sieve by submachine guns, Lin Cheng, who had a lot of momentum, put away his two guns with a "click", and gasped slightly.

Seeing that no giant rat dared to rush out of the hole for the time being, he snorted lightly, exhaled out the system menu and checked the energy value points, and the corners of his mouth suddenly couldn't help twitching!

Existing energy value: 8178286 points.

Total energy value: 9312934 points.

That's right, after the frantic strafing he just now, his total energy value has increased by more than 9,000 points, and based on the average energy value that a mutated giant rat can provide him with 200 points, he probably killed forty to fifty giant rats with a submachine gun just now.

But the problem is that aside from the 100,000 energy points consumed by exchanging two C-type submachine guns, just the ten boxes of bullets consumed just now are already worth 20,000 energy points, and when converted, in just ten minutes or so, not only did he not earn a little energy value, but he also lost more than 10,000!

This is why he didn't choose to use the C-type submachine gun in the previous big melee, this short ten minutes of battle made him lose more than 10,000 energy points, if he chose to fight with a submachine gun at that time, I'm afraid he would lose his pants after a big battle!

Although the energy value is not the most important thing compared to life, Lin Cheng was not in a desperate situation after all, he had too many hole cards to deal with the situation at that time, but he didn't expect the sudden appearance of the mutant giant rat leader to disrupt his plan, and he has been thinking about the exchange of B-type strengthening potions, after realizing that he had to save money, he was trying to save energy value in the subsequent battles for no reason, At this time, it is simply impossible for him to take out more than ten or two hundred thousand energy points to fight a battle with little suspense in the ending.

Sighing very distressedly, Lin Cheng raised the submachine gun in his hands and glanced at it, and finally gritted his teeth and put them into the storage capsule, although the weapons produced by these capsule systems are extremely powerful, but they are all money-eating machines, and he is really reluctant to take them out and squander them until he has to.

Fortunately, those giant rats were already frightened under the wild sweep he just now, and they no longer dared to probe out of the cave easily, after all, the bones of the 'seniors' were still piled up at the entrance of the cave, because the death speed of those giant rats who rushed out of the cave was too fast, and the corpses of these giant rats were almost covered by the accumulation of the cave entrance, and the river of blood that converged floated a strong smell of blood, rendering the atmosphere of the entire underground base with a layer of solemn meaning!

Frowning and dissipating the smell of blood wafting to his nose, Lin Cheng raised his feet and took a few steps forward, seeing that there were still no giant rats rushing out of the cave, so he reached into his pocket and took out a brand-new C-type grenade!

"If you can understand me, get your leader out at once! Otherwise, you're going to face more than just a little scene like the one you just faced, you know?! ”

Standing at the entrance of the cave, Lin Cheng pulled the grenade ring off with a "poof", and shouted loudly to the giant rat in the cave while raising his hand to throw it!

That's right, this is the plan that Lin Cheng conceived after seeing this hole, as mentioned before, these giant rats have evolved self-awareness, and after having self-awareness, whether they want to or not, the idea of cherishing life will be firmly rooted in the hearts of each of their 'people', the previous indiscriminate strafing is just a means for him to play, and the ultimate goal is actually to force the giant rat leader to appear!

Although he didn't know if they could understand human speech, Lin Cheng was willing to gamble that these giant rats could understand human speech, and that the mutant giant rat leader who was put on the shelf by his own words was forced to show up to face him!

Gusts of cold wind whistled through the passage behind Lin Cheng, and the sound of dripping water came from all around from time to time, two minutes passed, and Lin Cheng had even walked to the entrance of the cave, but there was still no response from the cave.

"Heh, what kind of leader should you be so afraid of death? Go home and raise your pigs! ”

In the end, Lin Cheng, who still didn't get any response, finally lost his patience, and after a few sarcastic words, he threw the grenade in his hand violently and threw it towards the entrance of the black hole!

"Whoosh-"

"Knock, knock......"

As the grenade flew into the cave, Lin Cheng heard the sound of the grenade rolling on the ground, which lasted for several seconds before finally stopping somewhere deep inside the cave.

"These guys...... It can't be a runaway, right? ”

Seeing that he was so frightened, but the leader of the giant rat still didn't mean to show up, Lin Cheng couldn't help but muttered in his heart, could it be that the deterrent method he had just used was too strong, and he directly scared these giant rats and ran away?

But he clearly remembered very clearly, at that time, just because he killed a few giant rats that wanted to attack him, the giant rats hiding in various parts of the underground base seemed to be crazy, and killed them one by one, this strong sense of revenge made him extremely impressed at that time, and it was precisely because of this that he came up today and opened full fire, in order to completely anger the mutant giant rat leader and let it appear!

Just thinking about whether he had made a mistake in any link, Lin Cheng suddenly heard a sound of breaking the air coming from the cave, and hurriedly looked up, and saw that the C-type grenade he had just thrown in was flying straight towards his face at this time, and he saw that it was about to hit his nose in the next second!

Thinking of the terrifying power of this C-type grenade, Lin Cheng's heart suddenly became furious, and he flashed to the side as quickly as possible, and then he heard an earth-shattering bombardment sound coming from behind him!
