Everyone mourned the deceased, and while they were resting and bandaging their wounds, Qin Fen thought about it and took out the key he had dropped after killing the two elite monsters earlier.

He took out the key that emitted a faint silver glow and smiled:

"What do you guess this key can do?"

"Silver Key?!" The well-informed Miss Yinzi couldn't help but be shocked, and then said with a smile, "It seems that you are lucky." ”

Qin Fen nodded and smiled:

"With a small probability, we killed two elite acid toads, only dropped one key, and then this thing came out."

After the key was opened, Qin Fen was suddenly a little dumbfounded: because there was nothing in it! That's a lot of survival points! It was transferred directly to the account of his watch. And it's with that kind of beating number bonus. Watching the numbers that represent wealth beat like crazy and growing, I don't know when it will stop, I have to say that such a setting is quite pleasing to the eye and full of expectations.

Even Ai Jia'er, who didn't have much concept of the silver key, widened her eyes in surprise, because in just this short moment, Qin Fen had already gained more than three thousand survival points! For a cute girl who has passed the novice task with the lowest level of completion and only has a pitiful 1,000-point base reward at hand, this method is undoubtedly more direct and shocking.

Thirty seconds later, the speed at which the survival points were rising and beating finally slowed down, and in the end, Qin Fen saw that he had increased his survival points by more than 7,000 points, which was quite a good reward.

"Wow, we've earned it!" Miss Silver was excited and pink, shouting. You must know that the sum of all the previous benefits of everyone was only more than 8,000 survival points, and now a key has opened double the benefits, which can be imagined how pleasing it is.

Three minutes later, everyone who had already rested properly walked down, and Qin Fen once again summoned a vampire bat to explore the way, although each summon required a lot of commissions, but this was not the time to care about this. Caution can make a ship of ten thousand years.

Soon, several people came to the back of the boulder, the Titan was looking intently at the Zerg brood under construction in front of him, and the other soldiers sat in the shadow of the boulder in twos and threes, nervously wiping their guns, obviously knowing that a fierce battle was coming.

It is worth mentioning that the lieutenant colonel and Commander Taylor who stayed behind were also brought over by Miss Silver on the road, after all, there was a big battle next, and at this time, any little force could affect the final situation, and there was no room for sloppiness.

"I think it's better for us to get out of here......" The lieutenant colonel's face was pale, still making his last struggle.

Before Qin Fen could speak, Commander Taylor next to him had already said calmly:

"Lieutenant Colonel Bismarck, remember, you are a soldier. Maybe the years have eroded your dreams, and the wine has hollowed out your body, but please at least remember the glory of the past...... We need role models and heroes, not cowardly soft-boggards. ”

As a result of these words, the lieutenant colonel's face turned red and he closed his mouth in a daze.

At this time, Qin Fen suddenly received a prompt from the master:

"The current task has changed. Content: Kill the Brainworm of the Blacktooth Tribe within six hours. ”

The Titan walked over and said:

"Did you get a prompt?"

Qin Fen nodded and said, "Well, it's no wonder it's a hidden mission, and we are specially allowed to recruit companions and leave survivors...... The Zerg's brain worm is not so easy to kill. ”

"Luckily, this group was greatly weakened in the battle, and the fleeing brainworms invaded this place with the remnants of their defeated soldiers, intending to build this place into another base. But it's only been twenty-four hours since they invaded the whiskey base, and it's impossible for them to fully recover their strength...... That's where we got the job done! ”

"It is worth mentioning that most of the Zerg are creatures that live in the sun, and the darkness will have a great impact on their movements. The Terran soldier's combat suit is equipped with a standard infrared detector, which is part of the advantage. Moreover, the ground here is mostly volcanic rock and condensed limestone, which can effectively avoid the attack of the Zerg from underground. ”

The Titan smiled and said:

"Brother Qin is really talented, and he can analyze the current situation thoroughly as soon as he arrives...... I've just asked Shoko to scout the brood's defenses, and found that attacking the brood from here is the weakest. The tentative plan was to attack in a harassing manner, each lasting only a few minutes, to lure the Zerg out in batches. While consuming the opponent's vital strength, and then making the Black Tooth tribe exhausted and completely unable to understand the direction of our main attack, and finally launching a general attack from here, the task can naturally be completed. ”

Looking at the map in front of him, Qin Fen thought seriously for a while, and finally looked at the Titan, but he stopped talking, and the Titan smiled and said:

"Of course, this is just a preliminary plan we have made, and it is inevitable that there will be omissions, and it is better to talk about problems now than to have a gap after entering the battle."

Qin Fen nodded and said seriously:

"The current Black Tooth tribe is in ruins, most of the soldiers are killed and wounded, and when they first arrive, the main force should be placed on rebuilding the base, so there is no doubt about the emptiness of the defense, if the guess is correct, the troops they hatch for the first time should be the lowest level of mining troops with the lowest consumption, as for the high-level troops such as firethrowers, even if there are numbers, there will never be much. But don't forget, the brainworm is no less intelligent than us, and it even knows how to send telegrams to lure humans to death! So, will it allow us to safely consume and eat away at its vital power? ”

The Titan frowned and said:

"You're saying that the brainworm might take this opportunity to produce high-level troops against us?"

"It's not a possibility, it's a certainty." Qin Fen nodded, "At least it has already started to produce the medium and long-range troops of the acid toad, otherwise with the movement speed of the acid toad, it will definitely be the cannon fodder left behind when it retreats." ”

"It's understandable – it's a bit like Red Alert in a strategy game. The Black Tooth tribe occupied this place, expanded its base, and began to develop, but in the early stage of development, it was almost unable to manufacture 'ultimate weapons', and could only focus on gathering resources to accelerate development. The biggest possibility is to produce low-level troops to assist some small number of medium and long-range troops, and suppress the sea of worm tactics. It is likely to be struggling now, unwilling to slow down the development speed to produce more advanced troops than it can bear, after all, there is a big enemy not far away, so it will send troops to snipe us constantly on the road. ”

The Titan was silent for a moment and said, "So, we still have to fight quickly?" ”

Qin Fen nodded and said:

"There is a cloud in the art of war: one blow, then decline, and three exhaustion. Don't forget, we don't have a lot of manpower, and we can't afford to wear guerrilla for a long time! ”

"Okay, prepare for three minutes, let's find the weakest link and attack directly!"

"But if you have a certain number of low-level troops, it will be quite a headache."

"Brother Qin, don't worry!" The titan laughed: "No diamonds, no porcelain work!" If it's just a low-level class, I can definitely block it! ”

……

Busy worker bees, misshapen, massive scarlet organ buildings, floors with a carpet of viscous organic matter...... All of this is no different from the brood base that everyone sees in the wild, the only difference is that there are clear red stripes on the surface of both the buildings and the creatures.

Regardless of what the brainworm thought, three minutes later, the well-prepared adventurers began to attack on time.

The attack was to the northwest of the brood, where only a tongue battery (similar to a machine-gun bunker) stood alone, and the defense was neither high nor low. The structure had a strange shape, as if a pig's nose had been cut off and erected on the ground, and it was brown from top to bottom, with several thick barbed tentacles growing out of the ground below, binding the main body of the fort. The turret also has vine-like vains coiled on its surface, and although it does not move, its attack range is quite long, and when it finds a target, it spits out tongue stabs from the turret, and can deal continuous and rapid blows to invading enemies.

"Well, this tongue thorn fort must have just been built, and there are even nutrient vesicles at the roots that have not yet fallen off."

“good。” Qin Fen snapped his fingers to attract everyone's attention, and at this time he had already begun to naturally show the temperament of a team leader: "Do you see that tongue thorn battery next to the rift valley a kilometer away?" We'll attack from there. The Titans and I deal with the Zerg sappers, and if there is an acid toad attacking, we will leave it to Glasses Niang and Zhang Ying to take care of it, and make sure to destroy them before they cause devastating damage! ”

Titans are also Taoists:

"You assist me in my defense, and if necessary, unleash your "Supreme Roar" swarm skill to kill and control the swarm, as a means of forgiving the team in times of crisis. The other soldiers followed behind us, and the main goal was to destroy the tongue stab battery first! …… Fight for our lives! ”
