As an explorer who has passed the assessment, Chen Xi has a certain understanding of most of the mutants active on the surface.

Among them, the sharp-toothed beast, which has the largest number and the fastest reproduction rate on the surface, is naturally the focus of research.

The Sharptooth, a C-Class variant, is a mutation of a small canine with a keen sense of smell and hearing.

As a single mutant, the Sharptooth is not a big threat, and the most feared thing is the Sharptooth tide after the formation scale!

Everywhere you go, lives are in ruins!

Whether it's a mutant or a human, they can't wait to stay away.

Therefore, from the very beginning, Chen Xi did not plan to go head-to-head with the sharptooth beast tide alone.

That's something idiots and Long Aotian would do.

His plan is to use the sharp tooth to make a loud noise and attract the tide of sharp tooth beasts in the abandoned mall to other places, so that the Tomorrow team in the mall can escape!

From the moment he received the distress message, Chen Xi quickly went through the resources and information he could use in his mind.

When he found out that he had an item like [Artillery Battle] in his hand, a plan to "turn the tiger away from the mountain" quickly took shape in his brain.

The sound of the artillery must have been loud enough.

Just set it up somewhere near the mall and light it up, and the sound it makes is enough to attract the tide of sharptooth beasts in the mall.

However, Chen Xi considered another problem:

The brief sound of cannonballs was uncertain enough to attract all the sharptoothed beasts in the mall.

Therefore, he had to find a way to add another insurance on top of the artillery battle.

This is also why Chen Xi asked Wang Tao for an alarm clock!

。。。

The falling snowflakes seem to never stop like this scene of apocalyptic ruin.

Leaving the abandoned building, Chen Xi bent down slightly, cautiously stepped on the white snow, and sneaked towards the direction of the mall step by step.

He didn't stop until he reached the side of the street, which was just over a hundred meters away from the main entrance of the mall.

"The distance is almost there, and the open environment should allow the sound to travel farther..."

Looking around and confirming that there were no other mutants nearby, Chen Xi began to implement his plan:

First, after wiping the snow on a stone pier on the side of the road and laying the artillery battle flat, Chen Xi did not forget to tie a rope to the lead of the artillery battle, so as to achieve the effect of delaying the ignition.

After all, he had to stay away from the area before the artillery was lit.

Otherwise, before he could run far, the tide of sharptooth beasts attracted by the sound of cannons would tear his whole body to shreds.

Chen Xi thinks that he can't sacrifice himself for others.

Saving people is good, but it should be done in a way that ensures your own safety.

If he had to put himself in order to save someone, he would rather not do this kind of fucking fucking stupid thing to open the door to!

After setting up the artillery battle, he took out the alarm clock from his backpack, checked the time with the mechanical watch on his wrist, and then set an alarm clock three minutes later, and then put it on the roof of the abandoned car more than ten meters away from the artillery battle.

On the way here, he experimented with a piece of rope of the same length to see how long it would take to burn it.

The result of the experiment was two minutes.

That is, two minutes after the rope is lit, the cannon is ignited, which makes a loud noise.

And after the sound of the cannonball, the time it took for the Sharptooth Tide to arrive here was about half a minute to a minute.

Therefore, the alarm clock must sound within a short period of time after the arrival of the Sharptooth Tide!

Only in this way can the team of tomorrow in the mall get more time to escape.

Of course, without experimentation, the timing cannot be so accurate.

However, as long as he can attract the Sharptooth tide and don't return to the mall so quickly, his plan will be more than half successful!

After taking out the lighter and lighting the extended rope, Chen Xi turned around and ran without hesitation.

Taking this opportunity, he also did not forget to experiment with the new skills he had just acquired:

"Sprint!"

With a silent thought in his heart, Chen Xi, who was running on the snow, felt that his whole person suddenly became a little lighter, and the pace under his feet was also a little faster.

The effect of the skill is not very significant. However, you can still feel the speed bonus that comes with using skills.

If his speed was comparable to that of a municipal sprinter before using the [Sprint] skill, then after using the [Sprint] skill, his speed has reached the level of a provincial sprinter!

After running out of the street with a puff of smoke, Chen Xi, who had lost his skill bonus, slowed down and looked at the time on the mechanical watch, while cautiously half-bending and touching towards the back door of the abandoned shopping mall.

The Abandoned Mall is the largest and safest building in the vicinity of the waterworks, and it is also the base where Tomorrow's team stops for a short time every time they go to the waterworks.

Therefore, Chen Xi is quite familiar with the terrain of the entire abandoned shopping mall.

That's why he set up the cannon on the street in front of the main entrance of the abandoned mall.

In this way, when the tide of sharptooth beasts is attracted by the sound of cannonballs, the best escape route for Tomorrow's team is the back door of the abandoned mall!

Two minutes, fleeting.

As soon as he came to a dilapidated house dozens of meters away from the back door of the mall, Chen Xi estimated the time, and then looked down at the mechanical watch on his wrist again:

"Almost..."

In a whisper, a crackling cannon battle suddenly sounded, and it immediately spread throughout the entire area!

The sound of the artillery was fierce and short.

Looking at the abandoned shopping mall not far away through the window of the house, Chen Xi couldn't help but look like a deep starry sky, shining brightly:

"Next, it's up to you..."

。。。

The sudden sound of artillery fire interrupted the argument of Tomorrow's team.

"What's that sound?!"

"What's going on? Someone is shooting? ”

Before the Tomorrow team and the others could react, the entire abandoned mall resounded one after another with piercing howls.

The sharptoothed beasts, which were extremely sensitive to sound, did not hesitate at all, no matter what layer they were on, and immediately rushed in the direction of the sound source.

Some even jumped out of the floor-to-ceiling windows on the second floor, just to be able to get to the sound faster.

Based on the limited intelligence and animal instincts of the sharptooth beast, it must be the prey that can be hunted and killed if it makes such a big movement!

Thundered...

The Tomorrow Squad and the others who were hiding in the shop could clearly feel the slight vibration transmitted from the ground to the buttocks.

It was the sound of the tide of sharptooth beasts running together!

Several explorers hiding behind the shelves involuntarily shrank their feet, for fear of being spotted by the sharptooth beasts running by.

After all, it was Lu Dachuan who was more experienced and the first to realize that this was an extremely rare opportunity.

I saw him straighten his waist all of a sudden, raise the iron long knife in his hand, and reminded in a deep voice:

"Brothers, here's your chance!"
