Global Cataclysm: Start building a dungeon

The walls of Jiangcheng can already be clearly seen!

The distance is less than one kilometer!

At this time, the height of the avalanche had reached a terrifying 14 meters!

next moment.

Boom! ! !

A loud bang.

It was like a bolt from the blue!

The 14-meter-high avalanche directly hit the wall of Jiangcheng!

In an instant, the splashed snowflakes flew directly to a height of nearly [-] meters!

Then with the blizzard, it fell violently!

At this moment, the avalanche from behind surged up again!

Rumbling--

Another bang!

This time.

The position where the avalanche hit the wall almost reached the apex of the wall!

Ye Liangren clicked the pause button at this moment!

Then pull in the viewing angle of the monitoring screen.

See, this time the avalanche is only five centimeters away from the wall! ! !

Ye Liangren's eyes changed slightly!

Then monitor the playback of the picture again.

The avalanche was blocked and gradually stopped.

Then, it began to flow continuously towards lower geographical locations!

Ye Liangren turned his head, feeling a little complicated.

The moment he presses pause.

At the moment he saw the avalanche just five centimeters into the wall.

He was afraid for a while!

Once the avalanche goes over the wall.

The avalanches in the back can completely follow the trajectory and pass them all!

At that time, Xue Beng will be able to jump over the wall and fall directly to Jiangcheng.

Moreover, it fell directly from a height of 15 meters!

Maybe, it can't threaten the residents in the center of Jiangcheng.

However, the residents living on the edge will undoubtedly be completely submerged by the snow falling from the sky in an instant!

Fortunately, the building was just submerged by snow, and maybe it could be saved.

If you are unlucky, the house will be crushed directly, and it will be completely cold!

And all of this, he didn't even know about it!

You know, there are not a few residents living on the edge! ! !

He almost lost a large part of the residents!

Although, this worst case did not happen, but he had to take precautions!

"System! Why didn't you remind me of this avalanche?!"

Ye Liangren asked immediately.

The next moment, a virtual screen popped up.

"Ding!After testing, this avalanche cannot cross the T2-level steel wall. Therefore, there is no danger in Jiangcheng, so there is no warning! 』

See the information on the virtual screen.

Ye Liangren couldn't help frowning!

Some headaches.

"If you can't cross it, you won't be reminded. Will you only be reminded if you can cross it?"

"According to the speed of the avalanche, it is really possible to cross it. By the time you remind me, it will be too late!"

"Sure enough! I still can't wait for the system's passive reminder. Once the reminder time is one step late, not to mention that I don't have time to respond, even if I have! If I need to upgrade the building at that time, but I don't have enough materials, I will lose a lot of it." residents!"

"So, we must make first-hand preparations in advance!"

"Especially, it's only been two days since the big cold snap!"

"There have been avalanches of this magnitude in two days. As time goes on, there must be a high chance of a bigger avalanche, an avalanche that can easily cross the wall!"

Thinking of this, Ye Liangren nodded!

Time is running out, let alone take it lightly!

"If you want to resist the avalanche, or, start directly from the source!"

"Building countless snow plows... No, the snow plows are meaningless, the efficiency is too low!"

"Directly build countless sprinklers to sprinkle water within a radius of 24 miles outside Jiangcheng [-] hours a day, so as to reduce the amount of snow accumulated within [-] miles as much as possible."

"At that time, when the avalanche rushes in, the follow-up will be weak, so it will be impossible to hit the wall again!"

"Or, just upgrade the wall directly!"

"Raise the height of the wall again!"

"No matter how big the avalanche is, no matter how fierce it is, it can't be overcome!"

"Both methods can be solved."

"Then, it depends on the material, which one is used less!"

With this in mind.

Ye Liangren instantly looked down at the angle of view, and had accumulated information for more than two days.

"Ding!You successfully collected materials: 400 kg of pure iron!Reward: Survival Points +240. 』

"Remaining survival points: 91150. 』

……

"Ding!You successfully collected supplies: 400 kg of titanium alloy!Reward: Survival Points +330. 』

"Remaining survival points: 106650. 』

……

"Ding!You successfully collected materials: 400 kg of aluminum alloy!Reward: Survival Points +400. 』

"Remaining survival points: 119720. 』

……

"Ding!You successfully collected supplies: 400 kg of copper!Reward: Survival Points +800. 』

"Your current remaining metal supplies:

Pure iron: 43450 kg!

Titanium alloy: 23650 kg!

Aluminum alloy: 18300 kg!

Copper: 7200 kg!

Sand and gravel: 0 kg!

Energy stones: 0! 』

"Remaining survival points: 125420. 』

Look at the material data.

Ye Liangren frowned again.

"Except for sand and gravel, everything else is quite sufficient!"

"But! When building a T2-level steel wall, the most materials needed are sand and stone!"

Ye Liangren shook his head violently.

"Upgrade first!"

"Maybe after the upgrade, when building a T3-level wall, you don't need sand and stones!"

Ye Liangren spoke immediately.

"System, upgrade the super research base!"

"Ding!Spend 4000 survival points to upgrade the super research base successfully! 』

"Remaining survival points: 121420. 』

Ye Liangren looked at the research base instantly.

"Super Research Base"

"Level: 6. 』

"Upgradeable! 』

"Direction: Level 7! 』

"Upgrade direction: scientific research level (8000). 』

"Currently available weapon series:..."

"Currently available defensive equipment series:..."

Chapter 225 Methods

Ye Liangren looked at the data again.

『Note: Each T3 grade alloy wall is 30 meters long, 20 meters wide, and 100 meters thick!Surrounding the entire Jiangcheng requires: 25 yuan!2 per side! T3-level steel walls are upgraded to T[-]-level alloy walls, and the materials are halved! 』

『Note: The working efficiency of T3-level large-scale sprinkler is four times that of T2-level large-scale sprinkler, and the upgrade materials are halved!For each sprinkler, the range of the water cannon can reach one kilometer! 』

see this info.

Ye Liangren couldn't help frowning!

"Even if it is upgraded, each piece of the T3-level alloy wall needs 250 kilograms of sand and gravel. Even if the upgrade materials are halved, each piece still needs [-] kilograms."

"Although after the upgrade, the width of each T3-grade alloy wall is five times that of T2-grade, and one piece can support five pieces, but... I don't even have a kilogram of sand and stones now."

"It's impossible for the residents of Jiangcheng to collect desperately in the current snowstorm. Even if they take the initiative to collect, the efficiency of collecting frozen sand and stones in this kind of weather is extremely low, and I don't have the time at all. Wait slowly!"

"As for the T3 large sprinkler, although the efficiency has also quadrupled, the range of the water cannon has reached one kilometer!"

"However, I need to cover at least [-] kilometers outside Jiangcheng! Even if the power of the sprinkler is fully turned on, a sprinkler can at most ensure that the snow within six kilometers can melt."
