"Binocular infrared thermal imaging telescope?"

Su Heng stared at the reward just issued by the system and checked its entry attributes.

[Binocular infrared thermal imaging telescope]

[Quality: Superior]

[Grade: Advanced]

[Function: The maximum survey range is 2km (adjustable), and thermal images can be effectively observed within the range,]

[Evaluation: It can make you look like a falcon and accurately lock on the target! ]

"nice one!"

Su Heng was secretly amazed. Now, when he goes out for activities, he can observe the situation in the distance without taking drugs.

[Current Doomsday Honor Remaining: 1410 points]

"There's only 590 points left to upgrade the food processor."

"I have to get the raw materials quickly and complete the second task."

It was noon after setting up the farm shed. Su Heng took Lolo back to the underground shelter.

He took out the Doomsday Observatory and observed it, except that it could be used as a fixed telescope, Su Heng did not see the third disaster.

"It seems that there will be no disaster for a while."

Su Heng first cleaned up the stove and turned off the heating pipes between the stove and the kang.

After the snowstorm is over, there is no need for heating, but traditional stoves can be used as stoves.

Taking advantage of the lunch time, Su Heng took out the resource map.

[Players please select a resource]

"Potassium nitrate!"

Su Heng chose Road without hesitation.

[Displaying for you, please wait...]

[The ore resource coordinates of the current living area [potassium nitrate] have been displayed for you]

The system prompt disappeared, and the resource map in hand turned into a 3D map of the 13th survival area.

The map is covered with large and small solid circles, marking the location coordinates of potassium nitrate.

[Ps: Crimson coordinates may have high-star alien beasts gathering, please proceed with caution! 】

The lighter the color of the coordinates, the smaller the circle, which means that the resources are poor, but the risk factor is not high.

The redder the color of the coordinates and the bigger the circle, the richer the resources and the more dangerous it is.

Su Heng carefully checked the 3D map and first found the location of "Yuntongtuo" where he was.

"The nearest resource-rich area is in the Purple Bamboo Forest?"

Su Heng saw that the nearest red coordinate was on Yan Wan's side.

"The road over there is not easy to walk, and maybe you will encounter Yan Wan, an enemy."

Su Heng shook his head and continued to check the map.

There are two small mines near Yuntongtuo, light in color and small in circles, located 2.4km north and 3.1km southeast respectively.

"It's no wonder that I didn't use the Doomsday Observatory to find the nearby mines. It turned out that the mines closest to me were 2km away."

Su Heng marked the two small mines as the No. 1 vein and the No. 2 vein.

"The No. 1 mine is the closest to me, and the road is not easy to walk."

"Although the No. 2 mine is a little farther, the road is smooth."

"If it goes well, both mines can be explored in one afternoon."

"In the future, just send Xiao Hei to mine."

Su Heng made a detailed plan of action for the afternoon.

After finishing lunch, Su Heng put on his equipment and prepared to leave.

"Xiao Hei won't take him there. It's not easy to walk on the potholes on the road, so just stay at the shelter."

"Ow~"

When Luo Luo saw Su Heng wearing black-scaled chain mail, with a crossbow on his back, and a dagger on his back, he called out to him.

"I'm not going out to play."

"If you want to go out, you must wear black scale armor."

"Also, if you roll into the mud pit again, I will definitely beat you up."

Su Heng reprimanded Luo Luo severely.

"Meow~" Luo Luo let out a very aggrieved cry.

It seemed to know that Su Heng was angry, and sat on the ground obediently, expressing that he knew what he had done, and was willing to wear black scale armor.

"The No. 1 and No. 2 ore veins are all outside the detection range of the sentry radar. It is better to be more stable."

When Su Heng went out, he put on his gas mask again.

He had two daggers in his waist, enough crossbow arrows on his back, and 5 disaster snow grenades, and he was fully armed.

Su Heng attaches great importance to this outing, no less than the airdrop battle.

"Set off!"

Su Heng took Lolo carefully towards the position of the No. 1 ore vein.

"The road is a bit difficult to walk!"

According to the route marking on the mine map, it took more than 50 minutes for Su Heng to reach his destination.

"Why does it stink?"

Even though Su Heng was wearing a gas mask, he could still smell the bad smell.

The terrain here is relatively low. Below the water level, there are clods mixed with rocks nearby, and there are hard mountain walls not far away.

The ore vein map is just a rough guide for Su Heng, and it won't go down to the exact distance of m. The exact location of the ore vein has to be explored by Su Heng himself.

"Where will it be?"

When Su Heng was at a loss, Luo Luo suddenly called out to the mountain wall on the left.

"Ow~"

It seemed to know what Su Heng was looking for.

"You mean, they are inside the mountain wall?"

"Meow~"

Luo Luo nodded towards Su Heng.

It seems that Luoluo has a natural discernment of mineral veins.

"Okay, I'll trust you once."

Such a thick mountain wall, if you dig with a shovel or a hoe, it will be time-consuming and labor-intensive.

Su Heng decided to use the simplest method.

Blast!

Su Heng took out a snow disaster grenade and placed it next to the mountain wall.

"I'll pull the fuse in a while, it's this iron ring, you just follow me and don't stay where you are, understand?"

"Meow~"

"Just understand."

After pulling the fuse, one person and one tiger head ran away without looking back.

A few seconds later, there was a loud noise.

boom!

Su Heng stopped and turned around to check.

"This... it's not deep enough!"

Only a hole the size of an electric car tire was blown out of the hard mountain wall, and Su Heng couldn't see the mineral resources inside.

"It has to be fried again."

Su Heng then put in another disaster snow grenade.

boom!

boom!

rumbling

With three grenades in a row, the mountain wall was completely blown apart by Su Heng's simple and crude method.

In front of him is the size of a door frame, with an opening of about 2 meters to the outside.

"It's really tough!"

After the opening was blown up, the coordinates of this ore vein disappeared from the 3D map, indicating that it had been mined.

Su Heng leaned down to see how much cargo was in this mine.

His psychological expectations are not high, as long as he can get dozens of kilograms of saltpeter. After all, the color of the No. 1 ore vein is very light, and it has been told from the map that there are not many resources here.

But...that's too little!

What the **** is this fingernail-sized saltpeter!

The mine is not the kind of irregular saltpeter bigger than a plate, not even a palm-sized saltpeter.

Some are just mixed with strange soil, only the size of a fingernail, with white crystals with vitreous luster.

Su Heng picked up a piece and checked the entry attributes.

[nitre]

[Quality: Superior]

[Grade: Advanced]

[Crystalline saltpeter can be used to make colorful/pastel/gunpowder]

[Evaluation: Explosion is a man's romance! ]

"Huh? This soil also has entries?"

Su Heng grabbed a handful of soil.

[nitre]

[Quality: Lowest]

[Grade: Normal]

[Soil containing nitrates such as potassium, sodium, calcium, magnesium, etc., can be used to make fertilizer/gunpowder]

[Evaluation: It is formed from organic matter with N element such as feces and urine through complex chemical action, please be careful! ]

"I lost it!"

Su Heng hurriedly threw away a handful of nitrates in his hand, took out alcohol and poured it on his hands to disinfect.

When all the alcohol evaporated and there was no sign of infection on his hands, Su Heng let out a long sigh of relief.

"Can this also be called a mine?"

"It should be some mutant beast that often comes here to go to the toilet!"
