Five days later, in the early morning, Hu Xiaodao said goodbye to everyone from the ship, and still flew to the place where he returned yesterday in a small helicopter.

This time, Hu Xiaodao brought enough equipment, a multi-functional saber of Swiss origin, a folding sapper shovel, a strong flashlight and eight batteries, emergency lights, several light sticks, tents, sleeping bags, head-mounted miner's lamps and two batteries, a compass, mosquito repellent water, a water bottle, a 30-meter-long paratrooper rope, a GPS, a small first-aid kit and antidote, and a five-day ration for individual soldiers. Of course, the most important ones are lighters and moisture-proof matches.

As for wearing, Hu Xiaodao did not wear a camouflage uniform, but continued to change into a jacket and pants, the underground was humid, and the camouflage uniform did not have a warm effect, so it was not as good as the assault suit.

Since he didn't climb the mountain, just an expedition, Hu Xiaodao began to prepare to choose net shoes, and later thought that it would be better to wear infantry boots.

As for the backpack, Hu Xiaodao did not hesitate to choose a 60-liter hiking backpack of a certain brand, which includes shoulder straps, chest straps, belts, shoulder stress belts, bottom force belts, support devices, ventilation devices and adjustment devices.

A well-performing backpack with a backpack system designed not only for ventilation, but also for gravity transfer, weight capacity and comfort.

As for weapons, Hu Xiaodao does not consider hot weapons, because the environment may not be as handy as cold weapons, and this expedition is estimated to be without any danger, just to untie a knot in Hu Xiaodao's heart, let me not consider firearms.

The Hu knife is equipped with a sheath-type mold Ontario mountain knife, with a wide blade, and serrated teeth on the back of the knife, which is a very reassuring expedition helper.

Before leaving, the comrades-in-arms repeatedly emphasized that they could not just go back, and said that if they found that the Hu Xiaodao on the GPS had been in one place for more than 12 hours, they would set off to rescue them.

After getting off the helicopter, Hu Xiaodao and the pilot waved their hands to express their gratitude, and then embarked on a solo expedition again.

Unlike last time, this time Hu Xiaodao brought enough equipment, and his plan was to spend four days to explore this mine clearly, and the remaining day to return, there should be no big problem.

After entering the cave, Hu Xiaodao didn't need to hold torches in both hands, and it was much faster to climb down the railroad tracks, but after climbing for a few minutes, Hu Xiaodao turned on the head-mounted miner's lamp, and by the way, he also turned on the live broadcaster.

"It's darker than I thought it would be, and you can see that I'm still on the tracks of the mine where I last found the body, and now I'm just halfway up, wait until I go down!"

After a brief introduction to the situation, Hu Xiaodao stopped talking and climbed down step by step.

The speed of using both hands and feet is fast, and after only about ten minutes, Hu Xiaodao is already standing on solid ground.

"I'm on the ground now, it's the same as the last time I came, the difference is that I'm armed to the teeth now, and I've got five days to finally take a good look here!"

After this end, in addition to the corresponding rewards, the system also allowed Hu Xiaodao to reasonably arrange time to recover his physical fitness, after all, every time he survives in the wild, all kinds of data of the human body will decline, and there is a recovery period of about ten days.

But Hu Xiaodao didn't pay attention to the system, the reason is that Hu Xiaodao has always had food, and he keeps working, and there is no problem with his physical fitness, anyway, his longest time is two or three years later, so it is better to spend more time exploring the world and doing what he likes.

This head-mounted searchlight on the head of Hu Xiaodao is an 18650 lithium battery technology, which can illuminate continuously for more than 65 hours, and the waterproof performance is quite good, and it can be undisturbed in deep water at a depth of 20 meters.

This time the original plan was five days, and it was reasonable to bring one battery to be enough, but Hu Xiaodao still brought two spare pieces for the sake of insurance, anyway, the area was not large, and after bringing the necessary things, he finally considered individual rations.

According to Hu Xiaodao's understanding, wild exploration, food - for those of them who have the ability to survive and are tough, the kind that need to be considered.

On the contrary, such as tinder or first aid kits, antidotes, etc., can really enter the eyes of these veterans who have survived on the battlefield.

Not to mention that there are countless rats underground, even on the Siberian ice field, as long as Hu Xiaodao has enough clothes and fire, he will not starve to death.

So food is really not the most important thing for people of their level.

The first element of survival is fire. With fire, anything is easy to do.

Even the system's wilderness survival manual clearly states that fire is more important than water in the desert.

What's in the backpack is just an aid.

Follow the road last time, although the light source is sufficient this time, but Hu Xiaodao, who is used to living a hard life, still adjusts the light from high to low to save electricity, anyway, it can be seen, there is no need to waste it.

Not long after, Hu Xiaodao came to the place where the body was last found. The two bodies were still lying there quietly.

Hu Xiaodao bowed to the corpse, after all, the successful construction of his treehouse had a lot to do with these two people.

After thinking about it, Hu Xiaodao still unloaded the backpack, took out the folding sapper shovel from his waist and began to dig a pit.

It didn't take a few digs to appear here, but Hu Xiaodao is not particular about it, and buried in the mineral salt can at least keep the body from rotting, according to the traditional concept, they are considered to be people with great creation.

The first body was close to the door, and after Hu Xiaodao dug the pit, he dragged him over and put it in the pit, and wanted to continue to drag the second person to bury the two together, but Hu Xiaodao thought that the two were not a couple, and it was not appropriate to bury them together, so just dig another one.

This time it was nearby, and it was excavated at the door, and Hu Xiaodao went down seven or eight shovels and still didn't see the mineral salt.

This can't help but make him wonder, a room with salt mines on one side and no salt mines on the other, this is also too strange, isn't it?

Although he didn't intend to bury people in the soil and rot, Hu Xiaodao's perception told him that there must be something strange here.

Buried in his head and continued to dig, and then dug to about 70 centimeters above the ground, Hu Xiaodao's sapper shovel suddenly heard a "bang" sound.

"I'm afraid I've run into something, everyone, if Brother Dao and I dig up a treasure, you have to give a reward, this thing is not easy to sell!"

Hu Xiaodao laughed and dug the sapper shovel a few times, expanding the range to take out the things underneath. I turned through the shovel and found that it was a wooden box, the wood on the outside had almost mixed with the dirt, and there was a small box inside that had not corroded.

"Knock knock!"

stabbed a few times with a sapper shovel, Hu Xiaodao also joked with the people in the live broadcast room that don't release any ancient demons.

He took out the small box, and the handle on the box glowed green under the light of the miner's lamp overhead.

Hu Xiaodao understood that this was because the handle was made of copper, and it had begun to oxidize. If it is a few decades late, it may be completely corroded.

Carefully wiping the soil on it, Hu Xiaodao asked with a smile: "Guess what's in here, if you guess correctly, you can get a kiss from the administrator of this live broadcast room." ”
