There is no need to think about the high-difficulty task for the time being, only more than half of the unlocking permissions have been obtained, and the medium-difficulty task is a world-class cave exploration mission, and the estimated danger level is similar to the task of the barren mountain ancient temple, and he doesn't want to touch it at the moment.

In the end, there was only one low-difficulty mission left for him to choose from, as well as the remaining three limited-scenario missions.

However, Han Du's goal tonight is very clear, just for the exploration funds, so without hesitation, he clicked on the "view" behind the low-difficulty task, and a new mission appeared.

Han Du didn't even look at the task introduction carefully, and directly confirmed that he had received this task, and a large text introduction covered the system page:

The location of the disappearance, the location that cannot be found on the map, in the early days of the founding of the People's Republic of China, there was a large engineering area at the foot of the eastern mountain of Yandang Mountain, which was designed to provide production assistance for a state secret mission, because the construction began on July 15, so it was ordered to be the 715 project area.

It was a time when the people were full of enthusiasm, and how many people left their youth there incognito, and to this day, how many things that happened there are unknown.

The host's mission is to arrive at the east side of Yandang Mountain at ten o'clock tonight, find the old site of the engineering area, and find a lost Medal of Honor within two hours, its owner is a simple worker in the engineering area, has turned into white bones, and is looking for this Medal of Honor before he dies, burying it with the owner, and comforting his soul in the sky.

Special reminder, this mission is the most difficult in the low-difficulty mission, with a certain degree of danger, if you can't find the Medal of Honor, but survive two hours, it is still considered to complete the task, but the price is that the original 20,000 yuan expedition fund reward will be halved.

The last one made Han Du a little painful, he was very short of money, if 20,000 yuan was less than 10,000, it would make him unable to sleep for several days, so he had to complete the task within two hours anyway.

Now that he had received the new mission, Han Du naturally began to prepare to go, and it just so happened that the expedition equipment he bought online had already arrived.

He left to go downstairs, the leopard was lying on the ground, and there was some excrement next to it, and Han Du, as a shovel officer, immediately found tools to clean it up.

It was estimated that the leopard was hungry again, so Han Du took out another piece of rib meat from the cardboard box and threw it to it, and then began to pick up the remaining rib meat inside, ready to put it in the Xiaoice box on the first floor.

At this moment, an unexpected scene occurred, a line of words suddenly appeared on the top of the head of the leopard gnawing on the pork ribs, and the system read it: "Ding, favorability +50!" ”

Han Du immediately said that he was stunned, he was really a foodie, but he fed it pork ribs twice, and his favorability increased by 50!

Now that he has calculated, Han Du has accumulated 64 favorability points from the leopard, and it is not far from accumulating 100 favorability points to completely unlock the identity of the leopard's team member.

The leopard was unaware of these changes, still gnawing on the ribs on the ground with relish, while Han Du carried the remaining ribs and put them into the Xiaoice box on the first floor.

The location of the refrigerator was under the stairs leading to the second floor, just stuck in the corner.

Next, Han Du went to open the largest cardboard box, and when he opened it, he could see that it was full of various expedition equipment, such as headlamps, steel helmets, strong flashlights, folding shovels, compasses, climbing hammers, water bottles, military backpacks, and so on.

At the top of these things, Han Du saw at a glance the imitation military bow and crossbow that had been given away.

This imitation military bow and crossbow is small, and it is still closed in the hand, with ten arrows. Han Du loaded a crossbow arrow on the crossbow, learned the actions in the online video, aimed at the cardboard box containing snacks, held the bow and crossbow with one hand, and pulled the firing trigger with the other.

Han Du personally operated it, and he clearly felt the power of this imitation bow and crossbow, if it was shot in a person's chest, it would definitely be able to shoot through the flesh and bones.

He rummaged through the snack box, and found that the crossbow arrow had shot through two bags of biscuits, a chicken leg, three packs of Weilong spicy strips, and finally shot through the other side of the cardboard box, sticking straight into the wall.

After pulling out the crossbow arrow vigorously, Han Du found that the arrow was still very sharp, indicating that the quality of this imitation military bow and crossbow was not bad.

Han Du was going to carry out the expedition mission of the 715 Project Area tonight, just to try the effect of this bow and crossbow, he picked out a slightly smaller backpack from the purchased expedition items, first loaded the military bow and crossbow into it, and then put the steel helmet, headlamp, strong flashlight and a folding shovel into it.

In addition, he also picked out the compass and put it in his pants pocket, and it was necessary to bring a compass for field work.

After preparing these things, Han Du suddenly heard a cooing sound, and when he touched his stomach, he realized that he was hungry.

He hadn't finished eating at night, so he took out a bucket of instant noodles from the cardboard box containing snacks and soaked it, and then found out the biscuits, chicken legs, and spicy strips that had been shot by the crossbow arrows and ate them, replenishing so much energy, Han Du's whole body became more powerful.

He looked at the time, it was 9:03 p.m., and it was time to go.

Han Du put on his backpack and greeted the leopard, and the sturdy man ran out obediently.

"Leopard, follow closely, take you out for activities tonight."

Han Du locked the door of the rental house, found a shared bicycle not far from the door, and set off immediately after scanning the code. The leopard ran after him all the way, but it even often ran in front of Han Du, if it didn't like to run back and forth, left and right, Han Du would have been left far behind by it.

The destination of this mission, Yandang Mountain, Han Du also knows, it is in the southwest of Guqing City, and it can be reached by bicycle in the past forty minutes.

The road was very smooth, there were street lights along the way, and at 9:45 he arrived at Yandang Mountain, Han Du hid the shared bicycle in the grass on the side of the road, planned to ride it when he came back, and then walked towards a hill more than 300 meters high in front of him.

This hill is Yandang Mountain, although it is not very famous, but the mysterious 715 project area is at the foot of its mountain, and the vicinity was designated as a military restricted area at that time.

In order to identify the direction, he took out his compass and looked at it, the pointer pointed to his left hand, which meant that directly in front of him was the west, but from the perspective of Yandang Mountain, this direction was the east side of the mountain, so he only had to go straight over.

When he reached the foot of the mountain, the time for the mission had arrived, and it was exactly ten o'clock in the evening.

Han Du took out the steel helmet from his backpack and put it on, put on the headlamp, pressed the light, and then took out the folding shovel and opened it, holding it in his hand as a tool.

He looked around at the foot of the mountain, and there were no trees, there were weeds growing everywhere, and there were no buildings at all, not even a little remnant of masonry and rubble.

Han Du stood in place and looked around at the dense weeds around him, realizing that the situation was different from what he expected, and it was likely that after the completion of the state's secret mission, this 715 project area was also razed to the ground, completely eradicating the traces of its existence on the ground.
