One of the wetlands that has not received official attention is the Qihe Plain Wetland, which is similar to the famous Sanjiang Plain wetland.

Han Du and their car stopped in an open area, and after they came down, they saw Situ Boshan burning paper money at the edge of the wetland, which turned out to be a tribute to the three subordinates who died in the wetland swamp.

Han Du and Situ Yufeng didn't see it, at that time, a large pile of paper money was burned here, and the fire and smoke rose, Situ Boshan thought of the three right-hand men, and he couldn't help himself, and he cried bitterly here alone, for so many years, he had always wanted to find out the bones of the three of them and bury them well, but he never got his wish.

When Han Du and Situ Yufeng walked over, they saw that Situ Boshan's eyes were still wet red, obviously he had covered up, but he couldn't remove the traces at once.

"Grandpa."

Situ Yufeng shouted, feeling a little uncomfortable, grandpa is so old, and secretly crying like this for these old things, it really shouldn't be.

Situ Boshan walked over from the pile of paper money that was about to be completely burned to ashes, and nodded to his granddaughter and Han Du with a reluctant smile.

"All this gear for me?" Han Du pointed to a Ford pickup truck parked on the other side, with a body in the back and full of objects.

"Yes, Handu Xiaoyou, let's go over and have a look." Situ Boshan took the lead and walked over.

Han Du and Situ Yufeng followed.

"You see, I have purchased a batch of things such as oxygen masks, portable compressed oxygen packs, full-body waterproof leather suits, duck paw scatter shoes, etc., which should be useful to you."

These things were prepared by Situ Boshan not long ago, and there were a large number of them, and at that time he had commissioned an expedition from other provinces to search for the remains, but after the people of this expedition came to see the site, they resolutely repented and were unwilling to accept Situ Boshan's commission.

The reason for this is because they find this misty land dangerous.

"Very good, the things are quite complete, it seems that Grandpa Situ has put a lot of effort into this place." Han Du picked up a transparent oxygen mask from the car body and looked at it, and didn't call Situ Boshan again, which seemed too rusty.

"Yes, my grandfather has also done a lot of research on that swamp, and if I haven't seen him at home all these years, he must have studied the swamp of the so-called land of death here."

Situ Yufeng stretched out his hand and pointed to a large cloud of white mist five hundred meters away.

Han Du squinted and found that the place looked a little different from the situation spread in the mouths of the people, because the white mist was actually mixed with a small amount of pale green gas, which was a substance that could not be fused with the white mist, and it seemed that the two gases were denser than air, making them sink and it was extremely difficult to rise and float away.

Maybe these pale green gases are poisonous gases, and of course those white fogs may also be poisonous, and judging by common sense, these gases are coming out of the ground, indicating that there is something strange and unknown beneath the swamp shrouded in it.

The terrain where this gas is located also has a characteristic, backing the Agate Mountain, blocked by the extended mountains on both sides, which is equivalent to a pale green white mist in a huge valley, so that they can gather without being blown away by the wind.

Of course, there was also a strong wind that blew away a small amount of gas and blew it in front of Han Du and them, smelling a faint pungent smell inside, and a suffocating stench.

Fortunately, they were five hundred meters away from the fog, and by the time the gas drifted over, it had been diluted to the point that it was harmless to humans.

"It's so good, I don't know what poisonous gas is in that white mist, Grandpa Situ, you have studied it, please tell me the details inside, it will be very useful for me to enter it safely and smoothly."

Han Du looked at Situ Boshan and asked, he actually had a rough judgment in his heart, it might contain some common toxic gases, such as carbon monoxide, sulfur dioxide, hydrogen cyanide, etc., and he didn't know which one of them was.

There is a canyon in a foreign country, and it is said that people will die in a coma when they enter it, but later investigation revealed that a large amount of carbon monoxide has accumulated in it for some reason, and excessive inhalation can cause people to die of poisoning.

"Hehe, Handu Xiaoyou, you may have been misled by my granddaughter, I haven't studied that misty land, I have been studying a large area of safe wetlands outside the misty land, through the research results of these years, I have drafted a "Seven Rivers Plain Wetland Biodiversity Research Report", which is about to be handed over to the relevant departments, hoping that they can notice this wetland that has not been paid attention to."

"Huh? Grandpa, that's not what you told me at home! Situ Yufeng suddenly seemed to have seen a ghost, "I remember that you always told me that you were studying the misty land that contained poisonous gas opposite, and you also said that you were preparing to enter it to find the remains in the future. ”

Situ Boshan's old face smiled and said: "I say this for your own good, this place is so dangerous with poisonous gas, your mother told me in private, not to let you come here with me, even if it is a safe wetland area, I can only say that the research is that poisonous fog land, you can't come with me."

You said that grandpa is at this age, how can he stand it when he gets close to those toxic gases, and naturally he doesn't have the energy to really study that area, but grandpa really wants to protect the wetlands in this hometown, so he has spent so many years of hard work. ”

Situ Yufeng suddenly felt that he had been deceived by unimaginable, it turned out that his grandfather had been wandering around the safe area of the wetland, and he had been worried about his safety, and wanted to follow him several times to protect him. At that time, because her grandfather had always been very dignified at home, he insisted on not letting him follow, and Situ Yufeng did not dare to be disobedient.

"Grandpa, you're too much!"

Situ Yufeng was so angry that he stomped his feet, turned around, looked at the distance and asked the sky speechlessly.

Han Du was also an eye-opener, his first impression of Situ Boshan completely collapsed, this is clearly an old oilman who has been polished by society for many years, and it is not the Situ Boshan he saw yesterday at all.

No wonder people often lament that life is only as it first seems.

"Grandpa Situ, you haven't studied the swamp covered in poison gas, how do you know that the equipment you bought can work in it?" Han Du couldn't help but ask, looking at Situ Boshan now is inevitably too unreliable.

"Hehe, it's not simple, I've never eaten pork, I haven't seen pigs run, I've often walked around the wetland safety range over the years, I've seen a lot, I naturally know that there is just some poisonous gas, some peat, bring oxygen, bring a gas mask, put on duck paw loose shoes, there should be no big problem in getting in and out of it."

When Situ Boshan uttered these words that he had said countless times in reverse, there was a sudden low roar from the fog opposite, as if some fierce animal lived in it.
