Xiang Gong approached Hui An and the black bear, stretched out his hand, groped on the stone wall for a while, and finally found an unusually obvious crack, which could probably be stuffed into a thumb.

Touching down the crack all the way, just how tall is one person, it is the height of the stone gate, it should be here, great, and then we have to think about how to get this stone slab off the stone wall.

As long as the stone slab falls down, and the stone door is missing a side of protection, it is natural to find a way to bring it down, or when the stone slab is removed, you can find the mechanism to run the stone gate, and the trouble of the stone gate will be naturally lifted.

The sapper shovel and the dagger are obviously difficult to accomplish such a difficult task, it seems that there is another treasure bag mission, and power tools are restricted items for the time being, maybe it is time to take the risk and try gunpowder?

Gunpowder was already invented by the Chinese people during the Warring States period, and it is rumored to be related to a method called "fire alchemy" in alchemy.

Sun Simiao also recorded in detail the initial formula of gunpowder configuration, two taels of saltpeter and sulfur, and after burying them in the ground, three lit insect-eaten soaphorns were put in, thinking that sulfur was ambushed by fire.

This is the original gunpowder formula, and later derived the "Fu Huo Alum Hair" that replaces the soaphorn with aristolochia, in any case, since it is an item that has existed in the past, it must not be overrun, right?

However, it will take a while for the number of treasure bag tasks to be refreshed, and Xiang Gong has nothing to do, and rammed the unburned wooden handle of the torch that has not burned out into the crack with a sapper shovel.

Several people looked at Xiang Gong's movements, their faces were all circled, and then they smacked their tongues.

Xiang Gong came and went, always holding wet clothes and suddenly appeared, and after wringing out the clothes on the wooden handle, they disappeared in an instant, and Hui'an Walker was so shocked that his tongue was about to swallow.

"Is he showing us that he knows the Five Elements Escape Technique?" Hui'an walkers are full of sourness.

"Well, if I could, even if it was only a little, I would show it." The black bear is not shy about it.

"No, what do you think he's doing?" Li Changgeng is more knowledgeable.

When Li Changgeng said this, Hui'an and the black bear also began to pay attention to Xiang Gong's every movement, but after watching it for a long time, they still didn't find anything, and they couldn't help but shake their heads.

Li Changgeng looked at Xiang Gong and couldn't help but add a little more to his appreciation, and said with a smile: "Haven't you seen the logs that fell into the river?" Have you ever noticed that logs swell when they encounter water? ”

Listening to Li Changgeng's words, Hui An and the black bear began to stare intently at the wooden handle that had been soaked by Xiang Gong again and again, although they had been in the cell for a long time, they had become accustomed to seeing things in the dark.

However, the dim line of sight still made it difficult for them to tell whether the wooden handle had swelled or not, and after staring for a long time, the black bear couldn't help but complain: "What's the use of this method?" ”

Suddenly, Xiang Gong threw his clothes on the ground, sat on the ground with a puff, and said with a sigh: "Damn, I'm tired to death!" ”

"Eh, Brother Xiang, does your method really work?" Still curious, the black bear stepped forward and asked.

"Well, I'll try again tomorrow, anyway, it seems ...... now" Xiang Gong paused.

"Works?" The black bear asked.

"It's useless,!" Xiang Gong resented.

The black bear tilted its body and almost lay there, laughed dryly, and moved to the side.

It's the third day, and everyone's chests are pressed against their backs when they're hungry.

Xiang Gong had to weigh it carefully, whether to continue to try it with this method, or directly put gunpowder.

If you continue to use the method of wood expansion, it is obvious that it will be effective, and then cooperate with the principle of thermal expansion and cold contraction, make a pile of charcoal and light it on the side of the slate, and then pour some water on the slate when it is hot enough.

It is very likely that the slate after thermal expansion and cold contraction will produce cracks, and then it will be broken, which will definitely accelerate the destruction of the slate, however, first, this will be a waste of physical strength, and second, if it is useless, it will waste another task opportunity.

Forget it, let's fight, although the danger factor of gunpowder is a little greater, but at least one chance to leave a treasure bag mission, and if you don't eat, these people will starve to death!

Just do it, ask for gunpowder, the task is not too complicated, but it requires to obtain seeds and plant them in Longzhong, looking at this task, Xiang Gong is quite painful.

In this way, there is another chance to waste a mission, there is nothing wrong with obtaining seeds and planting, anyway, you have to plant sooner or later, but why can't you wait for the farmer to become a pawn before eating, right?

It's important to fill your stomach first!

Helpless, the task is such a task, the opportunity to do the task of not doing a treasure bag has been used up, bear with it for another day!

The task of obtaining seeds is very simple, Xiang Gong has done it by dividing it by two, looking at the small seedlings in his hand, Xiang Gong doesn't know what kind of seedlings they are and what they can grow in the future.

Forget it, this kind of seedling-carrying crop, Xiang Gong knows the method of planting, and everything is the same, digging small pits in Longshang, pressing the seedlings into it, and burying the roots into the width of nearly two thumbs.

Then he continued to absorb water with his clothes sadly, pouring it one by one, and after being busy for a long time, Xiang Gong, who was sweating profusely, could finally take a rest.

The gunpowder in hand is really the most primitive earth gunpowder, the dark brown is a little black, Xiang Gong is another tragedy, the gunpowder is there, but in the absence of restricted space, there will be no explosion!

What's the use of gunpowder without an explosion? Watching fireworks?

There was no way, another day passed in a flash, Xiang Gong learned from the pain, decided to do the task to the end, and appealed to a number of fist-sized clay pots, and the content of the task turned out to be hoeing grass again.

Niang, Xiang Gong doesn't look like he is traveling to the west to learn from the scriptures, but it seems that he has come to the mortal world to go west to reclaim wasteland, but when he entered the plantation space, he was stunned by the scene in front of him.

The overgrown leaves are green and green, and the big leaves are almost the size of a palm, and the more Xiang Gong looks at it, the more familiar he feels, how can it be so similar......

What about leaves like sweet potatoes?

According to reason, sweet potatoes, also known as sweet potatoes, were introduced to the Central Plains in the Ming Dynasty.

Well, it seems that the so-called overrun of the system refers to something that the entire mortal version of Journey to the West does not have in this era, although sweet potatoes were introduced late, but they already exist at this time, so they are not overrun.

Maybe you can use this in the future, but, looking at this rally, Xiang Gong is very skeptical, maybe tomorrow when you enter the plantation space, there will be sweet potatoes to eat, oh my God!

The plantation space actually has the effect of accelerating the growth rate of crops, that is not ......

I didn't want to do so much, Xiang Gong immediately started hoeing, thinking of the magic of the plantation space, Xiang Gong was full of energy, and soon the grass hoeed out, the clay pot was in hand, and next, it was time to break the door!

Looking at the delicate clay pots, Xiang Gong was very much looking forward to seeing how amazing the effect of the first landmine in the entire mortal journey to the west world, or grenade, that he made with his own hands.
