Early morning.

After Wang Feng got up, after eating, he arranged for Qi Xue and others, who were originally clerks in Wanbaolou, to make drawings, and make some drawings of beds, and then let them build the house according to the drawings.

And these survivors followed Qi Tian and they dug a moat outside the city to protect the entire Xuantian, and according to Wang Feng's instructions, they had to dig at a distance of five hundred meters from the diameter of the Xuantian Outer City.

On the one hand, once the zombies break through the moat, they can use this distance to defend, so as not to reach the outer part of the Xuantian City just after exiting the moat, on the other hand, it is to wait for the right time to expand the Xuantian, of course, when the Xuantian is strong to a certain extent, the moat will have to spread outward.

Now this moat is only because it adds a defense, Xuantian is not strong enough now, and there must be an external force to enter to enhance Xuantian's defense.

As for how to introduce river water Wang Feng already has a way, because Wang Feng found a good thing in the system store, that is the conversion stone, the transformation stone, as the name suggests, is to convert a thing from here to here, the better the conversion thing, the more expensive the price, as for the conversion person has been as high as tens of millions, this is only the lowest.

As for the conversion stone of converting a river water, there are only hundreds of thousands of points, but the time of the conversion stone can reach up to five seconds, and if he wants to fill the entire moat, Wang Feng prepared three conversion stones to convert the river water.

As the name suggests, the conversion stone is used to convert things, which is similar to the purpose of the portal, but it is not as domineering as the portal, and the transformation stone that Wang Feng bought is still the lowest-level transformation stone, which can only be used to convert some ordinary things.

Once the conversion stone is opened, it will form a rectangular opening that is one meter wide and two meters long, and has a strong suction, once the moat is dug, Wang Feng throws the transformation stone into the lake, and guides the lake water through the conversion stone.

Everyone began to dig, more than 200 people seemed to be a lot, but if they wanted to dig through the moat that protected the entire Xuantian, it was still difficult to complete it in one day, so they could only dig as much as they could, and how much they could dig.

Wang Feng was sitting on the sofa in the main city hall and constantly studying the drawings developed by Qi Xue and them, there are currently three kinds of drawings, the first is a wooden gillnet used as a defense, used to make traps near the moat, and the second is a suspension bridge, after all, the moat and the opposite side are different from each other, there must be a suspension bridge as a bridge, and when the zombies approach and put away the suspension bridge, the moat becomes a natural barrier.

The third is the house, the simplest kind of house, the whole process is accumulated with wood, and there are some small parts as fixation in the middle, and the original small parts are also to be designed, but Wang Feng removed this in order to save time.

Xuantian is currently level 1 (200/100) and has reached the requirements for upgrading, once Xuantian is promoted to level 2, Xuantian will open a miscellaneous workshop, which contains items such as making nails, because the third stage of the task has not been completed, so there is no way to upgrade.

The third stage is to survive for three days after the world changes, and the task can be completed automatically, so as long as it can survive three days, everything will not be a problem to build a house, and this small part naturally does not need to be redesigned, to ensure that Xuantian is foolproof, the top priority is to design a defensive weapon that can make Xuantian's defense more powerful.

"Shopkeeper, let's see if it works!"

Qi Xue took the drawing she had just drawn, handed it to Wang Feng, and said.

Wang Feng took the drawing, thought for a moment, and said: "Although this boiling oil is a good defensive weapon, as long as the zombie does not hit the brain or cannot be fatal with one blow, it will not die, although the boiling oil is a wonderful weapon, but we have no oil!" ”

"Oh!" Qi Xue nodded, put the drawings aside, returned to her seat, and began to discuss with Xiao Qi Yaer and the others.

Qi Xue still keeps the drawing of boiling oil, and if you can't use it now, it doesn't mean that you won't need it in the future, so stay it first, just in case you need it.

Wang Feng picked up these drawings, these chapters are marked very clearly, even some production methods are recorded, and there are still some differences between Wang Feng and this Wang Feng, this Wang Feng is very clear, in ancient times, the two siege and defense sides preferred to use this to repel the enemy army.

But the most important thing is missing here, that is, oil, the oil you eat is not good, you must have the kind of oil that can burn, although Wang Feng has gasoline, although I don't know what model, but it can also burn, but Wang Feng will not take it out.

Because if this is used in the military, it can be a waste of points than those bullets, and it will be at least hundreds of thousands better in a battle, which is just the price of gasoline alone, plus other things, at least two million starts.

"Wang Feng, my father, why haven't they come yet."

At noon, the group was eating, and Mu Yuqing sat at the table, looking at the delicious dishes without any appetite, with worry on her pretty face.

Wang Feng stopped his movements, swallowed the food in his mouth, and said, "Otherwise, I'll let No. 1 go to the front to take a look, maybe I'm already on the way here." ”

"That's all there is to it."

It was already noon at the moment, and it was absolutely impossible to rush to the Red Kite base to come back, so he could only pray that they were on the way to come, but Mu Yuqing was not steady, he knew his father's personality, and it was difficult for him to give up the Mu family's property and come here.

After all, nothing happened, no one could give up easily, it was not easy for Wang Feng to do this, Wang Feng already knew the result when he persuaded Ye Qingyun, but he still couldn't help but try, and the result was predictable.

And Mu Linchen is almost the same as Ye Qingyun, who is willing to easily give up his assets and come to someone else's roof without any circumstances, but Wang Feng still tried, after all, Mu Linchen is also his father-in-law, he can only try to persuade him, it is impossible to kidnap him!

After eating, Wang Feng asked No. 1 to go to the Red Kite Base and the Blue Grassland to check if there was any trace of Mu Linchen and his party.

And the survivors still began to dig the moat, although they did not know why, but they knew that they could protect themselves by doing so, so they did not complain at all, but were full of energy.

At first, Wang Feng wanted to introduce the water of that river into the moat, but then he thought that the river could also indirectly protect Xuantian, so Wang Feng would look for a farther lake.

After investigating, he found that there were few zombies here, so Wang Feng decided to carry water here, and then returned to the Xuantian moat, quietly waiting for the night to fall.
