Forget it, let’s not consider these for now. At least this strange thing has not happened to their survivors in District 188.

"You know Xu Xin, Zhang Daoguang has discovered that Ma Hongwei's name is secretly in the channel in District 187. He is furious now and sends private messages to us, the top ten, asking me to find the murderer, I'm so laughing to death, let the murderer find the murderer, haha!"

"...I was cheated by you..." Ma Hongwei's voice was a little helpless and depressed.

"... Just don't show it." Xu Xin also smiled a little. He was a little interested in Zhang Daoguang.

"Don't worry, I can't reveal it!"

"Ma Hongwei, you can make a few more control panels." Xu Xin said to Ma Hongwei, "There are green-level crossbows, make fifty first, the materials are enough." As Xu Xin said that, he traded a bunch of materials for him, green-level fine woods and animal tendons.

"Enough." Ma Hongwei nodded, "I will trade you if I do it."

After hanging up the call, Xu Xin thought for a while and placed a control panel next to the tree house screen.

The control panel itself can be seen from all directions and is placed next to the window. It is more susceptible to attack when operating, so it is better to place it in a position within.

When he cut the panel, it seemed that the scenery around his tree house was displayed on the panel as he had taken aerial photos from above. The heavy crossbows he placed on the tree house could already be operated through the panel.

However, the heavy crossbow on the wall to the west was gone because his heavy crossbow was placed on the first floor, and the west was already wrapped in the canopy of his newly planted banyan tree, expanding a new space, and the original heavy crossbow disappeared directly.

Xu Xin tried to control the heavy crossbow to attack a tree a hundred meters away.

The sound of the heavy crossbow launcher was immediately heard outside the tree house. Then, a loud "click" sound was heard. On the control panel, the tree he clicked on had been accurately hit by the heavy crossbow and was directly broken.

"Yeah!" The cocoa on the sofa was awakened by the sudden sound outside the tree house and jumped up from the sofa.

Yin Wang and Mimi also stood up vigilantly. Only Afu turned his head, looked out the window, and then continued to hang it on the window ling.

Xu Xin comforted them, then looked at the control panel again.

"This thing is really amazing." Xu Xin exclaimed.

Although he has seen such an operation with Qi Xuefei, it is the first time he has operated it himself. It feels extremely silky and is really a very safe tool.

The attack range of heavy crossbow controlled by this panel is not determined by the panel, but by the heavy crossbow.

His tree house is equipped with heavy crossbows of different levels. If you click on green-level heavy crossbows or blue-level heavy crossbows, a faint red circle will appear to indicate the shooting range. The shooting distance of blue-level heavy crossbows is obviously about twice that of green-level heavy crossbows.

It seems that even for crossbows loading explosive crossbow arrows, the blue level is stronger than the green level because it can hit farther.

For blue-grade heavy crossbows, Ma Hongwei can only make blue-grade wooden heavy crossbows now. It requires blue-grade wood. This thing needs to be planted by itself. Although there are many seeds and many people can plant it by themselves, because not many people use blue-grade soil to plant birch trees, blue-grade wood is very lacking.

But it would be easy to say when he develops a blue-grade iron ore heavy crossbow. Although for others, blue-grade iron ore steel blocks are more difficult to obtain than blue-grade fine woods, they are not short of them. With Li Wenxi and him, this kind of resource is very abundant.

Now, let Ma Hongwei make some green-level heavy crossbows.

Now there are two left in hand, Xu Xin first traded it to Ji Chaoyang and Li Wenxi one.

Ji Chaoyang immediately agreed to the transaction.

Li Wenxi is still outside and cannot pass the transaction, but she immediately sent a voice message to Xu Xin.

"Can this control panel be mass-produced?" Li Wenxi asked in surprise when he came up.

Her voice had echoes, obviously in the mine. If it weren't for the mine, she would definitely send videos instead of voice.

Xu Xin told her that it was not possible, so she could only provide the explorer first.

"Loops? It seems like a planting house on Zhao Xiaochuan. Why would you let him plant blue-grade logs?" Li Wenxi suggested.

"No, the pine trees are nearly ten meters high and cannot be planted inside the house. They can only be outside the house. Planting the house is useless." Xu Xin shook his head.

Li Wenxi did not have a planting house, but just planted some vegetables and fruits casually, so I didn’t expect this to be normal.

"Yes. Then this control panel can only be used as high-end weapons and equipment first."

"By the way, you can dig more saltpeter today. We are going to start making large quantities of explosive crossbow arrows. Is your saltpeter mine still sufficient?"

"You still have to worry about the reserves. Don't worry, there are so many, and supplying them to the whole district is no problem!" Li Wenxi promised.

"Supply the whole district, won't you be exhausted?" Xu Xin joked.

"Ah? You really have to supply the entire district..." Li Wenxi's tone was a little weak, "Don't, I'm really exhausted..."

"Well... I will pick as much as I can today. I will send you some labor force in the afternoon and let Lou Feier help you too."

What Xu Xin said was naturally Leyou. Leyou should not have any special abilities. Xu Xin did not intend to transplant his tree house to him, and sent it to Li Wenxi to mine.

Moreover, since you already know that there will be a crisis tomorrow, you must be well prepared, such as a weapon that can exert its outstanding power in anyone's hands.

"Is that so urgent? That...why are you here to help?" Li Wenxi didn't know that there would be a beast tide tomorrow, and her mentality was relatively relaxed. She wanted to be with Xu Xin so relaxed.

"I also want to go find a friend, but I have something else to do today."

Xu Xin was about to tell her what would happen tomorrow, but Ji Chaoyang told everyone about what might happen the next day in the Explorer Group and the regional channel.

Li Wenxi also noticed it and immediately exclaimed: "Oh my God, there will be a tide of beasts tomorrow?! You already know?"

"Well, so come on, your saltpeter mine is very important, it is related to the survival rate in our area."

"I'll collect saltpeter now and bring Yajun with you! Come on, too!"

"good."

After disconnecting the call, Ma Hongwei had traded him ten control panels and fifty heavy crossbows directly.

At the same time, Xu Xin heard Lou Feier's shouting under the tree house.

"Xu Xin, here, let me go up!"

Xu Xin controlled the roots of the tree house and pulled her up.

"What are you here to do? Didn't you ask you to find a Liyou?"

"I came for this... That's right, can your Silver King lend me some money?" Lou Feier glanced at the Silver King who was lying in the corner to rest and asked tentatively.

If the Silver King could take her there, she wouldn't have to run more than ten kilometers by herself.

"Silver King, is that OK?" Xu Xin also wanted Lou Feier to hurry up and end the time and go to help Li Wenxi dig together, so she looked at Silver King Dao.

"Aowu!" The Silver King stood up.

"Okay!" Lou Feier ran to the Silver King and touched its head.

"Bring Silver King with you, come back within an hour." Xu Xin gave Lou Feier a time limit. After all, he still needs Silver King to take him to the border of the reserve to kill vines today.

In addition to saltpeter, the raw materials for explosives also have the juice of mutant vines. He needs to go to the edge of the safe area to kill the vines, collect some juice, and at the same time he can get more points.

Points can be exchanged for blue-grade fertilizer, giving birth to blue-grade pine trees, and obtaining blue-grade logs. Slaying two birds with one stone, killing two birds with one stone.

"No problem!" Lou Feier was very confident and took the Silver King down.

"You..." Seeing that Lou Feier had already gone down the tree house, Xu Xin was about to say what she wanted to say.

Just as she was about to remind her that she must sit firmly and hold on, she did not sign a mount contract with the Silver King, if she didn't hold on...

"Wow—ah! It hurts so much... Silver King, please wait!"

Sure enough, it fell down.

Xu Xin shook her head and stopped caring about her.

He traded a control panel for everyone in the Explorer and four treehouse crossbows.

As for why there are four, because the tree houses are on all four sides, and each side may be attacked, of course, four are needed.

Whether it is [Explorer] or the regional channel, it is becoming very lively because of Ji Chaoyang's words.

Wang Lei: "The tide of beasts of mutated creatures sounds so terrible!"

Wen Guixin: "What are you afraid of when the soldiers come and generals come and block the water and soil."

Qin Yunlong: "...We don't have the combat power of yours. By the way, what is your ability? Can you tell me now?"

Qi Xuefei: "I hope those wild beasts don't attack the tree house. However, you have been meeting for so long, don't you know Gui Xin's ability?"

Qin Yunhu: "She can solve other survivors with just fists and feet."

Wen Guixin: "...My abilities are not very good, they are quite complicated, and I can't help you, so I won't talk about it for now..."

Zhao Xiaochuan: "Brother Xin sent a bunch of things! Control panel and tree house crossbow?!"

Xu Xin introduced them to the function and told them that they now need to produce explosive crossbow arrows in large quantities, so they need juice from plant vines.

Wen Guixin: "I'll collect vine juice!"

Li Wenxi: "Leave the saltpeter to me, ah! The 100-fold explosion rate is coming again!"

Wang Lei: "Hundred times the explosion rate? What does it mean? Hundred times?!"

The four people who had already met Xu Xin did not explain their abilities carefully to them.

Xu Xin: "First prepare for tomorrow's things. When we explorers hold a meeting in the evening, we will describe our abilities and then discuss our respective positionings. It is meaningless to hide it like this."

Wen Guixin: "Okay..."

Zhao Xiaochuan: "Do you know the abilities of Brother Xin and Brother Chaoyang? Excited!"

On the regional channel, everyone has lost the calmness and urgency that has been like before.

"I just bought twenty more pieces of tree house armor! If I can't beat it, I will just use the armor pile to defend and hold on!"

"Good idea, I do the same!"
