The light wheel beats behind Xie Tu's head, illuminating the lightless space underwater.

Xie Tu searched underwater for a while, and saw that there was really nothing left, so he slowly swam up.

After he returned to the door of the research room and put down the pile of food, Xu Shang was a little stunned, and hurriedly picked out a ham from it, and then opened the skin and put it in his mouth.

The smell of essence and starch made him hungry, and the saliva in his mouth kept secreting, and his eyes lit up.

"I ...... I've never wanted to eat ham so much, it's so delicious! It's so fragrant! Would you like one?! Delicious! It's true! Xu Shang took out a piece of ham, wiped the water off it, and then handed it to Xie Tu.

Xie Tu shook his head and said, "There is not much food, if there is a surplus, I will eat one." But after all, there aren't many of them now, so you'd better eat them. I'm fine without eating right now. ”

"You're all like that? Bigu? Is there no need for energy intake? Or do you simply not need to eat these low-energy things? Xu Shang asked suspiciously, he hadn't thought about whether these polluters still needed to eat, and he didn't need to eat in this situation.

"We draw all our energy from the calamity, and we are also a fountain of calamity, and we have reached the point where we don't need to take in energy from it, or even not at all. At most, it can only satisfy the appetite. Xie Tu shook his head and patiently explained to Xu Shang.

It's not a bad thing to know about polluters, and only when you know them can you do in-depth research.

Staying on the surface will not do any useful research at all.

"You save a little bit to eat, these are all the things you can eat in a shopping mall, and if you look for it, you have to go far away."

Xie Tu said to Xu Shang, this can be regarded as a reminder to them, don't let them eat Haisai like eating enemies, then he can't afford it.

"I understand, a porridge and a meal are not easy to come by. I won't eat nonsense, I will distribute it reasonably and not waste a single thing! Xu Shang nodded and promised Xie Tu.

"That's good. That's up to you. Xie Tu nodded, and then flew out again.

After a busy night's work, it's dawn now. The work is going on again.

"Looking at it this way, Xu Shang didn't sleep either? Spent the night researching Mithril? What a conscientious researcher. Xie Tu shook his head, This Xu Shang is really dutiful.

What Xie Tu didn't know was that Xu Shang couldn't sleep at all now, and the manufacture of those Mithril and Holy Water made him addicted to it, so he happily stared at the baking and manufacturing of Mithril.

Before, he had no talent and no place to display it, but now that he has a platform, he can't perform well?!

In the research institute, Xu Shang put a pile of food in the corner, held a lollipop in his mouth, and walked to the Mithril manufacturing area.

"Try the ratio again, I feel that I can put a little more silver, now that the material is in short supply, it would be best to be able to make more and better things with the same loss. There can't be a little waste! ”

"Okay."

"Yes."

After the three of them finished speaking, they acted immediately, without a little hesitation, and it seemed that the cooperation was very successful and tacit.

Outside, Hua Xiwu quietly approached Xie Tu, wanting to scare him secretly. But she didn't expect that when she was about to pounce, Xie Tu turned into a puff of black smoke, which made her flutter into the air, and she fell into the water instead.

"Oops!"

The mist kept fluttering in the water, as if she was about to drown.

"Don't pretend, you're third in the Moon Swimming Competition." Although Xie Tu said this, he still threw a black rope to pull Hua Xiwu out.

"Humph! Why did you go last night, I didn't find you for a long time! Hua Xiwu asked Xie Tu angrily, she was in a hurry last night.

"I didn't do anything, I just went to subdue demons and eliminate demons. It's the spoils of war. ”

Xie Tu reached out and took off the halo at the back of his head, and then handed it to Hua Xiwu.

"Here you go, I don't need it."

Xie Tu smiled slightly, the smile on his face was like a warm sunshine.

Hua Xiwu looked at the light wheel, and then lifted Xie Tu's clothes, and found that the scars from the big wounds on his waist and abdomen were still wriggling, and they hadn't really disappeared.

Then he looked at Xie Tu's face and found that there were also a few shallow marks.

"You...... Did you really go to slay demons last night? Hua Xiwu touched Xie Tu's face with some distress, she knew that if it wasn't for a very powerful monster, it would almost not hurt Xie Tu's body, and even if it did, it wouldn't leave a scar.

The polluter's physical fitness has reached a bizarre level, and after a night of recovery there are still scars, which can only be very badly injured.

"Not really! I'm so good, I'm gone! Awesome! Xie Tu took Hua Xiwu's hand away and patted her on the head.

"Get out of the way, a ghost! I can see it all! The wound hasn't healed overnight! Hua Xiwu patted Xie Tu's chest, then turned his head and said angrily: "Take me next time!" Otherwise, I'll always follow you! I don't want to be a widow! ”

"Mostly ......"

"What is the main one?!"

"It's useless to take you mainly, the Tao will hurt you."

"Why didn't it work?! If I can't do it, I'll be able to block the knife for you! Can't let you take the risk anyway! You've got to promise me! Hua Xiwu hugged Xie Tu and said angrily.

"Good, good! Bring you! Definitely with you! Xie Tu said soothingly, patted Hua Xiwu's back, and said intimately.

"Deceived Kangxi"

"Count you as acquaintances! Dog thief! Hua Xiwu snorted coldly, and then said, "Bai Miao is waiting for you, go ahead." If you want me to help, just tell me that I should be patrolling the perimeter now. After Hua Xiwu finished speaking, he pinched Xie Tu's lower back, and then flew into the distance with a light tiptoe.

Xie Tu looked at the figure in the distance, turned around and walked towards Bai Miao.

"What do you need to do?" Xie Tu looked at Bai Miao, and Bai Miao also looked at Xie Tu.

It's just that Bai Miao's expression is a little unnatural, looking like she has been fed dog food.

"How? Cut the floor slabs of that pile of buildings smooth, and then block the entrance to this building, and don't let him run into the water, there is no other way now.

The equipment is not complete, and it is impossible to get it, or it will be put on the basis of the floor. The choice is yours. ”

Bai Miao squinted at this piece of "sea", this situation is a difficult problem to rebuild the city after the disaster, a big problem.

"Then plug the gap in the building, make it an airtight whole, and then start building it higher. It's a lot of work, but it's always worth giving it a try. ”

Xie Tufei went down and cut through the floor with a long black knife!

Then the thickness and width of the floor slab began to be divided.

Xie Tu's work was in full swing, and Bai Miao was not idle, and flew down to stuff the separated floor slabs into the gaps in the building.
