Duan Lang took Hatsune and walked quickly into the laboratory.

Duan Lang hadn't been in the lab for several days, there weren't enough materials, and the self-healing speed in the lab was very low.

However, Duan Lang was not in a hurry at all, he was confident that he would bring back enough steel and refined copper from Lubanmen.

"Hatsune, what are the synthetic elements on Earth that are used to purify natural gas?"

"It's synthetic xenon-radon!"

"I remember there were about five kilograms of synthetic xenon radon in the lab?"

"Yes!"

"If I need a synthetic xenon-radon part of this model, how long will it take?"

"Normally, one minute is enough, but the lab is so damaged that it takes about five minutes. ”

"The sooner the better!"

"Yes!"

Normally, xenon and radon are two noble gases, but when they are synthesized with the latest technology on earth, they become solid.

Originally, xenon and radon are noble gases and do not react chemically with substances.

However, after fusing into xenon-radon, it becomes very active, and any combustible gas with a combustion value of less than 40,000 KcalNm3 will have a violent chemical reaction with xenon-radon, instantly consume all energy and become solid!

Among natural gases, only pentane has a combustion value of more than 40,000 KcalNm3, and other gases, such as methane and ethane, are far less than this value.

Taking advantage of this characteristic, super natural gas composed entirely of pentane is produced on earth, and the combustion value of super natural gas is 40,428 KcalNm3, which is more than four times the combustion value of ordinary natural gas!

Four times the heat energy is enough for Lubanmen to smelt fine steel and copper.

Five minutes came quickly, almost stuck in seconds, and Hatsune was successfully completed.

"Master, the xenon and radon parts you asked for are ready. ”

"Okay, Hatsune, take a good look at the house, the master is gone. ”

"Yes!"

Duan Lang was satisfied with the xenon radon parts and walked out of the laboratory quickly, along the way, Duan Lang found that some fine solid dust appeared on the xenon radon parts.

Duan Lang knew that this was a trace amount of combustible gas in the air that came into contact with xenon and radon components and reacted.

"Purple gangway!" Duan Lang shouted at the purple flying boat.

The purple flying boat put down the purple gangway very sensibly.

Duan Lang stepped on the purple gangway quickly, and muttered in a small voice, this purple gangway is too long, and it is so tiring to climb a flying boat.

Hearing Duan Lang's muttering, the two super-grade immortal artifact spirits on the purple flying boat were shocked, and the instrument spirits at the stern of the boat hurriedly controlled the purple gangway to shrink!

Just in the blink of an eye, Duan Lang boarded the purple flying boat.

Duan Lang was stunned, it turned out that the purple flying boat still had this kind of effect? If it was flying up and down at this speed, it would be acceptable.

"Let's go, Lubanmen!"

Sou!

The purple flying boat teleported and arrived at the tarmac of the Lubanmen flying boat.

"Childe, please board the small flying boat. ”

Duan Lang bowed slightly, and walked towards the small flying boat that landed on the purple flying boat, muttering as he walked.

"It would be nice if the Purple Boat could be turned into a small flying boat and could be carried around, so there would be no need to bring an extra small flying boat. ”

Hearing Duan Lang's words, the soul of the super-grade immortal weapon on the bow of the boat moved, a ripple flashed, and the purple flying boat became smaller at a speed visible to the naked eye, and soon, it became the size of a small flying boat!

And the small flying boat that landed on the purple flying boat was crushed by the power of the ripples!

Duan Lang's face showed joy, this purple flying boat still has this function? It is like a golden hoop stick, it can be made bigger and smaller? I don't know if it can be put in my ears?

Duan Lang gestured to the size of a matchstick and asked, "Purple Flying Boat, can it become so big?"

Airplanes!

A ripple flashed, and the purple flying boat really became the size of a matchstick!

Duan Lang was so happy that he grabbed a matchstick-sized purple flying boat and stuffed it into his ears!

Then, this guy knows, Journey to the West is all a lie!

Even if the golden hoop stick really turned into a matchstick, it wouldn't be able to fit into his ears! Duan Lang's tears were about to fall......

Li Hongru was completely confused, what is this? I have never heard that a flying boat can become bigger and smaller!

"The purple flying boat has become the size of a small flying boat. ”

Airplanes!

The purple cloud floated up from Duan Lang's palm and became the size of a small flying boat.

Duan Lang was so happy, it was like discovering a new continent, if the Purple Flying Boat could be carried with him and could change in size, he could go wherever he wanted to play in the future!

After Li Lichuan is cured, he is going to go to the elf forest to see the elves, and I heard that the women of the elf clan are very beautiful......

"Great Elder, what are you doing in a daze? Why don't you board the boat soon?" Seeing that Li Hongru was stunned, Duan Lang reminded him.

"Oh, oh......" Li Hongru hurriedly boarded the boat, he decided, don't follow Childe alone if it's okay in the future, Childe will surprise him from time to time, he is afraid that his heart will not be able to bear it......

Sou!

The purple flying boat flew to the smelting room in an instant.

In the smelting room, it was still a hot scene.

Jin Qingfeng, Li Tianyun, and Li Tianyu stood quietly next to a smelting furnace, and Lu Qianshou stood aside with a smile on his face.

"A few elders, the smelting room is very hot, why don't we go to the guest room and wait for the Duan Holy Lord?Luban Gate is thousands of miles away from Mangdang Mountain, and it is impossible to come back in a quarter of an hour!"

As soon as the words fell, Jin Qingfeng, Li Tianyun and Li Tianyu were in high spirits.

"Childe is back!"

The three of them walked quickly towards the gate of the smelting room, Lu Qianshou on the side was speechless, are the Huanggu Duan family all some neurotics?

The Holy Lord is like this, and so are the several elders, no wonder they will become the public enemies of the entire Heavenly Sealing Realm!

With a bang, Li Hongru pushed open the door of the smelting room, and Duan Lang and Li Hongru walked into the smelting room one after the other.

"Childe. ”

"Childe is back. ”

Duan Langchong bowed slightly, and then walked quickly towards Lu Qianshou: "Master Lumen, I'm back, it's not more than a quarter of an hour, right?"

Lu Qianshou was stunned, from Duan Lang's departure to his return, it wasn't even half an hour, right?

This surnamed Duan, did he go around Luban Gate?

"Holy Lord Duan, I don't know how to solve the problem?"

Duan Lang smiled slightly and shook the xenon radon part in his hand: "As long as this xenon radon part is connected to the ground fire intake pipeline, the problem can be solved." ”

Lu Qianshou is also drunk, this surnamed Duan has a problem with his brain, right? If the problem is so easy to solve, as for the more than 30 years that have plagued him?

What's more, this surnamed Duan has not measured the size of the ground fire pipe at all, how can this part be installed?

Since the surname Duan likes to be funny, let's play with him!

"I'm going to close the Earth Fire Valve of the No. 6 furnace and ask Holy Lord Duan to install the parts that I brought over to the Earth Fire Pipe. ”

Crunchy.

Lu Qianshou took matters into his own hands and closed the ground fire passage of the No. 6 furnace, and then made a gesture to Duan Lang to please, in his mind, the xenon and radon parts would definitely not be able to be installed.

After a while, just wait to see the jokes of this Duan Holy Lord!
