While Charlotte was shouting excitedly next to her, Lin Mengchai sat alone in front of the campfire, holding her legs with her hands and her chin resting on her knees, staring at the fire in front of her motionlessly, her eyes lonely.

Su Yuntian finally breathed a sigh of relief when he saw Charlotte successfully advance, and walked to Lin Mengchai and sat down.

…… This girl has been sullen for the past few days, what's going on?

"Ah Chase, do you have something on your mind?"

Regarding Su Yuntian's question of having no foreplay and going straight to the point, Lin Mengchai glanced at him angrily: "No." ”

…… The owner gave her enough money and gave her a home with food and clothing.

Even if it is cultivation, there are enough resources.

Compared with when he first met Su Yuntian three years ago, Lin Mengchai now undoubtedly has a lot of things.

But why do you still ...... after having so many of them? I have some regrets, and I always feel that there is a piece missing somewhere in my heart.

Su Yuntian sat next to him, thought about it carefully, and felt that it shouldn't be.

By her side, she didn't worry about food or clothing, she drank dew when she was thirsty and ate grasshoppers when she was hungry...... Hey, it's okay to have big fish and meat every day, why does she seem a little depressed during this time?

Is it because the cultivation speed is not enough?

As a soul master, Lin Mengchai is a year younger than herself, just 15 this year, and her soul power has reached level 38, in terms of soul power level alone, it is similar to Su Yuntian and Dai Mubai at this time last year, and she can be regarded as a genius in a million.

Isn't that fast? It's fast, it's lightning fast.

Or, is it too lonely, the girl is pregnant?

Looking at the girl's slightly empty eyes, Su Yuntian nodded self-righteously.

"It's decided, Ah Chase, I'll give you a month's vacation, go where you want to play."

"Huh?"

After Lin Mengchai heard it, his first reaction was to tell him that he didn't want to take a vacation.

…… It's actually good to follow him every day, but if you have a holiday, you're going to be separated.

But when this sentence came to his lips, Lin Mengchai didn't know why, and he didn't have the courage to say it anyway, his lips moved, and finally he just asked: "If you have a holiday, will your salary be paid?" ”

"All benefits remain the same." Su Yuntian raised his hand and touched Lin Mengchai's little head, "You can play for a month with confidence, do whatever you want." ”

Lin Mengchai lowered his head and muttered: "If you don't deduct your salary, forget it, let you go." ”

Early the next morning, the three of them left the Royal Forest and returned to Gengxin Town.

According to the custom, Su Yuntian first went to Chaldea to see the situation over there.

In the months since the founding of the Chaldees, except for the grand event on the day of the establishment that is still fresh in people's memories, there is nothing more brilliant for the time being.

In line with the principle of lewd development, Su Yuntian asked Lou Gao to lead the team, first conduct some technical research and stress tests, and make more technical reserves to lay a good foundation for future events.

Not to mention anything else, the research and development of materials alone is divided into several departments, the first department is responsible for explosives, the second department is for the production of highly elastic stainless steel, that is, springs and firing pins, and the third department is for the production of heat-resistant and high-pressure resistant alloy steel, that is, the production of various barrels and barrels.

Not to mention, there is also a fluid mechanics laboratory, a soul guide laboratory, and so on.

The research and development of thermal weapons is one of the main directions of attack in the Chaldeans at present, but it is not the only one.

Su Yuntian spent a lot of money to buy a soul guide production line from Wuhun City, intending to let the soul guide technology flourish in Chaldea.

However, it is a pity that the progress of technology requires the support of the entire scientific system, especially basic physics and chemistry.

As a result, progress has been slow in several laboratories in Chaldea.

Because there is no science in the Douluo Continent!

Su Yuntian once lost a lot of hair for this, thinking about whether to run a school, and education should start from the baby.

He hesitated for a long time and finally gave up on the idea.

There are many reasons for this, but one of the most important aspects is that his current strength is still too weak, and he simply does not have the spare time to cultivate a generation completely.

The matter of opening a school and establishing a scientific theory and technology research system can only wait for Ah Xue to unify the continent in the future.

Today, Su Yuntian walked into the door of Chaldea and thought to himself, if nothing else, there should be no new progress in several laboratories.

Unexpectedly, as soon as he walked into the compound, he heard a loud "boom", and the roof of a laboratory was blown off, and a raging flame erupted.

Even the earth shook a little, which showed the power of the explosion.

In the core area of the explosion, Sidi, who was wrapped in heavy armor, was blown away by the shock wave generated by the explosion, and rolled twice after landing on the ground, making him dizzy.

Outside the explosion area, more than a dozen young and strong men wearing asbestos protective clothing stepped forward with water tanks to quickly extinguish the fire.

When the flames turned to smoke, Sidi took off her helmet with the help of her entourage and stood up against the wall.

His face was blackened, but his eyes were uncontrollably bright.

"Success, success!"

"I've made high explosives!"

Sidi, this soul master of the soul saint level, one of the grandmaster-level blacksmiths of the former Blacksmith Association, and now the head of the first branch of the Chaldean technical class, danced excitedly, like a child.

It didn't take long for people from several surrounding labs to pour out to see what was going on.

Lou Gao held up his big belly, walked quickly to Sidi's side, stood on tiptoe and slapped the disciple's head: "Are you stupid?" What's going on! ”

Sidi was still immersed in the joy of successful research, and even hugged Lou Gao up, and then ...... Lift high!

Lou Gao shouted loudly, scolding the disciple, and wanted to return to the ground, but Sidi's expression was like madness, and he shouted "success" vigorously, and he held up his beloved teacher Lou Gao, and began to circle the magic of love.

Not far away, Su Yuntian walked into the courtyard with Charlotte and Lin Mengchai.

After a cursory observation, Su Yuntian quickly thought of the possibility of a successful experiment.

He waved his hand and beckoned Silong who was silly next to him to come over: "Quickly check the situation in other laboratories and count casualties and property damage." ”

Silong woke up suddenly, hurriedly bowed his head and said yes, turned around and took a few disciples to count the personnel and supplies.

A quarter of an hour later, Su Yuntian, Lou Gao, and the heads of several laboratories got together.

"Today I am announcing two things." As the commander of the Chaldeans, Su Yuntian stared at everyone and said, "First, from today onwards, the first branch of the technical class, the explosives laboratory, will be independent, and the explosives research institute will be established, and it will be moved out of the city, away from the downtown area. At the same time, the level of the explosives research institute was raised by half a level, and it was directly under the jurisdiction of the chief engineer Lou Gao. ”

When everyone heard this, they took a few seconds to think.

As the head of the explosives laboratory, Sidi was the first to react.

…… The meaning of the commander is to promote himself!

"The second thing is to congratulate us on the breakthrough in explosives research and entering a whole new field, which is the result of everyone's joint efforts."

Su Yuntian didn't pause for too long, and began to take the lead in applauding.

"Today's explosion, although it is only a small step forward for the Chaldees, is a big step in the historical process of the Douluo Continent!"
