"The metal laboratory is an exclusive building of my castle."

"It can increase the attack and defense of the troops by 10%. It can help me analyze various alloys and provide a technical basis for building equipment."

“It’s very powerful!”

"However, the metal laboratory also has limitations. Currently it can only analyze metal alloys. If it can conduct research on other materials, such as nanomaterials, then the evolution of my armor can also be put on the agenda!"

"So, do you want to use this blueprint to upgrade Metal Laboratory 2?"

Tang Xiaofan frowned, thinking whether it was more cost-effective to upgrade the farmer's factory and save 20,000 soul stones, or whether it was more cost-effective to upgrade the industrial metal laboratory.

After pondering for a long time, Tang Xiaofan finally made a decision.

"The castle building upgrade blueprint is marked as rare, so it is obviously difficult to find out."

"And Metal Labs,"

"Another camp-exclusive building that cannot be upgraded with materials."

"Upgrading the farmer's factory can only save some soul stones at most. In comparison, upgrading the metal laboratory seems to be more cost-effective."

"After all, who knew that it would take such a long time for such a drawing to come out again?"

"In comparison, it is much easier to obtain soul stones!"

Thinking of this,

Tang Xiaofan turned to the metal laboratory and without hesitation, immediately chose to use the drawings.

In an instant, the drawing in his hand disappeared.

The metal laboratory in front of him was shrouded in a dazzling golden light.

You can vaguely see that the appearance of the metal laboratory building is changing, but you can't see it clearly.

After about a few minutes,

The golden light dissipated, and the upgraded metal laboratory appeared in Tang Xiaofan's field of vision.

Compared with before the upgrade, it is more magnificent, majestic and spectacular, and the golden light it emits is more intense and pure.

【Materials Laboratory】

[Description, the ultimate exclusive building of the farmer family, the ultimate laboratory of materials, which can produce and analyze all substances. 】

[Effect 1: Greatly improve the loyalty of castle residents to the castle lord]

[Effect 2: Increase the attack power and defense power of all castle troops by 20%,]

[Effect 3: Can analyze and provide relevant formulas for materials that can be described]

[Hidden effect 1: As the ultimate exclusive building of the farmer family, the material laboratory can greatly increase the friendship value of intelligent creatures of the light system, and greatly increase the probability of intelligent creatures of the light system taking the initiative to seek refuge! 】

[Hidden effect 2: Greatly increase the hatred value of the dark and evil camp! 】

[Hidden effect 3: Once the material formula developed in the laboratory is applied, it can be synthesized using materials in the current world]

"Materials Laboratory!"

"After the upgrade, even the name is different! Looking at the information attributes of the materials laboratory, Tang Xiaofan took a breath.

Before the upgrade, the Metal Laboratory had only three normal effects, plus two hidden effects.

After the upgrade, the material laboratory has three normal effects and three hidden effects.

It seems that all the effects are to increase the bat speed.

The attack and defense of the castle troops have also been increased from the previous 10% increase to 20% increase.

Just for this reason, it was worthwhile for Tang Xiaofan to choose to use the blueprints to upgrade the metal laboratory, "In addition."

"The study of materials is based on the analysis of materials currently existing in the world,"

"Otherwise, if we research out materials that can be produced using materials that are not available in the Gods and Demons Continent,"

"Isn't there no chance of mass production?"

"That is to say,"

"In the future, even if it is a new material developed in the materials laboratory, I can find a way to mass-produce it!"

"And, after the upgrade,"

"The research speed of the materials laboratory will also be greatly improved, and the work efficiency will be greatly improved."

"It's simply too strong!"

Tang Xiaofan couldn't help being happy.

He was glad that he didn't use the blueprints to upgrade the workers' and farmers' factory.

The value of those soul stones saved is simply not comparable to the new properties of the materials laboratory.

He made a lot of money! After a while, Tang Xiaofan calmed down.

He looked at the little angels kneeling at the door of the materials laboratory and praying.

These troops of the light camp were inspired by the materials laboratory.

They spontaneously knelt down and prayed at the gate of the temple; the little angels were also very excited after appearing in the materials laboratory, but in the end they chose to perform daily prayers near the farmer's factory.

"What a terrifying atmosphere of faith!"

In the distance, the girl Olivia, the great elf Monica and the elf elder Becky all showed surprised expressions.

"Materials Lab!"

"Mother, what is that?"

Faced with Monica’s inquiry,

The girl Olivia's expression was dull, as if she was lost in memories

"That is the supreme palace of the farmer clan. It once appeared in ancient times and is the core temple of the farmer god system!"

"But since the end of the ancient god war, the materials laboratory has been turned into ruins. It is said that the Dimension Demon God personally demolished it!"

"Today, maybe even the remains of the ruins can't be found,"

"Didn't expect that,"

The girl Olivia said with great horror, "It actually came to the lord's castle! Could it be said that the lord will become a god in the future?"

"god?"

The big elves Monica and Becky were trembling.

far away,

Tang Xiaofan heard the discussion of the three elves.

He couldn't help but shook his head.

He doesn't want to be a god,

His title is much more powerful than God.

This time.

A warrior came over, knelt down respectfully and said, "My almighty lord, I still have a batch of materials that I can handle."

Tang Xiaofan glanced at the giant dragon corpses piled up in the open space in the distance.

There are twenty-three in total.

"Go rest and let others handle it!"

"As you command, Almighty Lord!"

The soldiers quickly retreated and went to the city to rest.

Tang Xiaofan asked Nong Yi and others to store all the dragon corpses in the castle warehouse.

The reason why he didn't let the soldiers collect it was because after collecting it, they could only get some dragon materials at most.

In comparison, the seemingly complete dragon body was more valuable. He had to save it and sell it to the sponsor for a good price.

After putting away the dragon corpse,

Tang Xiaofan turned his attention to the dark gold treasure chest about two meters long in front of him.

【Treasure Box】

[Grade: Dark Gold]

[Description: Open it and you will have unexpected gains]

"An unexpected gain?"

Tang Xiaofan was very interested and immediately opened the treasure box: the moment he opened the box, a dazzling red light burst out, almost blinding Tang Xiaofan.

He looked at the items in the box and looked like,

Is it a dragon egg? Its maximum diameter is more than one meter and it is oval in shape.

The whole body is red, emitting red light, like a rare giant ruby.

The shell of the dragon egg is also densely covered with golden lines to show its nobility.

[Dragon Egg of the Flame Dragon]

【Demigod level】

[Incubation time: three days]

[The growth potential is extremely high, and he has the potential to become the dragon king of the flame dragon clan. Cultivate it well and it will become the most powerful Flame Dragon King under your command!】
