Time passed quickly in the experiment, and more and more data was recorded in Yu Cang's hands.

The epic high-level summoning consumed a lot of Gu Jieshuang, but after several experiments, although Gu Jieshuang was no longer empty, his expression was still very firm.

This is to witness the birth of a way of summoning, who would be tired of it?

Besides, being able to stare at Yu Cang, who is working seriously, so closely and openly, her heart is already very satisfied.

When she was in the card making room, she could only occasionally sneak a peek behind the door, how could she be so enjoyable now!

Yu Cang didn't care about Gu Jieshuang's gaze, now he just looked at the data in the computer, his brows furrowed.

There should be some kind of relationship between the Ice Heart Sword and the materials needed.

It seems that there is some kind of value in each of these equipment cards, and as long as the sum of the values of the summoning materials is equal to the value of the Ice Heart Sword, then it can be successfully summoned.

It's just that this value is not written in the soul card data, and there is no relevant research in Yu Cang's memory.

At first, Yu Cang thought that this value should be soul energy consumption, but after comparing several sets of data, he found that soul energy consumption could not strictly conform to the law, because the soul energy consumed by Gu Jieshuang summoning all the summoning materials at the same time was much less than directly summoning the Ice Heart Sword!

This discovery undoubtedly means that this new way of summoning has great potential.

"This form of expression is a bit like a cohomonic call...... However, soul cards do not have star ratings, nor do they have similar attributes...... Do you want me to create an attribute out of thin air? ”

Yu Cang tapped the writing pen with one hand, and the thoughtful look on his face became more and more intense.

"It seems that this is the only way to go...... There should be a certain connection between this attribute and soul energy consumption, and it can be seen from the trend of these sets of data, as long as a few more sets of experiments are done, it should be able to be summarized into a formula. ”

Yu Cang looked at the computer while writing and drawing in the notebook at hand, and said directly in his mouth: "Defrost, continue." This time, try it with the Frost White Sword, the Iron Sword of the Brave, the Sharp Spear, and the Bone Hammer. ”

"Okay." Gu Jieshuang took a deep breath and took out four equipment cards.

This time, the three equipment cards used as materials are all very basic ordinary quality, and they belong to the kind of equipment cards that even the first- and second-level soul card masters are a little disdainful.

I guess it will fail......

Gu Xie Shuang silently guessed in his heart.

After all, according to common sense, the quality of the sacrifice also has a lot to do with the success of the summoning from above.

But to her surprise, as several green rings flashed out of thin air, these pieces of equipment were directly integrated into the Ice Heart Sword!

"This ......" Gu Jieshuang's eyes widened slightly.

How could it be, obviously the three rare ones failed when they were used as materials...... Changed to a regular card, but it succeeded?

How is this done?

"How did you do that?"

Gu Xie Shuang was stunned.

How can someone say what is on their mind?

When I looked back, I found that Lin Yunqing didn't know when she was standing on the edge of the test site, her brows were slightly furrowed, and her eyes were full of doubts when she looked here.

"Huh?" Yu Cang raised his head, "Which part?" ”

"Soul energy is consumed." Lin Yunqing approached, his eyes swept over the data of the computer, "The soul energy consumption of the four equipment cards used as sacrifices adds up to nothing compared to the consumption of directly summoning the Ice Heart Sword, how can this be done?" ”

Lin Yunqing's heart has already set off turbulent waves.

The scene in front of her directly broke her cognition!

You must know that although the upper-level summoning can allow the soul card master to launch a higher-quality soul card by leapfrogging, on the whole, the vast majority of upper-level summoning is a loss of soul energy!

This has almost become a piece of common sense, but the scene that is happening in front of you is obviously contrary to this common sense!

"It's normal." Yu Cang's face was calm, "You may not have finished your research, if you eat that 'fusion of darkness and wood' thoroughly, you will find that the fusion summoning will also save soul energy to a certain extent." ”

"This ......" Lin Yunqing's face kept changing.

Isn't that scientific......

No matter how powerful you are, you must always abide by the law of conservation of soul energy, right?

If Fusion Summoning is more cost-effective than Direct Summoning...... So what's the deal with the other decks? Doesn't that mean that all decks will have to be fused in the future?

Suddenly, Lin Yunqing realized something: "Wait, what do you mean...... Is the experiment you're doing now a new way of summoning? ”

"Yes." Yu Cang nodded, "Defrost, continue the experiment, this time only use the frost white sword and dragon tooth knife." ”

"Roger!" Gu Jieshuang's face was calm, and then he did as he said.

It's just that, contrary to her expression, she is secretly happy in her heart!

Look, what a shameful expression this is.

She has to admit that Lin Yunqing's appearance of never seeing the world makes her happy!

Although when she first started the experiment this afternoon, her expression was no different from Lin Yunqing......

But at least now, I have a stiff expression!

Gu Jieshuang is not a person who cares about this kind of thing, but after all, this Lin Yunqing can now be regarded as his "rival in love", he is accustomed to all kinds of magic in Yu Cang, but Lin Yunqing is shocked, isn't this contrast enough to make people happy?

Strange comparisons are about to rise!

Thinking like this, Gu Jieshuang skillfully completed the summoning of the Ice Heart Sword again, and ignored the faint stinging pain of soul energy depletion in his mind, and his expression was always light.

And Lin Yunqing didn't think about it so much, and he didn't hide the meaning of his expression, and he was shocked very simply.

"The soul energy consumption this time is still very low...... How the hell did you do it? ”

Yu Cang's eyes did not move, still on the computer: "If you are interested, I can teach you later, now, look first." ”

Lin Yunqing's lips moved, as if she wanted to ask something, but seeing that Yu Cang's brows had wrinkled slightly, she still closed her mouth with interest.

Seeing this, Gu Jieshuang's heart became even happier.

And voila! Annoying!

Enlightenment, how can you compete with me like this!

"Defrost, cancel summoning, next set is ......"

"Roger." Gu Jieshuang responded neither humbly nor arrogantly.

……

Yelai lay on Cang's shoulder, looking at the scene in front of him, the corners of his mouth seemed to raise imperceptibly.

The slender tail kept brushing from Yu Cang's back, and he put his little head near Yu Cang's collarbone at night and took a quiet nap.

……

"It's hard work, let's get here here today." Yu Cang breathed a sigh of relief, raised his head and smiled at Gu Jieshuang.

"It's okay, I can continue."

"I know you're good, but let's take a break." Yu Cang's tone was a little admiring, "It's worthy of you...... After an afternoon of non-stop summoning, I can still keep my face unchanged, and if I were replaced, I guess I would have fallen to the ground tired. ”

"Hehe......" Gu Xie Shuang showed a just right smile.

Tired, of course tired, very tired, very tired!

It's just a mediocre expression management.
