On the path of Mohism, Chen Yu is not only the pioneer, but also the person with the highest attainments and the deepest cultivation today.

Although he did not dismantle Gu Chen's puppet in detail, Chen Yu still vaguely sensed a somewhat dangerous aura.

The danger does not refer to the possibility of endangering others, but to Gu Chen's next experiment.

Gu Chen needs to use himself as the subject of first-hand testing.

“It’s the best choice for me to do it myself, so I can gain first-hand experience.”

Gu Chen smiled at Chen Yu, Ma Kun and others.

Then, he held the puppet and pointed the tip of the puppet's feet at the position of his heart.

The sharp thorn like an awl was pressed against his chest.

Everyone in the surrounding Tiangong Palace looked horrified.

But Gu Chen was obviously not being polite to them.

As if committing suicide, he had pierced the puppet into his own heart.

In the Daming Palace, Zhang Dongyun watched this scene with great interest.

Someone in the Tiangong Hall shouted: "Are you crazy?"

But he saw that Gu Chen seemed not to feel the pain of his heart being pierced. Instead, he looked relaxed and smiled slightly: "How could it be?"

Then, everyone watched the puppet disappear from his chest, as if it was completely buried inside his body.

The next moment, Gu Chen's flesh and blood body began to gradually change.

Its body shape also began to swell and become larger.

However, instead of swelling of flesh and blood, its body surface took on a cold and hard appearance, and it finally seemed to turn into a giant doll over three meters tall, with a metallic luster shining all over its body.

Zhang Dongyun's cultivation strength and eyesight are now far beyond ordinary people.

Without the help of the Invincible City system, he could also see that the heart position in Gu Chen's body was crystallized, and a stream of spiritual energy was continuously generated from it, supplying his whole body and causing his body to continuously change.

The giant doll transformed by Gu Chen continued to grow in size, eventually reaching a height of over six meters, standing upright in the Tiangong Hall, like a steel giant.

The facial features of the doll do not have the characteristics of Gu Chen himself, but are blurred.

It looks like the puppet he stabbed into his body has been enlarged many times in proportion, but the current steel puppet no longer has those sharp cones under its feet.

Everyone in Tiangong Hall looked at Gu Chen in shock: "You...are you okay?"

"A little better than I expected."

The steel doll did not speak, but Gu Chen's voice came from its chest and abdomen.

Ma Kun frowned: "It's not that you are inside this steel doll, but only your soul is still inside?"

Gu Chen replied: "Strictly speaking, we don't differentiate between each other."

Ma Kun took a deep breath: "So you mean, you have become like this?"

Although this seems to be the case from the visual effects just now, such a change, for Ma Kun, no matter how you look at it, it is a demonic practice, not a Mohist organization.

"Can you return to your original state at any time?" Chen Yu asked at this time.

Gu Chen replied: "According to expectations, it should be yes, but before that, I will test other things first."

After saying that, the huge steel puppet immediately moved its limbs on the spot.

His movements look a bit stiff and clumsy, not like a real person.

But with just a few casual gestures, onlookers can feel the power and gravity.

The steel puppet is extremely tall, so the space inside the Tiangong Hall is also huge, allowing him to move freely.

Gu Chen, who had turned into a steel puppet, jumped forward.

Although the movements look rigid, the speed and distance of his straight-line leap are extremely astonishing.

Compared to its huge body, its speed can be said to be incredibly fast.

Chen Yu, Ma Kun and others looked at each other.

"It's hard to compare with people, but compared to some large demon clans, this kind of leap is at least the demon king realm, starting to attract starlight, right?" Someone said, his tone was not very sure.

Chen Yuyan said: "The strength is not bad either."

Everyone had different expressions, but most of them frowned.

Gu Chen himself, regardless of his Mohist attainments, based on his original demonic cultivation, was only at the level of the fifth realm.

But after he transformed into a steel puppet, he saw that no human warrior or great demon in the tenth realm might be able to match his physique.

Taking into account the materials used by Gu Chen to create the puppet, if the value is fully reflected, then the physical strength of this puppet is probably higher than that of many human Martial Emperors and demon emperors.

and……

"According to those raw materials, it should be more than just shaping the body."

Before Chen Yu finished speaking, he saw the steel puppet suddenly raising his hand.

In the palm of his hand, there was purple brilliance surging.

The next moment, a ray of purple light flew out from afar and hit the target specially used for testing weapons in the Tiangong Hall.

Gu Chen's aim was obviously not very good. The purple light did not hit the center of the target, but fell off.

But the target suddenly shook violently as a whole, and the edges cracked on the spot.

"How much purple silver and iron did this kid add?" Ma Kun cursed angrily: "You don't know how expensive firewood and rice are if you don't live in the family!"

Someone whispered softly: "If he adds some treasures that contain the secrets of the void, will this big guy be able to break through the void and act like a real Martial Emperor or Demon Emperor?"

When everyone heard this, they all frowned slightly: "I'm afraid it's really hard to say..."

While everyone was discussing, Gu Chen was also practicing in all aspects.

Until, the steel puppet's movements gradually slowed down.

"Is this the limit?"

Gu Chen's dissatisfied voice came from the steel puppet's body.

He stopped quickly, then suddenly raised his palm and cut his other arm with purple light.

When everyone saw this, they were all shocked: "What are you doing?"

"Don't worry, you won't feel pain." Gu Chen replied: "This is exactly one of the advantages of the doll as I expected."

The defense of the steel puppet is indeed extremely high. It took a while to cut with its own purple light, but it took a while to remove one of its arms.

And with the massive consumption caused by the purple light, this huge steel puppet finally came to a complete standstill and became silent.

"The spiritual energy is consumed very quickly."

Everyone in the Tiangong Hall was talking about it:

"What did you end up cutting off your own arm for?"

"It doesn't look like it's just testing attack and defense."

"With so many rare and precious materials, has all the spiritual energy been completely exhausted?"

"It doesn't feel like it. It should be a temporary silence. I feel that the doll contains the Five Elements Transformation Formation. After a period of recuperation, it can be restored again."

They gradually became immersed in academic research and discussed happily.

In the Daming Palace, a certain city lord named Zhang was a bit dumbfounded.

...Compared with the current world, Gu Chen's style of painting is a bit crooked no matter how you look at it.

Although Chen Yu and the others have made some inventions and their painting style is not very correct, Gu Chen's is really a bit outrageous.

Moreover, there are still many problems in his research.

In the Tiangong Hall, Chen Yu and others also noticed something was wrong.

After the steel puppet became silent, no other changes were seen.

And Gu Chen himself never showed up.

"He...he can't change, can he?" Ma Kun was horrified.

Chen Yu frowned and moved to the side to look up and down carefully.

Chen Yu had an ominous premonition when she saw that Gu Chen was holding a doll with sharp vertebrae extending from its feet.

When he saw Gu Chen stabbing the sharp cone into his chest, he became even more uneasy.

Fortunately, Gu Chen didn't seem to be dead afterward.

But now, you need to face another problem.

The other party may not be able to change back to the same person...

Chen Yu looked up at the sky, and after thinking for a long time, he turned to say: "Cry the frost from the sky."

When Ma Kun heard this, he immediately went to get it without saying anything.
