Chapter 18 The Powerful Palm Cannon

Fortunately, this was a dream. If it had been the first test in reality, there would probably have been serious problems.

Nasita stretched out her hand and gently tapped with her index finger.

A green bubble enveloped Chen Bo, and then slowly released him.

And Chen Bo's body was restored with a single click.

Dreams are wonderful.

Nasita is a deity who controls dreams. Even the elite soldiers who are close to the deity can not detect anything unusual in her dreams, even after repeating them hundreds of times.

Because Nasita's dreams are 100% simulations, the dream world is no different from reality.

With the blessing of this dream power, Chen Bo essentially possessed a testing ground similar to a simulated universe.

While not everything can be tested, it's certainly sufficient for now.

"It seems your physical abilities aren't quite up to par with the weapon's power," Nasita said, approaching Chen Bo. "So, how should we adjust it?"

Naxida is a guiding teacher.

Chen Bo had already figured out the problem.

Mark 42 is a full-body suit of armor, where the force is evenly distributed across the entire suit. He has only completed one palm-sized cannon module, so all the recoil must be absorbed by his two ordinary arms.

Simply put, if you are only using a single module, it is best to reasonably reduce the output capacity.

The specific power levels still need to be refined in the design.

"Let's try the attack mode again, and then I'll think of a solution," Chen Bo said.

The hand cannon has two modes: one is the power mode, where grass elemental energy is evenly ignited in the combustion chamber.

Another mode is the attack mode. During the charging phase, the grass elemental energy will be ejected in a vortex, condensing into a grass elemental ball in the palm of the hand, and then igniting it.

The bursting Grass elemental energy will push the central Grass sphere outwards and ignite it.

It explodes upon hitting the target.

Nasita readily conjured three large trees, which appeared about thirty meters in front of Chen Bo.

The tree is ten meters tall and one meter in diameter.

It seems that hitting accurately is very easy.

Chen Bo adjusted his posture, turned to the side, squatted slightly into a horse stance, and supported his right wrist with his left hand, guiding the recoil to his whole body.

He stared at the stone target in the distance, his five fingers loosely clenched.

This time, Chen Bo only slightly gathered his strength.

The palm cannon had just started to hum when the fire and grass elements reacted violently in the small combustion chamber, and Chen Bo released it.

"Fire!"

Chen Bo suddenly spread his five fingers.

A swirling ball of grass elemental energy, enveloped in flames, was launched.

When it hit the tree, the grass element exploded and was then ignited by the fire element, creating an airburst similar to a dust explosion.

At the same time, Chen Bo was also pushed back a step by the recoil.

This was the least powerful attack.

Chen Bo felt that the recoil was probably equivalent to that of a Barrett.

According to the design, the maximum power is about thirty times that of this attack, but it requires three seconds to charge up.

Chen Bo walked up to the tree and found that a small crater about ten centimeters in diameter had been blown open on the tree, and fire element was attached to it, still burning fiercely.

The surrounding ground was also on fire, and it looks like it won't be extinguished anytime soon.

This power is roughly equivalent to that of a hand grenade.

"Not bad." Nasita walked up to the tree and observed it carefully. "This kind of attack is enough to deal with weak monsters."

Chen Bo nodded in agreement: "Once it's made, I'll have some ability to protect myself."

"However, before redesigning, I also need to test the maximum power of the palm cannon. Nasita, you help me."

"Okay." Nasita nodded and floated behind Chen Bo.

Chen Bo took a deep breath and raised his right arm.

The internal structure of the palm cannon began to operate at high speed, and the grass elemental power was continuously drawn out, compressed, and filled into the micro combustion chamber, condensing into a dense grass elemental sphere.

Three seconds to charge up.

This is the current design limit.

It will automatically launch if it takes more than three seconds.

Subsequently, the free grass element in the combustion chamber was ignited, igniting the grass element ball and spraying it out.

The enormous fireball crashed into a tree thirty meters away.

boom!

A huge fireball rose up.

When the flames died down, the tree trunk, which was one meter in diameter, looked as if it had been bitten.

A large part is missing.

One more shot and this tree will fall.

What follows is a terrifying recoil.

The powerful reaction force twisted Chen Bo's arm and sent him flying.

Naxida, who was standing behind Chen Bo, gently flew up and caught him.

With a gentle touch of his finger, Chen Bo's shoulder was instantly restored.

"A weapon of this power is too much of a burden for you at your current level," Nasita said.

Chen Bo shook his arm, which had returned to normal, and said with a wry smile, "Indeed, this is the drawback of only making single modules. Without the support of full-body armor, the body really can't withstand it."

He looked down at Nasita and found that the goddess of wisdom was staring at him with wide eyes, her gaze full of curiosity.

Chen Bo was also drawn to Naxida's eyes and couldn't help but stare at them intently.

Nasita's face flushed slightly, and she muttered softly, "Don't stare at me like that, I get shy too."

"Haha, don't laugh at the challenge, I lost." Chen Bo couldn't help but laugh out loud.

Nasita was stunned, tilting her head as she asked, "So this is some kind of challenge?"

"I guess so, it's a little game that can improve your mood."

Chen Bo made a simple joke, and then got back into work mode.

He pulled out the virtual model of the palm cannon, disassembled it into hundreds of parts, suspended them in mid-air, and then began to adjust them.

"The adjustment method is too crude; it needs to be refined."

Chen Bo continuously modified the structure of the parts.

With this modification, Chen Bo plans to preset five output levels for the Palm Cannon, each of which can be further finely adjusted.

Furthermore, a reverse propulsion system has been added.

He added sixteen micro-nozzles to the side of the forearm armor.

When the palm cannon fires, these nozzles simultaneously eject streams of fire elemental energy, generating forward thrust to counteract the backward recoil.

"One more time."

In this way, even with only one part, it can be launched with maximum power.

After the adjustments were completed, Nasita helped Chen Bo reassemble the device and fastened it to his arm.

After that, Chen Bo began practicing flying through the nozzles in his palms.

This is a stumbling but progressive process.

After fine-tuning the gears, Chen Bo no longer needs to worry about mistakes causing excessive thrust.

At first, he was like a duck that had just learned to walk, staggered around by the airflow from his hands, and even fell headfirst into Nasita's arms.

Nasida sat on the swing beside him, watching Chen Bo perform "freestyle wrestling" in the air, and the corners of her mouth unconsciously turned up.

After more than an hour of practice, Chen Bo gradually mastered the skills of flying.

He opened his arms, palms down.

Two steady pillars of red fire erupted, slowly lifting his body up.

"It's a success!"
