The big river is choppy, and the big boat is moving smoothly on the river, and the black river water hits the bow of the boat head-on, making a noisy sound, throwing small splashes of water into the night sky.

In one of the cabins, there was not the slightest shaking.

Ye Changsheng's silver-haired shawl sat on a futon carved from a red spar, and from his bluff right palm, there was a hair-like line of fire, slowly extending out.

As soon as that line of fire drilled out of his palm, the temperature of the entire room suddenly rose a lot, and the spar futon under Ye Changsheng's body also emitted a brilliant light.

The line of fire stretched forward like a fluttering string, and when it extended three feet away, it came to a standstill.

Airplanes!

The line of fire trembled, and with a thud, it burrowed back into Ye Changsheng's palm.

Ye Changsheng's eyes were raised, and a smile appeared on the corner of his mouth: "Yes, there has been progress again!"

Coo, coo, coo!

In the spiritual sea space, the small flame jumped for a moment, and then the sound of a rabbit full of smugness echoed in Ye Changsheng's mind.

Ye Changsheng smiled dumbly, although under his tutelage, the cooperation of the son and mother spiritual fire became more and more tacit, but it was still early before the real success.

After the heat flow in his body completely dissipated, Ye Changsheng sent out a thought towards the spiritual fire of the son and mother: "Goo, let's do another experiment, you converge the energy, when it extends out of my palm, let the energy burst out, can you do it?"

The spiritual fire of the child and mother was silent for a moment, and then let out a cooing sound again.

Ye Changsheng couldn't help but be overjoyed, gathered his mind, and slowly started the allogeneic cycle.

In the spiritual fire of the son and mother, a hair-like line of fire, Shi Shiran extended out of the spiritual sea space, spreading freely in Ye Changsheng's body.

Both stability and efficiency have been enhanced a lot compared to before.

Soon, this line of fire drilled into the shoulder, spread rapidly along the arm, and unhindered, drilled out of the palm of the hand.

This is the time.

Ye Changsheng deflected his palm in the direction and said softly: "Let's go!"

Call!

The line of fire sped up and flew forward, burrowing into the crack of a black boulder.

To Ye Changsheng's disappointment, the boulder was neither exploded nor burned red, but the line of fire drilled into the cracks, but it burned like a wick.

After all, the control of the Zimu Spiritual Fire over its own energy was a little worse, and it was impossible to break out suddenly.

The line of fire remained in its original state, burning only smoothly and subtly.

Ye Changsheng estimated that there was no day and night, and the line of fire in the crack of the stone would not be extinguished.

With a move of his mind, the Flame Rabbit drilled out of his body, his spirit was sluggish, and he looked at Ye Changsheng with some embarrassment.

Ye Changsheng smiled disappreciatively, took out more than a dozen spars, and fed them to the Flame Rabbit Gugu.

When Gugu was full, Ye Changsheng took out another half-human-high Xuaniron stone and placed it in front of him.

He pointed to the stone and encouraged, "Goo, you try it now, harness the energy, extend towards the gap in the stone, and when the line of fire drills into the stone, then detonate the energy." ”

Looking at the stone with fiery eyes, he also followed Ye Changsheng's example, raised his right palm, and sent a line of fire from his palm.

It's not like it's in Ye Changsheng's body, Gugu is always afraid of hurting Ye Changsheng, so he can't let go of his hands and feet.

But now that it has no such scruples, it is just purely controlling energy, and it is naturally much more handy.

But even so, Goo Goo didn't want to fail again, so the firing line that was sent out stretched very slowly, and was always restrained by Googo's powerful thoughts.

The line of fire continued to stretch forward, getting closer and closer to the gap in the stone, and Goo Goo became more and more nervous.

When the line of fire drilled into the cracked stone crevice with precision and reached the end, Goo Goo slammed into it, instantly injecting powerful energy into it.

"Boom!"

The line of fire erupted suddenly, and the entire piece of dark iron stone was enveloped in flames in an instant, and the impurities were vaporized at a speed visible to the naked eye, and the molten iron fell to the ground with a clatter.

Ye Changsheng was shocked, the melting point of the dark iron reached more than five thousand degrees, and even if it was placed in the No. 1 furnace of the Wenjian Hall, it would take three days and three nights to melt.

However, Goo just released a line of fire, and it melted the Darkiron Stone in an instant!

Before the floor was burned through, Ye Changsheng hurriedly summoned the cold qi of the ice attribute and solidified the molten iron.

"Goo, you did a good job this time, let's have another one more difficult!" Ye Changsheng looked at the Flame Rabbit and said encouragingly.

Coo, coo, coo!

The Flame Rabbit's eyes were full of excitement and he nodded vigorously.

For itself, being able to harness energy with ease is a good thing, not to mention, Gollum feels like it's a game, which is fun.

According to Ye Changsheng's instructions, the palm of the Flame Rabbit sent out a line of fire again, and when the line of fire drilled into the crack in the stone, it suddenly detonated.

This time, though, the line of fire didn't completely burst, leaving at least a foot behind on Gollum's palm.

"That's it!" Ye Changsheng was overjoyed, quickly extinguished the fire, and took out a stone from the demon space.

These stones were some of the sword-forging materials he had stockpiled, and they were also used for research on the road, but it was obviously more important than training the spiritual fire of the son and mother.

The next five tests were all incomplete detonation, but the line of fire remaining in the palm of Googu's palm was getting shorter and shorter.

By the fifth time, the length of the remaining line of fire had been shortened to three inches.

It's not the point to shorten it, it's just to arouse Gollum's interest and fighting spirit, and in essence, it's the key to let Gollum grasp the timing of detonating the line of fire.

Obviously, after six tests, Goo Goo has been able to control the timing of the detonation, otherwise it would not be possible to control the length of the remaining line of fire so finely.

This is probably the wisdom and spirituality that the creation of heaven and earth has given it.

Ye Changsheng took out more than thirty fire-attribute crystals, so that the tired enough to choke on Gugu had a full meal, and he also made an exception to feed Gugu a fire-attribute crystal egg, and the beautiful Gugu cooed and screamed.

One person and one rabbit adjusted to the best state, and Ye Changsheng took Gugu into his body.

After sitting cross-legged for a while, Ye Changsheng's mind calmed down, and he sent out a thought towards the spiritual fire of the son and mother: "Goo, let's start!"

Airplanes!

The small flames in the Linghai space jumped a little, and a line of fire spread out.

The line of fire drilled out of Ye Changsheng's palm smoothly and stretched forward.

When the line of fire drilled into the crack of the stone, Ye Changsheng raised his eyes: "Release!"

"Boom!"

The stones were suddenly enveloped in flames and burst into flames.

And outside Ye Changsheng's palm, it is neither long nor short, and there is still an inch-long line of fire remaining.

It worked, haha!

Ye Changsheng didn't care about the palm that was burned, stood up suddenly, and laughed.
