Tuguhun adjusted the speed gear several times, and the speed of the "Iron Bird" quickly soared to 500 kilometers per hour, and on the "Huangquan Road", he and the car turned into an afterimage, and the roar of the "Iron Bird" engine was deafening.

The spitting bones covered with armor are almost unaffected by the external environment, with clear vision and keen hearing, and everything is as usual.

A small black dot suddenly broke into his field of vision, it was an armed transport vehicle, and on the front windshield of the "Iron Bird", a red ring cross-shaped aiming star had firmly locked the small black dot that was getting bigger and bigger.

"Boom, boom, boom—"

"Poof, poof!"

The 11 barrels of the "Super Gatling" automatic cannon of the armed transport vehicle rotated wildly, and the 30-millimeter caliber bullets fired formed an airtight barrage, like a pouring rain head-on towards the "iron bird" carrying the vomiting bones.

"Ding-dong!

A dense barrage of bullets poured down on the shell armor and bulletproof glass of the "Iron Bird", splashing sparks of nearly large flowers.

The "Iron Bird", which had strengthened its armored defenses, was safe and sound and continued to advance.

"Fire!" Tu Gu looked at the right time, and gently pressed the firing pedal of the sixty-millimeter caliber gun with the tip of his right foot.

"Knock poof!"

Tu Guhun finally realized the feeling of "a small car carrying a cannon" - the whole locomotive slammed down, and a cannon shot out as soon as it started, accurately hitting the tail of the armed transport vehicle.

"Boom!"

With a loud bang, the armed transport vehicle was instantly enveloped by a cloud of red and black fireworks, and the rear of the vehicle was blown to pieces, and the strong air wave caused by the explosion threw half of the armed transport vehicle into the sky.

The huge recoil of the main gun almost overturned the "Iron Bird", and it took a lot of effort to stabilize the body, and then it passed under the half-section of the wreckage of the armed transport vehicle that had been blown up into the sky, and then all kinds of wreckage fell down the road behind it and burned violently.

"Well done!"

The "Iron Bird" is equipped with high-definition cameras on the body, and the video of the exchange of fire between the two sides has been broadcast live to Prince Hao Lian and scientific researchers in the backfield.

"Go on!" the prince's voice came from the communication system.

Tuguhun drove forward and continued to drive forward, and soon, a moving behemoth appeared in his field of vision, which was none other than the "Dragon Nine" Type A Marine Mecha.

"Boom!"

A 150-millimeter shell burst through the air and exploded not far behind the "Iron Bird." A strong wave of air swept the "Iron Bird" to the ground, knocking it out and throwing it down.

After desperately stabilizing the locomotive, the locomotive's sighting device had locked onto the "Dragon Nine" Type A land mecha.

"Launch!"

Tu Guhun knew that the second wave of artillery shells fired by the "Dragon Nine" was coming immediately, and the fighter plane was fleeting, so he resolutely pressed the missile launch button and launched all six missiles, and at the same time continuously stepped on the main gun launch pedal to shoot out all the remaining five 60-millimeter kinetic energy shells.

"Boom, boom, boom......"

Six missiles and five artillery shells hit the "Longjiu" Type A Marine Mecha in succession, and the fire enveloped the Marine Mecha, while at the same time, two 150-millimeter shells exploded on the muddy ground in front of the "Iron Horse," and a powerful wave of air lifted the "Iron Horse" and Tu Gu into the air.

"Buzz!"

Tu Gu felt that his whole body senses were stagnant, his brain was dizzy, and then he fell heavily more than ten meters away.

"Stop the attack! Go and save people!" In the communication system, Prince Hao Lian shouted loudly.

The rescue team heard the noise.

It's just that Tu Gu Xun can't take into account any movement in the outside world, and all his attention has been focused on the small universe in his body.

At the moment when the two shells shot into the ground and exploded, the small universe that had not broken through for a long time finally moved.

The long-tailed comet formed by the fire dragon's vitality and slowly orbiting the blue sphere seemed to sense a huge crisis imminent, and exploded instantly with a "poof", turning back into the previous form of the fire dragon's vitality, and plunged headlong into the sea of vitality.

"What?!" Vipassana vomited in amazement.

"Boom!"

A dragon enters the sea, stirring up the monstrous waves of the sea of vitality, and then triggers the resonance of heaven and earth, and the stars change.

When Tu Gu Hun was still stunned, he sensed that there was an undercurrent surging under the sea of qi, and the source of that surge was the fire dragon vitality that had rushed into the sea earlier, and it seemed to have made a new discovery in the bottomless abyss of the sea of vitality.

The bottomless abyss of the Sea of Vitality, Tu Gu Hun had already been aware of it in the early stage of the formation of the small universe, but at that time, he was focused on consolidating the realm and did not be too distracted to explore the truth.

After the realm was consolidated, Tuguhun tried to explore it many times, but found that the bottomless abyss was like a forbidden area.

Unexpectedly, the fire dragon broke in with a sullen head, and now he actually got a glimpse.

He found that the fire dragon vitality was shuttling between the countless spheres suspended in the bottomless abyss, seemingly aimless, but it seemed to have rules to follow.

Suddenly, the fire dragon's vitality opened its mouth to devour a black sphere, and then quickly floated upward.

The bottomless abyss rumbled without a black orb, and the position of the remaining black orbs suspended within it had all changed.

"Whew!"

The fire dragon vitality rushed out from the sea of vitality until near the blue sphere, it opened its mouth and spit out, the black sphere was spit out, suspended near the blue sphere, and then the fire dragon vitality slammed its head lightly, knocking the black sphere that was a few sizes smaller than the blue sphere into a certain track near the blue sphere, and after the black sphere entered the orbit, it actually slowly ran around the blue sphere.

"This is ......" Tuguhun stared at the two spheres, one blue and one black, very familiar.

"If the blue sphere represents the Earth, does the black sphere orbiting the blue sphere represent the Moon?" Tu Guhun remembered a term that his teacher had said in astronomy class: the Earth-Moon system.

"Gollum!

Tuguhun found that the tide of the sea of vitality was rising, and the first wave of vitality tide was stirring out from the center in all directions.

"What?"

Spit bones and were taken aback.

After the formation of the small universe, the Sea of Yuan Qi was originally a stagnant pool, and he also thought that the Sea of Yuan Qi would be like this.

Who knows, now the sea of vitality has formed a tide!

"Understood," Tu Gu said in his heart, "It should be the appearance of this 'moon' that caused the tidal movement of the Sea of Vitality!"

Tu Guhun clearly remembers that the teacher said in class that the formation of the earth's ocean tides is caused by the interaction between the moon and the earth, and it is not difficult to understand why the sea of vitality formed tides after the appearance of this small black ball.

Seeing the tidal movement of the Sea of Vitality, the Fire Dragon Vitality happily flew up and down in mid-air, and then exploded again with a "poof", turning into a long-tailed comet, and continued to slowly move around the blue sphere.

"Spit bones, spit bones, wake up, wake up!"

An ethereal voice came.

Tu Gu suddenly opened his eyes and found himself lying on the ground, with the anxious face of Master Zuo in front of him.

"Cough, cough, cough!" Tu Gu felt an itch in his throat and coughed violently.

Everyone breathed a sigh of relief.

"I-I'm fine," Tu Guhun stopped coughing and slowly stood up, "I'm not dead yet!"

"That's it for today," Prince Hao Lian stepped forward, "You recuperate for two days, and then talk about it when your body recovers." ”

"Your Highness, has the 'Iron Bird' destroyed the 'Dragon Nine'?" asked.

"No," said Prince Hao Lian, "not even a wound." ”

Tugu Hun looked disappointed, and then he seemed to think of something, "I just got an idea, and I thought I'd test it today." ”

"What inspiration?" asked Master Zuo.

"His Royal Highness the Prince's tactical setting was correct before, it was a mistake to use the 'Iron Bird' to attack the 'Dragon Nine', and the use of 'firecrackers' to bombard the 'Dragon Nine' was the correct solution, but the tactics should also be improved. "Spit bones.

"How to improve?" Prince Hao Lian's eyes lit up.

"The best way for us to dodge the artillery attack of 'Long Jiu' is to find a way to interfere with the detection of 'Long Jiu''s radar, especially the fire control radar, we can use methods such as electromagnetic suppression, or fire smoke grenades and chaff to interfere with it, and then drive the 'firecracker' to get close to 'Long Jiu' through high-speed movement, boom! Blow it up!" Tu Guhun made an explosive gesture.

Prince Hao Lian thought for a moment, glanced at Master Zuo, and then stretched out a thumbs up at Tu Guhun.

"Sure enough, it's true knowledge in actual combat, high!"
