During this time, Zhang Hao pulled a few new friends, plus Hu Gang, ate and drank more than a dozen times, and went to the city museum several times by getting to know Jin Lao.

In the Municipal Museum, Zhang Hao came into contact with many cultural relics, and he began to develop a lot of interest in some materials, archaeological discoveries, and ancient texts.

In particular, Zhang Hao was particularly interested in some Taoist texts and Buddhist texts, and he found that many of these texts involved the soul and the body, which should be helpful as a reference for his cognition of the soul.

A month later, Mi Feng came back, bringing good news, he and Sister Yin helped Zhang Hao prepare enough materials, plus the bridgehead framework given by Sister Yin before, this time it is going to reverse time and space, and Sister Yin is also going to come over and help Zhang Hao build the first bridgehead together.

This time it's a newly developed technology, the most awesome black technology!

Zhang Hao didn't expect to be able to build his main bridgehead so soon, he was very excited, and deliberately entered the sealed bridgehead to conduct soul testing, this time it was the equipment brought by Yin Zhifeng, and his soul was barely enough.

This time, there are thousands of robots in the past, as well as various large-scale engineering mechas, battle mechas, and a large number of material resources. Except for a few robots left by Zhang Hao, the robots that belonged to him were basically taken away.

…………

The clouds rolled, the wind blew fiercely, and the wind, with a slight hint of earth, quickly swept across the earth, making a peculiar whining sound, as if a huge horn was blowing.

"Click...... Rumble! ”

There was a thunderclap, thunder and explosions, lightning stabbed the earth, and the shrubs and weeds trembled against the wind.

It is a savannah, facing north of an endless line of low shrubs and wild grasses, and as far as the eye can see, it is a line of white sky.

To the south is a mountain range that looks like a dragon, and when the lightning illuminates the earth, this mountain range stretches like a dragon crawling on the ground.

Near the mountains are undulating hills, gradually extending to the grassland, the earth is flat, and the inky earth, meandering are small rivers, reflecting the electric fire and thunder, which is extremely eye-catching.

The sky was getting darker.

Suddenly, the dark black clouds flashed with dazzling light, as if countless silver snakes pounced on the earth, and the rolling thunder exploded, like the beating of a heavenly drum, bombarding all the way from the sky.

In the crackling sound, the rain poured down.

In an instant, there was a white fog all around, and at the same time, the sound of the rain also covered everything around, and as far as the eye could see, it was no more than ten meters away.

On a small hill not far from the mountain range, with a flash of lightning, a figure suddenly appeared on the originally empty hill, and the person was half-squatting on the ground, as if shaken by the sudden heavy rain, and kept squatting there, motionless.

The rain hit the man, but it couldn't wet the black trench coat he was wearing, and the rain fell on the clothes, quickly turning into tiny droplets and splashing out, but the man's short hair was completely soaked, and the water flowed down his face.

The man wiped his face, it was a young face, ruddy, black sword eyebrows, a pair of bright eyes, he held the collar tightly with both hands to prevent the rain from sliding into his neck, and from time to time he freed up one hand to wipe the rain from his face, because he was half-squatting, so his trench coat could cover his body.

The thunderstorm on the prairie came and went quickly, and in just a few moments, the rain eased.

The heavy rain that had been tearing down the sky gradually became sparse and the sky gradually brightened.

The man stood up, this was an extremely burly person, squatting was not obvious, once he stood up, he was suddenly different, he was one meter nine tall, and his spirit of strength came to his face.

He ran fast, the speed was simply terrifying, and in a moment, a radius of ten kilometers was run by him a few laps.

The man took off his trench coat, he was carrying a small silver backpack, he took off the backpack and opened it, he took out a small box, which was an inconspicuous small black box, he put the small box on the ground, and stepped on it with his feet.

Click, and the little box sank into the ground.

The man said, "Program on!" Two red rays shot out of his eyes and nailed to the small box just now.

There was a click, and the small black box suddenly expanded downward.

A beam of three-dimensional light shot out from below, revealing two other robots.

Triangular area, triangular positioning, three people, three real robots.

Zhang Yihu, Zhang Erhu, Zhang Shanhu!

Positioning complete!

The three rays of light form a three-dimensional triangle, and as the triangle is formed, the light curtain lights up and a huge pyramid of light appears. Of course, this is not a four- or eight-sided pyramid, but a three-sided pyramid.

Start converting!

The white light curtain of the light pyramid gradually darkens in color, with white light to yellow, orange, red, crimson, purple red, purple black, and finally it is like the universe, the black light curtain is dotted with stars, flashing countless points of light.

The time of one day and one night.

Conversion successful!

The bridgehead structure is revealed.

It was a three-sided pyramid, a metal frame structure, a huge pyramid, six thousand meters high, like a huge mountain, everything in the pyramid was revealed, inside was a honeycomb structure, all of which were carrying supplies.

Zhang Yihu ran towards the pyramid, this is the basic structure of the bridgehead, it cannot be hidden in time and space at present, only after the construction is completed, and then opened, can it really enter time and space.

He had to turn on the energy supply inside the bridgehead, otherwise the other robots wouldn't be able to start.

Entering the bridgehead, if you want to enter the most core part, you need a long line, Zhang Yihu is extremely fast, and he has the nearest terrain route map in his soul.

The core part is a huge silver ball, like a giant hollow ball, and there is another small ball in it, a big ball set of small balls, this small ball is at the bottom of the hollow ball, and the small ball that Zhang Yihu saw was the silver ball he saw when he entered the hollow ball.

The diameter of the big ball is more than two thousand meters, and the diameter of the small ball is five hundred meters, Zhang Yihu looked up, judged it a little, and immediately walked like a fly, running frantically towards a small platform on the inner wall of the big ball, the speed was extremely fast.

In a few minutes, Zhang Yihu got on the small platform, which was built on the inner wall of the big ball.

The area is less than eight square meters, a very small platform, on the inner wall of the big ball, if you don't pay attention, you can't see it.

One after another, the light screens rose, Zhang Yihu took out a palm-sized piece of metal from his waist, inserted it directly into the groove on the ground, and then started the program.

A larger light screen appeared, and above it was the honeycomb structure, which was the storage space used in the future, of course, it was not a storage space now, only when the bridgehead entered the time and space, the concept of storage could be established. It contains a lot of packed small space, and because a large number of materials need to be transported, a lot of materials must be packed.

First of all, the robot that is to be released.

The first to be released was Zhang Hao, the wind of sealing and sealing, these three people are the ones who really control the bridgehead, of course, they are all robots here, and real living people can't come over.
