While......

There was another loud bang, the space collapsed, the wind howled, and Yu Lingtian only felt that the true qi had passed again, and the person was also unstable on his feet, like a rolling gourd rolling away.

Zhang Dong took a few steps back, then stabilized his body, chased after him with an arrow step, slashed wildly, and slashed Yu Lingtian with a hundred knives in a row!

Because he could absorb the other party's true qi to supplement his own consumption, the swords and knives were all in peak state, and Yu Lingtian had a rapid decline in force value because of the passage and consumption of his true qi, and after blocking a hundred swords, his tiger's mouth finally burst, and the golden sword in his hand also fell to the ground with a bang, and the person was also extraordinarily wolf, with a cloak and a dense blood stain on his body.

But he smiled weirdly, and the place where he was standing suddenly sank, like a meteor falling, and disappeared without a trace in the blink of an eye.

"Unexpectedly, you let the duck fly away?"

Zhang Dong was a little surprised, and when he looked at the place where Yu Lingtian had sunken, he found that it was a dark tunnel, bottomless, dark and cold, exuding an evil aura

He immediately began to watch the cave and Yu Lingtian's surveillance video, and only when the detection was clear, he would catch up with it, kill it, and use the opponent's blood to increase his strength.

This tunnel is more than 2,000 meters deep, and every other distance, there is an iron plate blocking it, but when Yu Lingtian falls like a meteor, these iron plates will automatically retreat, and as soon as Yu Lingtian passes, these iron plates will automatically block the tunnel.

Soon, Yu Lingtian fell to the bottom of the cave and entered a strange hall laterally, with an area of about 2,000 square meters, filled with dense high-tech instruments, under the illumination of strange lights, it reflected a cold light.

One of the instruments was oddly shaped, shaped like a coffin, with small tubes extending from the walls of the coffin and connecting to the rest of the instruments.

This instrument is one of the highest scientific and technological achievements of the Rain Clan, the most advanced genetic enhancement instrument, which can make the Rain people stronger into stronger beings.

However, there is a limit to genetic enhancement.

Yu Lingtian has been strengthened to this point today, which is basically his limit, after the analysis of the Rain Clan scientists, if Yu Lingtian is strengthened again, the chance of success is less than fifty percent, and once it is not successful, it is death, of course, if it succeeds, his strength will be greatly improved.

As a high emperor and with an infinite lifespan, Yu Lingtian naturally spared his life and never thought of strengthening it again.

However, today, he came to this place in the twilight of his life.

He flicked a switch, and the gene enhancer silently popped out a lid, revealing a rectangular space inside, some red sè solution flowing in from the connected hoses, and some strange powders also flowing in from other tubes, emitting a strong medicinal fragrance.

The solution gradually thickened, as if it were a red gruel.

It can be seen from this program that although the people of the United States got it in the past was also a genetic strengthener, it was the lowest level that had long been discarded, and there was no drug and special solution configuration, and the people of the United States forcibly strengthened, and it was understandable that so many soldiers had died, and it was natural that the success rate was so low.

A complicated expression appeared on Yu Lingtian's face, and a trace of sadness flashed in his eyes, but it was quickly replaced by viciousness, and now the Rain Clan was the only one left, and the enemy who killed the Rain Clan was outside, but he was not his opponent, and the underground space had been closed, and he couldn't get out at all, and the blood bank was also destroyed, he didn't have blood to drink, and the worst thing was that the sleeping device was also burned by the fire, and then buried by the mud and stone, it was impossible for him to even sleep.

In other words, I have no chance of living.

In this case, why not fight, once the genetic enhancement is successful, he can become much stronger, he can go out to kill Zhang Dong, drink his blood, and look for a chance to escape, otherwise, don't say escape, as long as you go out, you will be killed by the other party.

Of course, if you die in the genetic enhancer, you will have no regrets, and your blood and crystals will not be obtained by the other party.

Thinking of this, he stepped in and lay inside, the lid closed silently, and the instruments in the entire hall were all working wildly, flashing with all kinds of strange lights, looking as terrible as hell.

Paying attention to these, Zhang Dong not only did not panic, but instead had a thick surprise on his face, and muttered: "Yu Lingtian, you must not let me down, you must succeed in genetic strengthening, then, the effectiveness of your blood will definitely be greater, I am looking forward to it, I am looking forward to it." ”

If Yu Lingtian could know what Zhang Dong was thinking, maybe he would rather die in the genetic enhancement instrument than come out.

Despite his self-confidence, Zhang Dong was not too arrogant, and put the fairy cave into a crumbling earth, and then entered it.

The sky of the fairy cave was empty, and the soldiers and human coalition troops in it had all gone out, and only more than a thousand Mi people were still working in the factory converted into the main hall.

Zhang Dong did not enter the main hall, but came to the island in the center of the lake, sat cross-legged, closed his eyes, and began to inquire about the situation of the three million human alliance troops that were taken away by Long Tongxu with his sleeve.

At that time, the three million coalition troops and the soldiers cultivated by Zhang Dong were thrown outside the base by Long Tongxu, and they were naturally extremely surprised, and they were sincerely afraid of this person.

Then they saw that the entrance to the base had collapsed, and found that Zhang Dong was not here, so they panicked and began to dig the entrance frantically.

However, the fact that the earth at this entrance had become many times harder than steel, and no matter how much they dug it, they could not shake it in the slightest, made everyone's eyes stunned, and a bad premonition rose in their hearts.

Zhang Dong's subordinates and the Eagle Clan were even more anxious, although the excavation was useless, they kept digging until they had exhausted their true qi and were unable to collapse to the ground.

Zhang Dong was very moved, and said in his heart: "Brothers, my clansmen, don't have any worries, although I am trapped in the space below, I will get out of the predicament in a month or a year." I also want to tell you that I have already defeated Yu Ling Tian, and I have broken through a bottleneck and become extremely powerful...... You go back first, create a new pattern in the world, and let mankind embark on the path of cultivation from now on. ”

These words were naturally transmitted to everyone's minds by the monitor.

Everyone cheered and was truly relieved.

Of course, Zhang Dong is not bragging, he does have a way to get out of trouble, although Long Tongxu has turned this place into an impenetrable prison, although Long Tongxu doesn't want Zhang Dong to get out alive, but Long Tongxu never dreamed that Zhang Dong has a monitor and Huitian, as long as the monitor collects enough energy, he can use Huitian to travel through time and space, go back to the past, and then travel back, naturally it is easy to get out of this damn underground space.

Therefore, although Zhang Dong was very angry at Long Tongxu's behavior, he was not panicked at all, how could he trap himself in a mere prison?

He closed his eyes cross-legged, meditated, and began to peruse the scene of this breakthrough, hoping to enter the illusion of breakthrough again.

He was not disappointed, and the black hole and fireflies reappeared.

It seems like a moment, and it seems like countless years.

The illusion was shattered, Zhang Dong also woke up from the wonderful realm, his face was full of surprised smiles, this time the black hole devoured the number of fireflies, far more than the previous times, he comprehended the rules and principles of heaven and earth is naturally extraordinary, after all, breaking through from a pickle girl apprentice to a pickle girl master is the most important intersection on the cultivation path, marking the success of the martial artist or truly finding his own way.

These comprehended rules and principles of heaven and earth are basically related to the way of swallowing and the way of mistance, but there are still outliers among them, and there are even five rules of heaven and earth of the golden way.

Zhang Dong has tasted the sweetness of the rules of the Golden Dao Heaven and Earth, and has comprehended a total of two before, blessed on the weapon, he can increase his force value by 7,000 points, and now he has comprehended five, and then blessed on the weapon, how much will the force value increase?

He's looking forward to it!
