Zhang Yongwang.

Huaguo veteran one-star grandmaster, one of the gatekeepers of Changbai Mountain.

For decades, he has been guarding the base of Changbai Mountain all year round to guard against the invasion of strong people from other countries.

In the inner world, some people even call him the 'guardian saint of the northern plains' as a sign of respect for this old master.

However, to everyone's surprise, on the fifth day of the opening of the Tianchi Secret Realm, Zhang Yongwang suddenly betrayed!

Xue Honglan, the sect master who is also the gatekeeper, was attacked by Zhang Yongwang and was seriously injured on the spot, his heart broke a bloody hole, and his body fell into the depths of Tianchi, and he didn't know whether he was alive or dead.

On this day, the blood of the grandmaster stained the Tianchi of Changbai Mountain red!

"Don't be stubborn, you don't have a chance. ”

Zhang Yongwang was dressed in black, standing in front of the tightly sealed alloy gate, with a cold voice, the air seemed to be frozen: "Liu Cangqiu, open the gate and hand over the design of that weapon, this sect can spare you from dying." ”

Behind the metal gate, no response came.

For a moment, the air seemed to freeze.

However, Zhang Yongwang was very patient, carrying his hands behind his back, and his voice carried a faint chill: "I really can't break the defense here with my own strength, but how long can you hold out inside?"

"No food, no water, no means of external communication, can you hold out for three days, or five days?"

"What's more, it's not just this sect that will come next. ”

In order to ensure the safety of the drawings of that weapon and the absolute secrecy of the research and development process, the entire underground research institute building is made of special alloys of incredible strength, which even the grandmaster cannot break in a short time.

Not only that, but the entire underground research institute has been physically closed.

There is no external network, no communication signal, so as to avoid any possible information leakage.

In other words, once the alloy door is locked, the entire underground research institute will immediately become an isolated secret room, unless the people inside reopen the door!

Behind the alloy gate, Liu Cangqiu looked at the picture on the monitor, his face was extremely solemn.

Beside him, there were many warriors, their faces were also solemn, and some of the special fighters of the base looked at each other at this time, not knowing what to do at all.

No one thought that the dignified guardian saint of the Northern Plains would suddenly rebel!

The news was so shocking that many people are still dizzy and have not recovered from the upheaval.

"Elder Liu, isn't Senior Zhang the Patron Saint of the Northern Plains, why would he betray us?"

"What is the weapon drawing that Zhang Yongwang said?"

"What the hell is he trying to do?"

"What is the secret of the Changbai Mountain base?"

One Martial Dao innate trembled, as if shrouded in a huge cloud, and there were bursts of chills all over his body: "With such a big news, didn't the Chinese government get any news in advance?"

Liu Cangqiu took a deep breath, as if a thousand heavy burdens were pressed on his body, making his figure become more and more rickety: "Do you think that the country has controlled the Tianchi Secret Realm for so many years, and it really hasn't done any exploration work at all?"

"Could it be that weapon—" Someone's face changed slightly, apparently aware of something.

"That's right, just thirty years ago, at the cost of twenty-six congenital falls, the Chinese government unearthed a mysterious weapon blueprint in the secret realm, if it can be successfully developed, it will definitely change the pattern of today's world!"

Liu Cangqiu's words made everyone change color.

Once, the birth of nuclear weapons changed the pattern of the whole world, and the five major powers stood on top of the world, and no one dared to challenge them.

The science and technology of today's countries are more advanced than at that time, what kind of weapon can actually change the pattern of the entire world and make a generation of grandmasters be sentenced for it?

"Senior Liu, what the hell is that weapon?" someone swallowed.

"Don't say it, don't say it!" Liu Cangqiu shook his head deeply, his eyes filled with deep jealousy, and at the same time shouted sharply, "No one should think of handing over that drawing! Once it falls into the hands of other countries, we will be the sinners of the entire Chinese country through the ages!"

If it weren't for the emergency, he wouldn't even have fled here with the crowd.

Everyone was silent.

Three days are fleeting.

During these three days, the Changbai Mountain base was completely lost to the outside world, and there were communication soldiers who came to investigate the situation, but they were all ruthlessly killed by Zhang Yongwang.

Zhang Yongwang's eyes were very cold, with determination, and he did not leave the slightest emotion.

From the moment he decided to betray, he had embarked on a path of no turning back, leaving no room for regret or hesitation.

"Don't blame this sect, this sect was seriously injured when it attacked the grandmaster, and the longevity was greatly reduced because of this, and the general method of prolonging life has long been useless for the grandmaster!"

If it weren't for the approaching deadline, how would he choose this path of no return?

Suddenly, Zhang Yongwang's expression moved, and he saw several black shadows suddenly appear from a distance, quietly breaking into the base of Changbai Mountain.

The men were divided into two distinct groups, one of them was yellow-skinned and black-skinned, dressed in samurai clothes, and the other was burly and had short flaxen-colored hair, apparently from two different countries.

"You're late!" Zhang Yongwang said in a deep voice, and the voice reached the ears of those people.

"Hehe! Huaguo's inspections these days are too strict, and we have wasted a lot of effort and found a lot of special channels to get in safely. ”

One of the gray-clothed warriors smiled strangely, and said with an awkward Chinese: "This drawing is behind the gate, let me try a few slashes first......

"East Asian elves, don't waste time. The tall Russian squinted, and his rumbling voice vibrate, "We don't have much time to waste, do it now!"

He shouted angrily, the muscles of his whole body bulged, and the short clothes on his body burst open, the big cyan tendons were exposed, and his body suddenly rose more than ten centimeters, just like a humanoid bear!

"Hey, Russians, we don't have conflicting goals, don't scare you with your abs. ”

The three samurai of Sakurajima drew their swords at the same time, and their incomparable aura skyrocketed, like three divine swords, and the terrifying sword intent almost penetrated the gate of the alloy.

The other three Russians also bloomed, all of them tall, like tyrannosaurs, emitting a terrifying and ferocious aura that made the soul frightened.

Behind the alloy gate, Liu Cangqiu's eyes widened, his body trembled suddenly, and he exclaimed on the spot:

"Sakurajima's Okita Three Musketeers, and Russia's Alpha Biochemical Force fighters?

"Old Liu, who are they?" Seeing Liu Cangqiu so out of shape, someone couldn't help but ask.

"In terms of strength, each of these seven people is equivalent to a grandmaster who has not yet survived the decay!"

Liu Cangqiu's voice was extremely difficult, and he said word by word: "They and Zhang Yongwang join forces, which is almost equivalent to three one-star grandmasters, which is enough to break through the defenses of this laboratory!"

As soon as these words came out, everyone fell into a dead silence!
