Walking through the ruins of the smelter, Nono looked left and right, and found nothing that was still usable, most of the things were destroyed in the explosion, and only the quartz block of the smelter itself was still of some value.

"Alas!" Sighing lightly, Nuno said: "I knew that I would have started lightly, but I didn't expect the power of this C4 bomb to be so great." ”

Taking out a diamond pickaxe to dig for quartz blocks and quartz slabs, Nono is digging and discovering a secret underground passage.

Squatting down, Nono checked the underground passage to see if there was any water.

Without touching the water, Nuno hurriedly called Ye Yu to his side and told him that he had found an underground passage, which might be the real location of the Biological Research Institute.

Ye Yu heard that Nuo Nuo had made a discovery, and ran to her side to check as fast as he could.

Seeing that there was really a secret passage around Nuo Nuo, Ye Yu suspected that it was the real biological research institute inside.

"If it's a real biological research institute inside, then our C4 bomb has run out, how can we destroy it?"

With a sad face, Ye Yu opened his backpack to see if there were any explosive things in the backpack.

Just as Ye Yu found that there was no explosive thing in the backpack, a grenade popped out in front of him.

Looking in the direction where the grenade came out, Ye Yu saw not only the grenade, but also a white jade hand.

"Where did it come from?" Ye Yu asked Nuo Nuo, and Nuo Nuo told him that he was given to her by Zhao Tiedan.

"How many?" Ye Yu then asked Nuo Nuo, who stretched out three fingers and told him that there were three.

"Alas!" Sighing heavily, Ye Yu said helplessly: "The research institute below doesn't know how big it is, just three grenades, I guess it's difficult to blow up." ”

"Let's go down and take a look first, maybe it's not that big, or maybe it's not a research institute down there."

After Nuo Nuo finished speaking, Ye Yu would rather be bigger at the bottom than not at the research institute below.

Jumping into the underground passage, Ye Yu was shocked by the scene in front of him, the underground passage is made of glass, and the whole is made of glass, and people walking here can see the scene in the icy water outside.

Fish and cod swim happily outside the glass passage, free and seemingly unaffected by the temperature of the water.

Nuno bumped into Ye Yu's back and asked him why he didn't move forward, and then saw the vision, and she was also shocked by the vision.

"It feels like the scene outside the glass passage is like being in an aquarium, let's hurry up, I guess there is a biological research institute ahead."

With that, Ye Yu walked straight forward, and Nuno followed closely behind him.

The glass passage is indeed a bit narrow, and can only be walked by one person, and it is impossible for two people to walk in parallel.

Walking to the end, there was an iron door in front of him, Ye Yu took out the diamond pickaxe to excavate, but found that the diamond pickaxe was very slow to excavate, just like an iron pickaxe digging obsidian.

"What's going on, it hasn't been dug up yet!" Nuo Nuo was a little impatient with the others, and she stuck it on Ye Yu's back to see what was going on.

Digging hard, Ye Yu said to Nuo Nuo: "This is not an ordinary iron gate, I'm afraid it's some kind of special door, fortunately, there is still some progress in the excavation of the diamond pickaxe, and it is not the same as the bedrock." ”

Digging the iron gate, Ye Yu suddenly remembered a very important matter, and he said to Nuo Nuo: "Take the weapon, I'm worried that there may be a lot of guards inside." ”

Nodding his head and taking out his sniper rifle, Nono was ready to kill the enemy.

It was very difficult for Ye Yu to dig an iron gate, let alone dig a gap that people could pass through.

Squatting behind Ye Yu and waiting quietly, Nuo Nuo looked at Ye Yu's speed, and guessed that it was estimated that the door of the research institute would not be able to be dug at night.

"I just hope there's no more door behind the door, or I'll go crazy."

Finally succeeded in excavating a special piece of iron, Ye Yu found that the special piece of iron that was excavated could not be pocketed, and it was directly broken.

"Damn! I thought about digging it up and researching it, but I didn't expect this thing to be broken directly, forget it, keep digging! ”

Ye Yu began to dig violently with a diamond pickaxe, not only did he feel difficult, but even Nuo Nuo, who watched him dig, feel hard.

I couldn't stand it anymore, and Nuno planned to use a grenade to blow open the damn iron door directly.

Occasionally looking back at Nuno to see what she was doing, seeing that she took out a grenade, which looked like she was going to blow up the iron door, Ye Yu hurriedly asked her to stop.

"My little ancestor, you have to figure it out, we are in the glass passage, you make a grenade, the door is not blown open, we will be drowned in the flood."

Ye Yu told Nuo Nuo about the stakes, and Nuo Nuo remembered that the water outside was very cold, enough to freeze people into quick-frozen dumplings.

Putting the grenade away, Nuno pointed to the iron door and said angrily, "Then what should I do?" This iron gate is so difficult to dig, you can't use grenades, you can't use guns, do I just watch you dig so hard? ”

"Do you think I want to dig it?,That's not a way.,This is a password door.,You can't open it without a password.,I'm afraid that entering the wrong password will make what alarm be launched inside.,Then isn't it more difficult for you and me to complete the task?"

Ye Yu was still digging hard, as if talking to him was the best pastime.

Sitting calmly behind Ye Yu and chatting with him, Ye Yu dug for a full hour before digging up the special iron blocks on the two doors.

"How long will it take?" Holding his cheeks, Nuno asked Ye Yu very boringly.

"Hurry! Hurry! Ye Yu dug hard, and it would be about twenty minutes before the third special iron block was dug up.

On the other side of Griffin City, Zhao Tiedan led the city defenders to fight hard and finally cleaned up all the emperor zombies.

After all the emperor zombies were cleaned up, Zhao Tiedan immediately ordered the city defenders to go out of the city to support Chu Jiangcheng, so as not to kill Chu Jiangcheng.

After resisting the army of the Evil Spirit Legion for nearly half an hour, Chu Jiangcheng's strength was about to run out, if it weren't for his strong will to support himself and not fall, I am afraid that he would have been trampled into mist by the iron hooves of the Evil Spirit Legion and left this world.

"Kill!" Holding a trident and charging at the forefront, Zhao Dingjun rushed towards the Evil Spirit Legion, and the soldiers behind him who defended the city rode on war horses with diamond horse armor, all heroic and fierce.

The two sides fought together, and the Evil Spirit Legion was consumed by Chu Jiangcheng alone, and they had no chance of winning when they fought against the defenders of Griffin City.

"Retreat!" The chief leader shouted loudly, and the chief leader followed his orders and led all the soldiers of the Evil Spirit Legion to fight and retreat.

On the lookout in the distance, he used his binoculars to check which side of Griffon's City was going on, and when he saw that his side had all retreated, he didn't get angry, but smiled slightly.

He left the towering lookout, and in the blink of an eye, the whole person disappeared.

Chu Jiangcheng poked the tip of the Taijiao Sword on the ground, and he supported himself not to fall.

"Senior Chu, are you okay?" Zhao Dingjun helped Chu Jiangcheng up and asked with concern.

Gritting his teeth, Chu Jiangcheng exerted himself strength to get himself up again.

"I'm fine, I'm not injured, it's just that my strength is too much, hurry up and help me into the city, just serve good wine and food!"

Chu Jiangcheng said loudly, looking arrogant.

Zhao Dingjun and Steve helped Chu Jiangcheng to return to Griffin City, and Zhao Tiedan asked the soldiers in the city who had no chance to participate in the battle to repair Griffin City.

Griffon City was devastated by the Imperial Zombies, and it may be difficult to repair it to the same as before in a short period of time.

Back at the manager's villa, Zhao Tiedan said to Zhao Dingjun and Steve: "It can't go on like this, if there is another wave of emperor zombies, we will definitely not be able to hold it." ”

"That's right, but I feel that the Emperor Zombie may not come again, I believe that Ye Yu and Nuo Nuo, the two of them will definitely blow up the Biological Research Institute."

Zhao Dingjun said to Zhao Tiedan, Zhao Tiedan nodded, he was looking forward to Ye Yu and Nuo Nuo being able to move faster.

Under the smelter of the Evil Spirit Legion in the Snowy Region, Ye Yu dug out a gap in the iron door after hard work, and he looked at Nuo Nuo behind him, only to see that Nuo Nuo was already asleep.

"Wake up! Wake up! Ye Yu patted Nuno on the shoulder, trying to revive her.

Sleepy-eyed looking at everything in front of him, he stood up and yawned, and Nuo Nuo asked Ye Yu: "Is the iron door open?" ”

"Got through, get ready for battle!"

The diamond pickaxe switched to a meteorite, and Ye Yu was the first to walk into the gap in the iron door that people could pass through, and walked into the interior of the Evil Spirit Legion's biological research institute.

Closely following Ye Yu, Nuo Nuo was holding a sniper rifle, looking like he was ready for battle.

After seeing everything in front of him, Ye Yu believed that this was the Institute of Biology.

Where Ye Yu and Nuo Nuo were at the moment, there were glass covers everywhere that could hold people, and there was a strange green liquid in the glass cover.

"Oh my God, it's so horrible that it feels like the ghost stories in the library." Nuno whispered, and Ye Yu asked her to wait and destroy this place.

The grenade was ready, Nuno was going to blow it up at any time, Ye Yu told her to stay and leave when she left.

The Evil Spirits' Biological Research Institute is a purgatory on earth, where all kinds of creatures are found except for the ender dragon, even withering, soaked alive in a green liquid, like a living dead, unable to attack or move.

"The monarch has an order, let us send him the newly created emperor zombie, the griffin city is about to be broken, we send it as soon as possible, so that the evil spirit army can rule the main world as soon as possible."

A voice came from nearby, and Ye Yu hid with Nuo Nuo to see who was talking.

Wearing a set of white chemical-proof clothes, two men appeared in front of Ye Yu and Nuo Nuo, their mouths kept moving, as if they were communicating something.

The voices of the two men could still be heard just now, but now Ye Yu and Nuo Nuo are like deaf people, they can't hear anything.

Looking at Nuno, who was only a few blocks away from her, Ye Yu motioned with her eyes to prepare to make a move.

Nuno understood what Ye Yu meant, and aimed the sniper rifle at a man's brain.

Ready to launch the meteorite, Ye Yu threw the meteorite, and the extremely sharp dart shot towards one of the two men not far away.

"Bang!" The sound of gunfire resounded throughout the Institute, and the sound of this gunfire alarmed everyone in the Institute.

Holding his forehead, Ye Yu was a little speechless in his heart, he forgot to tell Nuo Nuo not to use a sniper rifle, but to use a silent bow and arrow.

At this point, the only way to do this is to kill them head-on and get rid of all these evil guys in the research institute.

Ye Yu and Nuo Nuo opened the killing ring and destroyed all the evil researchers in the Biological Research Institute.

Staring at a glass cover, Nuno saw a creature that she had never seen before, she asked Ye Yu, asking Ye Yu if he knew what the creature was.

Seeing where Nuo Nuo was stunned, Ye Yu hurriedly ran to her side and asked, "What's wrong?" ”

"What kind of creature is that?" Pointing to the creature in the glass cover, Nuno asked Ye Yu.

Ye Yu looked at the creature in the glass cover, and was also a little surprised.

The creature in the glass cover was a scorpion, Ye Yu had never seen a creature like a scorpion since he came here, but he didn't expect to see it in the Biological Research Institute of the Evil Spirit Legion.

"This is a scorpion, one of the five poisons, and the thorns on its tail are very powerful, and a bite will make people feel painful."

Ye Yu told Nuo Nuo what the creature in the glass cover was, and then the explosion suddenly sounded, and the explosion was not very far from him and Nuo Nuo.

"Let's go, let's take a look!"

Pulling Nuno to run in the direction where the explosion came from, after Ye Yu and her ran to where they went, the whole person was stunned in place, a glass cover was broken, and the green liquid kept flowing out, and soon it was clean, and it seemed that the creatures inside had run out.
