"Using this, the sound is powerful and powerful." Chen Shisan took out three iron lumps from his pocket and said to Xiao Nan.

"Hand grenade." Xiao Nan was startled, but she did not extend her hand to receive it. She said with a complicated expression on her face: "Right now, this is the only thing I can use, but I don't have enough stamina, and you can still project. Remember, this thing needs to be unlatched first, and then, you need to let go and throw it out.

After explaining the method to use the grenade to Chen Shisan, Xiao Nan hugged him tightly, so that Chen Shisan could free one hand to throw the grenade.

Chen Shisan easily grasped this kind of work that did not have much skill. After the grenade in his hand adjusted to its weight, he got Xiao Nan to help him unlatch it, and threw it into the hole of the mine. To him, a 20 meter distance was nothing. As expected, the grenade flew very slowly in the air and was about to run out in a few seconds.

With an explosive boom, before the dust and sand fell from the sky, Chen Shisan had already rushed over. Xiao Nan used her senses to continuously shoot at her surroundings, suppressing the enemy so that she couldn't move.

In just a few breaths of time, Chen Shisan had already ran to the entrance of the mine, and there was a broken body lying beside him. He was too careless, he never thought that Chen Shisan would actually find a hand grenade on his comrade's body, and accurately shoot it over. "Previously, he didn't even seriously look for a shelter to hide from, only dying so straightforwardly and thoroughly.

"Are we going to guard here or enter the mine?" Chen Shisan asked. He was very happy that he had reached the target.

"Don't stop, quickly go in. The deeper the better!" However, Xiao Nan urged her urgently with a face full of anxiety.

Chen Shisan didn't think too much and started running with Xiao Nan on his back. However, the tunnel didn't extend too far, it was only around seven or eight meters long, and they arrived at the end.

Not waiting for him to carefully observe, several hand grenades flew in from behind him. Some of them exploded as soon as they arrived at the cave entrance, and an air wave instantly swept over …

"Jump!" Xiao Nan only had time to scream before she was sent flying by the shockwave and fell into the vertical shaft.

Rumble … Rumble …

There were more than ten hand grenades thrown in continuously. The enemy was determined to blow up the mine tunnel.

Previously, when Xiao Nan took out the hand grenade, Xiao Nan was worried. Since the enemy had brought out the hand grenade, they must have used it at the last second, regardless of anything else. It was only that she did not explicitly tell it to Chen Shisan in that situation. She knew that it would be useless even if she said that. If they didn't rush into the mine, they would die, and using a grenade to charge in would be a narrow escape. But at least there was a chance of survival.

The hand grenades continued to explode, and the mine's entrance was finally unable to withstand it any longer. Large chunks of rock fell, and finally collapsed with a loud bang. At the same time, stones rained down through the hole.

The piercing sound of sirens came from the foot of the mountain. The four criminals came out of their hiding places, gave the collapsed mine a sinister look, and scattered in all directions. They didn't even bother with the corpses of their comrades.

Half an hour later, the highest ranking officer of Jiangdu City, Hu Zhigang, had already arrived at the scene. In fact, as long as the leaders of both the large and small cities were present at the scene, the reinforcements for the local army would also be on the way. Such a terrorist attack, not to mention Jiangdu City, was an exceptionally large case that was rarely seen even in the entire country.

"Over a hundred warheads have been discovered at the scene."

"There are many traces of grenades exploding, we've already found two dead and one heavily injured …"

"Continue to investigate the scene and search for survivors. Contact the bomb expert and have the hospital prepare to receive the wounded …" As Hu Zhigang listened to the report, he hastily issued an order.

"Reporting, news came from the hospital. Officer Xiao Nan disappeared, the last witness said that she and Chen Shisan went up the mountain an hour ago." Suddenly, someone came to report.

"What!?" Xiao Nan went missing, or was she on this mountain? " Hu Zhigang exclaimed in shock, and his complexion turned even uglier than before.

"Quick!" Notify Captain Xiao... I'll let you know myself. " Hu Zhigang panicked and quickly found a phone to make a call.

"Everyone pay attention, immediately search for Officer Xiao Nan's whereabouts." The deputy director gave the order in Hu Zhigang's place, and more police officers joined in.

Two hours later, the scene was almost cleaned up. The search for the criminal had also been carried out in full strength, but there was still no result from searching for Xiao Nan and Yue Yang.

Xiao Jianfeng had already reached the scene, but he was frowning right now, standing in front of the collapsed mine cave entrance, he asked the explosion expert that was accompanying him: "Did it just collapse?"

"Yes, it should have been caused by the last explosion." The expert affirmed.

"How deep is this mine? Are there any other tunnels?" Xiao Jianfeng asked again.

"No, this is a mine that has been abandoned for many years. It was sealed back then due to the water seeping through its interior. The shaft alone is 800 meters deep. " This time, the one who answered was a grizzled old man, he was once the mine manager of this iron mine.

"Hurry and save them, Xiao Nan and the others are definitely inside." Xiao Jianfeng did not ask anymore, and decisively waved her hand.

The specialist and the mine manager muttered to themselves. Even if the people hiding in the shaft weren't killed by such a violent explosion, they would have been blown into the shaft and died. Was there a need for rescue? The cost of rescuing this abandoned mine was easily several million or even tens of millions. Was it worth it?

However, with Xiao Jianfeng's special identity, they did not have the courage to oppose him. Even if they were to mutter to themselves, they did not dare to show it.

After a day had passed, the air supply pipeline to the shaft had yet to be opened. The tunnel's excavation was also not smooth, and they were only able to push forward a little less than five meters. The explosion had already caused the nearby mountains to loosen up, and the amount of sand that needed to be excavated was astonishing.

The police force had already retreated, and the ones left at the scene were all Xiao Jianfeng's soldiers, as well as a huge rescue team of two hundred people. There were more than ten large machines that had arrived at the scene, working non-stop day and night.

Xiao Jianfeng's eyes were bloodshot, he was still guarding the place, but as time passed, his temper became more and more explosive.

There was no result from the rescue mission, there was no news at all on Xiao Nan and Yue Yang, they could not even be sure that they were inside the collapsed mine, it was only Xiao Jianfeng's stubborn judgement.

On the contrary, the hunt for the criminal was progressing. The seriously injured gangster had yet to awaken, but the police still found a lot of clues from him. These people were all notorious offenders. All of them were vicious and merciless. They were all employed by a large drug lord called Spiked Tiger.

The Spiked Tiger had a huge presence in Southeast Asia, controlling more than 80% of the drug trade there. It had thousands of followers, and it also had its own private army in the forest. The purpose of this assassination attempt on Xiao Nan was also very clear; The last time Xiao Nan led the team to battle with the big drug dealer, it was to capture Kuang Long and the others. In the end, Xiao Nan received serious injuries, and the police sustained more than ten injuries before finally exterminating Kuang Long's group.

As Kuang Long's biological brother, how could Spiked Tiger endure this anger? That was why he spent so much money to hire assassins, infiltrate the Jiangdu City to assassinate Xiao Nan, and seek revenge for his brother.
