"Roar!" Dozens of mutant beasts jumped out, and as a result, they did not rush towards the zombie group, nor did they rush towards Shen Yan, but rushed towards the zombie corpses that were killed by Shen Yan.

"You're having a good plan." Under the detection of bioradar, Shen Yan has always been aware of the movements of the mutant beast, but what he didn't expect was that the other party actually pounced on the corpse of the zombie, obviously they judged that Shen Yan was not easy to mess with, and just wanted to snatch food from his mouth.

"Whew! Shout! Shout! ”

Silently, three cold rays of light shot rapidly towards the mutant beasts, and blood lines shot out, and those mutant beasts that suddenly appeared were already dead on the spot. Tang Haotian's position was at the corner of the other end, although the distance was close, but because of the angle of view, they couldn't see the mutant beast, and could only hear it. Shen Yan swept all the way, put those killed mutant beasts into the storage space, and then reflexively killed the zombies.

"You guys help me collect crystals, be fast!" Shen Yan rushed back into the zombie group, and shouted directly to Tang Haotian and the others as the killing began.

"Poof! Burst! Burst! ”

A pair of dragon teeth were like two thunderbolts, and the cold light flashed across the necks of one zombie after another, and then as Shen Yan's body moved forward for a while, the heads of those zombies rolled to the ground one by one, and the whole process was like a dream, as if those zombies were standing there waiting for Shen Yan to pass by, and then they all fell to death.

"Tsk, this guy...... It's so speechless, we follow him into the city, not only are we not in danger, but we have to reap the spoils of war here! Tang Haotian was summoned by Shen Yan and led his subordinates to hurry, including him, who collected the crystals one after another.

"After some time ago, I have improved a lot in my body method, and my mental power control has also grown a lot. But I feel that there is always a feeling that I can't do it all! Shen Yan sighed in his heart during the killing.

Now the number of mutant beasts and zombies slaughtered in his hands has exceeded 300,000, so many of them have made his killing methods much more sophisticated than before, but it still makes him feel that he can't use all his power to the fullest. This shows that he still lacks a lot in some aspects.

"This is the disadvantage of not having a suitable cultivation technique, master, and not having a suitable combat secret method. You must know that whether it is an exercise or a secret method, it is the result of long-term exploration and summary by predecessors, and it is the best way to give full play to the strength of the body. Of course, when the strength reaches a certain level, the self-created income is the most suitable for yourself! Hearing Shen Yan's exclamation, Mira's voice sounded at the right time.

"Yes, the national techniques that you summarized seemed to be very profound at the beginning, but when you really use that method, you still feel that there is a big deficiency." Shen Yan responded with emotion.

"After all, the time is too short, only a few thousand years, and there is no corresponding strength in the process of summarizing, so it is of course that it is lacking. But then again, the art of mind cultivation on the earth is good, and the level of mood still has a very big impact on the improvement of a martial artist's strength. Mira said.

"Well, since that's the case, I need to continue in this aspect, as for the exercises and secret methods, I will give up first, just hone my speed and strength." Immediately, Shen Yan determined his early goal.

After determining the initial goal, Shen Yan mainly focused on speed and strength.

Speed and reaction, in the face of constant sudden obstacles, can move at will; The strength is related to the size of the output, and the most suitable effect is obtained with the least effort. The combination of the two is to use the simplest, most labor-saving, and most effective method to solve the opponent instantly.

"Whew, it's finally finished!"

Shen Yan ended the battle early, thousands of zombies only took less than ten minutes under his killing, but it took more than an hour for Tang Haotian to collect the crystals, during this time Shen Yan did not help, but divided his heart into two uses, while pondering his future cultivation path, while using the Five Hearts to Heaven method to absorb star energy. This was a habit he had formed since he set out from Ning Province, in order to provide Mira with a continuous supply of star energy. After all, relying solely on killing to obtain star energy, Mira's subsequent upgrades are too slow!

"Let's go, let's keep going." Hearing Tang Haotian's voice, Shen Yan smiled and got up.

The whole team was in a city where tens of millions of zombies were gathered, and the mutant beasts were even more unknown, and they were in a completely relaxed state.

Since Shen Yan's first battle, he has encountered a group of zombies almost every kilometer or so, and he will encounter a group of mutant beasts from time to time on the way. Fortunately, more than half of the journey has been completed, and Shen Yan's wish to reach the target place before evening can be achieved.

Finally!

After more than three hours, Shen Yan and his entourage came to the outside of the three buildings that Tang Haotian had pointed out before at about five o'clock in the afternoon.

Looking at the three towering buildings in front of him, Tang Haotian couldn't help but feel a little energetic, "Thanks to Shen Yan this time, otherwise we wouldn't have been able to come here at all, I hope our goal this trip can be as smooth as when we came all the way." ”

"Actually, your credit is not small, if I were alone, I wouldn't have been able to get so many crystals!" Shen Yan This is also to be honest, there are five groups of zombies encountered along the way, the number ranges from seven or eight thousand to ten thousand, so many zombies let him collect crystals alone, he really doesn't have that patience, he really has done too many such things along the way, and he feels like he wants to vomit when he thinks about it now.

Tang Haotian glared at Shen Yan depressedly, the twenty people under his command were all people he had carefully selected for this mission, but who would have thought that after coming all the way here after converging from the village outside Yangyuan Town, there was basically nothing to do with them. Now that they have entered the city, they have directly become cleaners, what will be the reaction of such a huge gap after hearing Shen Yan's words? It's a pity that they can't refute these words, and they really can't refute them at all.

While speaking, under the leadership of Shen Yan, the group of them began to walk towards a small building surrounded by three buildings, only five stories high. If Shen Yan still had a feeling of unattainable when he looked at the three buildings before, those who now looked at the building surrounded by the third floor had a strange meaning in their hearts. It's such a strange combination!

As if seeing Shen Yan's strange expression, Tang Haotian smiled and explained: "When this place was planned to be rebuilt, this scientific research institute was conducting an urgent study, and in order not to affect the progress of the research, these three buildings were finally built first. Who knows, not long after the three buildings were built, disaster struck, and it ended up like this. ”

"I see!" Shen Yan nodded.

"Huh?" Just when Shen Yan walked all the way and came to the gate of the building, the bioradar that had been unfolding turned out to find a creature. It wasn't a zombie, it wasn't a mutant beast, it was a human, and it was a human with a level four enhancement.

"How is it possible, could it be that there are already forces that have researched enhancement potions and started to create enhancement people?" Shen Yan was extremely surprised in his heart.

The bioradar detected that there were six people in the building, and the six people were not stuck, but were walking around the interior in a very regular manner, to put it simply, as if they were patrolling in a fixed trajectory.

Shen Yan hurriedly flashed aside, then looked around, and soon found several cameras on the front of the building. Fortunately, the angle they approached before was a dead end, and then Shen Yan found it quickly, and it was not captured by the camera.

"Are you sure there's no one at this institute?" After avoiding the camera, Shen Yan immediately asked Tang Haotian.

Tang Haotian nodded subconsciously, but after seeing Shen Yan's serious expression, he hesitated a little: "I'm not sure!" At the beginning, after this scientific research institute researched the stock solution, the capital sent troops to meet it, preparing to send the stock solution to the capital. But the troops were besieged by zombies when they arrived and set off, and finally the capital was cut off from here. In the following time, both Jingcheng and General He Weiguang sent troops, but in the end they did not complete the task because of the environment here. So...... I'm not sure if there's really no one here. ”

Shen Yan understood that Tang Haotian and the others did not see it with their own eyes, but only guessed according to the current environment. Then it means that the people detected by the bioradar at this moment are likely to be the people who survived after the escort force was besieged by zombies, and it is also possible that the survivors here have been discovered.

It's located in the heart of the city, and there are plenty of shopping malls around it, so if it's a fortified person, they won't have a problem getting supplies for their survival. Moreover, this scientific research center is located underground, and if the materials are sufficient, it can indeed survive the siege of zombies. But they obviously had the strength, but in the end they didn't leave here, which made Shen Yan a little puzzled!

"What the hell is going on, why don't you go in when you're at the door?" Seeing Shen Yan's contemplative appearance, Tang Haotian couldn't help but ask.

"Let's not go in for the time being, let's find a safe place to rest nearby!" Shen Yan shook his head, seeing that Tang Haotian's eyes were still full of doubts, he said solemnly: "It's not that I don't want to go in, it's that I just found out that there are people in this building, and we can't go in for the time being without figuring out the inside." ”

"What, there's someone in there?" Tang Haotian was startled, but soon understood, and hurriedly responded: "Well, if there are really people inside, we can't go in now." At the very least, we must find out whether the people inside are friends or foes! ”

"That's it!"

Shen Yan secretly praised that if this kind of thing is put on someone else's body, under the gains and losses, it is either eager to enter immediately; Either that, or a big disappointment. But Tang Haotian came back to his senses in shock, and instead made the most correct reaction.
