After several consecutive shots, the bullets were blocked by the giant bear's earthy yellow shield, and Han Tianyu didn't plan to continue wasting bullets.

"Whoosh!" He excited the Hidden Arrow missile on his arm.

A missile dragged a long tail flame straight towards the giant bear!

"Roar!" The giant bear let out a roar, and at the same time, a ball of light spat out of its mouth, and the missile was blown up in the air!

"Boom!" The shock wave of Bào Zhà swept through the entire cave, and Han Tianyu also had to find cover to dodge.

"This giant bear has wisdom!" Han Tianyu secretly said in his heart, he obviously felt that the giant bear was not attacking by instinct, but that it felt the threat from the missile, so he took the initiative to intercept it.

Facing a fierce beast with wisdom, Han Tianyu's expression also became serious, he knew that it might not be so easy for him to escape from this cave smoothly!

"Roar!" The giant bear didn't give Han Tianyu much time to think, it roared and pounced on Han Tianyu.

"Da Da Da ......" The qiāng weapon in Han Tianyu's hand couldn't stop the giant bear at all, seeing that it had rushed in front of him, Han Tianyu was forced to helplessly throw the step qiāng in his hand aside, and then took out his melee weapon from behind his back-high-frequency vibration knife.

This melee weapon is more devastating than the Hyperalloy knives found in regular warframes, and its blade can vibrate at a high frequency of 100,000 times per second, making it more effective in cutting and lethal in combat.

Facing the giant bear that pounced, Han Tianyu dodged and dodged the giant bear's pounce, and at the same time, the vibrating knife in his hand stabbed the giant bear's ribs.

"Snort......" The giant bear's ribs were stabbed by Han Tianyu with a wound!

Although the giant bear has a shield on its body, its shield only seems to react to high-speed incoming objects, and no matter how fast Han Tianyu swings his knife, it can't be as fast as a bullet fired by electromagnetic force, so the blade he swung was not intercepted by the giant bear's shield.

Although the giant bear's fur also has strong defense, it is still unable to withstand the damage caused by the vibrating knife in the face of the blade that vibrates 100,000 times per second.

However, although Han Tianyu's knife made the giant bear see blood, it did not hurt its vital point, and this injury only stimulated the fierceness of the giant bear.

At the same time, more importantly, the giant bear has intelligence, it has now realized that Han Tianyu's vibrating knife is a weapon that can threaten him, so it has become more cautious when fighting Han Tianyu, this giant bear with a length of more than three meters actually distanced itself from Han Tianyu, and instead attacked Han Tianyu by spitting energy balls, and it itself no longer attacks in close quarters!

"Boom, boom, boom......" The earthy yellow ball of light chased Han Tianyu's ass and blasted wildly, chasing Han Tianyu in a hurry, unable to get close to the giant bear at all, and sometimes even had to rely on the extra power provided by the jetpack to barely avoid the giant bear's attack.

Between chasing and fleeing, Han Tianyu's brows furrowed, he knew that if he held for a long time, he would lose, although he could still dodge the giant bear's attack now, but that was based on whether he activated the jetpack and instantly opened the distance.

Once the jetpack's energy is exhausted, it will be difficult for Han Tianyu to dodge the giant bear's attack every time!

The battle continued, Han Tianyu held on minute after minute, and at the same time he was racking his brains to find countermeasures, but unfortunately, the giant bear was too cautious, even if Han Tianyu sold a flaw, it refused to get close, and relied on energy attacks from a distance to consume Han Tianyu's physical strength.

Although as the attacking side, the giant bear's consumption is greater, don't forget its size, the energy he can accumulate is definitely much more than the fuel in Han Tianyu's jetpack!

Although he wanted to get out of the situation in front of him, the giant bear had always maintained a long-range attack, and it didn't try to get close to Han Tianyu at all, and although Han Tianyu also had a long-range attack, his attack couldn't threaten the other party at all.

Seeing that the fuel in the jetpack was getting less and less, and even the energy battery of the power armor was lost by more than two-thirds, Han Tianyu's heart also lifted, because once the energy of the power armor was exhausted, then this thing would be a living coffin, it would no longer provide any assistance to Han Tianyu, and it would trap Han Tianyu inside and let the giant bear attack.

It stands to reason that the power armor needs to be full of energy before each mission, in this case, the armor can support about a week's combat time, but the problem is that Han Tianyu was performing a certain mission before, and when he was captured, the energy of the armor itself was not much, plus the attrition of the high-intensity battle in front of him, so the remaining energy of this suit of armor was not too much.

"Roar!" With a roar, the bear spat out a ball of light again.

"Boom!" Han Tianyu tried his best to dodge, and the light cluster hit the rock wall less than two meters away from him, and dissolved a large crater there.

"It's not realistic to kill it at all, you can only rely on luck and run away!" In the end, as soon as Han Tianyu gritted his teeth, he gave up his plan to kill the giant bear, and then threw a few energy grenades and smoke grenades at the giant bear.

"Bang! Bang! Boom......" The giant bear exploded two energy grenades in the air, but one energy grenade was still near it, and the smoke grenades began to release white smoke.

"Drop!" Han Tianyu switched the helmet's viewing mode, his vision darkened, and his helmet no longer provided him with the scene in front of him based on optical imaging, but used the signal fed back by sonar to make a three-dimensional composition.

In this way, the scene in Han Tianyu's helmet display changed, everything changed to the appearance of lines, and the giant bear lost its target in the thick smoke, and it could only attack the direction where Han Tianyu was roughly located according to the information fed back by sound.

And Han Tianyu took advantage of this opportunity to turn on the jetpack with all his might, he no longer saves fuel at this time, and only pursues speed!

"Huh!" Han Tianyu's figure flashed past the giant bear's side, although the giant bear immediately launched an attack after hearing the sound, but because the vision was blocked by thick smoke, the giant bear's attack was no longer accurate, so it did not pose a threat to Han Tianyu.

According to the vision formed by the lines, Han Tianyu flashed past the giant bear, and then rushed towards the exit of the cave in the distance.

A moment later, Han Tianyu rushed out of the cave, and he finally saw the blue sky again, and behind him was the roar of a giant bear's rage.

After "Stampede ......" turned off the jetpack, Han Tianyu rushed down the hill quickly, the giant bear could catch up at any time, and he had to leave this dangerous place quickly.
